Can a Close Corporation Be an S-Corp: Rules, Election, and Compliance

Yes, a close corporation can be an S-corp. The two designations sit on different legal layers and don’t conflict: a close corporation is a state-law governance structure for small, tightly held businesses, while S-corp status is a federal tax election made with the IRS. If your close corporation meets the eligibility rules in Subchapter S of the Internal Revenue Code, it can hold both at once and often should.

Why the Two Designations Coexist

A close corporation is formed under a specific state statute built for small ownership groups. It lets owners skip formalities that larger corporations face, such as mandatory annual meetings or a formal board, while keeping limited liability. Day-to-day governance ends up looking more like a partnership.

S-corp status is about taxes, nothing else. It’s a federal election under Subchapter S that turns a corporation from a double-taxed C-corp into a pass-through entity. Each shareholder reports their share of the company’s income on their personal return, and the corporation itself generally pays no federal income tax.¹

Because your state statute answers a governance question and Subchapter S answers a tax question, satisfying both at the same time is normal. The small, defined ownership group that a close corporation already has fits the S-corp shareholder restrictions without much stretching.

Why Close Corporations Elect S-Corp Status

The main draw is payroll tax savings. Under a C-corp, all compensation to shareholder-employees carries Social Security tax (6.2% each for employer and employee) and Medicare tax (1.45% each). With an S-corp election, shareholder-employees can split their pay between a reasonable salary and distributions. Only the salary portion is subject to payroll taxes. Distributions pass through as ordinary income but skip the payroll tax hit.

The IRS watches this closely. If shareholder-employees pay themselves an unreasonably low salary and take most of their money as distributions, the IRS can reclassify the distributions as wages and assess back payroll taxes, penalties, and interest. Courts have consistently sided with the IRS on this, including cases where shareholders paid themselves nothing in wages.²

Federal Eligibility Requirements

Not every close corporation qualifies. The rules in IRC §1361 are strict, and violating any one of them disqualifies the corporation entirely.

No more than 100 shareholders. Members of a single family and their estates count as one shareholder.³
Every shareholder must be a U.S. citizen or resident individual, certain estates, or certain qualifying trusts. Partnerships, other corporations, and nonresident aliens cannot own shares.³
Only one class of stock. Shares can carry different voting rights, but every share must have identical rights to distributions and liquidation proceeds.³
The corporation must be organized in the United States.

The one-class-of-stock rule is where close corporations most often get tripped up. Close corporation shareholder agreements frequently include buy-sell formulas, redemption at book value, or tiered profit-sharing arrangements. If those provisions give some shares larger or different economic rights than others, the IRS may treat the corporation as having two classes of stock, which kills the S-corp election. Voting differences are safe. Economic differences are not.³ Before you file, have someone read your shareholder agreement with this rule in mind.

Which Trusts Can Hold Shares

Close corporations often use trusts for estate planning, and only specific trust types qualify as S-corp shareholders. The permitted categories under IRC §1361(c)(2) are grantor trusts, testamentary trusts that receive shares from an estate (eligible for two years after the transfer), voting trusts, Qualified Subchapter S Trusts (QSSTs), and Electing Small Business Trusts (ESBTs).³

A QSST must have a single income beneficiary, distribute all income to that beneficiary each year, and cannot distribute principal to anyone else during the beneficiary’s lifetime. An ESBT can have multiple beneficiaries, but the trust’s S-corp income is taxed at the highest individual rate. Transferring shares into a family trust that doesn’t fit one of these categories terminates the entire corporation’s S-corp status.

How to Make the Election

The election is filed on IRS Form 2553, “Election by a Small Business Corporation.” The form asks for the corporation’s legal name, EIN, date of incorporation, state of organization, and each shareholder’s name, address, Social Security number, share count, and acquisition date. Most small businesses choose a calendar tax year ending December 31.⁴

Every shareholder must sign the consent section. In community property states, a shareholder’s spouse must sign too, even if they aren’t listed as a direct owner, because community property law gives them a legal interest in the shares.⁴ One missing signature invalidates the election.

Deadlines

To have the election take effect for the current tax year, file no later than two months and 15 days after the start of that tax year. For a calendar-year corporation, that means March 15. You can also file at any point during the preceding tax year. Expect a written acceptance or denial from the IRS in roughly 60 days.⁴

Late Filing Relief

A missed deadline isn’t necessarily fatal. Revenue Procedure 2013-30 provides a simplified path for late elections without a private letter ruling. The corporation must have intended to be an S-corp as of the desired effective date, must have had reasonable cause for the late filing, and must request relief within three years and 75 days of that effective date. There’s a broader exception when the corporation and all shareholders have already been filing consistent with S-corp status.⁵

Ongoing Compliance

Once the election is in place, the corporation files Form 1120-S annually. For calendar-year corporations, the deadline is March 15. Form 7004 buys an automatic six-month extension.⁶ The corporation issues a Schedule K-1 to each shareholder reporting their share of income, deductions, and credits, and files copies with the IRS.⁷

Any shareholder who works in the business must be paid reasonable compensation as a W-2 employee before taking distributions. Reasonable means what the shareholder-employee would earn for similar work at a comparable business.² The corporation runs payroll taxes on that salary like any other employer.⁸

Watch for Built-In Gains When Converting From C-Corp

If your close corporation has been running as a C-corp and you elect S-corp status, any appreciation in the corporation’s assets on the date of conversion (the “built-in gain”) stays subject to corporate-level tax if those assets are sold during a five-year recognition period after the election takes effect. The tax hits at the highest corporate rate on the net recognized built-in gain for the year.⁹

The built-in gain is measured as the difference between the fair market value of the corporation’s assets on the first day of the election and their adjusted tax basis at that time.⁹ For close corporations holding appreciated real estate, valuable equipment, or significant inventory, timing the election is a strategic call, not a paperwork exercise.

How S-Corp Status Can Be Lost

The status terminates automatically if the corporation stops meeting any eligibility requirement. Common triggers: a share transfer brings in an ineligible shareholder, the shareholder count exceeds 100, or a shareholder agreement creates a second class of stock. For close corporations, the risk tends to show up when an owner dies and shares pass to an ineligible trust, or a divorce settlement moves shares to someone who doesn’t qualify.

The IRS can grant relief for inadvertent terminations under §1362(f) if the corporation shows the disqualifying event was unintentional, corrects it within a reasonable time, and all affected shareholders agree to any adjustments the IRS requires.¹⁰ Relief isn’t automatic; the corporation bears the burden of showing the mistake was inadvertent. If the termination sticks, the corporation can’t re-elect S-corp status for five taxable years unless the IRS consents to an earlier re-election.¹¹

Shareholders can also end the election voluntarily by revocation. Unlike the original election, revocation only needs shareholders holding more than half of the shares. A revocation filed on or before March 15 of a calendar year is retroactive to January 1 of that year; after March 15, it takes effect January 1 of the following year. The revocation can also name a future effective date.¹⁰

State Treatment Is Separate

A federal S-corp election doesn’t automatically mean your state treats you the same way. Many states accept the federal election without additional paperwork, some require a separate state-level election, and a few impose their own entity-level tax on S-corporations regardless of federal pass-through treatment. Check with your state’s department of revenue after you file federally.

The state close corporation designation and the federal S-corp election also live on parallel tracks. Losing close corporation status under state law doesn’t touch your federal election, and losing S-corp status with the IRS doesn’t change your state-law corporate structure. Each has to be maintained on its own.
