What a GST tax invoice must contain
Rule 46 requires a consecutive serial number, the date, the supplier's name, address and GSTIN, the recipient's name, address and GSTIN (or state and state code for unregistered recipients above ₹50,000), the HSN or SAC code, description, quantity, taxable value, rate and amount of each tax, the place of supply, and a signature.
Invoices must be numbered in a continuous series for the financial year. Restarting a series mid-year or leaving gaps is a common audit finding.
Getting the tax split right
If the place of supply is in your own state, split the rate into CGST and SGST. If it crosses a state border, charge IGST at the full rate. For exports and SEZ supplies, either charge IGST and claim a refund, or supply under LUT with no tax and mark the invoice accordingly.
Businesses above the notified turnover threshold must also generate an Invoice Reference Number through the e-invoicing portal before the invoice is valid — a printed invoice without a valid IRN and QR code is treated as no invoice at all.
Frequently asked questions
Is this invoice legally valid?
It contains the fields required by Rule 46 of the CGST Rules. If your turnover crosses the e-invoicing threshold you must additionally register the invoice on the IRP portal to obtain an IRN and QR code.
Is my invoice data stored anywhere?
No. Everything is calculated in your browser and nothing is uploaded or saved on our servers.
How do I add HSN codes?
Each line has an HSN/SAC field. HSN reporting is mandatory at four digits for turnover up to ₹5 crore and six digits above that.
