How to register a business in Tamil Nadu.

Registering a business in Tamil Nadu means dealing with two layers: central registrations that are the same across India, and Tamil Nadu state registrations that are specific to where you operate. Here is exactly what you file and where, with the official portals.

Company & LLP (central)

A Private Limited company or LLP in Tamil Nadu is registered centrally with the Ministry of Corporate Affairs, the same process nationwide. Use SPICe+ for a company or FiLLiP for an LLP; PAN, TAN and often EPFO and ESIC are bundled in.

Tamil Nadu business single window

Partnership firms, proprietorship registrations, trade licences and state incentives in Tamil Nadu go through the state single-window or industries portal.

Shops & Establishment

Almost any commercial workplace in Tamil Nadu, including a small office or a two-person startup, needs this state labour registration, usually within 30 days of starting.

Professional tax: Levied in Tamil Nadu

Levied by local bodies (half-yearly) rather than a single state slab. Register with your municipality or corporation.

A typical order of registration in Tamil Nadu

  1. Decide your structure. Private Limited or LLP if you will raise funding or want limited liability; proprietorship or partnership for the simplest start.
  2. Register the entity. Company or LLP centrally on the MCA portal; partnership with the Tamil Nadu Registrar of Firms; a proprietorship is built from the registrations below.
  3. Get PAN, TAN and GST as needed. PAN and TAN come with incorporation; register for GST if you cross the threshold or sell online or across states.
  4. Take the state registrations. Shops & Establishment for your Tamil Nadu premises, and professional tax since Tamil Nadu levies it, plus a trade licence if your activity needs one.
  5. Add free recognitions. Udyam (MSME) and DPIIT startup recognition are free and worth taking, and open schemes and tenders.
