Tax Residency and Double Taxation in Turkey: “Will I Pay Tax on My Worldwide Income?”
If you are a digital nomad, long-stay visitor or retiree in Turkey, the key question is simple: once you become a Turkish tax resident, you are generally taxed on your worldwide income – unless a double tax treaty says otherwise.
Below is a practical overview for foreigners who spend long periods in Turkey or earn income from abroad.
1. When do you become a Turkish tax resident? (183-day rule)
Under Turkish income tax rules, an individual is treated as a full taxpayer (tax resident) if:
- their legal residence is in Turkey, or
- they stay in Turkey for more than six months (183 days) in a calendar year, even with breaks.
Full taxpayers are liable for worldwide income. Non-residents (limited taxpayers) are taxed only on Turkey-sourced income (for example, rent from a Turkish flat, a Turkish salary or business income in Turkey).
Important nuances:
- Your residence permit type (tourist, student, work) does not automatically decide tax residency; what matters is where you actually live and your intention to settle.
- There are limited exceptions (e.g. people staying temporarily for education or medical treatment), but most long-term digital nomads do not fall into these exceptions.
If you cross the 183-day threshold and your centre of life looks like Turkey, the Turkish tax office can treat you as resident even if you still consider yourself “based” elsewhere.
2. Double Tax Treaties: Can you avoid being taxed twice?
Turkey has double taxation avoidance agreements (DTAAs) with more than 80 countries. These treaties do not usually stop you becoming a Turkish tax resident, but they:
- decide which country has the primary right to tax a specific type of income (salary, pension, business profits, dividends, etc.),
- and allow foreign tax credits in Turkey for tax already paid abroad, so that the same income is not taxed twice in full.
Most treaties have “tie-breaker” rules: if both countries claim you as a resident, they look at your permanent home, centre of vital interests, habitual abode and sometimes nationality to decide a single treaty residence. That treaty residence can change the way your income is taxed, even if under domestic law you are still a Turkish resident.
3. Practical scenarios
a) UK company remote worker
You are a UK citizen, employed by a UK company, working remotely from Istanbul.
- If you spend less than 183 days in Turkey in a year and do not have a settled home here, Turkey will usually see you as non-resident. In practice, salary paid from the UK and taxed there may remain outside Turkish tax, unless the authorities argue that work is physically performed in Turkey and creates a Turkish source.
- If you spend more than 183 days or clearly move your life to Turkey, you become a Turkish tax resident. Your UK salary then becomes worldwide income taxable in Turkey, subject to relief under the UK–Turkey tax treaty. Under that treaty, employment income is typically taxed where the work is actually carried out – in this case, Turkey – with UK tax (if any) credited.
Your UK employer may also face payroll or even permanent-establishment questions; many companies in practice require contractors instead of employees once staff relocate full-time to Turkey.
b) Dubai-company trader / digital entrepreneur
You own or work for a Dubai company (with no personal income tax in the UAE) and trade crypto, FX or e-commerce worldwide, mostly from Antalya or Bodrum.
- If you are in Turkey over 183 days or clearly treat Turkey as home, the Turkish tax office can consider you a full taxpayer. Your salary, director’s fees or business profits – even if paid from Dubai – can be treated as taxable worldwide income in Turkey.
- In some cases, if the effective management of the company is found to be in Turkey (board decisions, key management, servers, staff), there is a risk that Turkey could argue the company itself is resident here, exposing it to Turkish corporate income tax as well.
There is currently no broad Turkey–UAE treaty covering all income types, so careful structuring and documentation are essential.
c) EU pensioner living in Turkey
You are an EU citizen who retires to the Aegean coast and receives a pension from your home state.
- If you live in Turkey long term, you will usually become a Turkish tax resident.
- How your pension is taxed then depends on the relevant tax treaty: some treaties tax private pensions only in the state of residence (Turkey), others allow the source state to tax and give a credit or exemption in Turkey; many treaties treat government pensions differently from private employer pensions.
Result: in some specific country pairings, foreign retirees may in practice pay little or no Turkish tax on their foreign pension; in others, Turkey expects a declaration and will credit foreign tax. You cannot assume exemption without checking the exact treaty.
4. Risks of not declaring worldwide income as a Turkish resident
Once you are a full taxpayer, failing to declare your worldwide income can trigger:
- Tax audits and investigations, increasingly supported by international automatic exchange of financial account information between tax authorities.
- Tax loss penalties – typically 50–100% of the unpaid tax – plus late-payment interest and fixed “special irregularity” fines for non-compliance with reporting obligations.
- In serious or deliberate cases, possible criminal charges for tax fraud under the Tax Procedure Law (e.g. using fake invoices or concealing records), punishable by imprisonment.
Turkish law does provide options such as “regret and correction” (Article 371 TPL) and restructuring programmes that allow voluntary disclosure of undeclared income with reduced penalties – but these are time-sensitive and should be used with professional advice.
5. Crypto and e-commerce income
Crypto assets
Turkey has introduced a regulatory framework for crypto asset service providers and is preparing detailed legislation on crypto. New rules define crypto assets and license exchanges and custody providers, and they make it clear that earnings from crypto assets will be subject to taxation, even though the exact method (capital gains vs. commercial income, rates, thresholds) is still being clarified.
The Revenue Administration has already stated that income derived from crypto assets is taxable under existing rules, whether as trading profits or other income. For a Turkish tax resident, this means crypto trading, DeFi yields or similar income should be analysed and, where taxable, declared, regardless of whether the exchange is based abroad.
E-commerce and online business
If you are resident in Turkey and run an online store, drop-shipping business, content-creator activity or other e-commerce operation, profit is usually treated as commercial income taxable in Turkey, even if your customers and platforms are abroad.
Payment processors, banks and marketplaces increasingly share data with the Turkish tax authority, and cross-border digital businesses are one of the focus areas in recent tax audits.
6. Practical tips for foreigners
- Track your days. Keep a clear log of your physical presence in Turkey and elsewhere.
- Confirm your status early. Before you cross 183 days or move family and home to Turkey, get a tax-residency analysis.
- Map your treaty position. Check the specific DTA for your passport country and any other country where you have income.
- Organise documentation. Bank statements, exchange reports, broker summaries, pension slips and platform dashboards are crucial if the tax office asks questions.
- Get professional advice. A Turkish tax adviser can help you file correct returns, claim treaty relief and, where necessary, use voluntary-disclosure tools to fix past years.
