Section 24(b): the Rs 2 lakh home-loan interest deduction on a self-occupied house and its conditions

Buying a home on a loan is, for most salaried Indians, the single largest financial commitment they will make, and Section 24(b) of the Income-tax Act 1961 is the provision that softens the interest bill at tax time. For the financial year 2025-26 (assessment year 2026-27), interest paid on a housing loan for a self-occupied property is deductible up to Rs 2,00,000 a year, but only if you stay in the old tax regime and only if your loan ticks a precise set of conditions. Miss one condition and the ceiling collapses to Rs 30,000, a figure that has not moved since the late 1990s.

This guide walks through exactly what the statute allows, runs the numbers on a real salary, and lists the errors that surface most often during Income Tax Department scrutiny. Every figure below is drawn from the Income-tax Act 1961 and current Oquilia rate data, so you can claim with confidence rather than guesswork.

What the Section Says

Section 24 has two limbs. Clause (a) gives a flat 30% standard deduction on the net annual value of a let-out property, and clause (b), the focus here, allows a deduction for interest on capital borrowed to acquire, construct, repair, renew or reconstruct house property. For a self-occupied house the annual value is treated as nil, so there is no rental income to tax, yet the law still lets you claim the interest as a loss under the head "Income from House Property".

The headline number is Rs 2,00,000 per financial year, but it is conditional. To claim the full Rs 2,00,000 against a self-occupied house, the loan must have been taken on or after 1 April 1999, it must be for acquisition or construction (not mere repair), and the acquisition or construction must be completed within five years from the end of the financial year in which the loan was taken. If any of those fail, the deduction is restricted to Rs 30,000. The table below sets out the two ceilings side by side.

A crucial structural point: because a self-occupied house generates no income, claiming interest creates a loss under the house-property head. Section 71(3A) caps the set-off of house-property loss against other heads of income, such as salary, at Rs 2,00,000 in any one year. Any unabsorbed loss can be carried forward for up to eight assessment years, but in those later years it can only be set off against house-property income. This interaction with carry-forward of losses is why the Rs 2,00,000 figure appears both as the Section 24(b) limit and as the annual set-off limit.

The single most important caveat for 2025-26: this deduction is available only under the old tax regime. Under the default new regime in Section 115BAC, the Rs 2,00,000 interest deduction against a self-occupied house is not allowed. Before claiming, run your numbers through the Oquilia old vs new regime calculator to confirm the old regime still works out cheaper for you once this deduction is in play. You can read the bare provision yourself; the Income from House Property rules form the backbone of the calculation.

Worked Example

Consider Priya, a salaried professional in Bengaluru, drawing a gross salary of Rs 14,00,000 in FY 2025-26. She bought a flat in 2023 with a home loan and paid Rs 2,40,000 in interest during the year, along with Rs 1,50,000 of principal (eligible under Section 80C) and a health premium of Rs 25,000 under Section 80D. Because she occupies the flat herself, her interest claim is capped at Rs 2,00,000, even though she actually paid Rs 2,40,000.

Her old-regime computation looks like this. The standard deduction in the old regime is Rs 50,000, the Section 24(b) house-property loss is the capped Rs 2,00,000, Section 80C absorbs Rs 1,50,000 and Section 80D another Rs 25,000.

On Rs 9,75,000 under the old-regime slabs (nil up to Rs 2,50,000; 5% from Rs 2,50,000 to Rs 5,00,000; 20% from Rs 5,00,000 to Rs 10,00,000), the tax works out to Rs 12,500 plus Rs 95,000, which is Rs 1,07,500, and after the 4% health and education cess the liability is Rs 1,11,800.

Had Priya not claimed Section 24(b), her taxable income would have been Rs 11,75,000, pushing Rs 1,75,000 into the 30% slab. Her tax would have been Rs 1,65,000 plus 4% cess, or Rs 1,71,600. The Rs 2,00,000 deduction therefore saves her Rs 59,800 in a single year: Rs 1,75,000 taxed at 30% and Rs 25,000 at 20%, grossed up by cess. To model your own salary, the Oquilia income tax calculator applies these slabs automatically.

Pre-construction interest

Interest paid before the year of completion is not lost. The Act allows you to aggregate interest from the borrowing date up to 31 March preceding the year of completion, and then claim it in five equal annual instalments starting from the year the construction is completed. This pre-construction interest competes for the same Rs 2,00,000 ceiling, so it does not give you extra headroom.

Suppose Priya had paid Rs 3,00,000 of interest during the construction period before her flat was completed. She would claim Rs 60,000 a year for five years, in addition to the current-year interest, but the combined figure each year is still bounded by Rs 2,00,000 for a self-occupied house.

Common Mistakes

The first and most expensive error in 2025-26 is claiming Section 24(b) interest against a self-occupied house while filing under the new regime. The Income Tax Department's processing system disallows it automatically under Section 143(1)(a), and the demand notice that follows is a common trigger for the prima-facie adjustment process. If you receive one, our guide on how to respond to a Section 143(1)(a) notice explains the e-Proceedings workflow.

A second frequent slip is claiming the full Rs 2,00,000 when construction overran the five-year deadline. If the loan was taken in FY 2018-19 and possession came only in FY 2025-26, more than five years after the end of FY 2018-19, the ceiling is Rs 30,000, not Rs 2,00,000. Taxpayers also wrongly claim interest on a loan used for renovation at the Rs 2,00,000 rate, when renovation loans are restricted to Rs 30,000.

Third, many borrowers forget that only the interest component qualifies under Section 24(b); the principal repayment belongs under Section 80C, where it shares the Rs 1,50,000 ceiling with provident fund, life insurance and ELSS. Mixing the two, or double-counting the EMI, is a classic scrutiny flag. Your lender's annual interest certificate splits the EMI into principal and interest precisely so you can allocate them correctly.

Fourth, co-borrowers often miss out. Where two co-owners are also co-borrowers, each can claim up to Rs 2,00,000 separately, provided each contributes to the EMI from their own funds and their ownership shares are documented. Claiming the deduction in one spouse's hands when the other paid the EMI invites disallowance.

FAQ

Is the Rs 2,00,000 limit available in the new tax regime?

No. For a self-occupied house the Section 24(b) deduction of up to Rs 2,00,000 is allowed only in the old regime. Under Section 115BAC, the new regime, this interest deduction against a self-occupied property is not permitted, which is why the old-versus-new comparison matters before you file.

Can I claim interest above Rs 2,00,000?

For a self-occupied house, no; the deduction is capped at Rs 2,00,000 even if you paid more, as in Priya's case where Rs 2,40,000 of interest yielded only a Rs 2,00,000 claim. For a let-out property, there is no per-property cap on the interest, though the overall house-property loss you can set off against other income is limited to Rs 2,00,000 a year under Section 71(3A).

What happens to interest paid before the house was ready?

Pre-construction interest, accumulated up to 31 March before the year of completion, is allowed in five equal annual instalments from the year of completion. It is added to the current year's interest but the combined claim for a self-occupied house still cannot exceed Rs 2,00,000 in any year.

Can both spouses claim the deduction on the same house?

Yes, where both are co-owners and co-borrowers and each services the loan from their own income. Each can claim up to Rs 2,00,000, effectively doubling the household deduction to Rs 4,00,000, provided ownership and repayment are properly documented in the ITR.

Does Section 80C overlap with Section 24(b)?

No, they are separate. Section 24(b) covers the interest portion of your home-loan EMI up to Rs 2,00,000, while the principal repayment is a tax deduction under Section 80C within the combined Rs 1,50,000 ceiling. You can claim both in the same year under the old regime.

When does the Rs 30,000 limit apply instead of Rs 2,00,000?

The Rs 30,000 ceiling applies if the loan was taken before 1 April 1999, if it was for repair, renewal or reconstruction rather than acquisition or construction, or if the property was not completed within five years from the end of the financial year in which the loan was taken.

Can I carry forward unabsorbed home-loan interest?

Yes. Where the house-property loss exceeds the Rs 2,00,000 set-off limit in a year, the balance can be carried forward for up to eight assessment years, but in those years it can only be set off against income under the house-property head.
