About Free GST Invoice Generator India
Create professional GST-compliant tax invoices with automatic GST calculation (5%, 12%, 18%, 28%). Add company logo, GSTIN, bank details, and multiple line items with HSN/SAC codes. Download as print-ready PDF. No account required.
A GST-compliant tax invoice in India must include specific mandatory fields — GSTIN of both parties (where applicable), invoice number and date, HSN/SAC codes, a breakdown of taxable value, and the correct GST rate and amount split by CGST/SGST or IGST depending on whether the transaction is intra-state or inter-state — and missing any of these can create compliance issues or make an invoice unacceptable for the recipient's input tax credit claim. Freelancers, small businesses, and consultants generating invoices without accounting software often get this structure wrong, particularly the CGST/SGST versus IGST distinction. This tool auto-calculates GST at the correct slab (5%, 12%, 18%, or 28%) and generates a properly structured, downloadable invoice with all required fields in place.

The format follows GST invoice rules under CGST Act. For legal and ITC purposes, ensure your GSTIN is active and all mandatory fields are filled correctly.
