If you made one or more errors in your turnover tax returns in 2021, you can correct this before 1 April 2022 with a supplementary return. You will then avoid having to pay 4% tax interest on the VAT still to be paid.
When supplementary declaration?
If you have already submitted your VAT return, you can only change the return if you make a correction of more than € 1,000 via a supplement. Smaller corrections can be settled with the next VAT return.
Pay attention! It concerns the amount to be refunded or paid on balance. For example, if you have declared € 1,600 too little VAT and deducted € 900 too little VAT, the difference is € 700. You can correct this via the next VAT return.
