US-Turkey Tax Treaty 2026: Practical Guide for Individuals and Businesses

The United States and Turkey have an income tax treaty (the "Treaty") that has been in force since 1998. The Treaty provides important protections against double taxation and reduced withholding tax rates for qualifying individuals and businesses. However, the Treaty has significant limitations, and many Turkish individuals and businesses fail to claim available benefits — or incorrectly claim benefits they are not entitled to.

The US-Turkey Income Tax Treaty covers:

• Reduced withholding tax rates on dividends, interest, and royalties
• Permanent establishment rules that determine when a Turkish business is subject to US tax
• Residency tie-breaker rules for individuals who might otherwise be taxable in both countries
• Exemptions for certain categories of income
• Exchange of information between US and Turkish tax authorities

Important limitation: The Treaty does not eliminate US taxation for Turkish nationals who become US tax residents (green card holders or substantial presence test). Once a Turkish national becomes a US tax resident, they are subject to US tax on worldwide income regardless of the Treaty.

One of the Treaty's most important benefits is reduced withholding tax rates on payments from the US to Turkey:

To claim reduced withholding rates, Turkish recipients must:

1. Provide the US payer with Form W-8BEN (individuals) or Form W-8BEN-E (entities)
2. Claim the applicable treaty article on the W-8 form
3. Certify that they are residents of Turkey for treaty purposes

US payers who fail to obtain proper W-8 documentation must withhold at the 30% domestic rate.

The Treaty's permanent establishment (PE) provisions determine when a Turkish business's US activities create a taxable presence in the US.

A Turkish company has a US PE if it has:

• A fixed place of business in the US (office, factory, workshop, etc.)
• A construction or installation project lasting more than 12 months
• A dependent agent in the US who habitually concludes contracts on the company's behalf

• A US office used solely for purchasing goods
• A US office used solely for storing, displaying, or delivering goods
• A US office used solely for collecting information
• A US agent who acts in an independent capacity

If a Turkish company has a US PE, the profits attributable to the PE are subject to US federal income tax (and potentially state income tax). Without a PE, a Turkish company's US-source business profits are generally not subject to US tax.

Turkish nationals who spend significant time in the US may become US tax residents under the substantial presence test (183 days in a 3-year weighted formula). If a Turkish national is a tax resident of both the US and Turkey, the Treaty's tie-breaker rule determines which country has primary taxing rights.

The tie-breaker applies the following tests in order:

1. Permanent home: Where does the individual have a permanent home available?
2. Center of vital interests: Where are the individual's personal and economic relations closer?
3. Habitual abode: Where does the individual habitually reside?
4. Nationality: Of which country is the individual a national?
5. Mutual agreement: If none of the above resolves the issue, the competent authorities determine residency by mutual agreement

Turkish nationals claiming treaty residency to avoid US taxation must file Form 8833 (Treaty-Based Return Position Disclosure) with their US tax return.

Under the Treaty, business profits of a Turkish enterprise are taxable in the US only to the extent attributable to a US PE. This is a significant protection for Turkish companies that conduct limited US activities without establishing a PE.

The Treaty includes a Limitation on Benefits (LOB) article that prevents "treaty shopping" — using the Treaty by entities that are not genuine Turkish residents. To qualify for Treaty benefits, a Turkish entity must satisfy one of the LOB tests:

• Individual test (owned by Turkish nationals)
• Publicly traded company test
• Active trade or business test
• Other qualifying tests

Turkish holding companies or special purpose vehicles may not qualify for Treaty benefits if they fail the LOB tests.

The US and Turkey do not have an estate and gift tax treaty. Turkish nationals who own US assets are subject to US estate tax with only a $60,000 exemption.

The US and Turkey do not have a totalization agreement. Turkish nationals working in the US may be subject to both US Social Security taxes and Turkish social security contributions on the same earnings.

US state income taxes are not covered by the Treaty. Turkish individuals and businesses with US state tax obligations cannot claim Treaty benefits to reduce state taxes.

• File Form W-8BEN with US payers to claim reduced withholding rates
• Consider treaty residency position if subject to US substantial presence test
• File Form 8833 when claiming treaty benefits on a US tax return
• Consult with both US and Turkish tax advisors to ensure consistent treaty positions

• Analyze whether US activities create a PE
• Structure US activities to avoid PE where possible
• Claim reduced withholding rates on US-source income
• Ensure LOB requirements are satisfied before claiming Treaty benefits

• Obtain Form W-8BEN or W-8BEN-E from Turkish recipients
• Apply correct Treaty withholding rates
• File Form 1042 and 1042-S to report Treaty-reduced withholding
