How This Is Calculated
A valid GST tax invoice must include specific mandatory fields: supplier and recipient names, addresses and GSTINs (where registered), a sequential invoice number and date, HSN/SAC code, description and value of goods/services, applicable GST rate and amount (CGST+SGST or IGST), place of supply, and whether reverse charge applies. This tool generates a compliant invoice format covering these mandatory fields.
Frequently Asked Questions
What fields are mandatory on a GST invoice?
▼
Supplier and recipient details (name, address, GSTIN), a unique sequential invoice number, invoice date, HSN/SAC code, description and taxable value of goods/services, GST rate and amount split by tax type, place of supply, and whether the transaction is under reverse charge.
Do I need to mention HSN/SAC codes on every invoice?
▼
HSN/SAC code disclosure requirements depend on annual turnover — businesses above certain turnover thresholds must disclose HSN/SAC codes at increasing levels of digit-detail on invoices; smaller businesses may have relaxed requirements. Check current CBIC notifications for the exact turnover-linked thresholds.
What is the difference between a tax invoice and a bill of supply?
▼
A tax invoice is issued for taxable supplies and shows GST separately. A bill of supply is issued instead when the supplier is not eligible to charge GST — for example, if registered under the GST composition scheme, or for exempt/nil-rated supplies — and does not show any tax amount.
Source and review trail
Use the current official instrument, portal or regulator publication before acting.
Scope: Generates a GST-compliant tax invoice and checks it against the mandatory particulars prescribed under Rule 46 of the CGST Rules.
Calculation logic
Populate the invoice with the mandatory Rule 46 particulars: supplier name/address/GSTIN, a consecutive serial number, date of issue, recipient details (name, address, GSTIN or, for unregistered recipients above the prescribed value, name and address), HSN/SAC code, description, quantity, value, tax rate and amount (CGST/SGST/IGST as applicable) and place of supply (for inter-state supplies).
For a registered person under the e-invoicing mandate, flag that the invoice additionally requires IRN and QR code generation via the Invoice Registration Portal for it to be a valid tax invoice — this generator produces the base invoice format, which then needs IRP registration where e-invoicing applies.
Inputs and assumptions
Mandatory-particulars checklist follows the current Rule 46 requirements; certain relaxations apply for specific invoice value thresholds or recipient categories (e.g., simplified requirements for invoices below a prescribed value to unregistered recipients).
Invoice numbering must be consecutive and unique for the financial year per Rule 46(b) — the generator flags this requirement but relies on the user's own sequential numbering.
Exclusions and edge cases
Does not itself submit the invoice to the Invoice Registration Portal for e-invoicing — where e-invoicing is mandatory for the taxpayer (see the E-Invoice Applicability Checker), IRN/QR code generation must be completed separately for the invoice to be legally valid.
Export invoices and invoices under specific schemes (e.g., bill of supply for exempt/composition supplies) have distinct format requirements not covered by this standard tax-invoice generator.
