What is Section 24 Deduction: Save Tax on Home Loan Interest

Section 24 of the Income Tax Act lets homeowners deduct up to ₹2 lakh on home loan interest. Learn who qualifies, how much you save and how rental property is taxed with real examples.
Quick Summary (TL; DR)
Section 24 of the Income Tax Act says you can get a deduction on the interest you pay on a home loan. If you live in the house yourself you can get up to ₹2 lakh per year as a deduction.
But if you have rented it out you can claim the interest paid there is no limit on that. This deduction is only available if you choose the tax regime. The rule applies to both houses you live in and houses you rent out.
What Is Section 24 of the Income Tax Act?
When you buy a house using a loan you have to pay two things every month. You pay the principal and the interest. Section 80C is useful for the principal. Section 24 is useful for the interest. Section 24 is part of the income from house property. This means you can subtract the interest you pay on your house loan from the income that's taxable. This will directly lower the tax that you owe.
There are two kinds of deductions that you can get under Section 24.
Standard Deduction is thirty percent of the income. This is for houses that you let someone else use.
Interest on a house loan is the deduction. You can get a deduction of up to ₹2 lakh for a house that you use yourself. If you let someone else use the house then there is no statutory cap on interest deduction for a let-out property under Section 24(b). However,the taxpayer cannot adjust more than ₹2 lakh of house property loss against other income in one financial year. The remaining loss is carried forward for 8 years.
What Is Income from House Property?
For tax purposes, the government treats every property you own as a source of income - even if it’s your own home. They call this “Income from House Property,” and it’s one of five main kinds of income on your tax return.
Here is how it works for each type of property:
Property Type | How It Is Taxed |
Self-Occupied (you live in it) | Annual value is taken as Nil. No rental income assumed. |
Let-Out (given on rent) | Actual rent received is your income. Deductions apply. |
Deemed Let-Out (second home, vacant) | Notional rent is assumed as income and taxed. |
If you own more than one house, you can pick one to call your primary residence. The rest? Tax authorities just assume you’ve rented those out, even if they sit empty. So, you get taxed on the rent you could have earned, not just actual rent you collect.
Section 24 Deduction: Self-Occupied Property
This is the most common situation. You bought a home, took a loan and you live there.
Maximum deduction under Section 24 for self-occupied property: ₹2,00,000 per year on home loan interest.
But to claim the full ₹2 lakh, these conditions must be met:
The loan must be taken for buying or constructing the property - not renovation.
The loan must have been taken on or after 1st April 1999.
Construction must be completed within 5 years of taking the loan.
If construction takes more than 5 years, the deduction limit drops to just ₹30,000 - not ₹2 lakh. This is why delays in under-construction projects can cost you lakhs in lost deductions.
Real Example: Priya's Self-Occupied Flat in Bengaluru
Priya bought a flat for ₹80 lakh and took a home loan of ₹60 lakh at 8.5% interest.
Detail | Amount |
Home Loan Amount | ₹60,00,000 |
Annual Interest Paid (Year 1) | ₹4,98,000 (approx.) |
Maximum Deduction Allowed (Sec 24) | ₹2,00,000 |
Tax Saved (30% bracket) | ₹60,000 |
Remaining Interest (not deductible) | ₹2,98,000 |
Priya pays nearly ₹5 lakh in interest but can only claim ₹2 lakh. Still, she saves ₹60,000 in taxes every year. Over 5 years, that is ₹3 lakh saved.
Section 24 Deduction: Let-Out Property
If you’re renting out your property, the rules actually get a bit better for you. There’s no limit on how much loan interest you can claim as a deduction under Section 24 you can use the full amount you’ve paid. Of course, you do need to show the rent you’ve earned as income.
Step | Calculation |
Gross Annual Rent | ₹3,00,000 (₹25,000/month) |
Less: Municipal Tax Paid | ₹12,000 |
Net Annual Value (NAV) | ₹2,88,000 |
Less: 30% Standard Deduction (Sec 24a) | ₹86,400 |
Less: Home Loan Interest (Sec 24b) | ₹4,00,000 |
Income from House Property | -₹1,98,400 (Loss) |
This is how it turns out: Sometimes your deductions will be bigger than what you actually earn from rent. That means you end up with a loss from house property. You can use this loss to reduce your taxable salary income, up to ₹2 lakh each year. If there’s still some loss left after that, just carry it forward for up to 8 years.
What Is the 30% Standard Deduction Under Section 24?
Section 24(a) allows you to automatically deduct 30% of the Net Annual Value (NAV) from your let-out property for repairs and upkeep no questions asked, no paperwork needed.
You don’t have to collect bills or worry about receipts. Every landlord with a rented property gets this flat deduction.
But if you’re living in the property yourself, you don’t get this benefit, since the annual value is considered zero anyway.
Can You Claim Pre-Construction Interest?
You’ve already started paying EMIs, but the place isn’t ready yet. The money you pay as interest during this construction phase is known as pre-construction interest. You can’t claim this interest as a deduction while the building is still going up.
But here’s the good part - once the flat is finished, you can claim that total pre-construction interest in five equal parts over five years, starting from the year the construction wraps up.
Year | Pre-Construction Interest Claimable |
Year of completion + 1 | 1/5th of total pre-construction interest |
Year of completion + 2 | 1/5th of total pre-construction interest |
Year of completion + 3 | 1/5th of total pre-construction interest |
Year of completion + 4 | 1/5th of total pre-construction interest |
Year of completion + 5 | 1/5th of total pre-construction interest |
This 1/5th amount is added to your regular annual interest and claimed together subject to the overall ₹2 lakh cap for self-occupied property.
What Is the Difference between Section 24 vs Section 80C?
Feature | Section 80C | Section 24 |
What it covers | Principal repayment, stamp duty, registration | Interest on home loan |
Limit | ₹1.5 lakh (combined all 80C) | ₹2 lakh (self-occupied), unlimited (let-out) |
Property type | Residential only | Residential (self-occ. or let-out) |
Tax regime | Old regime only | Old regime only |
Applicable from | Year of payment | Year of accrual |
Together, Sections 80C and 24 can give a homebuyer up to ₹3.5 lakh in annual deductions ₹1.5 lakh on principal and ₹2 lakh on interest. At the 30% tax bracket, that is a saving of up to ₹1,05,000 every year.
Old Tax Regime vs New Tax Regime
Section 24 deductions are available only under the old tax regime. The new tax regime offers lower slab rates but removes most deductions, including home loan interest.
Benefit | Old Regime | New Regime |
Section 24 (Home Loan Interest) | Up to ₹2 lakh | Not available |
Section 80C (Principal + Stamp Duty) | Up to ₹1.5 lakh | Not available |
Standard Deduction (Salary) | ₹50,000 | ₹75,000 (from FY 2024-25) |
Who benefits more | High loan, high deductions | Low deductions, simpler filing |
If you have a large home loan, the old regime is almost always better. Run both calculations before filing or ask a CA to do it for you.
