Who Must Pay Self-Employment Tax?
If you are living abroad and you are a self-employed U.S. citizen or resident you generally are subject to the self-employment tax. This is a social security and Medicare tax on net earnings from self-employment of $400 or more a year. Your net self-employment income is used to figure your net earnings from self-employment. Net self-employment income usually includes all business income less all business deductions allowed for income tax purposes. Net earnings from self-employment is a portion of net self-employment income. This amount is figured on
Schedule SE. The actual self-employment tax is figured on net earnings from self-employment.
Effect of Foreign Earned Income Exclusion
You must take all of your self-employment income into account in figuring your net earnings from self-employment, even income that is exempt from income tax because of the
foreign earned income exclusion.
Example:
You are in business abroad as a consultant and qualify for the foreign earned income exclusion. Your foreign earned income is $95,000, your business deductions total $27,000, and your net profit is $68,000. You must pay self-employment tax on all of your net profit, including the amount you can exclude from income.
