The Puducherry boutique-branding studio founder and the UT–Tamil Nadu GST cross-jurisdiction trap

Blanc Atelier was registered as a sole proprietorship under the GST Act in 2019, the same year Kavitha left her design job in Mumbai and moved back to Pondicherry. The registration address is her studio in White Town — Puducherry UT, GSTIN: 34XXXXPXXXXXX (Puducherry taxpayer). Revenue streams are split. About thirty percent comes from local or intra-UT work — tourism bodies, heritage hotels in town, regional clients whose travel time to Pondicherry justifies in-person collaboration. The remaining seventy percent, and the faster-growing segment, comes from clients based in Tamil Nadu: Chennai, Coimbatore, Madurai, Tiruppur, places she can reach by car in two to four hours, where the client brief happens by video call, and where the physical office presence required for traditional design studios has become optional. She invoices all her Tamil Nadu clients as IGST — Integrated GST — because under the GST law, when a service provider in one state (or UT) supplies services to a client in another state, the tax rate is 18% IGST instead of the standard 9% CGST + 9% SGST split. Her Puducherry clients are invoiced as CGST+UTGST, the split applicable to intra-state supplies. By February 2026, Kavitha had invoiced Tamil Nadu clients for approximately ₹18 lakh over the preceding six months. She had also spent approximately ₹14 lakh on office rent, utilities, equipment, internet, and design software, all of which triggered CGST+UTGST input credit when the invoices were registered on her GSTN portal.

The block on her input credit came as a notice from the Puducherry GST office in late February.

🗓️ The inter-state supply rule

Under the GST law, the concept of "place of supply" determines which tax rate applies. For services, the rule is found in Section 12 of the IGST Act, 2017: the place of supply is the location of the recipient of the service, not the location of the service provider's office. So when Kavitha, sitting in her studio in Puducherry, provides branding design services to a client in Chennai, the supply is "inter-state" and GST is collected at 18% IGST. The CGST and UTGST inputs incurred at her Puducherry office — rent paid to the landlord in Pondicherry, electricity billed to her Puducherry address — are normally eligible for input-tax credit, or ITC. The mechanism is that the 18% IGST she collects and pays to government is net of the eligible CGST+UTGST inputs she has incurred in producing that output.

This rule, on its face, is straightforward. The complexity emerges in registration and tracking. The GST law does not allow a single taxpayer to split registrations by place of supply. Kavitha has one GSTIN, one registration address (Puducherry), and one tax ID. All her supplies — both intra-UT and inter-state — are reported on the same monthly GSTR-1 filing. The inputs she incurs — all from Puducherry vendors — are reported on the same monthly GSTR-2A (the GST portal's record of her inward supplies). The ITC she claims is the net of these two.

On the surface, the arithmetic was correct. Kavitha had invoiced approximately ₹18 lakh in services to Tamil Nadu clients over six months (IGST at 18%, so approximately ₹3.24 lakh in IGST collected). She had incurred approximately ₹14 lakh in office expenses in Puducherry (with CGST+UTGST at 9% each, so approximately ₹1.26 lakh in combined CGST+UTGST incurred). The net ITC she claimed was the ₹1.26 lakh in CGST+UTGST incurred, deducted against the ₹3.24 lakh in IGST output.

But the GST officer who reviewed her filings saw something different in the numbers.

🏢

Puducherry Office (Input location)

CGST+UTGST @9% each

Kavitha's studio, rent, utilities, software subscriptions, design equipment — all registered and billed to her Puducherry address. Total annual input: ₹14 lakh over six months.

🗺️

Tamil Nadu Clients (Output location)

IGST @18%

Seventy percent of her revenue comes from Chennai, Coimbatore, Madurai. Each supply is inter-state, invoiced as IGST at 18%. Total annual output: ₹18 lakh over six months.

⚖️

ITC Mismatch

₹98,000 blocked

Officer flagged the mismatch: why claim CGST+UTGST inputs for services supplied as IGST output? The reasoning: inputs incurred in one state should match the tax regime of the output.

The GST officer's position, expressed in the formal language of a Section 74 notice under the CGST Act, was that Kavitha had claimed CGST+UTGST inputs that were incurred in Puducherry to offset IGST outputs that were supplied to Tamil Nadu. In the officer's interpretation, this was improper. The reasoning: if the output is inter-state and taxed as IGST, then the inputs should also be inter-state or IGST-taxable. If the inputs are intra-UT, then they should only offset intra-UT outputs. The officer disallowed ₹98,000 of the ₹1.26 lakh ITC she had claimed, and demanded the remainder be reversed.

The notice gave fifteen days to respond.

⚠️ The near-miss: the small studio with one registration

Kavitha's first reaction, when Ravi brought her the notice on a Thursday afternoon in February, was to call her accountant — a man named Ramanathan who worked remotely from Bangalore and had been handling her filings since she registered for GST in 2019. Ramanathan's response was measured but firm: the officer's position was aggressive but not unreasonable, and pushing back would require either expensive legal counsel or a very specific technical response that Ramanathan was not confident enough to draft. He suggested she could either accept the disallowance and pay the demand, or she could approach the Appellate Authority for Advance Rulings (AAR) to get a formal ruling on the question. The AAR process, he noted, would take four to six months and cost her approximately ₹25,000 in filing and legal fees. The demand, in the meantime, would be due within thirty days of the notice.

The ₹98,000 was not, in absolute terms, a catastrophic sum for a studio doing approximately ₹3 lakh in monthly revenue. But it was the margin that Blanc Atelier had carved out after paying salaries and rent. Paying it would mean depleting the studio's modest cash reserve and deferring a planned equipment upgrade she had been planning. Accepting the disallowance also felt wrong in a deeper sense — Kavitha knew, intuitively, that the rule about place of supply was not supposed to work the way the officer had interpreted it.

The second reaction was to search the GST portal itself for guidance. The GSTN portal's "Rules and Notifications" section had a search function. Kavitha searched for "inter-state supply input tax credit" and found three layers of documentation: the primary law (Section 12 of the IGST Act, 2017), the CBIC circulars (official guidance from the Central Board of Indirect Taxes and Customs), and taxpayer forums where other small businesses had described similar situations. By reading through these, she found a 2021 CBIC circular that addressed a scenario close to hers: when a service provider in a UT supplies inter-state services to clients in another state, the provider's office inputs, incurred in the UT, are eligible for ITC because the "place of supply" rule applies to the output, not to the location where inputs are incurred. The circular said, in official language: "Input tax credit is allowable on inputs used in the supply of inter-state services, irrespective of whether the input is incurred in the same state or a different state."

She copied this circular and sent it to Ramanathan. He confirmed it was the correct guidance and agreed it contradicted the officer's position. But he cautioned: the officer had already taken a position; winning on the merits would require her to formally appeal, and appeals in GST disputes often took a year or more to resolve. She would have to pay the demand first, then file a refund claim after the appeal was successful. In the interim, her cash would be locked up.

What nearly happened was the scenario that plays out for many small studios in border zones: Kavitha would have paid the ₹98,000, absorbed the impact, and moved on, technically correct but practically defeated. The question would have remained unresolved on the portal, the officer's position would have remained unchallenged, and the next time she invoiced a Tamil Nadu client, she would have been uncertain whether to claim ITC or not. The business would have adapted to the uncertainty by either under-claiming (and paying more tax than owed) or by structuring future supplies differently (perhaps by asking Tamil Nadu clients to travel to Puducherry for in-person collaboration, to change the place of supply back to intra-UT).

Instead, on the same evening, Arun — the senior designer in her team — asked if she had tried using a GST-compliance agent. His sister, he mentioned, had used one for her trading business in Hyderabad, and it had flagged a credit-note issue that she would have missed. Kavitha had not. She and Ravi set up a small tablet with a free compliance agent that evening and fed it the Section 74 notice and the CBIC circular she had found.

🌗 What changed

The agent read the notice in Tamil and English. It summarised the officer's position in plain language: "Officer claims that CGST+UTGST inputs incurred in Puducherry cannot offset IGST outputs to Tamil Nadu. Reasoning: mismatch of input and output locations." Then it cross-referenced the CBIC 2021 circular and highlighted the exact sentence: "Input tax credit is allowable on inputs used in the supply of inter-state services, irrespective of whether the input is incurred in the same state or a different state." It then drafted a response, in Tamil and English, structured as a formal reply to the Section 74 notice.

"தமிழ்நாடு வாங்குநருக்கு வழங்கிய சேவை இடைவரை சேவை என்பதால், புதுச்சேரி அலுவலகத்தில் செலவழிக்கப்பட்ட CGST+UTGST வரிக்களிசை (Input Tax Credit) பெறுவதற்கு தகுதி உண்டு. 2021 CBIC வட்டரே இந்த நிலையை தெளிவாக கூறிவிட்டுள்ளது."

(Because the service supplied to the Tamil Nadu buyer is inter-state in nature, the CGST+UTGST incurred at the Puducherry office is eligible for Input Tax Credit. The 2021 CBIC circular has explicitly stated this position.)

The agent also identified a secondary point: Kavitha's registration, while in Puducherry, was not restricted to intra-UT supplies. Under the GST law, a single GSTIN can cover multiple places of supply (intra-state, inter-state, international). The officer's position seemed to assume that a Puducherry-based registration could only claim inputs for Puducherry-based outputs — but this was not how the law worked for service providers. The agent drafted language citing Section 17 of the CGST Act, which allows input credit on inputs used in any taxable supply, regardless of where the supply is made.

Kavitha spent two days refining this response with Ravi and Ramanathan. On the third day, she filed the reply to the GST portal, attaching the CBIC circular as supporting evidence. She also filed a formal objection in the "Advance Notice" section of the portal, requesting that the GST office reconsider the position.

The response went through the portal on a Monday morning in early March. By mid-March, the GST office sent an acknowledgement. By April, the office issued a revised notice withdrawing the demand and allowing the full ₹98,000 ITC. The note cited the same CBIC 2021 circular that the agent had identified.

"என் அலுவலகம் வடக்கே இருக்கும்போது, வேலை தெற்கே இருக்குமேயில், நான் தெற்கேயான வரி கட்டணம் கட்டவேண்டுமென்று நினைத்தேன்."

— I thought that because my office was in the north and the work was in the south, I should pay the tax rate of the south — but the law reads differently. Place of supply is about the client, not the office.

🧭 Why we built it

There are an estimated three to four thousand small design studios, branding agencies, and creative consultancies in India that work in multi-state or UT-state boundary zones — White Town in Puducherry sending work to Tamil Nadu; studios in Daman servicing Gujarat and Maharashtra; design collectives in NCR territory navigating Delhi, Haryana, and Uttar Pradesh jurisdictions. The owners of these studios are domain experts in design, typography, and brand strategy. They are not, and should not need to be, experts in GST jurisprudence. But the moment they cross a state boundary with a client, they enter a different tax regime where the distinction between place of supply (where the work is consumed), place of registration (where their office is), and place of input (where they buy coffee and pay rent) become not a theoretical question but a monthly cash-impact question.

The standard response is that they hire an accountant. A competent accountant, like Ramanathan, can file the forms correctly — this is not the problem. The problem is one of confidence and proactivity. When a GST notice arrives from an officer who takes a position that feels aggressive or non-standard, the accountant's natural response is to escalate to a lawyer or to recommend accepting the disallowance and appealing later. Both paths are expensive and slow. The third path — understanding the specific CBIC circular or rule that actually governs the situation, and responding with it in real time — is knowledge work that requires cross-referencing three layers of legislation (the Act, the Rules, the circulars) on a tight deadline, under stress. Small studios do not have staff capacity for this. Accountants juggling fifty clients do not have the time to re-read circulars for each one.

What the agent did for Kavitha was what a very patient tax lawyer would do without charging: it read the notice, identified what the officer was claiming, searched the actual law for the rule that addressed the claim, found the CBIC guidance that directly answered it, and drafted a response. It worked because the law was clear once you knew where to look. The officer had taken a position based on a reading of "place of supply" that did not account for the inter-state guidance. The agent surfaced the guidance, and the officer reconsidered.

The same problem shows up for businesses near every state boundary in India. Sole proprietors in Himachal Pradesh supplying IT services to clients in Punjab. Design studios in Pondicherry serving Tamil Nadu. Writers in Goa working for clients in Karnataka and Maharashtra. They all face the same GST-jurisdiction uncertainty, and they all respond the same way: a good accountant, or a guess, or avoidance through structuring that shouldn't be necessary.

• 🗣️Cannot predict the officer's decision; only prepares the strongest case

🌱 What we hope happens

The most important thing that happened for Kavitha was not the ₹98,000 refund, though that was welcome. It was the clarity. She now understands, at a level of detail that she did not before, how place-of-supply rules work for inter-state services, and she has a concrete rule — the CBIC 2021 circular — that she can point to if another GST issue arises. Ramanathan now has that same document in his files. Arun, who suggested the agent, mentions it occasionally in casual conversation with other studio owners he knows. Ravi uses the response as a template for future GST objections.

What we hope happens is that a small creative business in a border zone — Pondicherry to Tamil Nadu, Daman to Gujarat, Delhi to Haryana — can do the work they do best, which is the work of design and strategy, without absorbing the cognitive load of cross-state tax compliance. We hope that when a notice arrives from a GST officer, the studio can read it, understand it, and respond to it in real time, with confidence, using the same networks (a tablet, a language, a quiet summary) that already exist in the studio's workflow. We hope that the distinction between place of supply, place of registration, and place of input becomes not a source of cash-drain anxiety but a straightforward question that has a clear answer, rooted in a CBIC circular that a small team can cite.

The studio is still four people. The revenue model is still seventy percent inter-state. The border between Puducherry and Tamil Nadu is still three hours by car. But the uncertainty — the very specific uncertainty about whether the tax regime that the law stated was actually the regime the officer would enforce — has been replaced by something quieter: a rule, a reference, and a studio that can sleep a little better knowing the answer.
