Bonus after tax in Poland 2026: what is left after tax and ZUS

Three bonuses on three salaries

Net figures are for a bonus paid in January together with salary, with PIT-2 filed and work costs of PLN 250.

The rows are practically identical. The fixed allowances (work costs of PLN 250 and the PLN 300 tax-reducing amount) are already used up by the salary itself, so every złoty of bonus passes through the same percentage deductions. Early in the year a bonus is worth exactly as much to someone on PLN 6,000 as to someone on PLN 15,000.

A December bonus: when the second bracket takes more

The second table compares a PLN 10,000 gross bonus paid in January with the same bonus paid in December, after eleven months of steady salary.

At PLN 8,000 gross the payment month makes no difference, because the taxable base never gets near PLN 120,000 by year end. At PLN 12,000 the December salary alone fills what is left of the first bracket, so the whole bonus lands in the second, just as it does at PLN 15,000: both lose the same amount in December, because the entire bonus is taxed at 32 %. At PLN 25,000 the PLN 282,600 cap also comes into play: cumulative gross passes it in December, so part of the bonus no longer carries pension and disability contributions, which partly offsets the higher tax; PLN 5,755 remains.

Where the deductions from a bonus come from

On a Polish payslip (pasek wypłaty) the bonus appears as a separate income line, but deductions are worked out on the total. Social contributions of 13.71 % and the 9 % health contribution are proportional to the amount. The tax advance depends on which bracket your cumulative taxable base is in. The label does not matter: a discretionary bonus, a contractual one, a quarterly bonus or an annual award are all settled the same way, provided the employer pays them under an employment contract.

A bonus also raises your cumulative base for the rest of the year. A large payment in spring can therefore bring forward the month you enter the second bracket and lower the net on your salary in the final months, even if the bonus itself was taxed at 12 %. The annual salary calculator shows this effect.

What the bonus calculator leaves out

The tool assumes a bonus paid in January, before the second bracket and before the contribution cap. It does not handle bonuses on mandate or B2B contracts, where extra money is simply a higher contract fee or a larger invoice. It ignores PPK: if you are a member, your 2 % contribution is also taken from the bonus and the employer's payment raises your tax. It also leaves out the under-26 youth relief, under which a young employee's bonus is exempt from income tax up to PLN 85,528 a year. For net pay on your salary with those options, use the salary calculator.

If your bonus falls late in the year, check from when your salary is taxed at 32 %.
