Overseas Property Income Tax & Turkey’s Double Tax Treaties

Turkish investors buying property abroad must navigate foreign withholding taxes and double‑taxation treaties to avoid paying twice on rental income.

Why Turkish Investors Need to Mind Overseas Property Tax

Buying an apartment in Athens, a villa on the Costa del Sol or a condo in Bangkok can be an attractive way to diversify wealth. However, rental income generated abroad does not disappear into a tax‑free void. For Turkish citizens, both the source country’s withholding rules and Turkey’s own taxation framework apply, unless a double‑taxation treaty (DTA) reduces the burden.

Turkey’s Worldwide Taxation Rules

Turkey taxes its residents on worldwide income. A person is considered a tax resident if they stay in Turkey for more than 183 days in a calendar year, have their centre of vital interests in Turkey, or are registered as a Turkish domicile. Residents must declare all foreign rental earnings on the annual Turkish tax return (Beyanname). Non‑residents are taxed only on income sourced within Turkey.

When a resident earns rent abroad, two taxes can arise:

Source‑country withholding tax – deducted at the point of payment by the tenant or local tax authority.
Turkish income tax – calculated on the net amount after foreign tax credit, if a DTA exists.

The key to avoiding double taxation is the credit mechanism built into most DTAs that Turkey has signed with over 30 jurisdictions.

Double Taxation Treaties – The Safety Net

A DTA is a bilateral agreement that allocates taxing rights between two states. For rental income, the treaty typically allows the country where the property is located to levy a limited withholding tax, while granting Turkey the right to tax the same income and then provide a credit for the foreign tax already paid.

How a DTA Works in Practice

Assume a Turkish resident rents a flat in Greece and receives €10,000 gross. Greek law imposes a 15% withholding tax, so €1,500 is deducted at source. Under the Turkey‑Greece DTA, the maximum withholding may be reduced to 7% (subject to proof of residency). The investor reports the €10,000 on their Turkish return, claims a credit for the €750 actually paid, and pays the remaining Turkish tax based on the progressive rates (15%‑40%). If the Turkish liability exceeds the foreign tax, the difference is payable; if it is lower, no refund is granted.

Because treaty terms differ, investors should verify the exact ceiling for each country. In many cases the cap lies between 5 % and 10 % of gross rental income.

Key Countries: Property Thresholds, Rental Taxes and Treaty Caps

Country	Residency/ Citizenship Route	Typical Source‑Country Withholding Tax on Rent	DTA Maximum (if applicable)	Airbnb / Short‑Term Rental Rules
Greece	Golden Visa – €250k, €400k or €800k property; 5‑year renewable EU residence	15 % (gross)	Usually limited to 7 %	Banned on units obtained through the Golden Visa programme
Montenegro	Property‑based residence – purchase in euros, renewable; CBI closed 2022	10 % (gross)	Up to 5 %	No specific Airbnb restriction, but local zoning may apply
Spain	Golden Visa abolished April 2025; now non‑lucrative or digital‑nomad visas for residence	19 % (gross)	Reduced to 10 % under the Turkey‑Spain DTA	Short‑term rentals allowed, subject to regional licensing
Portugal	D7 visa – passive income; residential property removed from Golden Visa Oct 2023	28 % (gross)	Limited to 10 % under the Turkey‑Portugal DTA	Airbnb permitted, but municipalities impose caps on days per year
Thailand	No residency‑by‑property; condos freehold (49 % foreign ownership limit)	15 % withholding on gross rent for non‑residents	Turkey‑Thailand DTA caps at 10 %	Short‑term rentals allowed in many condo projects, but building bylaws vary

Practical Steps for Turkish Buyers

Confirm your tax residency status. If you spend more than 183 days in Turkey, you will be liable for worldwide income.
Identify the DTA that applies. Check whether Turkey has a treaty with the country where you intend to buy. The Ministry of Finance website provides an up‑to‑date list.
Structure the purchase. Use a local legal entity (e.g., a limited company) only if it offers tax advantages and complies with anti‑money‑laundering rules.
Collect proof of Turkish residence. A certificate of residence (ikametgah) is required to claim treaty benefits at the source country’s tax office.
Pay foreign withholding tax correctly. Provide the landlord or local tax authority with your Turkish tax‑identification number (TIN) and a copy of the residency certificate.
- If the withheld amount exceeds the treaty cap, file for a refund in the source country.
Declare the income on your Turkish tax return. Report gross rental earnings, deduct allowable expenses (maintenance, management fees, depreciation), and claim the foreign‑tax credit.
- Keep all invoices, bank statements and the foreign withholding certificate for at least five years.
Plan cash flow. Remember that Turkish tax is payable in two installments (May and November). Budget for any additional VAT or municipal taxes that may arise in the source country.

Residency Options vs. Tax Implications

Many investors are attracted by residency programmes that also open doors to Schengen travel, education benefits or a pathway to citizenship. While these schemes do not directly change the tax treatment of rental income, they can affect your overall tax domicile.

Greece’s Golden Visa grants EU residence but does not automatically shift tax residency; you remain Turkish‑taxed unless you spend >183 days in Greece.
Montenegro’s property‑based residence is non‑EU, so it rarely influences Turkish tax status, yet the DTA with Turkey limits withholding to 5 %.
Spain and Portugal now rely on non‑lucrative or passive‑income visas. Holding a visa does not create tax residency unless you meet the physical‑presence test.
Thailand offers no residency‑by‑investment, so Turkish tax treatment stays unchanged.
Resida Global can help you navigate both the property purchase and the accompanying residence permit, ensuring that all paperwork aligns with tax requirements.

Common Pitfalls to Avoid

Assuming a DTA eliminates all foreign tax. The treaty only caps the withholding; you still owe Turkish tax on net income.
Neglecting local rental regulations. In Greece, Airbnb is prohibited for Golden Visa units, which can dramatically affect projected yields.
Using personal names instead of a corporate structure when advantageous. Certain jurisdictions allow depreciation deductions only to companies.
Missing the residency‑certificate deadline. Most source countries require proof within 30 days of rent receipt; otherwise the standard rate applies.
Forgetting currency conversion rules. Turkish tax law requires reporting foreign income in TRY using the official exchange rate on the day of receipt.

Conclusion

Turkish investors can profit from overseas property without paying tax twice, provided they understand Turkey’s worldwide taxation principle, leverage the relevant double‑taxation treaty, and comply with local withholding rules. By following a clear step‑by‑step process—confirming residency status, securing treaty benefits, filing accurate returns, and respecting each country’s rental regulations—investors safeguard their cash flow and stay on the right side of the law. When in doubt, professional advice from tax specialists or agencies such as Resida Global can make the difference between a smooth investment and an unexpected tax bill.

Frequently Asked Questions

Do Turkish citizens have to pay Turkish tax on rental income earned abroad?

Yes, if they are tax residents of Turkey (generally more than 183 days per year). Worldwide income, including foreign rent, must be declared and taxed after crediting any foreign withholding tax under a DTA.

Can the double‑taxation treaty reduce the source‑country withholding tax?

In most cases the treaty sets a maximum rate—often between 5 % and 10 % of gross rent—lower than the domestic withholding rate. Proof of Turkish residency is required to benefit.

Is Airbnb allowed on Greek Golden Visa properties?

No. The Greek government prohibits short‑term rentals such as Airbnb on units purchased through the Golden Visa programme, which can affect expected rental yields.

What happens to Turkish tax residency if I obtain a residence permit in Spain or Portugal?

Obtaining a visa does not automatically change your tax domicile. You remain a Turkish tax resident unless you spend more than 183 days per year in the new country.

Do I need a local entity to buy property in Thailand?

Thailand only allows foreign ownership of condominium units up to 49 % of the building. Land cannot be owned directly, and residency is not granted by property purchase; a local company can be used for management but does not affect tax treatment.
