A home loan is one of the few borrowings in India where the government effectively shares the cost with you — through tax deductions on both the principal you repay and the interest you pay. Understanding home loan tax benefits properly can save you tens of thousands of rupees a year, but there's a big 2026 catch most borrowers miss: these benefits largely depend on which tax regime you choose. This guide breaks down Section 80C, Section 24(b), the regime trap, and how to claim everything you're entitled to.
The two main home loan tax benefits
A home loan EMI has two parts — principal and interest — and each is treated differently under the Income Tax Act.
| Section | What it covers | Maximum deduction (per year) | Key condition |
|---|---|---|---|
| 80C | Principal repayment | Up to ₹1.5 lakh | Shared with other 80C items; property not sold for 5 years |
| 24(b) | Interest paid | Up to ₹2 lakh (self-occupied) | Construction completed within 5 years |
| 80EEA | Extra interest (affordable housing) | Up to ₹1.5 lakh | Only for loans sanctioned in the eligible window — now closed for new loans |
Treat these as the headline limits. The amount you actually save is the deduction multiplied by your income tax slab rate, so a higher earner benefits more from the same deduction.
Section 80C — principal repayment
The principal portion of your EMI qualifies for deduction under Section 80C, up to ₹1.5 lakh a year. The important nuance: this ₹1.5 lakh limit is shared with everything else under 80C — EPF, PPF, ELSS mutual funds, life insurance premiums, children's tuition fees and more. If those already fill your ₹1.5 lakh, your home loan principal adds no extra benefit.
A bonus: the stamp duty and registration charges you pay when buying the property are also deductible under 80C — but only in the year you incur them, and within the same ₹1.5 lakh cap.
One catch worth remembering: if you sell the property within 5 years of the end of the financial year in which you took possession, the 80C deductions you already claimed get reversed and added back to your income.
Section 24(b) — interest paid
The interest portion is usually where the bigger saving sits. Under Section 24(b), you can deduct interest of up to ₹2 lakh per year on a self-occupied property. Given that early EMIs are mostly interest, many borrowers hit or approach this ceiling in the first several years of a 20-year loan.
Two conditions matter:
- The construction (or purchase) must be completed within 5 years from the end of the financial year in which the loan was taken. Miss it, and the cap drops to just ₹30,000.
- Interest paid before possession (the "pre-construction" period) isn't lost — it can be claimed in five equal instalments starting from the year you get possession, still within the overall ₹2 lakh annual limit.
For a let-out (rented) property, the full interest is technically deductible against rental income, but the net loss you can set off against your other income (salary, etc.) in a year is capped at ₹2 lakh; any excess carries forward for up to 8 years.
The 2026 catch: old regime vs new regime
This is the single most important point in this guide. Sections 80C and 24(b) for a self-occupied home are available only under the OLD tax regime. The new tax regime is now the default in India, and under it you generally cannot claim the ₹1.5 lakh 80C principal deduction or the ₹2 lakh interest deduction on a self-occupied house.
So the real question isn't just "what can I claim?" — it's "is the old regime, with these deductions, still cheaper for me than the new regime's lower slab rates without them?" For someone with a large interest outgo plus other 80C investments, the old regime often wins. For someone with a small loan and few deductions, the new regime's lower rates may save more. Run both before you file.
Note: the let-out-property interest set-off has historically had some treatment even under the new regime, but the rules are nuanced and change. Confirm the current year's position with a tax professional rather than assuming.
A quick illustration
Suppose, in a year, you pay around ₹2.4 lakh in interest and ₹1.1 lakh in principal on a self-occupied home, and you're in the 30% slab under the old regime:
- Interest under 24(b): capped at ₹2 lakh → saves roughly ₹60,000 in tax.
- Principal under 80C: ₹1.1 lakh (within the ₹1.5 lakh cap) → saves up to ₹33,000, if not already used by other 80C items.
- Combined: potentially ₹90,000+ in tax saved that year — but only under the old regime.
Numbers are illustrative; your actual benefit depends on your slab, your other deductions, and the regime you pick.
Joint home loans: double the limits
If you buy with a spouse or family member and both are co-owners and co-borrowers, each can claim the deductions separately on their share. That means a couple could together claim up to ₹3 lakh under 80C and ₹4 lakh under 24(b) — provided both contribute to the EMI and both opt for the old regime. It's one of the most effective ways to maximise home loan tax benefits.
How to maximise your home loan tax benefits
- Choose the right regime each year. It's not a permanent decision for most salaried taxpayers — re-evaluate annually.
- Don't double-count 80C. If PPF and EPF already use your ₹1.5 lakh, the principal adds nothing extra. Plan investments around that.
- Keep the interest component visible. Ask your lender for an annual provisional interest certificate — it's your proof at filing time.
- Model the loan before you borrow. A longer tenure means more interest (and more 24(b) headroom) but a higher total cost. Compare scenarios on our EMI calculator, and check our home loan options for current illustrative rates from ~8.5% p.a., subject to the lender.
- Weigh prepayment against deductions. Prepaying saves interest but also shrinks your future 24(b) claim. See how the maths plays out on the prepayment calculator.
- Mind your credit profile. A strong credit score of 750+ helps you secure a lower rate in the first place — the cheapest interest is interest you never pay.
Frequently asked questions
Can I claim home loan tax benefits under the new tax regime? Generally no — for a self-occupied property, the Section 80C principal deduction and the Section 24(b) interest deduction are available only under the old regime. The new regime offers lower slab rates instead of these deductions, so compare your total tax under both before filing.
Can I claim both Section 80C and Section 24(b) together? Yes, on the old regime. They apply to different parts of your EMI — 80C to the principal (up to ₹1.5 lakh) and 24(b) to the interest (up to ₹2 lakh for a self-occupied home) — so you can claim both in the same year.
Do both joint borrowers get separate tax benefits? Yes. If both are co-owners and co-borrowers and each repays a share of the loan, each can independently claim up to the 80C and 24(b) limits on their portion, effectively doubling the household's deductions — provided both are on the old regime.
