Most US expats default to the Foreign Earned Income Exclusion because it sounds like 'tax-free up to the threshold.' For a lot of UK-based Americans — especially anyone earning above the FEIE cap, with UK pension contributions, or planning a return to the US — Foreign Tax Credits leave you materially better off and preserve carry-forwards. The decision compounds: once you elect FEIE, revoking it locks you out for five years.
