Capital Gains Tax in Poland - the Belka Tax Explained (2026)

Poland charges a flat 19% Belka tax on capital gains and investment income. Learn what it covers, how to report it on the PIT-38 form and how to calculate it.

If you invest in Poland - whether in shares, ETFs, bonds or cryptocurrency - you will sooner or later meet the so-called Belka tax. Named after former finance minister Marek Belka, it is a flat 19% levy on most forms of capital and investment income. This guide explains what the tax covers, how it is reported and how to estimate what you owe, so there are no surprises when tax season arrives.

What is the Belka tax?

The Belka tax (podatek od zyskow kapitalowych) is Poland's flat-rate tax on income from capital. Introduced in 2002, it applies a single rate of 19% regardless of how much you earn. Unlike the progressive personal income tax scale, there are no thresholds or tax-free allowances for most capital gains - the first zloty of profit is taxed at the same rate as the last.

What income does it cover?

The 19% rate applies to a broad range of capital income, including:

  • Interest on bank deposits and savings accounts
  • Dividends from shares
  • Profits from selling shares, ETFs and other securities
  • Gains on bonds and investment funds
  • Profits from cryptocurrency disposals
  • Income from certain derivative instruments

For interest and dividends, the tax is usually withheld automatically by the bank or broker, so you receive the net amount. For gains on selling securities and crypto, however, you generally have to declare them yourself.

The PIT-38 form

Gains from disposing of shares, ETFs, derivatives and similar instruments are reported on the annual PIT-38 form. Your brokerage issues a PIT-8C statement summarising your transactions, which you use to complete the return. The deadline for filing PIT-38 and paying any tax due is 30 April of the year following the tax year. Importantly, you can offset losses against gains, and unused losses can be carried forward for up to five years, reducing future tax bills.

Worked example

Suppose during the year you sold shares for 50,000 zloty that you had bought for 38,000 zloty, and you also paid 400 zloty in brokerage commissions. Your taxable gain is 50,000 - 38,000 - 400 = 11,600 zloty. The Belka tax is 19% of 11,600 = 2,204 zloty.

Now suppose you also closed another position at a 3,000 zloty loss. You can offset it: 11,600 - 3,000 = 8,600 zloty of net gain, giving tax of 19% x 8,600 = 1,634 zloty. The ability to net losses against gains is one of the most valuable features of the system.
