Rental Income in Turkey: Rental Property Investment 2026

If you own a rental property in Turkey, the purchase and the lease are only half the story — the Turkish tax authority (Gelir İdaresi Başkanlığı, GİB) expects you to declare that income every year, whether you live in Istanbul or on the other side of the world. This guide focuses specifically on the tax and compliance side of rental income you are already earning: how it is classified, what you can deduct, when withholding applies, and how foreign landlords typically avoid being taxed twice. If you are still deciding whether and where to buy a rental property, see our ROI guide for rental property investment instead, and if you want a picture of pricing and demand nationwide, see our rental market overview.

Key Takeaways

• Rental income in Turkey is taxed as Gayrimenkul Sermaye İradı (GMSİ) — capital income from immovable property — under the personal income tax law, and applies equally to resident and non-resident owners.
• For 2025 residential rental income (declared in March 2026), a TL 47,000 exemption applied before tax is calculated, unless disqualifying conditions applied. This figure is adjusted annually — always confirm the current year's number.
• You choose between the lump-sum expense method (a flat 15% deduction, no receipts) and the real expense method (actual documented costs) — switching back from lump-sum requires waiting two years.
• Commercial tenants who are companies must withhold 20% of the rent at source and pay it to the tax office; this withheld amount is credited against your annual tax.
• Non-resident owners still file an annual declaration, generally by end of March for the prior year, usually through a Turkish accountant or tax representative.
• Double taxation treaties with 80+ countries generally prevent being taxed twice on the same rental income, but the relief mechanism (exemption vs. credit) varies by treaty — verify yours.

How Rental Income Is Classified and Taxed

Under Turkish income tax law, rent from a house, apartment, shop, office or land is not treated like salary or business profit — it falls under its own category, GMSİ, taxed via Turkey's progressive personal income tax brackets after allowable deductions. The brackets and thresholds are revised annually for inflation, so a bracket table from an earlier year is not reliable — get the current-year brackets from GİB or your accountant before estimating your bill.

Two separate regimes matter depending on who your tenant is:

Scenario	How it works
Residential lease to an individual	No withholding; you declare the full rent yourself, minus the exemption and expense deduction, by the following March
Commercial lease to a company/legal entity	Tenant withholds 20% at source (stopaj) and pays it to the tax office; you still generally file, and the withheld amount is credited
Residential lease, income above the exemption	Exemption applies only to the residential (housing) portion of GMSİ, subject to the high-income disqualifier
Non-resident owner	Same GMSİ rules apply to Turkey-source income; filing is usually done via a tax representative or accountant

Step by Step: How the Annual Declaration Works

Step 1 — Get a Turkish tax number

A vergi kimlik numarası is required to file, receive rent legally through a Turkish bank, and register a lease. Foreign owners typically obtain this when they buy the property or open a Turkish bank account.

Step 2 — Track your gross rental income for the calendar year

Total the rent actually received in the calendar year (not invoiced or accrued) from all Turkish properties you own. Bank records are the standard evidence — cash rent paid outside the banking system is both harder to prove and increasingly scrutinized.

Step 3 — Apply the residential exemption, if eligible

If the lease is residential and your qualifying income does not exceed the disqualifying threshold, subtract the year's exemption amount from your gross residential rent before calculating tax. This exemption does not apply to commercial rental income.

Step 4 — Choose your expense method

• Lump-sum (götürü) method: deduct a flat 15% of the remaining income after the exemption. Simple, no documentation, but you cannot switch to the real method for two years if you pick this one.
• Real (gerçek) expense method: deduct actual, documented costs — property tax (emlak vergisi), building management dues (aidat), repairs and maintenance, fire/DASK insurance, mortgage interest, property management or agent commission, and depreciation. This usually wins if you financed the purchase or did significant renovation work.

Calculate your tax under both methods before choosing — the difference can be material.

Step 5 — Credit any withholding already paid

If a commercial tenant withheld 20% during the year, that amount reduces the tax due on your final declaration rather than being an extra cost on top.

Step 6 — File by the deadline

Declarations for a given year's rental income are generally due by the end of March the following year, filed through GİB's e-beyanname system or, for non-residents without e-signature access, through an accountant or authorized representative holding a power of attorney.

Step 7 — Pay in one or two installments

Turkey typically allows the resulting tax to be paid in two installments (spring and summer) rather than a single lump sum — useful for cash-flow planning if you are also servicing a mortgage.

Deductible Expenses Under the Real Method

Expense category	Typically deductible?
Property tax (emlak vergisi)	Yes
Building maintenance dues (aidat)	Yes
Repairs and maintenance	Yes, with invoices
Fire/earthquake insurance (DASK) and building insurance	Yes
Mortgage/loan interest on the property	Yes
Property management or letting agent commission	Yes
Depreciation (amortisman)	Yes, on the building portion of the purchase cost
Travel costs to visit the property	Generally no, unless directly and demonstrably tied to management of the let

Keep every invoice in your own name — expenses without proper documentation are disallowed if the real method is chosen and the file is later reviewed.

Foreign Landlords and Double Taxation

Because Turkey taxes rental income at source regardless of where the owner lives, the practical question for most FTurkey clients is not "do I owe Turkish tax" but "do I also owe tax at home on the same income, and if so, does anything offset it." Turkey has double taxation agreements with more than 80 countries, and most follow the international norm that income from immovable property is taxable primarily where the property sits — Turkey, in this case. Your home country then typically either exempts that income (with progression) or grants a credit for the Turkish tax paid, but the exact mechanism, forms and reporting obligations differ treaty by treaty. This is not a step to guess at: bring your Turkish tax certificate to a cross-border tax advisor in your home country, or use our tax consulting and planning service, which coordinates both sides.

Common Mistakes Foreign Landlords Make

1. Assuming no Turkish tax number means no obligation. The obligation attaches to the income, not to your residency status — non-residents must still declare.
2. Missing the March deadline because no one reminded them from abroad. Set your own annual calendar reminder or retain an accountant on a standing basis.
3. Choosing the lump-sum method by default without comparing it to real expenses, especially after a year with a large repair bill or full mortgage interest.
4. Accepting cash rent to "simplify" things — this weakens your evidence trail and can trigger closer scrutiny, without actually reducing your legal liability.
5. Ignoring the commercial-lease withholding rules and being surprised when a company tenant pays 20% less than the contract rent — that 20% was never yours to begin with; it was pre-paid tax.
6. Not checking the DTA with their home country, and either paying tax twice or under-reporting at home by assuming Turkey "covers it."

Rental Income Tax vs. the Bigger Picture

Declaring and optimizing your annual GMSİ tax is one piece of owning rental property in Turkey. If you are still choosing a city or property type to maximize yield, our ROI guide walks through gross vs. net yield calculations. If you want to understand where Turkish rents are heading city by city before you buy or renew a lease, see our rental market overview. And if you are weighing whether qualifying property purchases could also support a residence permit or citizenship via real estate, those thresholds (USD 200,000 and USD 400,000 respectively) are entirely separate from the rental income tax rules covered here.

How FTurkey Helps

FTurkey works with licensed Turkish accountants (mali müşavir) who handle the full annual cycle for foreign landlords: obtaining your tax number, choosing the more favorable expense method each year, preparing and filing the GMSİ declaration, reconciling any withholding already paid, and coordinating with your home-country advisor on double-taxation relief. Explore our tax consulting and planning and tax advisory services, or contact us before your next March deadline so nothing is filed at the last minute.

This article is general information, not tax or legal advice. Turkish tax thresholds, rates and exemption amounts (including the residential rental exemption) are revalued annually and can change by regulation — confirm the figures in force for the relevant tax year with a licensed Turkish accountant or the Revenue Administration (GİB) before filing.
