The tax refund is, for many, the nicest deposit of the year, and the timing is actually something you can influence. It is not about luck, but about when and how you approve your tax return. Do the right things in the right order and the money can land as early as April; do nothing at all and it drags into summer. And if you get residual tax instead, there are a couple of dates worth knowing so it does not start costing interest.
The tax return is available in the e-service from mid-March. If you approve it digitally by 31 March without changing or adding anything, you can get the refund as early as 7 to 10 April, provided you have registered a bank account. If you make changes or wait until the deadline in early May, the money is delayed to June. If you get residual tax it is interest-free up to 30 000 kr; above that a cost interest starts ticking, so then it pays to pay in early.
I will cover the key dates for the 2026 tax return, how to get the refund fastest, why you get money back or have to pay at all, and what applies with residual tax. To see whether you can expect money back, calculate in the tax return helper.
Key dates 2026
Keep track of four milestones. If you have a digital mailbox you get the tax return there around 2 to 6 March; the last day to get a digital mailbox to avoid paper post is 1 March. The e-service at the Tax Agency itself opens on 17 March, and you do not need to have received your tax return to start. If you approve by 31 March you can get the refund 7 to 10 April. The final day to file the tax return is 4 May, and those who file then get any money in June instead.
How to get the money fastest
Three things decide it. First: register a bank account with the Tax Agency in advance, otherwise the refund is paid via a payment notice that takes longer and needs extra steps. Second: approve the tax return digitally early, by 31 March, so you land in the first payout round in April. Third: do not change or add anything. The moment you make a change, for example adding a deduction, the tax return goes into a later pile for manual handling and the early April refund disappears. If you have deductions to make it can still be worth waiting for the money; a deduction worth more than an early payout is obviously better.
Why you get money back or have to pay
A refund or residual tax is not a reward or punishment, just a reconciliation. During the year your employer withholds preliminary tax from your salary, a standardised advance. When the year ends the Tax Agency works out your final tax, and the difference is either money back or residual tax to pay. If you get money back you paid in too much during the year, often because you had deductions or several employers; if you get residual tax too little was withheld, for example if you had side income or sold securities at a profit. So it is your own money all along, just correctly apportioned in the end.
If you get residual tax instead
If you get notice of residual tax, the most important thing to know is that it can start costing interest. Residual tax up to 30 000 kr is interest-free if you pay on time, but on amounts above that a cost interest runs that starts ticking even before the final payment day. If you have large amounts, for example after a property or share sale, it can pay to make a voluntary early payment to stop the interest. The final tax statement itself, where everything is in black and white, comes a few weeks after you have approved the tax return.
My recommendation
If you want the money fast: register a bank account, log in and approve the tax return early, and touch nothing if it is correct. If you have deductions to make, prioritise the deduction over a few days' earlier payout; it is almost always worth more. And if you expect residual tax above the interest-free line, pay in on time so you avoid the interest. Check what you can expect, back or to pay, in the tax return helper, and for the whole walkthrough of the tax return itself there is the guide how to do your tax return.
