Types of GST Registration in India, Explained
Normal, composition, casual, non-resident, ISD, TDS, TCS, OIDAR and UIN: every GST registration type, who needs it, and the form each one is applied on.
There is one GST law but several types of GST registration, each built for a different kind of taxpayer: the ordinary business, the small trader on a flat rate, the exhibitor in another state for a week, the head office distributing credit, the government department deducting tax, the foreign streaming service. They are applied for on different forms, carry different obligations, and show up differently when someone looks up the GSTIN. This guide walks through each one.
All types at a glance
| Type | For | Form |
|---|---|---|
| Normal — regular | Businesses above the threshold, compulsory categories, voluntary registrants | REG-01 |
| Normal — composition | Small taxpayers who opt to pay a flat rate on turnover | REG-01 (or CMP-02 to switch) |
| Casual taxable person | Occasional supplies in a state with no fixed place of business | REG-01 |
| Non-resident taxable person | Foreign persons making occasional taxable supplies in India | REG-09 |
| Input Service Distributor | Offices distributing credit on common input services to branches | REG-01 |
| Tax deductor (TDS) | Government departments and other notified deductors under Section 51 | REG-07 |
| Tax collector (TCS) | E-commerce operators collecting tax under Section 52 | REG-07 |
| Non-resident OIDAR supplier | Foreign providers of online services to Indian non-business recipients | REG-10 |
| UIN holder | UN bodies, embassies, consulates and other notified persons | REG-13 |
Normal taxpayer
This is the registration nearly every business holds. It is compulsory once aggregate turnover crosses the threshold, and compulsory from the first rupee for the categories listed in Section 24: inter-state suppliers of goods, persons liable under reverse charge, e-commerce sellers of goods and several others. The turnover limit guide covers both routes.
A regular taxpayer issues tax invoices, charges GST, claims input tax credit, files GSTR-1 for sales and GSTR-3B for the summary and payment, and files the annual return. The list of GST returns shows which return applies to which type.
Composition taxpayer
Composition is not a separate registration but an option within a normal one, under Section 10. The taxpayer pays tax at a low flat rate on turnover, cannot collect GST from customers, cannot claim input tax credit, and issues a bill of supply rather than a tax invoice. Returns are lighter: a quarterly CMP-08 statement and an annual GSTR-4. Eligibility has a turnover limit and excludes inter-state suppliers of goods, e-commerce sellers of goods and certain manufacturers. The full conditions are in the composition scheme guide.
Casual and non-resident taxable persons
A casual taxable person is an Indian business that makes occasional taxable supplies in a state where it has no fixed place of business, such as at a trade fair. The registration is valid for the period applied for, up to 90 days, extendable once, and needs an advance deposit of estimated tax. It is covered in detail in the casual taxable person guide.
A non-resident taxable person is the foreign equivalent: someone with no business establishment in India who occasionally makes taxable supplies here. The application is in Form REG-09, with a passport or foreign tax identifier in place of a PAN, and it too needs an advance deposit.
Input Service Distributor
A head office that receives invoices for services used by branches in several states registers as an ISD to distribute that credit to the branch GSTINs. It makes no supplies and pays no output tax of its own. The ISD registration sits alongside the office's normal registration and has its own GSTIN. See Input Service Distributor under GST.
TDS deductor and TCS collector
Under Section 51, government departments, local authorities and other notified bodies deduct tax from payments to suppliers above a limit, and must register as deductors. Under Section 52, e-commerce operators collect tax on the net value of supplies made through them and must register as collectors, whatever their turnover. Both apply in Form REG-07. The mechanics are in GST TDS and TCS explained.
OIDAR suppliers and UIN holders
A foreign company that supplies online information and database access or retrieval services — streaming, cloud software, online advertising — to consumers and other non-business recipients in India registers in Form REG-10 under a simplified scheme and pays IGST itself. Where the Indian customer is a registered business, the customer pays under reverse charge instead. See OIDAR and GST for foreign SaaS.
UN bodies, embassies and consulates do not make taxable supplies but may claim refunds of tax they pay on purchases. They receive a Unique Identification Number in place of a GSTIN. The UIN guide explains how it differs.
Voluntary, vertical and Rule 14A registrations
Three things are often described as "types" but are really ways of taking a normal registration:
- Voluntary registration — a business below the threshold registers anyway, usually so that its business customers can claim credit. Once registered, it has every obligation of a regular taxpayer.
- Separate registration for a business vertical — a PAN may take more than one registration in the same state for distinct places or lines of business. See multiple registrations on one PAN.
- The Rule 14A simplified option — small applicants whose B2B output tax stays under ₹2.5 lakh a month can opt for registration within 3 working days. See Rule 14A simplified registration.
How the type shows on the public record
A GSTIN lookup returns a taxpayer type field — Regular, Composition, Input Service Distributor, Tax Deductor, Tax Collector, Casual Taxable Person, Non-Resident and so on. It is worth reading before you pay a supplier. A composition supplier who charges GST on an invoice has charged tax it was not allowed to collect, and the credit is not available to you. Our guide to the taxpayer type field lists each value and what it implies.
