GST Registration Services

Obtaining your Goods and Services Tax Identification Number (GSTIN) correctly and on time, whether registration is mandatory or voluntary.

Quick answer

Businesses must register for Goods and Services Tax (GST) once aggregate turnover crosses ₹40 lakh for goods (₹20 lakh in special category states) or ₹20 lakh for services (₹10 lakh in special category states). Certain categories — including inter-state suppliers of goods, e-commerce operators, casual taxable persons, and those liable under reverse charge — must register regardless of turnover. Applications are filed online in Form GST REG-01, and a GSTIN is typically issued within seven working days of submitting complete documentation.

Why choose us

Why getting registration right matters

What sets our approach apart.

Wrong details are hard to unwind later

Errors in business constitution or principal place of business at registration require a formal amendment process to correct.

Some categories must register regardless of turnover

Inter-state suppliers of goods, e-commerce sellers and casual taxable persons must register even below the general threshold.

Voluntary registration can still make sense

Registering below the threshold allows you to claim Input Tax Credit (ITC) and often makes it easier to work with GST-registered clients.
