Section 24(b): Rs 2,00,000 home-loan interest cap on self-occupied property and the 5-year completion rule

For most salaried buyers in India, the home-loan interest deduction under Section 24(b) of the Income-tax Act, 1961 is the single largest tax break tied to a house. For a self-occupied property, that deduction is capped at Rs 2,00,000 a year, and the cap only applies in full if the purchase or construction is finished within 5 years. Miss the 5-year window and the ceiling collapses to Rs 30,000. This guide walks through the statute, a worked example on a Rs 40,00,000 loan, the mistakes that surface in ITR scrutiny, and the questions readers ask most.

What the Section Says

Section 24(b) allows a deduction for interest payable on capital borrowed for acquiring, constructing, repairing, renewing or reconstructing a house property. The way that interest is capped depends entirely on how the property is used.

For a self-occupied house, the deduction is limited to Rs 2,00,000 in a financial year, provided the loan was taken on or after 1 April 1999 for purchase or construction, and that purchase or construction is completed within 5 years from the end of the financial year in which the capital was borrowed. If the loan predates 1 April 1999, or is taken for repair and renovation, or the 5-year completion condition is not met, the ceiling drops to Rs 30,000. The statutory text is published by the Income Tax Department at incometaxindia.gov.in and the consolidated bare Act sits on indiacode.nic.in.

For a let-out property, there is no Rs 2,00,000 ceiling on the interest itself. The full interest for the year is deductible against the annual rental value after the 30% standard deduction under Section 24(a). However, the loss from house property that a taxpayer can set off against other heads of income in the same year is capped at Rs 2,00,000 under Section 71(3A), with any excess carried forward for up to 8 assessment years.

There is a second timing rule that catches most first-time buyers. Pre-construction interest - the interest paid from the date of borrowing up to the end of the financial year immediately before the year in which construction is completed - is not lost. It is aggregated and allowed as a deduction in 5 equal annual instalments, starting from the year the construction is finished. Those instalments still sit inside the Rs 2,00,000 self-occupied ceiling for each of those 5 years.

One point that trips up buyers who moved to the default regime: under the new tax regime of Section 115BAC, the Section 24(b) deduction for a self-occupied property is not allowed at all. The Rs 2,00,000 benefit survives only under the old regime. For a let-out property under the new regime, the interest deduction is allowed, but the resulting house-property loss cannot be set off against salary or other heads. Because this single deduction can swing the old-versus-new decision, run both scenarios on the old vs new regime calculator before you lock your choice for the year.

Worked Example

Consider Ananya, a salaried employee in Pune with a gross salary of Rs 18,00,000 for FY 2025-26. In April 2024 she took a home loan of Rs 40,00,000 at 8.5% per annum to buy a flat she occupies herself, and possession was handed over in the same financial year, comfortably inside the 5-year window.

In the first full year of repayment, the interest component of her EMIs works out to roughly Rs 3,36,000 on the opening balance. That figure exceeds the self-occupied ceiling, so her Section 24(b) deduction is restricted to Rs 2,00,000. You can reproduce her interest schedule on the home-loan EMI calculator and see how the interest share shrinks each year.

Under the old regime, Ananya claims the Rs 2,00,000 interest deduction plus the principal repayment under Section 80C, capped at Rs 1,50,000, plus the standard deduction of Rs 50,000. The Rs 2,00,000 interest deduction alone saves tax at her marginal rate; at the 30% slab that is about Rs 60,000 of tax plus the 4% health and education cess, roughly Rs 62,400 in real money. Model the full computation on the income-from-house-property calculator.

Had Ananya instead let the flat out, her entire Rs 3,36,000 interest would be deductible against the rent, and the shortfall would create a house-property loss - but her set-off against salary in the same year would still be capped at Rs 2,00,000 under Section 71(3A), with the balance carried forward for 8 assessment years. First-time buyers who satisfy the loan-sanction conditions of Section 80EE can also test an additional Rs 50,000 interest deduction on the Section 80EE calculator.

Common Mistakes

The department's processing systems and manual scrutiny catch the same errors year after year. Here are the ones worth guarding against for AY 2026-27.

Claiming the deduction before possession. Interest that accrues during construction is pre-construction interest and cannot be claimed in the year it is paid. It is deductible only in 5 equal instalments from the year construction is completed. Claiming it early is the most common Section 24(b) adjustment under Section 143(1).

Ignoring the 5-year completion rule. If construction runs past 5 years from the end of the financial year in which the loan was taken, the self-occupied ceiling falls from Rs 2,00,000 to Rs 30,000. Buyers of delayed under-construction flats frequently claim the full Rs 2,00,000 when they are only entitled to Rs 30,000.

Claiming Section 24(b) on a self-occupied house in the new regime. As noted, the self-occupied interest deduction is unavailable under Section 115BAC. Taxpayers who switched to the default new regime but continued to claim Rs 2,00,000 receive a proposed adjustment. If you are unsure which regime you are in, the income-tax calculator shows both side by side.

Double-counting interest between co-borrowers. In a joint loan, each co-owner who is also a co-borrower may claim up to Rs 2,00,000 on their share, but the total claimed cannot exceed the interest actually paid. Both spouses claiming Rs 2,00,000 each on a loan whose annual interest is Rs 3,00,000 is a mismatch the Annual Information Statement will flag.

Missing the lender's interest certificate. The Rs 2,00,000 or Rs 30,000 claim must match the interest certificate issued by the bank or housing finance company. A figure that does not reconcile with the reported interest is a routine scrutiny trigger under the faceless assessment scheme.

FAQ

Can I claim both Section 24(b) and Section 80C on the same home loan?

Yes. Interest is deducted under Section 24(b), capped at Rs 2,00,000 for a self-occupied house, while the principal repayment is deducted under Section 80C within the overall Rs 1,50,000 ceiling. They are separate deductions, but both are available only under the old tax regime.

Is the Rs 2,00,000 limit per person or per property?

It is effectively per person for a self-occupied property. In a joint home loan, each co-owner who is also a co-borrower can claim up to Rs 2,00,000 against their share of the interest, so long as the combined claim does not exceed the interest actually paid for the year.

Does the Rs 2,00,000 cap apply to a let-out property?

No. For a let-out property the full year's interest is deductible under Section 24(b). What is capped at Rs 2,00,000 is the house-property loss you can set off against other income in the same year under Section 71(3A); the rest is carried forward for up to 8 assessment years.

What happens if my flat is completed after 5 years?

The self-occupied interest ceiling drops from Rs 2,00,000 to Rs 30,000 for that property. The 5 years are counted from the end of the financial year in which the loan was taken, so document your possession date carefully.

Can I claim home-loan interest under the new tax regime?

For a self-occupied house, no - the Section 24(b) deduction is not available under the new regime of Section 115BAC. For a let-out house, the interest is deductible, but any resulting loss cannot be set off against salary or other heads.

How is pre-construction interest treated?

Interest paid from the borrowing date up to the end of the financial year before completion is aggregated and allowed in 5 equal annual instalments, beginning in the year construction is finished. Each instalment still counts towards the Rs 2,00,000 self-occupied ceiling for that year.

Which is the authoritative source for these limits?

The statutory language is on the Income Tax Department portal at incometaxindia.gov.in and in the consolidated bare Act on indiacode.nic.in. Always reconcile your claim with the lender's interest certificate before filing.
