4+ Families relief (PIT-0)

Who is eligible?

  • Parents (including foster parents) raising at least 4 children
  • Legal guardians caring for ≥4 children
  • Applied independently to each parent (a married couple: 2 × PLN 85,528)
  • Qualifying children: minors, adult disabled children, adult full-time students (up to age 25) with own annual income below PLN 21,371.52

The relief must be confirmed each year — only if the parent actually exercised parental authority / served as guardian / foster parent during the tax year. Part of a year is enough (e.g. the 4th child born in November).

How the relief works and how to file

Exempt income

Up to PLN 85,528/year from employment contracts, civil-law contracts (including work-for-hire up to age 26), graduate internships, apprenticeships, and non-agricultural business activity taxed on the progressive scale, flat tax, or lump-sum tax.

Combining with the tax-free allowance

The PLN 30,000 tax-free allowance applies independently — it is not included in the PLN 85,528 limit. Effective PIT-free range: ~PLN 115,528 per year.

How to file

In the PIT-37 or PIT-36 return in the appropriate box (income exempt under Art. 21(1)(153)). Add the PIT/O attachment with information on the number of children.

First-bracket savings

Max ~PLN 10,263/year (85,528 × 12%). At income > PLN 120,000 further 32%-bracket savings apply, but the rules are more complex — consider a tax adviser.

Frequently asked questions

Does the 4+ relief combine with the pro-family (child) tax credit?
Yes, these are two separate reliefs. The 4+ relief exempts income up to PLN 85,528; the pro-family credit (Art. 27f) is a deduction from tax (PLN 1,112 × 2 + 2,000 + 2,700 × each further child). With 4 children, the combined annual benefit can reach ~PLN 7,900 credit + up to ~PLN 10,263 of PIT-0.
Which children count toward the 4+ requirement?
Minors (under 18), adult children receiving a nursing allowance or social pension, and adult full-time students (up to age 25) whose own income in the year did not exceed PLN 21,371.52 (12× the social pension 2026).
Do I need to have 4 children the whole year?
No — the condition is met even if the 4th child appeared only, say, in November. The relief then covers the whole tax year.
Can divorced parents each claim independently?
Each parent applies the relief independently if they actually raise ≥4 children — in practice both typically qualify, provided the statutory conditions are met for all children.
Does the relief cover civil-law contracts?
Yes — the act explicitly lists: employment, civil-law contracts, work-for-hire (for people under 26), graduate internships, apprenticeships, and business activity (scale / flat / lump sum). Excluded: capital gains and private rental income.
