A tax invoice is an invoice issued by a VAT or GST registered business that contains the details the tax authority requires, such as the seller's tax number, the tax rate and the tax amount, so the buyer can reclaim the tax.
In countries with VAT or GST, the buyer can usually only claim back the tax they paid if they hold a valid tax invoice. That is why the rules are strict: a missing registration number or tax amount can mean the client's accounts team rejects your invoice. The exact list differs by country, but most require the same core fields.
The VAT/GST template handles several tax rates on one invoice and summarises tax by rate. The GST India format adds GSTIN, HSN/SAC and the CGST, SGST or IGST split.
