Ideal for businesses requiring only GST certificate Designed for new businesses starting their GST compliance journey Tailored for businesses that want hassle-free, year-round GST compliance GST Registration is the process of obtaining a 15-digit Goods and Services Tax Identification Number (GSTIN) from the Tamil Nadu authorities and CBIC, which legally allows a business to collect GST, issue tax invoices, and claim input tax credit. It replaces the earlier VAT/Service Tax/Excise regime with a single indirect tax administered jointly by the Centre and the Tamil Nadu Commercial Taxes Department. Beyond legal compliance, GST registration helps businesses reduce costs, improve credibility, expand into new markets and unlock government and financial opportunities. Claim GST paid on rent, raw materials, software, equipment and other business purchases, reducing your overall tax cost. Legally collect GST and issue valid tax invoices required by corporate clients and large enterprises. Register as a seller on Amazon, Flipkart, Meesho and other online marketplaces. Expand across India and export products without GST registration becoming a business limitation. Become eligible for government tenders, vendor registrations and industrial procurement opportunities. Improve credibility with banks and NBFCs when applying for working capital and business finance. Prevent penalties, interest and retrospective tax liabilities by registering within the prescribed limits. GST registration remains valid for life unless voluntarily surrendered or cancelled by the department. Aggregate turnover is calculated on an all-India, same-PAN basis. If your Chennai head office also has a branch in Coimbatore or a warehouse in Trichy, add up turnover across every location under the same PAN before checking whether you've crossed the limit not just the Tamil Nadu portion. Any inter-state taxable supply of goods — a Tiruppur garment exporter selling to a buyer outside Tamil Nadu must register even at Rs.2 lakh turnover Casual taxable persons and non-resident taxable persons — for example, a stall at a Chennai Trade Centre exhibition Persons liable to pay tax under reverse charge E-commerce operators, and sellers supplying through an e-commerce operator required to collect tax at source Input Service Distributors (ISD) Agents supplying goods or services on behalf of another registered person OIDAR service providers supplying from outside India to a person in Tamil Nadu Every person required to deduct tax at source (TDS) under GST Once you become liable to register, the law gives you 30 days from the date you cross the threshold (or become liable under one of the categories above) to apply. Casual taxable persons must apply at least five days before commencing business. Missing this window is what triggers the penalty covered in the Cost section below. Send us the following documents and our experts will handle the registration process. Address proof is where most GST applications get delayed, so we verify every document before filing. TANGEDCO EB bills carrying an old or abbreviated address that doesn't match the address typed into the application. We match the address exactly as printed on the bill before submission. From document verification to GSTIN issuance, our experts manage the entire registration process while keeping you informed at every stage. We evaluate your turnover, business activity and determine whether GST registration is mandatory or voluntary. Address proof and business documents are verified in the exact format expected by Tamil Nadu GST officers before filing. We prepare Form GST REG-01, select the correct HSN/SAC codes and complete Aadhaar authentication support. If Form GST REG-03 is issued, we prepare and submit the REG-04 response within the prescribed timeline. Once approved, we immediately share your GST Registration Certificate (REG-06) and 15-digit GSTIN. Need GST registration using a virtual office? We also provide virtual office solutions for businesses that don't want to lease commercial space solely for registration. Part A of GST REG-01 is submitted using PAN, mobile number and email verification to generate a Temporary Reference Number (TRN). Business details, promoters, bank account information and supporting documents are uploaded. Authentication is completed through OTP or biometric verification at the GST Seva Kendra whenever required. The application is submitted using DSC (mandatory for Companies & LLPs) or EVC, generating the ARN. The GST officer reviews the application and may issue Form GST REG-03 if clarification is required. After approval, Form GST REG-06 and your permanent 15-digit GSTIN are generated. Every GSTIN is a 15-character alphanumeric code, and the first two digits identify the state of registration. A business registered in Tamil Nadu will always have a GSTIN beginning with the state code 33. Digits 1–2: State code — 33 for Tamil Nadu Digits 3–12: The 10-character PAN of the business or proprietor Digit 13: Entity/registration count against that PAN in the state Digit 14: Default alphabet 'Z' Digit 15: Checksum digit for validation This decides who handles your future notices, refunds and audits — and it isn't something you choose. In Chennai, Central jurisdiction runs through the Chennai GST and Central Excise Zone under CBIC, split into the Chennai North, Chennai South and Chennai Outer Commissionerates, plus separate Commissionerates for Coimbatore, Madurai, Tiruchirappalli, Salem and other regional centres. On the state side, jurisdiction runs through the Tamil Nadu Commercial Taxes Department, organised into Assessment Circles across every district. Once your registration is approved, you're administratively split between Central and State jurisdiction using a formula set by the GST Council: roughly 90% of taxpayers with turnover up to Rs.1.5 crore go to State jurisdiction and 10% to Central; above Rs.1.5 crore, the split is 50:50. Both authorities retain power to act when needed. Your exact jurisdiction — Commissionerate/Circle, Division/Ward — is printed on your Registration Certificate; check it as soon as your GSTIN is issued. Official jurisdiction lists for Chennai are published by the department at gstchennai.gov.in, and state jurisdiction details are available on the Tamil Nadu Commercial Taxes Department portal, which is also available in Tamil for applicants who prefer it. Display the GST Registration Certificate at your principal place of business and every additional place of business Mention your GSTIN on every tax invoice, with the correct place-of-supply and HSN/SAC codes File GST returns on schedule, monthly or under QRMP for eligible small taxpayers, even a Nil return is mandatory when there's no activity Generate e-way bills for movement of goods above the prescribed consignment value Track turnover against the threshold every year so voluntary registration doesn't lapse into non-compliance once it becomes mandatory E-way bill threshold for movement within Tamil Nadu is Rs.1,00,000, not the Rs.50,000 national default. Tamil Nadu is one of the states that has fixed a higher intra-state limit, so goods moving entirely inside the state only need an e-way bill above Rs.1 lakh; inter-state movement still follows the Rs.50,000 threshold. Worth verifying against the current Tamil Nadu Commercial Taxes Department notification before publishing an exact figure, since state notifications are revised periodically. Furnish your bank account details within 30 days of registration, or before filing your first GSTR-1/IFF, whichever is earlier. Under Rule 10A of the CGST Rules, GSTN now auto-suspends a new GSTIN if this isn't done — the registration certificate and GSTIN alone are no longer enough to stay active. Add bank details via a non-core amendment on the portal (Services → Registration → Amendment of Registration). Based on the pattern of officer queries across our Tamil Nadu filings, most delays come down to a handful of avoidable errors: Address on the application doesn't exactly match the EB bill, property tax receipt, or rental agreement submitted as proof Rented premises without a landlord NOC, or an unregistered/unstamped rental agreement Name mismatch between Aadhaar, PAN and the application — even a minor spelling difference triggers a manual query Incorrect or overly broad HSN/SAC code selection that doesn't reflect the actual business activity Photograph not meeting the portal's file size or format specification Missing board resolution or authorisation letter for the signatory, for companies and LLPs Bank details submitted before the account is actually opened in the business's name We check every one of these before your application goes in, which is why our filings rarely draw a REG-03 query. Small traders, restaurants and local manufacturers in Tamil Nadu often qualify for the composition scheme — a simpler, lower-compliance option for businesses that don't need input tax credit or inter-state sales. We've filed GST registrations for proprietorships, partnerships, LLPs and companies across Chennai, Coimbatore, Madurai, Tiruchirappalli, Salem, Tiruppur and Erode, working directly with both the Tamil Nadu Commercial Taxes Department and CBIC's Chennai and regional Commissionerates. The government portal is free, what you're paying for is getting it right the first time. 19+ years in business compliance, a Chennai headquarters, and 1 lakh+ customers served, local expertise at a scale you can trust. Dedicated GST practitioner assigned to your application Transparent, upfront pricing, no charges added after you've started Address-proof and HSN/SAC codes checked against known Tamil Nadu rejection patterns before filing Support continues after registration, returns, amendments, notices and cancellations, all under one roof We register businesses across every district of Tamil Nadu, filing with the correct local jurisdiction in each case. A few of the industry clusters we work with most often: Tamil Nadu's largest business hub, with dense automobile, IT/ITES and manufacturing activity across the metro area. We file directly with the Chennai North, South and Outer Commissionerates and the relevant Commercial Taxes Department circle based on your business address. A major engineering, textile machinery and pump manufacturing centre. Manufacturers here often deal with inter-state buyers, which triggers compulsory GST registration regardless of turnover. A regional trade, retail and wholesale distribution hub for southern Tamil Nadu. We assist traders and distributors with both regular and composition scheme registration. A centre for engineering goods, public sector manufacturing and trading businesses. Our team files registrations for both established manufacturers and new small businesses in the region. Known for steel, textiles and agro-based industries. We handle registration for manufacturing units as well as service businesses supporting them. India's knitwear and hosiery export hub. Because exports are treated as inter-state supply, Tiruppur exporters need GST registration irrespective of turnover — we also assist with LUT filing for zero-rated exports. A centre for textiles, turmeric trade and allied agro-commerce. We support both textile units and agri-trading businesses with registration and ongoing compliance. A retail, trading and port-linked export corridor in southern Tamil Nadu. We assist export-oriented businesses here with GST registration alongside IEC and other cross-border trade compliances.

Frequently Asked Questions
What is the turnover limit for GST registration in Tamil Nadu?
Rs.40 lakh for suppliers of goods and Rs.20 lakh for suppliers of services or mixed suppliers, since Tamil Nadu is a normal category state. Businesses under compulsory-registration categories — inter-state supply, e-commerce, reverse charge, casual taxable persons and others — must register regardless of turnover.Is GST registration compulsory for small shops and traders in Tamil Nadu?
Only once annual turnover crosses Rs.40 lakh for goods (or Rs.20 lakh where services are also supplied), or if the trader falls under a compulsory-registration category. Below that, registration is voluntary, though many small traders register anyway to claim input tax credit and supply to GST-registered buyers.How long does GST registration take in Tamil Nadu?
Around 3–7 working days where Aadhaar authentication is completed successfully and no risk flags are raised. Applications routed for physical or biometric verification can take up to 30 working days.How many days do I have to apply after becoming liable for registration?
30 days from the date you become liable to register. Casual taxable persons must apply at least five days before commencing business in Tamil Nadu.Which documents are most often rejected during GST registration in Tamil Nadu?
Address proof is the most common cause — EB bills or property tax receipts that don't exactly match the address typed into the application, and rental agreements submitted without a landlord's NOC.Is there a government fee for GST registration?
No. Registration on the GST portal itself is free. Professional fees apply only if you engage a consultant such as Kanakkupillai to prepare and file the application on your behalf — ask us for a quote based on your business type.What is the e-way bill limit for moving goods within Tamil Nadu?
Rs.1,00,000 for intra-state movement, higher than the Rs.50,000 national default that applies to inter-state movement. Verify the current notification before relying on this for a live shipment decision.Will my GST registration be handled by the Tamil Nadu Commercial Taxes Department or by the Centre?
It depends on which jurisdiction your application is assigned to under the Centre-State division formula — broadly 90% State / 10% Central for turnover up to Rs.1.5 crore, and 50:50 above that. Your specific Ward/Circle (State) or Range/Division (Central) is printed on your Registration Certificate.What does the 33 at the start of a Tamil Nadu GSTIN mean?
It's the state code assigned to Tamil Nadu under GST. Every GSTIN issued to a Tamil Nadu-registered business begins with 33, followed by the applicant's 10-digit PAN and additional checksum characters.Does a Tiruppur exporter selling only outside India need GST registration below Rs.20 lakh turnover?
Yes. Export of goods or services is treated as an inter-state (zero-rated) supply under GST, and inter-state supply is a compulsory-registration trigger irrespective of turnover.We Provide Best Quality
