GST & VAT invoice requirements
Essential fields for tax-compliant invoices in common jurisdictions.
Tax-compliant invoices require specific fields — business name, tax registration number, tax rate breakdown, and sequential numbering. Missing fields can invalidate input tax credits for your client.
InvoyFlow tax profiles let you set default rates and labels (GST, VAT, HST) and show tax breakdowns on every invoice.
Step by step
Register for tax if required
Obtain your GST, VAT, or HST registration number before charging tax.

Break down tax per line or subtotal
Show rate and amount separately.
Use sequential invoice numbers
Required for audit trails in most jurisdictions.
Keep records
Store invoices for the required retention period (often 5–7 years).
Do US businesses need VAT?
US businesses charge sales tax (state/local), not VAT. Rules vary by state and nexus.
