Frequently Asked Questions

I'm a freelance developer earning ₹15 lakh — should I register for GST voluntarily? If your clients are companies: Yes — register voluntarily. They can claim ITC on GST you charge (18%). You can claim ITC on your business expenses (laptop, software). Net tax impact is minimal, and you appear more professional.

GST registration for home-based business — can I use home address? Yes — residential address can be used as principal place of business for freelancers/home-based businesses. Upload: Electricity bill (self-owned) or Rent agreement + NOC (rented). This is very common.

How long does GSTIN registration take? With Aadhaar OTP authentication: Typically 3 working days, often same day. Without Aadhaar: 7–30 days. Ensure all documents are clear and business address proof is current.

If I register for GST, must I collect 18% GST from all clients? From Indian clients (B2B): Charge 18% GST, which they can claim as ITC. From foreign clients (exports): Zero-rated, no GST charged but you're registered and can claim ITC on your purchases. GST registration is separate from GST charging.

What happens if I cross ₹20 lakh but don't register for GST? GST evasion penalties: Tax due + 100% penalty (for intentional evasion). For bona fide non-registration: Retroactive registration required with all pending taxes + interest. Register proactively the moment you approach the threshold.
