GST Registration for Consultants & Professional Service Providers
Consultants across management, IT, HR, legal, and financial advisory need GST registration once annual turnover crosses ₹20 lakh (₹10 lakh in special-category states). Corporate clients typically insist on a GSTIN before releasing payment against your invoice, since they need it to claim their own input tax credit.
B2B invoicing
Corporate clients almost always need your GSTIN on the invoice to claim ITC — unregistered consultants can lose out on larger contracts for this reason.
Reverse charge awareness
Certain services (like those from an unregistered supplier to a registered business, or specific notified services) fall under reverse charge, where the recipient pays GST directly.
Multi-client, multi-state work
Consultants serving clients across states should register correctly to charge IGST where applicable, rather than CGST/SGST.
Frequently Asked Questions
Professional service providers like consultants, architects, and company secretaries need GST registration once turnover crosses ₹20 lakh (₹10 lakh in special-category states). Healthcare services by doctors and clinics are largely exempt from GST, but registration may still be required if the practice sells taxable products (e.g., a pharmacy) or provides other taxable services alongside.
Any business supplying goods with annual turnover above ₹40 lakh (₹20 lakh in special-category states), or supplying services with turnover above ₹20 lakh (₹10 lakh in special-category states), must register for GST. Registration is also mandatory regardless of turnover for inter-state suppliers, e-commerce sellers, casual taxable persons, and those liable under reverse charge.
