Is there a penalty for applying late for Form 10FA?
No penalty runs from the application itself. It is an application for a certificate rather than a return, so there is no daily or monthly charge for having made it later than you might have. The cost lands somewhere else and it is real: every foreign payment made before the certificate reaches the payer is deducted at that country domestic non-resident rate instead of the treaty rate. The excess is then recoverable only under that country own procedure, which is slower and more work than having the certificate in hand would have been.
Can Form 10FB be used for a deduction already made abroad?
Not to reverse it directly. Once a foreign payer has deducted and remitted, the certificate cannot travel back and change what was withheld. It does two useful things instead. It fixes the rate for each remittance once it reaches the payer, and it evidences the treaty entitlement for a recovery claim in the country that took the deduction. Which recovery route is available depends on that country rules, not on India, so the certificate is necessary but it is not the whole answer. Ask what the deducting country refund procedure requires before assuming the certificate is enough.
My foreign client withheld full tax because I had no certificate, what now?
Work forwards and backwards at the same time. Forwards: apply for the certificate for the correct income year and get it to the payer, so that the next payment is deducted at the treaty rate rather than repeating the problem. Backwards: the amount already over-deducted is recovered under the rules of the country that took it, usually by a return or a refund application there, and that needs the certificate as evidence for the period. The two strands are separate pieces of work on different timetables, and the forward one is urgent because it stops the loss growing.
Can I claim the over-deducted foreign tax as a credit in India?
Not the excess. A credit for foreign tax follows the tax properly payable in the other country, which where a treaty applies means the treaty rate. If the payer deducted at its full domestic rate because no certificate had been produced, the difference is not foreign tax properly payable and it is not absorbed by a larger Indian credit. It stays recoverable from the deducting country and nowhere else. People tend to discover this while the Indian return is being prepared, which is late in the day to start a foreign refund claim.
I am an Indian resident who files a Canadian return late, does the penalty double?
No, and the idea that it doubles is one of the more persistent errors on this subject. For the 2025 tax year the ordinary late-filing penalty is five per cent of the balance owing plus one per cent for each full month the return is late, to a maximum of twelve months. A higher charge of ten per cent plus two per cent for each full month, to a maximum of twenty months, applies only where the Canada Revenue Agency issued a demand to file and had charged a late-filing penalty in any of the three preceding tax years. Filing late more than once is not by itself the trigger.
Should I get the certificate before invoicing my foreign client again?
Yes, if the payment is likely to be deducted at source. Every invoice paid before the certificate reaches the payer repeats the same over-deduction and adds another recovery claim to the pile, each with its own evidence and its own timetable in the paying country. Getting the certificate for the relevant year in place first turns a recurring problem into a single one. Where an invoice cannot wait, at least tell the payer an application has been made, and confirm in writing what it will do when the certificate arrives.
Do dual citizens pay taxes in both countries?
Both countries can have a claim, but paying double taxes on the same dollar is the exception rather than the rule. The United States taxes its citizens wherever they live; Canada, India and most others tax on residence. So a dual citizen living in one of them often files in both — a resident return in one, a citizen return in the other — while the credit and exclusion rules mean the total is usually close to the higher of the two, not the sum. Filing twice is not paying twice. See two returns as a dual citizen.
How is foreign tax credit claimed in India?
By furnishing Form 67 with proof of the foreign tax — the certificate or statement from the other country's authority or payer — and by relieving the income under the specific DTAA article rather than generally. The credit is limited to the Indian tax on that income, and it is computed source by source rather than in one pool. The deadline for furnishing Form 67 has been amended more than once, so we confirm it for the year rather than assume. See foreign tax credit in India.
