The case for high-earners FTC rather than FEIE is simple for well-paid Americans residing in the UK: the Foreign Tax Credit typically eliminates your US payment, and banks save credits for future years, and it covers investment income that the exclusion ignores. The exclusion caps out; the credit rarely does.
Every US citizen files a US return on worldwide income for life, wherever they live. Two mechanisms stop the same pounds being taxed twice. The Foreign Earned Income Exclusion (FEIE), claimed on Form 2555 under Internal Revenue Code §911, lets you carve a slice of earned income out of the US calculation altogether. For 2026, that slice is $132,900 (it was $130,000 in 2025 and $126,500 in 2024, and it rises with inflation each year).
The Foreign Tax Credit (FTC), claimed on Form 1116, works differently. Instead of removing income, it hands you a dollar-for-dollar credit against your US liability for the foreign tax you have already paid.
If your UK tax on a category of income is bigger than the US tax on the same income — and in the UK it very often is — the credit swallows the whole US charge and leaves a surplus. That surplus is the quiet engine behind the case for FEIE-first thinking being wrong for anyone with a serious salary. We unpack the mechanics further in our guide to how the Foreign Tax Credit and Form 1116 work.
The UK is a high-tax country. Once earnings exceed £125,140, the marginal rate reaches 45%, and the £100,000–£125,140 band carries an effective rate of 60% as the personal allowance tapers away. US federal rates top out at 37%. When the foreign rate sits above the US rate, the credit method almost always produces a lower — usually zero — US result. That single fact is why, for UK-resident clients, high-earner FTC, not FEIE, is the default recommendation we give, and only rarely the other way round.
Once your salary increases, the exclusion disappoints for five specific reasons.
The FEIE only removes the first $132,900 of earned income. Everything above that is still fully US-taxable. Worse, the stacking rule in §911(f) taxes that excess at the rate that would have applied had you never claimed the exclusion. Your top slice is not gently taxed from the bottom bracket up; it is stacked on top of the excluded amount and taxed at your real marginal rate. Therefore, the headline save is less than what the exclusion figure indicates. We break down the maths in our explainer on the FEIE stacking rule. This is the first pillar of the high earners FTC, not FEIE, case.
Salary, wages, and self-employment profit are the only things covered by Form 2555. Dividends, interest, capital gains, and rental income all fall outside it. High earners almost always hold investment portfolios and property, so they need the Foreign Tax Credit for that income regardless. Running two systems side by side adds complexity and, as we will see, can actively waste relief.
The FTC usually eliminates the US charge on your pay and leaves extra credits because UK rates are higher than US rates. Under IRC §904, those excess credits carry back one year and forward up to ten years. That stored relief can shelter future US-taxable foreign income — a windfall bonus, a year working partly in the States, or foreign income the treaty lets the US tax. The exclusion generates no such reserve. For a deeper comparison, see our side-by-side on FTC vs FEIE.
Here is the trap. Every dollar you exclude under FEIE is a dollar the Foreign Tax Credit can no longer be claimed against, and the UK tax sitting on that excluded slice also vanishes from your credit pool. In a high-tax country, you are throwing away credits you would otherwise bank. Claiming the exclusion when the credit alone would have zeroed your bill is, for many, a straight loss — which is exactly why, for high earners, FTC, not FEIE, is the planning rule we apply first.
Elect the FEIE, then revoke it, and you cannot re-elect for five tax years without applying for IRS consent (and paying for a ruling). A choice that looks harmless in a low-earning year can trap you when your income — and your foreign tax — climbs. The credit carries no equivalent lock-in.
Meet Priya, a US citizen and creative director in London earning a £200,000 salary (roughly $254,000). She pays UK tax of about £68,000 (roughly $86,000) after the tapered allowance. Here is how the two routes compare on her 2026 US return.

The exclusion leaves Priya with residual US tax and nothing in reserve. The credit clears her US liability to zero and banks roughly $28,000 of surplus credits she can carry forward for up to ten years. The figures are illustrative and rounded, but the direction of travel is what matters, and it points one way. The demonstration that high-earners FTC, not FEIE, delivers the better outcome is rarely closer than this.
The Foreign Tax Credit is powerful but not total. It cannot be used against the 3.8% Net Investment Income Tax (NIIT), which applies to investment income above the threshold and is a separate charge with no foreign-tax offset. High earners with sizeable portfolios should budget for it. We cover planning around this in our piece on the 3.8% NIIT for expats. It is a leak to manage, not a reason to reach for the exclusion — the exclusion does nothing about NIIT either.
None of this makes FEIE useless. It shines in low-tax and no-tax jurisdictions — the Gulf states, Singapore for some, or anywhere you pay little or no local income tax — because there is barely any foreign tax to credit in the first place.
It can also help a lower earner whose income sits comfortably under the cap, or someone in a transitional year abroad. The point is not that the exclusion is bad; it is that it is the wrong tool for a high earner in a high-tax country like the UK. The full mechanics of both reliefs and the treaty that governs them are set out in the US-UK income tax treaty. For clients juggling several income streams, we usually model both methods before filing, as described in our note on how consultants avoid double taxation.
Getting the FEIE-versus-FTC decision right is worth thousands, and the wrong election can lock you out of the better route for five years.

Yes, but not on the same income. You could exclude your salary under FEIE and credit foreign tax on your investment income under the FTC. For most high earners in the UK, though, using the credit alone is cleaner and produces a lower US bill, because the exclusion removes income that the credit could otherwise shelter.
The stacking rule taxes the income above the exclusion at the rate that would have applied without the exclusion. So your top slice is taxed at your true marginal rate rather than from the bottom bracket up. That erodes the benefit precisely when your income is highest, which is a core reason the case for high earners FTC not FEIE holds so firmly in high-tax countries.
Unused credits carry back one tax year and forward up to ten. Because UK rates usually exceed US rates, high earners routinely build a bank of excess credits that can shelter future US-taxable foreign income, such as a bonus year or income that the treaty allows the US to tax.
Yes. The credit applies across income categories, including passive income such as dividends, interest, and capital gains, provided you have paid foreign tax on them. The exclusion, by contrast, applies only to earned income, such as salary and self-employment profits.
No. The Net Investment Income Tax is a separate charge, and no foreign tax credit can be applied against it. High earners with significant investment income should expect to pay NIIT even when the credit has cleared their regular US income tax to zero.
