The Foreign Tax Credit and Form 1116 on Indian Income
This is the mechanism people mean when they say “there's a treaty”. It works, but not evenly — and the Indian income most people assume is safe is the one that gets no relief at all.
The short answer
The foreign tax credit reduces your US tax by the Indian tax you paid on the same income, claimed on Form 1116. It is capped at the US tax attributable to your foreign income, and computed separately per income category. The critical asymmetry: income India exempts — NRE interest above all — is still fully taxable in the US and carries no credit at all, because no Indian tax was paid on it.
The NRE trap
Start here, because it is the point that costs people real money and almost nobody sees it coming.
NRE interest is exempt from Indian tax. Most people file that away as good news. But the foreign tax credit only relieves foreign tax you actually paid, and on NRE interest you paid none. Meanwhile the US, taxing you on worldwide income as a resident, taxes that interest in full.
So the Indian exemption you think of as a benefit is exactly what removes your US relief. NRE interest is taxed once, at full US rates, with nothing to offset it.
Compare an NRO account, where Indian tax is deducted and a credit is generally available. The account that looked worse in India may leave you better off once the US return is taken into account. That is not advice to move money — the full picture includes repatriation rules and much else — but it is a reason to stop assuming NRE is automatically the efficient choice once you are a US taxpayer.
How the credit works, and where it stops
A credit reduces your US tax directly, which makes it far more valuable than a deduction against income. But it is limited: it cannot exceed the US tax attributable to your foreign-source income. Broadly, the ceiling is your US tax scaled by the proportion of your taxable income that is foreign-source.
The practical consequence: if India taxed something at a higher effective rate than the US would have, you cannot use all of it this year. The excess is not automatically lost — see the carryover below — but it does not reduce this year's bill.
And the limitation is applied per income category, not to your foreign income as a whole. Passive income — most interest, dividends and gains — and general category income such as salary are computed independently. Excess credit stuck in the passive category cannot reduce US tax on your Indian salary. This catches people who had both in the year they moved.
Indian income, type by type
| Income | Indian tax | US credit | Notes |
|---|---|---|---|
| NRE account interest | None — exempt in India | No credit available | The worst combination. Fully taxable on your US return, with no Indian tax to credit against it. The Indian exemption is what removes your US relief. |
| NRO account interest | TDS deducted | Generally creditable | Passive category. The creditable amount is the Indian tax finally owed, not necessarily the TDS withheld. |
| Fixed deposit interest | TDS deducted | Generally creditable | Passive category, same treatment as NRO interest. |
| Indian rental income | Taxed in India | Generally creditable | The US and Indian computations of taxable rent differ — depreciation and allowable deductions are not the same — so the two figures will not match. |
| Indian salary earned while in India | TDS on salary | Generally creditable | General category. Common in the year you moved, and the financial-year mismatch bites hardest here. |
| Capital gains on Indian shares | Taxed in India | Generally creditable | Passive category. Holding-period and cost-basis rules differ between the two systems, so the gain itself may differ. |
| Gain on selling Indian property | Taxed in India, often with TDS | Generally creditable | Timing is the difficulty: the Indian tax may be paid in a different US tax year from the one the gain falls into. |
| Indian mutual fund distributions or gains | Taxed in India | Generally creditable | But the US side is governed by the PFIC rules, which change what and when you are taxed. Read the PFIC guide first. |
| PPF or EPF accretion | Generally exempt in India | No credit available | And whether the US currently taxes it is genuinely unsettled. If it is taxable, there is no Indian tax to offset it. |
We deliberately quote no Indian TDS rates. They change, they differ by payment type, and a lower-deduction certificate changes them again — a stale rate here would be worse than none.
Your Indian paperwork covers the wrong year
India's financial year runs 1 April to 31 March. The US uses the calendar year. Nothing reconciles them for you.
So your Form 16, your Form 26AS and your AIS each describe a period straddling two US tax years. None can be carried across as-is. The income and the tax both have to be apportioned to the correct US year, and the apportionment has to be consistent between them — crediting a full year of Indian tax against part of a year of Indian income is a mismatch that will not survive scrutiny.
This is one of the most common places a carefully self-prepared cross-border return goes wrong, and it is invisible in generic foreign-tax-credit guidance because it only arises for countries whose tax year is not the calendar year.
TDS withheld is not necessarily what you can credit
What is creditable is the Indian tax you are legally liable for, not the amount withheld at source. If your Indian return produces a refund because TDS over-collected, the creditable figure is the final liability. Taking the TDS number from a statement and later receiving an Indian refund leaves you having over-credited — which has to be put right rather than quietly forgotten. Amounts also have to be translated into dollars, and the correct rate depends on whether you are on the cash or accrual basis for foreign taxes.
When you can skip Form 1116
There is a de minimis election under section 904(j). If all your foreign-source income is qualified passive income reported on a payee statement, and your total creditable foreign taxes are $300 or less — $600 on a joint return — you may elect to claim the credit without filing Form 1116.
It is simpler, and it is not automatically better: electing out means giving up the carryback and carryforward. If you have excess credits worth preserving, the shortcut costs you them.
Credits you cannot use yet
Excess credits generally carry back one year and forward ten, within the same income category. So an unusable credit is not necessarily a wasted one — which is also the strongest argument against electing out of Form 1116 to save paperwork. Choosing a deduction instead of the credit is a further option, usually worse, and it applies to all your foreign taxes for the year: you cannot credit some and deduct others.

Frequently Asked Questions
What does the foreign tax credit actually do?
It reduces your US tax by the foreign income tax you paid on the same income, so the same rupee of income is not taxed fully twice. It is a credit against tax, not a deduction from income, which makes it considerably more valuable. It is claimed on Form 1116 and is the mechanism that delivers what people expect the tax treaty to deliver.
Can I credit all the Indian tax I paid?
Not necessarily. The credit is capped: it cannot exceed the US tax attributable to your foreign-source income. In broad terms the ceiling is your US tax multiplied by the share of your taxable income that is foreign-source. If India taxed something at a higher effective rate than the US would have, the excess is not usable this year — though it may carry.
Do I always have to file Form 1116?
No. There is a de minimis election under section 904(j): if all your foreign-source income is qualified passive income reported to you on a payee statement, and your total creditable foreign taxes are $300 or less — $600 on a joint return — you can elect to claim the credit without filing Form 1116. Electing out also means giving up the carryback and carryforward, so it is not automatically the right choice.
Why can I not use my excess credit from one type of income against another?
Because the limitation is computed separately for each category of income. Passive income — most interest, dividends and capital gains — and general category income, such as salary, are worked out independently. An unused credit sitting in the passive category cannot reduce US tax on general category income. This is a frequent surprise for people with both Indian salary and Indian interest in the same year.
Why does my Indian tax paperwork not match my US tax year?
Because the two years are different. India runs its financial year from 1 April to 31 March; the US uses the calendar year. So your Form 16, Form 26AS and AIS all cover a period that straddles two US tax years, and none of them can simply be copied across. The income and the tax have to be apportioned to the correct US year, which is manual work and one of the more common places a self-prepared cross-border return goes wrong.
Is the TDS on my statement the amount I can credit?
Not automatically. What is creditable is the foreign tax you are legally liable for, so if your Indian return produces a refund of over-deducted TDS, the creditable amount is the final liability rather than the amount withheld. Claiming the TDS figure and later receiving an Indian refund leaves you having over-credited, which requires correcting.
What happens to credits I cannot use this year?
Excess credits generally carry back one year and forward ten, within the same income category. This is why electing out of Form 1116 under the de minimis rule is not always advantageous — you forfeit the carryover. It is also why an unusable credit today is not necessarily wasted.
Should I take a deduction for the foreign tax instead of a credit?
Usually not. A credit reduces tax directly while a deduction only reduces taxable income, so the credit is normally worth more. There are situations where the deduction wins, but the choice applies to all your foreign taxes for the year — you cannot credit some and deduct others — so it is a single decision for the whole return, not a per-item one.
I am an F-1 student. Does any of this apply?
Generally not while you are a nonresident alien, because you are then taxed only on US-source income and there is no foreign income to relieve. It becomes relevant once you are a resident and your Indian income enters your US return — most commonly on moving to an H-1B, which is also the year the financial-year mismatch is at its most awkward.
