A home loan is one of the few financial products in India that generates income tax deductions on both the principal repayment and the interest payment — simultaneously, every year, for the entire tenure of the loan. A salaried individual in the 30% tax bracket with a ₹60 lakh home loan at 8.75% can reduce their annual tax outgo by ₹75,000-₹1,05,000 through Section 24(b) and Section 80C deductions alone. Over a 20-year loan tenure, the cumulative tax saving is significant enough to materially change the total cost of the borrowing.
But these deductions come with conditions — on the property (self-occupied vs let-out), on the tax regime (old vs new), on the stage of the loan (pre-possession interest is treated differently), and on joint ownership structure. Getting any one of these conditions wrong means leaving a deduction on the table or, worse, claiming one that is not available and facing a tax demand.
| Home loan tax deductions available under the old tax regime: Section 24(b) — up to ₹2 lakh/year on interest for self-occupied property (no limit for let-out property). Section 80C — up to ₹1.5 lakh/year on principal repayment (within overall 80C limit). Joint borrowers can each claim — effectively doubling the benefit. New tax regime: Section 24(b) for self-occupied property NOT available. Only let-out property interest deductible (subject to conditions).

Section 24(b) — The Interest Deduction
Section 24(b) of the Income Tax Act allows a deduction on the interest paid on a home loan. The amount and conditions depend on whether the property is self-occupied or let-out:
| Property Status | Old Tax Regime | New Tax Regime |
|---|---|---|
| Self-occupied | Up to ₹2 lakh/year deduction on interest paid | NOT available |
| Let-out (rented) | Full interest deductible (no upper limit), subject to set-off cap of ₹2L against other income | Full interest deductible against rental income (no cap) — loss cannot be set off against other income |
| Under-construction (pre-possession) | Deductible in 5 equal instalments starting from possession year, in addition to that year’s deduction | Not available for self-occupied; applies for let-out |

| SECTION 24(b): HOW THE ₹2 LAKH LIMIT WORKS IN PRACTICE On a ₹60 lakh loan at 8.75%, Year 1 interest ≈ ₹5.1 lakh → You can claim only ₹2 lakh of this under Section 24(b) for a self-occupied property. The remaining ₹3.1 lakh is not deductible. The ₹2 lakh cap is per taxpayer, per year, for a self-occupied property. If you have two home loans, the cap of ₹2 lakh applies to the total across all self-occupied properties. On a ₹30 lakh loan at 8.75%, Year 5 interest ≈ ₹2.1 lakh → As you progress through the loan tenure, the interest component of each EMI falls (because outstanding principal reduces). Within 7-10 years on a ₹30 lakh loan, annual interest may fall below ₹2 lakh — meaning you are claiming the full interest amount. The ₹2 lakh cap typically binds most aggressively in the early years of a large loan. Let-out property — no limit → If the property is rented out, the full interest amount is deductible against rental income under Section 24(b). If interest exceeds rental income, the loss (up to ₹2L) can be set off against salary income under the old regime. Under the new regime, the loss cannot be set off against salary — it can only be carried forward. |
Section 80C — The Principal Repayment Deduction
The principal component of each EMI paid on a home loan is deductible under Section 80C, up to ₹1.5 lakh per year. This is within the overall Section 80C limit of ₹1.5 lakh — which also includes EPF contributions, LIC premiums, PPF, ELSS, and other qualifying investments.
| Critical point: If you are already utilising the full ₹1.5 lakh Section 80C limit through EPF, LIC, and PPF contributions — which most salaried employees are — your home loan principal repayment does not generate any additional deduction. The 80C bucket is shared. You must check your existing 80C utilisation before assuming the home loan principal adds a new benefit. Source: ClearTax India; Income Tax Act 1961 Section 80C. |
Section 80C also allows you to deduct stamp duty and property registration charges paid in the year of purchase — as a one-time deduction, also within the ₹1.5 lakh overall limit. This is particularly useful for first-time buyers in the year of purchase, when principal repayment is still small.
Joint Home Loan — Doubling the Tax Benefit
If a home loan is taken jointly — with a spouse, parent, or sibling as co-borrower — and the co-borrower is also co-owner of the property, each borrower can independently claim the Section 24(b) and Section 80C deductions. This means a married couple who are both co-borrowers and co-owners can claim up to ₹4 lakh combined on interest (₹2L each) and up to ₹3 lakh combined on principal (₹1.5L each), totalling ₹7 lakh in annual deductions — approximately double the individual limit.
| Scenario | Max Annual Deduction | Tax Saving (30% bracket) |
|---|---|---|
| Single borrower, old regime, self-occupied | ₹2L (interest) + ₹1.5L (principal) = ₹3.5L | ~₹1.05L/year |
| Joint borrowers (both co-owners), old regime | ₹4L (₹2L each) + ₹3L (₹1.5L each) = ₹7L combined | ~₹2.1L/year combined |
| Single borrower, new regime, self-occupied | ₹0 (no Section 24 or 80C for self-occupied) | ₹0 |
| Single borrower, old regime, let-out property | Full interest (no cap) + ₹1.5L principal | Depends on interest amount and rental income |

The Old Regime vs New Regime Decision for Home Loan Borrowers
This is the single most important tax decision for a home loan borrower. The new income tax regime, which became the default from FY 2023-24, offers lower slab rates but eliminates most deductions — including Section 24(b) for self-occupied property and Section 80C for principal repayment. If you are on the new regime, your home loan provides zero tax benefit on a self-occupied property.
For most home loan borrowers with significant interest outgo (i.e., loan above ₹25 lakh at current rates), the old regime is more tax-efficient — because the Section 24(b) + 80C deductions outweigh the rate advantage of the new regime. But the crossover point depends on your total deductions. A qualified Chartered Accountant can calculate this in 15 minutes. It is one of the most high-return conversations available to a home buyer.

Sirf Broker POV
The home loan tax benefit is one of the most frequently cited reasons people give for buying property in India — and one of the most poorly understood in practice. The gap between “my home loan saves me tax” and “I know exactly how much tax my home loan saves me, and I’ve verified that I’m on the right tax regime to claim it” is enormous in the average buyer’s understanding.
The broker who can explain — even at a high level — that the Section 24(b) deduction is only available under the old regime, that the ₹2 lakh cap applies per taxpayer and not per property, and that joint co-borrowing doubles the available benefit, is giving advisory value that goes well beyond showing property. These are not complex concepts. They require 10 minutes of explanation and a basic knowledge of the Income Tax Act sections. Most buyers haven’t heard them from their broker, their bank relationship manager, or their builder’s sales team.
We are not suggesting brokers become tax advisors. Always refer buyers to a CA for specific calculations. But knowing the framework — and being able to explain why a buyer on the new regime gets zero property-linked tax deduction, or why adding the spouse as a co-borrower and co-owner doubles the available saving — is the difference between an advisor and a transaction facilitator.
Conclusion
A home loan generates up to ₹3.5 lakh per year in income tax deductions for a single borrower under the old tax regime: ₹2 lakh on interest under Section 24(b) and ₹1.5 lakh on principal repayment under Section 80C. Joint co-borrowers who are also co-owners can double this to ₹7 lakh combined. The new income tax regime eliminates Section 24(b) and Section 80C deductions for self-occupied property entirely. The most important tax decision for a home loan borrower is not which property to buy — it is which tax regime to be on. Calculate this with a CA before filing your return, not after.
Frequently Asked Questions
1. What is Section 24(b) and what does it allow me to deduct?
Section 24(b) of the Income Tax Act allows you to deduct the interest paid on a home loan. For a self-occupied property under the old tax regime, the maximum deduction is ₹2 lakh per year. For a let-out property, the full interest is deductible against rental income with no upper limit. This deduction is not available at all under the new income tax regime for self-occupied property.
2. Can I claim home loan deductions under the new income tax regime?
Only partially. Section 24(b) for self-occupied property is NOT available under the new regime. Section 80C for principal repayment is also not available. If your property is rented out, interest on the home loan is deductible against rental income even under the new regime — but the loss cannot be set off against salary income. The old regime is generally more beneficial for home loan borrowers.
3. What is the maximum tax deduction on a home loan per year in India?
Under the old tax regime: ₹2 lakh on interest (Section 24b) + up to ₹1.5 lakh on principal (Section 80C) = ₹3.5 lakh maximum per borrower per year. Joint co-borrowers who are also co-owners can each claim independently — maximum ₹7 lakh combined annually. At the 30% tax bracket, ₹3.5 lakh of deductions saves approximately ₹1.05 lakh in tax.
4. Can I claim Section 80C on home loan principal if I already max out my 80C with PF and LIC?
No. The ₹1.5 lakh Section 80C limit is shared across all qualifying investments — EPF, LIC, PPF, ELSS, NSC, and home loan principal repayment. If you are already utilising ₹1.5 lakh through EPF and LIC premiums, your home loan principal does not generate any additional deduction. Check your existing 80C utilisation before assuming the home loan adds a new benefit.
5. Can both spouses claim home loan tax deductions?
Yes — if both are co-borrowers AND co-owners of the property, each can independently claim Section 24(b) (up to ₹2L each) and Section 80C (up to ₹1.5L each). This requires the property to be registered in both names and the EMI to be paid from accounts associated with both borrowers. Combined maximum deduction: ₹7 lakh per year.
6. Can I claim tax deduction on a home loan for a property under construction?
Section 24(b) deduction on interest is not available until the year of possession. Pre-possession interest — the interest paid on the loan before you receive the property — can be claimed in 5 equal annual instalments starting from the year of possession, in addition to that year’s normal interest deduction. Under the new tax regime, this is not available for self-occupied property.
