How ryczałt it in Poland is calculated

Poland's ryczałt (lump-sum tax) regime is a genuinely different shape from most income tax: it is charged on gross revenue, not profit, at a rate set by the specific activity rather than a universal scale — anywhere from 2% to 17% depending on classification.

Programming and IT services get one of the most favourable rates in the whole table: 12%, flat, on every złoty of revenue, with no expense deduction at all — which is exactly why it needs none: the low rate already assumes costs are modest relative to a service business's revenue.

It is available to anyone below 2,000,000 EUR of prior-year revenue, which covers essentially every individual IT contractor. The trade-off is that ryczałt cannot deduct real costs — a contractor with unusually high documented business expenses (hardware, subcontractors) might do better under the standard scale or flat 19% regimes instead, which this page does not model.

Worked example

200,000 PLN revenue, a typical IT contractor
Annual revenue (PLN)200000
Ryczałt tax (12%) 24000
Net income / year (before ZUS) 176000

Every row is computed by the engine from the inputs above. Rows marked ✓ are additionally pinned by a published self-test vector.

Frequently asked questions

How much net income from 200,000 PLN revenue in Poland?

At the 12% IT rate, tax is 24,000 PLN, leaving 176,000 PLN net income tax — before ZUS social and health contributions, which are a separate, largely flat monthly cost this page does not include.

Why 12% specifically for IT?

Ryczałt sets rates by activity, from 2% to 17%; the government set 12% for computer-programming-related services specifically to keep the regime competitive for the IT contracting sector.

Can I deduct expenses under ryczałt?

No — the whole point of the flat rate is that it replaces expense deduction. A contractor with high real costs relative to revenue may do better on a different regime (the standard scale or flat 19%), which this page does not model.
