What Must Be Included on a Valid Tax Invoice?
Tax authorities across jurisdictions (including HMRC in the UK, the GST Council in India, the ATO in Australia, and European revenue services) require specific mandatory fields for an invoice to qualify as a legal tax document for tax credit deductions:
1. Seller & Buyer Tax Identifiers
The legal name, registered trading address, and statutory tax number (VAT Number, GSTIN, or Tax ID) of the supplier. For B2B transactions over statutory thresholds, the customer’s tax ID must also be recorded.
2. Sequential Reference & Tax Point Date
A unique invoice identification number following an unbroken continuous sequence, along with the date of issue and the "tax point" (the date when supply took place or payment was made).
3. Itemized Tax Breakdown by Slab
For each line item: clear description, quantity, unit rate excluding tax, applicable tax rate percentage (e.g. 20% or 18%), and the resulting tax amount. If supplies are zero-rated or exempt, this must be explicitly noted.
Tax Calculation Reference
Standard statutory rates by region:
Inclusive vs. Exclusive Formula
Exclusive: Tax = Subtotal × (Rate / 100)
Inclusive: Tax = Total - (Total / (1 + Rate / 100))
Frequently Asked Questions
What is a tax invoice and how is it different from a regular invoice?+
A tax invoice is a legally mandated document issued by a tax-registered business to a customer. Unlike a regular commercial bill, a tax invoice must explicitly display the seller’s tax registration number (such as VAT ID, GSTIN, or ABN), the customer’s tax ID if applicable, a clear itemized breakdown of the tax rate applied to each good or service, and the separate net and gross totals.
Does this generator support both tax-inclusive and tax-exclusive pricing?+
Yes. With one click on our calculation mode toggle, you can switch between Exclusive (where tax is calculated on top of the subtotal) and Inclusive (where the item prices already include tax and the system calculates the embedded tax component using standard statutory rounding).
Can I split taxes into CGST and SGST for Indian GST invoices?+
Yes. Select the 18% GST preset or add custom tax slabs to split rates into CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax) for intra-state transactions, or IGST for inter-state supplies.
Can I print or download my tax invoice as a clean PDF without watermarks?+
Yes, 100%. All exported documents are clean, high-resolution vector PDFs free of any branding, advertisements, or watermarks. What you see in the live preview is exactly what renders in your PDF.
Is my client and financial tax data saved privately?+
All invoices are processed locally on your device in your web browser. Generate Real Invoice does not store your client details, tax identification numbers, or pricing data on any remote server.
