Tax Q&A in category: Business & Self-Employment Abroad

Question 1

How do I know if my employer is considered a foreign affiliate for U.S. tax purposes?

Accepted Answer

Your employer is a foreign affiliate when it is a foreign entity in which a U.S. person (usually a parent corporation) owns more than 50% of the voting stock or value, directly or indirectly. The IRS definition sits in IRC Section 3121(l), and it matters for Social Security coverage, Form 5471 reporting, and W-2 eligibility.

Three practical tests signal foreign-affiliate status:

A U.S. parent company owns more than 50% of the foreign entity
The U.S. parent has entered a Section 3121(l) agreement, so U.S. Social Security and Medicare apply to American employees abroad
You are paid through a foreign subsidiary but receive a U.S. W-2 covering FICA

Why it matters for your expat return:

If you are unsure, ask HR for a copy of your employment entity’s ownership chain and for confirmation of whether a Section 3121(l) agreement is in force.

Question 2

Can I file Form 8858 instead of Form 5471 as the sole owner of my foreign LLC?

Accepted Answer

Yes, if your foreign LLC is classified as a foreign disregarded entity (FDE) under U.S. tax rules, you file Form 8858 instead of Form 5471. The deciding factor is entity classification, not the name of the form used by the foreign country.

How to tell which form applies: Entity typeU.S. tax classificationForm filedForeign LLC, single owner, defaultForeign disregarded entityForm 8858Foreign LLC, elected C-corp (Form 8832)Foreign corporationForm 5471Foreign LLC, multi-member, defaultForeign partnershipForm 8865Foreign LLC on “per se” list (e.g. UK Ltd, German GmbH)Corporation alwaysForm 5471

Entities on the Treasury “per se” corporate list cannot elect to be disregarded. This list includes UK Limited, German GmbH (AG is always a corporate form), French SA, Spanish SA, and Canadian corporations (but not Canadian ULCs, which default to disregarded). A UK LLP can elect to be disregarded for a single member.

Form 8858 is generally simpler than Form 5471:

Shorter schedule structure (3 to 4 pages vs 20+)
No Subpart F or GILTI inclusion (since the entity is transparent)
Income and expenses flow directly to your Schedule C or Schedule E

Late filing on either form triggers a $10,000 penalty per form per year (IRC 6038). Penalties stack quickly for multi-year delinquency.

For form selection and deeper reporting rules, see our foreign business reporting guide.

Question 3

Can I take the home office deduction if I work remotely from a foreign rental apartment?

Accepted Answer

Yes. If you are self-employed and living in a foreign rental, you can claim the home office deduction on your U.S. tax return as long as the space is used regularly and exclusively for business and is your principal place of business. The deduction is available under both the simplified and actual-expense methods.

The two calculation methods: MethodHow it worksMax deductionSimplified$5 per sq ft of qualified space300 sq ft = $1,500Actual expenseBusiness-use % of rent, utilities, internet, insurance, maintenanceNo cap (Form 8829)

The actual-expense method almost always produces a larger deduction for expats in higher-rent cities like London, Paris, Singapore, or Dubai. To calculate the business-use percentage, divide the square footage of the exclusive work area by the total apartment square footage.

Important rules for expats:

The space must be used exclusively for business. A kitchen table used for work and dinner does not qualify.
Regular use means on a continuing basis, not occasional
Employees (W-2 workers) cannot claim the home office deduction through 2025 under the TCJA suspension
The deduction is not available if you use the Foreign Earned Income Exclusion on the same income (the FEIE already excluded the gross earnings)
Convert rent and utility amounts to U.S. dollars using a consistent exchange rate method

You claim it on Schedule C (sole proprietors), with Form 8829 attached, using the actual-expense method.

For guidance on stacking deductions with the FEIE or FTC, see our self-employed expat deductions guide.

Question 4

Can I use the Foreign Earned Income Exclusion on self-employment income as a U.S. expat?

Accepted Answer

Yes, the Foreign Earned Income Exclusion (FEIE) can exclude up to $130,000 of self-employment income from U.S. income tax in 2025 ($132,900 in 2026), but it does not reduce 15.3% self-employment tax. You claim the exclusion by filing Form 2555 with Form 1040.

Self-employment earnings qualify as foreign earned income when:

The services are performed in a foreign country
You have a tax home abroad
You pass either the Physical Presence Test (330 full days abroad in 12 months) or the Bona Fide Residence Test

What the FEIE covers and does not cover: Tax typeFEIE effectU.S. income tax on excluded earningsEliminated up to $130,000Self-employment tax (Social Security + Medicare)Not reduced, full 15.3% still owedIncome above the exclusionTaxed at graduated ratesPassive income (interest, dividends)Not excluded

Because the SE tax still applies, self-employed expats often have an effective tax burden of 15.3% on covered earnings even when the FEIE zeroes out income tax. A totalization agreement is the only way to eliminate SE tax entirely. 30+ countries have one, including the U.S., the UK, Germany, France, Canada, Australia, Japan, and South Korea.

Strategy tip: if you live in a high-tax country and paid significant foreign tax, the Foreign Tax Credit may produce a better result than the FEIE because it can also offset tax on unearned income and does not lock you out of future choices for five years.

For side-by-side FEIE vs FTC analysis for self-employed filers, see our foreign earned income exclusion guide.

Question 5

Do I have to report foreign business income if my business operates at a loss?

Accepted Answer

Yes. All foreign business income must be reported on your U.S. tax return, even when the business operates at a loss. A properly reported loss can reduce your overall tax bill by offsetting other income in the same year or carrying forward to future years.

You report foreign business activity based on entity type:

Sole proprietor / disregarded entity: Schedule C, with Form 8858 if the entity is foreign
Partnership: Schedule E and Form 8865 for foreign partnerships
S-Corp: Schedule E and K-1
Foreign corporation: Form 5471, with Subpart F or GILTI applying separately

Why should you still file with a loss:

A net operating loss (NOL) can offset W-2 wages, investment income, or spousal income in the same year (Schedule C losses specifically)
Unused losses can carry forward indefinitely to offset future business income (80% limitation post-TCJA)
Failure to file triggers $10,000+ penalties on international information returns (5471, 8865, 8858) even when there is no tax due
Missing years block you from amending or claiming carryforwards later

Key reporting reminders:

Convert foreign currency losses to U.S. dollars using the same method you use for income
Track basis in the foreign entity; losses can only be deducted to the extent of your basis
Passive losses from rental or investment activity have separate limitation rules under Section 469

For more on reporting foreign businesses correctly, see our foreign business tax guide.

Question 6

Do I need to file Form 5471 if I own less than 10% of a foreign corporation?

Accepted Answer

In most cases, no. Form 5471 filing is triggered at 10% or greater direct, indirect, or constructive ownership of a foreign corporation. If you own under 10%, you generally do not file. But there are exceptions where even a small stake can pull you into a filing category.

The five filer categories at a glance: CategoryWho filesOwnership thresholdCategory 1U.S. shareholder of a specified foreign corporation10%+Category 2U.S. officer/director when a U.S. person acquires 10%+10%+ acquisition by anotherCategory 3U.S. person acquiring 10%+ or disposing to drop belowTriggered by transactionCategory 4U.S. person with control (>50%) of a foreign corporation50%+Category 5U.S. shareholder of a controlled foreign corporation (CFC)10%+ vote or value Situations where under 10% can still trigger Form 5471:

Constructive ownership through family attribution (spouse, children, parents, grandparents, grandchildren) can aggregate holdings above 10%
Category 2 officer/director duty: you may file if a U.S. person crosses the 10% line and you are an officer or director
An acquisition in a transaction where your combined pre- and post-transaction ownership crosses a threshold

The penalty for missing a required 5471 is $10,000 per form per year, climbing by $10,000 increments after IRS notice, capped at $60,000. A passive investor with a tiny foreign equity stake usually has no filing obligation, but anyone with family connections to other U.S. investors in the same corporation should carefully run through the attribution rules.

For guidance on Form 5471 filer categories, see our Form 5471 guide.

Question 7

Do I need to file Form 8865 if I have a small foreign partnership interest?

Accepted Answer

It depends on your filer category. Form 8865 has four categories, and a U.S. person with at least a 10% direct or constructive interest in a foreign partnership usually has a filing obligation, but smaller stakes can also trigger filing during acquisitions, transfers, or contributions.

The four Form 8865 filer categories: CategoryWho filesThresholdCategory 1U.S. person controlling a foreign partnership>50% interestCategory 2U.S. person owning 10%+ when partnership controlled by U.S. persons10%Category 3U.S. person contributing property and meeting thresholds$100,000+ contribution or 10%+ post-contributionCategory 4U.S. person with reportable acquisition or dispositionCrossing 10% Situations where even a small interest can pull you in:

Contributing property worth $100,000 or more during the year to any foreign partnership
Cumulative contributions over 12 months totaling $100,000+
A change in interest where your ownership moves from below 10% to at or above 10%, or vice versa
Constructive ownership through family attribution pushes your effective interest above 10%

Penalties for missing Form 8865 mirror Form 5471: $10,000 per form per year, increasing after IRS notice, plus a 10% reduction in allowable foreign tax credits attributable to the partnership.

If your interest is clearly under 10% with no contribution or disposition activity, you generally have no Form 8865 filing obligation. But double-check the attribution rules if family members hold stakes in the same partnership.

For detailed filer-category analysis, see our Form 8865 guide.

Question 8

Do I have to report my foreign partnership to the IRS?

Accepted Answer

Yes. If you are a U.S. person with an ownership interest in a foreign partnership, you generally file Form 8865 along with your Form 1040. Whether you file as a Category 1, 2, 3, or 4 filer depends on your ownership percentage, control of the partnership, and whether you contributed property or triggered an acquisition event.

You report your distributive share of partnership income, deductions, and credits on Schedule E and carry those numbers to Form 1040. A foreign partnership is any entity classified as a partnership under U.S. tax rules (multi-member LLC or foreign equivalent) that is organized outside the United States.

Common filing triggers:

Controlling interest (>50%) in a foreign partnership = Category 1 filer
10% or greater interest when U.S. persons collectively control the partnership = Category 2
Property contributions of $100,000+ during the year = Category 3
Reportable acquisition or disposition crossing the 10% threshold = Category 4

Related filings that often accompany Form 8865:

Form 8938 (FATCA) if total foreign financial assets exceed the threshold
FinCEN Form 114 (FBAR) if the partnership has foreign bank accounts where you have signature authority
Form 1116 if foreign tax is paid at the partnership level

Penalties for failing to file Form 8865 start at $10,000 per partnership per year and increase to $60,000 after IRS notice.

For complete filing guidance, see our Form 8865 reporting guide.

Question 9

How are U.S. taxes calculated for a foreign sole proprietorship owned by an American?

Accepted Answer

A foreign sole proprietorship is a disregarded entity for U.S. tax purposes, meaning you report all business income and expenses directly on Schedule C of your personal Form 1040. You owe U.S. income tax on the net profit and 15.3% self-employment tax unless a totalization agreement exempts you.

The calculation flow:

Gross receipts from all clients and sales (in U.S. dollars)
Minus ordinary and necessary business expenses
Equals net profit on Schedule C
Net profit times 92.35% equals net earnings from self-employment
Net earnings times 15.3% equals self-employment tax
Net profit flows to Form 1040, reduced by half the SE tax (adjustment to income)
Apply FEIE or FTC to reduce U.S. income tax (but not SE tax)

What counts as business income:

Service fees, consulting revenue, freelance payments
Product sales net of cost of goods sold
Royalties from self-created intellectual property

Required filings for foreign sole proprietors:

Schedule C (net profit and expense detail)
Schedule SE (self-employment tax)
Form 2555 if claiming FEIE, or Form 1116 if claiming FTC
Form 8938 if foreign financial assets cross the threshold
FBAR (FinCEN 114) if foreign business accounts exceed $10,000 aggregate
Form 1040-ES quarterly estimated payments if the total tax owed will exceed $1,000

Currency conversion uses the IRS’s yearly average rate or a consistent monthly average. Document your method and apply it consistently year over year.

For more on structuring and filing as a sole proprietor abroad, see our self-employed expat tax guide.

Question 10

Do U.S. self-employed expats have to pay self-employment tax if the country has no totalization agreement?

Accepted Answer

Yes. Without a totalization agreement between the U.S. and your country of residence, you owe the full 15.3% U.S. self-employment tax on net earnings of $400 or more, even if you are also paying into the foreign social security system. This creates a double social-security burden that can approach 30% combined.

The 15.3% U.S. SE tax breaks down as:

12.4% Social Security (on earnings up to the annual Social Security wage base)
2.9% Medicare (uncapped)
Additional 0.9% Medicare surtax on earnings above $200,000 (single) or $250,000 (MFJ)

You can deduct half the SE tax as an adjustment to income, which partially softens the hit.

Countries with totalization agreements (current list; verify at SSA.gov): Australia, Austria, Belgium, Brazil, Canada, Chile, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, United Kingdom, and Uruguay.

Countries without a U.S. totalization agreement where expats frequently live include the UAE, Singapore, Hong Kong, Thailand, Mexico, Colombia, Costa Rica, Panama, Vietnam, Indonesia, Malaysia, Taiwan, New Zealand, and most of Africa.

Workarounds when no agreement exists:

Structure your activity through a foreign corporation that employs you (paying a reasonable salary may or may not trigger U.S. tax depending on CFC/GILTI rules)
Incorporate a U.S. C-corp and pay yourself W-2 wages (FICA applies, but employer and employee portions are split formally)
Accept the double-tax cost if structure changes are not practical

For strategy on reducing SE tax abroad, see our Totalization Agreements Guide.

Question 11

If my country has no U.S. totalization agreement, do I owe Social Security taxes in both countries?

Accepted Answer

Yes. If your country of residence does not have a totalization agreement with the United States, you will likely owe Social Security tax to both countries on the same income. The U.S. does not give a credit or deduction for foreign social security contributions.

The double-tax scenario typically applies to self-employed Americans in countries like the UAE, Singapore, Thailand, Mexico, Hong Kong, Taiwan, New Zealand, Indonesia, and most of Africa. W-2 employees of truly foreign employers usually avoid the U.S. side because they are not subject to U.S. FICA, but self-employed workers owe the full 15.3% U.S. SE tax.

The practical cost stack:

U.S. SE tax: 15.3% on net earnings up to the wage base, 2.9% above
Foreign social security: variable, often 8% to 25% of earnings
Combined: can exceed 25% of gross self-employment income before income tax

Ways to reduce the pain:

Deduct half the U.S. SE tax as an adjustment to income on Form 1040
Claim foreign social security as a foreign tax for Foreign Tax Credit purposes only if it qualifies as a compulsory income tax (most foreign SS payments do not qualify)
Restructure through a foreign corporation that pays wages instead of distributions
Consider whether partial-year status in a totalization-agreement country makes sense for high-earning years

Vested foreign contributions may still earn you a foreign retirement benefit, and the Social Security Fairness Act (enacted in 2025) repealed the WEP and GPO offsets, so foreign pensions no longer reduce your U.S. Social Security benefit at retirement.

For more strategy, see our Totalization Agreements Guide.

Question 12

If I own a foreign corporation, am I automatically subject to GILTI or NCTI?

Accepted Answer

No. For your 2025 return, GILTI (Global Intangible Low-Taxed Income) applies only if you are a U.S. shareholder of a controlled foreign corporation (CFC), meaning you own at least 10% of the vote or value of a foreign corporation that is more than 50% owned by U.S. shareholders. If your ownership falls below 10% or the entity is not a CFC, neither GILTI nor its 2026 replacement applies.

Two tests must both be met: TestThresholdWho satisfiesU.S. shareholder10%+ vote or valueYou personallyControlled foreign corporationU.S. persons own >50%Aggregate U.S. shareholders What changed in 2026: GILTI becomes NCTI

The One Big Beautiful Bill Act (signed July 4, 2025) replaced GILTI with Net CFC Tested Income (NCTI), effective for tax years beginning after December 31, 2025. The ownership thresholds above remain unchanged, but the calculation is significantly different:

GILTI (your 2025 return)NCTI (2026+ returns)QBAI deduction10% return on tangible assets excludedEliminated — all tested income includedSection 250 deduction (corps / Section 962)50%40%Effective rate (corp or Section 962 election)~10.5%~12.6%Foreign Tax Credit — creditable portion80%90%Break-even foreign tax rate~13.1%~14%High-tax exclusion threshold18.9% (90% of 21%)~14%Reporting formForm 8992Form 8992 (updated)

The NCTI base is broader: removing the QBAI deduction means CFC profits backed by substantial tangible assets abroad are fully included, not partially sheltered.

2025 GILTI mechanics (your current filing year)

When GILTI applies, your pro-rata share of the CFC’s tested income above a 10% return on tangible assets flows to your personal return via Form 8992 and Schedule 1.

Problems GILTI creates for individual owners:

GILTI is taxed at ordinary income rates for individuals (no 50% deduction without a Section 962 election)
No Foreign Tax Credit is automatically available at the individual level without a Section 962 election
Cash trapped in the CFC is still taxed currently, creating a dry-tax liability

Strategies that apply to both years

Section 962 election: to be taxed as if a domestic C-corp (accesses Section 250 deduction and FTC, but creates layered tax on later dividends). Deduction is 50% for 2025, 40% for 2026+.
High-tax exclusion: if the CFC’s effective foreign rate exceeds 18.9% for your 2025 return, or approximately 14% for 2026+, income can be excluded
Restructuring to a disregarded entity (Form 8858) where practical

For a detailed breakdown of how GILTI and NCTI compare, see our GILTI and NCTI guide.

Question 13

How are U.S. self-employment taxes calculated when I work as a freelancer or creative professional abroad?

Accepted Answer

U.S. citizens and green card holders working as freelancers or creative professionals abroad owe self-employment (SE) tax at 15.3% on net earnings of $400 or more, even when all income is earned outside the United States. The tax covers Social Security (12.4% up to the annual Social Security wage base) and Medicare (2.9%, uncapped).

SE tax applies to your net earnings from self-employment, calculated as gross income minus deductible business expenses, multiplied by 92.35%. You then apply the 15.3% rate. You can also deduct half the SE tax on your Form 1040 as an adjustment to income.

The Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit (FTC) do not reduce SE tax. Both only shield you from U.S. income tax. This is one of the most painful surprises for freelancers abroad who assumed the FEIE covered everything.

You can avoid SE tax only when:

Your country has a totalization agreement with the U.S., and you obtain a certificate of coverage from the foreign social security authority
You operate through a foreign corporation that classifies you as an employee (with its own tax trade-offs)
Your net self-employment earnings are under $400 for the year

File SE tax on Schedule SE, attached to Form 1040. Quarterly estimated payments (Form 1040-ES) are often required since no employer is withholding.

For strategies to reduce SE tax through totalization agreements or entity structure, see our self-employment tax guide for expats.

Question 14

What is the best business structure for a U.S. expat running a consulting business abroad?

Accepted Answer

There is no single best business structure. The right choice depends on your income level, your country of residence (whether a totalization agreement applies), and how much of your time you spend serving U.S. versus foreign clients. Most expat consultants use one of three structures.

Quick comparison: StructureBest forSE taxSetup burdenSole proprietor / disregarded SMLLCIncome under ~$150k, single-country residency15.3% unless totalization appliesLowForeign corporationLong-term residents of no-totalization countries, income $150k+Avoidable via W-2 wagesHigh (Form 5471, GILTI)S-corp (rare for expats)U.S.-facing consultants willing to maintain U.S. residency linkReduced via reasonable salary splitModerate Key factors that should drive the decision:

Totalization agreement availability: if your country has one, a sole prop with a certificate of coverage solves most problems
Expected income: under $100k net, structured savings rarely justify the complexity
Client mix: U.S. clients paying in USD favor a U.S. entity; foreign clients paying in local currency favor a foreign structure
Long-term residency: planning to stay 5+ years in a country without a totalization agreement strengthens the case for a foreign corp
GILTI exposure: a foreign corp triggers GILTI, which can be painful without a Section 962 election

S corporations are mostly unavailable to expats because S-corp shareholders must be U.S. residents or citizens, and a nonresident alien spouse can disqualify the election.

For personalized structure analysis, see our expat tax guide for starting a business overseas.

Question 15

What tax forms do self-employed U.S. expats need to file each year?

Accepted Answer

Self-employed U.S. expats typically file Form 1040, Schedule C, Schedule SE, Form 2555 or Form 1116, and potentially FinCEN Form 114 (FBAR) and Form 8938, depending on foreign asset balances. The exact list depends on business structure, income, and whether foreign accounts or entities are involved.

Core filings for every self-employed expat:

Form 1040: annual income tax return
Schedule C: profit or loss from business (sole proprietors and single-member LLCs)
Schedule SE: self-employment tax calculation
Form 2555 (FEIE) or Form 1116 (FTC) or both
Form 1040-ES: quarterly estimated tax payments if total tax exceeds $1,000

Foreign account and asset reporting:

FinCEN Form 114 (FBAR): if foreign financial accounts exceed $10,000 aggregate at any point in the year
Form 8938 (FATCA): if foreign financial assets exceed thresholds ($200k/$400k for singles/MFJ living abroad at year-end; higher for MFJ)
Form 8621: if you hold a Passive Foreign Investment Company (PFIC)

Business structure add-ons: StructureAdditional formsMulti-member foreign LLC (partnership)Form 8865Foreign disregarded entity / foreign branchForm 8858Foreign corporation (10%+ owner)Form 5471, Form 8992 (GILTI)U.S. LLC owned by foreign-residentForm 5472 if single-memberForeign gifts receivedForm 3520 if over $100,000 from foreign individual

Miss a form and penalties start at $10,000 per form for international information returns, even when no tax is owed.

For a walkthrough of each filing, see our self-employed expat filing guide.

Question 16

What does "creative" mean for U.S. taxes, and why does it matter?

Accepted Answer

“Creative” for U.S. tax purposes describes work that produces original intellectual property such as writing, design, music, film, photography, coding, and visual art. The classification matters because creative income is often personal services income (sourced to the location where the work is performed), but royalty streams are sourced to the location where the intellectual property is used.

How the distinction plays out on your return:

Upfront fees for creative services (a commissioned book, a photo shoot, a video production) are personal services income and are sourced to your physical location while the work is being performed. If you performed the work abroad, it qualifies as foreign earned income for FEIE.
Royalties (ongoing payments for use of your book, song, or software license) are sourced to where the IP is used, not where you created it. A song licensed in the U.S. generates U.S.-source royalty income even if you live in Portugal.
Mixed contracts (a design fee plus future royalties) require allocation between the personal services piece and the royalty piece, each sourced differently.

Why sourcing matters:

FEIE only applies to earned income, which generally means personal services, not royalties
FTC category: personal services is typically a general category; royalties are passive
Self-employment tax applies to active creative services but not to passive royalty streams
Section 199A (qualified business income) deduction is available for creative businesses meeting SSTB rules, subject to income phaseouts

For sourcing rules and strategic planning for creative expats, see our dedicated services for self-employed expats.

Question 17

When do I need to register my foreign business with the IRS?

Accepted Answer

You register a foreign business with the IRS when it needs an Employer Identification Number (EIN), reports U.S.-source income, or triggers informational filings like Form 5471, Form 8865, or Form 8858. Foreign businesses do not file their own Form 1040, but many situations require contact with the IRS.

Common triggers to register (get an EIN or file informational returns):

You want an EIN to open a U.S. bank account or issue U.S. 1099s
The business has U.S.-source income (income from U.S. clients paid to the foreign entity)
You are a U.S. person with 10%+ ownership in a foreign corporation (Form 5471)
You contribute property valued at $100,000 or more to a foreign partnership (Form 8865)
Your foreign business operates as a disregarded entity owned by a U.S. person (Form 8858)
The foreign business is a foreign-owned U.S. single-member LLC (Form 5472)

How to apply for an EIN from abroad:

Form SS-4 submitted by fax (+1-855-215-1627) or phone (+1-267-941-1099 for international applicants)
Online EIN is not available if the applicant’s responsible party lacks a U.S. SSN or ITIN
Processing takes 4 to 6 weeks for fax, immediate for phone

Foreign businesses receiving U.S.-source income may also need a W-8BEN-E on file with U.S. payers to claim treaty benefits and avoid 30% withholding.

For full registration guidance, see our foreign business reporting guide.

Question 18

What is an Employer Identification Number (EIN), and does my business need one?

Accepted Answer

An Employer Identification Number (EIN) is a free, nine-digit tax identification number the IRS assigns to businesses and other entities, functioning like a Social Security Number (SSN) for your business. Most U.S. business entities, including LLCs, corporations, partnerships, nonprofits, and sole proprietors with employees, need one to open business bank accounts, file Form 1040 with business income, pay employees, or issue 1099s to contractors.

Your business likely needs an EIN if any of the following apply:

You operate as a corporation, partnership, or multi-member LLC
You have or plan to hire employees (including household employees)
You withhold or pay excise taxes
You have a Keogh plan or other qualified retirement plan
You need to open a U.S. business bank account
A client or payer asks for your federal tax ID to issue a 1099

Sole proprietors with no employees and no plans to incorporate sometimes use their SSN instead. However, many tax professionals recommend obtaining an EIN regardless to keep personal and business finances separate and reduce the risk of identity theft.

Applying from abroad: You cannot apply for an EIN online if the responsible party lacks a U.S. SSN or ITIN. Instead, submit Form SS-4 by fax to +1-855-215-1627 (4 to 6 weeks) or call the IRS international line at +1-267-941-1099 for same-day processing.

EINs do not expire and are assigned permanently to your business. If you close a business and open a new one, you need a new EIN for the new entity.

Question 19

Can a U.S. Expat Form an LLC in the United States While Living Abroad?

Accepted Answer

Yes. U.S. expats can form a single-member or multi-member limited liability company (LLC) in any U.S. state while living abroad. You do not need to be a U.S. resident to be a member, and most states (Delaware, Wyoming, and New Mexico are popular choices) allow 100% foreign-address ownership.

By default, a single-member LLC is a disregarded entity for U.S. tax purposes. That means its income and expenses flow to your personal Form 1040 on Schedule C, and you owe self-employment tax on the net earnings. A multi-member LLC defaults to a partnership and files Form 1065.

You can elect corporate tax treatment by filing:

Form 8832 to be taxed as a C corporation
Form 2553 to be taxed as an S corporation (but S-corp election is blocked if any member is a nonresident alien, including a spouse without a green card)

Key considerations for expat LLC owners:

A U.S. LLC generally does not shield foreign-earned income from self-employment tax unless paired with entity restructuring
You need a U.S. mailing address (registered agent service handles this) and often a U.S. bank account
Applying for an EIN from abroad is done by fax or international phone to the IRS
Some states charge franchise taxes (Delaware’s $300 annual LLC tax, California’s $800 minimum) regardless of whether the LLC generates U.S. income
Foreign-owned single-member LLCs must file Form 5472 with a pro forma 1120 each year

Question 20

Are My Foreign Business Expenses Deductible on My U.S. Expat Tax Return?

Accepted Answer

Yes. Foreign business expenses that are ordinary and necessary for running your trade or business are fully deductible on your U.S. expat tax return, regardless of which country the expense was incurred in. You report them on Schedule C (sole proprietors) or the applicable business return.

Common deductible foreign business expenses include:

Rent for foreign office space or coworking memberships
Utilities, internet, and phone are used for business
Professional services (local accountant, lawyer, translator)
Marketing, website, and software subscriptions
Business travel (flights, lodging, 50% of meals)
Home office (if the space is used regularly and exclusively for business)
Health insurance premiums for self-employed filers
Foreign bank fees tied to the business account

Key rules to watch:

Convert every expense to U.S. dollars using a consistent method (yearly average, monthly average, or spot rate per transaction). Document your method.
Keep receipts and bank records for at least 3 years (6 years if you under-report income by more than 25%)
Entertainment is generally not deductible since the TCJA
VAT or GST paid on business inputs is part of the expense cost

Foreign expenses do not require a U.S. Form 1099 to be deductible, but they do need to be substantiated. A foreign contractor’s payment of $600 or more may trigger Form 1099-NEC if the contractor is a U.S. person, even if services were performed abroad.

Question 21

Is Owning a Foreign Rental Property Considered Self-Employment for U.S. Tax Purposes?

Accepted Answer

In most cases, no. Foreign rental property income is passive income reported on Schedule E, not self-employment income, and is not subject to 15.3% self-employment tax. Two exceptions can flip rentals into active business income: qualifying as a real estate professional and running a short-term rental with substantial services.

Default treatment for foreign rentals:

Gross rents reported on Schedule E
Deductible expenses include mortgage interest, property tax, insurance, repairs, management fees, depreciation, and travel to the property
Depreciation uses the 30-year Alternative Depreciation System (ADS) for foreign residential property (40-year before 2018), regardless of local depreciation rules
Passive loss limits (Section 469) apply; losses may be suspended and carried forward

When rental activity becomes self-employment: ScenarioTreatmentSE taxLong-term rental (30+ days)Schedule E passiveNo SE taxShort-term rental with minimal servicesSchedule E passiveNo SE taxShort-term rental with hotel-like services (daily cleaning, meals)Schedule C business15.3% SE taxReal estate professional (750+ hours, >50% of work time in real estate)Active trade or businessNo SE tax (still Schedule E in most cases)

Short-term rentals (Airbnb, VRBO) with substantial services, such as daily cleaning, concierge, or meals, fall into Schedule C territory. A standard vacation rental with weekly turnover and no hotel-style services stays on Schedule E.

Foreign tax paid on rental income is creditable via Form 1116 in the passive category.
