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.

Written and reviewed by the GSTIN API team Last reviewed

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.

Types of GST registration, who takes each, and the form it is applied on.

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.

Frequently asked questions

The GST portal offers registration as a normal taxpayer (which includes the composition option), casual taxable person, non-resident taxable person, Input Service Distributor, tax deductor at source, tax collector at source (e-commerce operator), non-resident OIDAR service provider, and UN bodies, embassies and other notified persons who receive a UIN. Voluntary registration, a separate registration per business vertical and the Rule 14A simplified option are ways of taking a normal registration rather than separate types.
Both are normal registrations obtained in Form REG-01. A composition taxpayer has opted to pay tax at a flat rate on turnover under Section 10, cannot collect GST from customers, cannot claim input tax credit, issues a bill of supply instead of a tax invoice and files quarterly. A regular taxpayer charges GST on each invoice, claims input tax credit and files GSTR-1 and GSTR-3B.
A small shop selling within one state whose turnover is under the composition limit can choose between regular registration and the composition scheme. Composition is simpler and cheaper if the customers are consumers who cannot use input tax credit. Regular registration is usually better if the customers are registered businesses, because they can claim credit only on a tax invoice from a regular taxpayer.
Yes. It is granted for the period applied for, up to 90 days, and can be extended once by up to another 90 days. It needs an advance deposit of the estimated tax liability, and it is typically used for exhibitions, fairs and seasonal sales in a state where the business has no fixed place of business.
Yes. A company can be a normal taxpayer in several states, register separately as an Input Service Distributor for its head office, and hold a TDS registration if it is a notified deductor. Each registration has its own GSTIN, and all of them embed the same PAN.
