If you live in Poland, chances are you’re considered a Polish tax resident. That means you are required to declare all your capital gains—no matter where in the world they were generated. This obligation applies to profits earned from your investment accounts, including foreign brokerage accounts.

What You Need to Know

Many investors are unaware that the obligation to file a capital gains tax declaration applies even if their investment account shows a negative result for the year. Yes, even a loss must be reported.

If you lived in Poland in 2024—even temporarily—you are likely required to file a tax return by April 30, 2025, using the PIT-38 form.

This is especially important for those who use non-Polish online brokers, such as DEGIRO, eToro, or Interactive Brokers. These platforms do not submit tax forms on your behalf to the Polish tax office, which means the responsibility is entirely yours.

Foreign Accounts? Polish Authorities May Already Know

Don’t assume your foreign brokerage account is “invisible.” Due to international tax information exchange agreements, the Polish tax administration receives detailed information about accounts held by Polish residents with foreign institutions. In fact, recent audits have specifically focused on users of DEGIRO, eToro, and Interactive Brokers.

What Triggers the Obligation?

You must file a PIT-38 if any of the following occurred in 2024:

• You sold stocks, ETFs, crypto, or other financial instruments
• You received dividends
• You purchased crypto assets—even without selling them
• Your brokerage account shows a loss or zero gain

Even simply holding certain foreign financial instruments may create an obligation to declare.

Can You Deduct Previous Losses?

Yes. If you reported losses in previous tax years, you can offset them against future gains. But the key is to stay compliant and consistent in filing your annual declarations.

Don’t Wait Until the Last Minute

The deadline is April 30, and last-minute filing often leads to mistakes or missed opportunities to deduct past losses. Start early and take control of your tax situation.
