GST Registration 2026: Eligibility, Documents, Fees and the Complete Application Process
Executive Summary
GST registration gives your business a 15-digit GSTIN. With it you can collect GST from customers, claim input tax credit on purchases, sell across state lines and list on marketplaces like Amazon and Flipkart. Without it, a business that is required to register risks penalties, cannot issue valid tax invoices and is shut out of most B2B and government buyers.
Registration itself is free on the government portal. What decides how fast you get your GSTIN is the quality of the application: names that match PAN and Aadhaar, a valid proof of business premises, the right HSN/SAC codes and timely replies to any officer query.
Since 1 November 2025, two faster routes exist. Rule 9A lets the system approve low-risk applications within three working days, and the optional Rule 14A simplified scheme grants registration within three working days to small B2B suppliers who complete Aadhaar authentication. This guide covers who must register, what you need, both routes, and the mistakes that most often lead to rejection.
Key Facts About GST Registration in 2026

Our GST practitioners prepare and file your application on the official portal and handle any officer query.
Part 1: Who Must Register for GST
Registration Based on Turnover (Section 22)
You must register once your aggregate turnover in a financial year crosses the threshold for your state. Aggregate turnover is calculated on your PAN across India and includes taxable supplies, exempt supplies, exports and inter-state supplies between your own branches. It excludes GST itself and inward supplies taxed under reverse charge.
| State Category | Supplying Only Goods | Supplying Services (or Goods + Services) |
|---|---|---|
| Most States and UTs | ₹40 lakh | ₹20 lakh |
| Telangana and Puducherry | ₹20 lakh | ₹20 lakh |
| Manipur, Mizoram, Nagaland and Tripura | ₹20 lakh | ₹10 lakh |
Note: The higher ₹40 lakh limit applies only when all your supplies are goods, and it does not apply to certain goods such as ice cream, pan masala and tobacco products. States can change their choice by notification, so confirm the current position for your state before deciding not to register.
Compulsory Registration Regardless of Turnover (Section 24)
These businesses must register even if their turnover is below the limit:
- Inter-state suppliers of goods — selling goods from one state to a buyer in another
- E-commerce sellers of goods — selling through Amazon, Flipkart, Meesho and similar operators (see the intra-state relaxation in Part 5)
- Casual taxable persons — making supplies from a temporary place, such as a trade fair in another state
- Persons liable under reverse charge
- Non-resident taxable persons
- Input Service Distributors, and persons required to deduct TDS or collect TCS under GST
- Agents supplying on behalf of other taxable persons
- E-commerce operators and suppliers of online information and database access services (OIDAR) from outside India
Voluntary Registration
Businesses below the threshold can still register. Most do it to claim input tax credit, to qualify for B2B clients and government tenders that only buy from GST-registered suppliers, or to list on marketplaces. Voluntary registration carries the same return-filing duties as compulsory registration, so plan for regular GST return filing from the first month.
Part 2: Documents Required for GST Registration
Proprietorship / Individual
- PAN card of the proprietor
- Aadhaar card of the proprietor, with mobile number linked for OTP
- Passport-size photograph
- Proof of business premises (see below)
Partnership Firm / LLP
- PAN of the firm or LLP
- Partnership deed, or LLP agreement and certificate of incorporation
- PAN, Aadhaar and photograph of each partner or designated partner
- Authorisation letter naming the authorised signatory
- Proof of business premises
- DSC of the authorised signatory (mandatory for LLPs)
Private Limited / OPC / Public Company
- PAN of the company
- Certificate of incorporation, MOA and AOA
- PAN, Aadhaar and photograph of each director
- Board resolution appointing the authorised signatory
- Proof of registered office or business premises
- Class 3 DSC of the authorised signatory (mandatory for companies)
Proof of Principal Place of Business

- Premises owned by a relative or shared: consent letter from the owner with the owner's ID proof and an electricity bill or property tax receipt
- SEZ units: the relevant SEZ approval documents
Bank Account Details
Bank details are not needed to submit the application. Under Rule 10A, you add them after registration — within 30 days of the grant or before filing your first GSTR-1/IFF, whichever is earlier. Keep a cancelled cheque or a bank statement showing the account holder's name, account number and IFSC ready.
Part 3: GST Registration Fees, Charges and Timelines
What GST Registration Costs
The government charges no fee for GST registration. When you use a consultant, you pay only their professional fee for checking documents, preparing the application, choosing the right HSN/SAC codes, responding to clarification notices and guiding you after registration. If any website claims a "government fee" for GST registration, treat that as a warning sign.
How Long It Takes
| Route | Who It Is For | Approval Timeline |
|---|---|---|
| Rule 14A — Simplified Registration (optional) | Applicants whose monthly output tax on supplies to registered persons will not exceed ₹2.5 lakh; Aadhaar authentication mandatory | Within 3 working days of ARN |
| Rule 9A — System-based approval | Normal applications identified as low-risk by the system's data analysis | Within 3 working days of ARN |
| Normal route with Aadhaar authentication | Applications reviewed by the proper officer | Within 7 working days |
| Without Aadhaar authentication, or physical verification needed | Applications flagged for site verification | Up to 30 days |
If the officer asks for clarification in Form GST REG-03, the clock restarts from your reply in Form GST REG-04, which must be filed within seven working days.

Part 4: Step-by-Step Process to Apply for GST Registration Online
Check Whether You Need Registration
Compare your expected aggregate turnover with your state's limit in Part 1, and check whether any compulsory category applies — especially inter-state sales of goods or selling on marketplaces. If none applies, decide whether voluntary registration makes commercial sense for you.
Prepare Your Documents
Collect the documents listed in Part 2. Check that the name on PAN, Aadhaar and the address proof match exactly, and that the electricity bill or tax receipt is recent and fully legible.
Fill Part A of Form GST REG-01 and Get a TRN
Visit: https://www.gst.gov.in → Services → Registration → New Registration
- Verify the address is exactly "gst.gov.in" before entering any details
- The browser should show the lock icon and "https://"
- Never share portal OTPs with anyone you have not engaged to file for you
- Select "Taxpayer", your State/UT and district
- Enter the legal name as per PAN, the PAN, email and mobile number
- Verify the OTPs sent to the mobile and email
- Note the Temporary Reference Number (TRN). You have 15 days to complete Part B
Complete Part B of the Application
- Log in with the TRN and fill business details: trade name, constitution, date of commencement and reason for registration
- Add promoters or partners and the authorised signatory with their photographs
- Enter the principal place of business and any additional places, and upload address proof
- Add the top goods (HSN codes) or services (SAC codes) you supply
- Fill state-specific information where the portal asks for it
Opt for Rule 14A if You Qualify
The REG-01 form asks whether you want registration under Rule 14A. Choose "Yes" only if your monthly output tax on supplies to registered persons — CGST, SGST/UTGST, IGST and cess together — will not exceed ₹2.5 lakh.
Choose Aadhaar Authentication and Submit
- Opt for Aadhaar authentication for the promoters and authorised signatory
- Submit with EVC (OTP) or DSC — DSC is mandatory for companies and LLPs
- Complete the Aadhaar OTP authentication sent to each person's Aadhaar-linked mobile
- If the system flags the application, book an appointment at a GST Suvidha Kendra for biometric Aadhaar authentication and photograph capture, and take your original documents
- The portal generates an Application Reference Number (ARN) to track the application
Respond to Any Clarification Notice
If the officer needs more information, you will receive Form GST REG-03 by email and on the portal. File your reply in Form GST REG-04 with the requested documents within seven working days. A clear, complete reply the first time is the fastest way to approval.
Download the Certificate and Complete Post-Registration Steps
- Download the certificate in Form GST REG-06 from Services → User Services → View/Download Certificates
- Add bank account details within 30 days, or before filing your first GSTR-1/IFF, whichever is earlier
- Display the registration certificate at your principal place of business and the GSTIN on the name board at the entrance, as required by Rule 18
- Start issuing tax invoices showing your GSTIN
- Note your return due dates and file from the first period, even if it is a Nil return
Skip the portal back-and-forth
Share your details once. We prepare, file and track your GST application until the certificate is issued.
Part 5: GST Registration for Your Type of Business
GST Registration for Amazon, Flipkart and Meesho Sellers
Sellers of goods through e-commerce operators generally need GST registration from the first sale, regardless of turnover. Since 1 October 2023, small sellers below the threshold can sell goods within their own state through e-commerce using a PAN-based enrolment number instead of full registration. Selling to buyers in other states still requires a GSTIN, so most sellers who want an all-India audience register. If you store stock in marketplace fulfilment centres in other states, each of those states needs its own registration or an additional place of business, depending on the arrangement.
GST Registration for Freelancers and Service Providers
Freelancers, consultants, designers, developers and agencies must register once aggregate turnover crosses ₹20 lakh (₹10 lakh in Manipur, Mizoram, Nagaland and Tripura). Income from foreign clients counts towards this limit. Inter-state supply of services does not by itself force registration below the threshold. Registered service exporters can file a Letter of Undertaking (LUT) to export without paying IGST.
GST Registration for Proprietorships and Home Businesses
A proprietor registers with their personal PAN. A home address can be the principal place of business — use your electricity bill or property tax receipt, and a consent letter if the house is in a family member's name.
GST Registration for Private Limited Companies, OPCs and LLPs
Companies and LLPs register using the entity's PAN and must sign the application with a DSC. Most startups register immediately after incorporation, because investors, enterprise clients and marketplaces expect a GSTIN on invoices. If you are still deciding your structure, read our comparison of company types before you incorporate.
Composition Scheme Registration
Traders, manufacturers and restaurants with aggregate turnover up to ₹1.5 crore (₹75 lakh in some North-Eastern and hill states) can opt for the Composition Scheme and pay tax at a fixed rate on turnover, with quarterly CMP-08 and an annual GSTR-4 instead of monthly returns. Service providers can opt for a separate composition option up to ₹50 lakh. Composition dealers cannot claim input tax credit, cannot make inter-state supplies of goods and cannot sell goods through e-commerce operators.
Part 6: Rules You Cannot Work Around
Limits Built Into the Law
- Your GSTIN embeds your PAN and state code — you cannot use one state's GSTIN for a place of business in another state
- Additional premises in the same state are added as additional places of business, not as a new GSTIN
- A change in constitution that changes the PAN (for example, a proprietorship becoming a company) needs a fresh registration
- Check the legal name and PAN carefully before submitting
- The limit is self-declared, but under-declaring to qualify can lead to action, including cancellation
- If your B2B tax liability will grow beyond the limit, use the normal route from the start
- A registered GSTIN must keep filing returns until it is formally cancelled
- After cancellation, a final return in GSTR-10 is still due
Part 7: Real-World GST Registration Scenarios
Scenario 1: New Amazon Seller Shipping Across India
Example Business: Kavita makes handmade candles in Jaipur and wants to sell on Amazon to buyers in every state.
What Kavita Needs:
- A GSTIN in Rajasthan before she can sell to buyers in other states, even though her turnover is far below ₹40 lakh
- Her home workshop as the principal place of business, with her electricity bill as proof
- An additional place of business, or registration in another state, if she later uses a fulfilment centre outside Rajasthan
Outcome: Registered in a few working days under Rule 14A, since her B2B tax liability is minimal, and listed on the marketplace the same week.
Scenario 2: Freelance Developer With Foreign Clients
Example Business: Arif, a developer in Pune, billed ₹18 lakh last year, mostly to US clients, and expects ₹26 lakh this year.
What Arif Should Do:
- Register as soon as his aggregate turnover is about to cross ₹20 lakh, because export income counts towards the limit
- File a Letter of Undertaking (LUT) so he can invoice foreign clients without paying IGST
- Keep foreign inward remittance records for each export invoice
Outcome: Compliant from the right date, with no GST cost on his export invoices.
Scenario 3: Startup Registered as a Private Limited Company
Example Business: A two-founder SaaS startup in Bengaluru, incorporated last month, has its first enterprise client asking for a GST invoice.
What They Need:
- The company's PAN, certificate of incorporation, MOA and AOA
- A board resolution naming one founder as authorised signatory, with that founder's Class 3 DSC
- A rent agreement and the landlord's electricity bill for the office
Outcome: A GSTIN that lets the client claim input tax credit on the startup's invoices — often a condition of the contract.
Scenario 4: Trader Who Crossed the Limit Without Noticing
Example Business: Manoj runs a hardware shop in Lucknow. His sales grew from ₹32 lakh to ₹46 lakh this year, and he crossed ₹40 lakh in January.
The Problem: The law requires an application within 30 days of becoming liable. Manoj only realised in May.
What Manoj Should Do:
- Apply immediately, giving the correct date on which he became liable
- Take professional advice on tax for the period between becoming liable and registration
- Track monthly turnover against the limit from now on
Lesson: Late registration does not erase the liability for the gap period. Monitoring turnover monthly avoids the problem entirely.
Part 8: Common Mistakes That Cause GST Registration Rejection
Mistake 1: Name Mismatch Between PAN, Aadhaar and the Application
The Problem:
Sunil entered "Sunil Kumar Traders" as his legal name. His PAN shows "SUNIL KUMAR". The application failed PAN validation, and a corrected one needed fresh OTPs.
- The legal name is always the name on PAN — your shop name goes in "trade name"
- Check that Aadhaar spelling matches PAN before applying
Mistake 2: Weak or Mismatched Address Proof
The Problem:
Ritu uploaded an unsigned rent agreement and her own Aadhaar as address proof. The officer issued REG-03 asking for the landlord's ownership proof, adding a week.
- For rented premises, upload the signed agreement and the owner's electricity bill or tax receipt
- Make sure the address typed in the form matches the proof word for word
- Use a recent bill, not one that is several months old
Mistake 3: Skipping Aadhaar Authentication
The Problem:
Deepak chose not to opt for Aadhaar authentication to save time. His application went into the physical verification queue and took close to 30 days.
- Always opt for Aadhaar authentication, and keep each promoter's Aadhaar-linked mobile at hand
- If asked to visit a GST Suvidha Kendra, book the earliest slot and carry original documents
Mistake 4: Choosing the Wrong HSN/SAC Codes
The Problem:
A catering business listed only a restaurant service code, then started supplying packaged food to retailers. Its invoices no longer matched its registered activity.
- List codes for everything you actually supply, including what you plan to start soon
- Update the registration through a non-core amendment when your activities change
Mistake 5: Forgetting the Post-Registration Deadlines
The Problem:
Pooja got her GSTIN but never added her bank account and missed her first two returns, thinking a new registration had a grace period.
- Add bank details within 30 days or before the first GSTR-1/IFF
- File returns from the very first period — Nil returns also attract late fees
- Missing these can lead to suspension of the new registration
Part 9: Frequently Asked Questions – GST Registration 2026
Eligibility Questions
What is the GST registration limit in 2026?
₹40 lakh for businesses supplying only goods and ₹20 lakh for services in most states. Manipur, Mizoram, Nagaland and Tripura use ₹20 lakh for goods and ₹10 lakh for services, while Telangana and Puducherry use ₹20 lakh for goods. Certain businesses must register regardless of turnover.[2]
Is GST registration mandatory for selling on Amazon or Flipkart?
Generally yes, for sellers of goods. Since October 2023, small sellers below the threshold can make intra-state sales through e-commerce using a PAN-based enrolment, but inter-state sales need a GSTIN.[3]
Do freelancers need GST registration?
Yes, once aggregate turnover crosses ₹20 lakh (₹10 lakh in special category states). Export of services to foreign clients counts towards this limit.
Can I register for GST voluntarily below the threshold?
Yes. You can then claim input tax credit and sell to GST-registered buyers, but you must file all returns from registration onwards.
Can I get GST registration for a business run from home?
Yes. A residential address can be the principal place of business with an electricity bill or property tax receipt, and a consent letter if the property belongs to a family member.
Fees and Timeline Questions
What is the government fee for GST registration?
Nil. GST registration on the official portal is free. A consultant charges only a professional fee for preparing and filing the application.
How long does GST registration take?
Within three working days under Rule 14A or the Rule 9A system-based route when conditions are met. Otherwise seven working days, or up to 30 days where physical verification is required.[4]
Who can opt for Rule 14A simplified registration?
Applicants whose monthly output tax liability on supplies to registered persons will not exceed ₹2.5 lakh, including CGST, SGST/UTGST, IGST and cess. Aadhaar authentication is mandatory, and only one such registration per State/UT is allowed against a PAN.[4]
Process and Document Questions
What documents are required for GST registration?
PAN, Aadhaar and photographs of promoters, proof of the business premises, constitution documents for firms, LLPs and companies, and an authorisation for the signatory. Bank details are added after registration.
Do I need a DSC for GST registration?
Companies and LLPs must sign with a DSC. Proprietors, partnership firms and most others can submit using EVC through an OTP.
Do I need separate GST registration for each state?
Yes. Each State or UT where you have a place of business needs its own GSTIN, all linked to the same PAN.
How do I download my GST registration certificate?
Log in to gst.gov.in and go to Services → User Services → View/Download Certificates. The certificate is in Form GST REG-06.
What is the structure of a GSTIN?
A GSTIN has 15 characters: a 2-digit state code, the 10-character PAN, an entity number for that PAN in the state, the letter "Z" by default, and a check digit.
Penalty and Compliance Questions
What is the penalty for not taking GST registration?
A person liable to register who fails to do so faces a penalty of ₹10,000 or the amount of tax evaded, whichever is higher, under Section 122 of the CGST Act, plus the tax and interest.[5]
What do I need to do after getting GST registration?
Add bank details, display the certificate and GSTIN at your premises, issue GST-compliant invoices, and file returns from the first period. See our GST return filing guide for due dates.
Can GST registration be cancelled?
Yes, either on your application (for example, when the business closes) or by the officer for reasons such as not filing returns for a prescribed period. A final return in GSTR-10 is due after cancellation.
