GST registration in Chennai is a fully online process on the GST portal. A business in Tamil Nadu must register once annual turnover crosses ₹40 lakh for goods or ₹20 lakh for services. Online sellers and inter-state suppliers of goods need it from day one, whatever their turnover. The government fee is ₹0, approval usually takes 3 to 7 working days, and ComplyLocal's fee starts at ₹1,999.

What Is GST Registration?
GST registration is the process of enrolling your business under the Goods and Services Tax. Once registered, your business receives a GSTIN, a unique 15-digit Goods and Services Tax Identification Number. This number is your business identity under GST. You need it to collect tax from customers, claim input tax credit on purchases and file GST returns.
The first two digits of a GSTIN show the state of registration. Tamil Nadu's code is 33, so every GSTIN issued in Chennai begins with 33, followed by the PAN of the business.
Running above the threshold without registration is costly. The penalty is 10% of the tax due, with a minimum of ₹10,000. It rises to 100% where tax is deliberately evaded.
Who Needs GST Registration in Chennai?
You need GST registration in Chennai if your aggregate turnover crosses ₹40 lakh (goods) or ₹20 lakh (services) — or immediately, with no threshold benefit, if you fall in a mandatory category below.

GST Registration Guide for Chennai Businesses
Chennai businesses come to GST from very different directions, and we plan each registration around that.
Exporters are the biggest local pattern. With Chennai Port and the airport cargo complex at the doorstep, the city has thousands of goods and service exporters. Exports are zero-rated under GST, but registration is still required. Filing a Letter of Undertaking (LUT) on top of it lets you export without paying IGST, and we set up LUT filing along with the registration.
Manufacturers and auto ancillaries in Ambattur, Guindy, Sriperumbudur and Oragadam mostly sell B2B across states. For them, registration is compulsory from the first inter-state invoice, whatever the turnover. Traders in George Town and retailers around T. Nagar usually register when they cross the ₹40 lakh limit, or earlier, when wholesale buyers start insisting on GST invoices.
On the state side, GST in Tamil Nadu is run by the Commercial Taxes Department, and the application asks for your correct state jurisdiction. We map your Chennai address to the right circle before filing, so the file is not flagged. And if you sell online and stock inventory in other states, our virtual place of business (VPOB) service adds those state registrations while Chennai remains your anchor.
