Expat Tax

What is Self-Employment Tax Abroad?

The 15.3% Social Security and Medicare tax that self-employed US citizens owe even when living and working outside the United States.

Definition

US citizens and resident aliens who are self-employed abroad generally must pay US self-employment tax (15.3%) on their net self-employment income, even if they qualify for the Foreign Earned Income Exclusion. The FEIE only excludes income from federal income tax, not from self-employment tax. Totalization Agreements with certain countries may provide relief by allowing the self-employed individual to pay only into the host country's social insurance system.

Who Needs to Know This?

Self-employed US citizens and resident aliens working abroad, including freelancers, consultants, and business owners operating in foreign countries.

Key Deadline

Filed with annual tax return on Schedule SE; quarterly estimated payments recommended

Potential Penalties

Underpayment penalties for insufficient estimated tax payments
