GST ITC on Showroom & Office Interior Works (Section 17(5)(d)): Complete Statutory Compliance Guide for CAs & CFOs

Statutory Context: The ₹Crore Corporate Battleground Over Section 17(5)(d)

For Indian corporate finance teams, retail store chains, bank branches, co-working operators, and IT enterprises, capital expenditure incurred on office interiors, showroom furnishing, and commercial fitouts represents one of the largest sources of disputed Input Tax Credit (ITC). Jurisdictional GST authorities across states routinely issue Show Cause Notices (SCNs) under Section 73, Section 74, or Section 74A of the Central Goods and Services Tax (CGST) Act, 2017, demanding 100% reversal of ITC availed on joinery, carpentry, electrical installation, false ceilings, and interior designing.

The departmental disallowance hinges on a mechanical, overly broad interpretation of Section 17(5)(d), which bars ITC on goods or services received by a taxable person for the "construction of an immovable property (other than plant or machinery) on his own account." Field formations routinely treat every commercial showroom setup, retail fitout, and office renovation as "construction of immovable property," ignoring whether the assets are detachable, whether the premises are leased, and how the expenditure is accounted for in audited financial statements.

In a landmark judgment pronounced in October 2026, the Goods and Services Tax Appellate Tribunal (GSTAT), Thiruvananthapuram Bench, in the case of Oxygen The Digital Shop Vs Commissioner of Kerala State GST (2026 taxguru.in 17026), decisively struck down the departmental demand. The Tribunal established two foundational statutory doctrines: first, detachable commercial furnishing and display fixtures installed in leased premises do not constitute immovable property; and second, under Explanation 1 to Section 17(5)(c) and (d), statutory blockage applies only "to the extent of capitalisation to the said immovable property." Where the GST component is not capitalized into fixed assets and no depreciation is claimed under the Income-tax Act, 1961, Input Tax Credit is fully admissible under Section 16(1).

The Anatomy of the Dispute: Oxygen The Digital Shop Case

The appellant, a registered partnership firm (GSTIN: 32AABFO4106G1ZV) engaged in multi-brand retail trading of digital gadgets, electronics, and post-sale maintenance services, took commercial premises on lease across Kerala (including Vellayambalam and Nedumangadu) to operate retail digital showrooms. To store and display inventory, the firm procured interior furnishing, carpentry, and joinery works under four tax invoices totaling ₹11,22,940 in GST (CGST of ₹5,61,470 and SGST of ₹5,61,470) from a specialized contractor, Brightech Interiors and Exteriors Private Limited.

The contractor billed the services under SAC Code 995476 (Joinery and carpentry services) and SAC Code 995473 (Painting services). During post-audit scrutiny, the Deputy Commissioner of State Tax denied the entire ITC of ₹11,22,940 and initiated demand proceedings, confirmed by the First Appellate Authority (Joint Commissioner of Appeals). The Revenue raised three distinct objections:

1. The Immovable Property Theory: The Revenue argued that showroom interiors, wooden paneling, and fixed joinery are permanently embedded into the walls and floors, cannot be dismantled without damage, and therefore constitute "additions or alterations to immovable property" blocked under Section 17(5)(d).
2. The Classification Challenge: The department argued that the contractor billed under building completion codes (SAC 995476 / 995473) rather than interior design advisory (SAC 998391), proving the civil construction nature of the supply.
3. Statutory Override: The department contended that meeting the general conditions of Section 16(2) cannot override the specific non-obstante clause of Section 17(5), placing the entire burden of proof on the taxpayer under Section 155.

Tri-Partite Statutory Framework: Sections 16(1), 17(5)(d), and 16(3)

To defend against Section 17(5)(d) disallowances, tax advisors and CFOs must harmonize three interconnected provisions of the CGST Act alongside the Income-tax Act, 1961:

1. Section 16(1) — Direct Nexus with Furtherance of Business

Under Section 16(1), every registered person is entitled to claim credit of input tax charged on inward supplies of goods or services used or intended to be used in the course or furtherance of business. GSTAT observed that modern digital retail requires specialized wooden and glass display fixtures, secure shelving, and customer demo counters. Without these display installations, retail trading cannot function. Therefore, the inward supplies have an undeniable, direct nexus with taxable commercial operations.

2. Section 17(5)(d) & Explanation 1 — The Scope of "Immovable Property"

Section 17(5)(d) does not enact a blanket ban on all renovation or interior work. The legislature incorporated two critical statutory safeguards:

• Exception for Plant and Machinery: Plant and machinery is expressly excluded from the immovable property restriction.
• Capitalization Test in Explanation 1: Renovation, additions, alterations, or repairs are deemed to be "construction" only to the extent they are capitalised to the said immovable property. If an expenditure is either expensed as revenue repairs under Section 30/37 of the Income-tax Act or capitalized under a movable asset block (Furniture and Fixtures), it does not constitute capitalization to "the said immovable property."

3. Section 16(3) — Anti-Double Dipping Mechanism

Section 16(3) of the CGST Act provides: "Where the registered person has claimed depreciation on the tax component of the cost of capital goods and plant and machinery under the provisions of the Income-tax Act, 1961, the input tax credit on the said tax component shall not be allowed."

This provision creates an explicit statutory choice: the taxpayer can either claim Income Tax depreciation under Section 32 on the GST paid by adding it to asset cost, OR separate the GST into the electronic credit ledger to take ITC under GST law. Claiming both is prohibited. Conversely, when the taxpayer deliberately excludes the GST component from asset cost and claims zero depreciation under income tax, the tax component is never capitalized, effectively taking it outside the ambit of Section 17(5)(d).

4. Procedural Bar: Revenue Cannot Traverse Beyond the SCN (Section 75(7))

Addressing the Revenue's belated argument that the contractor billed under civil finishing codes (SAC 995476) instead of interior design (SAC 998391), GSTAT laid down a vital jurisdictional rule: The department cannot dispute the supplier's service classification at the recipient's assessment stage if the Show Cause Notice never challenged it.

Under Section 75(7) of the CGST Act, an adjudication order cannot confirm a tax demand on grounds different from those specified in the original notice. Since the supplier's SAC classification was accepted and taxed at 18% at the supplier end, the recipient cannot be penalized for how the vendor described the line item.

Comparative Analysis: Departmental Stand vs. GSTAT Mandate

The following structured matrix compares the traditional departmental disallowance framework against the binding legal principles affirmed by GSTAT Thiruvananthapuram:

Audit & Legal Parameter	Traditional Departmental Stand	GSTAT Landmark Ruling Principle	Statutory Citation & Evidence
Asset Characterization	Every fitout attached to civil walls/floors is deemed an immovable civil structure.	Detachable shelves, modular counters, and display units are movable commercial assets.	Section 16(1) CGST Act & WeWork India (Karnataka AAAR).
Capitalization Test	Treats gross invoice amount (including GST) as automatically capitalized to building.	Section 17(5)(d) applies only to the extent expenditure is capitalized to immovable property.	Explanation 1 to Section 17(5)(c) and (d) of CGST Act.
Tax Component Accounting	Ignores internal accounting treatment; disallows credit regardless of ledger entries.	Excluding GST from asset cost and claiming zero depreciation satisfies Section 16(3).	Section 16(3) CGST Act read with Section 32 Income-tax Act.
Tenancy & Premise Ownership	Applies Section 17(5)(d) indiscriminately to owned and leased/rented premises.	Tenant does not own the building; fitouts made for retail operations cannot merge into landlord's realty.	Registered lease agreements & landlord no-objection certificates.
Vendor SAC Code Dispute	Disallows credit if contractor used civil codes (e.g., SAC 995476 joinery).	Department cannot alter grounds or question supplier's SAC code if unmentioned in SCN.	Section 75(7) CGST Act & principles of natural justice.

The 4-Pillar Chartered Accountant Certificate Standard

A central feature of the GSTAT judgment is the Tribunal's reliance on a formal attestation issued by an independent Chartered Accountant firm (M/s Byju & Associates, Chartered Accountants). To satisfy the burden of proof under Section 155 of the CGST Act, every enterprise claiming ITC on high-value interior works must maintain a certified working paper verifying the following four evidentiary pillars:

When presenting audit working papers during statutory or tax audits under Section 44AB, tax professionals should evaluate tax audit applicability under Section 44AB to ensure that Clause 18 (Depreciation allowance) of Form 3CD precisely mirrors this accounting segregation and does not include GST in the WDV opening block.

Conclusion: The Strategic Roadmap for Corporate Tax Heads

The GSTAT Thiruvananthapuram ruling in Oxygen The Digital Shop delivers much-needed clarity on one of the most litigated sections of the GST law. By holding that detachable showroom furnishing in leased premises does not equate to the construction of immovable property, and confirming that the non-capitalization of the GST component takes the transaction outside Section 17(5)(d), the Tribunal has armed taxpayers with an unassailable legal defense.

However, securing this credit requires meticulous accounting discipline. Corporate finance teams cannot rely on legal arguments alone if their accounting ledgers fail to segregate the tax component or if the fixed asset register inadvertently groups commercial fitouts under immovable civil assets. By implementing strict accounting controls, securing an independent CA certificate, and conducting automated vendor reconciliations, enterprises can confidently claim legitimate Input Tax Credit on multi-crore fitout expenditures and successfully defend their positions against departmental scrutiny.
