What Is the Self-Employment Tax for Expats?

U.S. self-employment tax (SECA) is 15.3% of your net earnings from self-employment. That's 12.4% for Social Security (OASDI) and 2.9% for Medicare (HI). Unlike income tax, this tax applies regardless of where you live — and the Foreign Earned Income Exclusion (FEIE) does not eliminate it.

The 15.3% Rate — What It Covers

Social Security (OASDI) 12.4%
Medicare (Hospital Insurance) 2.9%
Total Self-Employment Tax 15.3%

📌 Key Threshold: You must file Schedule SE and pay self-employment tax if your net earnings are $400 or more in a tax year.

Why FEIE Doesn't Eliminate Self-Employment Tax

The Foreign Earned Income Exclusion lets you exclude up to a certain amount of foreign earned income from U.S. income tax — but it has no effect on self-employment tax. You still owe 15.3% on net earnings over $400.

Provision	Affects Income Tax?	Affects Self-Employment Tax?
Foreign Earned Income Exclusion (FEIE)	✅ Yes	❌ No
Foreign Tax Credit (FTC)	✅ Yes	❌ No
Totalization Agreement Exemption	—	✅ Yes

🔑 Key Takeaway: FEIE and FTC can't help you avoid self-employment tax. A totalization agreement is the only way to eliminate 15.3% U.S. SE tax while living abroad.

📌 Source: IRS — Self-Employment Tax (SECA) guidelines. The Social Security wage base for 2026 is $184,500. Learn more on IRS.gov

What Is a Totalization Agreement?

A totalization agreement is a bilateral treaty between the United States and another country that prevents double taxation of Social Security and Medicare contributions. For self-employed expats, it means you pay into only one country's social security system — either the U.S. or your host country — not both.

📌 Purpose 1: Eliminate Double Taxation

If you're self-employed in a country with an agreement and paying into its social security system, you're exempt from U.S. self-employment tax on that income.

📌 Purpose 2: Combine Social Security Credits

You can combine credits from both countries to qualify for Social Security benefits if you don't have enough credits in one country alone.

💡 Good news for expats: the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) were repealed by the Social Security Fairness Act — for benefits payable from 2025 onward, a foreign pension no longer reduces your U.S. benefit the way it once did.

How Totalization Agreements Work for Self-Employed Expats

Under most totalization agreements, the general rule for self-employed individuals is:

"You are covered by the social security system of the country where you reside and work."

If you live in an agreement country and pay into that country's social security system, you owe $0 in U.S. self-employment tax.
If you live in an agreement country but do not pay into that country's system, you still owe 15.3% U.S. SE tax.
If you live in a country without an agreement, you owe 15.3% U.S. SE tax plus whatever your host country requires.

💡 The Detached Worker Rule: For employees (not self-employed), there's a 5-year rule allowing them to stay in the U.S. system temporarily. Self-employed individuals don't have this option — you must use the host country's system from day one.

Totalization Agreement vs. Tax Treaty — What's the Difference?

Aspect	Totalization Agreement	Tax Treaty
Covers	Social Security & Medicare	Income tax
Affects SE Tax?	✅ Yes	❌ No
Requires Certificate of Coverage?	✅ Yes	—
Combines Social Security Credits?	✅ Yes	—

⚠️ Important: An income tax treaty does not protect you from self-employment tax. Totalization agreements are separate and operate independently. Income tax treaties can, however, affect how foreign tax credits offset the 3.8% Net Investment Income Tax.

Which Countries Have Totalization Agreements With the U.S.?

The United States has totalization agreements with 30 countries as of 2026. If you're self-employed and paying into the social security system of any of these countries, you're generally exempt from U.S. self-employment tax.

✅ Australia

✅ Austria

🌍 Total: 30 countries with active totalization agreements as of 2026.

📅 Upcoming: The U.S.–Romania totalization agreement enters into force on September 1, 2026, making Romania the 31st agreement country. If you work in Romania, check the SSA's agreement list after that date to see whether the exemption applies to you.

How to Verify Your Country's Agreement Status

The Social Security Administration maintains an official list of all active agreements. To verify your country's status:

Visit the SSA International Agreements Overview page.
Select your country from the list of agreement countries.
Review the specific provisions for self-employed individuals.
Check the effective date and any special rules that may apply.

⚠️ Important: Even if your country has an agreement, you must be paying into that country's social security system to qualify for exemption from U.S. self-employment tax. The agreement alone is not enough.

What If Your Country Doesn't Have a Totalization Agreement?

If your host country does not have a totalization agreement with the U.S., you must pay 15.3% U.S. self-employment tax on your net earnings — and you'll also owe whatever social security charges your host country requires. This creates a double taxation problem.

🔴 The Double Tax Problem

If you're a self-employed U.S. citizen in a non-agreement country like Mexico, Thailand, or Singapore, you'll owe:

15.3% to the U.S. (Social Security + Medicare)
Host country social security contributions (varies by country)
Total burden can reach 25%–40% of your net income

What You Can Do If There's No Agreement

💡 Option 1: Restructure Your Business Entity

Form an S-corporation or LLC
Pay yourself a reasonable salary
Distribute remaining profit as dividends (not subject to SE tax)
Can reduce your SE tax liability significantly

⚠️ Consult a CPA — this requires careful planning

💡 Option 2: Consider Relocating

Move to a country with a totalization agreement
Popular options: Spain, UK, Germany, Canada
Eliminate 15.3% U.S. SE tax entirely
May also reduce your overall tax burden

💡 Use our calculator above to compare scenarios

💡 Option 3: Consult a Professional

Tax laws are complex and change frequently. A qualified expat tax professional (CPA or Enrolled Agent) can help you:

Determine the most tax-efficient structure for your situation
Identify any available foreign tax credits or deductions
Ensure compliance with both U.S. and host country tax laws
Plan for future tax changes and requirements

📝 Real-World Example: Freelancer in Mexico

Scenario: Mexico (No Agreement)

Net income: $100,000
U.S. SE tax: $15,300 (15.3%)
Mexican IMSS: ~$9,700 (independents typically pay ~9.7% of an assessed base; varies)
Total: ~$25,000 (25.0% effective rate)

Compare: Spain (With Agreement)

Net income: $100,000
U.S. SE tax: $0 (exempt)
Spain RETA: ~$28,000 (28%)
Total: ~$28,000 (28% effective rate)

💡 Key Insight: Even though Spain's social security rate (28%) is higher than Mexico's, you save $15,300 in U.S. SE tax — and you avoid the complexity of double taxation. The total tax burden may be similar, but you're compliant with both systems.

No-Agreement Playbook — 3 Ways to Cut Double Social Security Costs

1️⃣ Elect S-Corp Status (US LLC)

A reasonable salary from your S-corp is subject to SE tax, but remaining distributions are not. This can legally reduce your 15.3% burden — though the salary must be defensible, and your host country may tax the distributions differently.

2️⃣ Convert Earnings to Dividends

Income paid as dividends from a foreign company is generally not subject to U.S. self-employment tax. This works best when a local business entity is a natural fit for how you actually work.

3️⃣ Relocate to an Agreement Country

Countries with active agreements (like Portugal, Spain, or Uruguay) offer a clean path to exemption once you're paying into their system. Treat relocation as a long-term strategy, not a quick fix.

⚠️ Important: If you're in a non-agreement country, you may still be able to avoid double taxation through proper planning. Do not ignore your U.S. filing obligations — penalties and interest can be significant. Consult a professional.

How to Apply for a Certificate of Coverage

A Certificate of Coverage is the official document that proves you're covered by your host country's social security system under a totalization agreement. Without it, you cannot claim exemption from U.S. self-employment tax.

📄 How to Request a Certificate of Coverage

There is no paper application form for a Certificate of Coverage. Self-employed individuals and employers request one online through the SSA's official Certificate of Coverage portal at opts.ssa.gov, which asks for your personal information (name, date of birth, Social Security number), your country of residence, and details of your self-employment activity. You can also apply by mail or fax by submitting the same information directly to the SSA's Office of International Programs.

🖥️ Request Online at opts.ssa.gov(Official SSA website)

Step-by-Step Application Process

Determine Eligibility

Confirm your host country has a totalization agreement with the U.S.

Complete Your Online Request (or Mail/Fax)

Open the Certificate of Coverage request form at opts.ssa.gov
Fill in your personal information (name, SSN, address)
Provide host country details and employer/business information
Include the period of coverage requested

Submit to the Social Security Administration

Submit online at opts.ssa.gov, or mail/fax your request to SSA
Include any supporting documentation required
Processing time: SSA advises allowing up to 90 business days
Keep a copy for your records

Receive Your Certificate of Coverage

SSA will issue the Certificate of Coverage
Review it for accuracy (dates, country, coverage details)
Attach it to your Form 1040 when filing
Keep the original for your records

What to Do After Receiving Your Certificate of Coverage

Attach the certificate to your Form 1040 — Include it with your U.S. tax return
Fill out Schedule SE correctly — Enter "Exempt, see attached statement" in the appropriate section
Do not pay the 15.3% SE tax — The certificate proves you're exempt
Keep a copy for future years — The certificate may cover multiple tax years
Notify your host country — Ensure they know you're covered by their system

Common Mistakes to Avoid

❌ Applying for the certificate after filing your return

❌ Assuming the agreement automatically exempts you

❌ Not paying into the host country's system

❌ Using the certificate for income tax (it only covers SE tax)

💡 Pro Tip: Apply for your Certificate of Coverage as early as possible — ideally before tax season. SSA advises allowing up to 90 business days for processing, and you'll need the certificate to file your return correctly.

Frequently Asked Questions

Get answers to the most common questions about totalization agreements and self-employment tax for expats.

What is a totalization agreement?+

A totalization agreement is a bilateral treaty between the United States and another country that prevents double taxation of Social Security and Medicare contributions. For self-employed expats, it means you pay into only one country's social security system — either the U.S. or your host country — not both. This eliminates the 15.3% U.S. self-employment tax if you're paying into your host country's system.

Do I have to pay U.S. self-employment tax if I live abroad?+

Yes, generally. U.S. citizens and green card holders must pay U.S. self-employment tax (15.3%) on net earnings from self-employment over $400, regardless of where they live. However, if your host country has a totalization agreement and you're paying into that country's social security system, you may be exempt from U.S. self-employment tax. Use our calculator above to check your specific situation.

Which countries have totalization agreements with the U.S.?+

The U.S. has totalization agreements with 30 countries as of 2026: 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, and Uruguay.

Romania's agreement enters into force on September 1, 2026 — the 31st country. See the full list with host social security rates in the instant answer table above.

Does FEIE eliminate self-employment tax?+

No. The Foreign Earned Income Exclusion (FEIE) only applies to income tax, not self-employment tax. Even if you exclude all your foreign earned income using the FEIE, you still owe 15.3% self-employment tax on net earnings over $400 unless you qualify for an exemption under a totalization agreement. This is a common misconception that can lead to costly tax surprises.

How do I claim exemption from self-employment tax?+

To claim exemption from U.S. self-employment tax:

Verify your host country has an agreement with the U.S.
Confirm you're paying into your host country's social security system
Obtain a Certificate of Coverage from the Social Security Administration (request it online at opts.ssa.gov)
Attach it to your Form 1040 with a statement on Schedule SE that you're exempt under the totalization agreement

See the full step-by-step guide in the Certificate of Coverage section above.

What if my country has no totalization agreement?+

If your host country does not have a totalization agreement with the U.S., you must pay 15.3% U.S. self-employment tax on your net earnings — and you'll also owe whatever social security charges your host country requires. This can result in double taxation.

Options include restructuring your business entity (S-corp or LLC), considering relocation to an agreement country, or consulting a tax professional. See the "What If Your Country Doesn't Have a Totalization Agreement?" section above for detailed strategies.

What is a Certificate of Coverage?+

A Certificate of Coverage is an official document issued by the U.S. Social Security Administration that proves you're covered by your host country's social security system under a totalization agreement. It exempts you from paying U.S. self-employment tax by showing you've been assigned to your host country's system. You must obtain this certificate and attach it to your Form 1040.

Request online at opts.ssa.gov

How much is self-employment tax for expats?+

The U.S. self-employment tax rate for expats is 15.3% on net earnings from self-employment over $400. This breaks down as 12.4% for Social Security (OASDI) and 2.9% for Medicare (HI). High earners may also owe an additional 0.9% Medicare surtax on income above $200,000 (single) or $250,000 (married filing jointly).

The Social Security wage base for 2026 is $184,500. Income above this amount is still subject to Medicare tax.

What is the territoriality rule?+

The territoriality rule is a principle in international tax law stating that work is generally taxed where it's physically performed. Under totalization agreements, self-employed individuals are typically covered by the social security system of the country where they reside and work. This is why U.S. expats in agreement countries can often pay into their host country's system instead of the U.S., eliminating 15.3% self-employment tax.

How do totalization agreements affect self-employment tax?+

Totalization agreements eliminate double taxation of self-employment income by determining which country's social security system covers you. If you're in an agreement country and paying into that country's system, you're exempt from U.S. self-employment tax entirely. This can save you up to 15.3% of your net earnings — a significant amount for many self-employed expats. Use our calculator above to estimate your savings.

Self-Employment Tax Calculation

Formula: Net Income × 15.3% (12.4% Social Security + 2.9% Medicare). For simplicity this calculator applies 15.3% to the net income you enter. On an actual Schedule SE, the IRS applies the combined 15.3% rate to 92.35% of net earnings — so your real filing figure is slightly lower (about 7.65% less than this estimate).

⚠️ If net income is below $400, no self-employment tax is owed.

📌 Additional 0.9% Medicare surtax applies to income above $200,000 (single) or $250,000 (married filing jointly).

Country Agreement Status Check

Logic: If the selected country is in our verified list of 30 agreement countries, the calculator flags it as "agreement exists."

📌 Data sourced from the SSA International Agreements Overview (updated 2026).

Exemption Eligibility Determination

Logic: A user is eligible for exemption if:

Country has an agreement
User is paying into host country's social security system
User obtains a Certificate of Coverage from SSA

📌 If eligible, U.S. self-employment tax owed = $0.

Savings Calculation

Formula: Savings = Net Income × 15.3% (if exempt)

📌 If not exempt, savings = $0 (you owe the full 15.3%).

📌 Host country social security contributions are not included in the savings calculation — they vary widely and are shown separately for reference.
