How this is calculated

Compute the standard "duży ZUS" social contributions on the fixed statutory monthly base (5,652 PLN for 2026) — these are the same each month regardless of your actual profit, and they are deductible from the PIT base.
Compute the health contribution at 9% of your income, subject to a monthly minimum (9% of the minimum wage, 4,806 PLN, from 2026). It is not deductible from tax.
Work out the PIT base: your net income minus the deductible social ZUS.
Apply PIT on the scale (12% up to 120,000 PLN, 32% above, less the 3,600 PLN reducing amount). Net income = income − social ZUS − health − PIT.

FAQ

What is 'duży ZUS'?

It is the standard social-insurance regime for established sole traders, charged on a fixed statutory base (about 60% of the forecast average wage — 5,652 PLN in 2026) rather than on your actual profit. New businesses can use reduced starter regimes for the first months and years.

How is the self-employed health contribution calculated on the scale?

On the progressive scale it is 9% of your income, with a monthly minimum equal to 9% of the minimum wage. From 2026 the minimum base rose to 100% of the minimum wage (4,806 PLN), raising the minimum monthly health contribution to about 432.54 PLN. It is not deductible from PIT.

What about the linear (19%) and lump-sum (ryczałt) regimes?

Polish sole traders can also choose a flat 19% tax (podatek liniowy) or a turnover-based lump sum (ryczałt), each with its own health-contribution rules. This calculator covers only the progressive scale (skala); the other regimes can be more favourable depending on income and costs.
