1. Wrong VAT return filing because of an error with the data:

• If you have declared too much or too little VAT in a VAT return and if it turns out that you will receive or have to pay € 1,000 or less back for the period in question, then you do not need to submit a supplementary declaration. You may then settle this in the next tax return.
• This applies to corrections for this year (2021) and also for corrections for the past five years.
•  The error must then be processed with the question of the VAT return where the amount should have been declared.
• If you submit the supplementary declaration on time, you can only be imposed a default fine of 5% of the VAT amount due for non-payment or late payment of the VAT due, with a maximum of € 5,514. You do not owe a default penalty if: 

• the VAT amount to be paid according to the supplementary declaration is € 20,000 or less; or/and
• the amount to be paid for the supplement is less than 10% of the amount of the tax previously paid on balance or received back over the period(s) to which the supplement(s) relates.

2. Wrong VAT return filing done with the purpose of hiding transactions or similar:

• The negligence fine can amount to 100% on the tax that you still have to pay.
