Section 24b: Home Loan Interest Deduction Explained
A ₹2 lakh deduction on home loan interest sounds straightforward — until you check whether your property actually qualifies.
If you have a home loan in India, Section 24(b) of the Income Tax Act is one of the most valuable deductions available to you — but only under the old tax regime. It allows you to reduce your taxable income by the interest you pay on a loan taken to purchase, construct, repair, or reconstruct a residential property. Understanding the exact rules prevents you from overclaiming or missing out.
The Two Types of Property Under Section 24b
Your deduction limit depends entirely on whether the property is self-occupied or let out:
| Property Type | Maximum Deduction |
|---|---|
| Self-occupied (you live in it) | ₹2,00,000 per year |
| Let-out (rented to someone else) | No upper limit (entire interest deductible) |
| Deemed let-out (3rd+ property) | No upper limit |
For a self-occupied property, the ₹2 lakh cap applies per year, per taxpayer. If you and your spouse are co-borrowers and both file taxes separately, each can claim up to ₹2 lakh — effectively doubling the benefit.
Pre-Construction Interest
What if your property was under construction when you took the loan? You cannot claim interest during the pre-construction period in real time, but you are not completely shut out. The total interest paid from loan disbursement to 31 March of the year before possession is treated as pre-construction interest. This amount is deductible in five equal annual instalments starting from the year of possession.
Loan taken : April 2022
Possession : March 2026
Pre-construction interest paid (3 years): ₹3,60,000
Annual deduction for pre-construction interest:
₹3,60,000 ÷ 5 = ₹72,000 per year
Combined with post-possession interest of ₹1,40,000:
Total Section 24b claim = ₹72,000 + ₹1,40,000 = ₹2,12,000
→ Capped at ₹2,00,000 for self-occupied property
Conditions for Claiming the Full ₹2 Lakh
The higher ₹2 lakh limit applies only if both conditions are met:
- The loan was taken on or after 1 April 1999.
- Construction is completed within 5 years from the end of the financial year in which the loan was taken.
If construction takes longer than 5 years, the deduction is capped at only ₹30,000 per year. This is a critical condition that borrowers often overlook on delayed projects.
Section 24b Under the New vs Old Tax Regime
This is the single biggest decision point:
- Old tax regime: Full Section 24b deduction up to ₹2 lakh available for self-occupied property. Losses from house property (when interest exceeds rental income) can be set off against salary income up to ₹2 lakh.
- New tax regime: Section 24b deduction is not available for self-occupied property. For let-out property, interest is deductible but the resulting loss cannot be set off against other income heads.

Section 80EE and 80EEA: Additional Deductions
Two additional deductions layer on top of Section 24b for eligible first-time homebuyers:
- Section 80EE (now largely expired): ₹50,000 extra deduction for loans sanctioned between 1 April 2016 and 31 March 2017.
- Section 80EEA: ₹1.5 lakh extra deduction for loans sanctioned between 1 April 2019 and 31 March 2022, where stamp duty value of property did not exceed ₹45 lakh.
These are only available under the old regime. If you have an eligible loan, your effective annual interest deduction could be ₹2,00,000 + ₹1,50,000 = ₹3,50,000.
What Documents Do You Need?
- Interest certificate from your bank or NBFC (SBI, HDFC, LIC Housing Finance, etc.) showing the split between principal and interest paid during the year.
- Possession certificate or completion certificate if claiming for a newly constructed property.
- Loan sanction letter if claiming 80EEA (to prove sanction date).
Practical Example
Rohan (income ₹15 lakh, old regime) pays ₹1,80,000 as home loan interest and ₹1,20,000 as principal on a self-occupied flat in Pune.
Gross salary income : ₹15,00,000
Standard deduction : ₹50,000
Net salary : ₹14,50,000
Section 24b interest deduction: ₹1,80,000
Income from House Property : -₹1,80,000 (loss)
Loss set-off against salary : ₹1,80,000
Taxable income : ₹12,70,000
Section 80C (principal + other): ₹1,50,000
Final taxable income : ₹11,20,000
Without Section 24b, Rohan's taxable income would have been ₹13,00,000. The deduction saves him approximately ₹37,440 in tax (at 20% slab + cess).
Conclusion
Section 24b is one of the few deductions that directly reduces your taxable income rather than offering a tax credit. For anyone in the 20% or 30% slab with a home loan on a self-occupied property, claiming the full ₹2 lakh deduction can save ₹41,600 to ₹62,400 annually. The critical steps are staying in the old regime, obtaining your interest certificate, and ensuring your construction timeline met the 5-year condition.

Frequently asked questions
Can I claim Section 24b under the new tax regime?+
For self-occupied property, the Section 24b deduction is not available under the new tax regime. For let-out property, interest is deductible but the resulting loss cannot be set off against other income. Most borrowers with a high home loan will find the old regime more beneficial.
What is the maximum deduction under Section 24b for a self-occupied house?+
₹2,00,000 per financial year, provided the loan was taken after 1 April 1999 and construction was completed within 5 years. If construction takes longer, the limit drops to ₹30,000.
Can both husband and wife claim Section 24b on the same home loan?+
Yes, if both are co-borrowers and co-owners of the property. Each can independently claim Section 24b deduction in proportion to their share of the loan repayment, up to ₹2 lakh each — giving a combined family saving of up to ₹4 lakh in taxable income.
How is pre-construction interest treated under Section 24b?+
Pre-construction interest (interest paid before the property is completed/acquired) is not deductible in real time. It is aggregated and then claimed in five equal annual instalments starting from the year of possession, subject to the overall ₹2 lakh cap for self-occupied property.
Is the principal repayment of a home loan also deductible?+
Yes, but under a different section. Principal repayment is deductible under Section 80C (up to ₹1.5 lakh overall limit), not under Section 24b. Section 24b covers only the interest component.
