Self-Employment Tax for Freelancers and Remote Workers Abroad

Introduction

US self-employed individuals living abroad face a burden that employees don't: self-employment (SE) tax of 15.3% applies even when income is excluded under FEIE. This tax funds Social Security (12.4%) and Medicare (2.9%) and cannot be avoided through the Foreign Earned Income Exclusion.

For a freelancer earning $100,000 abroad and excluding it via FEIE, SE tax of approximately $14,130 still applies. This article covers how SE tax works abroad and strategies to reduce it.

How SE Tax Works

Calculation

Self-employment tax is calculated on net self-employment income:

1. Net profit from Schedule C (or Schedule SE)
2. Multiply by 92.35% (reduces base slightly)
3. Apply 15.3% rate (12.4% SS + 2.9% Medicare)

• Income above this: Only 2.9% Medicare applies

• Net self-employment income: $100,000
• SE tax base: $92,350
• SE tax: $14,130 (before any credits)

FEIE Doesn't Help

The Foreign Earned Income Exclusion excludes income from income tax, but SE tax is calculated on gross self-employment income before the exclusion.

**Result:** You can owe SE tax even with zero income tax after FEIE.

Additional Medicare Tax

Income over $200,000 (single) or $250,000 (married filing jointly) incurs additional 0.9% Medicare tax. This is calculated on total income, not FEIE-reduced amount.

Totalization Agreements

What They Are

• Prevent double social security taxation
• Allow combining work credits for benefit eligibility
• Determine which country's system you contribute to

Countries with Agreements

Australia, Austria, Belgium, Brazil, Canada, Chile, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovak Republic, Slovenia, South Korea, Spain, Sweden, Switzerland, United Kingdom, Uruguay.

How They Work

• Employees and self-employed: Pay into system where work is performed
• Temporary assignments (under 5 years): May remain in home country system

• Proves you're covered under US system (so exempt from foreign)
• OR proves you're covered under foreign system (so exempt from US)
• Apply through Social Security Administration (Form SSA-7004)

Self-Employed Specifics

For self-employed individuals, totalization rules vary:

• Generally pay into country where you work
• If less than 5 years: May elect to stay in US system
• Certificate of Coverage needed for exemption

• Pay US SE tax on worldwide self-employment income
• May also owe foreign social contributions (double taxation)

Strategies to Reduce SE Tax

1. Form Foreign Corporation

Operating through a foreign corporation can convert SE income to wages and dividends:

• Form corporation in foreign country
• Corporation employs you (pays wages)
• Corporation pays into foreign social security
• You receive salary (subject to foreign social security, not US SE tax)

• PFIC rules may apply to investment income
• CFC rules may trigger current US taxation
• Requires proper substance and compliance
• Professional guidance essential

2. Work in Treaty Country

Moving to a totalization agreement country and properly establishing coverage there eliminates US SE tax:

**Steps:** 1. Move to treaty country 2. Register as self-employed locally 3. Pay into local social security system 4. Obtain certificate showing foreign coverage 5. US SE tax no longer applies

• Portugal (lower rates than US)
• UK (National Insurance)
• Germany (complex but possible)

3. S Corporation (Limited Effectiveness)

Domestic S corporations can reduce SE tax through reasonable salary:

• S corp pays you "reasonable salary" (subject to SE tax)
• Remaining profit distributed as dividends (no SE tax)

• "Reasonable salary" scrutinized by IRS
• Foreign income complications
• State taxes may apply

4. Retirement Contributions

Self-employed retirement contributions reduce taxable income but don't directly reduce SE tax base. However, they provide long-term benefits:

• **Solo 401(k):** Up to $69,000 (2025) combined contribution
• **SEP-IRA:** Up to 25% of net self-employment earnings
• **SIMPLE IRA:** Up to $16,500 + employer match

5. Health Insurance Deduction

Self-employed health insurance premiums are deductible from income tax (not SE tax), reducing overall burden.

Filing Requirements

Schedule SE

All self-employed individuals file Schedule SE with Form 1040:

• Calculate SE tax
• Report along with Form 1040

Form 2555

If claiming FEIE:

• File Form 2555
• FEIE reduces income tax, not SE tax
• Net result: May owe SE tax with no income tax

International Forms

If using foreign structures:

• Form 5471 (foreign corporation)
• Form 8865 (foreign partnership)
• FBAR (foreign accounts)
• Form 8938 (FATCA)

Key Takeaways

• SE tax (15.3%) applies to self-employment income even with FEIE
• Totalization agreements with 30 countries can eliminate US SE tax
• Working through foreign corporation requires careful planning but may reduce SE tax
• Certificate of Coverage proves exemption from one country's system
• Retirement contributions don't reduce SE tax but provide other benefits

Next Steps

2. If yes, investigate obtaining Certificate of Coverage
3. Consider foreign corporation structure (with professional guidance)
4. Maximize retirement contributions to offset income tax
5. Consult expat tax professional familiar with SE tax planning
