How This Calculator Works
Enter your investment gain or income and the rate (19%). The calculator shows the tax due; subtract it from the gain to see the net. The Belka tax applies to most capital income in Poland — bank-deposit interest, dividends, bond interest, and capital gains on shares and funds. For interest and dividends it's usually withheld at source by the bank or broker; for share gains you settle it via your annual return.

Worked Example
At 19% on a 10,000 zł investment gain, the Belka tax is 1,900 zł, leaving 8,100 zł net. The 'podatek Belki' — named after former finance minister Marek Belka, who introduced it — is Poland's flat 19% tax on capital income. It covers interest on bank deposits and bonds, dividends, and capital gains from selling shares, ETFs and fund units. For deposit interest and dividends the tax is typically deducted automatically; for gains on securities you report them on the annual PIT-38 form and pay the 19%.
Key Insight
The Belka tax is the standard charge on Polish savings and investing, and a few features shape how much you actually pay. It's a flat 19% on capital income, regardless of your income-tax bracket, covering bank-deposit and bond interest, dividends, and capital gains on shares, ETFs and investment-fund units. Collection differs by type: for deposit interest and dividends, the bank or paying agent withholds the 19% at source, so the income reaches you net and there's nothing to file; for capital gains on securities, the tax is not withheld — your broker issues a PIT-8C statement and you compute and pay the 19% via the annual PIT-38 return. A practical advantage on the gains side is loss offsetting: capital losses can be set against capital gains (and carried forward for several years), so only your net gain is taxed — this calculator taxes the amount you enter, so enter the net gain after losses. The most important way Poles legally avoid the Belka tax is through dedicated retirement accounts: an IKE (individual retirement account) lets gains and withdrawals be free of the Belka tax if conditions (age and holding period) are met, and an IKZE gives an income-tax deduction on contributions with a reduced flat tax at payout — so using IKE/IKZE shelters investments from the 19% entirely or partly. There has been recurring political discussion of introducing a tax-free allowance for savings interest to soften the Belka tax for small savers, but the flat 19% remains the rule. This calculator shows the 19% on the gain you enter and the net; for your real position, offset losses against gains first, and consider whether the investment sits in an IKE/IKZE that would exempt it.

Is the tax withheld automatically?
It depends on the income type. For deposit interest and dividends, the bank or paying agent withholds the 19% at source, so the income arrives net. For capital gains on securities it isn't withheld — your broker issues a PIT-8C and you calculate and pay the 19% through the annual PIT-38 return.
Can I offset losses?
Yes, on the capital-gains side — capital losses can be set against capital gains and carried forward for several years, so only your net gain is taxed. Enter the net gain after offsetting losses into this calculator. Note that deposit interest is taxed gross and can't be reduced by investment losses.
How can I avoid the Belka tax?

Methodology & Review
The tax is the rate applied to the investment gain or income; the total here is the gain plus the tax figure so the tax (chargeAmount) and net gain are easy to read off. It models the flat 19% rate and does not apply exemptions (e.g. IKE/IKZE retirement accounts), the offsetting of losses against gains, or any proposed savings-interest allowance.
