Submission deadlines for the tax return

 

Early request by the tax office

The tax office may request an earlier submission in individual cases. In this case, be sure to meet the individually set deadline to avoid late fees.

Application for deadline extension

If you cannot submit the return on time, apply for an extension before 31 July 2025. Approval is at the discretion of the tax office and should be well justified (e.g. illness, stay abroad, missing documents).

Consequences of missing the deadline

After the deadline, you will usually receive a reminder with a new submission date. If you still do not submit, fines and penalties may be imposed.

Deadline for voluntary submission

For a voluntary tax return (without obligation to submit), the deadline is 31 December 2028. However, early submission can lead to a faster tax refund.
