Claiming Foreign Tax Credit Through Form 67

An Indian resident working part of the year for a foreign client, holding foreign investments, or seconded abroad for a stretch of the financial year usually already knows this income has to be reported on their Indian return, since India taxes its residents on worldwide income. What catches people out is the next step. Tax already paid on that same income abroad doesn't get netted off automatically. It has to be actively claimed as Foreign Tax Credit, through a separate filing called Form 67, and that filing runs on its own clock. Miss it, or treat it as an afterthought once the main return is already filed, and it's entirely possible to end up taxed on the same income twice, not because the law intended that outcome, but because a form that exists specifically to prevent it never went in.

The DTAA and Rule 128 Basis for the Credit

India's Double Taxation Avoidance Agreements exist to stop the same income from being fully taxed twice, once where it's earned and again in the country of residence. For most Indian treaties, the mechanism used is the credit method: the foreign income still gets included in the resident's total income back in India, but the Indian tax otherwise payable on that portion is reduced by a credit for the tax already paid abroad on it. Where no DTAA exists with the relevant country, a separate unilateral relief provision still allows a similar credit, so the absence of a treaty doesn't leave a resident with no relief at all. Rule 128 of the Income Tax Rules operationalises this, setting out how the credit is computed, which documents support the claim, and the currency conversion to use. Under the Income Tax Act, 2025, which took over from the 1961 Act this year, these provisions sit in a single renumbered section, and Form 67 itself is expected to be renamed under the new rules going forward. For a return covering income earned before that transition, though, it's still Form 67 under Rule 128 that governs the claim.

Filing Form 67: The Deadline and the Real Risk of Missing It

Form 67 has to be furnished electronically, and current rules allow it to be filed up to the end of the relevant assessment year, provided the return itself was filed within the original or belated return timeline. Where foreign income gets reported later through an updated return, Form 67 covering that income has to be filed by the date of that updated return instead. This is more breathing room than most taxpayers assume, since the common belief is that Form 67 must go in strictly by the original return due date or not at all. But relying on that extended window is riskier in practice than it looks. Automated return processing frequently flags or denies an FTC claim where Form 67 wasn't on file before the return was processed, regardless of what the rule technically allows, and fixing that after the fact means a rectification request or, failing that, an appeal. Appellate tribunals have repeatedly sided with taxpayers here, holding that filing Form 67 is directory rather than mandatory and that a genuine claim shouldn't be denied for a procedural delay alone. That's reassuring to have on your side, but it's still slower and costlier than filing Form 67 alongside the return in the first place.

Documentation You Need Before You Claim

The credit claim has to be backed by proof that the foreign tax was actually paid, and the rules give more flexibility here than most people expect.

• Form 67 itself, the statement declaring the foreign income and the foreign tax paid or deducted on it
• Proof of the foreign tax payment, from any one of three sources: a certificate from the foreign tax authority, a certificate from whoever deducted the tax, such as a foreign employer, or a self-signed statement backed by a challan, bank counterfoil, or online payment acknowledgement, plus proof of any tax deducted at source
• A Tax Residency Certificate, usually the Indian TRC obtained from Indian tax authorities, used to establish Indian residency to the foreign payer so the correct treaty withholding rate applies at source in the first place
• Records reconciling the foreign tax year with the Indian financial year, since the two rarely line up exactly, along with whatever foreign tax return or assessment documents are available

How the Credit Is Actually Computed

The credit allowed is the lower of two figures: the tax India would otherwise charge on that specific foreign income, and the tax actually paid on it abroad. A DTAA-specified rate for that income category caps it further if lower still. Tax under genuine dispute abroad isn't eligible for credit until resolved, and the credit only ever covers the tax itself, not any interest or penalty charged abroad. Foreign currency amounts convert using the State Bank of India's telegraphic transfer buying rate for the month before the tax was paid. A simple illustration of the lower-of rule helps more than the wording does.

FTC vs DTAA Exemption: Different Mechanisms, Different Outcomes

It's easy to treat 'FTC' and 'DTAA relief' as interchangeable, but they solve double taxation in genuinely different ways. Under the credit method, which is what Form 67 and Rule 128 operate, the foreign income stays inside the resident's total income in India for every purpose: it affects which tax slab other income gets taxed at, it counts toward surcharge thresholds, and it factors into deduction eligibility tied to total income. Only the final tax liability gets reduced, through the credit. Under an exemption method, which some treaty articles provide for specific categories of income, the foreign income is left out of the Indian tax base altogether, or included only to set the rate applied to other income. Most of India's treaties rely on the credit method as their general rule, which is why Form 67 comes up so often. True exemption is the exception, tied to specific treaty articles and income types, not something a resident can choose just because it works out cheaper.

The safest way to handle Foreign Tax Credit is to treat Form 67 as part of filing the return itself, not a task to circle back to once the ITR is done. Keep the foreign tax payment trail, challans, employer certificates, and the TRC, organised through the year rather than reconstructing it at deadline time, and file Form 67 alongside the return rather than banking on the extended window or a tribunal ruling to bail out a late claim.
