U.S. Expat Taxes: 14 Tips From Our Tax Experts

Moving abroad doesn’t automatically end your U.S. tax obligations. U.S. citizens and resident aliens still have to report worldwide income when they meet the filing requirements, even if they earn everything overseas and pay tax there.

At Bright!Tax, we help Americans abroad work through these rules every day. These 14 tips from our expat tax team cover the decisions, deadlines, and reporting details that can make the biggest difference to your return.

Tip 1: Know that living abroad does not erase your U.S. filing requirements

Your address can change without changing your obligation to file a U.S. return.

U.S. citizens and green card holders who remain U.S. tax residents are subject to tax on worldwide income. That can include foreign wages, freelance earnings, rent, pensions, investment income, and income already taxed by another country.

Whether you must file depends on your income, age, filing status, and other filing triggers.

Situation	What to check
You earn a salary overseas	Compare worldwide gross income with the applicable filing threshold.
You expect to exclude your salary using the FEIE	Include that income when determining whether you must file.
You work for yourself	Net self-employment earnings of $400 or more can trigger a return even below the ordinary income threshold.
You are married filing separately	This status has a particularly low gross-income filing threshold.
You have foreign accounts but little income	FBAR reporting can apply independently of an income-tax return.

Consider Sofia, a U.S. citizen employed in Spain who earns $70,000. Even if she qualifies to exclude all her salary, she cannot simply compare zero income with the filing threshold. The IRS requires her to count the foreign earnings before that exclusion.

For our Bright!Tax clients, we separate two questions from the start: “Do I need to file?” and “Will I owe tax?” The answers can be yes and no.

Tip 2: Understand your U.S. residency position before you file

For tax purposes, residency isn’t just a question of where you spend most nights.

Your status affects which income you report, which return you file, and whether treaty provisions or special elections apply.

Status	Starting point for federal income tax
U.S. citizen	Worldwide taxation continues while living abroad.
Green card holder	Normally a U.S. tax resident until residency ends under the applicable rules.
Other resident alien	Residency can arise under the Substantial Presence Test or an applicable election.
Nonresident alien	Generally subject to different rules focused on specified U.S. income.
Dual-status taxpayer	Resident for part of the year and nonresident for another part.

The Green Card Test and Substantial Presence Test are the main starting points for noncitizens. Exceptions, treaty positions, residency elections, and starting or ending dates can change the result.

For example, Arjun moves from the U.S. to India in July but keeps his green card. Spending the rest of the year overseas doesn’t, by itself, make him a nonresident for U.S. tax purposes.

We would review his immigration history, tax residency, and any treaty position before choosing the return—not assume that his flight date settled everything.

Tip 3: Report foreign income even when it never touched a U.S. bank account

Foreign income doesn’t stop being reportable because it was paid in euros, taxed in Australia, or left in a Singapore bank account.

For U.S. citizens and resident aliens, reportable worldwide income can include:

• Foreign salary and bonuses.
• Self-employment and business income.
• Rental income.
• Pension distributions.
• Interest, dividends, and investment gains.
• Income already taxed overseas.

The income belongs on the appropriate lines, schedules, and supporting forms of your U.S. return.

Foreign currency adds another step. You must translate reportable amounts into U.S. dollars, using the appropriate exchange-rate method.

Suppose Claire works in France and keeps her entire salary in a French account. She never transfers it to the U.S. That doesn’t change whether the salary is reportable. The account itself may also create a separate foreign-account reporting obligation.

Tip 4: Use the Foreign Earned Income Exclusion carefully

The Foreign Earned Income Exclusion, or FEIE, lets eligible taxpayers exclude qualifying foreign earned income from federal income tax.

For tax year 2026, the maximum is $132,900 per qualifying person. Partial-year qualification can reduce that limit.

To qualify, you need foreign earned income, a foreign tax home, and either:

• Eligibility under the bona fide residence rules.
• At least 330 full days in foreign countries during a qualifying 12-month period under the physical presence rules.

The eligibility rules differ in some respects for U.S. citizens and resident aliens. You claim the exclusion using Form 2555.

Income or tax	Does the FEIE cover it?
Qualifying salary for work performed abroad	Yes, within the applicable limit
Qualifying foreign self-employment earnings	Yes, for income-tax purposes
Interest, dividends, and capital gains	No
Pension and Social Security income	No
Ordinary passive rental income	No
U.S. self-employment tax	No

Qualifying housing costs can also support a foreign housing exclusion or deduction, subject to separate rules.

Another detail we check at Bright!Tax is stacking. Excluding salary doesn’t mean your remaining taxable income automatically starts in the lowest bracket. The calculation generally uses the rates that would apply if the excluded income were still included.

Tip 5: Compare the Foreign Tax Credit before choosing your strategy

The Foreign Tax Credit, or FTC, can reduce U.S. income tax using qualifying foreign income taxes.

It works differently from the FEIE: income stays in the U.S. calculation, while the credit offsets qualifying U.S. tax.

Question	Foreign Earned Income Exclusion	Foreign Tax Credit
What does it do?	Excludes qualifying foreign earned income	Credits qualifying foreign income taxes
What income can it help with?	Eligible earnings from work abroad	Qualifying income within the applicable sourcing and credit rules
Is there a fixed annual dollar cap?	Yes: $132,900 for 2026 before proration	No equivalent flat cap; credit limitations apply
Which form is normally used?	Form 2555	Form 1116, with exceptions
Can unused amounts carry over?	Unused annual exclusion doesn’t carry over	Certain unused credits can carry back one year and forward ten years
Does it eliminate self-employment tax?	No	No

Imagine Marcus lives in Germany and pays substantial German income tax on his salary. Choosing the FEIE solely because his earnings fit under the cap could overlook a better FTC result.

At Bright!Tax, we compare the FEIE and Foreign Tax Credit using the full return, including income categories, foreign taxes, family circumstances, and existing elections.

You can use both on one return, but you cannot claim an FTC for foreign taxes attributable to FEIE-excluded income.

The Form 1116 rules also include exceptions allowing some taxpayers to claim the credit without that form. Paying tax overseas isn’t enough by itself: creditability, sourcing, timing, and category limits still matter.

Tip 6: Mark your expat tax deadlines early

Qualifying taxpayers abroad receive extra filing time, but filing dates, payment rules, and interest don’t all follow the same timetable.

For a normal calendar-year return, these are the main dates:

Date	What it means
April 15	Regular federal filing and payment deadline; interest normally starts on unpaid tax after this date
June 15	Automatic filing and payment extension for qualifying taxpayers abroad, although interest runs from the regular April deadline
October 15	Extended filing deadline when a valid extension has been requested
April 15, automatically extended to October 15	Normal FBAR filing timetable

Weekends, holidays, and specific relief can change deadlines.

To use the automatic overseas extension, you must meet the eligibility conditions and attach the required statement.

If you qualify for June 15 but need longer, file Form 4868 by that deadline to request filing time through October 15. That later extension doesn’t normally extend payment time.

Form 2350 serves a different purpose: it can give eligible taxpayers time to meet the foreign residence or physical presence requirements for certain exclusions.

One distinction matters: the return normally filed during 2026 reports 2025 income; tax-year 2026 income is normally reported in 2027.

Tip 7: Check whether you still owe state taxes

Leaving the U.S. doesn’t automatically end your state tax obligations.

Your former state can examine domicile, time spent there, retained connections, and state-source income.

Factor	Why it can matter
A home or other property	Can affect domicile, residency, or income sourcing
Spouse or dependents in the state	Can support an ongoing connection
Driver’s license and vehicle registration	Can provide evidence of retained ties
Business interests or work performed there	Can create state-source income
Days spent in the state	Can affect statutory residency
Evidence of establishing a home abroad	Can support a change in domicile

California taxes worldwide income during residency and California-source income during nonresidency. New York considers domicile, permanent places of abode, and day counts. Virginia domicile can continue despite foreign employment unless it is properly abandoned.

For example, Elena moves to Italy but keeps a rental property in California. Even after establishing nonresidency, California-source rental income can still require a state return.

Florida, Texas, Nevada, Washington, South Dakota, Tennessee, Wyoming, Alaska, and New Hampshire have no broad individual income tax. That doesn’t remove every state tax: Washington, for example, taxes certain capital gains.

Tip 8: Track foreign bank accounts before they become an FBAR issue

The FBAR reports foreign financial accounts separately from your income-tax return. It doesn’t calculate income tax, and you can need it even when you owe no U.S. income tax.

Under the FinCEN reporting rules, a U.S. person generally must file when reportable foreign accounts exceed $10,000 in aggregate, subject to applicable exceptions.

Accounts can include foreign:

• Bank accounts.
• Brokerage accounts.
• Certain pension and investment accounts.
• Accounts over which you have signature authority, even without owning the money.

The threshold isn’t a $10,000 allowance for each account.

Suppose Nia lives in Kenya and has three reportable accounts:

Account	Maximum annual value in U.S. dollars
Current account	$4,000
Savings account	$3,500
Brokerage account	$3,000
Total maximum values	$10,500

Applying the prescribed maximum-account-value calculation, those accounts exceed the threshold even though none individually reaches $10,000.

For our Bright!Tax clients, we include account reporting in the initial review rather than waiting until the income-tax calculation is finished.

Tip 9: Know when Form 8938 applies

Form 8938 also reports foreign assets, but it isn’t interchangeable with the FBAR.

Question	FBAR	Form 8938
Where is it filed?	Separately with FinCEN	With your U.S. income-tax return
What does it cover?	Reportable foreign financial accounts	Specified foreign financial assets, including some assets held outside accounts
Main threshold	More than $10,000 in aggregate	Depends on filing status and eligibility for overseas thresholds
Does signature authority alone normally count?	It can	Generally no
Required without an income-tax return?	It can be	Normally no
Does one replace the other?	No	No

Specified foreign financial assets can include accounts, certain pensions, foreign shares held outside an account, and interests in foreign entities.

Higher thresholds apply only if you satisfy the Form 8938 overseas eligibility rules, including a foreign tax home and the required presence-abroad conditions.

Eligible taxpayer living abroad	Year-end value exceeds	Value at any time exceeds
Unmarried or married filing separately	$200,000	$300,000
Married filing jointly	$400,000	$600,000

For example, Hannah qualifies for the overseas thresholds and files separately. Specified foreign assets worth $220,000 at year-end exceed her Form 8938 threshold. Reportable foreign accounts within those assets may also require an FBAR.

Tip 10: Do not overlook foreign pensions, investments, and business structures

An arrangement that is routine locally can create unfamiliar U.S. forms.

This is particularly relevant to foreign pensions, pooled investments, and business ownership.

Arrangement	U.S. reporting to review
Foreign mutual funds and pooled investments	PFIC classification and Form 8621
Foreign corporations	Form 5471 and other applicable shareholder reporting
Foreign partnerships	Form 8865
Foreign disregarded entities or branches	Form 8858
Foreign trusts and some pension arrangements	Forms 3520/3520-A, subject to exemptions
Foreign accounts and pension interests	FBAR and Form 8938, where applicable

A pension’s local tax benefits don’t automatically carry over to the U.S. That applies when reviewing arrangements such as SIPPs, schemes with QROPS status, Australian superannuation, and provident funds.

We look at the actual structure, contributions, distributions, ownership, and treaty rules. A product name alone doesn’t establish its U.S. treatment.

Take Omar, who lives in the Netherlands and is considering a locally marketed investment fund. Before he invests, we would check whether it is a PFIC and what that means for annual reporting and taxation.

Tip 11: Understand self-employment tax before you invoice from abroad

The FEIE can reduce federal income tax on qualifying business earnings. It doesn’t reduce the earnings used to calculate U.S. self-employment tax.

That distinction matters for freelancers, consultants, independent contractors, and other business owners.

Sole proprietors and qualifying disregarded-entity owners normally report business income and expenses on Schedule C. Other structures, including partnerships, use different reporting routes.

Issue	What we check
Business profit	Income after allowable business expenses
Self-employment tax	Schedule SE rules, including the $400 net-earnings threshold
FEIE	Whether qualifying earnings can be excluded from income tax
Foreign social insurance	Whether a totalization agreement assigns coverage to the other country
Payments during the year	Whether estimated payments or additional withholding are needed

Suppose Ben runs a consulting business in Dubai with $60,000 of receipts and $15,000 of allowable expenses. His $45,000 profit could qualify for the FEIE if he meets the requirements.

That doesn’t, by itself, remove his self-employment tax. We would calculate that separately.

Totalization agreements can prevent dual social-security coverage in participating countries. Where an agreement assigns coverage abroad, appropriate documentation is important to support the U.S. exemption.

Tip 12: Get expert help before the return becomes a cleanup project

A salary-only return can become more involved when you add a foreign pension, state residency, a business, or several years of missed reporting.

At Bright!Tax, we assess those pieces together. A useful review starts with more than your latest payslip.

Information to gather	What it helps establish
Prior U.S. returns and IRS notices	Filing history, elections, carryovers, and unresolved issues
Income records from each country	Worldwide income and sourcing
Account and investment statements	FBAR, Form 8938, and investment reporting
Pension documents	Contributions, distributions, transfers, and classification
Travel and residency records	Exclusion eligibility and residency
Business records	Entity classification, expenses, and information returns
Foreign tax records	Potential credits and timing differences

The scope and cost of preparation depend on the work required. A return involving a foreign company, pension transfer, and missing years needs a different review from a straightforward employment return.

Tip 13: If you are behind, make a catch-up plan while staying current

Discovering missed U.S. obligations doesn’t mean you should start sending forms at random. It also doesn’t mean you should let the current year become another missed deadline.

Start by identifying what is missing: income-tax returns, FBARs, foreign-asset forms, business reporting, and any state filings.

Situation	Possible route to assess
Non-willful offshore reporting failures	Streamlined Filing Compliance Procedures, if all eligibility conditions are met
Missing FBARs with related income properly reported and tax paid	Delinquent FBAR Submission Procedures, if eligible
Other late returns or information forms	Applicable late-filing procedures, reasonable-cause relief, or another appropriate approach
Potentially willful conduct	Specialist legal advice about the appropriate disclosure route

Consider Amara, who lives in Canada and discovers several years of missed U.S. filings shortly before her current return is due. We would assess the historical omissions while deciding how to keep the current filing and payment obligations on track.

Submitting late returns outside a formal program isn’t automatically wrong. But it doesn’t automatically provide the penalty treatment available through an applicable compliance procedure.

Catching up can also uncover refunds. Those claims have time limits, so delaying can cost money even when no tax is owed.

Tip 14: Understand exit tax before renouncing citizenship or giving up a green card

Renouncing citizenship or ending long-term permanent residency can create tax obligations separate from your final ordinary return.

The U.S. exit tax can apply to covered expatriates. It isn’t a standard departure fee: certain assets are treated as sold on the day before expatriation, while other assets follow special rules.

For expatriations in 2026, covered status can arise under these tests:

Test	Threshold or requirement
Net worth	$2 million or more on the expatriation date
Average annual net income tax liability	More than $211,000 over the preceding five tax years
Tax compliance certification	Failure to certify compliance with U.S. federal tax obligations for the preceding five tax years

Certain dual citizens and minors can qualify for exceptions from the wealth and liability tests, but the compliance certification still matters.

A long-term resident generally held lawful permanent resident status in at least eight of the preceding 15 tax years, subject to treaty-related rules.

For example, David has a net worth of $1.5 million and expects no exit-tax issue when renouncing. That figure alone doesn’t settle his position. We would still check his five-year tax liability, compliance certification, and other applicable requirements.

Form 8854 is central to expatriation reporting. Covered status also doesn’t automatically mean a tax payment is due: asset types, basis, exclusions, and special rules affect the calculation.
