Moving to a new country is a mountain of admin, and most of it is not about money. This guide sticks to the money: how to get a bank account and BankID, how to start building a credit history, where to put your first savings, and what happens to it all if you move on. The logistics of visas and permits belong elsewhere; this is about making your money work while you are here.
Get a personnummer if you are staying, or a samordningsnummer (coordination number) if you are here temporarily; almost everything financial hangs off one of them and off BankID. Open a bank account as soon as you can, start an ISK for any long-term saving, and if you work here only part of the year, check whether SINK or ordinary tax is cheaper for you. If you leave, your pension comes with you.
I will go through the numbers and BankID, the first bank account, building credit from zero, the first ISK, the SINK question and what happens if you leave. Try your net pay in the salary calculator as you read.
Personnummer, coordination number and BankID
The key to everything is an identity number. If you are going to live and work here for at least a year you register with Skatteverket and get a personnummer. If you are here temporarily you get a coordination number (samordningsnummer) instead, which works for tax and salary but gives fewer rights. The next step is BankID: the digital ID that almost everything else requires, from logging in to the bank and Skatteverket to signing contracts and using Swish. You get BankID through your bank, so the order is usually number first, then bank account, then BankID. Expect it to take a few weeks; once it is in place, everything else goes much faster.
Your first bank account
Under EU rules everyone legally resident in the EU has the right to a basic payment account, even without a personnummer, so a bank cannot simply turn you away entirely. Bring valid ID and, ideally, proof of address and employment when you open the account. If a bank says no to a full account with a card and credit, you still have the right to a basic payment account, so do not give up at the first no. The money in the account is protected by the deposit guarantee up to a high amount, so it sits safely whichever bank you choose.
Swish, and what you do before you have it
Swish needs three things: a Swedish bank account, BankID, and a phone that can receive your bank's verification SMS. The number does not have to be Swedish, which few people seem to know: Swedbank, Handelsbanken, Nordea, Länsförsäkringar, SEB and Danske Bank will all connect a foreign mobile number. What actually breaks it is a foreign operator that will not pass the bank's SMS through.
The real blocker is BankID, which is built on the personnummer. A coordination number does not get you BankID, and therefore does not get you Swish, and there is no shortcut around that. So the order is personnummer, then account, then BankID, then Swish, and the waiting is all in the first step.
In the meantime you get further than you would think. The debit card from your payment account works in shops, in restaurants and tapped on public transport, which covers nearly everything. To pay a person, make an ordinary bank transfer with their clearing number and account number, and to be paid from abroad, give out your IBAN and your bank's BIC. Swish itself is then free to get, send and receive as a private individual, so waiting costs you nothing.
Building a credit history from zero
Your credit history from home does not follow you; in Sweden you start from zero. When you apply for a loan, a card or a subscription the lender runs a credit check, and early on there is little to go on. Being refused a card or a mortgage in the first years is common and nothing to take personally. You build a history by having an income, paying bills on time and not applying for lots of credit at once, since many enquiries in a short time look worrying. With time and a steady income the doors open on their own.
Your first ISK
Once you have a personnummer and a bank account, an investment savings account (ISK) is the simplest place for long-term saving. Instead of paying capital-gains tax every time you sell, you pay a low flat tax on the whole balance, and you avoid reporting each trade. Put the money in a few broad, cheap index funds and leave it alone. But take the buffer first: read the guide to your first emergency fund before you start investing, so you never have to sell at a bad time.
Say you set aside 2,000 kr a month in an ISK from your first year here. At around 7 percent average return that is roughly 345,000 kr after ten years, of which about 105,000 kr is pure growth you only paid a low flat tax on. Same amount, same time, but the money has had a chance to work for you. See how your own figure grows in the savings calculator.
SINK or ordinary tax
If you work in Sweden but still live abroad you can be taxed under SINK: a flat 22.5% in 2026 (20% from 2027) with no deductions, but also no tax return to file. If you are here longer and become resident (usually from six months) you are taxed like everyone else, with grundavdrag and jobbskatteavdrag, which is often lower but requires you to file a tax return. You are actually allowed to choose ordinary taxation even if you qualify for SINK, if it works out cheaper for you. If you are not sure which pays off, compare in the SINK calculator.
If you leave Sweden
The money does not disappear because you move. Your earned state pension and occupational pension are yours and are paid out wherever you live when you retire, anywhere in the world. You can usually keep an ISK, but ask your bank, and bear in mind you may become taxable in your new country instead. The most important practical step is to notify Skatteverket of the move, so your tax and registration are correct. Do it in time and you avoid unpleasant surprises much later.
My recommendation
When I picture arriving in a new country with all that paperwork, the money part is the bit that quietly decides how settled you feel. My advice is to take it in order: sort out the number and BankID, open an account, build a small buffer, then start an ISK and let it run. Do not stress about credit; it comes with time and a steady income. And keep the decisions simple, because the version of you who one day files a Swedish tax return, or moves on somewhere else, will thank you. Start with your net pay in the salary calculator and a first amount in the savings calculator.
