Form 2553 is the form a corporation files to be taxed as an S corporation. The election itself comes from the tax code, at IRC § 1362(a). Filing the form is how a company tells the IRS it wants that treatment.
Founders hear about S corporations constantly, usually as a way to change how the owner's profits are taxed. So they go looking for the form, fill it in, and mail it. Then the election is rejected, or worse, it is accepted and later unwound.
The reason is almost always the same. Form 2553 is not really a choice you make. It is a test the company has to pass first, and one of the conditions has nothing to do with the company at all. It is about who owns it. If a single shareholder is a nonresident alien, the company is not eligible, and no amount of correct paperwork changes that.
What the rules actually require
To elect S corporation status, the company has to meet all of the following conditions at the same time.
No nonresident alien shareholder. This is the condition that stops most foreign founders. IRC § 1361(b)(1)(C) says a small business corporation cannot "have a nonresident alien as a shareholder." There is one narrow exception, and it sits in a different subsection. Under IRC § 1361(c)(2)(B)(v), the rule that treats each potential current beneficiary of an electing small business trust (ESBT) as a shareholder "shall not apply for purposes of subsection (b)(1)(C)." So a nonresident alien can be a potential current beneficiary of an ESBT without disqualifying the company. Outside of that, a nonresident alien holding shares makes the company ineligible.
Read the word "alien" carefully. The test is not your passport. It is your tax residence, which the IRS decides with the green card test and the substantial presence test. A foreign citizen who passes either test is a resident alien, and a resident alien is allowed to hold S corporation shares. A U.S. citizen who lives abroad is still a U.S. citizen, and is also allowed. The line runs exactly where our U.S. person page draws it.
100 shareholders or fewer. The company cannot have more than 100 shareholders. Under IRC § 1361(c)(1), a husband and wife (and their estates) count as one shareholder, and all members of a family (and their estates) count as one shareholder, which raises the real ceiling for family businesses.
A domestic corporation, with only individuals, estates and certain trusts as shareholders. IRC § 1361(b)(1) opens with "a domestic corporation which is not an ineligible corporation," and subparagraph (B) bars any shareholder "who is not an individual," apart from estates, the trusts listed in § 1361(c)(2) and the exempt organizations listed in § 1361(c)(6). A holding company, a partnership or a foreign parent sitting on the cap table disqualifies the election on its own.
One class of stock. The company can have only one class of stock. Differences in voting rights are ignored for this rule, so you can give some shares votes and others none and still have one class. What you cannot do is give some shares a better claim on profits or on money paid out when the company closes.
The election has to be filed on time. Form 2553 must be filed either:
- at any time during the tax year before the year you want the election to start, or
- no more than 2 months and 15 days after the beginning of the tax year you want it to start.
The IRS instructions say how to count the two months: the period "begins on the day of the month the tax year begins and ends with the close of the day before the numerically corresponding day of the second calendar month following that month." So if your tax year begins on 1 January 2026, the two months run out at the close of 28 February, and fifteen more days takes you to 15 March 2026. If your tax year begins on 1 June 2026, the two months run out at the close of 31 July, and the deadline is 15 August 2026. Miss it, and under IRC § 1362(b)(3) the election normally takes effect for the following tax year instead.
There is relief for a late filing. Under Rev. Proc. 2013-30, a company that filed late can still get the election back-dated if it can show reasonable cause for missing the deadline and can show it reported consistently as an S corporation in the meantime. The relief has its own outside date: the instructions require that Form 2553 be filed within 3 years and 75 days of the effective date the company is asking for. Relief is for lateness only. It does not fix a company that was never eligible.
🇺🇸 If the IRS counts you as a U.S. person
The door is open. Whether you should walk through it is a separate question, and it depends on numbers we cannot see from here.
What you have to check before filing:
- Every shareholder is eligible. Not just you. Adding one investor who is a nonresident alien later can end the election.
- No shareholder is a company. A partnership, an LLC or another corporation on the cap table disqualifies the election, whoever is behind it.
- You have 100 shareholders or fewer. Count family members as one where the rules allow it.
- You have one class of stock. If you already promised an investor a preference on profits or on a sale, you probably have two classes, and you are not eligible.
- You are inside the window. 2 months and 15 days from the start of the tax year, or any time in the year before.
If your business is an LLC rather than a corporation, there is an extra question to settle first: how the LLC is classified for federal tax. That is a separate topic, and it is covered on our entity classification and Form 8832 pages.
🌏 If it does not
If the IRS treats you as a nonresident alien, and you own shares, the company cannot be an S corporation. This is not a preference or a recommendation. It is a statutory bar in IRC § 1361(b)(1)(C).
Three things follow from that.
Filing Form 2553 does not help you. The other conditions do not matter. You could have one shareholder and one class of stock and file six months early, and the company still would not qualify, because you are the disqualifying shareholder.
Rev. Proc. 2013-30 does not help you either. Late election relief cures a missed deadline. It does not cure ineligibility.
Selling or parking the shares is not a shortcut. The condition applies to who actually holds the shares. If you want the S election, you have to stop being a shareholder, which usually defeats the reason you wanted the company in the first place.
What is left for you is the LLC route or the C corporation route. Those are the two tracks a nonresident founder actually chooses between, and they are separate pages in this guide.
One case worth knowing about, because people ask: if you later become a resident alien, by getting a green card or by passing the substantial presence test, the bar no longer applies to you. At that point the company can consider the election going forward. It does not fix any earlier year.
Where the two lanes split
| 🇺🇸 U.S. person | 🌏 Not a U.S. person | |
|---|---|---|
| Can you hold S corporation shares? | Yes | No. IRC § 1361(b)(1)(C) |
| Can the company file Form 2553? | Yes, if it passes the other tests | Not while you are a shareholder |
| The 100-shareholder cap | Applies to you | You are blocked before this is reached |
| The one-class-of-stock rule | Applies to you | You are blocked before this is reached |
| The 2-month-15-day deadline | Applies to you | Does not arise |
| Late relief under Rev. Proc. 2013-30 | Available for a missed deadline | Does not cure ineligibility |
| What the tax code decides it on | Tax residence, not passport | Tax residence, not passport |
The bottom row is the point. Both lanes are decided by the same test, and it is not nationality. A Korean citizen living in Austin who passes the substantial presence test sits in the left column. A U.S. citizen who has lived in Berlin for ten years also sits in the left column. A Korean citizen living in Seoul sits in the right column.
Common mistakes
🇺🇸 If the IRS counts you as a U.S. person
- Bringing in a foreign co-founder or angel investor without checking their tax residence first. One nonresident alien shareholder can end an existing S election.
- Promising an investor a preferred return on profits, then filing Form 2553. A preference on distributions is a second class of stock, and the company is not eligible.
- Missing the window by counting "two and a half months" loosely. The rule is 2 months and 15 days from the start of the tax year. For a calendar-year company that is 15 March, not 31 March.
🌏 If it does not
- Filing Form 2553 anyway because a blog post said S corporations pay less tax. The company is not eligible, and the filing does not become valid by being sent.
- Believing that having a U.S. LLC, a U.S. address and an EIN makes you a U.S. person. It does not. Company residence and personal tax residence are two different questions.
- Hoping that Rev. Proc. 2013-30 relief will fix the problem. It only forgives a late filing, not an ineligible shareholder.
FAQ
Can a nonresident alien own shares in an S corporation?
No. IRC § 1361(b)(1)(C) says a small business corporation cannot have a nonresident alien as a shareholder. The one exception is in IRC § 1361(c)(2)(B)(v): a nonresident alien who is a potential current beneficiary of an electing small business trust (ESBT) is not counted as a shareholder for this rule.
Is this about my citizenship?
No. It is about your tax residence. The IRS decides that with the green card test and the substantial presence test. A foreign citizen who passes either test is a resident alien and is allowed to hold S corporation shares. A foreign citizen who passes neither is a nonresident alien and is not.
When is Form 2553 due?
Either at any time during the tax year before the one you want the election to cover, or no more than 2 months and 15 days after the beginning of the tax year you want it to cover. For a company on a calendar tax year starting 1 January, that deadline is 15 March.
What happens if I file Form 2553 late?
Under Rev. Proc. 2013-30 the IRS can still grant the election for the year you wanted, if you show reasonable cause for the delay and show that the company reported consistently as an S corporation for the period. The Form 2553 instructions also require the late form to be filed within 3 years and 75 days of the effective date you are asking for. Relief is for lateness. It does not make an ineligible company eligible.
How many shareholders can an S corporation have?
100 or fewer. Spouses and members of the same family can be treated as one shareholder, so a family-owned company can have more individual owners than the raw number suggests.
Can I give my co-founder shares with no voting rights and still qualify?
Yes. The one-class-of-stock rule ignores differences in voting rights. What breaks the rule is a difference in the rights to profits or to money paid out when the company is wound up.
I became a U.S. resident this year. Can my company elect S status now?
The statutory bar applied to you while you were a nonresident alien. Once you are a resident alien, you are no longer a disqualifying shareholder, and the company can consider the election for a future tax year, if it meets the other conditions. It does not retroactively validate an earlier election.
I have a U.S. LLC, not a corporation. Does Form 2553 apply to me?
Not directly. The S election is made by a corporation. If your business is an LLC, you first have to settle how the LLC is classified for federal tax purposes, and that is a separate decision with its own form. See our entity classification and Form 8832 pages.
