How to Get GST Registration in India
Obtaining Goods and Services Tax (GST) registration in India is a mandatory requirement for businesses exceeding the prescribed turnover threshold, dealing with inter-state supplies, or operating as e-commerce sellers and aggregators. The process runs entirely through the GST Common Portal, but strict adherence to documentation standards remains critical under the CGST Act, 2017 as amended. Even a minor mismatch between your PAN details and the application form can trigger a notice or outright rejection, so preparation matters as much as the filing itself. This guide walks regular taxpayers through the full journey from eligibility assessment to receiving an active GSTIN, and flags the checkpoints where applications most commonly stall. Whether you are a first-time founder, a manufacturer expanding across states, or an existing business voluntarily opting in for Input Tax Credit, the steps below reflect the current 2026 workflow on the portal.
Before you start
- Valid PAN Card of the business entity or proprietor
- Aadhaar of the authorised signatory (for e-KYC/Aadhaar authentication route)
- Proof of Principal Place of Business (electricity bill, property tax receipt, or rent/lease agreement with NOC)
- Bank Account Details with a cancelled cheque, bank statement, or passbook first page
- Constitution documents (Partnership Deed, LLP Agreement, or Certificate of Incorporation with MOA/AOA, as applicable)
- Digital Signature Certificate (mandatory for companies and LLPs; optional for proprietorships)
- Passport-size photograph of proprietor/partners/directors and authorised signatory
- Board resolution or authorisation letter appointing the authorised signatory (for companies/LLPs)
Step-by-step
Determine liability and registration category
Check whether your aggregate turnover crosses the applicable threshold — commonly cited as ₹40 lakh for goods suppliers and ₹20 lakh for services (with lower ₹10 lakh/₹20 lakh thresholds in Special Category States) — or whether you fall into a mandatory-registration category regardless of turnover, such as inter-state suppliers, e-commerce operators, or those liable under reverse charge.
Thresholds and category rules are periodically revised by GST Council notifications, so confirm the figures applicable to your state and business type before proceeding — do not rely solely on figures from an earlier filing cycle.
Gather and digitise documents
Compile PAN, Aadhaar, address proof, bank proof, constitution documents, and photographs in the file formats and size limits specified by the portal (typically PDF/JPEG under a few MB per document). Poor-quality scans are one of the most frequent causes of processing delay, so use clear, uncropped copies.
Login and initiate Part A of the application
Access the official GST Common Portal (gst.gov.in), go to Services > Registration > New Registration, and enter your legal name (as per PAN), PAN, email, and mobile number. You will receive OTPs on both the email and mobile for verification, after which a Temporary Reference Number (TRN) is generated.
The TRN is typically valid for a limited window (commonly around 15 days) — complete Part B of the application within that period or you will need to restart Part A.
Complete Part B — Form GST REG-01
Log in again using the TRN and complete the detailed application: business constitution, principal and additional places of business, details of goods/services (HSN/SAC codes), promoters/partners/directors, authorised signatory, and bank account details.
Ensure every field — especially legal name, date of birth, and PAN — matches source documents exactly. Discrepancies here are the single largest driver of rejections and clarification notices.
Upload supporting documents
Attach scanned copies of the constitution proof (Partnership Deed/Incorporation Certificate/MOA-AOA), address proof, bank account proof, and identity/address proof of promoters and the authorised signatory. Non-resident taxable persons and certain other categories may need additional forms beyond the standard REG-01 flow — confirm your category before submission if you fall outside straightforward domestic registration.
Complete Aadhaar authentication or opt for biometric verification
Where offered, complete Aadhaar e-KYC authentication for the promoters/authorised signatory, as this can shorten processing time. If Aadhaar authentication is not opted for, is unsuccessful, or the officer flags the case for physical verification, you may be directed to a GST Suvidha Kendra for biometric authentication and document verification, which can extend the overall timeline.
Sign and submit the application
Verify all entered data carefully, then sign using DSC (mandatory for companies/LLPs) or e-Sign/EVC (permitted for other entity types). On successful submission you receive an Application Reference Number (ARN) by SMS and email — retain this for tracking status.
Respond to any query raised by the proper officer
If the officer is satisfied, the application proceeds without further contact. If a discrepancy is found, you may receive a notice in Form GST REG-03 seeking clarification — you typically get a short statutory window (commonly around 7 working days) to respond in Form GST REG-04 with the requested clarification or corrected documents. Failing to respond in time can lead to rejection under Form GST REG-05.
Track ARN status and receive the GSTIN
Monitor the application status on the portal using the ARN. Since the Rule 14A fast-track scheme took effect, applicants who complete Aadhaar authentication and are assessed as low-risk (broadly, smaller applicants with limited projected monthly B2B output tax liability) can receive automated approval within about 3 working days. Applications outside that route, or those requiring physical/biometric verification or that raise queries, follow the standard timeline and can take longer. On approval, the system issues the Registration Certificate in Form GST REG-06 containing your unique 15-digit GSTIN, available for download from the portal — confirm your eligibility for the fast-track route on the portal, as the qualifying criteria are subject to periodic revision.
Complete post-registration compliance setup
Once active, display your GSTIN certificate and GST number at the principal place of business, update your GSTIN on invoices and letterheads, and set up your return-filing cadence (GSTR-1, GSTR-3B, and applicable annual returns) based on your turnover and scheme (regular vs QRMP). Confirm the current return-filing and annual return requirements applicable to your turnover slab, as these are revised periodically.
Common mistakes to avoid
- Mismatch between the legal name or date of birth on PAN and the details entered in the application form
- Submitting blurry, cropped, or outdated address-proof documents that fail verification
- Allowing the TRN to lapse by not completing Part B within the validity window
- Providing a bank account not yet operational or with mismatched account-holder name
- Missing the response window for a Form GST REG-03 clarification notice, leading to rejection
- Selecting the wrong constitution of business (e.g., proprietorship instead of partnership), causing downstream document mismatches
- Using an incorrect or outdated HSN/SAC code that misrepresents the nature of goods or services supplied
- Assuming voluntary registration has no ongoing compliance burden — return filing obligations apply regardless of how registration was triggered
Frequently asked questions
Can I register if my turnover is below the threshold?
Yes, voluntary registration is permitted for businesses below the applicable threshold, commonly done to claim Input Tax Credit (ITC), supply across state lines, or meet a customer's vendor-onboarding requirement. Once registered voluntarily, however, standard compliance obligations — including timely return filing — apply just as they would to a mandatorily registered taxpayer.
How long does the approval process take in 2026?
Where the application qualifies for the Rule 14A fast-track route (Aadhaar-authenticated, assessed low-risk), automated approval can come within about 3 working days. Other Aadhaar-authenticated applications are typically approved within a few working days. If the application is flagged for physical verification or a clarification notice is issued, the process can extend to two to three weeks or more depending on jurisdiction workload. Track your ARN status on the portal for the current stage of your specific application.
Is there a government fee for GST registration?
No — self-registration on the official GST portal (gst.gov.in) does not carry any government fee; it is free of cost. Professional CA/CS firms charge separate consultation and filing fees which vary based on entity complexity — confirm the current fee schedule with your service provider rather than assuming a fixed figure.
What happens if my application is rejected?
You will receive a rejection order (Form GST REG-05) stating the reasons, typically following an unanswered or unsatisfactory response to a clarification notice. You can file a fresh application correcting the identified issues, or pursue an appeal through the prescribed appellate process — confirm current appeal timelines and forms, as procedural rules are updated periodically.
Do I need to register separately in every state where I operate?
Yes — unlike a single PAN-based tax number, GST registration is state-wise. If your business has a place of operation, warehouse, or is otherwise liable to register in multiple states, you generally need a separate GSTIN for each state, even though all registrations link back to the same PAN.
Can I start invoicing before receiving the GSTIN?
No. You should not charge or collect GST on invoices until your registration is approved and the GSTIN is active. Businesses expecting to cross the threshold or that require registration in advance of a known transaction should apply early enough to have the GSTIN in hand before invoicing begins.
Is Aadhaar authentication mandatory for registration?
It is not strictly mandatory in every case, but opting for Aadhaar authentication of the promoters and authorised signatory generally streamlines processing. Applicants who skip it, or for whom authentication fails, are more likely to be routed to physical/biometric verification at a GST Suvidha Kendra, which adds time to the process.
What is the difference between regular registration and composition scheme registration?
Regular registration allows you to charge GST on outward supplies and claim Input Tax Credit on purchases, with standard periodic return filing. The composition scheme, available to eligible small taxpayers below a specified turnover cap, involves a simplified flat-rate payment and reduced compliance but disallows ITC claims and inter-state outward supply in most cases. Confirm current eligibility caps before choosing between the two.
Do I need a Digital Signature Certificate to register?
Companies and LLPs are required to sign the application using a Class 3 DSC of the authorised signatory. Proprietorships and certain other entity types can instead use e-Sign (Aadhaar-based) or EVC (OTP-based electronic verification code) in place of a DSC.
Can PNPC Global handle the entire registration process on my behalf?
Yes. PNPC Global's team prepares and reviews your documentation, files the application on the GST Portal, tracks the ARN, and handles any clarification notices raised by the proper officer, so you receive an active GSTIN with minimal back-and-forth.
What if I already have a GSTIN in one state and open a branch in another?
You need to apply for a fresh GSTIN in the new state as a distinct registration, using the same PAN. The new registration is treated as a separate 'distinct person' for GST purposes, with its own return-filing obligations.
Can registration be cancelled or surrendered later if the business closes?
Yes, registered taxpayers can apply for cancellation of GST registration when the business ceases operations, is transferred, or no longer meets the criteria for registration. A final return (GSTR-10) is generally required after cancellation is approved — confirm the current form and deadline applicable at the time of surrender.
