Home Loan Tax Benefits: Section 80C and 24(b) Explained
Your Home Loan Is Also a Tax-Saving Tool
Most people think of a home loan only as a financial burden — decades of EMIs, interest payments, and a locked-up asset. But here is the part many borrowers miss: a home loan is one of the few financial products that gives you tax deductions on two separate fronts simultaneously.
Under the Old Tax Regime, you can claim deductions on both the principal you repay and the interest you pay, under two different sections of the Income Tax Act. In total, that is up to ₹3.5 lakh in deductions every year.
For a borrower in the 30% tax bracket, this translates to a potential tax saving of up to ₹1,05,000 per year — every year for the life of the loan.
1. The Two Key Deductions at a Glance
Home loan tax benefits come from two separate sections of the Income Tax Act. They work independently and can be claimed together:
Section 80C — Principal Repayment
Up to ₹1.5 Lakh/year
Covers the principal component of your home loan EMI. This ₹1.5 lakh limit is shared with other 80C investments like PPF, ELSS, insurance premiums, and NSC.
Property type: Both self-occupied and let-out.
Old Tax Regime Only
Section 24(b) — Interest Deduction
Up to ₹2 Lakh/year
Covers the interest component of your EMI. For self-occupied property, capped at ₹2 lakh. For let-out property, the full interest is deductible (with a set-off cap of ₹2 lakh/year on losses).
Condition: Construction must complete within 5 years of loan disbursal.
Old Tax Regime Only
Together, these two sections allow a maximum of ₹3.5 lakh in annual deductions on a self-occupied home loan under the Old Tax Regime.
2. Section 80C — Principal Repayment Deduction
Under Section 80C, the principal portion of your home loan EMI qualifies for a tax deduction, up to a combined limit of ₹1.5 lakh per financial year. This limit is shared with a wide range of other investments and expenses.
What counts under 80C?
Principal portion of your home loan EMI
Stamp duty and registration charges paid at purchase (claimable in the year of payment only)
PPF contributions, ELSS mutual fund investments, NSC, tax-saving FDs
Life insurance premiums, NPS contributions (Tier I), tuition fees for children
The Hidden Reality: Early EMIs Have Very Little Principal
In the first year of a ₹50 lakh home loan at 8.5% for 20 years, your monthly EMI is ₹43,391. But only about ₹7,974 of that goes toward principal — the rest (₹35,417) is interest. So in year 1, the total principal repaid is roughly ₹96,000 — well below the ₹1.5 lakh 80C limit. Most borrowers supplement this with PPF or ELSS to fully utilise Section 80C.
One Important Lock-in Condition
If you sell the property within 5 years of possession, all the 80C deductions you claimed on principal repayment will be added back to your income in the year of sale and taxed accordingly. This is a common trap that many borrowers walk into when they sell early for a profit.
3. Section 24(b) — Interest Deduction (The Bigger Benefit)
Section 24(b) allows you to deduct the interest paid on your home loan from your taxable income. For most borrowers, especially in the first decade of the loan, this is the more valuable of the two deductions because interest forms the largest portion of early EMIs.
For Self-Occupied Property
Maximum deduction: ₹2 lakh per financial year
The loan must have been taken for purchase or construction of the property
If taken for renovation or repair: limit is ₹30,000 (not ₹2 lakh)
Construction must complete within 5 years from the end of the financial year in which the loan was taken — otherwise, the limit drops to ₹30,000
For Let-Out (Rented) Property
The full interest paid is deductible — no ₹2 lakh cap on the deduction
However, if this creates a net loss from house property, you can set off only up to ₹2 lakh per year against other income (salary, business, etc.)
Any remaining loss (beyond ₹2 lakh) is carried forward for up to 8 assessment years
Pre-Construction Interest
If your loan was disbursed before construction was completed (common with under-construction properties), you can claim the interest paid during the pre-construction period. This is done in 5 equal annual instalments starting from the financial year in which construction is completed, subject to the ₹2 lakh overall cap. So if you paid ₹3 lakh in pre-EMI interest before possession, you can claim ₹60,000 per year for 5 years.
4. Practical Example — How Much Do You Actually Save?
Let us take a concrete example. You have a home loan of ₹50 lakh at 8.5% for 20 years. Monthly EMI: ₹43,391. You are in the 30% tax bracket and opted for the Old Tax Regime.
Tax Saving Calculation — Year 1 of Loan
Total EMI paid in Year 1₹5,20,692
Interest component (Year 1)₹4,24,869
Principal component (Year 1)₹95,823
Section 24(b) deduction (capped at ₹2L)₹2,00,000
Section 80C deduction (principal repaid)₹95,823
Total deduction claimed₹2,95,823
Tax saved at 30% bracket (+ 4% cess)₹92,290
In year 1, even though the interest alone was over ₹4.2 lakh, the Section 24(b) cap limits the deduction to ₹2 lakh. As the loan ages and the principal portion of EMIs grows, the 80C benefit grows slightly too — but the combined saving consistently stays in the range of ₹80,000–1,05,000 per year for a 30% taxpayer in the first 8–10 years of the loan.

5. Old Tax Regime vs New Tax Regime — Which Is Better for Home Loan Borrowers?
From FY 2024–25, the New Tax Regime is the default for all salaried employees unless you explicitly opt for the Old Tax Regime each year. The two regimes treat home loan deductions very differently:
Deduction
Old Tax Regime
New Tax Regime
Section 80C (Principal repayment)
✓ Allowed (up to ₹1.5L)
✗ Not allowed
Section 24(b) — Self-occupied
✓ Allowed (up to ₹2L)
✗ Not allowed
Section 24(b) — Let-out property
✓ Full interest deductible
✓ Allowed (with conditions)
Standard deduction (salaried)
✓ ₹50,000
✓ ₹75,000 (from FY 2024–25)
HRA exemption
✓ Allowed
✗ Not allowed
Tax slabs
Old slabs (higher rates)
New slabs (lower rates)
Always compare total tax liability under both regimes with a tax calculator or CA before choosing. The right answer depends on your income, other deductions, and loan size.
When the Old Regime Usually Wins for Home Loan Borrowers
If your annual income is ₹15 lakh or more, you have a large home loan (₹40 lakh+), and you are claiming Section 24(b) in full (₹2 lakh) plus other deductions like HRA, 80D (health insurance), and 80C investments — the Old Tax Regime typically saves more tax overall. At incomes below ₹10–12 lakh, the New Regime's lower base rates often win even without deductions.
6. Common Mistakes Borrowers Make
Defaulting to the New Regime without comparing: Many salaried employees auto-default to the New Regime and miss out on ₹80,000–1,00,000 in annual tax savings from their home loan. Always do the math.
Claiming interest on under-construction property: You cannot claim Section 24(b) deduction during the construction period. The deduction starts only from the year of possession (pre-construction interest is claimed in 5 instalments post-possession).
Forgetting stamp duty under 80C: Stamp duty and registration costs paid at purchase are eligible for 80C deduction in that financial year. Most borrowers overlook this one-time benefit.
Assuming the full interest is deductible: For self-occupied property, only ₹2 lakh of interest per year is deductible under 24(b), regardless of how much you actually paid. On a ₹50L loan at 8.5%, you pay over ₹4.2 lakh in interest in year 1 — but can only claim ₹2 lakh.
Selling within 5 years of possession: This reverses all 80C deductions claimed and adds them back to your taxable income in the year of sale.

Use our free EMI Calculator to see exactly how much of each EMI goes toward interest vs principal — so you know precisely what to claim under each section.
Under the Old Tax Regime, you can claim up to ₹1.5 lakh per year on principal repayment (Section 80C) and up to ₹2 lakh per year on interest paid (Section 24(b)) for a self-occupied property. This totals ₹3.5 lakh in deductions. If you are in the 30% tax bracket, the maximum annual tax saving is approximately ₹1,05,000 (including cess). If you are in the 20% bracket, the saving is approximately ₹70,000 per year.
Yes. Both deductions are available simultaneously on the same home loan under the Old Tax Regime. Section 80C covers the principal repayment component of your EMI (up to ₹1.5 lakh, shared with other 80C investments), while Section 24(b) covers the interest component (up to ₹2 lakh for self-occupied property). They are separate sections with separate limits and can be claimed together.
For a self-occupied property, no. The New Tax Regime (which is the default from FY 2024–25) does not allow the Section 80C deduction on principal repayment or the Section 24(b) deduction on interest. If maximising home loan tax benefits matters to you, you may want to opt for the Old Tax Regime. Always compare total tax payable under both regimes using a tax calculator or with a chartered accountant before deciding.
For a let-out (rented) property, there is no upper limit on the interest deduction under Section 24(b) in the Old Tax Regime — you can claim the full interest paid. However, if the deduction creates a loss from house property, the amount you can set off against other income (like salary) in the same year is capped at ₹2 lakh. Any remaining loss can be carried forward for up to 8 assessment years.
Section 80C applies only to the principal repayment component of your EMI — not the interest. Every EMI has two parts: an interest component (claimed under Section 24(b)) and a principal repayment component (claimed under Section 80C). In the early years of a home loan, the principal portion is very small — as little as 15–18% of the EMI. Most borrowers supplement this with PPF, ELSS, or insurance premiums to fully utilise the ₹1.5 lakh 80C limit.
