Home Loan Interest Deduction Tax Trap for AY 2026-27 (Tax Year 2025-26)

Introduction

Investing in residential real estate using bank financing has traditionally offered significant tax advantages to taxpayers in India. However, with the default transition to the New Tax Regime, many homeowners are facing a "Home Loan Tax Trap." For the Assessment Year 2026-27 (Tax Year 2025-26), the rules governing interest deductions under Section 24(b) and set-off of house property losses have been modified. Taxpayers who continue to claim home loan interest deductions under standard assumptions face disallowances and audit flags unless they reconcile their calculations with the default regime.

This guide decodes the mechanics of home loan interest claims, detailing the restrictions on self-occupied properties and loss set-offs.

Legal Reference Block

Relevant Sections of the Income Tax Act 2025:

• Section 24(b): Governs deductions for interest paid on capital borrowed for acquiring, constructing, repairing, or renewing property (capped at ₹2 Lakh for self-occupied under Old Regime).
• Section 115BAC: Disallows interest deductions under Section 24(b) for self-occupied properties for taxpayers opting for the New Tax Regime.
• Section 71(3B): Restricts the set-off of losses under the head "Income from House Property" against other heads of income for taxpayers in the New Tax Regime.

The Self-Occupied Property Restriction

For self-occupied residential property, the tax treatment differs between the two tax regimes:

1. Old Tax Regime: You can deduct up to ₹2,00,000 of interest paid under Section 24(b). This directly reduces your taxable salary income.
2. New Tax Regime (Default): Interest deduction under Section 24(b) for self-occupied property is zero. No deduction is allowed, and you cannot declare a negative income (loss) from self-occupied house property.

The Rented Property Loss Set-off Trap

For let-out (rented) properties, the interest paid under Section 24(b) is deductible from the rental income under both regimes. However, if your interest outgo is higher than the net rental income, a loss arises:

• Under the Old Tax Regime: You can set off house property loss against salary or other heads of income up to ₹2,0,000 in the same year. Any unabsorbed loss can be carried forward for up to 8 assessment years.
• Under the New Tax Regime: You can deduct the interest from the rental income to bring the taxable rent down to zero. However, if a loss remains, it cannot be set off against salary or other income. Furthermore, this loss cannot be carried forward to future years—it is permanently lost.

Break-even Calculation: Old vs. New Regime

Let's look at the math for a salaried individual with a home loan to see how the home loan tax trap affects their final tax liability.

Scenario Profile:

• Gross Salary: ₹15,00,000
• Annual Home Loan Interest (Self-occupied): ₹2,00,000
• Standard Deduction: ₹75,000 (New Regime) vs. ₹50,000 (Old Regime)
• Other Deductions (Section 80C, 80D under Old Regime): ₹2,00,000

Taxable Income Computation:

Applying the slab rates to these net incomes will show if the Old Regime is beneficial due to home loan interest. Homeowners with large home loans and high tax rates must run this comparison before filing.

Common Mistakes with Home Loans

• Double-Deducting in New Regime: Many taxpayers declare interest on self-occupied property expecting a deduction while filing under the default New Tax Regime, which is rejected by the CPC utility.
• Losing Pre-Construction Interest: Pre-construction interest must be claimed in 5 equal installments. In the New Tax Regime, these installments are disallowed for self-occupied properties.
• Incorrect Claim by Joint Owners: Joint owners can each claim up to ₹2 Lakh interest (under Old Regime), provided they are co-borrowers and co-owners. Claiming without co-ownership leads to disallowance.

Conclusion

Understanding the restrictions on Section 24(b) under the default New Tax Regime prevents unexpected tax demands. If you have substantial interest outgo on a self-occupied property, evaluate the math between regimes before filing your return.
