Maternity benefit calculator — ZUS Poland

Maternity benefit is available to insured persons covered by the sickness insurance scheme: employees on employment contracts, contractors who have voluntarily joined sickness insurance, and self-employed individuals paying the sickness contribution. There is no waiting period — entitlement arises from the first day of insurance cover.

The assessment base is the average gross monthly salary earned over the 12 calendar months preceding the month of childbirth (or the shorter period of employment), reduced by the employee's ZUS contributions of 13.71% (pension 9.76% + disability 1.5% + sickness 2.45%). Bonuses, overtime and other salary components are included if they are normally paid during sick leave.

Maternity leave lasts 20 weeks (for one child born in a single birth). After it ends, both parents together are entitled to 32 weeks of parental leave, of which 9 weeks are reserved exclusively for the father or the other parent and cannot be transferred. In total, parents can take up to 52 weeks of paid leave funded by ZUS.

Variant A: 81.5% of the assessment base for all 32 weeks of parental leave — a fixed, steady payment. Variant B: 100% for the first 6 weeks, then 70% for the remaining 26 weeks — the total payout is lower. Variant A is generally more financially advantageous for the full duration. The choice is made before or at the start of the maternity leave by submitting the appropriate application to the employer or ZUS.

Yes. Maternity benefit is subject to personal income tax (PIT) at the standard rate (12% up to the threshold of PLN 120,000 per year, 32% above). ZUS acts as the tax withholder and deducts the monthly tax advance. The benefit is declared in the annual tax return (PIT-37). It is not subject to social security contributions (pension, disability, sickness).

Yes. The father (or other parent) can claim maternity benefit during paternity leave (2 weeks, 100% of the base) and during their share of parental leave. Both parents may take parental leave simultaneously, but the combined duration cannot exceed 32 weeks, with each parent's 9-week non-transferable portion counted separately.

Employees may end parental leave early and return to work full-time or part-time. If parental leave is combined with part-time work (up to half the working time), the benefit is reduced proportionally. The full 20-week maternity leave is mandatory and cannot be shortened below 14 weeks after childbirth — the mother must use at least that much.

Yes, provided they have been paying the voluntary sickness insurance contribution. Contributions must have been paid continuously for at least the required period. The assessment base for the self-employed is the declared contribution base (between PLN 3,499.50 and PLN 17,658.50 in 2026), not actual income, which is an important planning consideration.

The maximum is limited by the assessment base ceiling, which is 250% of the average monthly salary projected in the budget for the given year. In practice, employees with high salaries may find their benefit capped. The calculator uses the declared assessment base without applying any ceiling — for exact figures with the cap, consult ZUS directly.

No. The calculator is for informational and planning purposes only. The actual benefit amount is determined exclusively by ZUS based on individual employment records, pay slips and insurance history. Results may differ due to gaps in insurance, variable pay components and annual regulatory changes. Always verify with ZUS or an employment law specialist.
