Understanding Section 24(b): Home Loan Interest Deductions
- How the ₹2,00,000 deduction cap applies strictly to self-occupied homes under the Old Regime.
- Why Section 24(b) relief on self-occupied properties is completely disallowed under the New Tax Regime.
- The five-instalment rule for claiming pre-construction interest after taking physical possession.
Every year around PCDA and PAO tax declaration deadlines, personnel ask whether prepaying a housing loan destroys their tax advantage under Section 24(b). The math behind Section 24(b) of the Income-tax Act, 1961 is straightforward, but people regularly misunderstand how the deduction interacts with tax regimes and property status. Under the Old Tax Regime, you can deduct up to ₹2,00,000 in interest paid annually on a loan taken for acquisition or construction of a self-occupied property.
SECTION 24(B) TAX TREATMENT AT A GLANCE
| PROPERTY STATUS | OLD TAX REGIME | NEW TAX REGIME (SEC 115BAC) |
|---|---|---|
| Self-Occupied | Deduction capped at ₹2,00,000 | Zero deduction against salary |
| Let-Out / Deemed Rented | Full actual interest deductible; max ₹2L loss set off against salary | Deductible only against rental income; no salary loss set-off |
| Under Construction | Claim 1/5th post-completion per year | No pre-construction deduction for self-occupied |
The New Regime Disallowance and Let-Out Rules
The biggest shock for officers switching to the default New Tax Regime under Section 115BAC is the complete erasure of Section 24(b) deductions for self-occupied homes. You get zero deduction against salary income. If the property is rented out or deemed let-out, you can still deduct full actual interest from gross rent under Section 24(b) to compute net annual value, as documented on the Income Tax Department Portal. However, you cannot set off any resulting negative house property loss against your defence salary under the New Regime; that loss simply lapses.
Pre-Construction Interest and Joint Home Loans
Service personnel frequently buy builder flats during field postings, paying interest years before physical possession. You cannot claim Section 24(b) deductions during construction. Instead, you must aggregate all pre-construction interest and claim it in five equal annual instalments, beginning in the financial year construction completes. This instalment gets clubbed with your regular annual interest and remains bounded by the ₹2,00,000 self-occupied cap under the Old Regime.
For co-borrowers—such as an officer and spouse co-owning the home—each person can claim up to ₹2,00,000 under the Old Regime, provided both are co-owners on the title deed and service the EMI from their respective accounts. Retaining a loan merely for the tax rebate rarely makes financial sense when prepaying wipes out non-deductible interest compounding over decades.
