Section 24(b) provides a deduction on the interest paid on a home loan (housing loan) when computing income under the head “Income from House Property”.
It is one of the most popular provisions for taxpayers who have taken a loan to buy, build, repair, or reconstruct a house property.
Section 24(b) = Tax relief on home loan interest, making home ownership more affordable while reducing taxable income.
What Section 24(b) Covers?
1. Self-Occupied Property (SOP)
- Deduction of interest paid on home loans, up to ₹2 lakh p.a., if:
- Loan was taken on or after April 1, 1999
- For purchase or construction
- Completed within five years from end of loan year
— Otherwise, deduction is capped at ₹30,000.
- Two self-occupied properties can be claimed since AY 2020-21, but the aggregate interest limit remains the same.
2. Let-Out (Rented) or Deemed Let-Out Property
- No upper limit on interest deduction—full interest is deductible.
Points to be noted:
- If interest is paid before construction is completed, it can be claimed in 5 equal installments, starting from the year construction is completed.
- If property is co-owned and loan is in joint names, each co-owner can claim deduction separately (subject to limits)
Example:
Mr. A buys a house on loan.
- Annual Interest on Loan = ₹2,40,000
Case 1: Property is self-occupied
👉 Deduction allowed u/s 24(b) = ₹2,00,000 (cap applies).
Case 2: If the same property was let-out,
👉 Deduction allowed u/s 24(b) = full ₹2,40,000 would be deductible.
Regime Matters for Home Loan Deductions: Old vs. New Tax Regime
| Regime | Section 24(b) Deduction |
| Old (classic) Regime | Available for SOP (₹2 lakh limit) and full interest for let-out. |
| New (default) Regime | SOP deduction not available; full deduction still allowed for let-out properties. |

👉 Practical takeaway:
- Loan must be for property purchase/construction/renovation.
- Completion certificate required.

- Refinance loans also eligible.
- Joint borrowers: claim in proportion to repayment.
- Self-occupied capped at ₹2 lakh; let-out = full interest.
Smart Planning & Strategy Tips
1. Choose the Right Regime
- Opt for the old regime if you’re claiming SOP interest deduction.
- Stick with the new regime only if deductions aren’t worth the lower slab rates.
2. Leverage Pre-construction Interest
Even if construction spans multiple years, you can claim interest in five equal installments after completion—now clarified for rental properties too .
3. Maximize Joint Borrower Benefits
Co-borrowers (who are also co-owners) each get separate interest deductions—i.e., up to ₹2 lakh each—for joint loans.
4. Watch for Let-Out Calculation
If your property was rented part-year and self-occupied part-year, it’s treated as fully let-out for calculation—important when using rental income vs. borrowing.
5. Maintain Supporting Docs
Maintain below documents:
- Interest certificate from lender
- Loan sanction letter
- Repayment schedule
- Construction completion certificate (for pre-prod cases)
—These are crucial for audits or scrutiny.
