Get your GSTIN in 3–7 days

Category: GST Services. From ₹999. Typical timeline: 3–7 days.

Overview

GST registration gives a business a unique 15-digit GSTIN under the CGST Act, 2017, allowing it to legally collect GST from customers, claim input tax credit on purchases, and trade across state lines without restriction. Registration is done entirely online on the GST portal in two parts — Part A generates a Temporary Reference Number (TRN) via PAN, mobile and email OTP, and Part B collects business and bank details along with supporting documents.

Who needs it

• Businesses that have crossed the mandatory turnover threshold
• E-commerce sellers listing on Amazon, Flipkart, Meesho and similar platforms
• Exporters who want to claim a GST refund or file a Letter of Undertaking (LUT)
• Any business that wants to claim input tax credit on its purchases before hitting the mandatory threshold

Eligibility

• Mandatory once aggregate turnover crosses ₹40 lakh for goods suppliers (₹20 lakh in special category states)
• Mandatory once aggregate turnover crosses ₹20 lakh for service suppliers (₹10 lakh in special category states)
• Mandatory regardless of turnover for inter-state suppliers, e-commerce sellers, casual taxable persons, non-resident taxable persons, and anyone liable under reverse charge
• Voluntary registration is open to any business below the threshold that wants to claim input tax credit

Documents required

• PAN card of the business and the authorized signatory
• Aadhaar card of the authorized signatory (used for e-KYC/Aadhaar authentication)
• Proof of business constitution — Certificate of Incorporation, LLP Agreement, or Partnership Deed as applicable
• Address proof of the principal place of business (electricity bill/property tax receipt + rent agreement or NOC)
• Bank account proof — a cancelled cheque or the first page of a bank statement showing account number, IFSC and account holder name
• Passport-size photograph of the authorized signatory
• Digital Signature Certificate (mandatory for companies and LLPs; individuals/proprietors can use Aadhaar e-signature/EVC instead)
• Board resolution or letter of authorisation appointing the authorized signatory (for companies and LLPs)

Process

1. Part A — TRN generation — Submit PAN, mobile number and email; OTP verification on both generates a 15-digit Temporary Reference Number valid for 15 days.
2. Part B — Application filing — Using the TRN, submit business details, promoter/partner details, principal place of business, bank account and upload all supporting documents; this generates an Application Reference Number (ARN).
3. Aadhaar authentication — The authorized signatory completes Aadhaar e-KYC authentication (or opts for physical verification), which determines the processing timeline.
4. Department review — A GST officer reviews the application — either approves it directly, or raises a clarification query (Form REG-03) that must be answered within 7 working days.
5. GSTIN & certificate issuance — On approval, the GST Registration Certificate (Form REG-06) is issued with the GSTIN, effective from the date of application (or an earlier date for voluntary registration granted from the incorporation date).

Government fees

• Government fee: Nil — GST registration itself carries no government fee
• DSC (per authorized signatory, if required): ₹1,499 — see our Digital Signature Certificate service

Professional fee

₹999 professional fee, covering application preparation, document review and query handling if the department raises one.

Timeline

3–7 working days when Aadhaar authentication is completed and no clarification is raised. If the officer raises a query (REG-03), it can extend to 15–20 working days depending on how quickly the response is filed.

Frequently asked questions

Is GST registration compulsory for my business?

It is mandatory once your aggregate turnover crosses ₹40 lakh for goods (₹20 lakh for services), or immediately if you sell inter-state, sell via e-commerce, or fall under reverse charge — regardless of turnover.

Can I register voluntarily before crossing the threshold?

Yes. Voluntary registration is common among businesses that want to claim input tax credit or deal with GST-registered clients who prefer registered vendors.

Do I need to visit a GST office in person?

No — the entire process is online. Physical verification is only triggered in specific risk-based cases flagged by the department.

What happens if I don’t register despite crossing the threshold?

A penalty of 10% of the tax due (minimum ₹10,000) applies for a genuine oversight, rising to 100% of the tax due if deliberate tax evasion is established.

Can I cancel my GST registration later?

Yes, via an application for cancellation on the GST portal, along with a final return (GSTR-10), if your business closes or turnover falls below the threshold and you no longer want to remain registered.

Common mistakes

• Submitting an address proof that doesn’t match the rent agreement or NOC exactly, triggering a REG-03 query
• Selecting the wrong HSN/SAC code, which can affect the applicable tax rate and later invite scrutiny
• Missing the 7-working-day window to respond to a department clarification, which leads to automatic rejection
• Registering under the regular scheme when the Composition Scheme (for turnover under ₹1.5 crore) would reduce compliance burden and tax outflow
• Not linking the correct bank account, causing refund and reconciliation issues later

Penalties for non-compliance

• Failure to register despite crossing the threshold: 10% of tax due (minimum ₹10,000), or 100% of tax due if deliberate evasion is established
• Late GSTR-3B filing: late fee of ₹50/day (₹25 CGST + ₹25 SGST), or ₹25/day for nil returns, plus 18% p.a. interest on tax due
• Non-filing of returns for 6 consecutive months can lead to suo-motu cancellation of the GSTIN by the department

Legal references

• CGST Act, 2017 — Sections 22 to 30 (registration, amendment, cancellation)
• CGST Rules, 2017 — Rules 8 to 26 (registration procedure)
• Notification-based threshold limits under Section 22, as amended from time to time
