The Foreign Tax Credit Timing Mismatch: Why India's April-March Year Strands Your Credit, and How to Manage the Gap

A US-based NRI sells nothing and does nothing clever. He simply holds Rs 10 lakh of an Indian dividend-paying portfolio, and in late March 2026 the companies pay out. India deducts TDS on the dividends in the same week, inside its financial year 2025-26, which closes on March 31. Ten months later he sits down to file his US return for calendar year 2026, and the dividend is right there in his US income, because the US year that contains a March 2026 payment is the 2026 calendar year, filed in 2027. The Indian tax was paid in one country's tax year. The US credit for it is claimed in a different one. Nothing went wrong, and yet the credit and the income he is crediting it against are sitting in years that do not line up.

This is the part of cross-border investing that the rate tables never warn you about. The treaty caps the Indian rate, the foreign tax credit cancels the overlap, and on paper you pay the higher of the two rates once. What the paper version hides is the calendar. India's tax year ends in March. Yours ends in December, or on April 5, or on June 30, depending on where you live. So the year you paid Indian tax and the year you claim credit for it at home are routinely different years, and that single fact produces cash-flow drag, paperwork that has to be apportioned across two years, and, in a thin year, credit you simply cannot use.

The 30-second answer: India's tax year runs April 1 to March 31. The US and Canada use the calendar year, the UK runs April 6 to April 5, and Australia runs July 1 to June 30. When India deducts TDS on a dividend, interest payment or capital gain, that Indian tax falls in India's financial year, but the same income falls in whichever home tax year contains the payment date, usually a different period. The treaty still fixes the rate, but the credit can land a full cycle after the Indian tax was paid. The foreign tax credit is also capped at your home tax on that income, so a high Indian tax or a thin home year can leave excess credit. In the US the relief is Form 1116, with a one-year carryback and ten-year carryforward of the excess. The fix is records that map Indian FY tax to your home year, and using carryover where the year does not absorb it.

This is an investments guide, so the lens is the money and the mechanics, not a line-by-line filing manual. The aim is to show you exactly why the mismatch happens, where it costs you, and how to manage it so the credit you are entitled to does not evaporate just because it landed in the wrong year. We will work it through in rupees for a US resident, because the US calendar year against India's April-March year is the cleanest illustration of the gap, and because Form 1116 carryover is the tool most NRIs will actually reach for.

Why the years do not line up in the first place

There is no conspiracy here, just two governments that chose different twelve-month windows and never coordinated them. To see the mismatch clearly you have to put the four windows side by side.

India taxes income over its financial year, April 1 to March 31. Under the old Income-tax Act, 1961 this was the "previous year", and from April 1, 2026 the new Income-tax Act, 2025 renames it the tax year under Section 3, but the dates do not change: it is still April to March. Income that arises and tax that is deducted between those dates belong to that Indian year.

The United States taxes individuals over the calendar year, January 1 to December 31. There is no overlap with the Indian year at either end. An Indian financial year straddles two US calendar years: the April-to-December portion of FY 2025-26 sits in US 2025, and the January-to-March portion sits in US 2026.

Canada also uses the calendar year, January 1 to December 31 for individuals, so it has exactly the same offset against India as the US does.

The United Kingdom runs its tax year from April 6 to April 5. That is tantalisingly close to India's April-to-March window but deliberately not the same. The five-day shift means a dividend paid in, say, the first days of April falls in different years in the two countries, and the UK year that mostly overlaps India's FY 2025-26 is the UK 2025-26 year that ends April 5, 2026, but the match is never exact.

Australia runs its tax year from July 1 to June 30. That is the largest offset of the four. The first quarter of an Indian financial year, April to June, sits in the Australian year that ended on June 30, while the rest of the Indian year falls into the next Australian year.

The practical consequence is the same in every case: a single payment of Indian investment income, with its Indian TDS, has to be relocated into whatever home tax year contains the payment date, and that home year is almost never the same twelve months as the Indian year. The closer your income clusters near the end of India's March year, the more likely the matching home year is the next one, and the further apart the tax and the credit drift.

The treaty fixes the rate, not the calendar

It is worth being precise about what the Double Taxation Avoidance Agreement actually does, because the timing problem survives a perfectly operated treaty. The DTAA does two things on investment income. It caps the rate the source country (India) may charge, for example 10% on dividends for a UK or UAE resident under Article 10, and it obliges the residence country to relieve double taxation, usually by giving a credit for the source-country tax. Both of those are about the amount of tax and which country gets to keep it. Neither of them says anything about when.

So when the treaty is working, you still pay the higher of the two effective rates, once, on each slice of income. What the treaty never promises is that you pay it in the same year in both places. The Indian tax is deducted on the Indian payment date, inside India's April-March year. The credit at home is claimed in the home tax year that contains that same payment date, and then only when you file that home return. The treaty hands you a credit; it does not hand you a time machine. For the rate mechanics themselves, see DTAA relief for NRIs and DTAA mechanics: TRC and Form 10F.

There is a second, sharper limit baked into every credit, treaty or not, and it is the one that turns a timing gap into a real loss. The foreign tax credit is capped at your home country's own tax on that same income. You can never recover more than the home tax on the slice, because the credit's only job is to remove the double count, not to refund the source country's tax. Combine that ceiling with a mismatched calendar and you get the core failure mode of this whole area: Indian tax paid in one year, sitting against a home year that may not have enough tax on that income to absorb it. When that happens, the excess does not refund. It either carries over, where your country allows it, or it is lost.

The two directions of credit, and which one this guide is about

A quick orientation, because "foreign tax credit" runs in two directions for an NRI and the timing problem looks different in each.

The first direction is Indian tax credited at home. India taxes your Indian-source investment income, your Indian dividends, your NRO interest, your Indian capital gains, by deducting TDS at source. Your country of residence then taxes the same income as part of worldwide income and gives you a credit for the Indian tax. This is the everyday case for most NRIs, and it is governed entirely by your home country's rules: Form 1116 in the US, Foreign Tax Credit Relief in the UK, Form T2209 in Canada, the Foreign Income Tax Offset in Australia. This is the direction this guide is about, because the Indian April-March year sitting against your home year is exactly where the credit drifts out of sync.

The second direction is foreign tax credited in India, which arises once you are Resident and Ordinarily Resident and your foreign income enters the Indian return. India then credits the foreign tax through Form 67 (renumbered Form 44 from April 1, 2026), capped at the lower of the foreign tax or the Indian tax. The same calendar mismatch bites there too, in reverse, and India is harsher about it because India allows no carry-forward of an unused foreign tax credit at all. For that direction in full, see foreign tax credit and Form 67 for NRIs. For most NRIs still earning abroad and investing in India, the first direction is the live one, so that is where we will spend the worked example.

Worked example: a March dividend that straddles two US tax years

Take a US-resident NRI, ROR for US purposes, who holds an Indian portfolio. In March 2026, inside India's financial year 2025-26, the companies pay Rs 10,00,000 of dividends. India withholds TDS at source. For a US individual the India-US treaty rate on a portfolio dividend is 25%, which is above India's domestic 20%, so the beneficial Indian rate is the domestic one: 20% base plus 4% cess, an effective 20.8%.

Step 1: the Indian tax, deducted in March 2026 (Indian FY 2025-26).

• Gross dividend: Rs 10,00,000
• Base TDS under Section 195 at 20%: Rs 2,00,000
• Cess at 4% on the tax: Rs 8,000
• Total Indian TDS: Rs 2,08,000, an effective 20.8%
• Net dividend reaching the NRO account: Rs 7,92,000

That Indian tax of Rs 2,08,000 is firmly inside India's FY 2025-26, the year that ends March 31, 2026. The Indian return that reports it is filed later in 2026 for AY 2026-27.

Step 2: where the same dividend lands on the US side.

A dividend paid in March 2026 falls in the US 2026 calendar tax year, which the NRI files in early 2027. So already the income sits in a different year from anything you might intuitively pair with "FY 2025-26". The Indian tax was paid in a year India calls 2025-26; the US credit for it belongs to US tax year 2026. They overlap by exactly the three months January to March 2026, and no more.

Step 3: the US tax and the credit, in a clean year.

Suppose, after currency conversion at the prescribed rate, the dividend carries a blended US tax of about Rs 2,40,000 (a 24% illustrative effective rate on Rs 10,00,000). The US taxes the gross dividend, then gives a foreign tax credit on Form 1116 for the Indian tax, limited to the US tax on that foreign-source income.

• US tax on the dividend, before credit: about Rs 2,40,000
• Foreign tax credit for Indian tax on Form 1116: up to Rs 2,08,000 (below the US tax on the dividend, so fully usable)
• Net additional US tax due: Rs 2,40,000 minus Rs 2,08,000 = Rs 32,000
• Total across both countries: Rs 2,08,000 (India) plus Rs 32,000 (US) = Rs 2,40,000
• Net effective rate: 24%, the US rate, with the Indian tax fully credited

In this clean version the credit does its job and nothing is wasted, because US 2026 had enough US tax on the dividend to absorb the full Indian Rs 2,08,000. But notice what already happened to the cash. The Indian Rs 2,08,000 left his account in March 2026. The US relief for it does not arrive until he files his US 2026 return in early 2027, getting on for a year later. He financed the Indian government for the better part of a year before the credit caught up. That is the cash-flow drag, and it exists even when the credit is fully usable.

Step 4: the same dividend, but a thin US year, and how carryover saves it.

Now suppose 2026 is a low-income year for him: he was between jobs for part of it, took the standard deduction, and his US tax on this foreign passive income works out to only about Rs 1,30,000 rather than Rs 2,40,000. The Form 1116 limitation caps the credit at the US tax on the foreign-source income in the passive category, so:

• Indian tax paid: Rs 2,08,000
• US tax on the dividend (the Form 1116 limit this year): about Rs 1,30,000
• Credit usable in 2026: Rs 1,30,000
• Excess Indian tax that cannot be credited in 2026: Rs 2,08,000 minus Rs 1,30,000 = Rs 78,000

That Rs 78,000 is not lost. Under the US rules it goes into carryover: you can carry the excess back one year, to US 2025, and if it is not absorbed there, forward up to ten years, tracked on Schedule B of Form 1116. So if US 2025 had spare limitation in the passive category, the Rs 78,000 (or part of it) is applied there and you amend or it flows through; if not, it waits, parked, until a future year with enough US tax on foreign passive income to soak it up. The credit survives the thin year. It just does not help you in cash terms until a year that can use it, which might be several years out.

The lesson the two versions teach together: the rate calculation said 24%, full stop. The reality was 24% only if the credit landed in a year that could absorb it, and even then the Indian tax was out of his pocket the better part of a year early. When the year could not absorb it, the credit was real but deferred, and the cash benefit slid years into the future. None of that is visible in a rate table. All of it is the timing mismatch.

Edge cases

The general picture, treaty fixes the rate and the credit cancels the overlap a cycle late, holds most of the time. These are the corners where the mismatch turns expensive, and where you have to manage it actively rather than just wait for it to resolve.

Carryback and carryforward: the safety net, and its limits

The US is the most generous of the four on unused credit. Form 1116 lets you carry an excess credit back one year and forward ten, with the carryover tracked by origin year on Schedule B. After the tenth year, any unused credit expires permanently. The other three countries also relieve double taxation but on different terms, and you should not assume a US-style ten-year window everywhere. The UK gives Foreign Tax Credit Relief but its ability to carry unrelieved foreign tax forward is narrow and source-specific, not a broad ten-year pool. Canada's foreign tax credit is largely a use-it-this-year mechanism, with limited carryforward for the business-income credit and generally none for the non-business (investment) credit, though unused foreign tax can sometimes be claimed as a deduction instead. Australia's Foreign Income Tax Offset is essentially a use-it-or-lose-it offset in the year, with no general carryforward of excess. So the same Rs 78,000 of stranded Indian tax that the US would park for up to ten years could be lost outright for a Canadian or Australian resident in a thin year. The honest read is that carryover is a genuine cushion in the US and a thin or absent one elsewhere, and the planning has to match your country.

The credit limit is the real ceiling, not the treaty rate

People fixate on the treaty rate and forget the limit that actually binds. The foreign tax credit can never exceed your home country's tax on that same income, computed by category. On investment income that limit sits in the passive category on Form 1116, and it is calculated as your US tax multiplied by the ratio of foreign passive income to total taxable income. If the Indian tax on a slice is higher than the US tax on that slice, the difference is excess credit, into carryover it goes, and if you have no other foreign passive income and the carryover never finds a home, it expires. The limit, not the headline rate, is what decides whether your credit is fully usable. A year with a lot of Indian tax and little US tax on foreign passive income is the danger zone, and it is exactly the kind of year a single large transaction can create.

Lumpy capital gains concentrate the whole problem into one year

Dividends and interest trickle in and tend to spread across years, which softens the mismatch. A capital gain on a sale is a single lump in a single year, and that is where the timing and the limit collide hardest. Say you sell a long-held Indian equity holding and realise a Rs 40,00,000 long-term gain. India taxes long-term gains on listed shares under Section 112A at 12.5% on the gain above the Rs 1.25 lakh annual exemption, so roughly Rs 4,84,375 of Indian tax, deducted as TDS in the Indian year of sale. Short-term gains would instead fall under Section 111A at 20%. Now that entire Indian tax lands in one home tax year, the year that contains the sale. If your home tax on that gain in that year is lower than the Indian tax, perhaps because long-term gains are taxed gently at home, or the gain pushed you into a year with offsetting losses, a large chunk of the Indian tax exceeds the home limit. With dividends you might have absorbed that over several years; with one big gain you get one shot at the home limit, and the excess goes to carryover or is lost. If you can choose when to realise a large Indian gain, realise it in a home year that has enough home tax on that category to absorb the Indian tax, not in a year you are already sheltering. For the underlying rates, see capital gains tax on NRI shares and mutual funds.

Currency conversion of the credit, in two different rule books

The mismatch is not only about which year, it is also about what exchange rate, and the two countries use different ones. India converts foreign tax for its own credit (Form 67) at the telegraphic transfer buying rate on the last day of the month before the tax was paid or deducted. But for the direction this guide is about, you are claiming the Indian tax at home, so your home country's conversion rule applies. The US generally requires foreign taxes to be translated into dollars at the exchange rate when the tax was paid (or, for withheld tax, when withheld), with an option in some cases to use an average rate for accrued taxes. The practical effect is that the rupee tax you paid and the dollar credit you claim are converted on different dates from the income itself, and in a year where the rupee moved, the dollar value of the credit will not equal the dollar value of the Indian tax as you first booked it. Keep the rate you used and the date you used it. A mismatch in conversion dates, on top of the mismatch in tax years, is exactly the kind of small discrepancy that draws a query, and exactly the kind you can defend instantly if your records are clean.

Income that straddles the year-end on both sides

The worst combination is income that lands right at a year boundary in both countries. A dividend paid in late March is at the very end of India's year and near the end of nothing in particular in the US, which throws the Indian tax into FY 2025-26 and the US income into 2026. A dividend paid in early April flips: it falls in India's FY 2026-27 but still in US 2026. So two dividends from the same company, two weeks apart, can end up in different Indian years but the same US year, or vice versa. There is no rule to memorise here beyond awareness. When income clusters near March 31, expect that the Indian year and the home year will not pair the way intuition suggests, and reconcile by payment date, not by which Indian year the TDS certificate shows.

Practical management: the short list that actually works

The mismatch is structural and you cannot abolish it, so the goal is to manage it so that no credit is wasted and no cash is stranded longer than it must be. The to-do list is short and unglamorous.

First, keep records that map each Indian payment to both calendars. For every dividend, interest credit and capital gain, record the payment date, the Indian financial year, the Indian TDS, the home tax year the payment falls into, and the exchange rate and date you used to convert the tax. This single table is what lets you claim the credit in the correct home year and defend it if asked. Your evidence is the Indian Form 16A or TDS certificate, your Indian ITR and Form 26AS / AIS, and the bank or registrar statements. For pulling those, see Form 26AS and AIS for NRIs and TDS for NRIs and how to claim refunds.

Second, claim the credit in the home year that contains the payment date, not the Indian year. This is the single most common error: pairing the credit with India's FY because the TDS certificate is labelled that way. The home credit follows the home year the income falls into.

Third, use carryover deliberately where your country allows it. In the US, track every excess on Schedule B and watch the ten-year clock. Where you have a choice about realising lumpy income, steer it into a year that can absorb the credit rather than one that will strand it.

Fourth, where the treaty rate genuinely beats the Indian domestic rate (10% for a UK or UAE resident on dividends), get the rate down at source with a TRC and e-filed Form 10F before the record date, so there is less Indian tax to credit and less to strand in the first place. For US and Canadian individuals, where the treaty rate does not beat the domestic rate, the credit at home is the only lever, so the record-keeping and carryover discipline matter more.

The closing read

The honest read is that the foreign tax credit on Indian investment income almost never lines up cleanly, and that is a feature of two governments choosing different twelve-month windows, not a fault in your filing. India's year ends in March. The US and Canada end in December, the UK on April 5, Australia on June 30. The treaty fixes the rate and the credit cancels the overlap, so you pay the higher of the two rates once, but you pay it on two different calendars, and the credit for the Indian tax can land a full cycle after the Indian tax left your account.

Two things turn that timing gap from an annoyance into a cost. The first is cash flow: you finance the source country for months before the home credit catches up, and no rate table shows that. The second, sharper one is the credit limit: the credit can never exceed your home tax on that income, so a year with heavy Indian tax and thin home tax, exactly what a single large capital gain creates, leaves excess credit that you can only carry over where your country allows it. In the US that is Form 1116 with a one-year carryback and ten-year carryforward, a genuine cushion. In Canada and Australia the cushion is thin or absent, and the same excess can be lost.

So treat the mismatch as a planning fact, not a surprise. Keep a clean table mapping every Indian payment to both tax years and to the conversion rate you used. Claim the credit in the home year that contains the payment date. Where you control the timing of lumpy income, realise it in a year that can absorb the credit. And where the treaty rate beats the Indian rate, get it down at source so there is less to strand. Do those, and the mismatch costs you some cash-flow timing and some paperwork, which is the most it should ever cost. If your situation involves a large straddle-year gain, a thin home year with stranded credit, or a country with no carryforward, that is the point to pay a cross-border adviser rather than rely on a blog, this one included.
