A small update from us, maybe it will also give others hope who have the acceptance in the 2nd half of 2020
We are building with a general contractor, with 10 progress payments according to construction progress (x% after shell construction, x% after facade, x% after painting works, ...). Of these, 9 payments have already been invoiced and paid with 19% VAT, only the final installment is still outstanding. Final acceptance is planned for August/September.
Since the performance date = acceptance falls into the period of 16% VAT, the total amount (contract sum net) will be taxed at 16% for us. The difference, i.e. what we have "overpaid" on the previous installments, will be deducted from the final invoice. This means it will be only half as high as expected, saving around €10,000
