Many American freelancers abroad use the Foreign Earned Income Exclusion to cut their income tax to zero, then find a separate bill on their return. That bill is self-employment tax abroad, and the exclusion does not reduce it. This guide explains why, as of September 2026, and where a real exception exists.
We checked every rule below against current IRS and Social Security Administration pages rather than secondary summaries. Also, tax outcomes vary by person, so confirm your own case with the IRS, the SSA or a licensed tax professional.
Why Self-Employment Tax Abroad Survives the FEIE
Self-employment tax is the Social Security and Medicare tax that freelancers and sole proprietors pay. According to the IRS self-employment tax page, the rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare. It generally applies once net self-employment earnings reach $400, as IRS Topic 554 explains.
The FEIE, claimed on Form 2555, lets qualifying Americans abroad exclude foreign earned income from income tax. To qualify, you generally need to pass the physical presence or bona fide residence test, which we cover in our guide to counting the 330 days.
However, the exclusion stops at income tax. The IRS page on self-employment tax for businesses abroad says you must count all self-employment income in net earnings, even if you excluded some or all of it under the FEIE. As a result, Schedule SE runs separately from Form 2555.
What the Bill Looks Like
Consider $80,000 of net self-employment earnings. Because Schedule SE applies the tax to 92.35% of net earnings, the taxable base is $73,880. So at 15.3%, the bill comes to about $11,304, even if the FEIE erased all income tax on the same money.
There is a partial offset. For example, Topic 554 lets you deduct one-half of your self-employment tax when you figure adjusted gross income. Schedule SE calculates that deduction for you, so you don’t need to request it.
Higher earners hit a cap on part of the tax. For 2026, the SSA contribution and benefit base is $184,500, so the 12.4% Social Security portion stops above that level. However, the 2.9% Medicare portion has no such cap.
Common Mistakes With Self-Employment Tax Abroad
The first mistake is assuming tax software applied the FEIE to everything. In practice, a return can show zero income tax and still owe self-employment tax, so read Schedule SE line by line before you file.
The second mistake is claiming a totalization exemption without the paperwork. For instance, living in an agreement country does not help on its own; you need the certificate of coverage from that country’s agency.
The third mistake is forgetting that the rules cut both ways. If you hold a certificate from an agreement country, you may owe contributions there instead, so budget for the local system as well.
The Main Exception: Totalization Agreements
The US has Social Security totalization agreements with a set list of countries to prevent double contributions. Under these agreements, only one country’s system generally covers a self-employed person for the same work. The IRS totalization agreements page explains how this works for US tax.
Coverage is limited, though. The SSA’s international agreements page lists 31 countries with agreements in force. Portugal, Spain, Germany, France, the United Kingdom, Canada, Japan and South Korea are on it, while Mexico, Colombia, Thailand, Indonesia and Vietnam are not.
| Category | Examples | Relief from US self-employment tax? |
|---|---|---|
| Countries with a US totalization agreement | Portugal, Spain, Germany, France, United Kingdom, Canada, Japan, South Korea | Possibly, with a certificate of coverage |
| Popular nomad bases without an agreement | Mexico, Colombia, Thailand, Indonesia, Vietnam | Generally no; the full 15.3% still applies |
The US signs new agreements from time to time. Therefore, check the SSA list for your country of residence before you plan around either answer.
How the Certificate of Coverage Works: Portugal Example
Portugal draws many American freelancers and has an agreement with the US. According to the SSA’s US–Portugal agreement pamphlet, Portugal’s system generally covers self-employed people who live there, instead of the US system.
To prove this, the SSA also says to write to the regional Portuguese social security office. The request should include your name, date of birth, nationality, both countries’ social security numbers, and the nature, dates and business address of your self-employment.
Once you receive the certificate, the SSA says to attach a photocopy to your US tax return each year. Without it, you have no evidence for a reduced or zero figure on Schedule SE, so keep copies with your records.
Other agreement countries follow a similar process. Still, the office and required details differ, so read the SSA pamphlet for your specific country.
If Your Country Has No Agreement
Freelancers in a non-agreement country should plan for the full 15.3% rate. It applies to 92.35% of net earnings. In other words, budget for it the same way you budget for income tax, and file Schedule SE with Form 1040 even when the FEIE zeroes out income tax.
Quarterly estimated payments should cover this tax too. Many nomads already pay estimates for income tax, but they often leave out the self-employment portion. For payment options without a US bank, see our guide to paying IRS quarterly taxes from abroad.
It also helps to treat the two taxes as separate budgets. The FEIE may reduce or remove your income tax, while self-employment tax follows its own calculation based on net earnings.
Finally, keep your records organised by year. For example, save each Schedule SE, each certificate of coverage and each estimated payment receipt together. That way, you can answer an IRS letter quickly even from abroad.
Frequently Asked Questions
Does self-employment tax abroad go away once the FEIE applies?
No, because the FEIE only reduces income tax. The IRS requires you to count all net self-employment earnings, including excluded income, so Schedule SE still applies.
Which countries let self-employed nomads avoid US self-employment tax?
Only countries with a US totalization agreement in force, which numbered 31 on the SSA list when we checked. For example, Portugal, Spain, Germany and Canada qualify, while Mexico, Thailand and Colombia do not.
How do I claim the totalization exemption?
First, request a certificate of coverage from the social security agency in your country of residence, following the SSA pamphlet for that country. Then attach a copy of the certificate to your US tax return each year the exemption applies.
