What is the rule?
The tax code limits who can own shares in an S corporation. Shareholders must generally be US citizens or residents, certain trusts, estates or exempt organizations. A nonresident alien is expressly excluded. There is no minimum: one share held by a nonresident alien is enough to end the election.
The rule looks at tax residence, not nationality. A foreign national who is a US resident for tax, through a green card or the substantial presence test, can be a shareholder.
What happens if a nonresident becomes a shareholder?
The S election terminates automatically on the day the ineligible person becomes a shareholder. From that day the company is a C corporation: it pays 21% corporate tax, files Form 1120, and generally cannot re-elect S status for five years without IRS consent. The year is split into a short S year and a short C year.
When does this catch people out?
- A shareholder moves abroad and stops being a US tax resident. A US citizen who moves abroad remains eligible, because citizens are always eligible. A resident alien who leaves may become a nonresident alien and end the election.
- A shareholder's spouse is a nonresident alien in a community property state. The spouse may hold a community property interest in the shares, making them a shareholder.
- Shares are transferred by sale, gift or inheritance to a foreign person.
- An LLC with a foreign member files Form 2553 without realizing the member makes it ineligible.
Can a terminated election be saved?
If the termination was inadvertent, the IRS can treat the election as continuing, provided the problem is corrected within a reasonable time after discovery and the shareholders agree to any adjustments required. Relief is requested through a private letter ruling, which has a fee, or in some cases under simplified procedures. Acting quickly helps.
What do foreign owners use instead?
- An LLC under the default rules. A single-member LLC is disregarded, and a multi-member LLC is a partnership. Profit passes through without corporate tax. See whether foreign-owned US LLCs pay US tax.
- A C corporation. Any mix of owners is allowed, but the company pays 21% and dividends face withholding. See LLC or C corp for a foreign founder.
