GST Registration in India — GSTIN Registration, Returns & Compliance

The threshold depends on your state and whether you supply goods or services — it is lower for special-category states and for service providers than for goods suppliers in most other states. Regardless of turnover, registration is mandatory immediately if you supply goods or services across state lines or sell through an e-commerce marketplace. We confirm the exact current threshold that applies to your specific business before advising you.

Yes. Voluntary registration is common among startups and B2B service providers who want to claim input tax credit on their expenses or need a GSTIN to invoice larger corporate clients, even before turnover requires it. Once voluntarily registered, the same monthly or quarterly filing obligations apply as for any other regular taxpayer.

GSTR-1 is a detailed, invoice-level return reporting your outward supplies for the period. GSTR-3B is a summary return declaring total tax liability and input tax credit claimed, and is the return against which you actually pay tax. Both are filed monthly or quarterly depending on your turnover and scheme, and mismatches between the two are a common source of notices from the department.

No. GST registration is mandatory for any seller on an e-commerce marketplace in India, regardless of turnover, because marketplaces are required to collect Tax Collected at Source against a valid GSTIN. This is one of the most common reasons founders register for GST before they've crossed the general turnover threshold.

The Composition Scheme lets small businesses with turnover under a defined ceiling pay GST at a fixed, lower rate on turnover instead of standard slab rates, in exchange for simpler quarterly filing and no input tax credit. It's generally only available for intra-state supply of goods and select services — inter-state sellers and e-commerce sellers are not eligible. We check your eligibility against current rules before recommending it.

Straightforward applications are typically approved within 3–7 working days of ARN generation. If the department raises a clarification query, or orders physical verification of your registered office, the timeline extends until that query is resolved — which is why complete, consistent documentation upfront matters most.

Late filing attracts a late fee per day of delay, subject to a cap that differs by return type, plus interest on any unpaid tax liability, and consistently missed returns can lead to the GSTIN being flagged or suspended. We track every client's filing calendar so due dates are never missed.

Yes. GST registration can be surrendered through a cancellation application on the portal, along with a final return, once you stop taxable supply or your turnover permanently falls below the threshold and you no longer wish to remain voluntarily registered. Outstanding returns and tax dues must be cleared before cancellation is approved.
