Rate

How the math works

Add VAT (forward): gross = net × (1 + rate ÷ 100)

Extract VAT (reverse): net = gross ÷ (1 + rate ÷ 100)

Worked example at Oman's standard rate: net 100 × (1 + 5 ÷ 100) = 105.00 gross, of which 5.00 is VAT.

Rates are only half of it — what must appear on the invoice (tax numbers, rate per line, reverse-charge wording for cross-border B2B) is covered in the VAT & GST invoicing guide, and the free VAT invoice generator produces a compliant PDF.
