Invoice types
Tax invoice
A tax invoice is an invoice that separately states the tax charged on a sale (such as GST, VAT, or sales tax), so a registered buyer can claim the tax as a credit.
What a tax invoice is
A tax invoice breaks out the tax portion of a sale rather than burying it in the total. In countries with GST or VAT, a valid tax invoice is the document a registered business needs to reclaim the tax it paid on purchases (input tax credit). In the US, the equivalent is an invoice that clearly itemizes sales tax.
Because tax authorities rely on it, a tax invoice usually has stricter content requirements than a basic invoice.
What a tax invoice must include
Beyond the usual invoice fields, a tax invoice typically shows the seller’s tax registration number, the words "Tax Invoice" where required, the tax rate and amount per line or in total, and the pre-tax and post-tax totals.
Exact requirements vary by country and tax system, so registered businesses should follow their local rules to keep invoices compliant and claimable.
Example: An invoice lists $1,000 in services, then "Sales tax (8%): $80," for a $1,080 total. Showing the tax separately makes it a tax invoice the buyer can record and, where applicable, reclaim.

Frequently asked questions
What’s the difference between a tax invoice and a regular invoice?
A tax invoice separately states the tax charged and includes the seller’s tax registration details, so registered buyers can claim a tax credit. A basic invoice may not break out tax at all.
Who needs to issue a tax invoice?
Businesses registered for GST/VAT (or that must collect sales tax) issue tax invoices so buyers have a compliant record. Requirements vary by country.
