Minimum income tax – check if it is your company’s concern

Dorota Białas

September, 24th 2025​​​​​​​


Minimum corporate income tax on companies showing losses or profitability below 2% has been in place since 2024. The profitability ratio is not evident directly from the CIT figures, and the calculation methodology may vary.

The tax rate is generally 10% but the lawmakers have exempted certain entities and transactions.
The tax due date for the current year is 31 March 2026. That is why we recommend starting now to:

check if your company is subject to minimum tax;
simulate the potential tax burden.

The minimum income tax is a new challenge for many businesses. If your company operates at a low rate of return or suffers a loss, check if it is subject to the new legislation. Early preparation brings greater ease and better readiness for payment.
