A lawyer in Turkey advising foreign investors on the 2026 tax package now works from three layers of law rather than one. On 24 April 2026 the President set out a broad framework of tax measures aimed at high-net-worth individuals, exporters, and multinational groups. On 4 June 2026 the operative parts of that framework became law when Law No. 7582 was published in the Official Gazette No. 33270. On 4 July 2026 the Ministry of Treasury and Finance published four General Communiqués in the Official Gazette No. 33300 that set the procedure for each of the main measures, and in September 2026 the Revenue Administration followed with an official guide to the twenty-year exemption. The distinction between the announcement and the enacted law matters, because the statute is narrower and more precise than the April headlines and several figures from April did not pass. The distinction between the statute and the Communiqués matters too, because the Communiqués added procedural conditions, above all a formal Exemption Certificate with a fixed deadline, that a client cannot read out of the statute. This guide explains what Law No. 7582 contains, what the Communiqués added, which announced measures were not enacted, and how the pieces fit together for a foreign investor planning a move, a repatriation, or a restructuring.
From Announcement to Statute: What Changed Between April and June
An Istanbul Law Firm reading the package today has to hold the political programme and the enacted text apart. The 24 April announcement described seven broad axes: a twenty-year exemption for new residents, a wealth amnesty, a one per cent inheritance rate, an Istanbul Finance Center expansion, dramatic corporate tax cuts for exporters, a One-Stop Office for investors, and a full exemption for software and engineering exports. Law No. 7582, accepted by the Grand National Assembly on 21 May 2026 and published on 4 June 2026, enacted some of these faithfully, reshaped others during drafting, and left several as policy intentions without statutory form. A foreign investor who plans against the April headlines rather than the June statute risks building on figures that no longer exist.
A Turkish Law Firm summarising the enacted measures lists them precisely. Law No. 7582 inserted a new Mükerrer Article 20/D into the Income Tax Law, exempting twenty years of foreign-source income for qualifying new residents; amended Article 16 of the Inheritance and Transfer Tax Law to tax inheritance at one per cent for those beneficiaries; added Provisional Article 19 to the Corporate Tax Law to create the 2026 wealth amnesty; defined the qualified service centre in the Foreign Direct Investment Law and granted it, together with transit trade, a deduction of ninety-five to one hundred per cent under Article 10 of the Corporate Tax Law; added a wage exemption for qualified service centre personnel to Article 23 of the Income Tax Law; set a 12.5-point reduction in the corporate tax rate on production earnings under Article 32; extended the Istanbul Finance Center incentive period from 2031 to 2047; lengthened the public-debt deferral period and raised the unsecured deferral ceiling; and made several research-and-development and start-up changes. Each is examined below with its figures stated as the statute and the Communiqués state them.
An English speaking lawyer in Turkey is equally careful about what did not become law. The April headline of a nine per cent corporate tax rate for manufacturer-exporters and fourteen per cent for other exporters does not appear in Law No. 7582; the enacted corporate rate measure is a 12.5-point reduction on production earnings, a different instrument with different conditions. The announced increase of the software, engineering, architecture, and design export deduction from eighty to one hundred per cent is not among the articles of Law No. 7582; that deduction remains at its current level. The One-Stop Office, the project-based stabilisation clause, and the Terminal İstanbul project were described as programme objectives and do not take the form of enacted provisions in this statute. A careful analysis keeps them in the category of announced policy until and unless they are legislated. Practice may vary by authority and year.
The Implementing Layer: The Four General Communiqués of 4 July 2026 and the Revenue Administration Guide
A Turkish Law Firm treats 4 July 2026 as the second date every client should know, because on that day the Ministry of Treasury and Finance published, in a single issue of the Official Gazette, No. 33300, the four Communiqués that turned the statute into a procedure. Income Tax General Communiqué No. 333 implements the twenty-year exemption under Article 20/D and creates the Exemption Certificate. Income Tax General Communiqué No. 334 implements the wage exemption for qualified service centre personnel. The General Communiqué on Bringing Certain Assets into the Economy, Series No. 1, implements the wealth amnesty under Provisional Article 19, with its three annexed forms. And Communiqué Series No. 26 amending the Corporate Tax General Communiqué implements the transit trade and qualified service centre deductions, the production-rate reduction, and the related changes to the domestic minimum corporate tax computation. All four entered into force on publication.
An Istanbul Law Firm explains why these Communiqués carry more weight than implementing rules usually do, because here they added conditions rather than merely describing procedure. Communiqué No. 333 made the twenty-year exemption dependent on a certificate that must be applied for by a deadline the statute never mentioned: the end of the calendar year in which the person becomes resident, extended to the end of February for November and December arrivals, with a late application refused outright. The wealth amnesty Communiqué fixed the declaration channel as the bank rather than the tax office, set a ten-day window for converting declared assets into a committed instrument, required assets carried in physically to be deposited by the end of the first business day after customs, and spelled out the exact conditions on which the audit protection depends. Communiqué Series No. 26 clarified that the production measure is a reduction of 12.5 points in the rate rather than a free-standing rate, and that the new deductions are taken into account in computing the domestic minimum corporate tax. A client who read only the statute in June would have missed every one of these.
An English speaking lawyer in Turkey also points clients to the Revenue Administration's own guide on the twenty-year exemption, published in September 2026 as Publication No. 616 with an accompanying infographic. The guide restates Communiqué No. 333 in question-and-answer form, reproduces its worked examples in tables, and confirms the one per cent inheritance rate for exemption beneficiaries. It adds no new rule, but it is the administration's own plain-language account of how the regime operates, and in client correspondence it is the document most useful to cite alongside the Communiqué itself. Where this guide refers to official examples below, it refers to the Communiqués and to the Revenue Administration guide, all of which are public. Practice may vary by authority and year, and the Communiqués and the guide are the current reference points for every procedural question.
The Twenty-Year Foreign Income Exemption (Article 20/D) and the Exemption Certificate
Turkish lawyers who advise inbound relocation treat the twenty-year exemption as the centre of gravity of the whole package. Law No. 7582 inserted Mükerrer Article 20/D into the Income Tax Law (Law No. 193). A natural person who becomes a Turkish tax resident, and who in the three calendar years before becoming resident had neither a domicile in Turkey nor a tax liability in Turkey, may keep foreign-source income and earnings outside the Turkish income tax base for twenty years. No annual return is filed for the exempt income, the costs of earning it are not deductible, and foreign taxes paid on it are not credited. Where the conditions are later found not to have been met, the untaxed amounts are treated as lost revenue and collected with a tax loss penalty and default interest. The provision applies to persons who become resident from 1 January 2026, and only natural persons qualify.
A lawyer in Turkey explains the two features that Communiqué No. 333 added and that decide most cases in practice. The first is the Exemption Certificate, formally the Certificate of Exemption for Income and Earnings Derived from Abroad in Annex 1 of the Communiqué, issued by the competent tax office on the taxpayer's petition after it checks three things: that the applicant is resident, that the three preceding calendar years were clean of both domicile and liability, and that the application is in time. The certificate's own text makes the applicant personally liable for tax, penalty and interest if facts contrary to the petition later emerge. The second is the deadline: the end of the calendar year of residency, or the end of the following February for a person who becomes resident in November or December. The Communiqué's Example 2 shows a person resident from 2 March 2028 who applied on 1 May 2030, satisfied every substantive condition, and was refused on timing alone. The three-year look-back is measured in whole calendar years, prior Turkish rental, investment or capital gain liabilities do not disqualify, and prior Turkish employment or commercial income does, as Examples 6 and 7 show.
An Istanbul Law Firm also flags the companion inheritance benefit, because the same statute amended Article 16 of the Inheritance and Transfer Tax Law (Law No. 7338). For a person who benefits from the Article 20/D exemption, transfers by inheritance within the exemption period are taxed at one per cent, against an ordinary progressive scale that rises into double digits on larger estates; the Revenue Administration guide confirms the rule. For the complete treatment of residency, the look-back, the certificate application, the scope of exempt income, and all thirteen official examples, see our twenty-year foreign income exemption guide. Practice may vary by authority and year, and the certificate deadline in particular should be calendared from the date of residency at the outset of any plan.
The 2026 Wealth Amnesty (Provisional Article 19) and Its Declaration Procedure
A Turkish Law Firm treats the wealth amnesty as the counterpart to the income exemption: one addresses future income, the other the existing stock of wealth. Law No. 7582 added Provisional Article 19 to the Corporate Tax Law (Law No. 5520). Real and legal persons may declare money, gold, foreign currency, securities, and other capital market instruments held abroad, or held in Turkey but unrecorded in their books, by 31 July 2027, a deadline the President may extend by up to one year in total. The rate is five per cent of the declared value, reduced to four, three, two, one or zero per cent according to whether the assets are committed for one to five years to time deposits, government domestic debt securities, lease certificates, or venture capital funds, with half a point added for declarations from 1 January 2027 and a further half point in any extension period. Real estate is outside the scope, although an excluded foreign asset may be converted into an in-scope asset before the deadline and then declared.
An English speaking lawyer in Turkey sets out what the Series No. 1 Communiqué added, because the procedure is where declarations succeed or fail. The declaration is made to a bank, or to an intermediary institution for securities only, on the Annex 1 form in two copies; the bank certifies one copy, asks for no documents on the assets, collects the rate at source, and files its own Annex 3 return by the fifteenth of the following month. A reduced rate requires the Annex 2 commitment at the time of declaration, and the committed instrument must receive the assets within ten days of transfer. Foreign assets must reach a Turkish account within two months of each declaration, and assets carried in physically must be deposited by the end of the first business day after customs. Each month is a separate period, corrections follow fixed rules, and nothing can be corrected after 31 July 2027. A company must record the assets and open a special fund account locked for two years. The protection against examination and assessment covers the declared amount, applies only if every one of these conditions is met, and is unavailable for a declaration made after an examination has formally begun.
A lawyer in Turkey draws the lesson the Communiqué's examples teach, which is that breaching a condition loses the protection even where it does not attract a penalty: the difference between the reduced rate and five per cent is collected with default interest, no tax loss penalty is charged, but the shelter over the declared amount is gone. For the full mechanics, the ownership rules for assets held through representatives or foreign companies, the valuation and bookkeeping rules, and all eight official examples, see our 2026 wealth amnesty guide. Practice may vary by authority and year, and a client weighing a declaration should decide early, because the rate rises in 2027 and the protection cannot be bought once an examination is under way.
The Istanbul Finance Center: Extension to 2047 and the New Deductions
An Istanbul Law Firm advising on the financial centre starts with the single most important change Law No. 7582 made to it: the incentive period was extended. The Istanbul Finance Center Law (Law No. 7412) previously ran its core deduction to 2031; the statute replaced that horizon with 2047 and adjusted the related period reference from five years to twenty. For an institution weighing whether to take up a participant certificate, this transforms the planning horizon, because the central benefit now has a two-decade runway rather than a window closing within a few years. The financial service export deduction available to participants, applied in full under the transitional provision, now extends on that longer basis.
A Turkish Law Firm then turns to the two new deductions Law No. 7582 created under Article 10 of the Corporate Tax Law and that Communiqué Series No. 26 now governs in detail. The first concerns transit trade: earnings from buying goods abroad and selling them abroad without bringing them into Turkey, or from intermediating such trades, may be deducted at ninety-five per cent, rising to one hundred per cent for institutions operating in the Istanbul Finance Center or in industrial zones approved by presidential decision, provided the earnings are transferred to Turkey by the corporate tax return deadline and shown separately on the return. The second concerns the qualified service centre, defined by Law No. 7582 in the Foreign Direct Investment Law (Law No. 4875) for capital companies that provide management and similar services to related parties operating in at least three countries: such a centre may deduct ninety-five per cent of the foreign-source earnings from its qualifying activity, again rising to one hundred per cent inside the centre or approved zones, for twenty accounting periods counted from the period in which it begins operating. The Communiqué's own illustration is a centre that begins on 15 October 2026 and benefits for the periods 2026 to 2045. Both deductions apply to earnings from accounting periods beginning on or after 1 January 2026, in returns filed from 1 July 2026.
An English speaking lawyer in Turkey adds the personnel measure that Communiqué No. 334 implements, because for a group deciding where to place staff it is often decisive. Law No. 7582 added a new item to Article 23 of the Income Tax Law exempting from income tax the wages of qualified service personnel employed at a qualified service centre up to three times the gross minimum wage, and up to five times the gross minimum wage where the centre operates in the Istanbul Finance Center or in an approved industrial zone. The exempt portion is also exempt from stamp duty, and the portion above the threshold is taxed under the general rules. The qualified service centre is the enacted form of what the April announcement loosely called a regional headquarters incentive; the statute creates no free-standing regional headquarters category. For the umbrella treatment of the centre, its participants, and the qualified service centre regime, see our Istanbul Finance Center hub and our qualified service centre guide. Practice may vary by authority and year, and the industrial zones eligible for the one hundred per cent rate are those designated by presidential decision at the relevant time.
The Corporate Tax Picture: A 12.5-Point Reduction on Production Earnings, Not Nine or Fourteen
A lawyer in Turkey has to be exact here, because this is where the gap between announcement and statute is widest and where a careless reading does real harm. The April programme spoke of cutting the corporate tax rate to nine per cent for manufacturer-exporters and fourteen per cent for other exporters. That formulation did not become law; it was dropped at the parliamentary committee stage. What Law No. 7582 enacted, by adding a new paragraph to Article 32 of the Corporate Tax Law, is a reduction of the corporate tax rate on production earnings by 12.5 points, up from the one-point reduction that previously applied. The reduction is available to a company holding an industrial registry certificate and actually engaged in production, on the earnings it derives purely from that production, and to a company engaged in agricultural production on its production earnings. It applies to earnings from the 2027 tax period onwards; for 2026 the one-point reduction continues.
A Turkish Law Firm explains the mechanism as Communiqué Series No. 26 does, because the difference between a rate and a point reduction matters in the arithmetic. Turkey's general corporate tax rate is twenty-five per cent. A 12.5-point reduction applied to that rate produces a 12.5 per cent charge on qualifying production earnings, which is why the measure is often described as a 12.5 per cent rate; but the Communiqué's example shows that the reduction is applied to whatever rate otherwise applies, so that a company already enjoying the two-point reduction for a public listing applies the 12.5-point production reduction on top of it. Exporters continue to benefit from the pre-existing five-point reduction on export earnings, bringing those to twenty per cent, but a company whose production earnings already carry the 12.5-point reduction does not also apply the five-point export reduction to the same earnings; each stream takes one regime. Earnings outside the production activity remain at the general rate.
An Istanbul Law Firm draws the practical conclusion for foreign-owned manufacturers. The benefit is genuine but conditional and prospective: it requires the industrial registry certificate and actual production, it is confined to production earnings, and it begins with the 2027 tax period rather than immediately. The accounting separation of production from non-production earnings is therefore not a formality but the thing that determines how much of the profit reaches the reduced rate, and a company should design that separation during 2026 so that the first qualifying return is clean. A foreign investor evaluating a Turkish manufacturing footprint should model 12.5 per cent on production earnings from 2027, twenty per cent on export earnings outside production, and twenty-five per cent on everything else, and should not assume the nine and fourteen per cent figures from the announcement. Practice may vary by authority and year.
How the Global Minimum Tax Constrains the Benefits
An English speaking lawyer in Turkey cannot present the corporate incentives without the global minimum tax, because for large groups it sets a floor that the incentives cannot pierce. Turkey enacted the local and global minimum complementary corporate tax through Law No. 7524, published in the Official Gazette on 2 August 2024. It targets multinational groups whose ultimate parent reports annual consolidated revenue of 750 million euro or more in at least two of the four preceding periods, in line with the OECD's global rules. The global minimum rate is fifteen per cent; where a group's effective rate in a country falls below that, a top-up is collected to reach it. The income inclusion rule applied to fiscal years from 1 January 2024 and the undertaxed profits rule from 1 January 2025.
A Turkish Law Firm explains the consequence for the package's incentives. For a multinational group within the 750 million euro scope, a low Turkish effective rate produced by the production reduction, the transit trade deduction, or the qualified service centre deduction can be met by a top-up that brings the effective rate back to fifteen per cent, whether through Turkey's own complementary tax or through another country's rules. Turkey's domestic minimum complementary tax, also introduced by Law No. 7524 and effective for periods from 2025, is designed so that Turkey itself collects that top-up rather than ceding it abroad. The practical effect is that the most generous deductions in Law No. 7582 deliver their full benefit to groups below the threshold, while in-scope groups should model the incentives against the fifteen per cent floor rather than assume the headline rate.
A lawyer in Turkey adds a separate point from Communiqué Series No. 26 that concerns the purely domestic minimum corporate tax, which applies to Turkish companies generally and is distinct from the global rules. The Communiqué adds the transit trade deduction, the qualified service centre deduction, and the Istanbul Finance Center financial service export deduction to the list of deductions taken into account in computing the base of the domestic minimum corporate tax, so that these deductions are not clawed back by that domestic floor. For a Turkish company below the global threshold this matters: the new deductions reduce both the ordinary corporate tax and the domestic minimum computation, and the benefit is real at both levels. For an in-scope multinational, the global fifteen per cent floor still governs. Conflating these two minimum taxes is a common error, and the distinction should be drawn at the outset of any structuring exercise. Practice may vary by authority and year.
What Was Announced But Not Enacted
An Istanbul Law Firm earns its fee partly by telling clients what is not there. Three prominent items from the April programme are not enacted provisions of Law No. 7582, and a foreign investor should treat them accordingly. The first is the nine and fourteen per cent corporate tax rates for exporters, which were not legislated in that form; the enacted instrument is the 12.5-point production reduction. The second is the increase of the export-services deduction for software, engineering, architecture, and design from eighty to one hundred per cent. That deduction exists under the Income Tax Law and the Corporate Tax Law and currently stands at eighty per cent following a 2023 amendment, but the increase to one hundred per cent is not among the articles of Law No. 7582 and should not be presented to clients as enacted.
A Turkish Law Firm is equally clear about the administrative and protective measures. The One-Stop Office, described in April as a single coordinated point for company formation, work and residence permits, tax and social security, and land, incentive, and environmental procedures under the coordination of the Presidency's Investment and Finance Office, is a programme objective rather than a new statutory mechanism in this law. A version of a one-stop arrangement already exists within the Istanbul Finance Center under its own legislation, coordinated by the Finance Office, but the broad investor-wide office described in April is not legislated here. The project-based stabilisation clause, offering protection against future tax changes for qualifying large investments, and the Terminal İstanbul project at the former airport site were likewise described as objectives, with the announcement using the language of measures to be taken rather than measures enacted.
An English speaking lawyer in Turkey notes the one area where a start-up measure did pass, to avoid the opposite error of dismissing everything not on the headline list. Law No. 7582 made changes in the research-and-development field, broadening the income tax treatment of share-based awards granted by qualifying technology start-ups to their employees and easing the use of convertible-debt arrangements for badged non-public companies, alongside fee relief for certain incubator digital companies. These are real, enacted changes, even though they sit outside the seven headline axes. The discipline the investor needs is neither to assume the announcement is law nor to assume nothing passed, but to check each measure against the enacted text. A measure that is announced but not legislated may still arrive in a later statute, so the right posture is to monitor rather than to dismiss; but it cannot be relied on, structured around, or presented to a client as a current entitlement until it appears in an enacted provision with an effective date. Practice may vary by authority and year, and the status of each announced-but-unlegislated measure should be reviewed as further legislation is published.
The Effective Dates That Govern Planning
A lawyer in Turkey organises the package around its dates, because the benefits do not all begin at once and a plan built on the wrong date fails quietly. Law No. 7582 entered into force on 4 June 2026, and the four General Communiqués on 4 July 2026. The twenty-year foreign income exemption applies to income derived from 1 January 2026 by those treated as resident, and the Exemption Certificate for a person who became resident in 2026 must be applied for by 31 December 2026, or by the end of February 2027 for a November or December arrival. The one per cent inheritance rate, tied to that exemption, took effect on publication of the statute. The wealth amnesty opened on 4 June 2026 and runs to its 31 July 2027 declaration deadline, subject to extension; the half-point rate increase applies to declarations from 1 January 2027, the two-month transfer rule runs from each declaration, and the ten-day conversion rule runs from each transfer.
A Turkish Law Firm continues the calendar into the corporate measures. The transit trade and qualified service centre deductions apply to accounting periods beginning on or after 1 January 2026, in returns filed from 1 July 2026, and the qualified service centre's twenty accounting periods run from the period in which it begins operating. The 12.5-point production reduction applies from the 2027 tax period, not 2026, so a manufacturer cannot claim it on current-year earnings and should use 2026 to prepare its accounting separation. The qualified service centre wage exemption applies from the entry into force of the statute. The Istanbul Finance Center extension to 2047 took effect on publication, lengthening rather than delaying the existing benefit. The public-debt deferral changes, a deferral period raised from thirty-six to seventy-two months and an unsecured deferral ceiling raised to one million Turkish lira, took effect on publication and are immediately useful to a company managing an existing public liability while it restructures.
An Istanbul Law Firm uses the calendar to sequence client steps, and the two most time-critical items are the ones the Communiqués created. A person who became resident in 2026 and has not yet applied for the Exemption Certificate has a deadline of 31 December 2026, or the end of February 2027 if resident from November or December; after that the first year's exemption is lost with no provision for a late application. A person weighing a wealth amnesty declaration should note that the rate rises by half a point on 1 January 2027 and that no declaration can be corrected after 31 July 2027. The corporate deductions require the 2026 bookkeeping to be correct for returns from July 2026, and the production reduction is a 2027 matter to prepare for during 2026. A plan that respects these dates captures each benefit at the first lawful opportunity; a plan that treats the package as a single switch thrown on 4 June 2026 misfires on the measures that begin later and misses the measures that close earlier. Practice may vary by authority and year, and each date should be reconfirmed against the statute and the Communiqués at the time of filing.
Documentation: The Evidence Each Measure Requires
An English speaking lawyer in Turkey treats documentation as the core of the engagement rather than an afterthought, because each measure places the burden of proof on the taxpayer and the Communiqués now say what the administration will look at. For the twenty-year exemption, the petition for the Exemption Certificate is the document the certificate refers back to, and the tax office checks residency, the three clean look-back years, and timeliness against its own registers; in our filings the practical approach is to anticipate those three checks with evidence of present residency, foreign residence and tax confirmations for each of the three years, and a clear statement of any prior Turkish income showing that it fell within the protected passive categories. Building this file before residency is established is far easier than reconstructing it under examination years later, and the certificate's own liability clause makes accuracy the applicant's responsibility.
A Turkish Law Firm sets out the parallel requirements for the wealth amnesty, which the Series No. 1 Communiqué makes largely a matter of forms and receipts. The bank asks for no documents on the declared assets, so the declarant's own file is what protects the declaration: the bank's certified copy of the Annex 1 form, the Annex 2 commitment, the bank receipts or transaction forms evidencing transfer within two months and conversion within ten days, customs documents for any physical import, the accounting entries and special fund account for a company, and, where assets were held through a representative or a foreign company under Article 8 of the Communiqué, the evidence of beneficial ownership that an examiner may demand years later. For the corporate deductions, the file is different again: an industrial registry certificate and production records for the 12.5-point reduction, and, for the transit trade and qualified service centre deductions, evidence that the counterparties sit outside Turkey, that the earnings were repatriated by the return deadline, that the deductions are shown separately on the return, and that the centre meets its definitional conditions.
Turkish lawyers who handle cross-border matters add the authentication layer that foreign documents require. Foreign certificates, filings, and corporate records intended for use in Turkey generally need apostille authentication under the 1961 Hague Convention and sworn translation, and treaty benefits that interact with the exemption require a certificate of tax residence. None of this is exotic, but all of it takes time, and the difference between a client who assembled the file in advance and one who began after a query from the administration is usually the difference between a position that holds and one that is conceded. An Istanbul Law Firm adds a word on timing, because the order in which the file is built matters as much as its contents: for the exemption, the three-year evidence is gathered before residency so that the certificate petition is complete and in time; for the amnesty, the Turkish bank account and the committed instrument are arranged before the Annex 1 filing so that the two-month and ten-day windows can be met; for the corporate deductions, the 2026 bookkeeping is correct in real time because the returns fall due from July 2026. Practice may vary by authority and year, and the documentary expectations of an individual tax office or bank should be confirmed at the time of filing.
Common Mistakes in Reading the 2026 Package
An Istanbul Law Firm sees the same errors repeatedly, and the most damaging remains planning against the announcement rather than the statute. A client who fixes on the nine or fourteen per cent export rates, or on the full software-export exemption, is planning against figures that did not become law. The second error is treating the One-Stop Office, the stabilisation clause, or the Terminal İstanbul project as enacted mechanisms on which a structure can rely; they are policy objectives, and a plan that depends on them depends on legislation that does not yet exist. The third error, new since July, is reading the statute without the Communiqués: a client who knows Article 20/D but not Communiqué No. 333 does not know that a certificate is required or that it has a deadline, and a client who knows Provisional Article 19 but not the Series No. 1 Communiqué does not know that the bank, not the tax office, is the counterparty or that a ten-day conversion window exists.
A Turkish Law Firm flags the date errors next, because the Communiqués made several of them fatal. Missing the Exemption Certificate deadline forfeits the exemption for the year with no provision for a late application, as the Communiqué's Example 2 shows. Counting the three-year look-back in months rather than calendar years, so that a departure in late 2024 is treated as producing eligibility in 2027, fails as Example 4 shows. Assuming that Turkish wages taxed at source do not count as a liability fails as Example 6 shows. Declaring under the amnesty before the Turkish banking arrangements are in place, so that the two-month transfer or the ten-day conversion is missed, loses the audit protection as Example 8 shows for a broken commitment. Assuming the whole package switched on with publication on 4 June 2026 misstates the production reduction, which begins in 2027, and the corporate deductions, which run through returns from July 2026.
An English speaking lawyer in Turkey closes the list with the scope errors, which are the quietest and the most common. Assuming that work performed from Turkey for foreign clients is foreign-source income fails as Example 10 of Communiqué No. 333 shows; the service is performed in Turkey and the income is taxable. Assuming that Turkish rental or dividend income becomes exempt once the certificate is held fails as Examples 9 and 11 show. Assuming that a wealth amnesty declaration shelters unrelated adjustments found on examination fails as Example 7 of the Series No. 1 Communiqué shows; only the amount demonstrably connected to the declared assets is protected. And assuming that the Exemption Certificate is a shield against later findings fails as Example 12 shows; the certificate is cancelled retrospectively if a disqualifying liability in the look-back years emerges. Each of these is avoidable with a correct analysis before the filing, and none is curable afterward. Practice may vary by authority and year, and a client's position should be reviewed against the Communiqués' examples before any petition or declaration is filed.
How a Turkish Law Firm Approaches the Package as a Whole
A Turkish Law Firm begins by placing the client in one of the profiles the package was built for, because the measure that fits follows from the profile. The returning member of the diaspora, who left long enough ago that the three calendar years before return are clean, typically uses the income exemption, the one per cent inheritance rate and the wealth amnesty together, and the plan is one of clean re-entry with the certificate deadline and the declaration window calendared from the outset. The foreign national with no Turkish tax history, whether a retiree, an investor, a remote professional or an entrepreneur with a business abroad, uses the income exemption to convert a relocation into a long horizon of untaxed foreign income, with the classification of each income stream settled against the Communiqué's examples before the move. The multinational group managing functions for related parties across several countries is the intended user of the qualified service centre and its wage exemption, read against the global minimum tax where the group is in scope. The trading group routing goods between third countries is the user of the transit trade deduction, and the foreign-owned manufacturer with an industrial registry certificate is the user of the 12.5-point production reduction from 2027.
An Istanbul Law Firm is equally candid about who the package does not transform. A multinational group above the global minimum tax threshold will often find the corporate incentives equalised back to fifteen per cent, so its decision rests on non-tax factors as much as on rate. An individual who cannot show a clean three-year history, or who became resident in 2026 and missed the certificate deadline, will not have the income exemption regardless of how the relocation is framed. A declarant who cannot meet the two-month transfer, the ten-day conversion or the two-year fund lock should not buy a reduced amnesty rate that will later be unwound. Naming the misfit honestly at the outset saves a client from building a plan on a benefit that will not arrive.
A lawyer in Turkey closes with the discipline that the package rewards. The enacted statute is more precise and in places more modest than the announcement, and the Communiqués are more demanding than the statute; the investor who plans against all three layers rather than the April headlines is the one who captures the benefits cleanly. That means using the enacted figures, twenty years, one per cent, five to zero per cent, ninety-five to one hundred per cent, 12.5 points, 2047, respecting the effective dates and the new deadlines, and building the documentary file before it is needed. Our materials are organised the same way: the twenty-year income exemption and its certificate in our foreign income exemption guide; the wealth amnesty and its declaration procedure in our wealth amnesty guide; and the financial centre, its participants, and the qualified service centre regime in our Istanbul Finance Center hub. This page is the umbrella over those materials. Done with that discipline, the 2026 package is one of the more significant openings Turkish law has offered cross-border clients in a decade. Practice may vary by authority and year, and every element should be confirmed against the statute, the Communiqués, and the Revenue Administration's current guidance.

Frequently asked questions
- Is the 2026 foreign investor tax package now law, and is it in force? Yes on both counts for its operative parts. Law No. 7582 was accepted by the Grand National Assembly on 21 May 2026 and published in the Official Gazette No. 33270 on 4 June 2026, entering into force on publication except where a later date is specified. On 4 July 2026 the Ministry of Treasury and Finance published four General Communiqués in the Official Gazette No. 33300 setting the procedure for the twenty-year exemption, the qualified service centre wage exemption, the wealth amnesty, and the corporate deductions and production reduction. Several items from the April announcement were not enacted.
- What are the four Communiqués of 4 July 2026? Income Tax General Communiqué No. 333, implementing the twenty-year foreign income exemption and creating the Exemption Certificate; Income Tax General Communiqué No. 334, implementing the wage exemption for qualified service centre personnel; the General Communiqué on Bringing Certain Assets into the Economy, Series No. 1, implementing the wealth amnesty with its Annex 1, 2 and 3 forms; and Communiqué Series No. 26 amending the Corporate Tax General Communiqué, implementing the transit trade and qualified service centre deductions and the production reduction. All entered into force on publication.
- Did the corporate tax rate fall to nine per cent for exporters? No. The nine per cent manufacturer-exporter and fourteen per cent other-exporter rates from the announcement were dropped at the committee stage and were not legislated. What Law No. 7582 enacted is a reduction of 12.5 points in the corporate tax rate on the production earnings of companies holding an industrial registry certificate and actually engaged in production, applying from the 2027 tax period and producing a 12.5 per cent rate against the twenty-five per cent general rate. For 2026 the previous one-point reduction continues.
- What is the twenty-year foreign income exemption? Under Mükerrer Article 20/D of the Income Tax Law, a person who becomes a Turkish tax resident, and who in the three calendar years before becoming resident had neither a domicile nor a tax liability in Turkey, may keep foreign-source income outside the Turkish tax base for twenty years. It applies to income derived from 1 January 2026 by those treated as resident. Under Communiqué No. 333 the exemption requires an Exemption Certificate obtained from the tax office within a deadline.
- What is the Exemption Certificate and when must it be applied for? It is the Certificate of Exemption for Income and Earnings Derived from Abroad in Annex 1 of Communiqué No. 333, issued by the competent tax office on the taxpayer's petition after checking residency, the three clean look-back years, and timeliness. The application must be made by the end of the calendar year in which the person becomes resident, extended to the end of February of the following year for a person who becomes resident in November or December. The Communiqué's Example 2 shows a late applicant being refused on timing alone.
- What is the one per cent inheritance rate? Law No. 7582 amended Article 16 of the Inheritance and Transfer Tax Law so that, for a person benefiting from the Article 20/D exemption, transfers by inheritance within the exemption period are taxed at one per cent, against an ordinary progressive scale that rises into double digits on larger estates. The Revenue Administration guide confirms the rule. It is a companion benefit tied to the same qualification.
- What is the 2026 wealth amnesty and what does it cost? Under Provisional Article 19 of the Corporate Tax Law, real and legal persons may declare money, gold, foreign currency, securities, and other capital market instruments held abroad or unrecorded in Turkey to a Turkish bank by 31 July 2027. The rate runs from five per cent down to zero according to a one-to-five-year commitment to hold the assets in time deposits, government securities, lease certificates or venture capital funds, with half a point added for declarations from 1 January 2027 and a further half point in any extension period. Real estate is outside scope. Foreign assets must reach a Turkish account within two months of declaration, and committed assets must be placed in the instrument within ten days of transfer.
- Did the software and engineering export exemption rise to one hundred per cent? Not under Law No. 7582. The export-services deduction for software, engineering, architecture, and design exists under the Income Tax Law and Corporate Tax Law and currently stands at eighty per cent following a 2023 amendment. The announced increase to one hundred per cent is not among the articles of Law No. 7582 and should not be treated as enacted.
- What changed for the Istanbul Finance Center? Law No. 7582 extended the core incentive horizon from 2031 to 2047 and adjusted the related period reference from five to twenty years. It also created, under Article 10 of the Corporate Tax Law, a transit trade deduction and a qualified service centre deduction of ninety-five per cent, rising to one hundred per cent inside the centre or approved industrial zones, and under Article 23 of the Income Tax Law a wage exemption for qualified service centre personnel of up to three times the gross minimum wage, or five times inside the centre or approved zones. Communiqués No. 334 and Series No. 26 govern these in detail.
- What is a qualified service centre? A category defined by Law No. 7582 in the Foreign Direct Investment Law for capital companies that provide management and similar services to related parties operating in at least three countries. It may deduct ninety-five per cent of its qualifying foreign-source earnings, rising to one hundred per cent inside the Istanbul Finance Center or approved zones, for twenty accounting periods from the period it begins operating, provided the earnings are transferred to Turkey by the return deadline and shown separately on the return. It is the enacted vehicle closest to what the announcement called a regional headquarters incentive.
- How does the global minimum tax affect these incentives? Turkey enacted the local and global minimum complementary corporate tax through Law No. 7524 (Official Gazette 2 August 2024), targeting groups with consolidated revenue of 750 million euro or more at a fifteen per cent floor. For an in-scope group, a low Turkish effective rate produced by the package's deductions can be topped up to fifteen per cent. Groups below the threshold take the full benefit, and Communiqué Series No. 26 confirms that the new deductions are taken into account in the domestic minimum corporate tax computation.
- Was the One-Stop Office enacted? The broad investor-wide One-Stop Office described in April is a programme objective rather than a new statutory mechanism in Law No. 7582. A one-stop arrangement already exists within the Istanbul Finance Center under its own legislation, coordinated by the Presidency's Finance Office, but the wider office is not legislated in this statute.
- When do the different measures take effect? The statute entered into force on 4 June 2026 and the Communiqués on 4 July 2026. The income exemption reaches income from 1 January 2026 for those treated as resident, with the certificate deadline at the end of the year of residency or the following February. The wealth amnesty runs from 4 June 2026 to 31 July 2027. The transit trade and qualified service centre deductions apply to 2026-period earnings in returns from 1 July 2026. The production reduction applies from the 2027 tax period. The Istanbul Finance Center extension and the public-debt deferral changes took effect on publication of the statute.
- What documentation will I need? Each measure places the burden of proof on the taxpayer. The income exemption needs a complete and timely certificate petition supported by evidence of a clean three-year history; the wealth amnesty needs the bank's certified Annex 1 copy, the Annex 2 commitment, transfer and conversion receipts, customs documents for physical imports, and beneficial ownership evidence for assets held through others; the production reduction needs an industrial registry certificate and production records; the transit trade and qualified service centre deductions need evidence of offshore counterparties, timely repatriation, separate presentation on the return, and the centre's qualifying conditions. Foreign documents generally need apostille authentication and sworn translation.
- How does ER&GUN&ER Law Firm advise on the 2026 package? We work from all three layers, the statute, the Communiqués and the Revenue Administration guidance, identify the measures that fit a client's profile, confirm the statutory and procedural conditions, calendar the deadlines the Communiqués created, and build the documentary file each measure requires. For individuals that usually means the income exemption with its certificate, the one per cent inheritance rate, and the wealth amnesty together; for companies it means the qualified service centre or transit trade deduction and the production reduction, read against the global minimum tax. We coordinate the income, wealth, corporate, and immigration plans so they fit together.
