What is GST Registration in India?
GST Registration is the process of obtaining a GSTIN (Goods and Services Tax Identification Number) from the Government of India's GST Network (GSTN). This unique 15-digit alphanumeric number is your business's identity for all GST-related transactions, return filing, and Input Tax Credit (ITC) claims.
GST replaced a complex web of indirect taxes — VAT, Service Tax, Central Excise, Entry Tax, Octroi and more — on 1 July 2017. The CGST Act, 2017 and IGST Act, 2017 govern all GST registrations, return obligations, and compliance requirements across India.
Once registered, your business gets a GSTIN that must appear on all tax invoices, e-way bills, and GST returns. Without a GSTIN, you cannot legally collect GST from customers, claim ITC on your purchases, or sell on major e-commerce platforms like Amazon, Flipkart, or Meesho.
Who Must Register for GST?
GST Registration is mandatory under the following categories as specified in Section 22 and Section 24 of the CGST Act, 2017:
- Goods Suppliers: Annual aggregate turnover exceeds Rs.40 lakhs (Rs.20 lakhs for special category states including Manipur, Mizoram, Nagaland, Tripura)
- Service Providers: Annual aggregate turnover exceeds Rs.20 lakhs (Rs.10 lakhs for special category states)
- Interstate Suppliers: Any business making taxable supply of goods or services across state borders, regardless of turnover (Section 24)
- E-Commerce Sellers: Anyone selling on Amazon, Flipkart, Meesho, Snapdeal, or any marketplace — mandatory regardless of turnover
- E-Commerce Operators: Platforms facilitating supply through their portal (liable for TCS under Section 52)
- Importers & Exporters: All businesses engaged in international trade
- Casual Taxable Persons: Occasional suppliers in states with no fixed place of business
- Non-Resident Taxable Persons: Foreign businesses making taxable supplies in India
- Agents & Input Service Distributors (ISD): Those acting as agents for a registered supplier or distributing ITC
- Voluntary Registrants: Businesses below the threshold who opt in to claim ITC and gain credibility
Types of GST Registration in India
1. Regular GST Registration
The most common type. Applicable to all businesses above the turnover threshold or mandatorily registered under Section 24. Regular registrants must file GSTR-1 (outward supplies) and GSTR-3B (monthly summary) and can claim full Input Tax Credit on all business purchases.
2. Composition Scheme Registration
Designed for small businesses with annual turnover up to Rs.1.5 crore (goods) or Rs.50 lakhs (services). Tax is paid at a flat low rate (1% for manufacturers, 2.5% for food service, 6% for services) without the right to claim ITC. Only quarterly CMP-08 and annual GSTR-4 returns are required.
3. GST Registration under Rule 14A (Suo Motu)
Initiated by the GST officer when the department identifies an unregistered person liable for GST through intelligence reports, surveys, or assessment proceedings. Regalwhiz has deep expertise in handling Rule 14A registrations and responding to Show Cause Notices (SCNs).
4. Casual Taxable Person Registration
Temporary registration (max 90 days, extendable) for businesses making occasional supplies in a state where they have no fixed establishment — e.g., participating in trade fairs, exhibitions, or pop-up events. Requires advance tax deposit before registration.
5. Non-Resident Taxable Person Registration
For foreign individuals or companies making taxable supplies in India without a fixed establishment. PAN is not mandatory (passport can be used). Valid for up to 90 days. Must apply at least 5 days before commencing supply.

Step-by-Step GST Registration Process in India
The GST registration process is entirely online on the GST Portal (gst.gov.in). Here is the detailed step-by-step process:
- Step 1 — Generate TRN: Visit gst.gov.in → Services → Registration → New Registration. Enter PAN, mobile, and email. Verify with OTPs. Receive Temporary Reference Number (TRN).
- Step 2 — Fill Part B of REG-01: Use the TRN to fill the complete application — business details, promoter details, authorised signatory, principal place of business, bank account details, and goods/services description with HSN/SAC codes.
- Step 3 — Upload Documents: Upload scanned copies of all required documents including address proof, identity proof, and photographs within the specified file size limits (JPEG/PDF, max 1MB each).
- Step 4 — Aadhaar Authentication: The authorised signatory must complete Aadhaar e-KYC via OTP verification. This is mandatory for all regular registrations and determines whether the application gets auto-approved or goes for officer verification.
- Step 5 — ARN Generation: Upon successful submission, an Application Reference Number (ARN) is generated via SMS and email. The ARN allows you to track the application status on the GST portal.
- Step 6 — Officer Verification (if required): If Aadhaar authentication is successful, the application is typically auto-approved. If not, a GST officer reviews the application within 7 days. The officer may raise queries (GSTR-REG-03) requiring clarification within 7 working days.
- Step 7 — GSTIN Issuance: Once approved, the GSTIN and GST Registration Certificate (Form GST REG-06) are issued and available for download on the GST portal.

Common GST Registration Mistakes to Avoid
- Incorrect Business Category: Selecting the wrong business type (Proprietorship vs. Company) leads to application rejection and delays
- Mismatched PAN Details: Business name on the GST application must exactly match the name on the PAN card — any mismatch causes rejection
- Wrong HSN/SAC Codes: Incorrect HSN codes for goods or SAC codes for services lead to compliance issues in return filing
- Incomplete Address Proof: Address proof must be recent (within 3 months) and clearly show the business address matching the application
- Aadhaar Mismatch: The Aadhaar number linked mobile must be active for OTP verification. An inactive or mismatched number delays the process significantly
- Not Tracking Officer Queries: If the GST officer raises a query (REG-03), you have only 7 working days to respond. Missing this deadline leads to rejection
- Registering Under Wrong Jurisdiction: GST registration must be in the state where the principal place of business is located, not just the home state of the owner
GST Registration — Quick FAQs
Can I have multiple GST registrations for my business?
Yes. If your business operates in multiple states, you must register separately in each state. You can also have multiple registrations within one state if you have multiple business verticals (e.g., manufacturing + services + trading). Each registration is treated as a distinct taxable person with its own GSTIN.
What is an ARN in GST registration?
ARN (Application Reference Number) is a unique 15-character reference number generated upon successful submission of your GST registration application on the GST portal. It is used to track the application status. The ARN is NOT your GSTIN — the GSTIN is issued only after the application is approved by the GST officer.
What is the penalty for late GST registration?
If you were liable to register but didn't, the penalty is Rs.10,000 or 10% of the tax evaded — whichever is higher. For deliberate evasion, the penalty equals 100% of the tax amount. Additionally, you become liable to pay all the GST that should have been collected, along with 18% annual interest on the unpaid amount.
Does GST registration help for government tenders?
Yes. Most government tenders (GeM portal, state government procurement, PSU contracts) require bidders to have a valid GSTIN. GST registration alongside Company Registration significantly improves your eligibility for government contracts and public sector business.
What is the connection between GST Registration and Company Registration?
They are separate registrations. Company Registration under the Companies Act 2013 creates your legal entity (Pvt. Ltd., OPC, LLP). GST Registration is a tax registration under the CGST Act. Most new businesses need both — Regalwhiz handles both registrations as a bundled package.
Is FSSAI registration connected to GST registration for food businesses?
They are separate but complementary. Food businesses need both FSSAI Registration (food safety license) and GST Registration (tax compliance). Regalwhiz helps food businesses get both registrations together, ensuring complete legal compliance from day one.
