GST Registration
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 usually want a GSTIN before they release 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 often lose larger contracts for this reason.
Reverse charge awareness
Some services fall under reverse charge, where the recipient pays GST directly, such as supplies from an unregistered vendor to a registered business, or specific notified services.
Multi-client, multi-state work
Consultants serving clients across states should register correctly so they charge IGST where it applies, 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.
