This calculator gives an estimate for general information. It is not tax or legal advice. Check the applicable rate and rules for your case on the official sources below or with a qualified professional.

How to use the Invoice Generator

  1. Fill in your business details and the customer's. A valid GSTIN fills in the state automatically.
  2. Choose the place of supply — it decides CGST + SGST or IGST.
  3. Add items with HSN/SAC, quantity, rate, discount and GST rate.
  4. Click Download PDF / Print and choose “Save as PDF”.

What a GST tax invoice must show

  • Supplier's name, address and GSTIN.
  • A consecutive invoice number of up to 16 characters, unique for the financial year, and the date of issue.
  • Recipient's name, address and GSTIN (if registered), and the place of supply with state name.
  • HSN code for goods or SAC for services, description, quantity and unit.
  • Taxable value after discounts, and the rate and amount of CGST, SGST/UTGST or IGST.
  • Whether tax is payable under reverse charge, and a signature or digital signature.

The number of HSN digits required depends on your turnover and whether the sale is B2B or B2C. Check the current notification for your case.

E-invoicing

Important

Businesses above the notified turnover threshold must generate e-invoices (with an IRN and QR code) through the government's Invoice Registration Portal. This tool does not create IRNs; use it for businesses below the threshold or for drafts.

Worked example

Two items, supplier in Delhi, customer in Delhi

  1. Laptop stand: 2 × ₹1,000 @ 18% → ₹2,000 + ₹360
  2. Tea: 3 × ₹499.50 @ 5% → ₹1,498.50 + ₹74.93
  3. Same state → CGST ₹217.47 + SGST ₹217.46

Invoice total ₹3,933.43, rounded to ₹3,933
