# Which Business Situations Need a Compulsory GST Registration Review? ## Review the activity before the turnover figure Section 24 of the CGST Act identifies situations where registration can be required independently of the ordinary turnover threshold. These include particular inter-State supplies, casual and non-resident taxable persons, specified reverse charge obligations, certain agency arrangements, Input Service Distributors and specified e-commerce roles. The correct review is based on what the business does and in what capacity. However, a section heading is not the whole answer. Notifications can exempt defined classes subject to conditions, and later amendments may change a category's operation. Read the relevant provision with the applicable exemption and effective date. Statements such as “every online seller must register” or “every inter-State service invoice requires registration” can produce the wrong outcome. ## Map the facts that can change liability Create a transaction map showing who supplies, who receives, where each is located, where goods are dispatched, and who issues the invoice. Add whether the business owns the goods, acts for another supplier, runs the platform or merely sells through it. The same customer order can involve several legally distinct businesses. Include unusual activities such as a temporary exhibition, imported service, auction arrangement or central purchasing office. These can be missed in an annual sales summary. A small operation should review the facts before entering a new model, rather than waiting for year-end revenue to reach a familiar threshold. ## Inter-State supplies and temporary selling An inter-State supply needs attention because it appears in the compulsory registration framework, but relief exists for specified classes, including certain service suppliers. Establish the nature of supply and the applicable notification rather than treating the customer's postal address as a complete place-of-supply analysis. A temporary fair or trade event can raise a casual taxable person question when supplies are made in a State where the seller has no fixed place of business. Taking orders at a display counter and delivering later from an existing establishment may present different facts from selling stock at the event. Keep the event agreement and proposed invoice flow available for review. Illustratively, a Jaipur craft business expects only ₹1.8 lakh of sales at a five-day Bengaluru exhibition. That small event value does not settle registration. The owner should assess whether goods are actually supplied at the stall, whether the casual taxable person definition applies and whether any specific exemption covers the activity. Review this before moving stock or collecting customer payments. ## Reverse charge and representative roles A business required to pay GST under reverse charge must consider the corresponding registration rule and any available relief. Do not infer an obligation merely from receiving a bill without GST. First establish the notified supply, supplier and recipient categories, and the exact reverse charge condition. An agency review should examine the contract and invoicing practice. A person introducing buyers for a fee is not automatically identical to an agent making taxable supplies on another person's behalf. Record who transfers goods, who raises invoices and whose name appears on the customer-facing documents. Legal labels such as “distributor” can conceal different operating models. Input Service Distributor, TDS and TCS registrations also depend on specified legal roles. An ordinary trader does not become a GST deductor simply because it deducts income tax TDS, and a head office should not treat every internal cost allocation as an ISD transaction without examining the current framework. ## E-commerce requires two separate reviews First assess the operator's role and whether it is required to collect GST under section 52 or pay tax on a notified supply under section 9(5). Then assess the seller's obligation. Platform ownership, payment collection and the nature of the underlying supply matter; a website selling only its owner's goods is not the same factual arrangement as a marketplace for independent suppliers. Notification 34/2023-Central Tax, effective 1 October 2023, provides a conditional registration exemption for certain small suppliers of goods through e-commerce operators. Among its conditions are turnover limits, no inter-State goods supplies, supplies through the operator in only one State or Union territory, PAN validation and portal enrolment before such supplies. That exemption is not a blanket permission for every small online seller. A seller planning nationwide goods deliveries should examine the inter-State restriction. Service suppliers have a different notification framework, and supplies covered by section 9(5) need separate treatment. Keep platform contracts and dispatch settings with the registration assessment. Ask for a written description of the first proposed transaction in any unfamiliar model. For an agency arrangement, obtain a sample customer invoice; for an event, obtain the stall agreement; for a platform, obtain settlement and seller terms. These practical records often expose a missing fact faster than a lengthy business description built around labels whose meaning nobody has checked. ## Turn the review into a usable decision Prepare a short issue register with one row per activity, the potential registration provision, any exemption considered and the evidence still needed. Note the intended start date. This helps distinguish a real liability from a scenario that only requires monitoring while preventing unresolved questions from disappearing into routine bookkeeping. For each conclusion, retain the notification or official instruction relied on and identify the facts that must remain true. If an exemption depends on intra-State selling, review it when delivery coverage changes. If it depends on turnover, track the combined PAN-based figure during the year. Compulsory registration is best handled as an early business-model check. A precise transaction map and a documented exception review usually provide a stronger answer than comparing sales with a single headline threshold. ## Sources and references - [CBIC: Central Goods and Services Tax Act, consolidated through August 2021](https://cbic-gst.gov.in/pdf/CGST-Act-Updated-31082021.pdf) - [Notification 34/2023-Central Tax: conditional exemption for goods through ECOs](https://gstcouncil.gov.in/sites/default/files/2024-05/gst-ct-34-2023.pdf) - [GSTN: Applying for normal taxpayer registration](https://tutorial.gst.gov.in/userguide/registration/Apply_for_Registration_Normal_Taxpayer.htm)
