PIT-11, PIT-37 and IFT-1R belong to the same annual tax workflow, but they are not interchangeable. The employer or another payer prepares PIT-11 or, for certain non-resident payments, IFT-1R. The individual files PIT-37 only when that return matches their situation.
Three forms in one workflow
- PIT-11 — annual named information from a payer about income settled mainly under the tax scale, costs, advances and selected contribution or relief data.
- PIT-37 — the taxpayer’s annual return, commonly used when tax on Polish income was calculated and withheld by payers.
- IFT-1R — annual information for a non-resident individual about specified Polish-source income covered by the relevant withholding rules or treaty treatment.
What does the employer report in PIT-11?
PIT-11 is not the employee’s tax return. It summarises amounts reported by the payer for the year: revenue and income, tax-deductible costs, advances collected, selected social and health contribution data, and items such as statutory exemptions when the form requires them.
Typical PIT-11 recipients include employees and people paid under civil-law arrangements when the relevant income is settled through payer advances. One person may receive several PIT-11 forms from different employers or principals.
PIT-11 and IFT-1R deadlines for the payer
- PIT-11: submit electronically to the tax office by the end of January following the tax year; give the taxpayer a copy by the end of February.
- IFT-1R: send to the competent tax office and the non-resident by the end of February.
- If the final day falls on a Saturday or public holiday, the deadline moves to the next working day. A payer that ceases business files the required information by the cessation date.
Information sent to the tax office must be electronic. Use the current form version, sign it with an accepted method and download the UPO official receipt. UPO proves technical delivery; it does not confirm that payroll data or tax classification were correct.
The employee copy may be provided through a payroll portal, secure email, post or in person under the organisation’s procedure. Protect tax and identity data, keep proof of availability or delivery, and do not use an unverified personal address.
Employer year-end checklist
- Classify every contract, payment type and period before year-end.
- Confirm tax residence facts and obtain a valid certificate of residence where treaty treatment requires it.
- Validate PESEL or NIP, name and current address; do not use placeholder identifiers.
- Reconcile payroll, benefits, costs, advances, contributions and exemptions against the general ledger and payment records.
- Select the current form, e-file it, verify acceptance and retain UPO.
- Deliver the individual copy securely and keep evidence.
- Correct discrepancies promptly and tell the person if the change may affect their annual return.
Do not merge data merely because the recipient is the same person. Separate payers issue separate information, and different income categories or residence periods may require both PIT-11 and IFT-1R.
PESEL, NIP and address are not cosmetic fields
Use PESEL for an individual who does not conduct business, is not a registered VAT taxpayer and is not a payer of taxes or social-security contributions. Use NIP when the statutory criteria for NIP apply. Incorrect identification can block electronic filing or prevent the information from appearing correctly in Twój e-PIT.
PIT-37 is the individual’s return
PIT-37 is commonly used by a person who received income taxed under the scale through Polish payers — for example employment or many civil-law payments — and who does not have circumstances that require PIT-36 or another return.
Business income, certain foreign income, income requiring self-calculated advances or another special source may lead to PIT-36 or a different form. Receiving PIT-11 is therefore strong input for the return, not a guarantee that PIT-37 is the only correct filing.
The employer does not file PIT-37 for the employee. It provides correct payer information; the taxpayer combines all relevant data, chooses reliefs or joint filing where available, and settles any tax due or refund.
How Twój e-PIT changes the process
- From 15 February, open Twój e-PIT in the e-Tax Office and compare the pre-filled amounts with every PIT-11 and other information.
- Add or correct reliefs, joint filing, public-benefit organisation data, bank account and any income not included automatically.
- Accept and submit the return by 30 April, or use another permitted filing method.
If a pre-filled PIT-37 is neither accepted nor rejected by 30 April, it is generally accepted automatically. That does not make every amount correct, and other return types are not automatically submitted on the same basis. The taxpayer can correct an accepted return when necessary.
Several PIT-11 forms mean one combined return
A change of employer or simultaneous contracts often produces more than one PIT-11. The taxpayer normally aggregates the relevant amounts in one annual return; filing a separate PIT-37 for each payer would be incorrect.
IFT-1 and IFT-1R are not the same document
IFT-1 is information prepared during the year, generally within 14 days after a non-resident’s written request. IFT-1R is the annual information prepared after year-end. Issuing IFT-1 on request does not remove the payer’s annual IFT-1R obligation when that obligation applies.
IFT-1R may cover specified Polish-source payments to a non-resident that fall under the withholding rules for particular services, rights, functions, capital income or other statutory categories. It may also be required when a treaty or statute results in no tax being collected.
When should a payer consider IFT-1R?
Start with the legal nature of the payment, the recipient’s residence status, the Polish source rule, the applicable tax provision and the double-tax treaty. Where treaty treatment is claimed, verify whether a current certificate of residence is required and whether the factual conditions are met.
Tax residence is more than the 183-day test
Under Polish domestic rules, a person may be Polish tax-resident if they have their centre of personal or economic interests in Poland or stay in Poland for more than 183 days in the tax year. A double-tax treaty can modify the result through its residence tie-breaker.
Citizenship, visa type and the number of days alone do not decide the tax form. Document the family, home, economic links, duration of stay and treaty position; reassess when the person’s circumstances change during the year.
Does IFT-1R mean there is no PIT-37?
Not automatically. For many payments taxed at final withholding, the non-resident may have no Polish annual return for that income. In other situations, the full facts can require PIT-36, PIT-37 or another settlement. Determine the answer from the income category, residence, withholding method and treaty — not from the heading of IFT-1R.
Corrections require action by both sides
- Payer: correct the PIT-11 or IFT information electronically, obtain a new UPO, deliver the corrected copy and explain which figures changed.
- Taxpayer: compare the correction with the return already filed and submit a separate corrected annual return if the change affects it.
- Control: retain the calculation, source documents, delivery evidence and reason for the correction.
What if the employee receives no PIT-11?
Missing PIT-11 does not remove the taxpayer’s filing obligation. The person should contact the payer, use contracts, payslips, bank transfers and other records to file on time, and correct the return later if confirmed data differ.
Late or incorrect information creates real compliance risk
Failure to prepare, submit or deliver required information — or providing unreliable data — may trigger fiscal-penal liability depending on the facts and fault. Act promptly, correct the information and document the response; do not promise that a payment or a generic voluntary disclosure automatically closes every risk.
A simple annual calendar
- December: close data gaps, residence evidence and payroll reconciliations.
- January: e-file PIT-11 and retain UPO.
- February: deliver PIT-11 to individuals, file and deliver IFT-1R, and review Twój e-PIT from 15 February.
- By 30 April: individuals file or verify their annual returns.
- After filing: monitor rejections, corrections and employee questions.
