GST registration is the online process of getting a 15-digit GSTIN from the GST authorities, which allows a business to collect GST, claim input tax credit and file GST returns.
Last updated: October 2026. Thresholds, rules and forms are set by the GST authorities and can change, so we confirm the current position before you proceed.
Goods and Services Tax (GST) is the indirect tax on the supply of goods and services in India. Once registered, a business is given a GSTIN, can charge GST on its sales, claim input tax credit on eligible purchases and must file periodic returns.
Registration is required when your aggregate turnover goes beyond the limit for your type of supply and state. It can also be required regardless of turnover in cases such as certain interstate supplies, selling through e-commerce operators, reverse charge and non-resident taxable persons. Some businesses also register voluntarily to claim input tax credit or to sell to registered buyers and marketplaces.
For official rules, forms and the application, visit the GST portal (gst.gov.in). Companies and LLPs may also need details from the MCA portal (mca.gov.in).

A quick view of common ways a business is placed under GST.
| Option | Best for | Input tax credit | Charge GST on sales | Compliance level |
|---|---|---|---|---|
| Regular registration | Most businesses, interstate sellers and online sellers | Yes | Yes | Higher |
| Composition scheme | Small eligible businesses with limited turnover | No | No, tax paid at a fixed rate | Simpler |
| Voluntary registration | Businesses below the threshold that want credit or buyers | Yes | Yes | Same as regular |
| No registration | Businesses below the threshold with no mandatory case | No | No | None |
Most rejections and queries come from mismatched details and weak address proof.
Getting the GSTIN is only the start. Invoices and returns must follow.
Show the GST registration certificate and GSTIN at your place of business, and on your name board where required.
Raise invoices with the required details, including GSTIN, HSN or SAC code and tax amount.
File the returns that apply to your registration type by the due dates, because late filing can attract a late fee and interest.
Match your purchase records with the credit available so that you claim only what is eligible.
Update the registration if the address, name or signatory changes, and apply to cancel if the business closes.
Quick answers on GST registration in India.
GST registration is the process of getting a 15-digit Goods and Services Tax Identification Number (GSTIN) from the GST authorities. It lets a business collect GST from customers, claim input tax credit and file returns. It is done online on the GST portal.
A business must register once its aggregate turnover crosses the prescribed threshold for its type of supply and state. Registration is also required in certain cases irrespective of turnover, such as some interstate supplies, e-commerce selling, reverse charge cases and non-resident taxable persons. We confirm which rule applies to you.
The limit depends on whether you supply goods or services and on the state, and it can be lower for special category states. These limits are set by the GST authorities and can change, so we check the current figure for your case before advising.
Typical documents are PAN, Aadhaar, a photograph, proof of business address such as a rent agreement or ownership paper with NOC and utility bill, bank account proof and constitution papers for a company, LLP or partnership. Companies and LLPs also need a digital signature. We confirm the exact list for your case.
After you file, the officer reviews the application, may raise a query and then approves or rejects it. Timelines depend on document accuracy, Aadhaar authentication and the officer's review, so we cannot promise a fixed date.
There is no government fee for applying for GST registration on the GST portal. Our professional fee depends on the case and is shared in an itemised quote after a free call, along with the cost of any documents such as address proof.
Yes, if you have valid proof of the address, such as an owner NOC, a rent agreement and a utility bill. A virtual office address can work if it is backed by proper papers, but acceptance can vary by state, so we check the risk before you apply.
You receive the GST registration certificate and GSTIN. You must then issue proper tax invoices, display the registration at your place of business and file the returns that apply to you on time. Late filing can attract a late fee and interest.
Generally yes. People who supply goods through e-commerce operators usually need GST registration regardless of turnover, subject to the exemptions the GST authorities notify. Marketplaces also ask for a GSTIN while onboarding, so check the current rule for your category.
Yes. You can amend details such as address, business name or authorised signatory, and you can apply to cancel the registration if you close the business or no longer need it. Pending returns and dues must be cleared first, and we guide you through the process.
