GST, Without the Maze: Registration, Returns, Rates & Notices
GST touches almost every Indian business — the registration decision, the monthly filings, the invoice format, the notice you did not expect. This hub puts every guide we have published in the order you will actually need them.
Need a GSTIN? Start with the registration service.
Guides explain the rules. If you want the number itself, our GST registration service handles the application, the Aadhaar authentication and the officer queries, end to end.
Go to GST registration →New: registration in 3 working days under Rule 14A
Since 1 November 2025, a small taxpayer whose monthly output tax liability on supplies to registered persons stays within ₹2.5 lakh can opt for Rule 14A in Form GST REG-01: Aadhaar authentication, no physical verification, and the GSTIN is granted electronically within 3 working days. One registration per PAN per state, and leaving the scheme later takes a REG-32 withdrawal — so check first, then tick the box.
