Example 1
- Gain: 1,000
- Rate: 19%
Tax 190
Net 810
Typical flat withholding on one thousand of gain.
19% capital gains / investment withholding tax (Poland) calculator
The Belka tax calculator, Poland’s flat tax on investment gains, multiplies the gain you type by the rate. From 1000 of gain at 19% you lose 190 and keep 810. You type the gain, not the whole stake.
Tax = gain × rate/100. 1000 and 19% yield 190. Compute deposit interest first on term deposit.
Result
Gain (interest / capital gain) and Tax rate (%). The result shows up here.
How results are calculated
Belka tax on this page is capital-gains withholding: one rate times the gain you type. The default is 19%, a typical Polish withholding on interest or investment gain. Net = gain minus tax. There are no loss carryforwards, exemptions, or a return. You do not type principal, only the gain.
The first card uses 1000 and 19% and yields 190 tax and 810 net. 5000 is five times that: 950 and 4050. From 250 of deposit or account interest, 47.50 comes off and 202.50 remains. Same 19-to-81 split.
Type Gain (interest / capital gain) and Tax rate (%). The 1000 and 19 placeholders are the first example. Click Calculate and read tax and net. If you only know a deposit amount and a rate, compute interest on the term-deposit page first: 10000 at 5% for 12 months is 500 gross and then 95 of Belka tax.
Term deposit next door pairs simple interest with the same 19%. Savings interest does not take tax off. The two-bracket income-tax sketch, 12% and 32%, lives on the income tax page and does not replace Belka.
This is a withholding sketch from one number. Another rate, a pension wrapper exemption, or a loss to offset will change a real filing. 190 from a thousand is not an official confirmation.
Type 1000 and 19. Check 190 and 810. Then try 250 to see 47.50.
How to use the calculator
- In Gain (interest / capital gain), type the gain alone, for example 1000. Do not paste the whole principal.
- In Tax rate (%), leave 19 or type another scenario rate.
- Click Calculate. At 1000 and 19 you should see 190 tax and 810 net.
- Check the straight line: 5000 yields 950 tax, five times the first example.
- If you only know a deposit amount and rate, open term deposit first, then bring the interest here.
19% on 1000 of gain
Belka tax: 1000 × 0.19 = 190, net 810. From 250 of interest you lose 47.50. You type the gain, not principal.

FAQ
How much Belka tax is due on 1000 of gain at 19%?
190 tax and 810 net. 1000 × 0.19 = 190. A withholding sketch, not a tax filing.
What comes off 5000 of gain?
950 tax, 4050 net. Five times the thousand example, the same 19% rate.
What about 250 of interest?
47.50 tax and 202.50 net. 250 × 0.19 = 47.50. The field is still gain, not principal.
Do I type the whole 10000 principal?
No. The field is gain. From 10000 the calculator would take 1900, as if the whole stake were profit.
Is this a full investment tax filing?
No. One rate times one number. Losses, exemptions, and a return are not here.
How do I get 500 of deposit gain?
On the term-deposit page, 10000, 5%, and 12 months yield 500 gross. That is 95 of Belka tax and 405 net.
How is Belka different from income tax?
Here a flat rate on a gain. There two rates, a 120000 threshold, and an optional tax-free amount. Different tax, different fields.
Can I type 0%?
Yes, then net = gain. That is a scenario, not an exemption ruling.
Is 19% the only legal rate?
On the page 19 is the default number. Statute and exceptions live outside this page.
Does 810 depend on currency?
810 stays 810. The symbol only labels net, it does not multiply the tax.
