Home Loan Tax Benefits: Section 80C & Section 24 Explained

Published: July, 2026  ·  8 min read  ·  EMIPlan Editorial Team

A home loan isn't just a way to buy property - under the old tax regime, it's also one of the few remaining ways to meaningfully cut your taxable income. Between Section 24(b) on interest and Section 80C on principal, a single self-occupied home loan can shelter up to ₹3.5 lakh of income every year.

This guide breaks down exactly what you can claim, how much tax it actually saves, and why the new tax regime changes the picture entirely.

Old regime: up to ₹2,00,000 interest deduction (Section 24b) + up to ₹1,50,000 principal deduction (Section 80C) = up to ₹3,50,000 in combined deductions per year, per borrower.

Section 24(b): Deduction on Home Loan Interest

Section 24(b) lets you deduct the interest portion of your home loan EMI from your taxable income, under the head "Income from House Property."

Property Type Maximum Interest Deduction Notes
Self-occupied ₹2,00,000 / year Old tax regime only. Includes pre-construction interest, claimed in 5 equal instalments after possession.
Let-out (rented) No upper cap Full interest deductible against rental income. Loss set-off against salary capped at ₹2,00,000/year (old regime); no set-off against other income under the new regime.

Important: you can only start claiming Section 24(b) once you have possession of the property - interest paid during construction accumulates and is released in 5 equal annual instalments starting the year construction completes.

Section 80C: Deduction on Principal Repayment

The principal portion of your EMI, along with stamp duty and registration charges paid in the year of purchase, qualifies under Section 80C - up to ₹1,50,000 per year.

The ₹1,50,000 Section 80C limit is shared across all your 80C instruments combined - PPF, ELSS, life insurance premiums, EPF and home loan principal all draw from the same ₹1.5 lakh cap, not separate limits each.

There's also a clawback to know about: if you sell the property within 5 years of possession, every Section 80C deduction you claimed on it gets added back to your taxable income in the year you sell.

Worked Example: ₹50 Lakh Home Loan, Year 1

Take a ₹50 lakh home loan at 8.5% over 20 years (EMI ₹43,391). In the first year, the interest and principal split looks like this:

Interest Paid (Year 1)
₹4,21,182
Capped at ₹2,00,000 under Section 24(b) - the remaining ₹2,21,182 gets no deduction.
Principal Paid (Year 1)
₹99,511
Fully deductible under Section 80C (assuming no other 80C claims used up).
Total deduction: ₹2,99,511 (₹2,00,000 interest + ₹99,511 principal). At the 30% tax slab, that's roughly ₹89,853 saved in tax for the year - before cess. Note that in year 1 of a large home loan, interest alone often exceeds the ₹2 lakh cap, so a chunk of your actual interest cost gets no tax benefit at all.

Old Regime vs New Regime

This is the decision that matters most. Since the new tax regime became the default, home loan tax benefits are only available if you actively choose the old regime.

Benefit Old Regime New Regime (default)
Section 24(b) - self-occupied Available, up to ₹2L Not available
Section 80C - principal Available, up to ₹1.5L Not available
Interest on let-out property Fully deductible Deductible only against rental income, no cap - but no loss set-off against salary
Section 80EE / 80EEA (first-time buyers) Available if eligible Not available

The right choice depends on your numbers: the new regime offers lower slab rates and a higher standard deduction, but strips out every home-loan-linked benefit for a self-occupied property. As a rule of thumb, if your home loan interest alone exceeds ₹2 lakh a year and you're in the 20-30% tax bracket, the old regime is usually worth running the numbers on.

When the Old Regime Is Worth Choosing

When the New Regime May Work Out Better

There's no shortcut here - the only reliable way to decide is to compute your actual tax liability under both regimes using your real interest and principal figures for the year.

First-Time Buyer Add-Ons: Section 80EE and 80EEA

Beyond the standard ₹2L + ₹1.5L, some first-time buyers qualify for extra deductions - but both come with sanction-date windows that have since closed, so they only apply if your loan was sanctioned inside the eligible period:

Since the 80EEA sanction window closed on 31 March 2022, a fresh home loan taken today does not qualify for it - only borrowers still repaying a loan sanctioned inside that window can claim it.

Common Mistakes That Cost Borrowers Their Deduction

❌ Claiming interest before possession - Section 24(b) cannot be claimed on an under-construction property; pre-construction interest is only released in 5 instalments after possession.
❌ Forgetting stamp duty and registration - these qualify under Section 80C in the year of payment, but only that one year, and many buyers simply forget to include them.
❌ Not accounting for the shared 80C limit - if you're also investing in PPF or ELSS, your effective home-loan-linked 80C benefit shrinks accordingly, since it's one combined ₹1.5 lakh cap.

Frequently Asked Questions

How much tax can I save on a home loan?

Under the old regime, a self-occupied home loan can shelter up to ₹3,50,000 of income a year - ₹2,00,000 interest under Section 24(b) plus ₹1,50,000 principal under Section 80C. At a 30% tax slab, that's roughly ₹1,05,000 saved annually, though the exact figure depends on how much interest and principal you actually pay that year.

Can I claim home loan tax benefits under the new tax regime?

Not for a self-occupied property - the new tax regime removes both Section 24(b) and Section 80C deductions entirely for self-occupied homes. If the property is rented out, you can still deduct interest against rental income, but you can't set off any resulting loss against your salary the way the old regime allows.

Can both spouses claim tax benefits on the same home loan?

Yes - if both are co-borrowers and co-owners, each can independently claim up to ₹2,00,000 in interest and ₹1,50,000 in principal, effectively doubling the household's deduction on the same loan.
