Amending a return
Amend a filed Estonian KMD when paperwork arrives late: Arvello restates the full period from your corrected documents and generates fresh XML for EMTA.
Paperwork has a habit of turning up after the deadline. A supplier invoice arrives for a period you've already filed, a sale gets corrected or credited, or a tax code turns out to have been wrong. When the data behind a filed KMD (the Estonian VAT return) changes, you file an amended return for the same period — and Arvello builds it the same way it built the original.
When an amendment is needed
Once a return is approved, its period is locked: invoices and expenses dated inside it can't be edited, and trying produces the message "This period has a filed VAT return. Create an amendment to make changes." The lock is the point — the documents behind a filed return shouldn't drift quietly out of sync with what EMTA (the Estonian Tax and Customs Board) was told.
Typical reasons to amend:
- A purchase invoice arrived after the return was filed, and its input VAT is otherwise unclaimed
- A sales invoice was corrected or credited after filing
- A line had the wrong tax code, so an amount landed on the wrong KMD line — or on none at all
Creating the amendment
How amended figures relate to the original
An amendment is a complete restatement of the period, not a list of differences. It contains the full figures for every KMD line, recalculated from all the period's documents — original entries and late arrivals alike — so the newest filed return always stands on its own.
The original return isn't altered or deleted: it keeps its figures, its submission record and any e-MTA reference. The amendment carries an Amendment badge, a reference to the return it amends, and your reason. And if something changes yet again, a submitted amendment can itself be amended the same way.
