What Is Section 24(b)?
Section 24(b) of the Indian Income Tax Act allows homeowners to claim a tax deduction for interest paid on housing loans taken for purchasing, constructing, repairing, renewing, or reconstructing residential property. Subject to specific conditions and tax regimes, Section 24(b) reduces your taxable income, lowering your overall income tax liability.
Indicative Section 24(b) Deduction Limits
Section 24(b) tax treatment varies based on Property Type (Self-Occupied vs. Let-Out), Loan Purpose (Purchase/Construction vs. Repair), and Tax Regime (Old vs. New Regime):
| Scenario & Parameters | Indicative Deduction Limit | House Property Loss & Set-Off Treatment |
|---|---|---|
| Self-Occupied + Purchase / Construction (Old Regime) | Up to ₹2,00,000 / year | Loss of up to ₹2 Lakh can be set off against salary and other income heads. |
| Self-Occupied + Repair / Renovation (Old Regime) | Up to ₹30,000 / year | Loss of up to ₹30,000 can be set off against salary and other income. |
| Let-Out / Rented Property (Old Regime) | Actual eligible interest (No cap) | House property loss set-off against other income heads capped at ₹2 Lakh/year; excess carried forward up to 8 years. |
| Self-Occupied Property (New Tax Regime) | ₹0 (Disallowed) | No interest deduction or loss set-off allowed under the New Tax Regime for self-occupied properties. |
| Let-Out / Rented Property (New Tax Regime) | Actual eligible interest against rent | Interest deductible only against rental income; house property loss cannot be set off against salary/other heads. |
Tax Deduction vs. Actual Tax Saving
It is crucial not to confuse a Tax Deduction with Actual Tax Savings:
- Tax Deduction (e.g. ₹2,00,000): This is the eligible interest amount subtracted from your taxable income. It does not mean a ₹2,00,000 cash refund from the tax authority.
- Actual Tax Saving: Your actual cash tax relief equals the eligible interest deduction multiplied by your marginal tax slab rate. At a 30% tax slab, a ₹2,00,000 deduction reduces your cash tax outgo by
₹2,00,000 × 30% = ₹60,000(plus cess).
Interest Paid vs. Eligible Interest
Paying ₹3,50,000 in annual home-loan interest does not mean the entire ₹3.5 Lakh is deductible. For a self-occupied property under the Old Tax Regime:
- Annual Interest Paid: ₹3,50,000
- Section 24(b) Statutory Cap: ₹2,00,000
- Eligible Section 24(b) Interest:
MIN(₹3,50,000, ₹2,00,000) = ₹2,00,000 - Non-Eligible Interest (Above Cap):
₹3,50,000 − ₹2,00,000 = ₹1,50,000
Section 24(b) Document Checklist for Tax Filing
Obtain the provisional/final interest certificate from your lending bank showing exact principal and interest split.
Keep possession letter or completion certificate ready (construction must complete within 5 years for ₹2L limit).
Retain your loan agreement showing loan purpose (purchase, construction, or renovation) and sanction date.
If co-borrowing, keep property deed and co-applicant agreement to establish respective ownership & interest share.
Maintain rent agreements, municipal tax receipts, and tenant bank receipts if claiming let-out interest deductions.
If loan was taken before completion, track pre-construction interest (claimable in 5 equal annual installments).
Frequently Asked Questions
Can both husband and wife claim ₹2 Lakh Section 24(b) interest deduction on a joint home loan?
Yes. If both spouses are joint owners of the house property and co-borrowers paying EMIs from their respective bank accounts, each spouse can individually claim up to ₹2,00,000 under Section 24(b) (total ₹4,00,000 per family) under the Old Tax Regime, subject to their actual interest payment share.
What is pre-construction interest under Section 24(b)?
Interest paid during the period prior to the financial year in which property construction or acquisition is completed is termed pre-construction interest. It can be claimed as a deduction in 5 equal annual installments starting from the year construction is completed, within the overall ₹2 Lakh annual limit for self-occupied properties.
Why is Section 24(b) interest deduction ₹0 under the New Tax Regime for self-occupied homes?
Under Section 115BAC (New Tax Regime), statutory interest deductions for self-occupied properties under Section 24(b) are dis-allowed in exchange for lower concessional tax slab rates.
