Should Your Therapy Practice Elect S-Corp Status?

Someone in your practice-owners group swears the S-corp election saved them five figures. Someone else says their accountant told them not to bother. Both can be telling the truth, because the answer depends on two numbers that are different for every practice: your profit, and the salary you could defend paying yourself.

Let us take it apart properly.

How self-employment tax actually works

If your practice is a sole proprietorship or a single-member LLC, its profit lands on Schedule C and gets hit twice, once by income tax, and once by self-employment tax. SE tax is how the self-employed pay into Social Security and Medicare, and it is the piece the S-corp conversation is really about.

The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies to 92.35% of your net profit, not all of it. The Social Security portion stops at an annual wage base ($176,100 for 2025, indexed each year) while the Medicare portion has no ceiling, and an extra 0.9% Medicare surtax kicks in above $200,000 of earnings for a single filer or $250,000 for a married couple filing jointly. Half of the SE tax you pay comes back as an above-the-line deduction on your personal return.

Concretely, on $120,000 of practice profit: 92.35% of that is $110,820, and 15.3% of that is roughly $16,955 in self-employment tax, before a dollar of income tax.

That number is why people start asking about S-corps.

What the election changes, and what it does not

An S corporation is not a type of company you form. It is a tax election you make with the IRS on Form 2553, sitting on top of an entity that already exists, usually an LLC or PLLC, sometimes a corporation. (If that distinction is new, read LLC vs. S-Corp for Private Practice first; it is the confusion behind most bad entity decisions.)

Once the election is in place, the practice stops being an extension of you and starts behaving like an employer:

• You go on payroll and receive a W-2. Those wages carry FICA at the same 15.3%, half withheld from you, half paid by the company.
• Remaining profit passes through to you on a Schedule K-1 and is subject to income tax but not to SE tax or FICA.
• The practice files its own return, Form 1120-S, every year.

So the saving is not "paying less tax." It is narrower and more honest than that: the portion of profit you take as a distribution rather than as salary escapes the 15.3% payroll tax layer. Income tax is unchanged. Your legal liability protection is unchanged. Your malpractice exposure is unchanged.

Reasonable compensation is the whole ballgame

Here is the catch, and it is not a small one. The IRS requires an owner who works in an S corporation to take reasonable compensation for the services they perform, before taking distributions. Pay yourself a token salary and route everything else through distributions, and you are not doing tax planning. You are creating an adjustment waiting to happen.

This has been litigated. In a well-known case, a professional who paid himself a small salary while taking large distributions from his firm had a substantial portion of those distributions recharacterized as wages, with back payroll taxes, interest and penalties on top. The election was fine. The salary was not.

There is no formula in the code. The factors that decide it are things like your training and experience, the duties you actually perform, the hours you devote, what comparable practices pay for comparable work, what you pay non-owner staff, and how much of the profit is a return on your labor versus a return on the business itself.

The practical way to think about it: what would you have to pay someone else to do everything you do? A clinician carrying your caseload in your market, plus the owner work, hiring, supervising, marketing, contracting, running the business. Add those up and you are close to a defensible number.

That question also explains why group practices often get more benefit than solo ones. When a meaningful share of profit comes from clinicians other than you, that share is genuinely a return on the enterprise rather than payment for your personal services, and the case for distributions gets stronger.

An S-corp election does not lower your tax bill. A defensible salary paired with an S-corp election lowers your tax bill. Those are not the same sentence. The distinction most social-media advice skips

The costs on the other side of the ledger

Every article that quotes a savings number and stops there is selling you something. The election brings recurring obligations that cost real money and real attention:

• Payroll. A payroll provider, monthly, forever. Federal deposits on schedule, Form 941 quarterly, Form 940 annually, W-2 and W-3 at year end, plus state withholding and unemployment registration in each state where you pay wages.
• A second tax return. Form 1120-S is due March 15 for calendar-year filers, a month earlier than your personal return. Filing it late carries a penalty charged per shareholder, per month, a genuinely painful bill for a one-page mistake.
• Better bookkeeping. Distributions, payroll liabilities, owner equity and a balance sheet that ties out. The casual approach that survived Schedule C does not survive here.
• Adjacent obligations. Depending on your state: workers' compensation coverage, disability insurance, paid family leave contributions, several of which are triggered by having your first employee, which is now you.
• Professional fees. Your CPA is now preparing a corporate return, reviewing reasonable compensation and coordinating payroll. That costs more than a Schedule C.

Where the math starts to work

Strip it back to one line. Your approximate annual saving is:

(Profit − reasonable salary) × 15.3%, minus the added annual cost.

Continue the earlier example. Profit of $120,000, with a defensible salary of $80,000 for your role and market. Wages of $80,000 carry about $12,240 of FICA, against roughly $16,955 of SE tax as a sole proprietor, a payroll-tax difference of about $4,700 before you pay for payroll, the extra return and the bookkeeping. Real, but not life-changing, and you should net the costs out honestly before you celebrate.

Now shift one number. If your defensible salary were $110,000 instead, only $10,000 of profit sits outside the payroll-tax layer and the whole exercise stops making sense. If profit were $220,000 against that same $80,000 salary, the picture changes dramatically in the other direction.

Which is why the useful question is never "how much do I have to make?" It is "how much profit sits above the salary I could defend?" As a rough orientation, the conversation rarely earns its keep below roughly $60,000–$80,000 of profit, usually starts to be worth modeling somewhere north of that, and becomes hard to ignore once the gap between profit and a defensible salary runs into six figures. Those are orientation points, not thresholds, your state, your filing status and your salary benchmark move them.

One more effect at the top end: once your W-2 wages pass the Social Security wage base, additional distributions only avoid the Medicare portion, so each extra dollar saves far less than 15.3 cents.

The QBI wrinkle nobody mentions

The qualified business income deduction lets many owners deduct up to 20% of business income. Mental health services are treated as a "specified service trade or business," which means the deduction phases out once taxable income passes a threshold, $197,300 for a single filer and $394,600 for a married couple filing jointly for 2025, phasing out over the following $50,000 and $100,000 respectively. Those figures are indexed and were adjusted by 2025 legislation, so confirm the current-year numbers rather than relying on any article, including this one.

The interaction matters: W-2 wages you pay yourself are not qualified business income. Raising your salary shrinks the QBI deduction at the same time it raises payroll tax, which trims the net benefit of the election for owners still inside the phase-out range. Above the range, QBI may be gone entirely and the calculation simplifies again. Any S-corp analysis worth paying for models this rather than ignoring it.

State-level gotchas

Federal savings can be quietly eaten at the state or city level. A few real examples:

• New York City does not recognize S-corp status. An S corporation doing business in the city pays the city's general corporation tax at the entity level, which can wipe out much of the federal benefit for a Manhattan or Brooklyn practice.
• New York State requires its own S election, Form CT-6, in addition to the federal one, and imposes a fixed dollar minimum tax.
• California charges a 1.5% franchise tax on S-corp net income, with an $800 annual minimum, and does not permit LLCs for most licensed professional services at all.
• Illinois applies a personal property replacement tax to S corporations.
• Many states now offer a pass-through entity tax election that can be worth more than the S-corp savings themselves. Ask about it specifically.

If you are licensed in more than one state or see telehealth clients across state lines, add payroll registration and apportionment to the list of things to check before you elect.

Timing and deadlines

Form 2553 must generally be filed no later than two months and fifteen days after the beginning of the tax year the election is to take effect, March 15 for a calendar-year practice, or at any point during the preceding year. A brand-new entity can elect from its first day.

Miss the window and you are not necessarily out of luck: the IRS has a late-election relief procedure available for roughly three years and 75 days after the intended effective date, provided you had reasonable cause and have otherwise behaved consistently with the election. It is a real path, but it is paperwork you would rather not need.

Also worth knowing: once you revoke an S election, there is generally a five-year wait before you can elect again without IRS consent. This is not a switch to flip back and forth while you experiment.

Who cannot elect

The eligibility rules are narrow but firm. The entity must be domestic, have no more than 100 shareholders, have only one class of stock, and have only eligible shareholders, individuals, certain trusts and estates. A nonresident alien cannot be a shareholder, which rules the election out for some practice owners entirely. On top of that, most states restrict ownership of a professional entity to individuals holding the relevant clinical license.

Because of that shareholder rule, our own S-corp services require that shareholders meet federal S corporation eligibility requirements, including not being treated as nonresident aliens for federal tax purposes.

How to decide

Three steps, in this order:

1. Get your books current. You cannot model an election on a profit figure you are guessing at. If the books are behind, that is the first job.
2. Benchmark your salary before you model the savings. Everything downstream depends on it, and it is the number the IRS looks at first.
3. Run the full picture (federal, state, city, QBI, payroll cost, compliance cost) and compare it to doing nothing. If the answer is close, doing nothing is often the better answer, because "close" does not pay for the ongoing administration.
