How to Save Tax on a Home Loan (Sections 80C & 24b)

A home loan is a big commitment — but it's also one of the most powerful tax-saving tools available to an Indian household. Used well, the deductions can meaningfully cut your annual tax bill. Here's how the benefits work and how to get the most from them.

The two big deductions

Your EMI has two parts — principal and interest — and each has its own tax break under the old regime:

• Principal (Section 80C): up to ₹1.5 lakh a year, though this limit is shared with other 80C items like EPF, PPF, ELSS and insurance premiums.
• Interest (Section 24b): up to ₹2 lakh a year for a self-occupied home. For a let-out property, the rules differ.

Together, that's up to ₹3.5 lakh knocked off your taxable income in a year — real money back in your pocket.

Double it with a joint loan

Here's the underused trick: if you take the loan jointly with a co-owner (often a spouse) and both of you repay it, each can claim the deductions on your respective share. Two people claiming ₹2 lakh interest each means up to ₹4 lakh of interest deduction for the household. See joint home loans for the full picture — just ensure both are co-owners and co-borrowers.

Special first-timer benefits

From time to time, the government offers additional interest deductions for first-time buyers or affordable housing (such as under sections introduced in various budgets). These come and go and have conditions, so check what's currently available when you take your loan — it can add to your savings.

The regime decision matters

All of this assumes the old tax regime. The new regime trades these deductions for lower slab rates. If your home-loan deductions are large — full 80C plus ₹2 lakh interest — the old regime often wins; if not, the new one might. Run both before deciding: see old vs new tax regime.

Plan it through the year

Don't discover your deductions in March. Track your principal and interest split across the year so you know exactly what you can claim and which regime suits you. HomeFin's loan tracker shows your interest and principal breakdown, and keeps your other 80C investments in view — turning tax filing from a scramble into a summary. And remember: never take a bigger loan just for the tax break — the interest you pay always exceeds the tax you save.
