Denmark for Polish Expats: The Complete Relocation Guide

Denmark for Polish Expats: The Complete Relocation Guide

Poles are one of the largest immigrant groups in Denmark, so you are joining a well-established community — but the paperwork still has to be done in a specific order, and getting it wrong costs you weeks. The single most important thing to understand: nothing else works until you have a CPR number (your civil registration number). It unlocks your tax card, healthcare, bank account and MitID login. This guide walks the steps in the order Danish authorities actually expect them.

The good news for Polish citizens is that you have full EU rights. No visa, no work permit, no salary threshold, no job offer required to enter. Your residence registration is a formality, not an approval you can be refused.

Step 1: EU residence document (before three months are up)

For stays under three months you do not need to register at all. For stays over three months — which applies to almost anyone relocating — you apply for an EU residence document (EU-opholdsdokument) through SIRI (Styrelsen for International Rekruttering og Integration / Danish Agency for International Recruitment and Integration).

1. Complete the online application on nyidanmark.dk — workers use the "EU residence as a worker" route.
2. Book and attend a SIRI branch office in person within 14 days of submitting online (bring your passport/ID).
3. SIRI issues your residence document. It has no expiry date.

You need this document to get your CPR number, so do it first.

Step 2: CPR number, MitID and the yellow health card

You cannot apply for a CPR number until you have found a place to live and actually live there. Once you have a registered address, book an appointment at an International Citizen Service (ICS) centre — there are branches in Copenhagen, Aarhus, Odense, Aalborg and Sønderborg — or at your municipal Borgerservice if you live elsewhere. ICS is the better choice because tax, CPR and other authorities sit under one roof.

Bring your passport/ID, your EU residence document, and proof of address (tenancy contract). Processing takes about 2–3 weeks after you apply (lifeindenmark.borger.dk; check current times). Getting your CPR triggers three things:

• The yellow health insurance card (sundhedskort) is issued automatically when you register. It lists your assigned GP (læge) and is required for every doctor, dentist or hospital visit.
• MitID, Denmark's national digital login, which you set up once you have a CPR (you must be 13+ and meet ID requirements). MitID is mandatory for banking, tax and almost all public services.
• Access to apply for your tax card.

See the full CPR number walkthrough for document specifics and booking links.

Step 3: Tax card (skattekort) — do not skip this

The most expensive newcomer mistake is starting work without a digital tax card (skattekort). With no tax card, skat.dk requires your employer to deduct 55% of your salary. You can apply up to one month before your first working day, so there is no excuse to wait.

When you generate the card yourself, you enter your expected gross salary for the rest of the year and your first working day. Full detail in the tax card guide. If you still have Polish income in your moving year, you can report non-Danish income via E-tax to avoid double taxation under the Poland–Denmark treaty.

Step 4: Bank account and NemKonto

Every resident must assign a NemKonto — simply a normal Danish bank account designated to receive wages, tax refunds and any public payments. To open a Danish account you generally need your CPR number, MitID and ID. Compare options in the best bank accounts for expats guide.

While your Danish account is being set up — banks can take days to weeks to approve a newcomer — you still need to move money from Poland and pay for a deposit. Wise is popular with Polish expats here: you get real mid-market PLN→DKK rates and a multi-currency account without a Danish bank, which bridges the gap before your NemKonto is live. Keep your Polish account too; cross-border EU transfers in EUR/PLN remain simple.

The Polish community in Denmark

You are not arriving cold. Poles are one of Denmark's largest immigrant groups and among the top sources of foreign full-time employees, concentrated in Copenhagen, Aarhus, Odense and around agriculture, construction, logistics and healthcare. Practical anchors:

• Polish Catholic parishes in Copenhagen and Aarhus hold Polish-language Mass and act as informal community hubs.
• Polish weekend/Saturday schools (szkoła polonijna) keep children's Polish language and curriculum alive.
• Large Polish-language Facebook groups (e.g. "Polacy w Danii") for jobs, housing leads and second-hand furniture — useful but verify any housing offer in person.
• Polish grocery shelves are common in larger supermarkets and dedicated sklep polski shops in bigger cities.

Cost of living: what to budget

Denmark is more expensive than Poland across the board, and rent in Copenhagen is the biggest shock. Exact figures change, so treat any number as approximate and verify locally — but the relative gaps are real: housing, eating out and alcohol are markedly higher, while you receive tax-funded healthcare and (for residents) tuition-free public education. Your high gross salary is offset by income tax that typically runs from the high-30s to mid-40s percent and beyond once you include labour-market and municipal tax. Budget your net, not gross, and confirm your marginal rate on skat.dk.

Common problems and fixes

• "I can't open a bank account — they keep asking for CPR." Correct, and unavoidable. Sequence is fixed: residence document → address → CPR → MitID → bank. Use Wise for transfers in the meantime.
• My first payslip taxed me at 55%. Your tax card wasn't registered before payday. Apply via skat.dk/tastselv or form 04.063 immediately; overpaid tax is refunded once the card is active.
• No MitID yet, so I can't log in anywhere. MitID needs a CPR first. Until then, ICS staff can help with paperwork in person.
• Assigned a GP far from home. You can change your læge via your municipality/borger.dk once you have MitID (a small fee may apply).
• Denmark has no "digital nomad visa" — that route does not exist. As a Polish EU citizen you don't need one anyway; you register under EU free-movement rules.
• Address registration delayed because the landlord won't confirm. You cannot get CPR without a real registered address. Insist on a registrable tenancy contract before paying a deposit; informal sublets without registration rights are a common trap.

Your next step

Before anything else, confirm your housing gives you the right to register your address — then book your ICS appointment. Start by reading the CPR number guide and applying for your EU residence document on nyidanmark.dk this week, so the 2–3 week CPR processing clock starts as early as possible.
