What is a Tax Invoice and What Information is Required?

If you operate your business in a country that imposes a Value Added Tax (VAT) or Goods and Services Tax (GST), a standard billing invoice is not enough. You must issue a formal Tax Invoice. This document is a legal requirement that enables your business customers to claim tax credits. Let's explore what details are mandatory on a tax invoice.

What Makes it a Tax Invoice?

A tax invoice must clearly show specific tax details so that tax authorities can trace the transaction:

• Explicit Label: The document must clearly display the term "Tax Invoice" (not just "Invoice").
• Tax Registration Numbers: The seller's tax identifier (e.g., VAT Registration Number, GSTIN, ABN) must be displayed prominently. If the invoice amount is large, the buyer's tax number is also often required.
• Breakdown of Tax Rates: For each itemized line, you must specify the rate of tax applied (e.g., 0%, 5%, 20%) and the exact tax amount charged.

Summary of Mandatory Columns

When preparing a tax invoice, ensure your summary section has three separate lines:

1. Subtotal: The total price of all items excluding VAT/GST.
2. Tax Amount: The sum of all VAT/GST applied across items.
3. Total Due: The final amount payable, which is the Subtotal plus the Tax Amount.
