The assessment periods are already time-barred, is the adjustment still possible?

Neither the VAT Act nor the application decree provide for a time frame for a VAT adjustment, i.e. in principle, bad debts from previous years can also be adjusted. As the correction is always made in the current assessment period by reducing the current sales revenue, it is generally irrelevant whether the VAT assessment in which the turnover to be corrected was originally reported can still be changed or not.
