Section 24(b)
TaxHome Loan Interest Deduction under Section 24(b)
An income tax deduction on the interest paid on a home loan, up to ā¹2 lakh per year for self-occupied property. For let-out property, the full interest is deductible with no upper limit.
Definition
Section 24(b) of the Income Tax Act allows a deduction on the interest paid on a home loan, reducing the taxable income of property owners. It is one of the most valuable tax deductions available to home loan borrowers.
The deduction works differently based on how the property is used:
- Self-occupied property: Deduction limited to ā¹2 lakh per financial year on interest paid
- Let-out (rented) property: Full interest deductible with no upper cap
Section 24(b) is separate from Section 80C ā which covers the principal repayment. Together, they form the complete tax benefit framework for home loan borrowers under the old tax regime.
Formula
Interest component of EMI (from amortisation schedule):
Deduction = min(Actual Interest Paid, ā¹2,00,000) ā for self-occupied property
Deduction = Actual Interest Paid ā for let-out property (no cap)
In early years of a home loan, the interest component is large. Use the home loan EMI calculator or amortisation calculator to see the interest vs principal split for each year.
Worked Example
Vikram has a home loan of ā¹60,00,000 at 8.75% for 20 years. In the first year:
- Annual EMI payments ā ā¹6,36,000
- Interest component in Year 1 ā ā¹5,19,000
- Principal repaid in Year 1 ā ā¹1,17,000
Tax benefits (old regime):
- Section 24(b) deduction: min(ā¹5,19,000, ā¹2,00,000) = ā¹2,00,000
- Section 80C principal deduction: ā¹1,17,000
Total home loan tax deductions in Year 1 = ā¹3,17,000
At 30% tax slab, this saves ā ā¹99,000 in tax (including cess) ā nearly 2 months of EMI recovered as tax savings.
Key Things to Know
- Joint home loan ā double benefit: If a home loan is taken jointly (e.g., husband and wife, both co-owners), each co-borrower can claim up to ā¹2 lakh separately under Section 24(b) and up to ā¹1.5 lakh under Section 80C ā effectively doubling the household tax benefit to ā¹7 lakh per year.
- Possession mandatory: Section 24(b) deduction is available only after the property is ready for possession. For under-construction properties, interest during construction is accumulated as pre-construction interest and spread over 5 years from the year of possession.
- Second home: If you own a second property and it is declared as let-out (or deemed let-out), the full interest on that property's loan is deductible ā but any net loss from house property can only be set off against ā¹2 lakh of other income per year. The remaining loss is carried forward for 8 years.
- Amortisation schedule significance: The interest eligible for Section 24(b) changes every year ā it is highest in Year 1 and reduces as the loan amortises. Your bank's loan statement (or our amortisation calculator) shows the exact interest paid each financial year.
- Not available under new regime for self-occupied: This is a key reason many home loan borrowers with high interest outgo prefer the old tax regime ā the combined 80C + Section 24(b) benefit of up to ā¹3.5 lakh can outweigh the lower slab rates of the new regime.
