New GST registrations for proprietors, firms, LLPs and companies — eligibility check, documents, Aadhaar or biometric verification and follow-up until the officer decides the application.
When GST registration is required
- Supplying only goods with aggregate turnover above ₹40 lakh a year (Maharashtra applies the ₹40 lakh limit, subject to exceptions such as ice cream, pan masala and tobacco).
- Supplying services, or goods and services, with aggregate turnover above ₹20 lakh a year (₹10 lakh in some special category states).
- Regardless of turnover: inter-state supplies of goods, casual and non-resident taxable persons, tax payable under reverse charge, e-commerce operators, persons supplying goods through them (subject to the exception below), input service distributors (ISDs), and persons required to deduct TDS or collect TCS under GST.
- Small sellers of goods on e-commerce platforms can stay unregistered below the threshold if they supply within one state only, hold a PAN and obtain an enrolment number.
Voluntary registration is also possible and can help B2B businesses pass on input tax credit.
Documents usually needed
- PAN of the business
- Aadhaar of the proprietor, partners or directors
- Photographs
- Proof of the principal place of business — electricity bill, rent agreement or owner's consent
- Bank account details
- Constitution document — partnership deed, LLP agreement or certificate of incorporation
The process in Maharashtra
- 1
Application
Form GST REG-01 is filed on the GST portal with the business, promoter and premises details.
- 2
Aadhaar verification
Since 8 February 2025, applicants in Maharashtra receive either an Aadhaar OTP link or a link to book a biometric verification appointment at a GST Suvidha Kendra, depending on risk parameters.
- 3
Officer review
The officer decides within 7 working days, or raises a query in REG-03 (a notice asking for clarification); where physical verification is needed, the period can extend to 30 days.
- 4
Certificate
Once approved, the registration certificate (REG-06) and GSTIN are issued on the portal.
Simplified registration from 1 November 2025. Applicants whose monthly output tax on supplies to registered persons is up to ₹2.5 lakh can opt for registration within 3 working days after Aadhaar authentication (Rule 14A), and system-identified low-risk applicants also get registration within 3 working days.
After registration
- Returns start immediately — GSTR-1 and GSTR-3B, monthly or quarterly, or CMP-08 and GSTR-4 if you opt for composition. See GST return filing.
- Display the GSTIN at your premises and on invoices.
- Amendments (address, partners, bank) are filed in REG-14.
- Cancellation is applied for in REG-16; if the department cancels a registration, revocation can be sought in REG-21 within 90 days, which an authorised officer can extend by up to 180 more days.
Frequently asked questions
Is GST registration free?
There is no government fee for GST registration. Our fee covers preparing the application and documents and following it up until the application is decided.
Do I have to visit a GST Suvidha Kendra?
Only if the portal asks for biometric verification. In Maharashtra the system decides, based on risk parameters, whether you can verify by Aadhaar OTP or must book an appointment at a GST Suvidha Kendra with your original Aadhaar, PAN and documents.
How long does registration take?
Usually up to 7 working days after a complete application and Aadhaar authentication, or up to 30 days where physical verification is required. Applicants eligible for the simplified scheme can be registered within 3 working days.
Can I register from home?
Yes, if the home is your place of business. You need proof of the premises — for example an electricity bill and the owner's consent, or a rent agreement.
