Apply for an extended deadline for submitting the tax return

If you’re having trouble meeting the deadline, you can apply for an extension. You cannot apply after the deadline has expired, so make sure you apply early if this applies to you.

The following may be granted an extended deadline:

  • income recipients and pensioners
  • self-employed persons and businesses
  • share owners in businesses assessed as a partnership
  • foreign businesses with a permanent place of business in Norway (branch)

You can apply for one month’s extension. We do not grant longer extensions.

If you’re self-employed or a business and do not submit the tax return or apply for an extension by the deadline, you may have to pay additional tax or an enforcement fine.

Apply by the submission deadline

You cannot apply for an extension after the deadline, so make sure you apply early.

30 April

  • income recipients
  • pensioners

31 May

  • sole proprietorships and companies
  • share owners in businesses assessed as a partnership
  • foreign businesses with a permanent place of business in Norway (branch)

Apply for an extended deadline

Online applications are granted automatically.

If you're unable to send the application online, you must send us a letter requesting an extension of the deadline. Send the application by post to:

Skatteetaten
Postboks 9200 Grønland
0134 OSLO

Applications that are submitted on paper will take longer to process.

If your spouse is running a business or is a self-employed person, you have the same submission deadline as your spouse

If one of the spouses applies for an extension and it is granted, the other spouse will automatically get the same deadline.

Important information

This year, some groups of businesses have received an automatically extended deadline. This only applies to the tax return for the 2023 income year that you submit in 2024.

An extension may result in you getting your tax assessment notice later

If you apply for an extension, you may get your tax assessment notice later. 

Unfortunately, we cannot give you a specific date for when you’ll receive your tax assessment notice. You’ll be notified.
