Handle VAT differences on purchase invoices

Adjust small VAT rounding differences so the posted invoice matches the supplier’s VAT exactly.

Small VAT rounding differences are common. They usually come from different rounding rules.

Before you start

This feature requires setup in Business Central.

1. Search for General Ledger Setup.
2. Check these fields:

   • Allow VAT Difference
   • Max. VAT Difference Allowed

If these fields aren’t enabled, you won’t be able to post VAT differences.

Adjust the VAT on a purchase invoice

1. Open the Purchase Invoice.
2. Confirm the lines and VAT setup are correct.
3. Open Statistics.
4. Open the VAT details (this may be shown as VAT Amount Lines).
5. Enter the small adjustment in VAT Difference (or the editable VAT amount field).
6. Close the VAT details.
7. Post the invoice.

Keep VAT differences small.

If you frequently see larger differences, review VAT posting setup.
