Home Loan Tax Benefits Explained (FY 2025-26)
A home loan can cut your income tax in two ways, but only under the old tax regime: the interest you pay is deductible up to ₹2,00,000 a year for a self-occupied home under Section 24(b), and the principal you repay counts under Section 80C within the overall ₹1,50,000 limit. The default new regime allows neither for a self-occupied home. These are FY 2025-26 (AY 2026-27) rules and this is general information, not tax advice.
Section 24(b): the interest deduction
Section 24(b) lets you deduct the interest portion of your EMIs. For a self-occupied home the cap is ₹2,00,000 a year. For a let-out (rented) home there’s no cap on the interest itself — but the net loss from house property that you can set off against your other income is limited to ₹2,00,000, with any excess carried forward for up to eight years.
Because early EMIs are mostly interest, most borrowers hit the ₹2 lakh cap easily in the first several years of a sizeable loan.
Section 80C: the principal deduction
The principal you repay each year qualifies under Section 80C, up to ₹1,50,000. The catch is that this ceiling is shared with everything else under 80C — EPF, PPF, ELSS, life-insurance premiums, children’s tuition and so on. If those already fill the ₹1.5 lakh, your loan principal adds nothing extra. Stamp duty and registration charges paid in the year you buy also count toward this limit.
A worked example
Take a ₹30,00,000 home loan at 8.5% over 20 years. In year one the amortization schedule shows about ₹2,52,709 of interest and ₹59,707 of principal. The interest exceeds the ₹2 lakh cap, so your Section 24(b) deduction is ₹2,00,000; the ₹59,707 of principal fits inside Section 80C.
For someone with a ₹15,00,000 salary choosing the old regime, deductions like these reduce the year’s tax by roughly ₹93,600. Run your own figures in the home loan tax-benefit calculator — it reads the interest and principal straight from your loan schedule.
The new-regime catch
Here’s what trips people up. The new regime is the default, and for a self-occupied home it gives you none of the above. But it also has wider slabs and a rebate that makes income up to ₹12 lakh tax-free, so many borrowers still pay less under it — even after losing the deductions. Whether the old regime’s deductions beat the new regime’s lower rates depends entirely on your numbers; see old vs new regime for home-loan borrowers.
Because tax rules shift with every Budget, treat all of this as a starting point and confirm your position with a chartered accountant.
