Request for an Extension of the Deadline for Submitting a Regular Tax Return

Main information

If you are a person who is required to submit a regular tax return for a tax with a taxable period of at least at least 12 months, you can request that the tax administrator extends the deadline for submitting the tax return. You can also request an extension of the deadline in certain specific cases, provided that the law does not exclude such extension (e.g. in certain cases of submitting a tax return for part of a taxable period).

If you wish to make use of both the statutory extension of the deadline for submitting an income tax return (to 4 or 6 months) and the extension on request, you must indicate this in your request.

If you submit your income tax return electronically, the statutory deadline is extended to 4 months after the end of the taxable period. 

If your income tax return is submitted by a tax advisor, or if you are legally required to have your financial statements audited, the statutory deadline for submitting the tax return is extended to 6 months after the end of the taxable period.

The tax administrator may extend the submission deadline by up to 3 months. If the tax base also includes income taxable abroad, the tax administrator may, in justified cases, extend the deadline up to 10 months after the end of the taxable period.

This applies to you if

You are a person who is required to submit a tax return for a tax with a taxable period of at least 12 months (or this is a specific case, such as a tax return for part of a taxable period where the law does not exclude an extension of the deadline) and you wish to extend the deadline for submitting the tax return.

Frequently asked questions

By when must the tax administrator decide on a request to extend the deadline for submitting a regular tax return?

If the tax administrator does not issue a decision within 30 days, the request is deemed approved. If the request is not granted and the decision to that effect is delivered after the expiry of the original statutory deadline for submitting the tax return, the period for submitting the tax return ends upon the expiry of the same number of days after the delivery of that decision as remained at the time the request for an extension was submitted before the expiry of the statutory submission deadline.
