Can a nonresident alien own an S corporation?
The short answer is no: a nonresident alien cannot be a direct shareholder of an S corporation. It is a common question because the S corporation is such a popular structure for small US businesses, but the eligibility rules are unusually strict on this point, and getting it wrong does not just create a problem for the individual — it ends the corporation's S status entirely. This guide explains the rule, the narrow exception, and the alternatives.
The rule and why it bites hard
The tax law sets out exactly which shareholders an S corporation is permitted to have — broadly US individuals, certain trusts and estates, and certain exempt organisations — and a nonresident alien is not on the list. The consequence is severe and automatic: if a nonresident alien becomes a shareholder, the corporation's S election terminates as of the date that person acquired the shares, and the corporation reverts to being taxed as a C corporation from that point. There is no partial treatment and no grace period built into the rule itself. That is why the restriction is treated so carefully when S corporation shares change hands, and why it is one of the eligibility conditions confirmed on Form 2553.
Resident alien is different
An important distinction: the bar is on non-resident aliens. A resident alien — someone who holds a green card or meets the substantial presence test based on days of US physical presence — is treated broadly like a US person for this purpose and can be an S corporation shareholder. So the question is not about citizenship but about US tax residency. A foreign national who becomes a US tax resident may hold S corporation shares; the same person, before establishing residency, may not. This is a frequent point of confusion, and it turns entirely on the residency tests rather than on nationality.

There is one indirect route, and it is genuinely narrow. Since a change in the law that took effect in 2018, a nonresident alien may be a potential current beneficiary of an electing small business trust (ESBT) that holds S corporation stock. This is an interest through a trust of a specific kind, subject to that trust's own rules — not the same thing as a nonresident alien holding shares directly. It is a considered planning structure rather than a workaround, and it does not change the basic rule that direct ownership by a nonresident alien is not allowed.
What non-residents use instead
A nonresident who wants to run or invest in a US business generally reaches for a structure other than the S corporation. Common choices are a C corporation, or an LLC taxed as a partnership or as a C corporation — the trade-offs of which are set out in LLC versus C corporation and, for the formation mechanics, US LLC formation for non-residents. A foreign corporation operating in the US is in yet another regime, filing Form 1120-F. The right answer depends on what the non-resident is trying to achieve — the point is simply that the S corporation is off the table for direct ownership, so the planning starts from the alternatives.

Questions people also ask
Can a nonresident alien be an S corporation shareholder?
No — not as a direct shareholder. The tax law lists the shareholders an S corporation may have, and a nonresident alien is not among them. If a nonresident alien becomes a shareholder, the corporation's S election terminates as of that date and it reverts to being taxed as a C corporation. This is one of the most rigid rules in the S corporation regime.
Is there any way a nonresident alien can be connected to an S corporation?
Indirectly, and narrowly. Since a 2018 change in the law, a nonresident alien may be a potential current beneficiary of an electing small business trust that holds S corporation stock. That is an interest through a specific type of trust, not direct share ownership, and it comes with its own conditions. It does not open the door to a nonresident alien simply holding shares.
What structure should a nonresident use instead?
A nonresident who wants a US business commonly uses a C corporation, or an LLC taxed as a partnership or as a C corporation, rather than an S corporation. Each has different tax and filing consequences, so the choice depends on the goals. A resident alien — someone with a green card or who meets the substantial-presence test — is not subject to this restriction and can be an S corporation shareholder.
