Home Loan Tax Benefits - Section 24, 80C and Joint Loan Deductions

Home Loan Tax Benefits: Every Deduction You Can Actually Claim

A home loan is the largest debt most people ever take. The good news is that the tax system gives you back a meaningful chunk of it, if you know which sections to claim and how they stack.

But there's a catch that trips up almost everyone now: most of these benefits only exist under the old tax regime. Pick the new regime and the headline deductions vanish. Here's the full map, and how to know if your home loan is even worth claiming.

The Two Big Deductions

A home loan EMI has two parts: interest and principal. Each gets its own section.

• Interest, Section 24(b): up to ₹2,00,000 a year for a self-occupied home.
• Principal, Section 80C: up to ₹1,50,000 a year, but this shares the same ₹1.5 lakh 80C bucket as your EPF, PPF, and ELSS.

So in the early years of a loan, when the EMI is mostly interest, Section 24(b) does the heavy lifting. The principal deduction is often already used up by your EPF and other 80C investments.

Notice the interest is capped at ₹2 lakh even though you paid far more. That cap is the single biggest limit on home loan tax savings for a self-occupied home.

Don't Forget Stamp Duty and Registration

Here's a one-time benefit people miss. The stamp duty and registration charges you pay when buying the home are deductible under Section 80C, in the year you pay them. On a property worth ₹50 lakh, stamp duty alone can be ₹2–3 lakh, so this can fill your entire 80C cap in your purchase year. Claim it.

The New Regime Changes Everything

This is the part that catches people out.

Under the new tax regime, you cannot claim Section 24(b) interest on a self-occupied home, and you cannot claim Section 80C principal at all. The deductions simply don't exist there.

So if your home loan deductions are large, that's a strong reason to stay on the old regime. Run both regimes side by side before deciding. The income tax FY 2026-27 guide walks through exactly that comparison, and a real ₹40 lakh-loan example where the old regime wins because of home loan interest and HRA.

Let-Out vs Self-Occupied: A Big Difference

If you rent the property out, the rules change.

For a let-out property, there's no ₹2 lakh cap on the interest deduction itself. You can deduct the full interest against the rental income. But the "loss from house property" that you can set off against your other income (like salary) in a year is capped at ₹2 lakh. Any unabsorbed loss carries forward for up to 8 years.

For a self-occupied property, the ₹2 lakh cap is firm. There's no rent, so the whole thing is a deduction against your salary, limited to ₹2 lakh.

Joint Home Loan: The Smartest Move

Here's how couples legitimately double the benefit.

If a property is jointly owned and both spouses are co-borrowers on the loan, each co-owner can claim up to ₹2 lakh interest and up to ₹1.5 lakh principal, in proportion to their share. Two earning co-owners can therefore claim up to ₹4 lakh interest and ₹3 lakh principal between them.

The conditions are strict: both must be co-owners of the property and co-borrowers on the loan, and each must actually contribute to the EMI from their own income. Put one spouse's name only on the paper and it won't hold up.

What About Pre-Construction Interest?

If you took the loan while the home was still being built, the interest you paid during construction isn't lost. You claim it in five equal instalments, starting from the financial year in which construction completes. It still falls within the overall ₹2 lakh annual cap for a self-occupied home, though.

Work out your EMI and the interest split year by year with the Home Loan EMI calculator, then test whether the old or new regime wins for you using the Income Tax calculator and the income tax FY 2026-27 guide. To plan the 80C side around your principal repayment, see the Section 80C guide.
