Oops: you just filed your VAT submission and realized an invoice or expense is missing? Don't panic, you can easily submit a correction of your tax return. Here is what you can do.
Please note that you should not do this recklessly. A correction can always lead to a tax audit if the values differ greatly. If this is the case, please contact your tax coaches. We will be happy to help you with this.
1- Mark the VAT presubmission as 'not submitted' + 'not paid' to unlock the VAT period
From the taxes screen, simply click on the 3-dots menu of the tax item and select "mark as not submitted" + "mark as not paid", like shown below ⬇️
In case you also submitted a ZM (zusammenfassende Meldung) please mark the ZM also as "not submitted" right here:
2- Encode your income/expenses and assign them to the (now open for edit) VAT period
From the revenue/expenses screen, add or edit your documents.
In the "Additional information" section, assign the document to the required VAT quarter.
3- File the VAT presubmission again
The system has now recomputed the VAT presubmission, including the documents you have just added.
From the taxes screen, simply run the submission again.
This will send a correction to the Finanzamt.
