Why GST applications from Tamil Nadu get stuck, and how we prevent it
- AddressAddress proof doesn't matchThe door number, ward or PIN on the electricity bill or property papers differs from the application. We match them before filing.
- Land papersProperty in someone else's nameIf the building or land is still in a parent's or grandparent's name, add the owner's consent letter and ID. We check the patta, chitta or tax receipt before uploading.
- AadhaarAadhaar authentication skippedWithout it, the officer can order a site visit and approval can take up to 30 days. We complete it on day one.
- PhotosUnclear photos of the premisesOfficers often ask for a photo showing the name board and the building. We tell you exactly what to click.
- LimitUsing the goods limit for servicesThe ₹40 lakh limit is only for businesses selling goods. If you also supply services, the limit is ₹20 lakh, and late registration means tax, interest and penalty on past sales.
- CodesWrong HSN/SAC or business typeChoosing the wrong codes or constitution leads to queries later. We select them based on what you actually sell.
- QueriesMissing the 7-day reply windowAn unanswered query (REG-03) leads to rejection. We reply within the deadline, with no extra fee.

Can I register GST from my home in Tamil Nadu?+
Yes. Your house can be the principal place of business, with an electricity bill or property tax receipt, and a consent letter if the house is in a family member's name. Keep a small name board for any verification.
Can a small business in Tamil Nadu choose the composition scheme?+
Yes. Traders and manufacturers in Tamil Nadu with turnover up to ₹1.5 crore can opt for composition and pay 1% of turnover (5% for restaurants), and service providers up to ₹50 lakh pay 6%. You can't collect GST from customers or claim input tax credit, and goods can't be sold to other States.
Is there profession tax in Tamil Nadu?+
Yes. In Tamil Nadu, profession tax is collected half-yearly by the local body: the corporation, municipality or town or village panchayat where you work or run your business. Employers deduct it from salaries, and businesses and professionals pay it directly. It is separate from GST; we can help with both.

No. One GST registration covers the whole State. A shop, godown or office in another district of Tamil Nadu is added as an additional place of business. You need a separate registration only for another State.
I have an office in Tamil Nadu and another in Bengaluru or Puducherry. Is one GST registration enough?+
No. GST registration is State-wise. Your Tamil Nadu premises are registered in Tamil Nadu (GSTIN starting 33); a Bengaluru office needs its own Karnataka registration (starting 29) and a Puducherry office another (starting 34), under the same PAN.
When are GST returns due for a business in Tamil Nadu?+

GST doesn't need one, but corporations, municipalities and town panchayats issue trade licences for shops in their towns, and shops and offices register under the Tamil Nadu Shops and Establishments Act, 1947. A trade licence is also useful supporting proof of your place of business.
Do factories, textile units and IT firms in Tamil Nadu need GST registration from the start?+
Usually yes. Units in SIPCOT and SIDCO estates, auto and engineering suppliers, textile and leather exporters and IT firms selling to companies supply other businesses, so they need a GSTIN to give tax invoices, claim input tax credit and move goods with e-way bills.
