Maternity benefit (in Polish, zasilek macierzynski) in Poland is not limited to employees. Self-employed people and those running a sole proprietorship or B2B activity can also receive it, provided they pay voluntary sickness insurance to ZUS. This guide explains who qualifies, how the benefit is calculated and how much you can realistically expect.
Who is eligible?
A self-employed person qualifies for maternity benefit if they are covered by voluntary sickness insurance (ubezpieczenie chorobowe) at ZUS at the moment of childbirth. Unlike sick pay, there is no minimum waiting period for maternity benefit — even one day of voluntary sickness insurance before the birth can entitle you to it. This is a key difference that many self-employed parents overlook.
How is the benefit calculated?
The benefit is based on the average declared contribution base over the 12 months preceding the month of childbirth, minus a 13.71% deduction representing social contributions. The benefit rate depends on the chosen leave structure:
- 100% of the base for the basic maternity-leave period.
- 70% for the parental-leave portion if taken separately.
- 81.5% as a flat rate if you apply for the full combined leave upfront.
Why the declared base matters
Self-employed people choose their own contribution base within legal limits. Because maternity benefit is calculated from the average base of the previous 12 months, declaring a higher base before the birth increases the benefit — but only if done consistently and well in advance, since a single high month is averaged out. Planning the contribution base ahead of pregnancy is therefore a legitimate and important strategy.
Worked example
Suppose a self-employed mother declared an average monthly base of 7,000 PLN over the previous 12 months and chooses the flat 81.5% option.
- Base after 13.71% deduction: 7,000 - 959.70 = 6,040.30 PLN
- Monthly benefit at 81.5%: 6,040.30 x 0.815 = about 4,922 PLN
If instead she declared only the minimum base, the benefit would be a few hundred zloty per month — illustrating why the declared base is so important.
How long is the benefit paid?
The total entitlement combines maternity leave and parental leave, generally amounting to 52 weeks for a single child, with more for multiple births. The benefit is paid monthly by ZUS for the entire period, as long as the self-employed activity does not generate income during that time in a way that conflicts with the rules.
