FAQ

When do I pay 4.9% and when 9%?: 4.9% — when you are on the general rules (scale), linear (19%) or with books; you deduct this contribution from the PIT advance. 9% — when you are on ryczałt; you do not deduct this from the advance.
What is the health contribution base?: Under ryczałt — on revenue. Under scale/books/linear — on income or on a statutory amount (e.g. minimum base), depending on the regulations. The calculator uses the amount you enter as the monthly base.
Do I pay the health contribution every month?: Yes. The self-employed pay the health contribution monthly (with ZUS or in the tax settlement, depending on the form).
Does the calculator include the minimum base?: No. The calculator multiplies the given base by the rate. In practice a minimum base may apply — check current regulations (ZUS, MF).
Where to check current rates and rules?: Act on healthcare benefits financed from public funds and PIT regulations (MF, gov.pl). Rates may change.
