958 / Can U.S. individuals employed in a foreign country receive U.S. Social Security credit?

In some cases, a U.S. individual will continue to earn U.S. Social Security credit if liable for Social Security and Medicare taxes on amounts earned while performing services as an employee in a foreign country. The IRS has issued guidance that provides that Social Security and Medicare taxes continue to apply to wages paid for services performed by a U.S. individual abroad if any of the following are true:

(1)     The individual is working for a U.S. employer,

(2)     The individual performs services in connection with a U.S. aircraft or vessel and the individual has (a) entered into an employment contract in the U.S. or (b) the vessel or aircraft touches down at a U.S. port while the individual is employed on it,

(3)     The individual is working in a country with which the U.S. has entered a Social Security agreement providing that the foreign earned income is subject to U.S. Social Security and Medicare taxes, or

(4)     The individual is working for a foreign affiliate (a foreign entity in which the U.S. employer has at least a 10 percent interest) of a U.S. employer under a voluntary agreement (under IRC Section 3121(l)) entered into by that employer and the U.S. Treasury Department.¹

The IRS guidance further provides that an individual is “working for a U.S. employer” for purposes of (1), above, if the individual is working for (a) the U.S. government (or instrumentality thereof), (b) another individual who is a U.S. resident, (c) a partnership in which at least two-thirds of the partners are U.S. residents, (d) a trust, in which all of the trustees are U.S. residents or (e) a corporation organized in the U.S., or in any U.S. state (including D.C., the Virgin Islands, Guam, American Samoa and the Northern Mariana Islands).²

A U.S. employer who voluntarily enters into an agreement to extend Social Security coverage to its employees working in a foreign country is liable for the entire amount of the covered employees’ Social Security taxes that would otherwise apply under Sections 3101 and 3111 if those employees were employed domestically.³

The IRS has advised that U.S. individuals who are working in a country with which the U.S. has entered a Social Security agreement providing that the individual’s income will not be subject to U.S. Social Security taxes obtain a statement from the relevant agency in the foreign country stating that the individual’s income is subject to Social Security coverage in that foreign country.

The U.S. Social Security Administration (SSA) will issue determinations that a U.S. individual’s income is subject only to U.S. Social Security taxes if the employer contacts the SSA and provides certain basic identifying information about that individual and his or her employment abroad.
