GST Registration in Chennai
Register for GST correctly the first time — document preparation, ARN tracking, and follow-up with the department, handled end-to-end.
Who needs to register for GST?
GST registration is mandatory once your aggregate turnover crosses ₹40 lakh for goods (₹20 lakh in special-category states) or ₹20 lakh for services, or if you sell across state lines, sell on e-commerce marketplaces, or are otherwise required under the CGST Act regardless of turnover (e.g. casual taxable persons, e-commerce operators). Registering late attracts penalties and blocks Input Tax Credit for the pre-registration period, so getting the timing and documentation right at the outset matters. For current rules and procedures, see the GST Portal (gst.gov.in).

FAQ
Frequently asked questions
What is the turnover limit for mandatory GST registration?
₹40 lakh for suppliers of goods (₹20 lakh in special-category states) and ₹20 lakh for suppliers of services. Certain categories — inter-state suppliers, e-commerce sellers, casual taxable persons — must register regardless of turnover.
How long does GST registration take?
Typically 3–7 working days from application if documents are in order and there's no departmental query; it can extend to 15–20 days if a physical verification or additional clarification is required.
What documents are required for GST registration?
PAN, Aadhaar, photograph, proof of business constitution (partnership deed/incorporation certificate), address proof for the principal place of business, and bank account details. Additional documents apply for companies and LLPs.
Can I register for GST voluntarily even if I'm below the threshold?
Yes. Voluntary registration lets you claim Input Tax Credit and is often required by marketplaces (Amazon, Flipkart) and larger B2B customers who prefer to deal only with GST-registered vendors.
What if I need to fix a GST notice or dispute after registration?
Routine post-registration notices and amendments are handled here. For show-cause notices, appeals, or GST Appellate Tribunal matters, see our dedicated GST litigation service.
