Home Loan Interest Not Shown in Form 16? Claim It in ITR

"My Form 16 does not show my home loan interest, and now my refund looks too small." This happens to thousands of salaried people every year, and it is fixable. Form 16 (Form 130 for salary from tax year 2026-27) is only your employer's view; you can claim the home loan deduction yourself in your income tax return under the old regime, or in a revised return if you have already filed, as long as you meet the deadlines below.

This guide covers returns for FY 2025-26 being corrected now and the current year, FY 2026-27, as of October 2026. For the full set of home loan tax rules, see our pillar guide on home loan tax benefits.

Why it happens

1. You did not submit proof in time. Employers ask for the lender's provisional and final interest certificates by a cut-off, often January or February. Miss it and the claim is dropped.
2. The employer applied the new regime. The new regime is the default for TDS. If you did not tell your employer you wanted the old regime, no home loan deduction for a self-occupied house was allowed, because the new regime does not permit it.
3. The declaration was incomplete. For tax year 2026-27 onward, the declaration to the employer is Form 124 (old Form 12BB). Missing lender details, PAN or the loan's purpose can lead to rejection.
4. Possession came late in the year. Principal and pre-construction interest qualify only after construction is complete, so employers sometimes leave them out entirely.
5. Joint loan confusion. The employer allowed your share at the wrong ratio, or allowed nothing because the certificate was in the co-borrower's name first.

None of these stop you from claiming in your own return, as long as you are eligible.

Which route fits your situation

Returns for FY 2025-26 are governed by the Income-tax Act, 1961; from tax year 2026-27 the 2025 Act numbering applies. Practitioners generally accept that a salaried taxpayer whose original return was filed on time can move to the old regime in a revised return, but if your original return was belated, the old regime is generally closed for that year. Updated returns (ITR-U, old Section 139(8A), now Section 263(6)) cannot be used to claim a missed deduction, because they cannot lower tax or raise a refund.

Worked example: claim it, but compare regimes first

Arjun earns a salary of ₹20,00,000 in FY 2025-26 and told his employer he wanted the old regime. His employer allowed the ₹50,000 standard deduction, ₹1,50,000 under old Section 80C (EPF and PPF), ₹25,000 for health insurance and ₹50,000 for NPS. It left out his home loan interest of ₹2,40,000 on a self-occupied flat because the certificate arrived after the cut-off.

Taxable income in Form 16: ₹20,00,000 − ₹50,000 − ₹1,50,000 − ₹25,000 − ₹50,000 = ₹17,25,000.

How the figures are built:

• Old regime with interest: ₹12,500 (₹2.5-5 lakh at 5%) + ₹1,00,000 (₹5-10 lakh at 20%) + ₹5,25,000 × 30% = ₹1,57,500, total ₹2,70,000. The saving of ₹62,400 equals ₹2,00,000 × 31.2%.
• New regime: ₹20,000 + ₹40,000 + ₹60,000 (the 5%, 10% and 15% slabs to ₹16 lakh) + ₹3,25,000 × 20% = ₹65,000, total ₹1,85,000.

Claiming the missed interest is worth ₹62,400, but switching to the new regime in the return is worth ₹1,50,800. In this example, the old regime would beat the new one only if total deductions, including the standard deduction, crossed about ₹7.6 lakh. Run your own numbers in the income tax calculator before deciding. The slabs for both years are the same, so the comparison holds for FY 2026-27 too.

How to fix it: step by step

1. Download the final interest certificate from your lender for the full year, 1 April to 31 March. It splits interest and principal. Our guide to the home loan interest certificate explains each line.
2. Check eligibility. Self-occupied house, loan for purchase or construction, construction complete within five years of the end of the year the loan was taken (otherwise the cap drops to ₹30,000), and you are an owner and a borrower.
3. Compare both regimes using your full income, not just salary.
4. If you have not filed and are within the due date, file choosing the old regime and enter interest under income from house property and principal under old Section 80C (Section 123 from tax year 2026-27).
5. If you already filed on time, file a revised return on the e-filing portal: choose "revised return", enter the original acknowledgement number and date, and refile the complete return. E-verify within 30 days.
6. Expect a mismatch check. The department compares your return with Form 16. If you get a communication, reply in the e-Proceedings section within 30 days, attaching the interest certificate. Our guide on an income tax notice for a home loan deduction mismatch walks through the reply.
7. For the current year, send your employer the provisional certificate and Form 124 now, and the final certificate before the cut-off, so TDS is right and you do not wait for a refund.

If something goes wrong: where to go

Sample reply to a mismatch query

Assessment year: 2026-27        PAN: [your PAN]

The deduction of Rs [2,00,000] for interest on housing loan
(income from house property, self-occupied) and Rs [amount]
under section 80C for principal repayment were not considered
by my employer in Form 16 because the lender's certificate was
submitted after the employer's proof deadline. I have opted for
the old tax regime in my return filed on [date].

The loan was taken from [lender] for purchase of my residential
house at [city], of which I am [sole/joint, X%] owner and
co-borrower. Possession was received on [date].

Attached: final interest certificate for FY 2025-26,
sanction letter, sale deed / possession letter.
I request that the claim be allowed as filed.

What not to do

• Do not file a belated return expecting the old regime. For most salaried people it will be processed under the new regime, with no self-occupied interest deduction.
• Do not claim more than your share on a joint loan, or the full ₹2 lakh on a house still under construction.
• Do not use ITR-U for this. It cannot reduce tax or increase a refund.
• Do not ignore a mismatch communication. If you do not reply in 30 days, the claim is usually disallowed automatically.
• Do not assume the old regime is better because you have a home loan. Compare first; see new vs old tax regime.

Key takeaways

• Form 16 does not limit your deductions; you can claim home loan interest and principal in your own ITR under the old regime.
• For FY 2025-26, revise by 31 December 2026 for free, or by 31 March 2027 with a fee.
• A belated return generally locks you into the new regime, which allows no self-occupied interest deduction.
• In the example, the missed interest is worth ₹62,400, but the new regime saves ₹1,50,800; always compare.
• Keep the lender's certificate ready and answer any mismatch query on the e-filing portal within 30 days.
