Filing a Swedish Tax Return as a Newcomer

Your first Swedish deklaration (tax return) is mostly filled in already. Your job is to check it, add what Skatteverket can’t know, and approve it on time. Here’s how to do that without BankID, what changes in your arrival year, and the 2026 rule changes that hit the 2027 return.

When you need this

• A deklaration just landed in your digital mailbox or post, and you moved here last year
• You don’t have BankID yet and need to approve or change the return
• You had pay, a pension or bank interest from your home country
• You commute far, live in two places for work, or bought cleaning or renovation services
• You moved to Sweden, or left, partway through the year
• You missed the deadline, or your final tax statement says you owe money

How the pre-filled return works

Sweden’s income tax return, inkomstdeklaration 1, comes pre-filled. Employers, banks and agencies report what they paid you, and Skatteverket (the Swedish Tax Agency) prints those figures in before you see it. If everything is right, filing takes one approval.

The deadline is set in law: 2 May of the year after the income year. If that day falls on a weekend, it moves to the next weekday. That’s why the 2026 deadline was 4 May, and why the 2027 deadline works out as Monday 3 May. Skatteverket publishes its own 2027 calendar early in the year, so check it then.

The year runs like this (dates from 2026, the latest published calendar):

Approving is declaring. The pre-filled return never contains foreign income. If you approve it as it is and leave something out, it’s still your statement, and an incorrect statement can cost a surcharge of 40% of the tax you would have avoided. Correcting it yourself, before Skatteverket asks, avoids the surcharge.

Who has to file

If you were registered and taxed as a resident for part of the year (your arrival year, typically), you must file once your taxable income reached just 100 kronor. Full-year residents file once their earned income reaches 42.3% of the prisbasbelopp (price base amount): 24,873 kronor for 2025 income, and about 25,040 kronor for 2026 income. Capital income of 200 kronor or more also triggers filing unless tax was already withheld on all of it. Foreign bank interest is the usual culprit.

The big exception is SINK, the flat tax for people living abroad who work in Sweden for at most six months. Once Skatteverket has decided SINK applies, you file no return for that income. Stay six months or more in a row and you’re taxed as a resident instead; see moving to Sweden for work for that line.

Filing without BankID

Many newcomers spend months waiting for a personnummer, an ID card and then BankID. You can still file:

So if you need to add foreign income and have no e-ID, the paper form is your route. The postal address is on the return and in the practical table below.

Your arrival or departure year

Swedish worldwide taxation starts on the day you arrive if you move here or stay six months or more in a row. From then on, the general rule is that you must declare income from every country: foreign pay, pensions, rental income and bank interest for the period you lived here. A tax treaty can exempt some of it, but you still report it.

The arrival year also changes your grundavdrag (basic allowance). If you were resident only part of the year, the law cuts it to one twelfth of 0.293 price base amounts per month or part-month. You keep the normal allowance if almost all your earned income worldwide that year was Swedish. That’s why someone who arrives in autumn with a year’s foreign salary can end up with a smaller allowance than a colleague who earned only in Sweden.

Leaving works in reverse, with a twist. You may still have to file a Swedish return after you move away. Swedish citizens and people who lived here at least ten years stay fully taxable for five years unless they show they no longer have an essential connection. And there’s a kind rule in the law: if you live abroad on deadline day, there’s no late fee as long as you file by 31 May.

The six-month test itself may change. A government bill proposes counting days per calendar year from 1 January 2027; digital nomads and remote workers covers it.

Deductions newcomers miss

Two 2026 changes affect the return you file in spring 2027.

Rut and rot usually need no action from you. The company takes the reduction off its invoice and reports it, so it normally appears pre-filled. Check it’s there.

If you run your own business with F-skatt (F-tax), you pay your own preliminary tax monthly and your business income ends up in the same annual return. The remote-work angle is in our digital nomads guide.

Refunds, residual tax and late fees

Refunds depend on timing. Approve digitally and unchanged by 31 March, and the refund lands in April. File by the May deadline and it normally comes in June; returns that need checking or have an extension get paid in August or December. The money only arrives automatically if you’ve registered a bank account. You can do that with e-ID in the tax account e-service, through Bankgirot without e-ID, or by post for a foreign account, which takes about four weeks. No account? The refund just sits in your skattekonto (tax account) until you ask for it. Our guide to coordination numbers and bank accounts helps if you have no Swedish account yet.

Residual tax (kvarskatt) is due by the date on your final tax statement, at least 90 days after the decision. If you’ll owe more than 30,000 kronor, interest runs from 13 February. Pay in by 12 February to avoid it; early payments avoid interest altogether.

Late filing costs a fixed 1,250 kronor, with a second and a third fee if the return is still missing three and five months after the deadline. Skatteverket can also set your tax on its own estimate.

Practical information

FAQ

When is the Swedish tax return due in 2027?

The law sets 2 May of the year after the income year. In 2027, 2 May is a Sunday, so the deadline moves to Monday 3 May under the general rule that weekend deadlines roll to the next weekday. Skatteverket publishes its own calendar for 2027 early in the year; in 2026 the deadline was 4 May.

Do I have to file a Swedish tax return in my first year?

Yes, if you were registered and taxed as a resident for part of the year and had at least 100 kronor of taxable income. Full-year residents file once earned income reaches 42.3% of the price base amount. If you only worked here under SINK, a flat tax for stays of up to six months, you do not file for that income.

Can I file my Swedish tax return without BankID?

Yes. If everything is correct you can approve the return by texting your personal identity number and code to 71144 from a Swedish mobile, by phone, or by posting the paper form. The e-service also accepts the security code printed on your return, but with it you can only add commuting costs, contact details and a bank account.

When will I get my Swedish tax refund?

Approve the return digitally and unchanged by 31 March and the refund is paid in April. File by the May deadline and it normally comes in June. Returns that need checking or have an extension are paid in August or December. The money only arrives automatically if a bank account is registered with Skatteverket.

Do I need to declare foreign income in Sweden?

If you are taxed as a resident, the general rule is that all income from every country must be declared, including foreign pay, pensions and bank interest for the period you lived here. The pre-filled return never includes it. A tax treaty or Swedish rules can exempt some income, but you still report it.

What happens if I file my Swedish tax return late?

You pay a late-filing fee of 1,250 kronor, and further fees if the return is still missing three and five months after the deadline. Skatteverket can also set your tax on its own estimate. If you live abroad on deadline day and file by 31 May, no fee is charged.

What can newcomers deduct on a Swedish tax return?

The most common are commuting costs above 15,000 kronor a year from income year 2026, double-residence and home-travel costs when you work away from your family home, and other work expenses above 5,000 kronor. Rot and rut reductions for renovation and household services normally appear pre-filled. Unsecured loan interest is no longer deductible.
