About this service

Governed by the CGST Act, 2017, GST registration enables businesses to legally collect indirect tax, claim seamless Input Tax Credit (ITC) on inputs and capital goods, and transact across state boundaries without supply disruptions. Filings are submitted digitally on the GST Common Portal.

Common mistakes to avoid

Avoidable filing errors that cause delays or rejection. Each can be resolved before submission.

  1. 1
    Address mismatch between electricity bill and rent agreement
    Why: GST officers reject or issue Show Cause Notice (REG-03) if the premise address differs even by a room or floor number.
    Fix: We cross-verify every line of the address across the utility bill, lease deed, and owner NOC before portal upload.
  2. 2
    Submitting savings account proof instead of business bank details
    Why: Rule 10A of CGST Rules mandates bank details must strictly match the commercial entity name within statutory limits.
    Fix: We guide you through current account activation and file the bank amendment within the prescribed period.
  3. 3
    Demographic data mismatch between PAN and Aadhaar
    Why: Aadhaar authentication fails if spelling or DOB differs from income-tax records, triggering physical site verification.
    Fix: We pre-validate PAN-Aadhaar linkage and resolve discrepancies before initiating registration.
