Mumbai ITAT Landmark Ruling: Multiple Flats on Different Floors Qualify as 'One Residential House' Under Section 54F

In a landmark judgment offering substantial relief to high-net-worth individual (HNI) taxpayers and real estate investors, the Mumbai Bench of the Income Tax Appellate Tribunal (ITAT) has held that purchasing two separate residential flats situated on different floors within the same building can collectively qualify as an investment in “one residential house” for the purpose of claiming exemption under Section 54F of the Income Tax Act, 1961.

This progressive ruling in the case of Sunil Indravadan Shah vs. Income Tax Officer (ITO) re-emphasizes the foundational judicial principle of substance over form. The tribunal determined that separate legal agreements, distinct floor placements, individual municipal tax assessments, and independent entrance doors do not negate the claim of a single combined residential unit, provided the functional utility and objective of the purchase reflect unified family living.

1. Background & Factual Matrix of the Case

The assessee, Mr. Sunil Indravadan Shah, engaged in significant capital asset transactions during the relevant assessment year. The background of the legal dispute unfolds through the following sequence of events:

• Capital Gain Generation: The taxpayer sold six commercial units, generating Long-Term Capital Gains (LTCG) totaling nearly ₹5 Crore.
• Reinvestment in Residential Property: To mitigate capital gains tax liability under Section 54F, the taxpayer reinvested the net sale consideration into purchasing two residential flats from the same developer within the same residential complex. The acquisition cost for each flat exceeded ₹2.5 Crore.
• Location & Architectural Layout: The two residential units were situated on different floors of the same multi-story building.

2. The Revenue’s Objections and Disallowance by the Assessing Officer (AO)

During the scrutiny assessment proceedings, the Assessing Officer (AO) disallowed the Section 54F exemption claim regarding the second flat. The Tax Department anchored its rejection on rigid technical arguments:

1. Separate Legal Documentation: The real estate developer executed two distinct sale deeds/agreements for the two flats, which attracted independent stamp duty assessments and registration processing.
2. Physical Separation & Entrances: The flats were located on different floors and possessed separate entrance doors, distinct utility meters (electricity/water), and separate municipal tax numbers.
3. Literal Interpretation of "One Residential House": The AO contended that Section 54F strictly mandates investment in a single residential house, and acquiring two distinct units on different floors constitutes buying two independent residential properties.

Consequently, the AO restricted the Section 54F exemption to only one flat and added the balance capital gains to the assessee's taxable income, levying a hefty tax demand.

3. Judicial Analysis and ITAT Mumbai’s Rationale

Aggrieved by the Assessing Officer's disallowance, the taxpayer appealed before the Income Tax Appellate Tribunal (ITAT), Mumbai Bench. The tribunal meticulously evaluated the statutory intent behind Section 54F, relevant judicial precedents, and the practical realities of urban housing in Indian metros.

A. Functional Utility Supersedes Legal Documentation

The Tribunal highlighted that in modern urban high-rise developments, buyers frequently purchase multiple adjacent or stacked units to accommodate large or growing joint families. The existence of separate allotment letters, sale deeds, or floor locations is primarily a matter of developer administrative convenience and architectural floor planning, not a reflection of independent usage.

B. The "Substance Over Form" Test

ITAT held that tax authorities must evaluate the functional connectivity and living patterns of the taxpayer rather than relying solely on separate entrance numbers or municipal registration entries. If the taxpayer acquired the flats to function as a singular, unified residential habitat for family cohabitation, the statutory condition of "one residential house" is fully satisfied.

4. Harmonizing Judicial Precedents: Section 54 vs. Section 54F

The ITAT Mumbai relied on settled principles established by various High Courts across India, including landmark judgments by the Karnataka High Court in CIT vs. K.G. Rukminiamma and the Delhi High Court in CIT vs. Ananda Verma, which affirmed that:

"The expression 'a residential house' used in Section 54/54F should not be restrictively construed as a single flat or single unit. Where two or more flats in the same building structure are purchased and used as a combined unit for the residence of the family, they constitute 'one residential house'."

Although the Income Tax Department regularly argues that units situated on different floors cannot physically be merged into one contiguous flat, the Mumbai ITAT firmly established that strict physical contiguity is not a mandatory legal prerequisite, provided the residential space serves a unified domestic purpose for the family unit.

5. Strategic Implications for Taxpayers, CAs, and CFOs

This decision serves as an invaluable precedent for tax planning, estate structuring, and capital gains tax management. Key strategic implications include:

1. Documentation vs. Practical Intent

While separate sale agreements will not automatically disqualify an exemption claim, taxpayers should maintain corroborative documentary evidence demonstrating single-family occupation, shared kitchen facilities, common utility bill management, or internal structural modifications linking the units' functional usage.

2. Adaptability to High-Density Urban Real Estate

Metropolitan markets like Mumbai, Delhi-NCR, and Bengaluru often lack sprawling single-family plots. High-net-worth investors acquiring multi-unit luxury floor spaces in high-rises can now confidently claim capital gains tax exemptions across combined floor spaces under Section 54F, provided the intent is family integration.

3. Audit Readiness & Litigation Strategy

Chartered Accountants and tax practitioners defending capital gain claims during scrutiny assessments should emphasize the beneficial and remedial nature of Section 54F. The provision was enacted by Parliament to encourage housing investments and must be interpreted liberally rather than hyper-technically.

6. Key Takeaways Checklist for Capital Gains Planning

• Asset Scope: Section 54F applies to LTCG generated from selling non-residential capital assets (e.g., commercial units, plots, gold, unlisted shares).
• Same Building Rule: Multiple flats acquired in the same building—even across different floors—can qualify as "one residential house" if dedicated to unified family living.
• Functional Evidence: Retain evidence showing common household operations, single joint family occupancy, or integrated living patterns.
• Reinvestment Timelines: Purchase must take place within 1 year before or 2 years after the date of asset transfer, or construction must be completed within 3 years.
• Proviso Compliance: Assessee must not own more than one residential house (other than the new asset) on the date of transfer of the original asset.

7. Conclusion & Expert Recommendation

The Mumbai ITAT ruling in Sunil Indravadan Shah vs. ITO (ITA No. 7276/MUM/2025) reinforces a pragmatic, commercial-reality-based tax regime that prioritizes functional substance over technical documentation. By holding that separate entrances and floor levels do not fragment a single residential unit, the tribunal provides clarity and strong legal protection to taxpayers investing substantial capital in Indian real estate.
