Home Loan Tax Benefits and Prepayment, Explained

Last updated: October 2026

A home loan is usually the biggest loan you'll take, so two things matter a lot: the tax you can save on it, and how much interest you can avoid by prepaying.

The two tax benefits

• Interest, Section 24(b): up to ₹2,00,000 a year of interest on a self-occupied home.
• Principal, Section 80C: up to ₹1,50,000 a year of principal repaid, within the overall 80C limit you share with PF, PPF, ELSS and others.

Both are available only under the old tax regime. The new regime doesn't allow the interest deduction on a self-occupied home, so if you have a large home loan, compare both regimes before choosing.

A worked example

Take a ₹50,00,000 loan at 8.5% for 20 years. The EMI is ₹43,391. In the first year you pay about ₹4,21,182 in interest and only about ₹99,511 in principal, so you easily use the full ₹2 lakh interest deduction.

For someone in the 30% slab on the old regime, deducting ₹2,00,000 interest plus ₹99,511 principal saves roughly ₹93,000 in tax that year, assuming the principal fits within their 80C limit.

Why prepaying early is powerful

Early EMIs are mostly interest. On the same ₹50 lakh loan, a one-time prepayment of ₹5,00,000 at the end of year one, keeping the EMI the same, shortens the loan from 20 years to about 16 years and saves about ₹16 lakh in interest.

Before prepaying, keep an emergency fund aside and check whether the interest you're saving beats what that money would earn elsewhere. Floating-rate home loans to individuals generally have no prepayment penalty.
