Whether an online seller in India needs GST registration depends on what they sell, where they sell it, how they sell it, and whether a current exception applies. The CGST Act includes compulsory-registration rules for certain sellers using e-commerce operators that collect tax at source, but eligible small goods sellers may be covered by a later exception. The available official sources do not establish that exception’s full current conditions or limits, so neither “every marketplace seller must register” nor “small turnover means no registration” is a safe general rule.
If registration is required—or you choose to register voluntarily—the official application is Form GST REG-01 on the GST Portal, under Services > Registration > New Registration. This guide covers the decision points and application steps for India; confirm the current rules for the relevant State or Union Territory and your specific transactions.
When does an online seller need GST registration?
Section 24 of the CBIC-hosted Central Goods and Services Tax Act lists categories that must register notwithstanding the ordinary threshold under section 22. They include specified suppliers making supplies through e-commerce operators required to collect tax under section 52. The same Act provides a 30-day period to apply after liability arises.

The CBIC sectoral FAQ describes the general marketplace-supplier rule and an exception for certain service suppliers, while the GST Portal/GST Network’s April 2023–March 2024 functionality compilation notes that an unregistered person supplying through an e-commerce operator can generate a portal user ID. Neither source establishes the complete current eligibility terms for the later route that may allow certain goods sellers to sell through an operator without ordinary registration. A portal user ID is not, by itself, proof that a seller qualifies for that route.

For a definitive answer, check the current notification and apply it to the seller’s actual facts. In particular, distinguish supplies made through a marketplace from direct sales through the seller’s own site; the relevant compulsory-registration provision refers to certain e-commerce operators, not online selling in the abstract.
Check these facts before deciding
| What to establish | Why it matters |
|---|---|
| Whether you sell goods, services, or both | The statutory provisions and possible notified exceptions may treat types of supply differently. See the CGST Act and CBIC sectoral FAQ. |
| Whether sales are direct or through an e-commerce operator, and whether that operator is required to collect tax under section 52 for the relevant transactions | The compulsory-registration category concerns specified supplies through covered operators; it should not automatically be applied to every online sale. See the CGST Act. |
| Your State or Union Territory, place of business, and whether supplies are intra-state, inter-state, or both | Registration is filed for a selected State/UT, and the applicable rule or exception may depend on the seller’s location and supplies. The portal’s registration guide requests the State/UT and business-premises details. |
| Aggregate turnover, any current notification-specific threshold or restrictions, and other registrations or activities | Turnover alone may not settle whether a marketplace seller must register; another activity can independently trigger a registration obligation. The CGST Act and GST Portal/GST Network functionality compilation do not state the complete current goods-seller exception conditions. |
If you are uncertain whether the current exception covers your situation, verify the operative notification before relying on it. The cited Act and CBIC FAQ describe the general framework, and the portal compilation reports a related functionality; these materials do not provide the full current conditions and limits for the goods-seller route.

How to apply for GST registration online
The GST Portal’s Normal Taxpayer registration guide describes the REG-01 process in two parts.
Free tools Windows power users keep installed
One-click scans. No signup required.
- Open the new-registration form. On the GST Portal, go to Services > Registration > New Registration.
- Complete Part A. Select Taxpayer, choose the relevant State/UT and district, and enter the PAN-linked legal name, PAN, and primary authorized signatory’s email address and Indian mobile number.
- Verify your contact details. Enter the separate email and mobile OTPs. The portal generates a Temporary Reference Number (TRN) for continuing the application.
- Return with the TRN and complete Part B. Fill in the business details and the requested information for promoters or partners, authorized signatory, authorized representative, principal and additional places of business, goods and services, state-specific information, Aadhaar authentication, and verification.
- Submit and complete the prompted authentication. Depending on the checks applied to the application, the portal may require Aadhaar OTP authentication or biometric and document authentication. Follow the current portal instructions and retain the acknowledgement and Application Reference Number (ARN).
Prepare premises evidence and plan for verification
Have evidence for the business premises ready before completing the application. The portal guide gives a property-tax receipt, municipal khata copy, or electricity bill as examples for owned premises. For rented premises, it lists a valid rent or lease agreement together with supporting evidence of the owner’s premises. The exact documents requested depend on the applicant’s circumstances and the portal’s current prompts.
The registration guide says that a normal taxpayer who applies within 30 days after liability arises has registration effective from the date the liability arose. If the application is delayed, the liability date remains the same, but registration takes effect from the date it is granted. Check the portal’s current process and retain the application acknowledgement.

Registration brings return-filing and transaction-reporting responsibilities. The GST Portal’s GSTR-1 guidance says registered taxpayers with an active GSTIN for the relevant period file the return. Supplies through e-commerce operators may need to be reported differently depending on whether the operator collects tax under section 52 or pays tax under section 9(5). The applicable table and treatment depend on the transaction and current form instructions; see also the portal’s GSTR-1 outward-supplies guidance.
