The minimum social insurance contributions for sole proprietors in Poland increased by 8.6% in 2026, reaching 1926.76 PLN monthly, including the Fundusz Pracy and Fundusz Solidarnościowy.
In 2026, the base for calculating social insurance contributions rose due to the projected average national wage increase. This adjustment resulted in a fixed monthly social insurance cost of 1926.76 PLN for sole proprietors on general tax rules, covering pension, disability, accident insurance, and contributions to labor and solidarity funds.
From February 2026, the minimum health insurance contribution base for sole proprietors taxed by scale or linear tax is set at 4806 PLN, corresponding to the minimum wage.
The minimal health insurance base returned to 100% of the statutory minimum wage in 2026 after a temporary reduction in 2025. This change increased the minimum monthly health insurance premium to 432.54 PLN, applying to entrepreneurs taxed under general tax rules or linear tax, regardless of their actual income.
The total minimum monthly obligatory contribution for a sole proprietor under general tax rules including social and health insurance in 2026 is approximately 2359.30 PLN.
Combining the fixed social insurance contribution of 1926.76 PLN with the minimum health insurance premium of 432.54 PLN (from February 2026), the average monthly obligatory cost for health and social coverage reaches about 2359 PLN. This amount does not vary with income below the minimum base, imposing a substantial fixed cost for small-scale entrepreneurs.

Scientific View
From an economic perspective, fixed social insurance contributions create a threshold effect that can discourage formal entrepreneurship among low-income operators. Empirical models suggest that such fixed costs reduce labor market flexibility and can push marginal businesses into informality or closure, especially under economic uncertainty and competitive pressures.
Key Arguments
- Fixed contributions raise entry and exit costs for small firms.
- They reduce incentives to declare full income, affecting tax compliance.
- They disproportionately burden low-revenue entrepreneurs.
