Before you start

Passport and residence document, visa or EU registration certificate
PESEL, preferred by most banks
A Polish address
CEIDG registration and NIP, for a business account

Step-by-step

1
Choose on English-language service and multicurrency support
mBank, ING, Santander Bank Polska and Millennium have strong English apps and free currency sub-accounts. PKO BP and Pekao are larger but their branch service is effectively Polish-only.

Issue the trusted profile in the same session
Your bank can create your profil zaufany in minutes. It unlocks e-PIT, NFZ services and — since April 2026 — the MOS residence portal, so doing it now removes a dependency from the front of your immigration timeline.

Activate BLIK
Six-digit codes generated in the app for online payment, cardless ATM withdrawal and instant transfers by phone number. Near-universal in Poland and the reason you will carry almost no cash.

5
Open a EUR sub-account if you invoice abroad
Polish banks provide free currency sub-accounts with their own IBAN. Being paid into a PLN account from a euro-area client means the bank converts at its own spread, which is materially worse than converting when you choose to.

Open a business account before your first invoice
Sole traders report a business account to the tax authority, and only business accounts can appear on the Ministry of Finance whitelist. Personal accounts cannot.

Things most newcomers don’t know

Where you file your PIT is worth PLN 80 a month here, in cash.

The Bilet Metropolitalny cuts the 30-day zone A pass from PLN 199 to PLN 119 and the annual pass from PLN 1,589 to PLN 949, for anyone who lives in Poznań or one of nineteen partner communes and settles income tax with a tax office covering that area. You do not need meldunek — a Poznań address on the PIT form is sufficient — and the entitlement can be registered through the PEKA app. It is the clearest example in Poland of a city paying residents to declare themselves.

Your bank issues the digital identity your immigration filing depends on.

Since MOS became the only channel for residence applications in April 2026, the profil zaufany moved from convenience to prerequisite. In a voivodeship where the wait already runs close to a year, adding weeks at the front of the process because you had no digital identity is the most avoidable delay available.

For tax, your euro invoice is converted at the NBP rate — not the rate you got.

Polish law converts foreign-currency revenue at the National Bank of Poland average rate published on the last working day before the invoice date. Your actual conversion happens whenever your bank does it, at a different rate, and the difference is a taxable exchange gain or loss you record separately. Poznań contractors invoicing German clients across the A2 meet this at their first year-end.

A whitelisted business account is not optional if you invoice at scale.

Payments over PLN 15,000 must reach an account on the Ministry of Finance whitelist or the paying company loses its deduction and can be jointly liable for VAT. Personal accounts cannot be whitelisted, and the corporate and logistics clients that dominate this market check automatically.

Common mistakes to avoid

Filing your PIT outside the Poznań area and paying PLN 80 a month more for the same transport pass.
Delaying the trusted profile and blocking the MOS residence filing behind it.
Receiving euro payments into a PLN account and losing 2–4% to the bank's spread each time.
Invoicing Polish companies into a personal account that cannot be whitelisted.
Letting the residence document on file expire and having outgoing transfers frozen.
