The short answer: worldwide taxation, a 1986 treaty and a brand-new arrivals regime
Turkey is not a territorial or zero-tax jurisdiction. Residents are taxed on worldwide income at 15% to 40%, with brackets revised every year to chase inflation. What makes the corridor attractive in 2026/27 is new: Law No. 7582 introduced a 20-year exemption on foreign-source income and gains for qualifying new residents, on top of a treaty that already pushes taxing rights over UK private pensions to Turkey. Structured properly, a UK retirement here can carry a very light bill on both sides.
The deciding factor for your UK bill is not your Turkish residence permit or your villa in Bodrum. It is the UK Statutory Residence Test (HMRC manual RFIG20000), which decides, year by year, whether the UK can still tax your worldwide income. Three things have to line up: breaking UK residence under the SRT, claiming split-year treatment where you leave mid-year, and dealing properly with what stays UK-taxable regardless. Get those right and the Turkish position takes over.
Breaking UK residence: the Statutory Residence Test
The SRT is applied in order: the automatic overseas tests (which make you non-resident), then the automatic UK tests, then the sufficient ties test if neither is conclusive. For someone moving to Turkey to work, the third automatic overseas test is the target: full-time work abroad across the tax year, broadly an average of at least 35 hours a week with no significant breaks, fewer than 91 days in the UK and no more than 30 UK workdays.
Retirees, who make up a large share of this corridor, cannot use the full-time work route, so most rely on the sufficient ties test. That combines your UK day count with the ties you keep: family, available accommodation, substantive UK work, a 90-day prior-presence tie and, for recent leavers, a country tie. The more ties, the fewer UK days you are allowed; a recent leaver with three ties can be UK resident on as few as 46 days, and a kept UK home plus grandchildren visits is exactly how Antalya retirements fail in year one. Model your position with our SRT calculator and keep a day count from the start.
Split year, the P85 and your final tax return
Most people do not emigrate neatly on 6 April. Where the conditions are met, split-year treatment divides the tax year into a UK part (taxed on worldwide income) and an overseas part (taxed only on UK-source income), so income arising in Turkey after the split date is outside UK income tax for that year. The common gateways for leavers are starting full-time work overseas and ceasing to have a UK home.
The admin is the same as for any departure. File a P85 if you are leaving PAYE employment or a pension and will not file a return, because it triggers any in-year refund; skip it if you are sending a Self Assessment return for the year you leave. Split year is claimed on the SA109 residence pages, which cannot be filed through HMRC's own free online service, so you will generally need commercial software or an agent. Keep records of travel dates, work patterns and your Turkish accommodation: residence questions are evidenced after the fact.
What the UK keeps taxing after you go
Becoming non-resident does not switch off UK tax on UK-source income. Because Turkey taxes residents on worldwide income, some of it also enters the Turkish net, with the treaty deciding who has first claim and the new arrivals exemption potentially taking Turkey out of the picture for 20 years.
| Income or gain | UK position after you leave | Turkey position as a Turkish tax resident |
|---|---|---|
| UK rental profits on a kept property | UK-taxable; [Non-Resident Landlord Scheme](/guides/non-resident-landlord-tax) withholding at the basic rate unless HMRC approves gross payment | Foreign-source income, in the Turkish net with credit for UK tax, unless the 20-year new-resident exemption applies |
| Gains on UK property | NRCGT: report and pay within [60 days](/guides/cgt-60-day-reporting-non-residents) of completion, even where no tax is due; 18% or 24% after the £3,000 annual exempt amount | Foreign-source gain; under the treaty the UK may tax it, with the Turkish side depending on the new-resident exemption |
| UK government service pensions | Generally remain UK-taxable under Article 19 of the treaty | Outside Turkish tax unless you are both resident in and a national of Turkey |
| UK private and workplace pensions | Article 18 gives Turkey sole taxing rights, so UK tax can be removed by a treaty claim to HMRC | Worldwide income of a resident, unless the new-resident exemption covers it (confirm locally) |
| UK dividends and interest | Position depends on the treaty and the disregarded-income rules; take advice | Foreign dividends are taxable above a small annual threshold, unless the new-resident exemption applies |
| Worldwide estate on death | [Residence-based IHT](/guides/residence-based-iht) tail of up to 10 years for long-term UK residents | Turkish inheritance tax at 1% to 10% (gifts 10% to 30%), reduced to 1% inside the new-resident regime |
Two further UK rules deserve their own line. Since 6 April 2025 inheritance tax has been residence-based: if you were UK resident for at least 10 of the previous 20 tax years, your worldwide estate stays within UK IHT for up to 10 years after you leave, whatever the Turkish rates say. And most leavers should apply on form CF83 to keep paying voluntary National Insurance, because a full UK State Pension is cheap to protect and expensive to rebuild.
Turkish residence and rates, verified
You become Turkish tax resident in two main ways: your legal residence (your settled home, or an intention to settle) is in Turkey, or you are present there for more than six months in a calendar year, counted continuously including temporary absences. Foreigners in Turkey for a specific and temporary assignment, or for holiday, health care or education, are not treated as resident even beyond six months. Once resident, you are taxed on worldwide income; non-residents on Turkish-source income only.
Income tax is progressive and the brackets reset annually. For 2026, employment income is taxed at 15% up to TRY 190,000, 20% to TRY 400,000, 27% to TRY 1,500,000, 35% to TRY 5,300,000 and 40% above that (PwC Worldwide Tax Summaries: Turkey); non-employment income uses the same rates with different middle bands. Residential rental income below TRY 58,000 (2026) is exempt. Half of the gross dividends from Turkish resident companies are exempt, with a 15% dividend withholding tax, and many financial instruments are taxed by withholding at 0% to 20% rather than through the bands.
The honest boundary: Horizon advises on the UK side and coordinates with a local adviser in Turkey for Turkish filings, residence permits and the detail of the regimes below. The Turkish figures here are verified against current professional summaries, but lira thresholds move every year and your own Turkish registrations belong with local counsel.
The new 20-year foreign income exemption
Law No. 7582, published in Turkey's Official Gazette on 4 June 2026, created something this corridor has never had: a long-term inbound regime. Individuals who become Turkish tax resident on or after 1 January 2026, after three calendar years with no residence or tax liability in Turkey, are exempt from Turkish tax on foreign-source income and gains for 20 years, with no Turkish declaration required for the exempt income. Inheritance transfers during the eligibility period attract a reduced 1% rate, and a separate asset repatriation window runs until 31 July 2027 at rates from 0% to 5%.
For a UK leaver this is potentially transformative: UK pensions, dividends, interest and gains on non-Turkish assets are all foreign-source from a Turkish perspective. But the regime is new, secondary guidance is still bedding in, and how it interacts with each income type, and with treaty claims on the UK side, needs confirming with a Turkish adviser before you build a retirement on it. Treat it as a strong reason to get the sequencing right, not a substitute for advice on either side.
The UK-Turkey treaty and the pension answer
A full double taxation agreement exists. It was signed in London on 19 February 1986, entered into force on 26 October 1988 and has had effect in the UK since 6 April 1989 for income tax and capital gains tax, and in Turkey since 1 January 1989 (GOV.UK). It is an old treaty, but it works, and its pension article is the most important sentence in this corridor.
Article 18 provides that pensions and other similar remuneration paid in consideration of past employment to a resident of a contracting state are taxable only in the state of residence. Once you are treaty-resident in Turkey, your UK personal and workplace pensions fall out of UK tax, and a treaty relief claim to HMRC can have them paid without UK deduction. Article 19 is the exception: government service pensions generally stay taxable in the UK unless you are both a resident and a national of Turkey. Article 18 also covers payments under the social security scheme, which points the same way for the State Pension, and annuities as defined in the article, though each needs checking against your own facts. Article 6 keeps UK rental income taxable in the UK, and Article 13 does the same for gains on UK property. Treaty claims are made on the SA109, so keep the paperwork tidy from year one.
Antalya, Fethiye, Bodrum: buying property and the lira problem
The retirement corridors cluster on the coast: Antalya and its satellites, Fethiye and the Oludeniz strip, and the Bodrum peninsula. Buying is straightforward by international standards. The title deed transfer fee is 4% of the value, split equally between buyer and seller by law though often negotiated, and the annual property tax on dwellings is 0.1% of assessed value, doubled inside larger metropolitan municipalities, which covers most of the coast. High-value residences above an annually revalued threshold attract an additional valuable housing tax at 0.3% to 1%, although no charge arises where you own only one qualifying home.
Selling is where the two systems diverge. Turkey exempts an individual's gain entirely once the property has been held for more than five years; inside five years the gain is taxable at progressive rates, but the acquisition cost is indexed for producer price inflation in qualifying cases, which in a high-inflation economy strips most of the paper gain out of charge. The UK does the opposite: capital gains are computed in sterling, converting cost and proceeds at the exchange rates on the days you bought and sold, with no indexation at all. A flat that only kept pace with Turkish inflation can show a large sterling gain, or a loss, purely on currency movements, which matters if you sell while still UK resident or realise the gain abroad and return within five years.
Temporary non-residence: the five-year rule
If you were UK resident in at least four of the seven tax years before you left and you return within five years, the temporary non-residence rules tax gains and certain income realised while abroad in your year of return. The classic Turkish version of the trap is the retiree who sells the coast property, or draws a pension lump sum, in year three and then comes home to be nearer family: timed on the wrong side of the five-year line, the UK claws the lot back into charge. If there is any realistic chance of returning, plan disposals around the five-year anniversary, not around the Turkish exemptions.
