Do You Still File a Turkish Tax Return?

The short answer: it depends what else you earn

If your only income is exempt foreign-source income under the 20-year regime, there is nothing to declare from it — exempt foreign income is not declared and is not included in any Turkish return you file for other income. But "no declaration of the exempt income" is not the same as "no filing obligations at all". The moment you also have Turkish-source income, or you fall within other Turkish taxes, ordinary rules apply and a return may well be required.

Exempt foreign income stays off the return

This is the cleanest part of the regime. Foreign dividends, foreign interest, foreign rent, foreign capital gains, foreign employment or business profit and foreign pensions — where they qualify — are simply outside the Turkish income tax system for twenty years. You do not enter them on a Turkish return, and you do not add them to other income to push yourself into a higher band, because they are not part of the tax base at all. If you file a Turkish return for some other reason, the exempt foreign income does not go on it.

Turkish-source income still means filing

The exemption never touched Turkish-source income, and the filing rules for it are unchanged. If you earn a Turkish salary, run a business in Türkiye, or receive Turkish rent, those amounts are taxed under the normal rules and are declared in the ordinary way. Watch the remote-work grey area here: work performed while you are physically in Türkiye may be treated as Turkish-source even if the payer is abroad — see the Turkish-source income trap — which can turn income you assumed was exempt into income you must declare.

Other taxes still apply

Income tax is only one part of the system. Being within the exemption does not switch off the other Turkish taxes, each with its own obligations and payment mechanics:

So the practical filing question is not "do I benefit from the exemption?" but "do I have any Turkish-source income or other taxable dealings?" If yes, you are in the normal system for those; if your only income is qualifying foreign income, the exempt side generates no declaration.

Keep your records — the burden is on you

Because a wrongful exemption claim is treated as lost tax — tax evasion — attracting an assessment plus penalties and interest, the value of good record-keeping is hard to overstate. The exemption's implementing communiqué is reserved to the Ministry of Treasury and Finance and has not yet been fully issued, so keep documentation robust while the detail settles.
