Reverse VAT expliqué

• When reverse VAT is useful
• What to check before relying on the result

Reverse VAT is useful when the number you have is already tax-inclusive. Common examples include supplier quotes, consumer-facing totals or imported figures from a billing system.

Instead of adding VAT to a net value, the reverse calculation splits the gross total into two pieces: the net base and the VAT amount.

The reverse calculation only works properly when the correct VAT rate is applied. If the product or service could qualify for a reduced rate, confirm that first.

It is also worth checking the country context because invoice wording, thresholds and VAT treatment can differ even when the math itself is straightforward.
