Form 67 deadline tracker for AY 2026-27: foreign tax credit timing

If you earned any foreign income in FY 2025-26 — US dividends from your RSU portfolio, interest on a US savings account, freelance income from an overseas client — you have two deadlines to track and only one of them is the obvious one.

The obvious deadline is your ITR. For non-audit ITR-2 and ITR-3 filers, that's 31 July 2026.

The less-obvious deadline is Form 67 — the separate electronic filing that lets you claim a foreign tax credit (FTC). Without it, CPC will tax the same foreign dividend twice: once via US withholding, once at your Indian slab rate. For someone in the 30% slab, that's a roughly 56% effective rate on every dollar of dividend.

For AY 2026-27, the Form 67 outer deadline is 31 March 2027 — the end of the assessment year — under Rule 128(9) as amended by CBDT Notification 100/2022 dated 18 August 2022. But "outer deadline" and "best practice" are different things, and the gap between them is where most credits get lost.

This guide is the deadline playbook: the calendar, the case law that has saved late filers, the recovery routes if you've already missed it, and the AY 2026-27-specific quirks that matter.

Note on Form 44: Form 67 is being renamed Form 44 under the new Income-tax Act, 2025 and Rules, 2026. The new form applies from Tax Year 2026-27 onwards, which means returns filed in 2027 for AY 2027-28. For AY 2026-27 — the cycle you're filing in now — Form 67 still applies. See our Form 67 to Form 44 transition guide for the changeover mechanics.

TL;DR

For AY 2026-27, Form 67's outer deadline is 31 March 2027 (end of assessment year, Rule 128(9) post-CBDT Notification 100/2022). Best practice: file Form 67 with or before your ITR, which is due 31 July 2026 for non-audit ITR-2/ITR-3. Updated returns under Section 139(8A) also keep Form 67 alive — and ITATs have held the timeline directory, not mandatory, so late filers have ITAT-direct-acceptance and rectification paths.

The deadline calendar for AY 2026-27

Here's how the year actually unfolds for someone with foreign income in FY 2025-26:

Window	Date	Action
FY 2025-26 closes	31 Mar 2026	Last day to receive foreign income that lands in AY 2026-27
ITR-2 / ITR-3 e-filing utility live	April-May 2026	Schema for AY 2026-27 typically released on the portal
Form 67 filing window opens	Anytime from AY start	You can file Form 67 the day the portal accepts it for AY 2026-27
Best practice: file Form 67	Before or with ITR	So FTC flows through Section 143(1) processing automatically
ITR-2/ITR-3 due date (non-audit)	31 Jul 2026	The filing date most retail investors target
Belated return window opens	1 Aug 2026	Section 139(4) belated return; penalty under Section 234F applies
Belated / revised return cutoff	31 Dec 2026	Last day to file belated or revised return for AY 2026-27
Form 67 outer deadline	31 Mar 2027	Rule 128(9): "on or before the end of the assessment year"
Updated return (ITR-U) window	From 1 Apr 2027	Section 139(8A); Form 67 remains acceptable with ITR-U
ITR-U outer deadline	31 Mar 2031	48 months from end of AY (Finance Act 2025 extension)

The window you actually want to live in is between when the utility goes live (typically May) and 31 July 2026. Everything after that is a recovery operation.

What Rule 128 says — and what ITATs have actually accepted

The text of Rule 128(9)

Rule 128(9) of the Income-tax Rules, 1962 reads, in substance: the statement in Form No. 67 shall be furnished on or before the end of the assessment year relevant to the previous year in which the income from a country outside India has been offered to tax or assessed to tax in India and the return of income has been furnished within the time specified under Section 139(1) or 139(4) or an updated return under Section 139(8A).

This was the major liberalisation. Before CBDT Notification 100/2022 dated 18 August 2022 (Income-tax 27th Amendment Rules, 2022, retrospectively effective from 1 April 2022), the timeline was tied to the ITR due date itself — meaning a one-day delay killed the credit at CPC. The 2022 amendment moved the goalposts to the end of the AY and explicitly extended the window to belated and updated returns.

The directory-vs-mandatory debate

Even with the extended timeline, the CPC's automated processing remains rigid: if Form 67 is not on file when the ITR is processed under Section 143(1), the FTC is denied in the intimation. That triggers either a rectification application or an appeal.

This is where the ITAT case law has built up. Multiple benches have consistently held that Rule 128(9)'s timeline is directory, not mandatory — meaning a procedural lapse on the form does not extinguish the substantive right under Section 90 and the underlying DTAA.

A non-exhaustive list of benches that have ruled along these lines:

• ITAT Pune has held in several orders that the requirement to file Form 67 within the prescribed time is directory and FTC cannot be denied for delayed filing.
• ITAT Indore in Asha Rani Pandya v. DCIT/ACIT held that belated filing of Form 67 does not disentitle the taxpayer to FTC under Section 90/90A, as it is a directory requirement and DTAA rights prevail.
• ITAT Chennai allowed FTC in Smt. Chengam Durga despite delayed Form 67 filing.
• ITAT Delhi has held that Form 67 is procedural and non-compliance does not extinguish the substantive right.
• ITAT Hyderabad has held that FTC cannot be denied for delay in filing Form 67, treating the requirement as directory.
• ITAT Mumbai has held that delay in Form 67 is not fatal and Rule 128 is directory.
• ITAT Kolkata in Vaibhav Das Mundhra v. ADIT held that DTAA benefits override procedural lapses in Form 67 filing.

The high-water mark is the Madras High Court in Duraiswamy Kumaraswamy, which held that Rule 128(9) is directory in nature and filing Form 67 before the final assessment order is sufficient compliance to allow FTC. ITAT benches across India have widely followed this ruling.

The practical upshot: if you miss the 31 March 2027 outer deadline, your credit is not legally dead. But you'll have to chase it through rectification or appeal, which costs time and professional fees. The right approach is to never end up there.

When you should file Form 67 — and when you actually file it

In the Rule book and in real life, two different things happen.

The Rule book ideal: file Form 67 before you file your ITR. The ITR then reads the FTC claim, includes it in Schedule TR, and CPC processes the return with the credit already attached.

The real-life version: most retail investors file Form 67 either alongside the ITR (same day, same session) or shortly before. As long as it's lodged before CPC processes the return under Section 143(1) — usually within 60-120 days of e-verification — the credit typically flows through.

The fallback: file Form 67 anytime before 31 March 2027. The credit is still claimable, but you may need to file a revised return (if within revision window) or a rectification under Section 154 to get CPC to recognise it.

A useful rule of thumb for AY 2026-27:

Your filing date for ITR	When to file Form 67
Filing ITR on or before 31 Jul 2026	Same day or 24 hours before
Filing belated ITR between 1 Aug and 31 Dec 2026	Same day or 24 hours before
Already filed ITR without Form 67	File Form 67 + revised return before 31 Dec 2026
Beyond 31 Dec 2026	File Form 67 by 31 Mar 2027 + rectification or updated return

Our Form 67 FTC calculator walks the numerical side — how much credit you can actually claim under the lower-of-foreign-tax-or-Indian-tax cap.

What if you've already filed your ITR without Form 67?

This is the single most common pattern: you filed ITR-2 in July, didn't realise Form 67 was a separate filing, and now CPC has issued an intimation with FTC denied. You have three routes.

Route 1 — Revised return (cleanest if in window)

If you filed your ITR on or before 31 December 2026, you can file a revised return under Section 139(5) anytime up to 31 December 2026. The play:

1. File Form 67 on the e-filing portal first.
2. File a revised ITR-2 the same day or the day after, with Schedule FSI and Schedule TR updated to reflect the FTC.
3. The revised return supersedes the original; CPC re-processes from scratch.

This is the cheapest route. No litigation, no rectification, no professional fees beyond your usual filing assistance.

Route 2 — Rectification under Section 154

If CPC has already processed your original return under Section 143(1) and denied FTC, you can file a rectification application under Section 154 attaching the Form 67 acknowledgement. The CPC has, in many cases, accepted these — especially post the Madras HC ruling in Duraiswamy Kumaraswamy. If CPC rejects, the next step is an appeal to CIT(A).

Route 3 — Updated return (Section 139(8A))

For taxpayers who missed the revised return cutoff of 31 December 2026, the updated return (ITR-U) is the safety net. Rule 128(9) explicitly covers updated returns. The window is 48 months from the end of AY 2026-27 (so up to 31 March 2031, per Finance Act 2025 extension), but additional tax kicks in: 25%, 50%, 60% or 70% of the tax-plus-interest depending on which 12-month block within the window you file in. Form 67 must be filed before or with the ITR-U.

For most retail investors, the ITR-U cost of additional tax usually exceeds the FTC you're recovering, so this route mainly makes sense when the foreign income is substantial.

Route 4 — Litigation (last resort)

If all administrative routes fail, the ITAT cases above show the judicial path is open. ITAT appeals typically take 2-4 years. For dividend FTCs in the few-thousand-rupee range, this rarely makes economic sense. For RSU vesting FTCs or six-figure dividend portfolios, it can.

The Form 67 to Form 44 transition timing

The Income-tax Act, 2025 replaces the 1961 Act effective 1 April 2026. The new Income-tax Rules, 2026 introduce Form 44, which replaces Form 67. Two timing rules matter:

1. Form 67 still applies for AY 2026-27. FY 2025-26 income was earned under the 1961 Act regime. Even though you're filing in 2026, the form you use is the old Form 67.
2. Form 44 begins from Tax Year 2026-27. Under the new Act's nomenclature, "Tax Year" replaces "Previous Year" and "Assessment Year." For FY 2026-27 income — filed in 2027 — you'll use Form 44 instead of Form 67.

Form 44 retains most of Form 67's structure, but the deadline rule reportedly shifts to 12 months from the end of the relevant tax year in which the foreign income has been offered to tax. The practical effect for AY 2027-28 filers is similar — end-of-AY plus a buffer — but the exact mechanics will become clearer once the AY 2027-28 utility goes live.

For now, anyone reading this for AY 2026-27 should treat Form 67 as the live form and 31 March 2027 as the outer deadline. The transition guide covers the rest: Form 67 to Form 44 transition for AY 2026-27.

Worked timeline example

Meet Priya. She works for Microsoft in Bangalore. During FY 2025-26 she:

• Held vested MSFT RSUs throughout the year.
• Received four quarterly dividends totalling USD 1,200 gross.
• US withholding under the India-US DTAA at the treaty rate of 25% on dividends: USD 300 withheld.
• USD/INR average for the year: ₹87 (illustrative).

So in INR terms:

Item	Amount
Gross US dividend (USD 1,200 × ₹87)	₹1,04,400
US tax withheld (USD 300 × ₹87)	₹26,100
Net dividend credited to her US brokerage account	₹78,300 equivalent

Priya's marginal slab is 30% plus 4% cess = 31.2% effective. Indian tax on the gross dividend: ₹1,04,400 × 31.2% = ₹32,573.

Under the lower-of rule (Section 90 / Rule 128(2)):

• US tax paid: ₹26,100
• Indian tax on the same income: ₹32,573
• FTC available: ₹26,100 (the lower)

Without Form 67, Priya pays the full ₹32,573 to India plus keeps the ₹26,100 already taken by the US. Total tax on a ₹1,04,400 dividend: ₹58,673 — a 56.2% effective rate.

With Form 67 filed correctly, she pays India only ₹32,573 minus ₹26,100 = ₹6,473 over and above what the US already took. Total tax: ₹32,573 — a 31.2% effective rate.

Her AY 2026-27 action plan:

Date	Action
31 Mar 2026	FY 2025-26 closes. She gathers the four 1099-DIV / 1042-S statements from her US broker.
April 2026	She collates Schedule FSI data: country = US, income type = dividend, gross amount in INR using SBI TT buying rates, US tax paid in INR.
May-June 2026	ITR-2 utility for AY 2026-27 goes live. She drafts Form 67 with the 1042-S as supporting proof.
Early July 2026	She files Form 67 first, gets the acknowledgement number, then files ITR-2 with Schedule FSI + Schedule TR populated. Acknowledgement number from Form 67 goes into Schedule TR.
31 Jul 2026	ITR-2 e-verification deadline. She uses Aadhaar OTP.
Sep-Oct 2026	CPC processes under Section 143(1). FTC flows through; intimation matches her self-assessment.

The whole sequence takes a few hours. The total Indian tax saved by doing it right: ₹26,100 — i.e. the entire US withholding amount.

If she'd skipped Form 67 and only realised in December 2026 when CPC issued the FTC-denied intimation, she'd file Form 67 + revised ITR before 31 Dec 2026. If she'd realised only in May 2027, she'd file Form 67 by 31 March 2027 outer deadline, then a Section 154 rectification — which would still work, but slower.

Common mistakes

Filing Form 67 after Section 143(1) processing. The Form 67 needs to be on file when CPC processes your return, not just before the outer 31 March 2027 deadline. CPC processing typically runs 60-120 days after e-verification. If Form 67 lands after processing, you'll get an FTC-denied intimation and have to rectify.

Missing the Tax Residency Certificate (TRC). For DTAA relief under Section 90(4), a TRC from the foreign tax authority is technically required. For US-source dividends, the practical proof retail investors use is the 1042-S or the broker's annual tax statement showing US withholding. For salary income from a US employer, a Form 6166 TRC from the IRS is the conservative document. Filing Form 67 without any supporting proof of foreign tax paid is the fastest route to denial.

Claiming the credit in the wrong assessment year. If a US dividend was withheld in December 2025 but the underlying income is taxable in India in AY 2026-27, the FTC goes in AY 2026-27 — not AY 2027-28. The credit is anchored to the year the income is offered to tax in India.

Double-counting the credit. The lower-of rule means you cannot claim more FTC than the Indian tax on that same foreign income. Some filers populate Schedule TR with the full US tax withheld even when it exceeds the Indian tax on that slice. CPC catches this and denies the excess.

Form 67 vs Schedule TR vs Schedule FSI mismatch. Schedule FSI reports the foreign income country-by-country. Schedule TR summarises the relief claimed. Form 67 substantiates with proof. If the three don't reconcile to the rupee, expect a Section 143(1)(a) intimation flagging the variance.

Forgetting Schedule FA. Foreign asset reporting (Schedule FA) is a separate compliance, but it's the same RSU/dividend portfolio. Filing Form 67 without filing Schedule FA correctly is a classic mistake — see our Schedule FA step-by-step for AY 2026-27.

Skipping the revised return when you forgot Form 67. If you filed ITR-2 in July without Form 67 and only realised in October, the revised return route is cheaper than the rectification route. Both work — but the revised return runs cleanly through CPC, while rectification depends on the officer.

A note on what to do this week

If you're reading this in May 2026 with FY 2025-26 income to declare and you haven't started, here's the minimum-viable next 72 hours:

1. Pull your US broker's consolidated 1099 and 1042-S for tax year 2025.
2. Convert each gross dividend and each withholding amount to INR using SBI TT buying rate on the date of credit. (CBDT accepts SBI TT buying rate as the standard reference.)
3. Tally totals: total gross foreign income, total foreign tax paid.
4. Log into incometax.gov.in, go to e-File → Income Tax Forms → File Income Tax Forms → Form 67.
5. Save a draft. The hard part — having the numbers — is now done.

The actual Form 67 submission can wait until you're ready to file your ITR. But getting the numbers ready in May means July is filing, not scrambling.

The Form 67 deadline isn't the trap people think it is — 31 March 2027 is genuinely generous, and ITATs have your back if you slip. The real cost is the friction: a denied intimation, a rectification application, six months of back-and-forth with CPC. All of which disappears if you file the form before or alongside your ITR.

Pick a Sunday afternoon in June. File Form 67. File ITR-2. Done.
