Turnover is only one part of the GST registration test: the nature and location of supplies, and the supplier’s legal status, can trigger liability from the first taxable sale.
In GST compliance, turnover is only the starting point. A business may cross the registration threshold and become liable, but the law also brings certain suppliers into the tax net immediately, regardless of sales. That distinction matters because, as the CGST Act and related notifications show, the answer to whether registration is required depends not only on revenue, but also on what is being supplied, where the supplier is based and the capacity in which the person is operating.
Under Section 22 of the CGST Act, a supplier must register in the State or Union Territory from which taxable supplies are made once aggregate turnover in a financial year crosses ₹20 lakh, or ₹10 lakh in notified special category States. For businesses engaged exclusively in supplying goods, Notification No. 10/2019-Central Tax lifts the threshold to ₹40 lakh, subject to exclusions for certain States and for goods such as ice cream, pan masala and tobacco. The statutory text also makes clear that aggregate turnover is calculated on an all-India basis across registrations under one PAN, and it includes exempt supplies, exports and inter-State supplies while excluding taxes and inward supplies taxed under reverse charge.
That broader calculation often catches traders off guard. A dealer with modest taxable sales may still breach the limit once exempt supplies are added in, while someone who supplies both goods and services generally falls back to the lower threshold. Section 22 also covers succession, amalgamation and demerger, requiring registration from the date of transfer when a business changes hands in the legal sense. As tax commentaries on Section 22 note, these rules are designed to stop businesses from treating turnover as a narrow local figure rather than a combined measure of activity.
The sharper break from the threshold test comes in Section 24, which overrides Section 22 for a list of specified persons. According to analyses of the provision, compulsory registration applies from the first taxable supply to inter-State suppliers, casual taxable persons, non-resident taxable persons, persons liable to pay tax under reverse charge, input service distributors, agents acting on behalf of other taxpayers, and e-commerce operators collecting tax or liable to pay tax under the special rules for certain services. It also extends to suppliers making sales through such operators and to foreign suppliers of online database access or retrieval services to unregistered buyers in India.
The practical effect is that a small trader can be liable long before any threshold is reached. A hardware dealer in Budgam sending a single taxable consignment to Punjab must register even if annual turnover is well below ₹40 lakh. A trader from outside the Union Territory who sets up a stall at a Srinagar exhibition is treated as a casual taxable person and must apply in advance. A government department required to deduct tax at source must register as a deductor even if it sells nothing at all.
Just as important, the law also preserves exemptions that officers and businesses alike must keep in view. Inter-State service providers below the threshold may be exempt under the Integrated Tax notification, while some sellers using e-commerce platforms also benefit from specific relief. Section 23 excludes persons dealing only in non-taxable or wholly exempt supplies, as well as agriculturists selling produce from their own cultivation. That balance is deliberate: the registration regime is meant to capture the right taxpayers, not widen the net beyond what Parliament intended.
For tax officers, then, the right question is not simply how much a person sells, but what is being sold, to whom, from where and in what legal capacity. When registration was required but not obtained, the Act allows best judgement assessment and penalty proceedings. Used carefully, the framework protects revenue without pushing compliant small traders into unnecessary registration.
