Tax Relief on Property Sales: Bengaluru ITAT Decodes Cost of Acquisition for High-Value Capital Gains
Landmark Ruling Expands Scope of Allowable Deductions Under Section 48 for Homebuyers
Landmark Judgment Resolves Long-Standing Conflict on Housing Loan Interest Capitalization
By Legal Editor
New Delhi: July 13, 2026:
The financial landscape of real estate transactions has experienced a significant shift following a definitive ruling by the Income Tax Appellate Tribunal (ITAT) Bengaluru Bench. In the case of Santanu Arun Nandi v. Assistant Commissioner of Income Tax, the tribunal ruled on a complex set of tax deductions that directly affect how long-term capital gains (LTCG) tax is calculated when a residential property is sold. This decision clarifies the interpretation of the "cost of acquisition" under Section 48 of the Income-tax Act, 1961, bringing substantial financial relief to property sellers, particularly Non-Resident Indians (NRIs) navigating the Indian tax structure.
By expanding the definitions of allowable structural expenses, the ITAT has established clear guidelines for incorporating peripheral real estate costs into the primary financial base of an asset. This analytical review evaluates the regulatory framework, judicial precedents, and practical compliance outcomes that arise from this significant development.
Expanding Section 48: The Capitalization of Incidental Property Costs
At the core of the legal debate was the structural configuration of Section 48 of the Income-tax Act, 1961. This provision defines the mechanism for computing capital gains by deducting the cost of acquisition, the cost of any improvement, and expenditures incurred wholly and exclusively in connection with the transfer from the full value of consideration.
Historically, revenue authorities have limited the "cost of acquisition" to the plain purchase price specified in the sale deed. However, the ITAT Bengaluru Bench departed from this rigid interpretation by categorizing mandatory ancillary outflows as intrinsic components of the capital acquisition process.

Net Taxable Long-Term Capital Gains (LTCG)
Statutory Inclusions Under the New Precedent
One-Time Maintenance Deposits: Property developers frequently require buyers to pay a upfront maintenance deposit before hand-over. The tribunal noted that because these payments are mandatory to secure possession of the flat, they are part of the acquisition cost. If these funds are not recovered from the subsequent buyer, they can be indexed to reduce long-term capital gains tax.
Utility Infrastructure Deposits: Capital paid to builders for electricity and water connections has been granted identical status. The tribunal ruled that these payments are indispensable for rendering the asset functional and legally inhabitable, allowing them to qualify for indexation benefits.
This legal positioning recognizes that the cost of an asset encompasses all financial burdens that a buyer must clear to secure undisputed, operational ownership.
Harmonizing Section 24(b) and Section 48: Eliminating Double Deduction Concerns
The most intricate legal challenge addressed in the ruling is the tax treatment of home loan interest. Under the Income-tax Act, 1961, interest paid on capital borrowed for property acquisition is explicitly deductible under Section 24(b) under the head "Income from House Property."
The Revenue Department has long argued that allowing a taxpayer to add this interest to the cost of acquisition under Section 48 when selling the asset constitutes an impermissible "double deduction."

To resolve this conflict, the ITAT relied on the landmark Karnataka High Court judgment in CIT v. Sri Hariram Hotels Pvt. Ltd. (2010), which built on the foundational principles of CIT v. Maithreyi Pai (1985). These precedents state that Section 24(b) and Section 48 operate under entirely distinct heads of income.
The statutory framework does not automatically block an expense from influencing capital gains calculations just because it is an interest cost. The crucial compliance rule established by the ITAT is mutual exclusivity in practice:
"If a taxpayer has not actively claimed tax deductions for housing loan interest under Section 24(b) in past income tax returns, that unhedged interest cost directly transforms into an expenditure incurred to acquire the asset. It can then be legitimately included in the cost of acquisition when computing capital gains under Section 48."
In the current case, the taxpayer provided historical income tax returns to prove that no prior deduction had been claimed under Section 24(b), verifying the structural integrity of the asset's cost base.
Evidentiary Standards and Evaporation of Unverified Deductions
While the tribunal expanded definitions for asset-linked deposits and interest, it maintained strict standards regarding transfer expenses. The taxpayer sought to deduct international travel expenses, claiming the journey from the United States to India was undertaken solely to finalize the real estate sale.
The Income Tax Department disallowed the claim, arguing the expense lacked a verified, exclusive link to the property transfer. Rather than dismissing the claim outright based on strict legal bars, the ITAT chose a balanced approach by remanding the issue back to the Assessing Officer.
This directive requires the assessing authority to review the timeline, correspondence, and documentation to determine if the travel was executed "wholly and exclusively" for the transaction. This emphasizes that while incidental costs are legally permissible under Section 48, the burden of proof rests entirely on the taxpayer. Without detailed logs and transaction records, the expenditure will be disallowed.
Navigating Condonation of Delay and Jurisdictional Protocols
Beyond capital gains adjustments, this ruling provides insight into procedural tax litigation. Due to a filing mistake, the taxpayer's appeal faced a substantial delay of 737 days. The taxpayer had mistakenly approached the Commissioner of Income Tax (Appeals) instead of filing directly with the ITAT after receiving a directive from the Dispute Resolution Panel (DRP).
The ITAT chose to condone the delay, noting that the error stemmed from pursuing a remedy in the wrong forum rather than bad faith or negligence. This procedural flexibility reflects a judicial preference for resolving tax disputes on their substantial legal merits rather than dismissing them over technical procedural errors.
Conclusion: Key Compliance Steps for Property Investors
The ITAT Bengaluru decision clarifies how taxpayers can optimize their tax positions when selling real estate. It confirms that the cost of acquisition is a dynamic figure that includes mandatory builder deposits and unhedged loan interest alongside the initial purchase price.
For long-term financial planning, property owners should maintain organized records of all initial payments, utilities infrastructure outlays, and annual home loan statements. Keeping detailed tax documents ensures these expenses can be successfully verified during future capital gains calculations.

Category A: Asset Acquisition Cost Components
Q1: Can regular monthly society maintenance charges be added to the cost of acquisition when selling property?
No. Regular monthly or quarterly maintenance charges paid to a housing society or residents' association are operational expenses for upkeeping the property. They cannot be capitalized under Section 48.
Only one-time, mandatory maintenance deposits paid directly to the builder to secure initial possession qualify as part of the cost of acquisition, provided they were not refunded or separately recovered from the subsequent buyer.
Q2: Why are electricity and water infrastructure deposits eligible for indexation benefits?
The ITAT Bengaluru Bench clarified that these one-time payments are compulsory expenses required to make the residential unit functional and legally inhabitable. Because the property cannot be used or possessed without these utilities, they are treated as part of the necessary cost of acquiring the capital asset, making them eligible for indexation benefits under Section 48(ii).
Category B: Home Loan Interest Capitalization
Q3: Does adding home loan interest to the cost of acquisition create an illegal double deduction?
It only becomes a double deduction if the taxpayer claims the same interest under both provisions.
If you have already used the interest to reduce your taxable income under Section 24(b) (under "Income from House Property") in past years, you cannot include that same amount under Section 48. However, if you never claimed the deduction under Section 24(b), you are legally permitted to add that interest to the cost of acquisition.
Q4: What documentation must a taxpayer provide to capitalize housing loan interest under Section 48?
Taxpayers must provide two main types of documentation:
Interest Certificates: Detailed year-by-year loan account statements from the bank or financial institution showing the exact interest accrued and paid.
Historical Income Tax Returns (ITRs): Copies of ITR filings for the entire holding period of the property to prove that the interest was not claimed as a deduction under Section 24(b).
Category C: Transfer Expenses & Proof Requirements
Q5: Under what conditions can travel expenses be deducted from the total sale consideration of a property?
To qualify for a deduction under Section 48(i), travel expenses must be incurred wholly and exclusively in connection with the transfer of the asset.
The taxpayer must provide clear evidence, such as passport stamps, air tickets, and meeting records, showing the travel was necessary to execute the sale deed or handle essential transaction procedures, rather than for personal or general purposes.
Q6: What happens if an Assessing Officer disallows an incidental cost claim during an audit?
If the Assessing Officer disallows a claim due to insufficient documentation, the amount is removed from the cost base, which increases the calculated capital gains and results in higher tax liability, along with potential interest charges under Section 234B and Section 234C.
Taxpayers can appeal this decision to the Commissioner of Income Tax (Appeals) or the ITAT, provided they have additional supporting evidence to verify the expenses.
Category D: Procedural Remedies & Appeal Timelines
Q7: What is the correct appellate path after receiving an unfavourable order linked to the Dispute Resolution Panel (DRP)?
When an assessment order is finalized based on directions from the Dispute Resolution Panel (DRP), the subsequent appeal must be filed directly with the Income Tax Appellate Tribunal (ITAT). Filing an appeal with the Commissioner of Income Tax (Appeals) in this scenario is a jurisdictional error.
Q8: How does the ITAT handle significant delays caused by filing an appeal in the wrong forum?
Under Section 253 of the Income-tax Act, if a taxpayer files an appeal late because they were pursuing a remedy in the wrong forum, the ITAT may condone the delay.
The taxpayer must demonstrate that the mistake was an honest error made while seeking relief and was not an intentional attempt to delay proceedings.
