The 2026 Expat Tax Guide: Navigating the $132,900 FEIE Limit and the Alternative Minimum Tax (AMT)

The 2026 inflation adjustment to the Foreign Earned Income Exclusion (FEIE)—now $132,900 per qualifying taxpayer—provides a measurable but limited tax shield for US citizens and lawful permanent residents earning income abroad. Combined with the structural changes introduced by the One Big Beautiful Bill Act (OBBBA), including a tightened Alternative Minimum Tax (AMT) phase-out regime targeting earners above $500,000, the strategic calculus for high-earning expats has shifted materially. Mechanical reliance on Form 2555, without coordinated Foreign Tax Credit (FTC) modelling, now exposes six- and seven-figure earners to avoidable AMT liability and forfeited treaty benefits. This briefing isolates the optimal filing posture for 2026 under current IRS guidance.

Maximizing the $132,900 FEIE Limit Under 2026 IRS Regulations

IRS Section 911 authorizes a qualifying US person abroad to exclude up to $132,900 of foreign earned income from federal taxable income for tax year 2026, claimed on Form 2555. A married couple in which both spouses qualify independently may exclude up to $265,800 in aggregate foreign-earned wages or self-employment income. The exclusion does not extend to passive income—dividends, interest, capital gains, rental income, or pension distributions—nor to compensation paid by the US government to its employees abroad.

Layered atop the base FEIE is the Foreign Housing Exclusion (employee) or Deduction (self-employed), which permits exclusion of qualified housing costs above 16% of the FEIE base (approximately $21,264 in 2026) up to a default ceiling of 30% of the FEIE (approximately $39,870), with materially higher caps for designated high-cost cities published in the annual IRS Notice. Together, these provisions can shield well over $170,000 of compensation in qualifying jurisdictions before any Foreign Tax Credit (FTC) is applied.

Qualifying Under the Physical Presence Test

The physical presence test is a mechanical day-count standard with no equitable exceptions:

• The taxpayer must be physically present in a foreign country or countries for 330 full 24-hour days during any consecutive 12-month period.
• Days of arrival into and departure from the United States generally do not count as foreign-presence days.
• International airspace and waters are not considered a “foreign country” presence.
• Travel days through a foreign country in transit may qualify if certain conditions under Treasury Regulation § 1.911-2(d) are met.
• The qualifying 12-month period need not align with the calendar year; partial-year Form 2555 elections are computed pro rata.

Qualifying Under the Bona Fide Residence Test

The Bona Fide Residence Test is a facts-and-circumstances determination available only to US citizens (and treaty-protected resident aliens):

• The taxpayer must establish a genuine residence in a foreign country for an uninterrupted period that includes a full tax year (January 1 to December 31).
• A statement to foreign tax authorities asserting non-residency for local tax purposes generally disqualifies the test.
• Brief returns to the United States are permitted if intent to return to the foreign tax home is demonstrable.
• The IRS evaluates housing arrangements, family location, community ties, banking relationships, and visa status holistically.
• Once established, the status persists across multiple years until affirmatively abandoned, simplifying recurring Form 2555 filings.

FEIE vs FTC: Strategic Election Under Form 2555 and Form 1116

The election between Form 2555 (FEIE) and Form 1116 (FTC) is jurisdiction-dependent and effectively binary on excluded income—amounts excluded under FEIE cannot simultaneously generate FTC carryforwards. The decision matrix below models a single filer earning $200,000 of foreign wages.

Senders earning materially above the $132,900 ceiling in high-tax jurisdictions almost universally optimize under the FTC, since foreign taxes paid above the US liability generate carry-forward credits that are useful in subsequent low-foreign-tax years. Conversely, expats in zero-tax jurisdictions extract greater absolute value from FEIE combined with the Foreign Housing Exclusion.

Alternative Minimum Tax (AMT) Exposure Under OBBBA

The One Big Beautiful Bill Act (OBBBA) preserved the elevated AMT exemption thresholds enacted under the Tax Cuts and Jobs Act but reintroduced an aggressive phase-out regime effective January 1, 2026. The phase-out now begins at $500,000 of alternative minimum taxable income for single filers and $1,000,000 for joint filers, with the exemption reduced at 50% per dollar above the threshold—double the prior 25% rate. For a married couple with $1,400,000 of alternative minimum taxable income in 2026, the AMT exemption is fully eliminated, exposing the entire base to the 26% and 28% alternative tax brackets.

For expats, the critical interaction is the FEIE stacking rule of IRS Section 911(f): income excluded under Form 2555 is restored to the base for purposes of computing the marginal rate on non-excluded income, which materially elevates AMT exposure for high earners. Foreign Tax Credit users on Form 1116 retain a separate AMT FTC computation that frequently produces a more favorable result, reinforcing the FTC preference for taxpayers in high-tax jurisdictions and for those approaching the new OBBBA phase-out thresholds.

Tax Home, Double Taxation Treaty Coordination, and Tax Equalization

Establishing a tax home outside the United States is a non-waivable prerequisite for both qualification tests under IRS Section 911. The tax home is the location of the taxpayer’s regular or principal place of business; absent such a place, it is the regular place of abode. Maintaining a US residence available for personal use throughout the year frequently invalidates the foreign tax home assertion.

Where the host country has a double taxation treaty with the United States—67 active treaties as of 2026—taxpayers may invoke tie-breaker provisions, reduced withholding rates on passive activity income, and totalization agreement coverage for Social Security. Treaty-based positions inconsistent with Form 2555 must be disclosed on Form 8833, and certain treaty articles preserve the right of the United States to tax its citizens regardless of treaty residency status (the “saving clause”).

Corporate expats should evaluate tax equalization policies carefully. Under standard tax equalization, the employer guarantees the assignee a net tax position equivalent to the home-country baseline, with the employer absorbing host-country tax in excess. The hypothetical tax retained from gross compensation is itself foreign earned income for Form 2555 purposes, expanding FEIE utility, while employer-paid foreign income tax remains creditable on Form 1116.

Filing Strategy: Standard Deduction, Passive Activity Loss, and 2026 Compliance

Expats claiming the FEIE retain the standard deduction—$15,750 for single filers and $31,500 for joint filers in 2026—against any non-excluded US-source or unexcluded foreign-source income. Passive activity loss rules under IRC Section 469 continue to suspend disallowed rental and limited-partnership losses, with carry-forward release on full disposition; expats holding US rental real estate during foreign assignment should model whether material-participation status remains achievable across time zones.

The fiduciary-aligned 2026 filing posture is sequential: confirm tax home and qualification test, model FEIE versus FTC for the specific jurisdiction, project AMT exposure under the new OBBBA phase-out, and finalize the Form 2555 versus Form 1116 election before any 5-year lockout under Section 911(e) is triggered. Coordinated execution preserves both current-year tax efficiency and the optionality required for multi-year career mobility.
