One class of stock: why S-corp owners cannot take unequal distributions

Can S-corp owners take different distribution percentages based on production?

No. An S corporation may have only one class of stock, and it has only one class when all outstanding shares confer identical rights to distribution and liquidation proceeds 1Ref 1Internal Revenue Service (2020).Instructions for Form 2553 (12/2020), Election by a Small Business Corporation.The one class of stock test itself: a corporation has only one class of stock only if all outstanding shares confer identical rights to distribution and liquidation proceeds, and differences in voting rights are disregarded.. Two owners holding half the shares each hold the right to half of any distribution, whatever either of them produced that year. A split paying 60 percent of the profit to one of them attaches a different right to the same stock.

The rule is federal, and it sits on the short list of conditions a corporation meets to elect and keep S status 2Ref 2Internal Revenue Service (2026).S corporations.That having only one class of stock is a federal eligibility condition for electing and keeping S status, and that S corporation income passes through to shareholders.. The test sets aside differences in voting rights 1Ref 1Internal Revenue Service (2020).Instructions for Form 2553 (12/2020), Election by a Small Business Corporation.The one class of stock test itself: a corporation has only one class of stock only if all outstanding shares confer identical rights to distribution and liquidation proceeds, and differences in voting rights are disregarded.. A junior owner can hold non-voting shares and still hold the same per-share claim on every dollar distributed as the owner who votes.

The plain-language version above comes from the Form 2553 instructions. The regulation underneath it is 26 CFR §1.1361-1, whose paragraph (l) carries the one-class-of-stock test along with the analysis of when a binding agreement about distributions counts as a second class 3Ref 3Internal Revenue Service / U.S. Department of the Treasury (2026).26 CFR §1.1361-1 — S corporation defined (paragraph (l), one class of stock).Named by section number only, as the regulation carrying the one-class-of-stock test and the governing-provisions analysis a CPA reads a profit-split clause against. No text of the regulation is stated in the article.. Name that paragraph when you call your CPA. It is the text they will open.

State law does not move any of this. What varies by state is which entity a licensed practice may form at all, so read your own state's professional-entity statute before assuming an LLC is open to a clinical practice there, and read it again for every state you hold a license in.

What an uneven distribution puts at risk

The election itself. A corporation that stops meeting the small-business-corporation definition loses its S election automatically, effective the day it stopped meeting it 4Ref 4Internal Revenue Service (2025).Instructions for Form 1120-S (2025), U.S. Income Tax Return for an S Corporation.That the S election terminates automatically, effective the day the corporation stops meeting the small-business-corporation definition, and that a corporation believing the termination was inadvertent can request IRS permission to continue S treatment under Reg. §1.1362-4., and having only one class of stock is part of that definition 2Ref 2Internal Revenue Service (2026).S corporations.That having only one class of stock is a federal eligibility condition for electing and keeping S status, and that S corporation income passes through to shareholders.. The filing date does not move that effective date, and neither does the date somebody notices. From that day forward the corporation sits outside S treatment.

A terminated election is not always the end of it. A corporation that believes the termination was inadvertent can ask the IRS for permission to continue being treated as an S corporation, subject to the requirements of Reg. §1.1362-4 4Ref 4Internal Revenue Service (2025).Instructions for Form 1120-S (2025), U.S. Income Tax Return for an S Corporation.That the S election terminates automatically, effective the day the corporation stops meeting the small-business-corporation definition, and that a corporation believing the termination was inadvertent can request IRS permission to continue S treatment under Reg. §1.1362-4.. The instructions describe the request. They do not report how often it is granted, what it costs, or how long it takes, and no source cited on this page fills that in.

The books record it either way. An uneven distribution sits in the corporation's own ledger and on its own return, so a group that has paid one owner more than their shares carry has a documented year to explain, and a decision to make about how the next one gets paid.

Groups that want to pay for production answer that on the payroll side.

Compensation is where production gets paid

Through W-2 wages, before any distribution. An S corporation pays a shareholder-employee reasonable compensation for the services that employee provides before it makes any non-wage distribution to them, and the IRS has the authority to reclassify distributions as wages where that order is not kept 5Ref 5Internal Revenue Service (2026).S Corporation Compensation and Medical Insurance Issues.That an S corporation pays a shareholder-employee reasonable compensation for services before any non-wage distribution, and that the IRS has the authority to reclassify distributions as wages where that ordering is not followed.. Two owners with identical shares can end a year with different total pay, because the salary is for the work and the distribution is for the shares.

What counts as reasonable for a given clinician is its own determination. The mechanics of paying yourself out of an S corporation, and how S-corp reasonable compensation gets set and documented, are their own analysis; this page assumes that line is already defensible before the distribution line is reached.

How a group sets those salaries is convention rather than federal rule. Many practices agree a base for each owner-clinician, revisit it on a schedule fixed in advance, and keep minutes recording why a number moved. Nothing in the S corporation rules cited here prescribes a formula for it, which is why the compensation schedule is worth drafting before a second owner signs anything.

This becomes a live question the day clinician #2 signs as an owner. With one owner, production and pay are the same conversation; with two, the salary line and the distribution line have to be set separately.

The other entity allocates by agreement

An LLC taxed as a partnership can do what an S corporation cannot. A partnership's allocation of income, gain, loss, deduction or credit among its partners is fixed by the partnership agreement, meaning the original agreement plus any modifications the partners adopt 6Ref 6Internal Revenue Service (2025).Publication 541 (12/2025), Partnerships.That a partnership's or partnership-taxed LLC's allocation of income, gain, loss, deduction or credit is fixed by the partnership agreement (original plus adopted modifications), and that local law is treated as part of the agreement wherever it is silent.. A production-weighted split is a term of that agreement, which is why groups that want the split to land at the profit line look at this form first.

But the agreement is not the last word on it. How far a special allocation may depart from ownership percentage is bounded by the substantial-economic-effect rules at 26 CFR §1.704-1(b)(2) 7Ref 7Internal Revenue Service / U.S. Department of the Treasury (2026).26 CFR §1.704-1 — Partner's distributive share (paragraph (b)(2), substantial economic effect).Named by section number only, as the substantial-economic-effect rules that bound how far a partnership or LLC special allocation may depart from ownership percentage. No text of the test is stated in the article.. That test lives in the regulation and it belongs to whoever drafts the document. What it means for a two-owner practice is that a production split is a piece of tax structuring with its own rules, priced accordingly by the lawyer who writes it and the CPA who signs off on it.

Where the agreement says nothing, state law says it instead: an item the agreement is silent on is allocated under local law, which is then treated as part of the agreement 6Ref 6Internal Revenue Service (2025).Publication 541 (12/2025), Partnerships.That a partnership's or partnership-taxed LLC's allocation of income, gain, loss, deduction or credit is fixed by the partnership agreement (original plus adopted modifications), and that local law is treated as part of the agreement wherever it is silent.. Two clinicians who never wrote the split down have still agreed to one. Which default applies, and what it says, is a question about their state.

None of this reopens the entity decision on its own. The s-corp math that made the election worth filing for one owner does not automatically survive a second owner who expects to be paid on production, and whether production can be measured per clinician at all depends on how the practice collects, which sits downstream of the insurance question. Run the two together.

Writing the split so it survives the next owner

Keep the ownership percentages and the compensation schedule in two separate documents. In an S corporation the first does all of the distribution work and cannot be conditioned on production; the second is where production appears. A group that blends both into a single profit-split clause has written the sentence a CPA has to read against 26 CFR §1.1361-1(l) 3Ref 3Internal Revenue Service / U.S. Department of the Treasury (2026).26 CFR §1.1361-1 — S corporation defined (paragraph (l), one class of stock).Named by section number only, as the regulation carrying the one-class-of-stock test and the governing-provisions analysis a CPA reads a profit-split clause against. No text of the regulation is stated in the article. before the next distribution leaves the account.

Counsel earns the fee at four specific moments, and a solo owner adding a partner hits at least two of them in the first year:

• A new owner buys in, or an existing owner is bought out, on terms the stock does not already describe
• Any document promises one owner a payment measured by that owner's own collections, paid out of corporate profit
• A distribution has already gone out uneven, and the CPA has to say whether the election survived it or whether the next step is a relief request under Reg. §1.1362-4 4Ref 4Internal Revenue Service (2025).Instructions for Form 1120-S (2025), U.S. Income Tax Return for an S Corporation.That the S election terminates automatically, effective the day the corporation stops meeting the small-business-corporation definition, and that a corporation believing the termination was inadvertent can request IRS permission to continue S treatment under Reg. §1.1362-4.
• A second state, a second entity, or a management company sits between the practice and its owners

Minutes carry more weight here than they did in a solo year. A distribution approved by owners who recorded the percentages they were approving reads differently, two years later, from a transfer somebody made at the end of a quarter.

What to bring to the CPA before the next distribution

Four documents and one number. Bring the Form 2553 election as filed, the current shareholder register with each owner's percentage, the payroll records showing each owner-clinician's wages year to date, and the distributions taken year to date by owner. The number is the percentage each owner has received, set against the percentage their shares carry. Where those two diverge, the appointment starts there.

S corporation income passes through to the shareholders 2Ref 2Internal Revenue Service (2026).S corporations.That having only one class of stock is a federal eligibility condition for electing and keeping S status, and that S corporation income passes through to shareholders., so an owner can owe tax on profit that never left the practice's account. That is one more reason to check the distribution percentages against the register before year end.

If a distribution has already gone out uneven, open with that. Whether the election survived is the CPA's first call. The relief route under Reg. §1.1362-4 exists for a termination the corporation believes was inadvertent 4Ref 4Internal Revenue Service (2025).Instructions for Form 1120-S (2025), U.S. Income Tax Return for an S Corporation.That the S election terminates automatically, effective the day the corporation stops meeting the small-business-corporation definition, and that a corporation believing the termination was inadvertent can request IRS permission to continue S treatment under Reg. §1.1362-4., and requesting it is a filing decision to make together. Everything else on the list can wait a week.
