Income Tax Notice for Home Loan Deduction Mismatch: Reply
Got an income tax notice for a home loan deduction mismatch? See what it means, how to reply on the e-filing portal in 30 days, and when to revise or rectify.
In this article
"I received an email from the Income Tax Department saying my home loan interest deduction does not match Form 16 and the claim will be disallowed unless I respond." Do not panic, and do not ignore it. Most of these are not scrutiny notices but a 30-day request to confirm or correct a claim; if your deduction is genuine, reply on the e-filing portal with the lender's interest certificate and the claim is normally allowed. If it was wrong, agree or revise.
This guide covers the communications taxpayers are receiving as of October 2026, mainly for returns of FY 2025-26 (assessment year 2026-27), which are governed by the Income-tax Act, 1961. From tax year 2026-27, the same steps apply under the renumbered Income-tax Act, 2025. For the deduction rules themselves, see our pillar on home loan tax benefits.
Why it happens
The processing centre compares your return with Form 16, Form 26AS, AIS and the limits in the law. A home loan claim is flagged when:
- The deduction is not in Form 16. You claimed interest or principal directly in your ITR because your employer did not include it. This is allowed, but it looks like a mismatch. See home loan deduction missed in Form 16.
- Form 16 shows the new regime and your ITR uses the old one. A common trigger, and usually valid for salaried taxpayers who filed on time.
- The claim exceeds a cap. More than ₹2 lakh of interest on a self-occupied house, or principal pushing old Section 80C beyond ₹1.5 lakh.
- The claim is not allowed at all. Self-occupied interest under the new regime, full pre-construction interest in one year instead of five instalments, or principal on a house still under construction.
- Joint owners claimed too much. Each co-owner can claim only their share, and both together cannot claim more than the interest actually paid.
The department has also run "NUDGE" campaigns by SMS and email, asking taxpayers whose deductions look risky to review them and revise voluntarily. Those are not demands, but they signal that a claim has been flagged.

Worked example: reply or correct?
Neha filed her FY 2025-26 return on time under the old regime, in the 30% slab. Her employer applied the new regime in Form 16, so it showed no home loan deduction. In her ITR she claimed ₹2,00,000 of interest on a self-occupied flat she owns jointly with her husband, 50% each. The total interest paid on the loan was ₹3,00,000.
She received a proposed adjustment to disallow the ₹2,00,000.
Her correct claim: her 50% share of ₹3,00,000 = ₹1,50,000, below the ₹2 lakh cap.
| Amount | |
|---|---|
| Claimed | ₹2,00,000 |
| Correctly allowable | ₹1,50,000 |
| Excess claim | ₹50,000 |
| Tax on excess at 31.2% (30% + 4% cess) | ₹15,600 |
| Tax saved by the valid ₹1,50,000 | ₹46,800 |
If she ignores the communication, the whole ₹2,00,000 is disallowed and she loses ₹62,400 of tax benefit (₹2,00,000 × 31.2%). If she disagrees in full, she risks the excess being picked up later. The right answer: disagree in part, accepting the ₹50,000 excess and supporting ₹1,50,000 with the interest certificate and sale deed. Her refund falls by ₹15,600 rather than ₹62,400.

How to reply: step by step
- Confirm the notice is real. Log in to incometax.gov.in yourself; do not click links in the email. Genuine communications appear under Pending Actions, then e-Proceedings, with a document identification number.
- Note the deadline. For a proposed adjustment it is 30 days from the date of the communication.
- Read exactly what is being adjusted. It lists the item, the amount in your return and the amount the department proposes.
- Check your claim against the rules. Ownership, borrower status, self-occupied or let-out, completion of construction, the ₹2 lakh and ₹1.5 lakh caps, and the regime chosen. The home loan interest certificate guide explains how to read the lender's figures.
- Choose your response:
- Agree if the claim was wrong.
- Disagree with a reason, such as "deduction claimed directly in ITR; not considered by employer", and upload the interest certificate, sale deed or allotment letter, and possession or completion certificate.
- Partly agree if only part is wrong, and state the correct amount.
- Submit and save the acknowledgement. Download the response PDF.
- Watch for the intimation. When the return is processed, check that the claim was allowed as per your response.
If the adjustment was already made
| Situation | Route | Old section | 2025 Act | Time limit |
|---|---|---|---|---|
| Valid claim disallowed despite your reply, or no proper chance to reply | Rectification request on the portal (Services, then Rectification) | 154 | 287 | Generally four years from the end of the year of the order under the old law |
| You want to correct the return yourself | Revised return | 139(5) | 263(5) | FY 2025-26: 31 March 2027 (fee after 31 December 2026); tax year 2026-27: 31 March 2028 |
| Claim was wrong and the revision window has closed | Updated return (ITR-U), paying tax, interest and additional tax of 25% to 70% | 139(8A) | 263(6) | Up to 48 months from the end of the assessment year |
| Disagreement on law, not an apparent mistake | Appeal to the Commissioner (Appeals) | 246A | Renumbered | 30 days from the order under the old law |
| Portal or processing problem | e-Nivaran grievance on the portal, then CPGRAMS | — | — | After the portal shows no progress |
Rectification fixes mistakes apparent from the record. It cannot add a new deduction you never claimed. For revisions, our guide to the revised return explains the fee and steps.
Sample response in e-Proceedings
Response to proposed adjustment, AY 2026-27, PAN [ ]
I partly disagree with the proposed adjustment of ₹2,00,000 under interest on borrowed capital (self-occupied property).
The house at [address] is jointly owned by me and my spouse in equal shares, and we are co-borrowers of loan account [number] with [lender]. Total interest for FY 2025-26 was ₹3,00,000, of which my share is ₹1,50,000. I accept the adjustment of ₹50,000 and request that ₹1,50,000 be allowed.
The claim was made directly in the return under the old regime, filed on [date], because my employer computed TDS under the new regime and did not consider it in Form 16.
Attached: lender's interest certificate, sale deed showing joint ownership, possession letter.
What not to do
- Do not ignore the 30-day window. An unanswered proposed adjustment is applied automatically.
- Do not click links or call numbers in an email claiming to be from the department. Use only the portal.
- Do not defend a claim you cannot document. If the certificate does not support it, agree and correct it.
- Do not claim self-occupied interest under the new regime. It is not allowed; only let-out property interest is.
- Do not file ITR-U to increase a refund. It can only increase tax.
Key takeaways
- Most home loan mismatch communications are proposed adjustments under the old Section 143(1)(a) provision (Section 270(1) of the 2025 Act), not scrutiny.
- Reply on the e-filing portal within 30 days: agree, disagree with documents, or partly agree.
- A deduction not shown in Form 16 is valid if you are eligible and filed under the old regime on time.
- If the adjustment is already made, use rectification (old Section 154, now Section 287), a revised return, or appeal.
- In the example, a partial disagreement keeps a ₹46,800 tax benefit instead of losing all ₹62,400.
Frequently asked questions
Why did I get a notice about my home loan deduction?
Usually because the deduction in your return is higher than what your employer reported in Form 16, or the claim breaks a limit such as the ₹2 lakh cap on self-occupied interest. The department's processing centre flags the difference and asks you to confirm or correct it before processing your return.
How many days do I have to respond to a proposed adjustment?
Thirty days from the communication under the old Section 143(1)(a) provision. If you do not respond, the adjustment is made automatically when the return is processed, which can reduce your refund or create a demand.
How do I reply to the notice?
Log in to the e-filing portal, open Pending Actions and then e-Proceedings, select the communication and choose to agree or disagree with each item. If you disagree, give a short reason and upload the lender's interest certificate and ownership proof.
What if the deduction has already been disallowed in the intimation?
If the claim was valid and the error is apparent from your return, file a rectification request on the portal (old Section 154, now Section 287). If the revision window is still open, a revised return is another route. You can also appeal within the time stated in the order.
What if my claim was actually wrong?
Agree to the adjustment, or file a revised return if the window is open. After it closes, an updated return (ITR-U) lets you correct it with additional tax. Correcting early avoids further enquiries and penalties.
