Q1.I have a double taxation agreement with the country that pays me. Does that mean I don't pay tax in Türkiye?
No, and this is the single most common misunderstanding about tax here. A treaty stops the same income being taxed twice; it does not remove Türkiye from the picture and it does not remove the filing. If you are a Turkish tax resident you declare the income on a beyanname and then claim the treaty relief — the relief is something you claim, not something that happens automatically because tax was already withheld abroad. In many cases the outcome is that you owe nothing extra here, and that is why the misunderstanding survives: people see the outcome and assume it is the rule. The two are different, and the difference is a filing obligation.
Q2.My employer already withholds tax in their country. Do I still have to declare it here?
Yes, if you are a Turkish tax resident. Withholding abroad is tax paid abroad — it is the input to your relief calculation, not a substitute for declaring. There is also a case worth knowing: most treaties give the taxing right on employment and professional income to the country where the work is physically performed. If you sit in Türkiye and do the work, that is here, whoever employs you and wherever they pay. In that situation your employer may be withholding in a country that does not hold the primary claim, which means you are not exempt in Türkiye — you may be owed a refund there instead. Getting this the wrong way round is expensive in both directions, so it is worth an hour with a mali müşavir.
Q3.What if the Turkish tax rate is higher than what I already paid abroad?
Then the difference can be collected here. Relief under a treaty is not a discharge — the usual mechanism is a credit for foreign tax paid against the Turkish liability on the same income, so if the Turkish figure is larger, the gap remains payable. Turkish income tax runs 15-40% depending on the band, so whether a gap exists depends entirely on your income level and the other country's rates.
Q4.Does my residence permit make me a Turkish tax resident?
No. These are two different offices making two different decisions, and confusing them is the most expensive mistake foreigners make here. A residence permit is immigration status. Tax residency is decided separately — principally by spending more than 183 days in Türkiye in a calendar year, and also by the 'centre of vital interests' test, which can treat you as resident on fewer than 183 days if your home, family and daily life are obviously here. You can hold a permit and not be tax-resident, and you can be tax-resident without one.
Q5.I work remotely for a foreign company and get paid into a foreign account. Is that taxable in Türkiye?
If you are a Turkish tax resident, yes — your worldwide income is in scope, and the money never touching a Turkish bank changes nothing about that. This is the assumption that causes the most trouble: 'my client is abroad and my bank is abroad, so this is not Turkish income.' The tax authority does not read it that way, and it increasingly has access to foreign bank and brokerage data through international agreements. Treaty relief may reduce what you actually pay; it does not remove the obligation to declare.
Q6.Does the new Law 7582 exemption mean my foreign income is tax-free?
Only in narrow circumstances, and one condition disqualifies most people who get excited about it. Law No. 7582, in force since 4 June 2026, added Article mükerrer 20/D to the Income Tax Law: qualifying NEW tax residents can receive foreign-source income at 0% Turkish income tax for 20 years, backed by an exemption certificate from the GİB. The condition that decides most cases is what counts as 'foreign-source' — it turns on where the economic activity physically takes place, not where your client sits or what currency pays you. The communiqué's own worked example holds that an engineer working in Türkiye for foreign clients earns Turkish-source income and is not exempt. A business genuinely operated abroad can qualify; the same business run from a desk in İstanbul cannot.
Q7.What are the conditions and deadlines for the Law 7582 exemption certificate?
You must arrive as a genuinely new tax resident, with no Turkish domicile or tax liability during the previous three calendar years — so filing once before you check can close the door. The certificate has a hard deadline, and arriving in November or December pushes it to the end of February of the following year; the communiqué's own worked example shows a missed deadline simply results in refusal, with no published cure. Three further published details matter for planning: exempt income stays off the annual return entirely, foreign taxes paid on that income cannot be credited in Türkiye, and related expenses are not deductible. Speak to a mali müşavir before you file anything, not after.
Q8.I spent fewer than 183 days in Türkiye. Am I safe?
Not automatically. The 183-day count is the main test but not the only one: under the 'centre of vital interests' rule, if the tax authority examines your file and concludes you clearly live your life in Türkiye — a home here, your family here, your affairs run from here — you can be treated as resident with fewer than 183 days in the country that year. There is no day counter that protects you from that assessment, which is why anyone close to the line should have it looked at rather than assume.
