Pre-notify sales tax

What deadlines must be paid attention to?

This is a declaration or registration deadline.
You must submit the advance VAT returns by the 10th day after the end of the advance return period (month/quarter) at the latest.
Upon request, the tax office can extend the deadline for submitting the advance returns and for paying the advance payments by one month (permanent deadline extension).
If you submit monthly advance VAT returns, the granting of a permanent extension is dependent on you making a special advance payment.
