Jak obliczyć ratę kredytu?

Rata miesięczna zależy od kwoty kredytu, oprocentowania i okresu spłaty. Użyj kalkulatora kredytu, by obliczyć ratę, odsetki i całkowity koszt.

Czy na ryczałcie mogę odliczać koszty uzyskania przychodu?

Co do zasady nie — podatek liczysz od przychodu, nie od dochodu.

Jak dobrać poprawną stawkę ryczałtu?

Na podstawie rodzaju działalności i klasyfikacji PKWiU; przy wątpliwościach warto uzyskać interpretację lub opinię księgową.

Czy składka zdrowotna przy ryczałcie zależy od progu przychodów?

Tak. Składka zdrowotna jest ustalana progowo wg rocznych przychodów i podlega rozliczeniu rocznemu.

Lump‑sum tax calculator — rates & advances

How does the calculator work?

The calculator estimates the tax advance under ryczałt (lump-sum tax on recorded revenue) and the health contribution (4.9% deductible from the advance or 9% non-deductible for ryczałt payers). Enter monthly revenue and the ryczałt rate for your activity. The result is indicative; in practice advances are paid quarterly.

FAQ

Who can use ryczałt (lump-sum)?: Lump-sum tax on recorded revenue is a form of taxation for the self-employed whose revenue in the previous year did not exceed a set amount (currently 250,000 euro converted to PLN). Not all activities qualify — exclusions are in the PIT Act.
What ryczałt rates apply?: Rates are 2%, 3%, 5.5%, 8.5%, 14.5% and 17% — depending on the type of activity (annex to the PIT Act). E.g. 2% for certain trade and catering, 8.5% for some services, 17% for liberal professions. Check which rate applies to your activity before filing.
What is the difference between 4.9% and 9% health contribution?: 4.9% — contribution deductible from the tax advance (for those on general or linear tax). 9% — for ryczałt payers; not deductible from the advance, so you pay the PIT advance plus 9% health on the base.
What is the health contribution base under ryczałt?: Under ryczałt the health base is revenue (not income). The 9% rate applies to that base — not deductible from the advance. The calculator simplifies: it uses monthly revenue as the base; in practice other rules may apply (e.g. minimum base).
Does the calculator include quarterly advances?: No. The calculator shows a monthly estimate: ryczałt tax advance and health contribution. In practice PIT advances under ryczałt are paid quarterly; health — monthly. Full records are needed for the annual return.
Where to check current ryczałt rates?: Current rates and exclusions are in the PIT Act (Ch. 5a, annex) and on the Ministry of Finance and podatki.gov.pl websites. Rates may be updated by MF announcement.
