Extend tax return deadline
You must submit your tax returns including tax declarations to the responsible tax office by the legally prescribed deadline. If you are prevented from complying with the submission deadline, you can apply to the responsible tax office for an extension of the submission deadline. If the tax office passes your application, you can submit the tax return by the newly agreed deadline. If your tax returns are prepared by a tax consultant or income tax assistance association, longer deadlines apply to the submission of annual tax returns (with the exception of the income tax return). Therefore, in these cases, an extension of the deadline is only possible if you are or were unable to comply with the deadline through no fault of your own.
The application and, if applicable, documents proving the impediment.
Your application must state the reason why you are prevented from complying with the deadline.
