GST Registration in IndiaGet Your GSTIN Online

GST registration is the process through which a business or individual supplier obtains a unique 15-digit Goods and Services Tax Identification Number (GSTIN) from the Government of India via the GST Common Portal (gst.gov.in). The GSTIN is the business's legal identity under the GST framework — it authorises the business to collect GST from customers, claim Input Tax Credit (ITC) on purchases and expenses, and file statutory returns with the Central Board of Indirect Taxes and Customs (CBIC).

Under Section 22 of the Central Goods and Services Tax Act, 2017, registration is compulsory for every supplier whose aggregate annual turnover in a financial year exceeds the prescribed threshold — ₹40 lakh for suppliers of goods (general category states), ₹20 lakh for service providers (general category states), and ₹10 lakh for businesses operating in special category states including Manipur, Mizoram, Nagaland, Tripura, Uttarakhand, Sikkim, Himachal Pradesh, and Jammu & Kashmir. Beyond turnover, Section 24 of the CGST Actmandates registration for certain categories of suppliers regardless of turnover — including inter-state suppliers, e-commerce operators and sellers, casual taxable persons, non-resident taxable persons, and businesses paying tax under the reverse charge mechanism (RCM).

Operating a business liable for GST without valid registration is a serious legal offence. Under Section 122 of the CGST Act, the penalty for failure to register is 100% of the tax amount due (with a minimum penalty of ₹10,000 even if the tax liability is lower). Interest on unpaid GST accrues at 18% per annum from the date it was originally due. In cases of deliberate, wilful evasion involving amounts exceeding ₹5 crore, Section 132 provides for criminal prosecution and imprisonment up to 5 years. Beyond legal compliance, a GSTIN is practically essential — major B2B buyers, government e-procurement portals (GeM), e-commerce marketplaces (Amazon, Flipkart, Meesho), and banks (for current account opening) require GSTIN verification before transacting.

The most significant financial benefit of registration is access to the Input Tax Credit mechanism. Once registered, a business can offset GST paid on business inputs — raw materials, stock, capital goods, services like freight, rent, and professional fees — against the GST it collects on sales. This eliminates the cascading tax-on-tax effect and directly reduces your net GST payable. For businesses with substantial purchase costs, ITC claims often reduce effective tax outgo by 40–70%, making the cost of registration and compliance a fraction of the savings.

The GST framework recognises several distinct registration types, each designed for different categories of taxpayers. Choosing the correct type at the outset is critical because it determines your applicable GST rates, ITC eligibility, invoice format, return filing frequency, and overall compliance obligations. Switching from one scheme to another — for example, from Composition to Regular — requires filing Form CMP-04 and involves a transition of your ITC position, so making the right choice initially saves significant complexity later.

Regular GST Registration is the default and most common form for businesses across India. Regular taxpayers issue GST-compliant tax invoices, charge GST at applicable rates (5%, 12%, 18%, 28%) to customers, file GSTR-1 to report outward supplies, and file GSTR-3B to declare net GST liability and make tax payments. They are fully entitled to claim Input Tax Credit on all business inputs subject to restrictions under Section 17 of the CGST Act. Regular registration is the appropriate choice for all B2B businesses, exporters, manufacturers, traders with significant input costs, and anyone whose buyers need a GST invoice to claim their own ITC.

The Composition Scheme (Section 10 of CGST Act) is available to suppliers with aggregate annual turnover up to ₹1.5 crore (₹75 lakh for special category states; ₹50 lakh for eligible service providers under the amendment). Flat reduced tax rates apply: 1% for traders, 2% for manufacturers, 5% for restaurant and food service businesses, and 6% for eligible service providers. Key restrictions: Composition dealers cannot issue tax invoices (only bills of supply), cannot collect GST from customers, cannot claim ITC, and cannot make inter-state outward supplies of goods. Compliance is significantly lighter — only a quarterly payment challan (CMP-08) and an annual return (GSTR-4). This is the right choice for small local retailers, manufacturers, and service providers with predominantly B2C customers and minimal input costs.

Casual Taxable Person (CTP) registration under Section 27 applies to businesses making temporary taxable supplies in a state where they have no fixed place of business — for example, a business exhibiting products at a trade fair or exhibition in another state. CTP registration is valid for a maximum of 90 days (extendable on application), requires an advance deposit of estimated GST liability at the time of filing the application, and must be obtained before the first supply is made in that state.

E-Commerce sellers — individuals and businesses selling goods or services through marketplace platforms including Amazon, Flipkart, Myntra, Meesho, Swiggy, and Zomato — must obtain GST registration regardless of their annual turnover. These platforms are required under Section 52 of the CGST Act to collect TCS (Tax Collected at Source) at 1% of net value of taxable supplies before disbursing sales proceeds to sellers. A valid GSTIN is also a mandatory prerequisite for seller onboarding on every major e-commerce platform.

Input Service Distributor (ISD) registration allows a head office or corporate headquarters that receives invoices for common input services — such as enterprise software licences, group insurance, rent for shared premises, or centralised professional services — to distribute the ITC proportionately across its branches through Form GSTR-6. ISD registration is a separate registration from regular GST registration and is particularly relevant for multi-location businesses with centralised procurement functions.

Obtaining your GSTIN is only the first milestone. Every GST-registered regular taxpayer has ongoing statutory compliance obligations that must be met each month or quarter to avoid penalties and protect ITC entitlements.

GSTR-1 (outward supply return) must be filed by the 11th of the following month for monthly filers. Businesses with aggregate turnover up to ₹5 crore who opt for the QRMP (Quarterly Return Monthly Payment) scheme file GSTR-1 quarterly by the 13th of the month following the quarter, with an optional Invoice Filing Facility (IFF) for months 1 and 2 of each quarter. GSTR-3B (summary return with tax payment) is due by the 20th of the following month for most taxpayers (22nd/24th for QRMP quarterly filers, varying by state). Missing either return attracts a late fee of ₹50 per day (₹20 per day for nil returns) plus 18% per annum interest on any unpaid GST.

ITC reconciliation with GSTR-2B is a critical monthly discipline. GSTR-2B is an auto-populated statement reflecting ITC available based on your suppliers' GSTR-1 filings. Under Rule 36(4) of the CGST Rules, ITC claims beyond GSTR-2B are capped at 5% of eligible credit appearing therein — meaning a supplier who fails to file GSTR-1 directly reduces your claimable ITC. Taxvio's return filing service includes automated supplier compliance monitoring and monthly ITC mismatch analysis to protect your credit entitlements.

For businesses with aggregate annual turnover exceeding ₹2 crore, GSTR-9(annual return) must be filed by 31 December each year. Businesses above ₹5 crore must additionally file GSTR-9C — a reconciliation statement audited and certified by a Chartered Accountant. Exporters must file their LUT (Letter of Undertaking under Rule 96A) at the start of each financial year to export without upfront payment of IGST. And businesses with aggregate turnover exceeding ₹5 crore must implement e-invoicing — generating an IRN (Invoice Reference Number) and QR code for every B2B invoice via the Invoice Registration Portal (IRP) before the invoice is issued to the buyer.

Taxvio provides the complete GST compliance lifecycle in a single, affordable package: registration → monthly GSTR-1 and GSTR-3B → GSTR-9 annual return → ITC reconciliation → LUT filing → GST refund claims → notice replies → e-invoicing setup. Our goal is to make GST compliance invisible to you — so you can focus entirely on running your business.
