Home Loan Tax Benefits: Section 24(b) and 80C Explained (2026)
Short version: Under the old tax regime, you can claim up to ₹2 lakh a year on home loan interest under Section 24(b) (for a self-occupied property) and up to ₹1.5 lakh a year on principal repayment under Section 80C (shared with EPF, ELSS, insurance, and other 80C instruments). The new tax regime does not allow either deduction for a self-occupied home. Which regime wins depends on how much of your 80C limit you'd use anyway and how large your interest outgo is — run both numbers before assuming either one is better by default.
Section 24(b): the interest deduction
Section 24(b) lets a self-occupied homeowner deduct home loan interest paid during the year from taxable income, up to ₹2 lakh annually. A few details that trip people up:
- The ₹2 lakh cap applies per person, not per loan — if you and your spouse are co-borrowers and co-owners, you can each claim up to ₹2 lakh against your respective shares of the interest, effectively doubling the household benefit.
- For a let-out (rented) property, there's no cap on the interest deduction — you can offset the full interest against rental income, though any resulting loss that can be set off against other income is capped at ₹2 lakh per year, with the excess carried forward.
- The deduction is only available if construction is completed — for an under-construction property, interest paid during construction is aggregated and deducted in five equal instalments starting the year construction finishes, on top of that year's regular interest.
Section 80C: the principal deduction
Section 80C lets you deduct home loan principal repayment up to ₹1.5 lakh a year — but this limit is shared across every 80C instrument you use: EPF contributions, life insurance premiums, ELSS mutual funds, PPF, and others. For most salaried borrowers with EPF contributions already eating into this limit, the home loan principal component often doesn't add much marginal benefit, since the ₹1.5 lakh ceiling may already be reached by EPF alone.
There's also a 5-year lock-in: if you sell the property within 5 years of possession, any 80C deduction you claimed on principal gets reversed and added back to your income in the year of sale.
Old regime vs new regime
The new tax regime (the default since a few years back) does not allow the Section 24(b) deduction for a self-occupied home, nor the Section 80C deduction. It offers lower slab rates in exchange for giving up most deductions. This makes the choice regime-dependent:
- If your 80C limit is already used up by EPF and other mandatory contributions, and your loan interest is modest, the old regime's home loan benefit may not outweigh the new regime's lower slab rates.
- If you have a large loan with substantial interest (common in the first several years of a big loan) and haven't maxed 80C elsewhere, the old regime's deductions can be worth a meaningful amount — sometimes several tens of thousands of rupees a year in tax saved, depending on your slab.
There's no universal answer — run both regimes through an actual tax calculation with your real interest and principal figures before choosing, ideally every year, since your interest component shrinks over the loan's life.
How this affects your effective loan rate
If you're in the old regime and actually benefit from Section 24(b), your effective interest rate is lower than the stated rate — roughly, multiply your stated rate by (1 − your marginal tax rate), capped by the ₹2 lakh deduction ceiling. On a ₹50 lakh loan at 9%, if your full interest is within the deductible range and you're in the 30% slab, your effective rate is closer to 6.3% rather than 9% — which matters when you're comparing prepayment against other investments (see our prepay vs PPF comparison for how this shifts the math).
What this means when you prepay
Prepaying reduces your interest paid, which slightly reduces your Section 24(b) deduction going forward — but the net effect is still positive for almost every borrower, because you save more in interest than you lose in tax benefit. The deduction is a partial offset to the cost of the loan, not a reason to keep a bigger loan than you need.

Frequently asked questions
How much home loan tax benefit can I claim in 2026? Under the old regime, up to ₹2 lakh a year on interest (Section 24(b), self-occupied property) and up to ₹1.5 lakh a year on principal (Section 80C, shared with other 80C instruments). The new regime does not allow either deduction for a self-occupied home.
Can both spouses claim home loan tax benefits? Yes, if both are co-borrowers and co-owners, each can claim up to ₹2 lakh under Section 24(b) and up to ₹1.5 lakh under Section 80C against their respective share of the loan — effectively doubling the household deduction, subject to each person's own 80C usage.
Is the home loan tax benefit available under the new tax regime? No, the new tax regime does not allow the Section 24(b) interest deduction or the Section 80C principal deduction for a self-occupied property. You'd need to be in the old regime to claim either.
Does prepaying my home loan reduce my tax benefit? Yes, slightly — less interest paid means a smaller Section 24(b) deduction over time. But the interest you save from prepaying is almost always larger than the tax benefit you give up, so prepayment still comes out ahead for most borrowers.
