The AMT Trap: Why High Earners Using FEIE Get Surprise Tax Bills

Here's a scenario I see more often than I'd like: a high-earning expat claims the Foreign Earned Income Exclusion, expects to owe nothing, and then gets hit with a tax bill anyway.

The culprit? The Alternative Minimum Tax (AMT).

If you earn over $200,000 abroad, you need to understand this trap before it catches you.

What Is the Alternative Minimum Tax?

The AMT is a parallel tax system designed to ensure high-income taxpayers pay at least a minimum amount of tax, regardless of deductions and exclusions.

It works like this:

1. Calculate your regular tax liability
2. Calculate your AMT liability (using different rules)
3. Pay whichever is higher

The AMT has its own set of rates (26% and 28%) and its own exemption amount. Crucially, it treats some things differently than regular tax — including the FEIE.

Why the FEIE Triggers AMT Problems

Here's the trap: the AMT does not recognize the Foreign Earned Income Exclusion the same way regular tax does.

Under regular tax rules, when you exclude income with the FEIE, it's as if that income doesn't exist. Your remaining income is taxed starting at the lowest brackets.

Under AMT rules, the excluded income is added back when calculating your AMT liability. This pushes you into higher AMT brackets and can phase out your AMT exemption.

A Simplified Example

Sarah earns $250,000 working in Singapore:

Regular Tax Calculation:

• Gross income: $250,000
• FEIE exclusion: -$132,900
• Taxable income: $117,100
• Regular tax: ~$20,000

AMT Calculation:

• Gross income for AMT purposes considers the excluded amount
• AMT exemption phases out at higher incomes
• AMT liability: ~$35,000

Result: Sarah owes the higher amount — $35,000, not $20,000.

She used the FEIE thinking she'd minimize her taxes, but the AMT ate those savings.

Who's at Risk?

You're most vulnerable to the AMT trap if:

• Your foreign earned income exceeds $200,000
• You live in a low-tax or no-tax country (UAE, Singapore, Bahamas)
• You have significant itemized deductions that get disallowed under AMT
• You have incentive stock options (ISOs) or other AMT preference items
• You're married filing separately (lower AMT exemption)

The higher your income and the lower your foreign taxes paid, the more likely the AMT will bite.

The Numbers for 2026

For tax year 2026, the AMT exemption amounts are approximately:

When your AMT income (which includes the FEIE-excluded income for exemption phase-out purposes) exceeds the phase-out threshold, you lose $0.25 of exemption for every $1 over the threshold.

How to Check If You're Affected

Before filing, run the numbers both ways:

1. Calculate with FEIE: Use Form 2555, claim the exclusion, then calculate Form 6251 (AMT)
2. Calculate with Foreign Tax Credit: Skip the FEIE, claim the FTC on Form 1116 instead

Compare the total tax liability under each scenario.

Tax software usually handles this automatically, but it's easy to miss the warning signs if you're not looking.

Strategies to Minimize the AMT Trap

1. Use the Foreign Tax Credit Instead

If you live in a country with meaningful income taxes (Germany, UK, France, Australia), the Foreign Tax Credit often works better for high earners.

The FTC gives you a dollar-for-dollar credit for foreign taxes paid. If you're paying 30% in foreign taxes, you likely won't owe U.S. tax under either system — but the FTC avoids AMT complications.

2. Use a Combination Strategy

You're allowed to use the FEIE for wages up to the exclusion amount AND the FTC for taxes paid on income above the exclusion.

Example:

• Earn $250,000
• Exclude $132,900 with FEIE
• Pay foreign taxes on remaining $117,100
• Claim FTC for those foreign taxes

This can sometimes give you the best of both worlds, but run the numbers carefully.

3. Time Your Income

If you have control over when you receive income (bonuses, consulting payments), you may be able to shift income between years to stay below AMT thresholds.

This requires advance planning and isn't always possible, but it's worth considering.

4. Accelerate or Defer Deductions

Certain deductions are disallowed under AMT (state and local taxes, miscellaneous itemized deductions). If you're on the AMT bubble, adjusting the timing of deductible expenses might help.

5. Consider Revocation (Carefully)

If the FEIE consistently triggers AMT, you might consider revoking your FEIE election and switching entirely to the Foreign Tax Credit.

Warning: Once you revoke the FEIE, you generally can't re-elect it for five years without IRS approval. Don't make this decision lightly.

Case Study: When FEIE Backfires

Michael's situation:

• Works for a tech company in Dubai (no income tax)
• Earns $280,000 in salary
• Single, no other significant income

With FEIE:

• Excludes $132,900
• Remaining $147,100 subject to U.S. tax
• But AMT kicks in due to high income and no foreign tax credits
• Total U.S. tax: approximately $45,000

With Foreign Tax Credit:

• No foreign taxes paid (Dubai has no income tax)
• Full $280,000 subject to U.S. tax
• No AMT because no FEIE-related add-backs
• Total U.S. tax: approximately $55,000

In Michael's case, the FEIE is still better — but not by as much as he expected. The AMT ate into his savings significantly.

Alternative approach: Michael could consider relocating to a country with income taxes (Portugal, Spain) where the FTC would eliminate most U.S. liability without AMT complications.

When to Get Help

The AMT interaction with the FEIE is one of the most complex areas of expat taxation. If any of these apply to you, consider professional guidance:

• Income over $200,000
• Living in a no-tax or low-tax country
• Stock compensation or incentive stock options
• Significant investment income alongside earned income
• Multiple years of excess foreign tax credits

The cost of planning is usually far less than an unexpected tax bill.

The Bottom Line

The Foreign Earned Income Exclusion is a powerful tool, but it's not always the best choice. For high earners, especially those in low-tax countries, the Alternative Minimum Tax can claw back much of the FEIE's benefit.

Before you automatically claim the FEIE, run the numbers. Compare it to the Foreign Tax Credit. And if you're in AMT territory, plan proactively rather than getting surprised at filing time.

The math is complex, but the principle is simple: test both options before you file.
