GST Consultancy clarity on every GST question your business faces.
Expert GST consultancy services in Mumbai and across India — HSN/SAC classification, place of supply determination, reverse charge mechanism advisory, input tax credit optimisation, GST impact analysis for new businesses, transaction-level GST structuring, and written GST opinions by ICAI-registered Chartered Accountants.
GST is one of the most dynamic and complex tax statutes in India, amended frequently through notifications, circulars, and Finance Act changes. Businesses encounter GST questions at every stage — during product launch (correct tax rate and HSN code), business expansion (place of supply and multi-state registration), procurement (ITC eligibility and blocked credits), and transactions with overseas parties (export, import, and OIDAR services). Getting these wrong does not just attract penalties — it can affect cash flow, pricing, and customer relationships.
The most consequential GST advisory areas include HSN/SAC classification, where an incorrect code means a wrong tax rate that the customer cannot claim as ITC at the right rate; place of supply, which determines whether the transaction is intra-state (CGST + SGST) or inter-state (IGST) and who gets the tax revenue; and reverse charge mechanism, where the recipient is liable to pay GST on behalf of the supplier for specified categories of goods and services. Errors in these areas generate notices, demands, and interest.
Our GST consultancy practice covers written GST opinions, HSN/SAC code classification advisory, place of supply analysis for complex transactions (secondment, digital services, intermediary services, construction), ITC eligibility review, reverse charge mechanism identification and compliance, GST structuring for new businesses, impact analysis of GST amendments on existing pricing and contracts, and representation before the Authority for Advance Ruling (AAR) for binding tax rulings.

Frequently Asked Questions
GST consultancy covers advisory, opinion, and strategic guidance on GST compliance, classification, transaction structuring, and dispute avoidance. It goes beyond return filing to address the specific GST implications of your business activities.
Under the reverse charge mechanism (RCM), the recipient of goods or services is liable to pay GST instead of the supplier. RCM applies to notified categories including legal services, GTA, director remuneration, and imports. The recipient must self-invoice and pay GST directly.
Place of supply determines whether a transaction is intra-state (attracting CGST + SGST) or inter-state (attracting IGST). An incorrect determination leads to paying the wrong tax, which cannot be adjusted and creates a demand for the correct tax plus interest.
ITC optimisation involves identifying all eligible input tax credit on purchases, capital goods, and services; ensuring timely supplier filing so credits appear in GSTR-2B; avoiding blocked credits under Section 17(5); and structuring procurement contracts to maximise ITC flow.
An Advance Ruling is a binding written decision from the Authority for Advance Ruling (AAR) on a specific tax question raised by a taxpayer before entering into a transaction. It provides legal certainty and can be relied upon in assessments.
