If your company submits a declaration to be paid outside the deadline without prior request, you will have to pay a surcharge for late submission. This surcharge varies depending on the delay in declaring. Specifically:

• The surcharge will be 1%, plus an additional 1% for each full month of delay, if declared within the following 12 months.

• If the declaration occurs after 12 months, the surcharge is 15%. Additionally, you will have to pay late interest.

In these cases, there may be doubts about what is considered a “full month” and from what dates the surcharge percentages increase. Well, know that the deadlines in months must be calculated from date to date. That is, the surcharge percentage will remain constant until the day of the following month that has the same ordinal number as the day on which the deadline for declaring expired (and if that day does not exist, until the last day of that month).

For example, if your company forgets to submit the VAT for the second quarter of 2026, which has a deadline that ends on July 20:

• If you submit the declaration by August 20,2026, the surcharge will be only 1%; however, if you do it the next day —August 21—, it will be 2%.

• If you submit it on July 20,2027, the surcharge will be 12%.

• And if you do it on July 21,2027, or later, it will be 15% plus late interest.
