Entity & Tax

Which entities can you actually own? The S corporation trap, precisely

Most entity guides are written for citizens and never say so. One of their standard recommendations carries a restriction that can quietly disqualify a non-citizen owner, and the restriction turns on tax residency, not on your visa.

Generic entity advice compares sole proprietorships, partnerships, LLCs, S corporations, and C corporations on liability, taxation, and paperwork. All of that comparison is real. What it almost never mentions is that one of the five has an ownership restriction written into the tax code, and that the restriction is about people like the readers of this library.

An S corporation is a corporation, or an eligible LLC, that elects pass-through taxation under Subchapter S. The election has conditions, and one of them is about who the shareholders are: the statute does not permit a nonresident alien shareholder. One ineligible shareholder does not just create a problem for that shareholder. It ends the election for the company, which is why the guides that do mention this treat it as a company-level risk.

Here is the part that rewards a careful read: "nonresident alien" is a TAX definition, not an immigration one. Tax residency is determined by its own tests, including the green card test and the substantial presence test. Many visa holders who live and work in the United States are resident aliens for tax purposes even though their immigration status is temporary. Which means the question "can I be an S corporation shareholder?" is not answered by naming your visa. It is answered by determining your tax residency, this year and in the years ahead, including any year a treaty election or a long absence changes the answer.

That last clause is where the trap actually lives. Eligibility is not a one-time gate. A shareholder whose tax residency changes after the election can end the company's S status from the outside. A company with a non-citizen shareholder who ever intends to leave, or whose household files in a way that affects residency, is carrying a risk that a company owned by citizens is not.

The other entities carry no equivalent status-based bar in the tax code. C corporations may have any shareholders. Partnerships and LLCs may generally have non-citizen members, with their own tax consequences, including withholding obligations that surprise people. And none of this touches the separate question this library treats elsewhere: owning an entity and working for it are different acts, and the second one is where immigration rules concentrate.

So the honest sequence for a non-citizen choosing an entity is: first the ownership eligibility question, answered from tax residency with a professional who determines it properly; then the liability and taxation comparison everyone else starts with; then the employment and control questions if you intend to work in the business. The generic guides start at step two because their readers can. You start at step one because the statute says so.
