FEIE vs. FTC Optimization Engine [2026] — Free Calculator to Find Your Best Strategy

The Short Answer — FEIE vs FTC in 30 Seconds

Here's the bottom line: the best strategy depends on your country and income.

What Is the Foreign Earned Income Exclusion (FEIE)?

The FEIE allows qualifying US expats to exclude a portion of foreign earned income from US taxable income — you simply don't pay US tax on that amount.

2026 FEIE Limit

• Single / MFS: $132,900
• MFJ (both qualify): $265,800
• MFJ (one qualifies): $132,900

Qualification Tests

Tax home requirement: Your tax home must be in the foreign country for the entire qualifying period.

Qualifying income: Earned income only (wages, salary, self‑employment). Does NOT include: pensions, interest, dividends, capital gains, rental income, alimony.

Foreign Housing Exclusion: Base amount $17,664 (single) / $21,600 (HOH); maximum exclusion $30,000 (single) / $38,400 (HOH). Use the Section 911 Housing Deduction Allocator to calculate your exact exclusion.

Form: Form 2555 attached to Form 1040.

What Is the Foreign Tax Credit (FTC)?

The FTC provides a dollar‑for‑dollar credit against US income tax for foreign income taxes paid. It reduces your US tax liability directly.

Form: Form 1116 attached to Form 1040.

Qualifying income: Earned income (no cap) and passive income (dividends, interest, rent, royalties, capital gains).

FTC baskets: Passive basket and General basket — calculated separately; cannot cross‑utilize credits.

Carryforward: 1 year back, 10 years forward.

No residency test required.

FEIE vs. FTC — Deep Dive Comparison

Key takeaway: FEIE is simpler and works well in low‑tax countries. FTC is more complex but more flexible — covers all income types and preserves credits and retirement account eligibility.

The Hybrid Strategy — Using Both FEIE and FTC

You can use both in the same tax year. Claim FEIE on earned income up to the $132,900 cap; claim FTC on earned income above the cap and on all passive income.

Critical rule — no double‑dipping: You cannot claim both on the same dollars of income.

Income Allocation Guide

Real Hybrid Example

Scenario: Single expat in Thailand with $160,000 earned income and $30,000 foreign taxes paid.

• FEIE portion: $132,900 excluded — US tax: $0
• FTC portion: Remaining $27,100 taxable — US tax before FTC: ~$1,135
• FTC claimed: $1,135 (limited to US tax on the taxable portion)
• Final US tax: $0 — FTC eliminates remaining liability
• Carryforward: $30,000 − $1,135 = $28,865 available for future years

The hybrid strategy saves $1,135 vs. FEIE‑only and preserves CTC and IRA eligibility.

Advanced Optimization Strategies for Expats

Foreign Housing Exclusion Stacking

Stack the Foreign Housing Exclusion on top of FEIE. For 2026: base amount $17,664 (single), max exclusion $30,000 (single). Combined limit: FEIE + Housing Exclusion ≤ $132,900 + max housing exclusion.

Example: London expat with $150,000 earned income and $35,000 qualifying housing expenses: FEIE $132,900 + housing exclusion $17,336 = $150,236 total exclusion.

FTC Basket Planning

Two baskets: Passive (dividends, interest, rent, capital gains) and General (wages, salary, self‑employment). Calculate credits separately — cannot cross‑utilize.

Multi‑Year Carryforward Strategy

Unused FTC credits carry forward 10 years. Use them for income smoothing, bracket management, and strategic timing.

State Tax Implications

FEIE and FTC apply to federal taxes only. Most states do not conform to FEIE; some allow FTC. Nine states have no income tax (AK, FL, NV, NH, SD, TN, TX, WA, WY).

How to File Your Tax Return — Step‑by‑Step Form Guidance

Step 1: Determine Your Strategy

• Use the calculator above to get your recommendation (FEIE‑only, FTC‑only, or Hybrid).

Step 2: Gather Documents

• W‑2 or 1099 forms, foreign tax receipts, passport (for Physical Presence Test), housing expense records.

Step 3: Fill Out Forms

• FEIE: Form 2555
• FTC: Form 1116
• Hybrid: both forms — allocate income correctly.

Step 4: Complete Form 1040

• Enter total income, standard deduction/itemized, FEIE exclusion, FTC credit, calculate final tax.

Step 5: File Before the Deadline

• April 15, 2026 (or June 15 if abroad with Form 4868 extension).

Partial‑Year Residency — What If You Move Mid‑Year?

• Physical Presence Test: Count days abroad — can still qualify if you meet 330‑day requirement within a 12‑month period.
• Bona Fide Residence Test: Must be a resident for a full tax year — may not qualify until the following year.
• FTC: No residency test — can claim credit for any foreign taxes paid while abroad.
• Hybrid: Combine FEIE (for the period you qualify) and FTC (for the rest).

Example: Move to UK on July 1, 2025, earn $100,000 July‑Dec, pay $20,000 UK tax. In 2026 you may qualify for FEIE for July‑Dec (330‑day test by July 2026) and FTC for UK taxes paid.

Consult a CPA for partial‑year calculations — this is a common area of error.

The 5‑Year FEIE Revocation Rule — What Nobody Tells You

What Happens When You Revoke FEIE

If you elect FEIE and then don't claim it in a future year, the IRS treats this as a revocation — even without a formal statement. Once revoked, you are barred from using FEIE for the next 5 tax years.

• Formal revocation (filing a statement)
• Deemed revocation (not claiming FEIE after having claimed it previously)
• Both Physical Presence and Bona Fide Residence claimants

Exception: The IRS may grant approval in cases of hardship, but approval is rare.

When Revocation Makes Sense

• Income significantly above $132,900
• High‑tax country where FTC eliminates all US tax
• Substantial passive income
• Need to preserve CTC or IRA eligibility

When to Keep FEIE Despite Higher Tax

• Plan to move to a low‑tax country in the next 5 years
• Income expected to drop below the FEIE cap
• Limited foreign tax paid in future years
• Value simplicity of FEIE (Form 2555 simpler than Form 1116)

How the FEIE vs FTC Optimization Engine Works

This calculator estimates your US tax liability under three strategies and compares the results.

Core Calculation Formula

• FEIE scenario: Taxable income = (earned income − FEIE exclusion) + passive income
• FTC scenario: Taxable income = earned income + passive income (no exclusion)
• Hybrid scenario: Taxable income = (earned income − FEIE exclusion up to cap) + passive income

Apply standard deduction: $15,750 (single) / $31,500 (MFJ). Calculate US tax using 2026 federal brackets (10%–37%). Apply FTC and CTC. Final tax = Max(0, US tax before credits − FTC − CTC).

Data Sources

• FEIE limits: IRS Revenue Procedure 2025‑24 (annual inflation adjustment for §911)
• Tax brackets: IRS 2026 tax rate schedules (Rev. Proc. 2025‑24)
• Standard deduction: IRS 2026 standard deduction amounts
• Form 2555 and Form 1116: IRS Form 2555 and Form 1116 (2026 versions)
• IRC §911 and §901 referenced and applied

What This Calculator Does NOT Do

• Substitute for professional tax advice
• Incorporate all possible deductions, credits, or special circumstances
• Calculate state taxes
• Handle complex scenarios like AMT, tax treaties, or multiple foreign tax jurisdictions
• Account for FEIE revocation timing beyond the basic 5‑year lockout warning
