ZUS Calculator — Mandate Contract (Umowa Zlecenie) 2026

This calculator computes the employee-side ZUS social security contributions payable on a Polish mandate contract (umowa zlecenie). It covers three scenarios: student under 26 (no ZUS), mandate as an additional income source (health contribution only, 9%), and mandate as the main income source (full contributions: pension 9.76%, disability 1.5%, sickness 2.45%, health 9%).

How we calculate ZUS on a mandate contract

Social contributions are calculated from gross pay: pension (9.76%), disability (1.5%), voluntary sickness (2.45%) — totalling 13.71%. Health contribution base = gross − social contributions; health = base × 9%. Students under 26: no ZUS or PIT. Additional mandate (not sole source): health contribution only.

Example: PLN 3000 gross, main income source

For a non-student contractor earning PLN 3000 gross (main income source): pension = PLN 292.80, disability = PLN 45.00, sickness = PLN 73.50, health base = PLN 2588.70, health contribution = PLN 232.98. Total employee ZUS: approx. PLN 644.28.

Frequently asked questions

What ZUS contributions are due on a Polish mandate contract (umowa zlecenie)?

When the mandate is the sole or main source of income, the employee pays: pension (9.76%), disability (1.5%), voluntary sickness (2.45%), and health (9% of the base after social deductions). If the mandate is an additional income source alongside a full-time employment contract, only the health contribution is compulsory.

Are students exempt from ZUS on a mandate contract?

Yes. Students and pupils up to the age of 26 are fully exempt from both ZUS social contributions and PIT income tax on mandate contract income. The employer also pays no social contributions for them.

Is sickness insurance (chorobowe) compulsory on a mandate contract?

No. Sickness insurance (2.45%) is voluntary for mandate contract workers. If you opt in, you are entitled to ZUS sickness benefit (zasiłek chorobowy) when you fall ill. If you do not opt in, you receive no sickness benefit from ZUS.

An employment contract (umowa o pracę) always carries full mandatory ZUS contributions. A mandate contract carries full ZUS only when it is the main income source. If a person also holds an employment contract with a salary at least equal to the minimum wage, only the health contribution is required on the mandate.

The employer pays pension (9.76%), disability (6.5%), accident insurance (variable, typically 1.67%), and Labour Fund (2.45%) on top of the employee's gross pay. This calculator shows only the employee-side contributions.

The health contribution base = gross remuneration minus social insurance contributions (pension + disability + sickness) paid by the employee. The health contribution is then 9% of this base.

Yes. From January 2026, the minimum hourly rate for mandate contracts is set by regulation. For 2026, the minimum hourly rate is PLN 30.50. This is separate from the monthly minimum wage (PLN 4,666) applicable to employment contracts.

If both contracts together generate a base at least equal to the minimum wage, one or both may be exempt from social contributions (only health required). If neither meets the threshold alone, both are subject to full social contributions until the combined base reaches the minimum wage level.

Only if you voluntarily opted into sickness insurance (chorobowe) and have been insured for at least 90 consecutive days. The benefit is paid by ZUS at 80% of the assessment base (or 100% during hospitalisation or after the 33rd day for workers over 50).

No. The tool is for informational purposes and uses 2026 contribution rates. It does not include PPK contributions, employer-side ZUS, or PIT withholding. For official confirmation, check with ZUS or a qualified payroll advisor.
