Lesser Tax
16 min read
Quick answer: Form 1116 is how a US resident claims a credit for income tax paid to India so the same rupee of income is not taxed twice. If your Indian bank withheld TDS on NRO interest, or a mutual fund paid TDS on capital gains, or you paid Indian salary tax in your move year, that Indian tax goes on Form 1116 (passive or general category) and reduces your US tax dollar for dollar, up to a limit tied to the share of your worldwide income that came from India. The credit is capped per category; any excess carries back one year and forward ten.
Key takeaways
- Form 1116 is required unless your total creditable foreign taxes are "$300 ($600 if married filing a joint return)" and all your foreign income was passive and reported on 1099-DIV/INT (IRS instructions for Form 1116, 2025).
- You generally fill out a separate Form 1116 for each category of income. The two that matter for most NRIs are passive category income (interest, dividends, capital gains) and general category income (salary and self-employment) (IRS instructions for Form 1116).
- Under the India-US treaty, Indian tax on interest paid to a US resident is capped at "15 percent of the gross amount of the interest" (10% if the loan is granted by a bank or similar financial institution). Only tax you legally owe is creditable, so you can't credit more than that cap even if the bank withheld more (India-US treaty, Article 11).
- Unused credit "can carry back 1 year and then forward 10 years" within the same category (IRS instructions for Form 1116).
- Nonresident aliens generally cannot take the foreign tax credit; the credit is for US residents and citizens reporting worldwide income (IRS instructions for Form 1116).
When do you actually file Form 1116?
You file Form 1116 whenever you are a US tax resident (green card, met the substantial presence test, or elected to be treated as a resident) and you paid or accrued foreign income tax that you want to credit against your US tax. The alternative is to deduct it on Schedule A, but a credit is almost always better because it reduces US tax dollar for dollar, while a deduction only reduces taxable income.
There is one shortcut. The instructions describe an election to skip Form 1116 entirely: "You can elect to claim the foreign tax credit without filing Form 1116. By making this election, the foreign tax credit limitation (lines 15 through 23 of the form) won't apply to you." Conditions are strict: all foreign income is passive category, every rupee of foreign tax is reported on a qualified payee statement like 1099-DIV or 1099-INT, and total foreign taxes are not more than "$300 ($600 if married filing a joint return)" (IRS instructions for Form 1116).
For most NRIs this election does not apply, because Indian banks and brokers don't send US 1099s. The TDS on your NRO fixed deposit shows up on a Form 16A from the bank, not a 1099-INT, so even if your Indian tax is under $300 you usually still file Form 1116.
Nonresident aliens on Form 1040-NR mostly cannot take the credit. The instructions are explicit: "If you are a nonresident alien, you generally can't take the credit" (IRS instructions for Form 1116). If you were dual-status in your move year, the credit is available only for the resident portion. See dual-status returns and the W-8BEN trap for how that split works.
Which category of income does your Indian tax belong in?
Form 1116 asks you to pick a category at the top. Each category gets its own Form 1116 and its own limit. The IRS lists several, but for an Indian in the US only two usually apply:
- Passive category income. The instructions say: "Passive category income consists of passive income and specified passive category income" and "Passive income generally includes" interest, dividends, royalties, and most capital gains (IRS instructions for Form 1116). TDS on NRO interest, dividends on Indian shares, and capital gains distributions all go here.
- General category income. This is "income that isn't section 951A, foreign branch, passive, or any of the other categories." Salary from an Indian employer in your move year, Indian consulting income, and self-employment income from India fall here (IRS instructions for Form 1116).
If you have both, you file two Form 1116s. You cannot combine them, and the limit on one category cannot absorb excess tax from the other.
A quirk worth knowing: there is a special "high-taxed income" rule. If the foreign tax on an item of passive income exceeds the highest US rate that would apply to that income, it is kicked out of passive and recharacterised as general category: "High-taxed income is income if the foreign taxes you paid on the income... exceed the highest applicable U.S. tax rate" (IRS instructions for Form 1116). In practice this rarely bites NRO interest because 15% Indian TDS is below the top US rate, but it can hit short-term capital gains with heavy Indian tax.
| Indian income type | US category | Why |
|---|---|---|
| NRO interest, TDS withheld by SBI/HDFC | Passive | Interest is passive by default |
| Dividends on Indian shares | Passive | Dividends are passive |
| Capital gains on Indian equity/MF/property | Passive | Gains are passive |
| Salary from an Indian employer in move year | General | Compensation for services |
| Freelance/consulting income billed from India | General | Earned income |
| India rental income (net) | Passive | Rental income is passive unless active trade |

How much Indian tax is actually creditable?
Only "tax you legally owe." The instructions set a boundary that trips up a lot of first-time filers: "Taxes paid to a foreign country that you don't legally owe, including amounts eligible for refund by the foreign country" are not creditable. "If you don't exercise your available remedies to reduce the amount of foreign tax to what you legally owe, a credit for the excess amount isn't allowed. The amount of tax actually withheld by a foreign country isn't necessarily 100% creditable" (IRS instructions for Form 1116).
The treaty worked example in the instructions makes this concrete: "Country X withholds $25 of tax from a payment made to you. Under the income tax treaty between the United States and Country X, you owe only $15 and can claim a refund from Country X for the other $10. Only $15 is eligible for the foreign tax credit" (IRS instructions for Form 1116).
Apply this to India. Under Article 11 of the India-US treaty, interest paid to a US resident "may also be taxed in the Contracting state in which it arises... but if the beneficial owner of the interest is a resident of the other Contracting state, the tax so charged shall not exceed... 15 percent of the gross amount of the interest in all other cases" (India-US treaty). Indian banks apply TDS on NRO interest at a higher statutory rate when no treaty benefit is claimed. If you did not claim the treaty rate at the bank with a Form 10F and tax residency certificate, you were legally owed only the treaty amount, and the excess sits in refund territory, not credit territory.
The practical answer: claim the treaty rate in India (file Form 10F with a US tax residency certificate — Form 6166 and Form 10F for claiming treaty benefits) so Indian withholding matches what you legally owe. Then the full Indian tax is creditable.
Form 1116, line by line, for a typical NRI situation
Say Priya is on H1B in Seattle, passed the substantial presence test in 2025, and has:
- $150,000 US salary (W-2).
- $4,000 NRO interest from an SBI deposit. Bank withheld 15% TDS (Form 10F on file), so Indian tax paid = $600.
- $20,000 long-term capital gain on Indian equity, Indian tax paid = $2,500.
She files one Form 1116 for passive category.
Part I - foreign source income. Line 1a asks for gross foreign source income in this category. Priya puts "India" on top and $24,000 ($4,000 interest + $20,000 gain) on line 1a. Deductions definitely related to that income go on line 2 (investment fees paid to the Indian broker, say $100).
Allocations. Lines 3a-3d allocate standard deduction and other "not definitely related" deductions to foreign source income on a ratable basis. If her AGI is $174,000 and foreign source income is $24,000, the standard deduction gets apportioned by that ratio. Line 7 is the result: her net foreign source taxable income in this category.
Qualified-dividend / capital-gain adjustment. This is the step most TurboTax screenshots skip and the IRS highlights twice. If Priya's long-term capital gain is taxed at 15% US (because she's in that bracket), she must multiply the gain by 0.4054 before putting it on line 1a: "multiply your foreign source qualified dividends or capital gain distributions in each separate category by 0.4054 if the foreign source qualified dividends or capital gain distributions are taxed at a rate of 15%, and by 0.5405 if they are taxed at a 20% rate" (IRS instructions for Form 1116). So the $20,000 gain becomes $8,108 on line 1a, not $20,000.
There is an exception. The instructions say she can skip the adjustment "if you qualify for the adjustment exception," which requires that "the amount of your foreign source capital gain distributions plus the amount of your foreign source qualified dividends is less than $20,000" and that her taxable income is below $394,600 MFJ / $197,300 single (IRS instructions for Form 1116). Priya's foreign source gain is exactly $20,000, so she does not qualify and must adjust.
Part II - foreign taxes paid. The Indian tax goes in US dollars using the exchange rate on the date paid: $600 for TDS, $2,500 for the capital gains tax. Line 8 total: $3,100.
Part III - the limit. Line 15 is net foreign source taxable income. Line 18 is total taxable income from Form 1040. Line 19 is the ratio. Line 20 is total US tax before credits. Line 21 is the limit (ratio × US tax). Line 22 is the smaller of foreign tax paid (line 14) or the limit (line 21). That is the credit.
If her limit works out to $2,800 and her Indian tax was $3,100, she claims a $2,800 credit this year and carries $300 forward (passive category carryover).
The limit, in plain English
The formula is: foreign tax credit allowed = (foreign source taxable income in this category / total worldwide taxable income) × total US tax. The point is to make sure you can only credit as much Indian tax as the US was going to charge on that same Indian income. If India taxes it at 30% and the US only taxes it at 22%, the credit is capped at the 22% US amount.
The qualified-dividend adjustment at 0.4054 is just the limit formula remembering that long-term gains are already taxed at 15% in the US. If it didn't scale them down, you'd be computing a limit assuming your gain was taxed at your full ordinary rate, and getting a bigger credit than you deserve.
What happens to excess credit?
Excess credit does not vanish. From the instructions: "You can carry back 1 year and then forward 10 years any foreign tax you paid or accrued to any foreign country or U.S. territory... on income in a separate category that is more than the limitation" (IRS instructions for Form 1116).
Rules worth noting:
- Carryback and carryforward stay within the same category. Passive excess can only offset passive income in another year, not general.
- To use the carryback you have to amend the prior-year return: "File Form 1040-X or other amended return and a revised Form 1116 for the earlier tax year to which you are carrying back excess foreign taxes" (IRS instructions for Form 1116).
- "The carryback-carryforward period can't be extended even if you are unable to take a credit in 1 of the intervening years" (IRS instructions for Form 1116). If you don't have foreign source income in a future year, that carryforward can expire unused.
- You now need Schedule B (Form 1116) to reconcile prior-year foreign tax carryover with the current year (IRS instructions for Form 1116).
For Indian capital gains this matters a lot. India charges long-term capital gains tax on equity even for small gains, and the Indian rate is often above what the US charges on the same gain, so a residual excess credit is common. Keep the carryover schedule year to year. If you don't, you lose it.
Common NRI scenarios
NRO interest with 15% TDS
Report the gross interest as US taxable interest. Form 1116 passive category: foreign source income = gross NRO interest, foreign tax = TDS × USD rate. Credit normally covers the entire US tax on that interest at a 22% or 24% marginal bracket.
Resident Indian salary in the move year
If you moved to the US mid-year on H1B, your pre-move salary from Infosys was Indian source and Indian tax was withheld. If you file as a US resident for the full year (because of a first-year choice or MFJ election), that salary goes on your 1040 as world wages and on Form 1116 (general category). If you file dual-status, the pre-move salary isn't on your US return at all, so no 1116.
Indian mutual funds (PFICs)
A PFIC on Form 8621 is a separate universe. Any Indian tax on gains/dividends from an Indian equity mutual fund is still creditable in passive category, but the US tax under section 1291 excess-distribution regime is nasty. See Indian mutual funds, Form 8621 and what it costs.
Capital gains on sale of Indian property or shares
Indian long-term capital gains tax (now with the revised rates under India's 2024 and later Finance Acts) is paid in India. Report the gain on US Schedule D, then put it on Form 1116 passive category with the qualified-dividend/capital-gain adjustment at 0.4054 or 0.5405 depending on the US rate.
Dividends on Indian shares
TDS applies in India. Treaty cap on dividends to an individual is "25 percent of the gross amount of the dividends" (India-US treaty, Article 10). Credit the Indian tax actually withheld (up to that cap) in passive category.
Credit vs deduction: how to choose
You can take foreign tax as a deduction on Schedule A instead. The credit is almost always better: it reduces tax dollar for dollar, while a deduction only reduces taxable income by your marginal rate. The only time a deduction wins is if the credit is entirely wasted — for example, you have no US tax liability and can't carry the credit anywhere useful.
You can change your mind. The instructions say: "You may make an election to claim a credit or to change from claiming a deduction to claiming a credit at any time before the end of a special 10-year limitation period described in section 6511(d)(3)" (IRS instructions for Form 1116). Going the other way (credit to deduction) is subject to the standard 3-year period. So if you deducted Indian tax by mistake in 2022, you can still switch to a credit through 2032.
Mistakes we see every filing season
- Missing the qualified-dividend adjustment. Taxpayers put the full Indian capital gain on line 1a, overstate the limit, and claim a credit the IRS disallows on examination.
- Crediting over-withheld TDS. Bank withheld at 30% because no Form 10F was on file. Only the treaty-cap amount (15% for interest) was legally owed. The excess 15% is a refund claim in India, not a US credit.
- Wrong category. Indian salary dropped into passive, Indian interest dropped into general. The limits are per-category and the mismatch blows up both.
- Ignoring carryovers. Not tracking the passive-category carryforward on Schedule B (Form 1116), so when a big Indian gain year arrives there is no cushion.
- Trying to claim 1116 as a nonresident alien. It's not allowed except in narrow cases (IRS instructions for Form 1116).
- Claiming Indian tax that was refunded. If you claimed a TDS refund in India, that portion is not creditable.
FAQ
Can I claim the credit if the Indian tax year and US tax year don't match?
Yes. The US tax year is the calendar year for individuals. You claim credit for Indian income tax "paid or accrued during your tax year" (IRS instructions for Form 1116). Pub 514 spells out the timing: "If you use the cash method of accounting, you can claim the credit only in the year in which you pay the tax" (IRS Publication 514). So for a cash-basis filer, the Indian tax goes on the US return for the calendar year you actually paid it, regardless of which Indian financial year it maps to.
Is Advance Tax or self-assessment tax paid in India creditable?
Yes, if it is Indian income tax on income you are also reporting on your US return. The timing follows your cash or accrual basis.
Does GST on Indian expenses count?
No. The credit is for "income, war profits, and excess profits taxes" (IRS instructions for Form 1116). GST, stamp duty, and property registration charges don't qualify.
Do I need to attach anything to prove Indian tax paid?
Not with the e-filed return, but you need to be able to show Form 16/16A, Form 26AS, or receipts for Advance Tax if the IRS asks. Keep them for at least seven years.
Can I use Form 1116 and the Foreign Earned Income Exclusion (Form 2555) in the same year?
Yes, but not on the same income. If you exclude Indian salary under Form 2555, you can't also credit the Indian tax on that same excluded salary. Most H1B holders in the US don't qualify for Form 2555 anyway because they are not residents of India for the physical presence test.
What's "Schedule B (Form 1116)"?
A separate schedule that reconciles prior-year unused credit carryover with the current year. The instructions require it: "Use Schedule B (Form 1116) to reconcile your prior-year foreign tax carryover with your current-year foreign tax carryover" (IRS instructions for Form 1116). If you have no carryover and generated none this year, you don't need it.
Can I take the credit for state income tax paid to a US state?
No. Form 1116 is for foreign taxes. US state income tax goes on Schedule A as an itemized deduction, subject to the SALT cap.
