Tax Q&A in category: Foreign Earned Income & Exclusions

Q: Can I claim the Foreign Earned Income Exclusion on a part-time or side income I earn abroad?

Yes. The Foreign Earned Income Exclusion ( FEIE) applies to part-time, side-hustle, and gig income earned for services performed abroad, as long as you qualify under either the Physical Presence Test or the Bona Fide Residence Test . The FEIE does not require full-time employment or a specific occupation. Qualifying part-time and side income scenarios: Freelance writing, design, coding, or consulting performed from your foreign residence Part-time employment with a foreign or U.S. employer for work performed abroad Side business selling products or services performed while physically abroad Teaching English, tutoring, or online instruction delivered from abroad Content creation (YouTube, Substack, Patreon), where services are performed abroad Rules to keep in mind: Income must be from services performed in a foreign country; client or platform location does not matter Total exclusion cap of Annual FEIE exclusion / $132,900 (2026) applies across all earned income Self-employment part-time income still owes 15.3% SE tax (FEIE does not reduce it) Hobby income (activity not pursued for profit) does not qualify as earned income and does not get FEIE relief What to track: Income received per platform or client Dates and location of services performed Physical presence documentation to pass the test For side-hustlers planning ahead, the FTC sometimes beats the FEIE because side-hustle income is often small relative to the exclusion cap, and the FTC preserves retirement contribution capacity.

Question 1

Does passive income, rental income, or Social Security count toward the FEIE?

Accepted Answer

The Foreign Earned Income Exclusion (FEIE) covers foreign-earned compensation for personal services performed abroad, including wages, salary, professional fees, self-employment income, and cash-value fringe benefits. Passive income, pensions, Social Security, and U.S.-source compensation do not qualify regardless of where you live.

What qualifies as foreign-earned income:

Wages and salaries for work performed while physically in a foreign country
Self-employment net earnings from services performed abroad
Professional fees (consulting, freelance, creative services)
Commissions and bonuses earned for foreign services
Tips from foreign service
Cash-value benefits: housing allowances, cost-of-living adjustments, education allowances, car allowances

What does not qualify: Income typeFEIE?Interest and dividendsNoCapital gainsNoRental incomeNoPensions and annuitiesNoU.S. Social Security benefitsNoRoyalties (usually passive)Generally noCompensation paid by the U.S. governmentNoIncome earned in international waters or airspaceNoU.S.-source wages (work performed in the U.S.)No Limits and caps:

$130,000 exclusion per qualifying person for tax year 2025
$132,900 for 2026
Married couples each claim separately if both qualify, doubling to $260,000 (2025)
Foreign Housing Exclusion stacks on top for housing expenses above a base amount

Elections and revocation:

FEIE is elected on Form 2555 attached to Form 1040
Once elected, exclusion continues automatically until revoked
Revocation locks you out for 5 years unless IRS consent is obtained

For more on qualifying income, see our Foreign Earned Income Exclusion.

Question 2

How many U.S. days can I spend per year without triggering resident tax status?

Accepted Answer

As a general rule, staying under 121 U.S. days per year keeps you below the Substantial Presence Test (SPT) threshold when averaged over three years, avoiding U.S. resident tax status. The exact limit depends on your travel pattern across the current year and the two prior years, because the IRS weights older days at reduced rates.

The IRS applies a three-year weighted formula requiring both:

At least 31 days of U.S. presence in the current year, AND
183 or more weighted days across the current year (100%), the prior year (1/3), and the second prior year (1/6)

Planning your annual day budget: Travel patternCurrent year daysPrior year days2nd prior year daysWeighted totalSPT triggered?Even split121121121121 + 40 + 20 = 181NoFront-loaded1509060150 + 30 + 10 = 190YesBack-loaded9015018090 + 50 + 30 = 170No What counts as a day of presence:

Any part of a day in the U.S. counts as a full day (even a layover)
Exceptions: transit under 24 hours on international travel, medical emergencies, F/J/M/Q visa-exempt individuals for limited years, and A/G visa holders

If you’ve already crossed the threshold:

Closer Connection Exception (Form 8840): available if you were in the U.S. fewer than 183 days this year and maintain a tax home and closer connection to a foreign country
Treaty tiebreaker (Form 8833): claim foreign residency under a bilateral tax treaty

Track your U.S. days year-round. Once you pass the SPT, you are taxed on worldwide income like a U.S. citizen, and unwinding that status mid-year is complex.

For the full test details and calculator, see our Substantial Presence Test.

Question 3

Can I claim the Foreign Earned Income Exclusion on a part-time or side income I earn abroad?

Accepted Answer

Yes. The Foreign Earned Income Exclusion( FEIE) applies to part-time, side-hustle, and gig income earned for services performed abroad, as long as you qualify under either the Physical Presence Test or the Bona Fide Residence Test. The FEIE does not require full-time employment or a specific occupation.

Qualifying part-time and side income scenarios:

Freelance writing, design, coding, or consulting performed from your foreign residence
Part-time employment with a foreign or U.S. employer for work performed abroad
Side business selling products or services performed while physically abroad
Teaching English, tutoring, or online instruction delivered from abroad
Content creation (YouTube, Substack, Patreon), where services are performed abroad

Rules to keep in mind:

Income must be from services performed in a foreign country; client or platform location does not matter
Total exclusion cap of Annual FEIE exclusion / $132,900 (2026) applies across all earned income
Self-employment part-time income still owes 15.3% SE tax (FEIE does not reduce it)
Hobby income (activity not pursued for profit) does not qualify as earned income and does not get FEIE relief

What to track:

Income received per platform or client
Dates and location of services performed
Physical presence documentation to pass the test

For side-hustlers planning ahead, the FTC sometimes beats the FEIE because side-hustle income is often small relative to the exclusion cap, and the FTC preserves retirement contribution capacity.

For more on part-time expat filing, see our Self-Employment Tax for Expats.

Question 4

Can I use the FEIE retroactively if I forgot to claim it on a prior year return?

Accepted Answer

Yes. You can claim the Foreign Earned Income Exclusion (FEIE) retroactively by filing an amended return (Form 1040-X) for any year still within the statute of limitations, which is generally 3 years from the original filing deadline (or 2 years from when the tax was paid, whichever is later).

Amending to add FEIE:

File Form 1040-X for the year you want to amend
Attach Form 2555 with the FEIE election and supporting tests
Note in Part III of Form 1040-X that you are claiming FEIE
File by paper (amended returns are increasingly e-filable, but FEIE amendments often still require mail)

Timeframes: ScenarioAvailable windowReturn filed on time3 years from original due dateRefund claim3 years from filing, or 2 years from tax paid (later)Return not filed at allDelinquent return with FEIE via SFOP if non-willful Conditions and caveats:

FEIE must apply to foreign earned income, and you must have qualified under one of the tests in that year
Election to claim FEIE is revocable only with IRS consent once made
Amending after a refund has been received and spent is still allowed; adjustments flow through as normal

Common scenarios:

Newly discovered you were an accidental American and need to file multiple years (SFOP is often the right path, not 1040-X)
DIY software missed the FEIE election in a prior year
CPA overlooked the option on a return filed in a rush

For catch-up and amendment guidance, see our Streamlined Filing Compliance Procedures guide.

Question 5

How do I reduce U.S. tax on foreign investment income that the FEIE doesn't cover?

Accepted Answer

The Foreign Earned Income Exclusion covers only earned income from personal services. For foreign investment income such as dividends, interest, rental income, and capital gains, the Foreign Tax Credit (FTC) on Form 1116 is your primary relief tool, and smart basket planning can eliminate or sharply reduce U.S. tax on that income.

FTC strategy by passive income type: Income typeForeign tax is usually paidFTC basketKey planning moveForeign dividendsWithholding (often 15-30%)PassiveTreaty may reduce withholding to 15% or lowerForeign interestWithholding variesPassiveSome treaties exempt interest entirelyForeign rental incomeIncome tax in country of propertyGeneral or passiveNet-basis election abroad mirrors U.S. Schedule E treatmentForeign capital gainsVaries widely by countryPassive or generalTiming of sale can align high-tax year with FTC availabilityForeign pensionsIncome tax at distributionGeneralTreaty may exempt or reduce source-country tax Reducing the gap beyond FTC:

Treaty withholding reductions: file the appropriate treaty form (e.g., W-8BEN equivalent in the foreign country) to reduce withholding at source before it hits your FTC calculation
Basket management: passive-basket credits cannot offset general-basket tax. Keep passive income and general income tracked separately to avoid stranded credits.
Excess credit carryforward: unused passive-basket FTCs carry forward for up to 10 years. A high-tax year abroad can generate credits that offset U.S. tax in a future low-tax year.
Net Investment Income Tax (NIIT): the 3.8% surtax on net investment income above $200,000 (single) or $250,000 (MFJ) does not currently allow FTC offset, though proposed regulations have addressed this. Track separately.

Question 6

Do I lose the FEIE if I return to the U.S. for more than 35 days in the year?

Accepted Answer

It depends on which test you use. If you rely on the Physical Presence Test, spending more than 35 days in the U.S. during any 12-month period disqualifies you. If you qualify under the Bona Fide Residence Test, there is no 35-day cap, though extended U.S. stays can undermine your claim of bona fide foreign residency.

Physical Presence Test (PPT):

Requires 330 full days in foreign countries during a 12-month period
Any day partially in the U.S. counts as a U.S. day
35-day U.S. budget (365 – 330 = 35)
Exceeding the budget disqualifies you for that 12-month window

Bona Fide Residence Test (BFR):

Requires bona fide residence in a foreign country for an entire tax year
No specific day cap, but extended U.S. stays undermine bona fide residence
IRS considers: housing, family ties, social ties, employment, intent to remain

Planning options when you approach 35 U.S. days:

Shift the 12-month window to different start and end dates
Switch to Bona Fide Residence Test if you qualify (requires full tax year as foreign resident)
Split strategy: PPT for the first qualifying window, BFR for the second year
Use Foreign Tax Credit instead of FEIE (no day count)

Any trip to the U.S. should be tracked and counted from arrival to departure.

For more on managing U.S. days, see our Foreign Earned Income Exclusion guide.

Question 7

How do I stop my U.S. employer from withholding federal tax on wages I plan to exclude with the FEIE?

Accepted Answer

File Form 673 (Statement for Claiming Exemption from Withholding on Foreign Earned Income Eligible for the Exclusion) with your U.S. employer to stop federal income tax withholding on wages you expect to exclude under the Foreign Earned Income Exclusion. Without it, your employer withholds at normal rates, and you wait until filing to claim a refund.

How Form 673 works:

You certify that you expect to qualify under either the Physical Presence Test or the Bona Fide Residence Test
Your employer stops withholding federal income tax on wages up to the FEIE cap ($130,000 for 2025)
The form does not stop FICA (Social Security + Medicare) withholding, which continues unless a totalization agreement applies
It does not stop state withholding, which requires a separate state-specific process

When to file Form 673 vs. adjust your W-4: ApproachBest forEffectForm 673Employees who qualify for FEIE and want to stop federal withholding entirelyEmployer exempts FEIE-eligible wages from federal income tax withholdingW-4 adjustmentEmployees who want to reduce (not eliminate) withholdingLower withholding based on expected credits/deductionsNeither (claim refund at filing)Employees uncertain about qualifyingOverpay during the year, claim refund on Form 1040 with Form 2555 Risks to manage:

If you fail to qualify for the FEIE (e.g., return to the U.S. early and miss the 330-day threshold), you owe the full tax plus potential underpayment penalties
If your income exceeds the FEIE cap, the excess is still subject to U.S. tax and should have estimated payments or W-4 withholding
Form 673 must be renewed each year; it does not carry forward automatically

Question 8

Can I contribute to a Roth IRA or traditional IRA if I claim the Foreign Earned Income Exclusion?

Accepted Answer

It depends on whether your earned income exceeds the Foreign Earned Income Exclusion cap. IRA contributions require taxable compensation, and the FEIE reduces your taxable compensation dollar-for-dollar. If the FEIE covers all your earned income, your taxable compensation drops to zero, and you cannot contribute to a Roth IRA or traditional IRA for that year.

How the math works: ScenarioEarned incomeFEIE claimedTaxable compensationIRA eligible?Income below FEIE$90,000$90,000$0NoIncome above FEIE$160,000$130,000$30,000Yes (up to $7,000 / $8,000 if 50+)Partial FEIE$135,000$130,000$5,000Yes (up to $5,000)FTC instead of FEIE$90,000$0$90,000Yes

Roth IRA income limits still apply on top of the compensation requirement. For 2025, the phase-out begins at $150,000 MAGI (single) or $236,000 (MFJ). Your MAGI for Roth purposes adds back excluded income, which can push you over the limit even with low taxable income.

Strategies to preserve IRA eligibility:

Use the Foreign Tax Credit instead of FEIE: FTC does not reduce taxable compensation. In high-tax countries, FTC often produces the same tax result while keeping IRA doors open.
Claim partial FEIE: exclude only enough income to reduce your tax bill, leaving taxable compensation for IRA contributions
Employer-sponsored plans: 401(k) and 403(b) contributions are not affected by FEIE if your employer offers them
HSA contributions: require a qualifying HDHP, which most expats lose when moving abroad

This is one of the most common reasons expats choose FTC over FEIE, even when both produce similar tax outcomes.

For the FEIE vs FTC strategy, see our FEIE vs Foreign Tax Credit.

Question 9

What happens to my FEIE if I change countries in the middle of the tax year?

Accepted Answer

Changing countries mid-year does not break your Foreign Earned Income Exclusion (FEIE). Under the Physical Presence Test, your 330 foreign days can be spent in any combination of foreign countries. Under the Bona Fide Residence Test, continuous foreign residency (in one country or across multiple) can maintain eligibility, though the transition requires care.

Physical Presence Test and country changes:

Days in any foreign country count toward the 330
Transit days through the U.S. count as U.S. days
International waters or airspace do not count as foreign
Pick a 12-month window that maximizes foreign days across the two countries

Bona Fide Residence Test and country changes:

A clean transition from one foreign country to another may preserve BFR
An interruption where you return to the U.S. for more than a brief vacation may break BFR
You need bona fide residency in a foreign country throughout the tax year (no requirement that it be the same country)

Filing mechanics for mid-year country changes:

Form 2555 asks for the country of bona fide residence or the country used for PPT
Use a single 12-month window for PPT that straddles the two countries
If BFR was established in Country A and you moved to Country B mid-year, detail both in Part II (BFR) of Form 2555
Foreign tax paid to both countries goes on Form 1116 (FTC) as needed

Practical country-change scenarios:

UK to Spain in July: PPT counting days in both works well for the first year; BFR resumes after a full tax year in Spain
Mexico to Portugal in March: Similar PPT treatment; BFR in Portugal starts after a full tax year of bona fide residency

For multi-country FEIE planning, see our Foreign Earned Income Exclusion guide.

Question 10

Can my spouse and I each claim the full FEIE if we both qualify?

Accepted Answer

The Foreign Earned Income Exclusion limit for the 2025 tax year is $130,000 per qualifying individual, per the IRS inflation adjustment. Married couples in which both spouses qualify under the Physical Presence Test or Bona Fide Residence Test can each claim the full $130,000, excluding up to $260,000 in combined U.S. federal income tax.

What the FEIE limit covers:

$130,000 cap (2025 tax year) on foreign wages, salary, and self-employment earned income
Per-person limit, not per-household, so each qualifying spouse claims their own
Prorated if you qualified for only part of the year
Applies to income earned while your tax home is abroad and you meet PPT or BFR

Year-over-year comparison: Tax YearFEIE LimitIncrease from previous year2025$130,000$3,5002026$132,900$2,900 Additional exclusions stacked on the FEIE:

Foreign Housing Exclusion: qualifying housing costs above the base amount (16% of FEIE, or roughly $20,800 for 2025), up to a city-specific cap
Foreign Tax Credit: available on income above the FEIE or on excluded income categories

Filing mechanics for 2026:

Claim on Form 2555 attached to your 2025 Form 1040 (filed in 2026)
Meet the 12-month PPT window or bona fide residence for all of 2025
Self-employment income qualifies for the FEIE but remains subject to U.S. self-employment tax unless a totalization agreement applies

For the full FEIE strategy, see our Foreign Earned Income Exclusion.

Question 11

How do I report the Foreign Earned Income Exclusion on the FAFSA?

Accepted Answer

The FAFSA adds your Foreign Earned Income Exclusion (FEIE) amount back into your income for financial aid calculations. When FAFSA asks for “foreign earned income exclusion,” enter the amount from Form 2555 Line 45 (or Line 50 for the housing exclusion). This increases your reported income and can significantly reduce your child’s financial aid eligibility.

Where to find the number:

Form 2555, Line 45: your foreign earned income exclusion amount (up to $130,000 for 2025)
Form 2555, Line 50: your foreign housing exclusion amount (if claimed)
Add both together for the FAFSA entry
If you did not claim the FEIE, enter $0

Why FAFSA adds the exclusion back:

The FEIE reduces your Adjusted Gross Income on Form 1040
FAFSA treats this as untaxed income and adds it back to create a more complete picture of your family’s financial capacity
The result: your Student Aid Index (SAI) reflects your full earning power, not just the portion taxed by the U.S.

Impact on financial aid: Family income scenarioAGI on 1040FEIE add-backFAFSA total income$150,000 earned abroad, full FEIE$20,000$130,000$150,000$90,000 earned abroad, full FEIE$0$90,000$90,000$180,000, partial FEIE$50,000$130,000$180,000 Planning considerations for expat families:

FTC vs FEIE: switching to the Foreign Tax Credit does not avoid the add-back. FTC income is reported directly on AGI, so the FAFSA total is similar either way.
CSS Profile: Many private universities use the CSS Profile, which has its own treatment of foreign income. Check each school’s requirements separately.
IRS Data Retrieval Tool: expat returns sometimes fail automatic data transfer. Be prepared to enter FAFSA data manually and upload tax documents.

For more on the mechanics of FEIE, see our Foreign Earned Income Exclusion guide.

Question 12

Why is my U.S. tax rate higher than expected after claiming the Foreign Earned Income Exclusion?

Accepted Answer

The FEIE stacking rule is the reason. When you exclude income under the Foreign Earned Income Exclusion, the IRS does not let your remaining taxable income start at the lowest tax brackets. Instead, it is taxed at the rate it would have occupied if you had not excluded anything. This means your first taxable dollar above the exclusion is taxed at the 22% or 24% bracket, not at 10%.

How the stacking rule works:

Example: You earn $180,000 and exclude $130,000 via FEIE. Your taxable income is $50,000.

Without stacking (incorrect)With stacking (how the IRS calculates)First $11,925 at 10% = $1,193Tax on $180,000 = $35,498Next $36,550 at 12% = $4,386Minus tax on $130,000 = $21,538Remaining $1,525 at 22% = $336Tax owed = $13,960Total = $5,915Effective rate on $50,000 = 27.9%

The difference is significant: $13,960 vs $5,915 on the same $50,000 of taxable income.

Why the IRS does this:

Without stacking, every FEIE claimant would get the benefit of the lowest brackets twice: once through exclusion, once through reduced taxable income
The stacking rule under IRC Section 911(d)(6) preserves the progressive rate structure
Form 1040 Tax Computation Worksheet in the instructions walks through the calculation

When stacking hurts the most:

Income moderately above the FEIE cap: the remaining income lands entirely in the 22-32% brackets
Capital gains on top of excluded income: long-term gains brackets also stack (0% bracket starts higher)
Self-employment tax: SE tax is separate and not affected by stacking, but combined with the stacking rate, total effective rates can surprise you

Strategies to manage the stacking effect:

Foreign Tax Credit instead of FEIE: FTC does not trigger stacking because no income is excluded. In high-tax countries, the FTC often results in a lower total tax burden.
Partial FEIE: exclude less than the full cap to keep some income in lower brackets (useful when foreign tax rates are low and the stacking penalty exceeds the FEIE benefit)
Income timing: defer bonuses or capital gains to a year when total income is closer to the FEIE cap

For FEIE vs FTC planning, see our FEIE vs Foreign Tax Credit.

Question 13

Does the FEIE apply to stock options, RSUs, or equity compensation I receive while living abroad?

Accepted Answer

It depends on where you performed the services that earned the equity. The Foreign Earned Income Exclusion treats equity compensation as earned income, but only the portion allocable to services performed in a foreign country qualifies for exclusion. If the grant was earned partly in the U.S. and partly abroad, you must split it.

How the IRS sources equity compensation: Equity typeTaxable eventSourcing methodRestricted Stock Units (RSUs)Vesting dateDays worked abroad during grant-to-vest period / total work daysNon-Qualified Stock Options (NQSOs)Exercise dateDays worked abroad during grant-to-exercise period / total work daysIncentive Stock Options (ISOs)Sale date (for AMT: exercise date)Days abroad during grant-to-exercise for AMT; sale may be capital gainEmployee Stock Purchase Plan (ESPP)Sale dateDays abroad during offering period / total days in offering period

Example: You receive an RSU grant while working in the U.S. Two years later, it vests while you live in the UK. Of the 500 days between grant and vest, 300 were in the UK.

Foreign-source portion: 300/500 = 60% of vest value
That 60% qualifies for FEIE (subject to the $130,000 annual cap across all earned income)
The remaining 40% is U.S.-source and does not qualify

Common traps:

Large vest events can blow through the FEIE cap: a $200,000 RSU vest plus $150,000 salary means $350,000 of earned income competing for $130,000 of exclusion
FTC may be better: the Foreign Tax Credit applies to the foreign tax on equity income without a dollar cap, making it preferable in many equity-heavy situations
Double taxation risk: some countries tax equity at grant, others at vest, others at sale. Misalignment with U.S. timing creates complex FTC calculations
ISOs and AMT: the AMT preference item on ISO exercise is sourced the same way, and the FEIE stacking rule can push AMT liability higher

If you’re a Corporate Expat with equity compensation, Greenback can help you source grants correctly and choose between FEIE and FTC for the best result.

Question 14

How Does the FEIE Affect Student Loan Repayment for Expats?

Accepted Answer

The FEIE reduces your adjusted gross income, which directly lowers your monthly payment under income-driven repayment (IDR) plans like SAVE, PAYE, and IBR. If the FEIE excludes all your earned income, your AGI drops to $0, and your IDR payment drops to $0 as well, even if you earn $130,000 abroad (Federal Student Aid: Income-Driven Repayment Plans).

FEIE + IDR: AGI-based calculation means $0 AGI = $0 monthly payment
FEIE + PSLF: qualifying $0 payments count toward the 120-payment requirement if you work for a qualifying employer abroad (nonprofit, government, international organization)
FEIE + FAFSA: excluded income is added back as untaxed income on the FAFSA, so your Expected Family Contribution may not decrease
FTC alternative: FTC does not reduce AGI, so IDR payments stay higher, but IRA contribution eligibility is preserved

StrategyAGI ImpactIDR PaymentIRA Eligible?FEIE, $130K income$0$0/monthNo (no compensation)FTC, $130K income$130,000~$800-$1,200/monthYesPartial FEIE, $130K incomeVariesProportionalPartial PSLF for expats abroad:

Qualifying employers: U.S. government, 501(c)(3) nonprofits, and certain international organizations (World Bank, UN, IMF)
Foreign employers generally do not qualify unless they are a U.S. nonprofit operating abroad
$0 payments count: each $0 IDR payment while employed by a qualifying employer counts as one of the 120 required payments

Recertification from abroad: submit your IDR recertification annually using your U.S. tax return. If you e-file, the process works the same from any country.

For more, see our Foreign Earned Income Exclusion guide.

Question 15

What Is the FEIE Stacking Rule and How Does It Affect My Tax Bracket?

Accepted Answer

The FEIE stacking rule means that income above the $130,000 exclusion (2025 Tax Year) is taxed at the rate that would apply if the excluded income were still in the calculation. Your first dollar above the exclusion is not taxed at 10%. It is taxed at whatever bracket the excluded income pushed you into, typically 22% or 24% (IRS: Foreign Earned Income Exclusion).

How stacking works: IncomeWithout FEIEWith FEIE + StackingFirst $11,92510%Excluded (FEIE)$11,926 – $48,47512%Excluded (FEIE)$48,476 – $103,35022%Excluded (FEIE)$103,351 – $130,00024%Excluded (FEIE)$130,001 – $197,30024%Taxed at 24% (stacking)$197,301+32%Taxed at 32% (stacking)

Example: An expat earning $180,000 excludes $130,000 under the FEIE. The remaining $50,000 is taxed as if it were dollars $130,001 through $180,000, landing in the 24% bracket. Without stacking, that $50,000 would start at 10% and produce roughly $5,500 in tax. With stacking, it produces roughly $12,000 in tax.

Where the stacking rule appears: the IRS Form 1040 instructions include the “Foreign Earned Income Tax Worksheet” for line 16. This worksheet automatically applies the stacking calculation.

When stacking does NOT apply:

Long-term capital gains and qualified dividends are taxed at preferential rates (0%, 15%, 20%) and are not subject to the stacking rule
FTC users do not face stacking because the FTC does not exclude income from the bracket calculation
Self-employment tax is calculated on Schedule SE without regard to stacking

For more, see our FEIE vs Foreign Tax Credit.

Question 16

Can I claim the Foreign Earned Income Exclusion if my 330 days abroad span two different calendar years?

Accepted Answer

Yes, the Physical Presence Test uses any 12-month period, not the calendar year. When your 330 qualifying days span two calendar years, you pro-rate the FEIE between the two tax years based on the number of qualifying days falling in each year.

How pro-ration works:

Pick the best 12-month window that gives you 330+ foreign days
For each tax year, count the qualifying days falling in that year
Multiply the FEIE cap for that year by (qualifying days in year / 365)

Example: you left the U.S. on April 1, 2025, and stayed abroad through the end of 2026. A 12-month window of April 1, 2025, to March 31, 2026, gives you:

2025 pro-rata: 275 days (Apr 1 to Dec 31) / 365 × $130,000 = $97,945
2026 pro-rata: 90 days (Jan 1 to Mar 31) / 365 × $132,900 = $32,770

If you qualify for a second 12-month window in 2026 (e.g., Jan 1 to Dec 31, 2026, fully abroad), the full $132,900 becomes available for 2026 instead of the prorated $32,770.

Filing mechanics:

Form 2555 requires you to declare the 12-month window used
Form 2350 can extend the filing deadline if you need more time to accumulate qualifying days
You can claim different windows in different years to optimize

Housing exclusion pro-rates the same way based on qualifying days.

For FEIE strategy across partial years, see our Foreign Earned Income Exclusion.

Question 17

Can I claim both the Foreign Tax Credit and the Foreign Earned Income Exclusion?

Accepted Answer

Yes, you can claim both the FEIE and the Foreign Tax Credit in the same year, but not on the same income. The FEIE excludes foreign-earned income up to the annual cap (a maximum of $130,000 in 2025), and the Foreign Tax Credit (Form 1116) can offset U.S. tax on earnings above the exclusion or on unearned income like dividends, interest, or rental income.

How the two stack: Income bucketTreatmentForeign wages up to Annual FEIE exclusionExcluded via FEIEForeign wages above $130,000Taxable at U.S. rates, FTC availableForeign passive income (interest, dividends, rental)FTC in passive categoryForeign pensionFTC in general category (or passive depending on structure)Income taxed by foreign country but not U.S.-sourceFTC on U.S. tax of that income (subject to FTC limitation) Important mechanics:

Stacking the Foreign Housing Exclusion with FEIE adds another layer of shelter before the FTC applies
Stacking rule under Section 904: FTC on the non-excluded portion requires recalculating foreign tax to reflect only the taxed portion (you cannot credit tax on excluded earnings)
FTC limitation is computed by category (passive, general, GILTI, foreign branch), preventing cross-category cross-subsidy

When stacking is the right move:

You earn well above the FEIE cap (tech, finance, medicine in high-pay cities)
You have significant unearned income alongside earned income
Your foreign country has high tax rates that generate excess credits

Stacking is more complex than using FTC alone. In a high-tax country, Form 1116 alone often yields a simpler, equally strong result.
