What a tax invoice must contain – supplier’s name, address and GSTIN, a serial number of not more than sixteen characters, date, recipient’s details, HSN code, description, quantity, value, taxable value, rate and amount of each tax, place of supply for inter-State supplies, whether reverse charge applies, and the signature. E-invoicing taxpayers must also print the QR code with the Invoice Reference Number.

What this means in practice

The parts that actually decide cases — the things a practitioner checks first.

1

HSN reporting: six digits where aggregate turnover exceeded Rs 5 crore in the previous year, four digits below that for B2B supplies. A wrong or missing HSN is a common late-fee and mismatch trigger.

2

The invoice number must be unique for the financial year and not exceed sixteen characters.
