For US citizens and green-card holders in Turkey, US tax compliance involves navigating a US-Turkey income tax treaty and complex rules for local investments. While the treaty provides some relief, its saving clause means most Americans still have a full US filing obligation.
A critical point is the absence of a US-Turkey totalization agreement, which results in double social security taxation for self-employed individuals. Additionally, Turkish private pensions and mutual funds often trigger complex US reporting for foreign trusts and Passive Foreign Investment Companies (PFICs).
US filing basics every American abroad must know
US citizens and green-card holders are taxed on worldwide income wherever they live, and usually must file Form 1040 once gross income exceeds the IRS threshold ($15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household for 2025), even when no tax is ultimately due. The tools that reduce double taxation are the Foreign Earned Income Exclusion (FEIE, up to $130,000 for 2025 under IRC §911) and the Foreign Tax Credit. Neither is automatic. The FEIE requires a tax home in a foreign country plus either the bona fide residence test or 330 full days abroad in a 12-month period, and it reaches earned income only. The Foreign Tax Credit is figured separately for each income category under IRC §904 and is capped at the US tax on the foreign income in that category, so it reduces double taxation without guaranteeing that none remains.
Two reporting rules catch most filers in Turkey: the FBAR (FinCEN Form 114), required when foreign financial accounts exceed $10,000 in aggregate at any point in the year, and Form 8938 (FATCA) for specified foreign assets above the applicable threshold. Both can carry penalties even when no tax is owed. If you are behind, the Streamlined Filing Compliance Procedures are the usual path back for non-willful taxpayers. They run on two tracks: the foreign track carries no offshore penalty but requires meeting the program's non-residency test, and the domestic track carries a 5% offshore penalty but works through amended returns, so it does not fit someone who never filed at all. Tax and interest on the catch-up years are owed whichever route applies.
US tax treaty with Turkey
The US-Turkey income tax treaty aims to prevent the double taxation of income. However, for US citizens and residents, its direct benefits are limited by Article 1(3), the saving clause. This clause allows the US to tax its citizens on their worldwide income as if the treaty didn't exist.
In practice, the treaty is most useful for reducing withholding taxes on US-source income paid to Turkish residents, providing rules for determining tax residency, and preventing certain types of income from being taxed by both countries. For most Americans in Turkey, the primary mechanism for avoiding double taxation is not the treaty itself, but the US Foreign Tax Credit, which is claimed on Form 1116.
Article 1(3) (Saving Clause).
This is a standard clause in US tax treaties that reserves the right of the United States to tax its citizens and residents on their worldwide income, regardless of other provisions in the treaty. This is the fundamental reason why US citizens living in Turkey must still file a US tax return and report all their income.
Article 10 (Dividends).
This article limits the withholding tax that the source country can impose on dividends. The general limit is 20%, but it is reduced to 15% if the beneficial owner is a company that owns at least 10% of the voting stock of the dividend-paying company.
Article 11 (Interest).
This article caps the withholding tax on interest at 15%. A lower rate of 10% applies to interest derived from a loan of any kind granted by a financial institution such as a bank, savings institution, or insurance company. Interest paid to the other government or its central bank, and interest on a loan that government guarantees or insures, is exempt at source.
Article 12 (Royalties).
This article sets two rates. Royalties for the use of copyrights, patents, trademarks, designs, plans, secret formulas or processes, and know-how are capped at 10%. Royalties for the use of industrial, commercial, or scientific equipment are capped at 5%.
| Income type | Treaty rate | Statutory rate | Notes |
|---|---|---|---|
| Dividends | 20% | 30% | 15% where the beneficial owner is a company that owns at least 10% of the voting stock of the paying company. |
| Interest | 15% | 30% | 10% for interest from a loan granted by a financial institution. |
| Royalties | 10% | 30% | 5% for royalties for the use of industrial, commercial, or scientific equipment. |
Because of the saving clause, a US citizen living in Turkey generally cannot use the treaty to exempt their Turkish-source income from US tax. The treaty's main functions for a US citizen are to reduce withholding taxes on certain cross-border payments and to provide tie-breaker rules for residency disputes. The US Foreign Tax Credit remains the primary tool for mitigating double taxation.
Turkish Private Pensions (BES) and US Tax
Turkey's primary private retirement savings vehicle is the Private Pension System (Bireysel Emeklilik Sistemi or BES). For US tax purposes, a BES is not considered a 'qualified' retirement plan like a 401(k).
This has several important consequences:
- No US Deduction: Contributions you make to your BES are not deductible on your US tax return.
- Employer Contributions: Any contributions made by your employer to your BES are generally considered taxable compensation to you in the year they are made.
- Complex Reporting: A BES account is often treated as a foreign trust for US tax purposes, which can trigger a filing requirement for Form 3520 (Annual Return To Report Transactions With Foreign Trusts) and Form 3520-A (Annual Information Return of Foreign Trust With a U.S. Owner).
- PFIC Issues: The investments held within a BES are typically Turkish mutual funds, which are almost always classified as Passive Foreign Investment Companies (PFICs). This requires filing Form 8621 for each fund, and without specific tax elections, the growth and distributions can be subject to a very punitive US tax regime.
- FBAR and FATCA: Your BES account balance must be included when determining if you meet the filing thresholds for FinCEN Form 114 (FBAR) and Form 8938 (FATCA).
Investments, property, and capital gains in Turkey
Investing in Turkey as a US person requires careful attention to US anti-deferral tax regimes. Many common Turkish investments are treated very differently by the IRS than by Turkish tax authorities.
- Passive Foreign Investment Companies (PFICs): Any investment in a Turkish mutual fund, exchange-traded fund (ETF), or similar pooled investment vehicle is likely a PFIC. Owning PFICs requires filing Form 8621 for each one. The default tax treatment under Section 1291 is extremely harsh, involving high tax rates and interest charges on distributions and sales. Making a timely Qualified Electing Fund (QEF) or Mark-to-Market (MTM) election can provide better tax results, but requires specific information from the fund that can be difficult to obtain.
- Controlled Foreign Corporations (CFCs): A Turkish corporation is a CFC when US shareholders in aggregate own more than 50% of it by vote or by value, counting only those US shareholders who each own 10% or more. This triggers a requirement to file Form 5471, an extensive information return. As a shareholder in a CFC, you may be subject to current US tax on the company's earnings under the Global Intangible Low-Taxed Income (GILTI) or Subpart F income rules, even if you receive no dividends.
- Capital Gains on Property: While the tax treaty provides rules for taxing capital gains, the saving clause means the US continues to tax its citizens on worldwide capital gains. If you sell your Turkish home, for example, you must report the gain on your US tax return. The US has its own rules for a primary residence exclusion (Section 121), which may or may not apply, and they do not mirror any similar exemption in Turkish law.
Self-employment and companies in Turkey
This is one of the most significant and costly areas of US tax law for Americans in Turkey. The United States and Turkey do not have a Social Security Totalization Agreement in force. This has a major consequence for self-employed individuals.
If you are a self-employed US citizen or green-card holder living in Turkey, you are subject to social security systems in both countries. You must pay into the Turkish social security system as required by local law, and you must also pay US self-employment tax. That tax is 15.3% on 92.35% of your net earnings from self-employment, with the 12.4% Social Security portion stopping at the annual wage base ($176,100 for 2025, $184,500 for 2026) and the 2.9% Medicare portion uncapped, plus a further 0.9% Additional Medicare Tax on combined Medicare-taxed wages and self-employment income above $200,000 for a single, head-of-household or qualifying-surviving-spouse filer, $250,000 for a joint return, and $125,000 for married filing separately, and it applies once those net earnings are $400 or more.
It is not possible to obtain a Certificate of Coverage to claim an exemption from US self-employment tax. The Foreign Earned Income Exclusion (FEIE) can reduce your US income tax, but it does not reduce your net earnings from self-employment for the purpose of calculating US self-employment tax. This double contribution is a significant financial burden and a common point of confusion.
Worked examples
Salaried employee at a Turkish tech company (2025)
Sarah is a US citizen working as a project manager in Istanbul for a Turkish employer. Her annual salary is equivalent to USD 140,000. She has a local bank account with a balance of over $10,000 and a BES private pension account.
For her US tax return, Sarah can use the Foreign Earned Income Exclusion (FEIE) to exclude up to the 2025 limit ($130,000) of her salary from US income tax, provided she has a tax home in Turkey and meets either the bona fide residence test or the 330-day physical presence test. That would leave about $10,000 of her salary subject to US income tax, taxed under the section 911(f) stacking rule at the rates that would apply if the excluded amount were still counted. Alternatively, she could use the Foreign Tax Credit (FTC) to offset her US tax liability with the income taxes she pays in Turkey. Because Turkish tax rates are relatively high, the FTC would likely eliminate her US income tax on the salary as well.
Regardless of her income tax, she must file an FBAR (FinCEN Form 114) to report her Turkish bank and BES accounts. She may also need to file Form 8938 if her foreign asset values exceed the threshold. The investments in her BES are likely PFICs, which technically require her to file Form 8621.
Self-employed graphic designer (2025)
John is a US citizen living in Antalya and working as a freelance graphic designer for clients in Europe and the US. His net self-employment income for the year is $90,000. He pays into the Turkish social security system (Bağ-Kur) as required for self-employed individuals in Turkey.
Because there is no US-Turkey totalization agreement, John is also liable for US self-employment tax. If he has a tax home in Turkey and meets either the bona fide residence test or the 330-day physical presence test, he can use the FEIE to exclude the $90,000 from US income tax, leaving little or no income tax. The FEIE does not touch self-employment tax.
His US self-employment tax calculation is:
- Net Earnings: $90,000
- Base for SE Tax: $90,000 * 0.9235 = $83,115
- That base is below the 2025 Social Security wage base of $176,100, so the full 15.3% applies. Above that base only the 2.9% Medicare portion continues.
- SE Tax Owed: $83,115 * 15.3% = $12,716.60
John must pay this $12,716.60 to the IRS, in addition to his mandatory contributions to the Turkish system. This is a direct and unavoidable consequence of the lack of a totalization agreement.
Retiree with US and Turkish assets (2025)
Linda is a US citizen retired in Fethiye. She receives a $60,000 annual pension from her former US employer and $15,000 in US Social Security benefits. She also has a Turkish BES account valued at $250,000 and a local bank account with $50,000.
Her US pension and a portion of her US Social Security are taxable in the United States. The US-Turkey tax treaty does not prevent the US from taxing the pension of its citizen.
Her primary US compliance burden relates to her Turkish assets. The combined value of her BES and bank account ($300,000) requires her to file both an FBAR and Form 8938. The BES account itself is likely considered a foreign trust (requiring Form 3520/3520-A) and holds PFICs (requiring Form 8621). Any distributions she takes from the BES, or even internal earnings depending on her tax elections, could be taxable in the US. She should consult a tax professional to manage the complex reporting for her BES to avoid significant penalties.
Common mistakes for Americans in Turkey
- Forgetting that there is NO US-Turkey totalization agreement and failing to pay US self-employment tax.
- Incorrectly believing the Foreign Earned Income Exclusion (FEIE) eliminates the need to pay US self-employment tax.
- Failing to report a Turkish private pension (BES) on an FBAR (FinCEN Form 114) and, if applicable, Form 8938.
- Ignoring the complex PFIC rules (Form 8621) for investments inside a BES or for Turkish mutual funds, leading to punitive tax outcomes.
- Assuming a Turkish company you own is not a Controlled Foreign Corporation (CFC) and failing to file the required Form 5471.
- Thinking that contributions to a BES are tax-deductible on a US return, which they are not.
- Believing the US-Turkey tax treaty allows a US citizen to be exempt from filing a US tax return due to the saving clause.
- Assuming the sale of a primary residence in Turkey is automatically tax-free in the US without checking the specific rules of US Code Section 121.
Turkey tax FAQ
As a self-employed American in Turkey, do I have to pay US Social Security taxes?
Yes. There is no Social Security Totalization Agreement between the US and Turkey. US self-employment tax is 15.3% on 92.35% of your net earnings from self-employment, with the 12.4% Social Security portion stopping at the annual wage base ($176,100 for 2025) and the 2.9% Medicare portion uncapped, and it applies once those net earnings are $400 or more. It is owed in addition to any mandatory social security contributions you make in Turkey. You cannot get a Certificate of Coverage to avoid this, the Foreign Earned Income Exclusion does not reduce it, and the Foreign Tax Credit cannot offset it.
Is my Turkish private pension (BES) reported on my US taxes?
Yes, in several ways. The account value must be reported on your FBAR (FinCEN Form 114) and likely Form 8938. Because the BES is not a 'qualified' plan, contributions are not US-tax-deductible, and employer contributions are often currently taxable. The underlying investments are usually PFICs, requiring Form 8621, and the account itself may be treated as a foreign trust, requiring Forms 3520/3520-A.
Does the US-Turkey tax treaty eliminate my US tax filing obligation?
No. The treaty contains a 'saving clause' that allows the US to continue taxing its citizens as if the treaty did not exist. All US citizens and green-card holders who meet the filing thresholds must file a US tax return and report their worldwide income, regardless of where they live.
Do I need to report my Turkish bank account to the US government?
Yes, if the total value of all your foreign financial accounts (including bank, brokerage, and pension accounts like the BES) exceeds $10,000 at any point during the year, you must file a FinCEN Form 114, Report of Foreign Bank and Financial Accounts (FBAR). Higher asset thresholds may also require you to file Form 8938 with your tax return.
What is a PFIC and why does it matter for my investments in Turkey?
A PFIC is a Passive Foreign Investment Company. This US tax classification applies to most foreign mutual funds and many other pooled investments. If you own Turkish mutual funds, either directly or through a pension like the BES, they are almost certainly PFICs. This requires filing Form 8621 and can result in very high US taxes unless you make specific, timely elections.
I own a Turkish limited company (Ltd. Şti.). What are my US reporting duties?
The company is a Controlled Foreign Corporation (CFC) when US shareholders in aggregate own more than 50% of it by vote or by value, counting only those US shareholders who each own 10% or more. It is the aggregate that decides it, not any one holder's stake. If it is a CFC and you are one of those 10% shareholders, you file Form 5471 annually. This is a complex information return, and owning a CFC could also mean you have to pay current US tax on the company's profits under the GILTI rules, even if you don't take a distribution.
Can I use the Foreign Tax Credit for taxes I pay in Turkey?
Yes. The Foreign Tax Credit is the main tool for relieving double taxation. You claim it on Form 1116 for income taxes paid to Turkey. It is not unlimited: under section 904 the credit is computed separately for each income category (general, passive, and others), and within each category it is capped at the US tax on your foreign-source income in that category. Excess credits carry back one year and forward ten, but they cannot cross categories, and the credit cannot offset self-employment tax at all. Because Turkish income tax rates are generally comparable to or higher than US rates, the credit often reduces the US tax on Turkish earnings to zero, but that is an outcome to be computed, not assumed.
What are the US tax treaty withholding rates for income paid from the US to a resident of Turkey?
The treaty sets maximum withholding rates on US-source income paid to a Turkish resident. The general rates are 20% for dividends (with a 15% rate for certain corporate owners), 15% for interest (with a 10% rate for loans from financial institutions), and 10% for royalties.
