01What documents are required for GST registration?
Required documents include PAN card of the business/proprietor, Aadhaar card, proof of business address (electricity bill/rent agreement), bank account details (cancelled cheque or bank statement), photographs, and for companies — Certificate of Incorporation and MOA/AOA.
02How long does GST registration take?
If all documents are in order and Aadhaar authentication is completed, GST registration is granted within 3 working days. If the application is selected for verification or documents need clarification, it can take up to 7 working days. The applicant receives the GSTIN by email and SMS.
03What is the GST registration fee?
GST registration is free of charge on the GST portal (www.gst.gov.in). There are no government fees. If you use a CA or tax consultant for assisted registration, professional fees typically range from Rs 1,000 to Rs 3,000.
04Can a person have multiple GST registrations?
Yes. A business operating in multiple states must register separately in each state. Within a state, a business can obtain multiple registrations for different business verticals. Each registration has a separate GSTIN (15-digit number) and separate compliance obligations.
05What is the penalty for not registering for GST when required?
Operating without mandatory GST registration is an offence under Section 122 of the CGST Act. The penalty is 100% of the tax evaded or Rs 10,000, whichever is higher. Officers can also seize goods and vehicles in transit without proper documentation.
