Please note that your tax return cannot be changed via online submission (not by mail) once your ID has been validated.
If you choose to send it by mail and up to now, you have only sent the tax return to the tax office electronically, then we are able to re-release it for processing. We need the email address that you registered with and the tax year for this.
After making the changes, you can resubmit your tax return electronically using our tool. Please note that you will also send the hard copy of your declaration with the correct information to the tax office by post.
If you’ve already sent your tax return electronically and by post, you should contact your respective tax office and explain your situation to them.
