You've found the apartment, agreed the contract, and the landlord is waiting for money: the deposit (kaucja) — a median of about 5 000 zł in Warsaw (Passflat tenant data, August 2026) — plus the first month's rent. Eight or nine thousand złoty that must change hands before you move in. And here's the trap: the money is due now, but you have no Polish account yet — no PESEL, no bank visit behind you, and a transfer from your home bank is expensive, slow, or simply impossible.
The good news: this is solvable in a few days. The catch: the right path depends on your legal status, and there is no universal "just get Wise" answer.
Three scenarios: what actually works for your status
- You have UKR status, a karta pobytu, or a national D visa. Wise or Revolut will most likely verify you without trouble. This is the fastest first-week option: a working account in a day or two, no PESEL, no branch visit.
- You arrived recently and don't yet have a document confirming legal stay — a common situation for citizens of Belarus or Russia in their first weeks. Let's be blunt: Wise and Revolut verification often fails in this case — EEA-residency requirements were tightened in December 2025. Your realistic path: pay the kaucja in cash against a signed receipt (pokwitowanie), or with your home bank's card if it works in Poland, then open a Polish account in a branch as soon as you have a PESEL or meldunek.
- You want a Polish bank straight away. Online applications with selfie verification often stumble on foreign passports. The reliable route is a branch: with a passport (plus karta pobytu if you have one) they'll open the account in person — at some banks even without a PESEL.
Requirements shift every few months — check the current terms on the bank's website before any step.
Wise: an account in a couple of days — if it verifies you
If your status lets you pass verification (a document confirming legal stay plus a selfie), Wise (partner link — the service earns a commission; your terms don't change) covers almost the entire first month:
- You top up by card or by transfer from your home bank and hold the money in złoty — conversion at the mid-market rate with a transparent fee, and Wise gives you account details for receiving transfers.
- You send the kaucja and rent as an ordinary bank transfer to the landlord's Polish account — within Poland it usually arrives the same day.
- In the transfer title you write "kaucja", the address, and the date — leaving a paper trail, which matters more than it seems (more below).
There's one real limitation: Wise is a bridge, not a replacement for a Polish bank. For salary, utility settlements, and everyday life you'll still need a Polish account — you just get to open it calmly instead of in a panic.
A Polish account: two banks with live new-client bonuses
Since you'll need a Polish account anyway, pick a bank that's used to foreign passports and happens to pay new clients on top. As of August 2026, two have active welcome promotions — these aren't "the best banks in Poland forever", just practical picks with working conditions. Both accounts are free with basic use.
mBank — eKonto
Open an eKonto at mBank (partner link — the service earns a commission; your terms don't change).
The terms, honestly: new mBank clients only, and the bonus requires spending 200 zł by card or BLIK before the end of the first full calendar month after opening. For someone who's just moving in, that takes care of itself — a first Biedronka run and a transit pass cover it. mBank is also one of the banks that genuinely open accounts in a branch on a foreign passport, including without a PESEL.
Bank Millennium — Konto 360°
Open a Konto 360° at Bank Millennium (partner link — the service earns a commission; your terms don't change).
Also new clients only: within 10 days of opening, the account needs an inflow of 1 000 zł and at least one card or BLIK transaction. If you're moving your living money to Poland anyway, one transfer and one shop close both conditions.
Banks change promotion rules regularly — check the current version on the bank's website before opening.
Opening an account in a branch: what to bring and how long it takes
Why a branch? An online application with a selfie is an automated document check trained mostly on Polish IDs. It often fails to read a foreign passport: the application hangs "in verification" or gets rejected with no explanation. In a branch, a human looks at your document instead.
What to bring:
- Your passport — the core document; at most banks it's enough.
- Karta pobytu or visa, if you have one — removes almost every question.
- PESEL, if already issued — with it, the account opens in 30–60 minutes; without it, opening is still possible, but the procedure takes longer and not every branch is used to it.
- Your rental contract — sometimes requested as proof of address.
Typical timeline: with a PESEL — account, card in the app, and working BLIK the same day; without one — anywhere from an hour to a couple of days. Practice varies between branches: if one turns you down, try another branch or another bank — that's normal, not a sign you're "not eligible".
The kaucja: how to hand over money you'll want back
Whatever method you use, the rule is the same: whenever possible, pay by bank transfer. A transfer is evidence in itself: amount, date, recipient. In the transfer title, put "kaucja za mieszkanie", the apartment's address, and the date.
If a transfer is impossible and you pay cash — only against a receipt (pokwitowanie): amount, date, address, the word "kaucja", and both signatures. Without paper, getting the deposit back turns into your word against theirs.
Getting it back is realistic, by the way: 77% of Warsaw tenants who moved out recovered their deposit in full (Passflat tenant data, August 2026). How to end up among those 77% is covered in our deposit guide, and what to check in the contract before any money moves — in the rental contract checklist.
How much to have ready for the first month
Count the full move-in cost, not just the rent: a deposit of around 5 000 zł at the median, plus the first month's rent, plus — on top of rent — Warsaw tenants pay a median of about 800 zł more per month in czynsz administracyjny, utilities, and settlements (Passflat tenant data, August 2026). For a typical apartment that means 10–12 thousand złoty in the first weeks. The full price picture by district is in our Warsaw rent price report.
One last thing. Before you transfer five thousand złoty to anyone, check the building's address — tenants may already have shared real costs and deposit-return experience for that exact building. And once the first bills arrive, add your own costs: two minutes, no account needed, and the next newcomer will have it easier than you did.
