These details are printed on your invoices and decide how GST is charged. You'll need your PAN and, if you're registered, your GST registration certificate.
Are you registered for GST?
- Yes: enter your GSTIN. We'll add the correct GST to every invoice automatically.
- No: your invoices won't show GST at all. If you register later, come back here and switch it on.
GSTIN
Your 15-character GST number, for example 27AAACM1234K1ZN. It's on your registration certificate (Form REG-06).
When you type a valid GSTIN, we fill in your PAN and state from it, because the GSTIN already contains them:
| Characters | Meaning |
|---|---|
| 1–2 | Your state code (27 = Maharashtra) |
| 3–12 | Your PAN |
| 13–15 | Registration number and a check character |
If we say the GSTIN "doesn't match", it's almost always a typing mistake. Copy it again from the certificate.
Regular or Composition scheme?
Most businesses are on the Regular scheme. Choose Composition only if you opted for it; you then issue a Bill of Supply instead of a tax invoice, and don't charge GST.
State
The state of your registered office decides which GST applies:
- Client in the same state: CGST + SGST (half each).
- Client in a different state: IGST.
If you have offices in other states with their own GSTINs, you'll be able to add them under Offices in a later release.
Annual turnover
Your total turnover across India last financial year. It decides how many digits of HSN/SAC code your invoices need and whether e-invoicing applies to you. You can leave it blank for now.
Udyam registration (optional)
If you're a registered micro, small or medium enterprise, add your Udyam number, like UDYAM-MH-01-0012345. We'll print it on your invoices and, later, flag buyers who pay you later than the 45 days the MSMED Act allows.
