House Property Loss Set-off Under Old Act vs New Act: Checklist, Due Dates & Common Mistakes
Reviewed by CA Nikhil Gupta · Last reviewed 26 September 2026
Corrected 26 September 2026: the earlier version cited wrong Income-tax Act 2025 sections (194, 72, 155), overstated the self-occupied interest deduction (the ₹2 lakh cap covers all self-occupied houses together and any excess is not carried forward), said a late return forfeits the house-property loss (Section 121 does not list it), and gave the wrong return due date for salaried taxpayers.
Millions of home loan borrowers use house property loss — created by home loan interest exceeding rental income — to reduce their salary tax. The Income-tax Act 2025 retains this mechanism but renumbers the sections and tightens regime interaction. The ₹2 lakh annual cap on set-off against other income heads is unchanged. What has changed is how you elect the old regime to access this benefit from Tax Year 2026-27 onwards. This guide provides the full comparison, worked examples, and a filing checklist.
The Core Rule — Same Limit, New Section Numbers
Under both the old Act and the new Act, a taxpayer who suffers a loss under "Income from House Property" (due to home loan interest exceeding net rent or self-occupied property deemed value) can set off this loss against income from other heads — but only up to ₹2 lakh per year. The balance unabsorbed loss carries forward for 8 years.
| Parameter | Old Act — Section | New Act (2025) — Section | Amount/Rule |
|---|---|---|---|
| Self-occupied property — interest deduction | Section 24(b) | Section 22(1)(b) and 22(2)(a) | Max ₹2L per year for all self-occupied houses together (₹30,000 if the acquisition-within-5-years and lender-certificate conditions are not met) |
| Let-out property — interest deduction | Section 24(b) | Section 22(1)(b) | Actual interest (no cap in this section; set-off against other heads is limited to ₹2L) |
| Standard deduction on NAV | Section 24(a) | Section 22(1)(a) | 30% of the annual value (Section 21) |
| HP loss set-off cap vs other heads | Section 71(3A) | Section 109(1)(b) | ₹2L per year |
| Carry forward of unabsorbed HP loss | Section 71B | Section 110 | 8 years — HP income only |
| HP loss set-off in new concessional regime | Section 115BAC(2)(i) | Section 202 (default regime) | NOT ALLOWED |
How House Property Loss Is Created — A Refresher
House property loss arises when deductions under the house property head exceed the taxable rent (or zero, for self-occupied properties):
- Self-occupied property: Annual value is deemed nil (₹0). But interest on home loan is allowed as deduction up to ₹2L. This creates a loss of up to ₹2L per year which can be set off against salary.
- Let-out property: Gross rent minus municipal taxes gives Net Annual Value (NAV). Minus 30% standard deduction and actual home loan interest. If result is negative — house property loss.
- Two self-occupied properties: Under the new Act, you can treat up to two houses as self-occupied, each with a nil annual value (Section 21(6) and (7)). The interest deduction for all self-occupied houses together is capped at ₹2L (Section 22(2)) — the cap is not ₹2L per house.
Worked Example — Home Loan Borrower, Tax Year 2026-27
Priya earns ₹18,00,000 salary. She has a home loan on her self-occupied flat with annual interest of ₹2,80,000. She opts for the old tax regime by filing Form 124 (investment declaration to employer).
| Calculation | Amount (₹) |
|---|---|
| Gross salary income | 18,00,000 |
| Standard deduction (Section 19 — ₹50,000 where the Section 202 regime is not used) | (50,000) |
| Net salary | 17,50,000 |
| House property income — self-occupied (annual value = nil) | 0 |
| Less: Home loan interest allowed (₹2,80,000 paid, capped at ₹2,00,000 for a self-occupied house — Section 22(2)) | (2,00,000) |
| House property loss | (2,00,000) |
| HP loss set off against salary (within the ₹2L limit in Section 109) | (2,00,000) |
| Adjusted gross total income | 15,25,000 |
| Less: 80C deductions (PF, PPF, LIC etc.) | (1,50,000) |
| Net taxable income | 14,00,000 |
| Interest above the cap (₹2.8L − ₹2L) | ₹80,000 — not allowed and not carried forward |
Case Study: Ankit's Two Properties — Old Regime vs New Regime Math
Ankit earns ₹25L salary. He has two home loans: flat A (self-occupied) with ₹2.4L interest, flat B (let-out at ₹14,400/month = ₹1,72,800/year) with ₹2.8L interest.
Old Regime (Form 124 (investment declaration to employer) opted):
- Flat A: HP loss = ₹2L (interest of ₹2.4L capped at ₹2L for a self-occupied house; the ₹40,000 above the cap is not allowed and is not carried forward)
- Flat B: NAV = ₹1,72,800 − 30% (₹51,840) = ₹1,20,960 − ₹2,80,000 interest = HP loss of ₹1,59,040
- Total HP loss = ₹2L + ₹1.59L = ₹3.59L. Set-off cap = ₹2L only. Carry forward: ₹1.59L
- Taxable income after set-off: ₹25L − ₹50K standard deduction (old regime) − ₹2L = ₹22.5L. Tax ≈ ₹5.07L including 4% cess, before any 80C, 80D or HRA claim
Despite two home loans, Ankit's total tax is lower in the new regime because the new-regime slabs (nil up to ₹4 lakh, then 5% to 30% — Section 202) and the higher ₹75K standard deduction outweigh the HP loss benefit. Add ₹1.5L under 80C, health insurance and HRA to the old-regime side and the gap narrows. This is the emerging reality for most borrowers with loans below ₹50L at ~9% interest.
When House Property Loss Set-off Still Makes Old Regime Better
The old regime with HP loss set-off outperforms the new regime when:
- High loan outstanding: Large interest payments (above ₹2.4L/year), especially in early years of a high-value loan
- Multiple deductions stack up: HRA + 80C + 80D + home loan interest together create significant old-regime benefit
- Let-out property: Actual interest on let-out is unlimited deduction — rental income is low, creating a large HP loss
- Effective tax benefit calculation: HP loss benefit = ₹2L × your marginal tax rate. At 30% slab = ₹60,000 tax saving per year.
Common Mistakes to Avoid — Tax Year 2026-27
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Filing in new regime without realising HP loss is not allowed | Miss ₹2L set-off — excess tax paid | Compare regimes; opt old via Form 124 (investment declaration to employer) if beneficial |
| Claiming ₹2.8L interest instead of ₹2L cap for self-occupied | Excess interest is disallowed on processing or in scrutiny | Claim at most ₹2L for all self-occupied houses together; the excess is not carried forward |
| Not filing the return by the due date | A late return does not by itself forfeit a house-property loss (Section 121 lists only capital, business, speculation, specified-business and race-horse losses), but the loss must be computed in a return, and late-filing fee and interest apply | File by the Section 263(1) due date — 31 July 2027 for salaried taxpayers for Tax Year 2026-27 |
| Claiming HP loss set-off without interest certificate from bank | Deduction disallowed in scrutiny | Obtain the lender's provisional or final interest certificate before filing |
| Two self-occupied properties — claiming ₹2L interest on each | The ₹2L cap applies to both together — excess interest disallowed | Claim at most ₹2L in total across all self-occupied houses (Section 22(2)) |

House Property Loss — Key Takeaways
- ₹2L annual cap on HP loss set-off against other income — unchanged in new Act (Section 109(1)(b))
- Only available under old regime — must opt via Form 124 (investment declaration to employer)
- Let-out property: actual interest (unlimited) but loss set-off still capped at ₹2L
- Balance HP loss carries forward 8 years — set off only against HP income
- ITR due date for Tax Year 2026-27: 31 July 2027 for salaried taxpayers (31 August 2027 only for non-audit business or professional income) — collect the lender's interest certificate early
- Compare regimes: for most borrowers with loans under ₹50L, new regime may be cheaper despite losing HP loss
