Frequently Asked Questions
What is the GST registration threshold for a business in India?
In India, the GST registration threshold is ₹20 lakh for service providers and ₹40 lakh for businesses supplying goods. Businesses whose annual turnover exceeds these limits must register. Some categories — such as e-commerce sellers, inter-state suppliers, and reverse charge recipients — must register regardless of turnover.
Is physical verification of premises required for GST registration in India?
Physical verification is not always mandatory but the GST officer may initiate it at their discretion, especially for new registrations in India. If a physical visit is ordered, it must be completed within 30 days of filing. BigMind Consulting coordinates with clients to prepare the premises documentation and respond to any verification notices promptly.
How long does GST registration take in India?
GST registration is typically processed within 7 working days if all documents are correctly submitted and no physical verification is initiated. If verification is ordered, the total timeline may extend to 30 days.
Can I voluntarily register for GST below the threshold limit?
Yes. Voluntary GST registration is permitted even if your turnover is below the mandatory threshold. Many small businesses in India register voluntarily to claim input tax credit (ITC) on purchases and to improve credibility with larger customers and B2B buyers.
What is the HSN code and when is it mandatory?
HSN (Harmonised System of Nomenclature) codes classify goods and services for GST purposes. Businesses with turnover above ₹5 crore must use 6-digit HSN codes on invoices; those between ₹1.5 crore and ₹5 crore use 4-digit codes. Businesses below ₹1.5 crore are exempt from HSN on invoices but must still select HSN in the GST registration portal.
