Foreign workers & legalization
Tax data of a foreign national
For non-residents, Onboardly collects the data needed for the IFT-1/IFT-1R statement and for correct settlement depending on where the work is performed.
Settling a foreign national depends on where they have their tax residence and where they perform the work. For non-residents you collect the data needed for the IFT-1/IFT-1R statement — a personal statement of the income of a person who does not have unlimited tax liability in Poland.
Residence and place of work
Tax residence determines the country in which a person settles their total income. The place where the work is performed determines where the income is taxed. That is why you collect both of these elements in the employee's data.
Documents and forms
- Residence certificate — a certificate of tax residence issued by a foreign authority; it confirms where the person is a resident.
- A1 form — confirmation that the person is subject to social security in another country.
- Information under art. 29(1) of the Labor Code — written information on employment conditions for a person posted to work abroad.
Two situations
| Situation | What you determine |
|---|---|
| Work in Poland | Income taxed in Poland; you check residence and the basis for IFT-1/IFT-1R for a non-resident. |
| Work abroad | Place of taxation outside Poland; the A1 form and information under art. 29(1) of the Labor Code may be needed. |
Generating IFT-1/IFT-1R
From the data collected in the employee file, Onboardly generates the IFT-1/IFT-1R statement as a PDF — with the non-resident's personal data, foreign TIN, address, foreign bank account (IBAN + SWIFT/BIC), residence certificate, legalization documents with validity dates, and the total income and tax withheld for the selected year. The same data is available via the API: GET /api/v1/employees/{id}/ift — see the API documentation.
