How to Make a GST Invoice PDF in India (2026)

The GST calculator guide answers “what is the tax on this line?” This page is the next click: put those numbers on a bill and download a PDF. FlashKit’s GST invoice generator formats a GST-style tax invoice in the current tab. It does not talk to GSTN, issue an IRN, or print a government-signed QR.

Updated for GST 2.0 (rates effective 22 Sep 2025). Verify HSN/SAC and place of supply with a CA / official notification.

What you will type

  1. Seller and buyer: legal name, address, optional 15-character GSTIN (state + PAN + entity + Z + checksum). B2C invoices may leave the buyer GSTIN blank. A bad GSTIN format blocks export.
  2. Invoice number, date, optional due date, and place of supply. The tool splits tax automatically: same seller state and place of supply → CGST + SGST; different states → IGST. Union-territory supplies use UTGST in the statute — ask the person who files if your POS is a UT.
  3. Lines: description, HSN (goods) or SAC (services), quantity, rate, discount, and a GST 2.0 slab (0 / 5 / 18 / 40%, plus special 3% gold / 0.25% rough diamonds, custom, or labeled pre-22-Sep-2025 12% / 28% for old invoices).
  4. Review taxable value, tax heads, nearest-rupee round-off, and amount in Indian words (lakh/crore).
  5. Download the client-side PDF, print, or save a draft in this browser’s localStorage. Nothing is uploaded to FlashKit.

Do the arithmetic first if you are unsure

If a line is tax-inclusive and you are guessing the taxable value, run it through the GST calculator first. Worked CGST+SGST vs IGST numbers: invoice examples. Basics: CGST, SGST, IGST.

After you download

  • If the PDF is too large for email (logo-heavy), try the PDF compressor — JPEG recompress, local only.
  • If you take UPI on a printed copy, encode a URL or UPI string you control with the QR generator. Do not laminate an expiring payment-link QR.
  • Notified taxpayers who must e-invoice still need the Invoice Registration Portal. This PDF is a draft or a simple bill, not an IRN.

Disclaimer (not financial advice)

FlashKit calculators run reducing-balance EMI and compound-SIP arithmetic in your browser. They are planning aids, not a bank sanction letter, a GSTN filing, SEBI-registered investment advice, or a substitute for a chartered accountant. Actual EMI depends on processing fees, insurance, prepayment clauses, and the lender’s day-count. Mutual-fund returns are not guaranteed. Confirm numbers with your lender or advisor before you sign.
