The deadline for uploading or correcting your data is by the 10th of the following month at the latest. For example, if you need to submit data for the month of June, the final deadline would be July 10th.
❗Should you upload the data after the deadline, it can indeed be corrected and reported. However, this requires VAT experts to regenerate the files and submit corrections to different tax authorities, which will incur additional charges.❗
