Invoice errors can become costly for tax purposes, especially when VAT is shown incorrectly or required details are missing. Corrections should be traceable and refer clearly to the original invoice.
Typical invoice errors include wrong tax rates, incorrect VAT shown, reverse-charge mistakes, or missing required details. These defects can affect both the issuer and the recipient.
Check tax rate and exemption before sending
Do not mix reverse charge with regular VAT
Keep name, address, and service date complete
The right and duty to correct an invoice lies with the invoice issuer. One-sided changes by the recipient do not have tax effect.
Ask the invoice issuer to correct the document
Do not only overwrite changes internally
Document communication about the correction
A correction can be made through a separate correction note or through a new corrected invoice. If the original invoice number is reused, it should be clear that the document is a corrected invoice.
