Dealintax answers the most common questions about GST registration in India — structured for quick reference and expert clarity.

What is GST registration and who needs it?

GST (Goods and Services Tax) registration is a mandatory process for any business in India whose aggregate annual turnover exceeds ₹20 lakh (₹10 lakh for special category states). Businesses involved in inter-state supply, e-commerce, or acting as agents must register regardless of turnover. Registration gives your business a 15-digit GSTIN and the legal right to collect GST, claim input tax credit, and file GST returns.

How long does GST registration take in India?

The government’s processing time for GST registration is 7–10 working days from the date of complete document submission. With Dealintax’s CA-assisted service, your application is prepared and submitted within 24 hours. Most clients receive their GSTIN within 3–5 working days of submission, provided all documents are in order and no queries are raised by the GST officer.

What documents are required for GST registration?

The core documents required for GST registration are: (1) PAN card of the business or proprietor, (2) Aadhaar card of the authorised signatory, (3) proof of business address — electricity bill, rent agreement, or NOC from property owner, (4) bank account statement or cancelled cheque, and (5) entity-specific documents such as the Certificate of Incorporation for companies or Partnership Deed for firms.

What is the cost of GST registration through Dealintax?

Dealintax charges ₹999 for standard GST registration, which includes expert CA review of all documents, error-free application preparation, submission to the GST portal, and follow-up until your GSTIN is issued. The government fee for GST registration is zero. The ₹999 covers professional service, time savings, and accuracy guarantee.

Can I do GST registration myself without a CA?

Yes, you can apply on the GST portal (gst.gov.in) yourself. However, errors in document upload, incorrect business category selection, or mismatched information frequently cause rejections or officer queries, delaying registration by 2–4 weeks. Dealintax’s CA-assisted service eliminates this risk and is priced at ₹999, making professional help the more practical choice for most business owners.

Is GST registration compulsory for a new business?

GST registration is compulsory for new businesses if: (a) annual turnover is expected to exceed ₹20 lakh, (b) the business makes inter-state supplies, (c) the business sells through an e-commerce platform, or (d) the business provides services subject to reverse charge. Voluntary registration is also available and beneficial for claiming input tax credit.
