What Makes a Valid Tax Invoice?
A tax invoice must contain specific information to be accepted by tax authorities. Here's what every tax invoice needs:
- Seller's name, address, and tax ID — your business identity and tax registration
- Buyer's name and address — the recipient of goods or services
- Unique invoice number — sequential numbering for audit trails
- Invoice date and due date — establishes the tax period
- Description of goods or services — what was sold or provided
- Quantity, unit price, and line totals — detailed breakdown
- Tax rate and tax amount — clearly separated from the subtotal
- Total amount including tax — the final payable amount
ZapInvoice includes all required fields pre-formatted. Simply fill in your details and download a tax-ready PDF.
