We've gathered answers to the most common questions about the B2B calculator and taxes for sole traders in Poland. If you can't find your answer, feel free to reach out via the contact page.
The B2B calculator is a free online tool that helps entrepreneurs and freelancers estimate their net take-home pay when running a sole trader business (JDG) in Poland. Just enter your monthly revenue and select a tax form — in seconds you'll see how much you keep after paying taxes and ZUS contributions.
Results are approximate and for informational purposes only — they help estimate the tax burden but may differ from your actual tax liability. The real amount depends on your individual financial situation, available deductions and other factors. We recommend consulting a licensed tax advisor or accountant before making financial decisions.
B2B revenue is the net value of invoices issued (excluding VAT) in a given month. Enter that amount in the 'monthly net revenue' field — the calculator will automatically compute income tax, ZUS contributions and your final net take-home pay. Note that revenue is recognised when the service is performed, regardless of when payment is received.

You can choose from three ZUS variants: start-up relief (no social contributions for the first 6 months), preferential ZUS (reduced contributions for 24 months after the relief ends) and full ZUS (standard contributions).

Yes. The B2B calculator supports all three of Poland's most popular tax forms: flat-rate (ryczałt, rates 2%–17%), linear tax (19%) and progressive scale (12%/32%). Results for each form are computed automatically when you select an option.
The net amount depends on your revenue, tax form and ZUS type. With 10,000 PLN monthly revenue under linear tax and full ZUS, the approximate net take-home is around 7,000–7,800 PLN. Enter your own figures in the calculator to see the exact result instantly.
