Definition
A tax invoice is a document a registered seller issues that itemizes a sale and clearly states the tax applied to it, such as VAT or GST. It lets the buyer claim any allowable tax credit and gives tax authorities a verifiable record of the transaction.
Typical required fields
Exact requirements vary by country, but a tax invoice usually includes:
- The words "tax invoice" and a unique sequential number.
- Seller name, address, and tax registration number.
- Buyer details, the invoice date, and a description of goods or services.
- The net amount, tax rate, tax amount, and gross total.
Tax invoice vs other invoices
A simplified invoice is a shorter version allowed for small-value sales; it may omit full buyer details and show tax-inclusive totals. A regular (commercial) invoice requests payment but need not meet the formal tax-documentation rules. A tax invoice is stricter because it must satisfy local tax law so the buyer can reclaim input tax.
Because rules differ by jurisdiction, always confirm the fields your country mandates.
