How are Turkish fund gains taxed if I don't live in Turkey?

Gains on Turkish investment funds are subject to withholding tax (stopaj) deducted at source. You do not receive a gross gain and settle up later; the intermediary withholds on redemption and what reaches your account is already net.

The rates, and why they move

The ordinary rate for most funds is a flat percentage of the gain, set by presidential decree — which means it changes, sometimes at short notice and sometimes retroactively in effect for funds bought before the change. Two structural exceptions matter:

• Equity-intensive funds (hisse senedi yoğun fon) have historically carried a 0% rate. That is a policy choice, not a law of nature, and it has been revisited before.
• Pension (BES/OKS) funds are taxed on a completely different, tenure-based schedule — lower the longer you stay in the system, lowest at retirement. That regime has nothing to do with the ordinary one.

This site shows the rate applicable to each fund as we understand it at the time of writing. Treat it as a starting point for a conversation, not as a filing position.

The part that is actually about you

Withholding at source answers Turkey's claim on the gain. It says nothing about your own country's.

If you are tax-resident somewhere else, your home jurisdiction may tax the same gain again, may credit the Turkish withholding against its own charge, or may exempt it — depending on whether a double-taxation treaty exists between your country and Turkey, and on how that treaty classifies fund income. Some treaties treat collective investment vehicles quite differently from direct securities holdings.

We cannot tell you which applies to you, and we are not going to guess. The combination of your residence, your nationality, the fund's legal type and the specific treaty text determines the answer, and getting it wrong is expensive in a way that reading a website is not. This is the point at which you talk to a tax adviser in the country where you file.

What you can do here

Look up any fund on this site and you will see the withholding treatment it carries, alongside the returns. What you should carry away from that figure is the shape of the outcome — that a headline return is not what lands in your account — rather than a number to put on a form.
