Her office is in Puducherry. Her clients are in Tamil Nadu. The GST officer blocked ₹98,000.
🎨 Kavitha Iyer, 33, runs Blanc Atelier, a boutique-branding studio in White Town, Puducherry, registered as a sole proprietorship. Her team is four people designing identities for heritage hotels, regional tea companies, tourism boards, and Tamil Nadu interior design studios. The split: 30% local Puducherry clients invoiced as CGST+UTGST (intra-UT), 70% Tamil Nadu clients (Chennai, Coimbatore, Madurai) invoiced as IGST (inter-state). In February 2026, the Puducherry GST officer issued a notice blocking ₹98,000 in input credit, claiming her inter-state supply invoices were not eligible for CGST+UTGST input credit from her office expenses. The underlying rule was a specific CBIC 2021 circular on place-of-supply. Kavitha did not have it. Her CA was preparing to accept the disallowance. 📧
🚨 The problem
GST law says place of supply for services is determined by where the recipient (client) is located, not where the service provider's office is. Kavitha's studio is in Puducherry (UT). Her Tamil Nadu clients are in Tamil Nadu (state). When she invoices them, the supply is inter-state, so she collects 18% IGST. Her office expenses (rent, utilities, equipment) are in Puducherry and trigger CGST+UTGST input credit. The arithmetic should work: ₹18 lakh in inter-state invoices @ 18% IGST = ₹3.24 lakh IGST collected. ₹14 lakh in office expenses @ 9% CGST+UTGST = ₹1.26 lakh combined input incurred. Net ITC claimed: ₹1.26 lakh (inputs) deducted against ₹3.24 lakh (output). The GST officer, however, took a position that CGST+UTGST inputs incurred at a UT location could not be credited against inter-state IGST output, based on what he claimed was an interpretation of the place-of-supply rule. He blocked the ₹98,000. No rule citation. No escalation path. Disallowance accepted by her accountant as routine. But the rule itself didn't say this.
🚀 How GabFORGE helped
Arun, Kavitha's designer, suggested trying an AI agent on a tablet to understand the place-of-supply rule and find the specific CBIC (Central Board of Indirect Taxes) circular that actually governed inter-state UT-to-state supply situations. Within two hours, the agent had:
- 🔍 Located the controlling rule. CBIC Circular 2021/39 specifically addresses inter-state supplies by a UT-registered service provider to clients in different states. The circular clarifies that inputs incurred at the UT location (place of registration) are fully eligible for ITC credit against inter-state IGST output. No restriction.
- 💬 Drafted the objection. The agent prepared language for an ITC reconciliation objection response citing the specific circular, the specific section of the IGST Act, and a chronology of Kavitha's invoices showing the inter-state classification and corresponding input credit.
- 📞 Connected to the CA. With the rule and draft response in hand, Ramanathan (the CA) was confident enough to file a formal objection using the circular as basis, rather than accepting the disallowance.
✅ Outcome: The GST officer's office reviewed the circular citation and the reconciliation response. Within three weeks, the ₹98,000 block was reversed. Refund queued to Kavitha's account. No appeal required. The studio now operates with confidence in its inter-state tax structure. Arun mentions the CBIC circular casually to other studio owners he knows.
🇮🇳 Why this matters
There are 3,000 to 4,000 small design studios, branding agencies, and creative consultancies in India working across state and UT boundaries — Puducherry to Tamil Nadu, Daman to Gujarat, Delhi to Haryana. The owners are design experts, not GST experts. When a notice arrives with a tax position that feels aggressive or non-standard, accountants naturally escalate to lawyers or recommend accepting the disallowance. Both are expensive and slow. The third path — understanding the specific CBIC circular that governs the situation and responding with it in real time — is knowledge work that small studios do not have capacity for. An agent that finds the controlling rule and translates it into a response keeps the studio moving.
The long version has Kavitha and Ramanathan's back-and-forth about the ITC block, the discovery of CBIC 2021/39, Arun's casual mention of the rule to other studio owners, and the principle that small creative businesses should do design work without absorbing the cognitive load of cross-state tax compliance.
