The full skill

General reference only. This skill is general tax reference material for AI-assisted work. It has not been reviewed for any specific employer's or employee's facts. Do not rely on it to run a payroll, file or pay without review by a qualified professional in Poland.

Which text of the law. PIT Act (ustawa z dnia 26 lipca 1991 r. o podatku dochodowym od osób fizycznych), consolidated text Dz.U. 2026 poz. 592; the later amendments (poz. 779, 846, 1079) do not touch the payroll articles used here. Social Insurance System Act (ustawa z dnia 13 października 1998 r. o systemie ubezpieczeń społecznych, "ZUS Act"), consolidated text Dz.U. 2026 poz. 199. Health Care Benefits Act (ustawa o świadczeniach opieki zdrowotnej finansowanych ze środków publicznych), consolidated text Dz.U. 2025 poz. 1461. Fund rates for 2026 come from the 2026 Budget Act, Dz.U. 2026 poz. 62.

Sibling skills. Residence, the annual PIT return, joint filing and business income: pl-income-tax. ZUS for the self-employed (including Mały ZUS Plus): pl-zus-contributions. Deductibility of salary costs for a company and withholding tax on payments abroad: pl-cit-corporate-tax. Pricing of staff recharges between related companies: pl-transfer-pricing. This skill does not repeat them.

Who this applies to

The employer as payer (PIT Act art. 32(1)). Every employer (individual, company or other unit) that pays salary under an employment relationship (stosunek pracy), a service relationship, outwork or a cooperative employment relationship must compute, withhold and pay monthly PIT advances (zaliczki).

The employer as ZUS payer (ZUS Act art. 16-17). The same employer computes the social contributions, deducts the employee's share from pay, adds its own share and pays the total to ZUS. It also deducts and pays the employee's health contribution (Health Act art. 85(1)).

Covered here: employees on an employment contract, resident or not, paid by a Polish employer.

Not covered here: civil-law contracts (umowa zlecenie, umowa o dzieło), which use art. 41 of the PIT Act and 20% costs (art. 22(9)(4)); board members' fees; the self-employed (see pl-zus-contributions); directors' fees paid to non-residents (see pl-cit-corporate-tax).

The taxable base

Social contributions. The base for pension, disability, sickness and accident insurance is the employee's gross pay (ZUS Act art. 18(1)). Pension and disability stop once the year's base passes PLN 282,600; the employer stops computing them from that point (art. 19(1), (3) and (5)). Sickness and accident have no cap. FP, FS and FGŚP use the pension base without the cap (Labour Market Act art. 259(1); Employee Claims Act art. 29(1)). FS follows the FP rules (Solidarity Fund Act art. 4(1)). FP and FS are due only where the monthly base is at least the minimum wage, and not for women aged 55 or more or men aged 60 or more (Labour Market Act art. 259(1), 261). No FP and FS for 12 months for a hire aged 50 or more who was registered unemployed in the 30 days before, or a referred unemployed hire under 30 (art. 262), and for 36 months after a return from maternity, parental or childcare leave (art. 263). FGŚP has no minimum-wage condition, but the same age, 50-plus, under-30 and return-from-leave exemptions apply (Employee Claims Act art. 9a-9c). Employer PPK payments are not part of the pension and disability base (PPK Act art. 26(5)).

Health contribution. 9% of the same base as pension, less the employee's own pension, disability and sickness contributions (Health Act art. 81(1) and (6)). There is no annual cap. Since 2022 it is not deducted from tax (the old art. 27b of the PIT Act is repealed).

PIT advance, month by month (PIT Act art. 32(4)).

  1. Start with the month's revenue from the employment: cash pay plus benefits in kind and other free benefits (art. 12(1)). Whether and when the employer's PPK payment counts here is on the "Not yet confirmed" line below.
  2. Deduct the standard costs (PLN 250, or 300 for a commuter who files the statement in art. 32(7)), or author's costs where the contract says so.
  3. Deduct the employee's social contributions withheld that month (9.76% + 1.5% + 2.45% = 13.71% while under the cap).
  4. Round the result to whole złoty (Tax Ordinance art. 63 § 1). This is the month's income.
  5. Apply 12%, or 32% once cumulative income from this payer is above PLN 120,000 (art. 32(2)). In the crossing month, split the income at the threshold. If the employee filed a statement that they will file jointly with a spouse or as a single parent (art. 6(2) or 6(4d)), all months stay at 12% where the expected incomes meet the conditions in art. 32(3).
  6. Subtract PLN 300 if the employee filed a PIT-2 statement with this payer (art. 31b(1)). Round the advance to whole złoty.

Reliefs. Revenue exempt under the under-26, relocation, parents of 4+ and working seniors reliefs is left out of steps 1 to 5 up to PLN 85,528 a year in total (art. 21(44)). Social and health contributions are still due on that pay. The payer applies the under-26 relief automatically unless the employee asks it not to (art. 32(6)); the other three need a statement from the employee (art. 31a(8)).

No advance. An employee who expects income under PLN 30,000 for the year can ask the payer not to withhold advances at all (art. 31c).

Penalties and interest

  • Payer liability. A payer who did not withhold, or withheld but did not pay, is liable for the tax with all its assets (Tax Ordinance art. 30 § 1 and § 3). Late payment interest runs at the art. 56 § 1 rate: 10.50% a year from 5 March 2026 (M.P. 2026 poz. 269).
  • Fiscal penal code. Not paying withheld tax on time: fine up to 720 daily rates or up to 3 years' imprisonment, or both (KKS art. 77 § 1). Not withholding or withholding too little: fine up to 720 daily rates or up to 2 years, or both (KKS art. 78 § 1). Amounts under the statutory threshold drop to a fiscal misdemeanour (art. 77 § 3, 78 § 3). Late PIT-11 information: fine up to 120 daily rates (art. 80 § 1). KKS consolidated text Dz.U. 2025 poz. 633.
  • ZUS. Late contributions carry late payment interest under the Tax Ordinance rules (ZUS Act art. 23(1)); none is charged if it would be under 1% of the minimum wage (art. 23(1a)). ZUS may also impose an additional charge up to 100% of unpaid contributions (art. 24(1a)). Failing to pay, report or file DRA on time is an offence with a fine up to PLN 46,000 (art. 98(1)).

Cross-border points

  • Work done abroad. The payer does not withhold advances on pay for work done outside Poland where that pay is or will be taxed abroad, unless the employee asks (PIT Act art. 32(9)). On the annual return, treaty-exempt foreign income uses exemption with progression (art. 27(8)) and other foreign income uses the credit method (art. 27(9)). Residence tests and the return: pl-income-tax.
  • Non-resident employees working in Poland. Advances are computed the same way. The payer sends the PIT-11 to the tax office for foreign persons (art. 39(1), referring to art. 3(2a)).
  • Social security. Within the EU, EEA and Switzerland, one country's social security applies at a time under Regulation (EC) No 883/2004 (art. 11-13). A posted worker or a person working in two or more states can stay in one system with an A1 certificate. Without an A1, Polish ZUS applies to work done in Poland.
  • Relocation relief. A person who moves residence to Poland can claim the art. 21(1)(152) relief for four consecutive years, within the PLN 85,528 shared cap.
  • Recharges. Salaries recharged between related companies are controlled transactions; see pl-transfer-pricing.

Worked examples

Example 1: PLN 10,000 gross a month, small company employer

An employee of a Polish sp. z o.o. with 9 or fewer insured earns PLN 10,000 gross a month in 2026. One job, lives in the same town, filed PIT-2, aged 35, not in PPK, no benefits in kind. Annual pay is PLN 120,000, so the pension cap (PLN 282,600) is never reached.

Employee social contributions. Pension 9.76% = PLN 976.00. Disability 1.5% = PLN 150.00. Sickness 2.45% = PLN 245.00. Total PLN 1,371.00.

Health. Base PLN 10,000 − 1,371 = PLN 8,629. At 9%: PLN 776.61.

PIT advance. Income = 10,000 − 250 − 1,371 = PLN 8,379. 12% is PLN 1,005.48; less the PIT-2 reduction of PLN 300 gives PLN 705.48, rounded to PLN 705. Cumulative income for the year is 12 x 8,379 = PLN 100,548, under PLN 120,000, so all twelve months stay at 12%.

Net pay. 10,000 − 1,371 − 776.61 − 705 = PLN 7,147.39.

Employer cost. Pension 9.76% = PLN 976.00, disability 6.5% = PLN 650.00, accident 1.67% = PLN 167.00, FP and FS 2.45% = PLN 245.00, FGŚP 0.10% = PLN 10.00. Total PLN 2,048.00, so the full cost is PLN 12,048.00. The company pays ZUS (both shares plus health) by the 15th and the PIT advance by the 20th of the next month.

Example 2: The month cumulative income crosses PLN 120,000

Same employer and facts, but pay is PLN 20,000 gross every month. Employee social contributions are 13.71% = PLN 2,742.00 a month. Annual pay is PLN 240,000, still under the PLN 282,600 cap, so contributions do not stop.

Monthly income. 20,000 − 250 − 2,742 = PLN 17,008. Cumulative after July: 7 x 17,008 = PLN 119,056. After August: PLN 136,064. So August is the crossing month (PIT Act art. 32(2)(2)).

July advance (12%). 17,008 x 12% = 2,040.96, less 300 = PLN 1,740.96, rounded to PLN 1,741.

August advance (split). The first 120,000 − 119,056 = PLN 944 at 12% is PLN 113.28. The other 17,008 − 944 = PLN 16,064 at 32% is PLN 5,140.48. Total 5,253.76, less 300 = PLN 4,953.76, rounded to PLN 4,954.

From September (32%). 17,008 x 32% = 5,442.56, less 300 = PLN 5,142.56, rounded to PLN 5,143. The PIT-2 reduction still applies in 32% months (art. 31b(1) covers all advances under art. 32).

August net pay. Health is (20,000 − 2,742) x 9% = PLN 1,553.22. Net is 20,000 − 2,742 − 1,553.22 − 4,954 = PLN 10,750.78, against PLN 13,963.78 in July. The difference is the higher advance only.

The advances are only prepayments. If the employee has other income or reliefs (joint filing, child relief), the PIT-37 return settles the year; see pl-income-tax.

Ask the client first

  1. Is the employer a company or other legal person (ZUS due by the 15th) or an individual or partnership (by the 20th)? How many people did it insure for accident on average last year (9 or fewer means 1.67%)?
  2. Has the employee filed PIT-2 with this employer, or with up to two others (1/24 or 1/36 split)?
  3. Does the employee live outside the town of the workplace (PLN 300 costs), or is part of the pay for creative work under a contract that provides author's costs?
  4. Does the employee qualify for a relief: under 26, moved residence to Poland, four or more children, or past retirement age (60 women, 65 men) without drawing a pension?
  5. Is the employee in PPK, and at what rates?
  6. Does any of the work happen abroad, or is the employee covered by another country's social security with an A1?

Not yet confirmed: whether the employer's PPK payment is employment revenue of the employee under PIT Act art. 12(1), and in which month it arises (the PIT Act and PPK Act do not say so expressly; only secondary sources were found); the 2027 minimum wage (Dz.U. 2026 poz. 1213) is out of scope for this 2026 skill.
