GST Invoice Generator (India) — Rule-46 Compliant
Under Rule 46 of the CGST Rules, every GST tax invoice must carry a fixed set of statutory fields before the buyer can claim input tax credit. Miss even one field and the invoice is defective — the recipient cannot treat the missing-field document as a valid tax invoice for ITC purposes. This generator validates and prints all Rule-46 mandatory fields, and automatically splits the tax line into CGST + SGST/UTGST (intra-state supply) or a single IGST (inter-state supply) based on the place of supply you enter. On ₹50,000 taxable at 18% GST: an intra-state supply shows CGST ₹4,500 + SGST ₹4,500 (total tax ₹9,000, invoice total ₹59,000); an inter-state supply shows IGST ₹9,000 — the total is identical, only the split differs. Fill in your supplier GSTIN, buyer details, HSN/SAC codes and line items, and download a compliant PDF in seconds — no login, no subscription.

- Worked example — ₹50,000 taxable @ 18% intra-state: CGST ₹4,500 + SGST ₹4,500 → ₹59,000
- Worked example — same ₹50,000 @ 18% inter-state: IGST ₹9,000 → ₹59,000 (same total)
Frequently asked questions
What must a GST tax invoice include under Rule 46?
Rule 46 of the CGST Rules requires: (1) supplier name, address and GSTIN; (2) a consecutive serial number unique for the financial year, not exceeding 16 characters; (3) the date of issue; (4) the recipient's name, address and GSTIN (if registered); (5) place of supply with State code for inter-state supplies; (6) HSN code (goods) or SAC code (services); (7) description of goods or services, quantity and unit; (8) the taxable value after any discount; (9) the applicable GST rate; (10) the amount of tax — CGST + SGST/UTGST for intra-state, or IGST for inter-state; (11) whether tax is payable on reverse-charge; and (12) the signature or digital signature of the supplier or an authorised representative. This generator emits all twelve printed fields.
CGST + SGST or IGST — which applies to my invoice?
The split is determined by the place of supply, not by where the buyer is located or registered. For an intra-state supply (supplier and place of supply in the same State), the GST splits equally: 18% becomes 9% CGST + 9% SGST/UTGST. For an inter-state supply (supplier and place of supply in different States, or an export), a single IGST is charged at the full rate (18%). The total tax — and therefore the invoice total — is identical either way. On ₹50,000 at 18%: intra-state gives CGST ₹4,500 + SGST ₹4,500 (total ₹9,000, invoice ₹59,000); inter-state gives IGST ₹9,000 (invoice ₹59,000). The generator switches the layout automatically from the place of supply you enter.
Does this generator register the invoice on the IRP or produce an IRN / QR code?
No. This is a stateless, printed-invoice generator. Businesses above the GST e-invoicing turnover threshold must separately register each B2B invoice on the Government Invoice Registration Portal (IRP), which returns an Invoice Reference Number (IRN) and a signed QR code that must be printed on the invoice. This tool produces the Rule-46 printed fields only — it does not connect to the IRP and does not generate an IRN or QR code. If you are within the e-invoicing mandate, generate the IRN/QR through your e-invoicing software and add it to the printed PDF.
