GST Registration Thresholds for Small Businesses

A business in most Indian states must register for GST once its aggregate annual turnover crosses Rs 40 lakh for goods or Rs 20 lakh for services, though several categories of business must register regardless of turnover.

Key facts at a glance

• Goods suppliers must register once turnover crosses Rs 40 lakh in most states.
• Services suppliers must register once turnover crosses Rs 20 lakh in most states.
• Special category states generally apply lower thresholds, commonly Rs 20 lakh for goods and Rs 10 lakh for services.
• Aggregate turnover is computed on an all-India, same-PAN basis, not state by state.
• The Composition Scheme threshold is Rs 1.5 crore aggregate turnover in most states.
• Inter-state suppliers, e-commerce sellers, and reverse-charge taxpayers must register regardless of turnover.
• Operating above the threshold without registering exposes a business to penalties, interest, and loss of input tax credit.

Why the threshold is not one single number

GST registration thresholds are not uniform across India. The two variables that determine which threshold applies are whether the business supplies goods or services, and whether the state it operates from is classified as a normal category state or a special category state. States classified as special category - largely in the northeast and hill regions - generally have lower thresholds, reflecting smaller local economies and a policy intent to ease compliance burden on very small businesses there.

A business supplying both goods and services needs to check which threshold applies to its combined turnover; the general rule is that if a business has any goods component, the goods threshold typically governs, but the exact treatment can depend on the mix, so this is worth confirming for mixed-supply businesses specifically.

How aggregate turnover is calculated

Aggregate turnover is not just taxable sales. It includes the value of all taxable supplies, exempt supplies, and exports made by a person with the same Permanent Account Number, computed across all of India - not just within the state where the business is registering. This matters for businesses operating in multiple states: turnover from every state combined counts toward the threshold, even if no single state's revenue alone crosses it.

Note: states can opt into the higher or lower goods threshold, so the exact figure for a given state should be confirmed on the GST portal rather than assumed uniformly.

When registration is mandatory regardless of turnover

Turnover thresholds only apply to businesses that fall into the general category. Several categories of supplier must register for GST irrespective of how small their turnover is. These include businesses making inter-state taxable supplies, casual taxable persons, non-resident taxable persons, e-commerce operators and sellers supplying through e-commerce platforms in many cases, businesses required to pay tax under the reverse charge mechanism, and input service distributors. A small business that assumes it is safe because its revenue is below Rs 20 lakh can still be legally required to register if it falls into one of these categories.

The Composition Scheme as an alternative, not an exemption

Businesses under the Rs 1.5 crore aggregate turnover limit can opt for the Composition Scheme instead of regular GST registration, paying tax at a lower fixed rate on turnover with substantially simplified return filing. The trade-off is real restrictions: composition taxpayers generally cannot make inter-state outward supplies, cannot collect GST from customers, and cannot claim input tax credit. This makes the scheme a good fit for small, purely local businesses, but a poor fit for anyone planning to sell across state lines or serve GST-registered business customers who need input credit.

The cost of missing the threshold

Once a business crosses the applicable threshold, registration becomes mandatory, typically within a defined window from the date the threshold is crossed. Continuing to operate unregistered beyond that point exposes the business to interest on unpaid tax, penalties, and the practical problem that any GST collected without registration cannot be legitimately passed through as input credit to customers, which can damage business relationships as much as it triggers regulatory risk.
