If you were unable to meet the new submission deadline of the 1st or 2nd of November 2021, you could face late payment penalties of up to 10 percent. But don’t worry! As a rule, the tax office does not mind if the tax return is submitted a few days or a week later. If you need more time, send an informal letter requesting an extension of the deadline. This is usually enough to postpone the submission deadline. Our sample letter will help you!
