Quick guide

- Enter the relevant amount and tax percentage.
- Verify net plus tax equals total, then apply the rounding unit required by the local tax and invoicing rules.
CHECK

FAQ
Frequently asked
Is 10% of a tax-inclusive total the VAT amount?
No. At a 10% rate, divide the inclusive total by 1.1 to get the net amount and take the difference as tax. Multiplying the inclusive total by 10% overstates it.
