Quick Summary — What You Need to Know
- The scare: the Income Tax Act, 2025 — which replaces the Income Tax Act, 1961, effective 1 April 2026 — was initially drafted without the long-standing pre-construction interest deduction that lets borrowers claim interest paid before a property's construction completes, in five equal instalments starting the year of possession.
- The relief: in her Budget 2026 speech, Finance Minister Nirmala Sitharaman announced the government would amend the Income Tax Act, 2025 specifically to restore this pre-construction interest benefit, addressing the confusion the omission had caused among borrowers and tax professionals.
- What actually stays the same: the substantive home loan interest deduction — up to ₹2 Lakh/year for self-occupied property under the old Section 24(b), renumbered as Section 22(2) under the new Act — is unchanged. Only the section numbering moves; your CA may start citing "Section 22" instead of "Section 24(b)" for returns filed from AY 2027-28 onward.
- The trap some borrowers miss: if you've opted into the new tax regime, the self-occupied property interest deduction is blocked entirely — it's only available under the old regime. Let-out property interest remains deductible against rental income either way, without loss set-off against other income.
- Does refinancing affect your deduction? No — the interest deduction is tied to the loan's purpose (purchase, construction, or repair of the property), not to which specific lender currently holds it. Transferring your balance to a new lender at a lower rate does not forfeit this benefit, provided the new loan continues to serve the same qualifying purpose.
- A practical bonus: ITR-1 has been expanded for AY 2026-27 to let salaried taxpayers report income from two house properties, which previously required the longer ITR-2 form — relevant if you're weighing a second property purchase alongside a refinance.

The Scare: What the New Income Tax Act Almost Dropped
The Income Tax Act, 2025 was drafted to replace the decades-old Income Tax Act, 1961, with a cleaner, restructured format — effective 1 April 2026. Somewhere in that restructuring, the specific provision letting borrowers deduct interest paid on their home loan before construction or acquisition completes — the "pre-construction interest" benefit — was omitted from the new Act's initial text.
This mattered because the provision isn't a niche technicality. Under the existing framework, a borrower who takes a loan in, say, 2021 but only gets possession in 2026 can claim the interest paid during that entire gap — just spread across five equal instalments starting the year of possession, rather than lost entirely. Dropping it would have meant real money for anyone mid-construction when the new Act took effect.
The Relief: The Budget 2026 Amendment
In her Budget 2026 speech, Finance Minister Nirmala Sitharaman confirmed the government would amend the Income Tax Act, 2025 specifically to preserve the pre-construction interest deduction for home loan borrowers — addressing the confusion the initial omission had caused just weeks before the new Act's effective date.
Old Act vs. New Act: What Actually Changes
| Provision | Income Tax Act, 1961 (through AY 2026-27) | Income Tax Act, 2025 (from AY 2027-28) |
|---|---|---|
| Self-occupied interest deduction cap | ₹2 Lakh/year, Section 24(b) | ₹2 Lakh/year, renumbered Section 22(2) — unchanged |
| Let-out property interest deduction | Full interest deductible against rental income, no cap | Same — no substantive change |
| Pre-construction interest | 5 equal instalments from possession year | Initially omitted; restored via Budget 2026 amendment |
| Sections 80EE / 80EEA (additional interest deduction) | Closed to fresh loans; only active for existing qualifying loans | Same status — sanction windows already shut |
| ITR-1 house property reporting | Limited to one house property | Expanded to two house properties for AY 2026-27 |

Does Switching Lenders Cost You the Tax Benefit?
No. The home loan interest deduction under Section 24(b) — soon Section 22(2) — is tied to the purpose of the borrowing: purchase, construction, or repair of the property. It is not tied to a specific lender. If you transfer your outstanding balance to a new bank offering a lower rate, the new loan continues to serve the same qualifying purpose, and your interest deduction eligibility continues uninterrupted — you simply claim the deduction against interest paid to the new lender instead.
The New Tax Regime Trap Most Borrowers Miss
If you've opted into India's new (concessional) tax regime, the self-occupied property interest deduction is blocked entirely — it simply isn't available under that regime, regardless of how much interest you're paying. This deduction remains available only under the old tax regime. Let-out property interest, by contrast, stays deductible against rental income under either regime, though without the ability to set off any resulting loss against your other income.
This is worth checking before you refinance: if your motivation includes maximising your tax position alongside a lower rate, confirm which regime you're actually filing under this year.
The Rate Case for Refinancing Right Now
Separately from the tax story, the rate environment itself remains a genuine reason to check your refinance math. RBI cut the repo rate by a cumulative 125 basis points between February and December 2025, then held it through the April and June 2026 meetings — though June 2026 inflation jumped to an 18-month high of 4.38%, and economists are now split on whether RBI holds or hikes at its August 2026 meeting. If your home loan hasn't fully caught up with the 2025 cuts, that gap is worth closing regardless of what happens next. See our full Fixed vs. Floating Interest Rate guide for the detailed breakdown.
Refinancing Without Disrupting Your Tax Position
- Confirm your loan's purpose transfers cleanly. Ensure your balance transfer documentation clearly states the loan continues to be for the same qualifying purpose (purchase/construction/repair).
- Request interest certificates from both lenders for the transition year. You'll need both to correctly compute your total deductible interest for that financial year.
- Recheck your tax regime choice. If you're under the new regime and relying on self-occupied interest deduction, that benefit isn't available regardless of refinancing — factor this into your overall decision.
- If you're still mid-construction, keep your pre-construction interest records organised. You'll need the full history to correctly spread it across the five post-possession instalments.
Illustrative Application: A Refinance Mid-Construction
The Situation
A borrower took a ₹60 Lakh home loan in 2022 for an under-construction flat, with possession expected in 2027 — meaning several years of pre-construction interest would need to be tracked and later claimed.
The Refinance Trigger
By mid-2026, the original lender's rate hadn't kept pace with the 2025 rate cuts, and the borrower wanted to switch to a lower-rate lender well before possession.
The Approach
CreditCares structured the balance transfer to a new lender at a materially lower rate, ensured the transfer documentation preserved the loan's original purchase/construction purpose, and confirmed the borrower's pre-construction interest records remained intact across both lenders.
The Outcome
The borrower secured a lower ongoing rate without any disruption to their eventual pre-construction interest claim, which will still be available in five instalments starting the year of possession.

Conclusion & Next Steps
The Income Tax Act 2025 transition looked, for a brief moment, like it might cost home loan borrowers a genuine benefit — it didn't, once Budget 2026 restored the pre-construction interest provision. What's actually changed is largely cosmetic renumbering, not substance. And if you're considering a refinance to capture the last 18 months of rate cuts, the tax side of that decision is simpler than it might seem: your deduction eligibility follows the loan's purpose, not which bank currently holds it.
