If you miss paying a VAT return before the deadline, then a surcharge or penalty might be incurred. For some of the countries you will receive a reminder letter, but this can arrive too late already, as we speak of cross border tax offices and shipping.
You can check all your tax letters in the Tax Letter Inbox.
If the deadline has passed you will have to pay a penalty. Each country has different methods of calculating the penalty amounts.
We encourage you to pay the penalty before the deadlines written in this article.
