Rate

How the math works

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

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

Worked example at Singapore's standard rate: net 100 × (1 + 9 ÷ 100) = 109.00 gross, of which 9.00 is GST.

Issuing a GST-compliant invoice?

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. The full rate dataset behind this page (42 jurisdictions, source per row) is downloadable: CSV · JSON (CC BY 4.0).
