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%
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 |

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.
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.
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 | — |

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.
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.

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
💡 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
💡 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
- Net income: $100,000
- U.S. SE tax: $15,300 (15.3%)
- Mexican IMSS: ~$15,000 (varies)
- Total: ~$30,300 (30.3% effective rate)
- Net income: $100,000
- U.S. SE tax: $0 (exempt)
- Spain RETA: ~$28,000 (28%)
- Total: ~$28,000 (28% effective rate)

Frequently Asked Questions
Get answers to the most common questions about totalization agreements and self-employment tax for expats.
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.
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.
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.
See the full list with host social security rates in the instant answer table above.
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.
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 (Form SSA-1694-PDF)
- 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.
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.
A Certificate of Coverage (Form SSA-1694-PDF) 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.
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.
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.
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.

Methodology — How We Calculate Your Self-Employment Tax Liability
Our calculator uses current 2026 tax data, official Social Security Administration (SSA) totalization agreements, and IRS self-employment tax guidelines. Here's exactly how we calculate your results.
Self-Employment Tax Calculation
Formula: Net Income × 15.3% (12.4% Social Security + 2.9% Medicare)
âš ï¸ 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.
