Foreign Tax Credit Baskets — Passive vs General Income
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Foreign tax credit baskets are the separate income categories on Form 1116 — principally passive and general — into which foreign income and the foreign tax paid on it are sorted. The credit limit is computed basket by basket, so surplus credit in one category cannot offset U.S. tax on income in another. It is why many expats who paid ample foreign tax still owe the IRS.

What are the main baskets?
- Passive category: dividends, interest, rents, royalties, annuities, and most capital gains.
- General category: wages, self-employment income, and most business income — everything not assigned elsewhere.
- Narrower categories apply in specific cases: a foreign branch category for income of a foreign business you run directly or through a disregarded entity, a treaty re-sourced category for income a treaty treats as foreign, and others that rarely touch individuals.
Each basket gets its own Form 1116 and its own limit.
How is the credit limit computed within a basket?
The credit for a basket cannot exceed the U.S. tax on the foreign-source income in that basket — roughly, U.S. tax × (foreign-source income in the basket ÷ total taxable income). Foreign tax above that limit is "excess credit," carried back one year and forward ten years within the same basket. Foreign tax below the limit leaves "excess limitation" that can absorb carryovers from other years.
Why do expats end up with stranded credits?
The classic pattern: a high-tax country taxes salary heavily, producing large general-basket credits, while the expat's U.S. tax comes mostly from U.S.-source investment income — which is not foreign-source at all and sits outside every basket. The general-basket credit can't touch it. Or the mirror image: a country taxes investment income heavily (passive basket) while the expat excluded their salary under the foreign earned income exclusion, so there is little general-basket U.S. tax and the passive credits can't cross over. Credits pile up in one basket, carried forward year after year, while tax is owed in another.
What is the high-tax kickout?
A rule that moves passive income out of the passive basket and into the general basket when the foreign tax on it exceeds the highest U.S. rate that would apply. The effect is to stop heavily taxed investment income from being limited by the small passive-basket limit, letting its tax be credited against general-basket U.S. tax instead. It applies automatically item by item; software handles the mechanics, but it changes outcomes enough that it's worth knowing it exists.
How does the exclusion interact with the baskets?
Foreign tax attributable to income you excluded under the foreign earned income exclusion is not creditable at all — it is scaled out of the general-basket computation. So excluding salary both removes the income and removes the proportionate foreign tax from the credit calculation. In high-tax countries this is a reason to consider the credit alone rather than the exclusion plus credit.
Do carryovers really get used?
Only if a later year has excess limitation in the same basket — more U.S. tax on foreign income in that category than foreign tax paid. For an expat who stays in a high-tax country, general-basket carryovers often never get used and expire after ten years. They become usable when circumstances change: a move to a lower-tax country, a year with U.S.-sourced work that is still foreign-basket under a treaty, or a shift in income mix.
Frequently asked questions
Can I choose which basket my income goes in?
No. Classification follows the type of income and the rules. The high-tax kickout and treaty re-sourcing are the mechanisms that move items, not elections.
I paid foreign tax on my U.S. dividends. Which basket?
None — U.S. dividends are U.S.-source and generate no foreign-source income to support a credit, unless a treaty re-sources them (reported in the treaty basket with Form 8833).
Do I file a separate Form 1116 for each basket every year?
Yes, including years you're only tracking a carryover, so the schedule of carryovers stays current.
Is there a simplified option?
If your creditable foreign taxes are small and entirely passive, reported on payer statements, you may claim the credit without Form 1116 — but then no carryover is allowed.
