VAT CORRECTIONS (SUPPLETIE)
Correct a previous VAT return with Taxmo
Found a mistake in a VAT return you've already submitted? Use Taxmo to prepare a VAT correction, known in Dutch as a suppletie. Check what changed, update the relevant figures, and review your correction before submitting.


The basics

A correction starts with understanding the difference
A missing invoice, duplicate expense, or incorrect VAT treatment can affect a return you have already submitted. Before correcting it, you need a clear record of the original figure and the revised amount.
The appropriate correction process depends on the circumstances and current Belastingdienst rules.

What Taxmo users say
“
You rock and I've now signed up so you have me as a permanent client! I love the rapid turnaround; that you take care to actually read the question to understand what I am trying to do and orient your replies to be as helpful as possible to me. You put me first, as the client, and it shows. This kind of CX is very rare and it makes you stand out from the crowd. I think you do yourselves a disservice when you say you are AI powered - I think you are human powered, assisted by AI.
