S-Corp for Physicians: Is It Right for You?
A physician earning $400,000 through a single member LLC pays roughly $35,000 in self employment tax before a single dollar goes to income tax. That number catches most 1099 physicians off guard the first time they see it on a return.
The S-Corp election is the most common tool physicians use to reduce that self employment tax hit, and for good reason. When the setup holds together, it can lower what you owe in employment taxes each year. But the setup is doing a lot of heavy lifting in that sentence. Get the salary wrong, pick the wrong state, or miss a filing deadline, and the benefit can disappear, sometimes with penalties on top.
This post covers the full S-Corp decision for physicians: how the election actually works, when it pencils out, how to set reasonable compensation by specialty, the state level traps that are easy to miss, and what to do if you missed the deadline or need to unwind the election entirely. Whether you are a solo 1099 physician weighing the LLC-to-S-Corp move or a group practice evaluating entity options, these are the pieces your tax team should be walking through with you.

What Is an S-Corp (and What Is It Not)?
An S-Corp Is a Tax Election, Not an Entity Type
This is the single most misunderstood point in physician tax planning. An S-Corp is not a type of business entity. You cannot "form" an S-Corp at the Secretary of State's office. You form an LLC or a corporation at the state level, and then you ask the IRS to tax that entity as an S-Corp by filing Form 2553.
That distinction matters because:
Your state sees an LLC (or corporation). The IRS sees an S-Corp. These are two different conversations.
Your liability protection comes from the LLC or corporation formation, not from the S-Corp election.
If the IRS ever revokes or rejects your S-Corp election, you still have a functioning LLC or corporation. You just lose the tax treatment.
Think of it this way: the LLC is the house. The S-Corp election is the tax paint job on the house. You can repaint. You cannot unpaint.
How Does the LLC Plus S-Corp Election Work for Physicians?
The most common path for a solo 1099 physician looks like this:
Form a single member LLC (or PLLC, depending on your state) with the Secretary of State.
Get an EIN from the IRS.
File Form 2553 with the IRS to elect S-Corp tax treatment.
Set up payroll, because you are now both the employer and the employee.
Pay yourself a reasonable salary via W-2 payroll.
Take remaining profits as shareholder distributions.
The salary portion gets hit with FICA taxes (Social Security plus Medicare). The distribution portion does not. That split is where the benefit comes from.
For physician groups, the mechanics are similar but the entity structure often starts as a multi-member LLC or professional corporation. The S-Corp election still applies, but the reasonable compensation analysis and QBI math get more complex.
How Does the S-Corp Election Lower Self Employment Tax?
Why Does Self Employment Tax Hit 1099 Physicians So Hard?
If you are a 1099 physician operating as a sole proprietor or a single member LLC (taxed as a disregarded entity), every dollar of net profit is subject to self employment tax. The IRS applies a 92.35% factor to your net earnings before calculating SE tax (this accounts for the employer-equivalent portion of the deduction). From there, the rates are 15.3% on the first $184,500 (2026 Social Security wage base) and 2.9% on everything above it, plus the 0.9% Additional Medicare Tax on earnings over $200,000 ($250,000 if married filing jointly).
For a physician netting $400,000, the self employment tax bill looks roughly like this:
SE tax base ($400,000 x 92.35%): $369,400
Social Security portion (12.4% on $184,500): $22,878
Medicare portion (2.9% on $369,400): $10,713
Additional Medicare Tax (0.9% on $169,400 above $200K threshold): $1,525
Total self employment tax: approximately $35,116
You get to deduct half of that (about $17,558) on your 1040, but the cash still leaves your account.
How Does Splitting Salary and Distributions Lower the Bill?
With an S-Corp election, you split that $400,000 into two parts:
Salary (subject to FICA): You pay yourself a reasonable salary, say $250,000 for an emergency medicine physician.
Distributions (not subject to FICA): The remaining $150,000 comes out as a shareholder distribution, free of self employment tax.
The distribution amount is still subject to income tax. It is not a free ride. But it skips the 15.3%/2.9%/0.9% layer entirely.
What Does the Math Look Like at $400K Net Income?
Take Dr. Patel's numbers. Dr. Patel is an emergency medicine physician earning $400,000 net through her solo PLLC, currently taxed as a disregarded entity.
Without an S-Corp election:
Net income subject to SE tax: $400,000
SE tax base (92.35%): $369,400
Self employment tax: approximately $35,116
Deductible half of SE tax: $17,558
With an S-Corp election (reasonable salary of $250,000):
W-2 salary subject to FICA: $250,000
Employer FICA (6.2% SS up to the wage base plus 1.45% Medicare): approximately $15,064
Employee FICA (same): approximately $15,064
Additional Medicare Tax (0.9% on salary over $200,000): $450
Distribution not subject to FICA: $150,000
Total employment taxes: approximately $30,578
The difference between those two totals is what the election is doing at this salary level, and at $250,000 on $400,000 of income that gap is modest, because more than half the income still runs through payroll. The election does more work as the salary to distribution ratio tilts toward distributions. If Dr. Patel's specialty benchmarks support a $200,000 reasonable salary, total FICA on that salary runs closer to $28,678, and the gap against the no election figure widens. The point is not a fixed number. The benefit scales with the spread between net income and a defensible salary, which is why the break even analysis matters before you elect.
To see the contrast, consider Dr. Nguyen, an orthopedic surgeon netting $600,000 through his solo PLLC. MGMA data puts the median orthopedic surgery compensation around $640,000, so his net income is actually below the specialty median. His tax team sets a reasonable salary of $300,000 based on his hours, experience, and geography.
Without an S-Corp election:
Net income subject to SE tax: $600,000
SE tax base (92.35%): $554,100
Self-employment tax: approximately $42,134
Deductible half of SE tax: $21,067
With an S-Corp election (reasonable salary of $300,000):
Total FICA on $300,000 salary: approximately $32,478
Distribution not subject to FICA: $300,000
On paper the gap between those two employment tax figures looks meaningful, but $6,000 to $10,000 in annual compliance costs absorb a large share of it in year one, so the margin can be tight. Two things still make the S-Corp worth evaluating at this income level. First, the compliance costs are largely fixed (payroll, bookkeeping, and the 1120-S filing cost roughly the same at $300K income or $600K income), so the ratio improves as income grows or costs come down. Second, most orthopedic surgeons earning $600,000 have other planning reasons to run an S-Corp (retirement plan contributions through payroll, cleaner entity structure for future partners, and the PTET election that layers on top). The S-Corp decision at this level is not about employment tax math alone.
At $150,000 net income, the math almost never works. The income level where the election starts to pencil depends on your specialty, your state, and your compliance costs.
What Counts as Reasonable Compensation?
What Does "Reasonable" Mean for Your Specialty?
The IRS requires that S-Corp owner employees pay themselves a "reasonable" salary for the services they perform. There is no fixed formula. Reasonable compensation is determined by what the open market would pay someone with your training, experience, and specialty to do the same work.
For physicians, this is not a vague hypothetical. Physician compensation data is published annually by multiple sources, and the IRS knows it exists.
Factors the IRS considers include:
Your medical specialty
Years of experience and board certification status
Geographic region
Hours worked
Whether you perform administrative duties in addition to clinical work
Comparable compensation at similar practices
The IRS will compare your W-2 salary against published benchmarks. A large gap between your salary and the benchmark is what draws IRS attention.
How Do MGMA Benchmarks Set the Floor?
The Medical Group Management Association (MGMA) publishes the most widely referenced physician compensation survey in the country. The IRS is familiar with it. Your tax team should be using it.
A simplified look at approximate median total compensation by specialty (these figures shift annually, so always reference the current year's survey):
Specialty | Approximate median total compensation |
Family Medicine | $275,000 to $300,000 |
Internal Medicine | $290,000 to $310,000 |
Emergency Medicine | $350,000 to $380,000 |
Anesthesiology | $420,000 to $450,000 |
Orthopedic Surgery | $550,000 to $620,000 |
Dermatology | $450,000 to $500,000 |
Cardiology (Invasive) | $600,000 to $700,000 |
These are total compensation figures, not recommended S-Corp salaries. Your reasonable salary does not necessarily need to match the median, especially if you work part time, have fewer years of experience, or your practice revenue is below the specialty benchmark. But it does need to be defensible relative to these data points.
A common rule of thumb is setting salary at 60% of net income for physician S-Corps, but rules of thumb are not IRS guidance. The actual reasonable salary depends on your specific facts and circumstances. If your net income is $400,000 and the specialty median is $350,000, setting your salary at $150,000 is hard to defend if the IRS looks closely. We break the benchmarks down specialty by specialty in Reasonable Salary by Specialty for Physician S-Corps.
What Happens If You Set Your Salary Too Low?
The IRS can reclassify S-Corp distributions as wages, retroactively. When that happens:
Back FICA taxes are assessed on the reclassified amount (both the employer and employee share)
Penalties for failure to deposit payroll taxes apply
Interest accrues from the original due dates
Your S-Corp's tax returns may be reopened for multiple years
The Watson v. Commissioner case is the textbook example. An accountant paid himself $24,000 in salary on $200,000+ of S-Corp profits. The Tax Court found the salary unreasonably low and reclassified distributions as wages. The penalties and back taxes wiped out any benefit from the low salary.
Physicians are even more exposed than the accountant in Watson, because physician compensation benchmarks are published, specific, and widely known.
The bottom line: the S-Corp election is not a license to set your salary at $50,000 and call the rest distributions. It is a tool that works when reasonable compensation is set honestly.
S-Corp vs LLC vs Partnership: Which Structure Fits?
Solo 1099 Physician (LLC Taxed as S-Corp)
For a solo 1099 physician, the most common and straightforward structure is a single member LLC (or PLLC) that elects S-Corp taxation. This gives you:
Liability protection from the LLC
Pass through taxation (no entity-level federal income tax)
The salary/distribution split for FICA purposes
Simplicity: one owner, one entity, one payroll
The trade off is cost. You now need:
A separate payroll system (Gusto, Rippling, ADP, or similar)
Quarterly payroll tax deposits
A separate S-Corp tax return (Form 1120-S) filed annually
Potentially higher bookkeeping costs
If your net income is below $80,000 to $100,000, the payroll and filing costs may eat the FICA benefit entirely. More on break even thresholds below.
Physician Groups and Multi-Member Entities
When two or more physicians practice together, entity selection gets more layered. The common options are:
Multi-member LLC taxed as a partnership (default)
Multi-member LLC taxed as an S-Corp (elected)
Professional Corporation (PC) taxed as an S-Corp
Each has different implications for self-employment tax, QBI deductions, ownership transfer, and state level taxation. The partnership default avoids SE tax on distributive shares for limited partners but subjects guaranteed payments to SE tax. The S-Corp avoids SE tax on distributions but requires reasonable salaries for all physician owners.
The right answer depends on the number of owners, income levels, state of formation, and whether any owners are non-physician investors. The side by side comparison, including the QBI maximization math, lives in S-Corp vs Partnership for Physician Groups.
When Does a C-Corp or Partnership Make More Sense?
In a few specific scenarios, the S-Corp election is not the best choice:
If the practice plans to offer equity to non-physician employees or outside investors, the S-Corp's single class of stock requirement can be a dealbreaker
If the practice has significant fringe benefit needs (health insurance, disability, etc.), C-Corp taxation may be more favorable for the deductibility of those benefits
If the physicians want maximum flexibility in allocating income and losses among partners, a partnership offers special allocation capabilities that an S-Corp cannot match
If the physician group is structured as a multi-specialty group with widely varying compensation, partnership allocations may be simpler than the S-Corp reasonable salary per-owner analysis
How Does the S-Corp Election Affect Your QBI Deduction?
Section 199A Basics for Physicians
The Section 199A qualified business income (QBI) deduction allows eligible pass through business owners to deduct up to 20% of qualified business income. For a physician earning $400,000 in QBI, that is potentially an $80,000 deduction, reducing taxable income significantly. The 2025 tax law (the One Big Beautiful Bill Act) made this deduction permanent, so it is no longer scheduled to sunset.
But physicians hit a wall. Most medical practices are classified as Specified Service Trades or Businesses (SSTBs) under Section 199A. SSTBs include health, law, accounting, consulting, and several other fields.
For SSTBs, the deduction is fully available below the taxable income threshold, then phases out across a defined range. For 2026 the figures are approximately:
Filing status | Full QBI deduction up to | Fully phased out by |
Single | about $201,750 | about $276,750 |
Married filing jointly | about $403,500 | about $553,500 |
The 2025 law widened that phase out range (to $75,000 for single filers and $150,000 for joint filers), so some physicians who were fully phased out under the old, lower thresholds now keep a partial deduction. The same law added a minimum deduction of $400 for taxpayers with at least $1,000 of QBI who materially participate, though that floor does not rescue an SSTB owner whose income sits above the top of the range. Many attending physicians still land above the SSTB ceiling, where the QBI deduction is zero regardless of entity structure.
When Does Your S-Corp Salary Reduce Your QBI Benefit?
This is where the S-Corp election creates a tension worth understanding. QBI is calculated after subtracting reasonable compensation. In an S-Corp, the W-2 salary you pay yourself reduces the amount of QBI available for the 199A deduction.
Example:
Net Profit | $400,000 |
Reasonable Salary | $250,000 |
QBI | $150,000 |
The potential 199A deduction on that QBI = $30,000. But if you are over the SSTB threshold, the deduction is zero anyway.
For physicians in the phase out range (taxable income roughly between $201,750 and $276,750 for single filers, or between $403,500 and $553,500 for MFJ), the interplay between S-Corp salary and the QBI deduction requires precise modeling. A slightly lower salary might preserve a few thousand dollars in QBI deduction while a slightly higher salary might reduce FICA exposure that exceeds the QBI loss.
The math here is not intuitive and the optimal salary is rarely a round number, so it is worth modeling carefully rather than eyeballing a figure.
For physicians well above the SSTB phase out, the QBI deduction is already zero. The S-Corp salary decision can focus purely on FICA exposure vs. IRS reasonableness risk.
State Level Traps: California, New York, New Jersey, and PTET
California's $800 Minimum Franchise Tax (and the 1.5% Net Income Tax)
California is the state that surprises the most physicians considering an S-Corp election. Every LLC and every S-Corp registered in California owes a minimum $800 franchise tax per year, regardless of income.
On top of that, California imposes a 1.5% tax on S-Corp net income (with a minimum of $800). This is an entity level tax, not a pass through tax. It comes off the top before you see distributions.
For a California physician with $400,000 in S-Corp net income:
Franchise tax: $6,000 (1.5% of $400,000)
This reduces the net benefit from the S-Corp election
The franchise tax does not kill the S-Corp election for most California physicians, but it narrows the margin. A physician netting $150,000 in California may find that the franchise tax plus compliance costs eat most of the benefit.
California also does not conform to certain federal S-Corp provisions, which creates additional filing complexity. Make sure your tax team is experienced with California S-Corp returns (Form 100S) specifically.
New York and New Jersey S-Corp Considerations
New York imposes a fixed dollar minimum tax on S-Corps based on New York receipts:
$25 for receipts up to $100,000
Up to $4,500 for receipts over $25 million
For most solo physician S-Corps in New York, this is a minor cost. But New York City adds its own layer: NYC does not recognize the S-Corp election at all. S-Corps operating in NYC are subject to the city's General Corporation Tax (GCT) or Business Corporation Tax, treating the entity as a C-Corp for city tax purposes. This can be a significant unexpected hit.
New Jersey imposes a minimum corporate business tax on S-Corps and has additional considerations around the pass through business alternative income tax (BAIT). New Jersey BAIT can actually benefit physician S-Corps by allowing an entity level deduction that bypasses the federal SALT cap, but the election and payment deadlines are strict.
If you practice in New York, New Jersey, or California, the S-Corp decision is not a simple yes/no. It requires state specific modeling, which we lay out state by state in S-Corp State Taxes: CA Franchise Tax and NY/NJ Surcharges.
Pass Through Entity Tax Elections by State
The pass through entity tax (PTET) is a workaround for the federal SALT cap. The 2025 tax law raised that cap to $40,400 for 2026 (up from $10,000), but it phases down toward a $10,000 floor once household income climbs above about $505,000, so it still bites for most high-income physicians. Over 30 states now offer some form of PTET election, allowing the S-Corp itself to pay state income tax at the entity level, generating a federal deduction that is not subject to the SALT cap. The 2025 law left the PTET workaround intact.
For physician S-Corps in high tax states, the PTET election can move a meaningful amount of state tax above the SALT cap and into a federal deduction. How much depends on state rates and income. Each state's version has different:
Election deadlines (some require election before the tax year begins)
Payment schedules
Credit mechanics on the individual return
Interaction with estimated tax payments
The PTET election is a separate decision from the S-Corp election itself, but they interact. Your tax team should model both together.
What Does S-Corp Compliance Actually Require?
Payroll, Bookkeeping, and the Separate Tax Return
Electing S-Corp status means you are committing to a higher level of administrative overhead. This is not optional. It is the cost of the FICA benefit.
What changes when you elect S-Corp:
You must run payroll for yourself (and any employees), including W-2s, quarterly 941 filings, and state payroll tax filings
You must file a separate S-Corp tax return, Form 1120-S, annually (due March 15 for calendar-year S-Corps)
Each shareholder receives a Schedule K-1 showing their share of S-Corp income, deductions, and credits
You need to maintain separate books for the S-Corp, tracking income, expenses, officer compensation, and distributions
Shareholder distributions must be tracked against stock basis to ensure they are not taxable
For a solo physician, this typically means:
A payroll provider (Gusto, Rippling, or ADP run $50 to $150/month for a solo S-Corp)
A bookkeeper or bookkeeping service
A tax preparer who files the 1120-S in addition to your personal 1040
What Should You Budget for Annual Compliance?
A rough budget for annual S-Corp compliance:
Compliance item | Typical annual cost |
Payroll service | $600 to $1,800 |
Bookkeeping (varies with transaction volume) | $2,400 to $6,000 |
S-Corp tax return preparation (Form 1120-S) | $1,500 to $3,000 |
State S-Corp or franchise tax filings (state-dependent) | $500 to $2,000 |
Workers' compensation insurance (required in most states) | $500 to $2,000 |
Total annual compliance overhead | roughly $5,500 to $14,800 |
These costs are deductible business expenses, but they still represent real cash flow. The S-Corp election only pencils when the FICA reduction exceeds compliance costs by a meaningful margin.
What Triggers IRS Scrutiny of an S-Corp?
The missteps we see most often across physician clients:
Setting salary unreasonably low relative to specialty benchmarks
Forgetting to run payroll entirely (taking all income as distributions with zero W-2)
Missing quarterly payroll tax deposits and incurring penalties
Filing the 1120-S late (the penalty is $255 per shareholder per month for 2026 returns, and it adds up fast)
Not maintaining a separate business bank account for the S-Corp
Commingling personal and business expenses
Failing to document shareholder basis for distributions
Any one of these can trigger an IRS notice or audit. All of them are preventable with proper setup and ongoing bookkeeping discipline.
When Does the S-Corp Election Not Make Sense?
Income Below the Break Even Threshold
The S-Corp election has a break even point. Below it, the compliance costs (payroll, bookkeeping, separate tax return) exceed the FICA reduction.
The exact break even varies by state, specialty, and practice complexity, but as a general guideline:
Net income | What it usually means |
Below $80,000 | The election almost never pencils; the FICA reduction is too small to cover compliance costs. |
$80,000 to $120,000 | Borderline. Run the numbers for your situation; in high cost states like California the break even may be higher. |
Above $120,000 | The election likely pencils for most specialties, assuming reasonable compensation is set properly. |
These are not hard cutoffs. A physician earning $90,000 in a low cost state with a simple practice might benefit. A physician earning $110,000 in California with two state registrations might not. The break even is a function of projected benefit minus projected costs, not a single income number.
Late Career or Winding Down Physicians
If you are within two to three years of retirement or winding down your practice, electing S-Corp status may not be worth the setup effort and ongoing compliance burden. The payback period for S-Corp compliance costs is typically 12 to 18 months. If you do not expect to operate the practice long enough to recoup that investment, the election adds complexity without sufficient return.
Additionally, unwinding an S-Corp at retirement (distributing assets, closing payroll accounts, filing final returns) has its own costs and timeline.
Multi-State Locums with Unpredictable Income
Locum physicians who work in five or more states per year face a unique challenge with the S-Corp election. Each state where you perform services may require:
S-Corp registration or qualification
State level S-Corp tax returns
State payroll tax registration and filings
Separate PTET elections in each state
The compliance costs can stack quickly. A locum physician working in eight states may find that the state by state filing burden eliminates the FICA benefit.
This does not mean locum physicians should never elect S-Corp. It means the analysis must factor in the multi-state compliance costs. Some locum physicians find it worthwhile to elect S-Corp in their home state and treat the other states as incidental filing obligations. Others find the complexity not worth it.
How Do You Elect S-Corp Status (and Fix a Missed Deadline)?
Filing Form 2553: Timing and Requirements
To elect S-Corp status for the current tax year, you must file Form 2553 with the IRS by March 15 (for calendar year entities). Specifically, the form must be filed no later than two months and 15 days after the beginning of the tax year.
For new entities, you have two months and 15 days from the date of formation to file Form 2553 and have the election effective from day one.
Requirements for a valid S-Corp election:
The entity must be a domestic corporation or LLC that has elected to be treated as a corporation
All shareholders must be eligible (individuals, certain trusts, estates, but not partnerships, corporations, or non-resident aliens)
The entity can have no more than 100 shareholders
Only one class of stock is permitted (you can have voting and non-voting shares, but economic rights must be identical)
All shareholders must consent to the election by signing Form 2553
For most solo physician LLCs, these requirements are easily met. The main stumbling block is the deadline.
Late S-Election Relief Under Rev Proc 2013-30
Missed the March 15 deadline? You are not necessarily out of luck. Revenue Procedure 2013-30 provides a simplified method for late S-Corp election relief.
To qualify, you must demonstrate that:
The entity intended to be classified as an S-Corp as of the effective date
The failure to file Form 2553 on time was due to reasonable cause (not willful neglect)
The entity has been operating consistently with S-Corp treatment (paying yourself a salary, filing as an S-Corp, etc.)
You are filing within 3 years and 75 days of the intended effective date
In practice, the IRS grants late election relief frequently under Rev Proc 2013-30, especially when the taxpayer can show they were acting in good faith. Common reasonable cause explanations include:
The taxpayer's tax preparer failed to file the form
The taxpayer was unaware of the filing requirement
The form was filed but the IRS lost it or returned it for a technical deficiency
Your tax team should prepare the late election request with a supporting reasonable cause statement. It is not a guaranteed approval, but the success rate is high when the facts support it. We walk through the steps, including sample reasonable cause language, in Late S-Corp Election Relief (Rev. Proc. 2013-30).
Revoking an S-Corp Election If Your Situation Changes
S-Corp elections are not permanent. You can revoke the election if your circumstances change. Common reasons physicians revoke include:
Net income drops below the break even threshold
The physician joins a group practice and the solo S-Corp is no longer needed
The practice is restructuring to add non-eligible shareholders (such as a corporate investor)
The multi-state compliance burden becomes unsustainable
To revoke, shareholders holding more than 50% of the stock must consent in writing. The revocation must be filed with the IRS. The effective date depends on when you file:
Filed by March 15: effective for the current tax year
Filed after March 15: effective the following tax year (unless you specify a prospective date)
Once revoked, the entity reverts to its default tax classification (C-Corp for a corporation, or disregarded entity/partnership for an LLC, depending on the number of members). Note: if you revoke an S-Corp election, you generally cannot re-elect S-Corp status for five years without IRS consent. The revocation mechanics and the five year rule are covered in Revoking an S-Corp Election.
Your S-Corp Decision Framework
The Five Questions to Ask Before You Elect
Before you file Form 2553, work through these five questions with your tax team:
Is your net self employment income consistently above $80,000 to $120,000? If you are below this range, the compliance costs likely outweigh the benefit. If your income is volatile year to year, model the worst case scenario, not just the best case.
What is the defensible reasonable salary for your specialty, experience level, and geography? Pull the MGMA data. If your net income is close to the specialty median, the salary to distribution split may be too narrow to do much.
What state level costs will the S-Corp election trigger? California, New York City, and New Jersey each add costs that reduce the net benefit. Multi-state physicians need to model each state.
Are you above or below the SSTB phase out for the QBI deduction? If you are in the phase out range, the S-Corp salary decision and the QBI deduction interact. Model both together.
Do you have the administrative infrastructure (or willingness to build it) for payroll, bookkeeping, and a separate tax return? If bookkeeping discipline is not your strength, factor in the cost of outsourcing it. The S-Corp election without proper compliance is worse than no election at all.
Should You DIY or Hire a Physician Focused Tax Team?
Some physicians handle S-Corp setup and ongoing compliance themselves, using payroll software, bookkeeping tools like QuickBooks, and a tax preparer at filing time. This can work, especially for straightforward solo practices in a single state with predictable income.
But the DIY approach breaks down when:
You practice in multiple states
Your income fluctuates significantly year to year
You have both W-2 and 1099 income in the same year
You are in the QBI phase-out range
You need to work through a late election, revocation, or entity restructuring
In those cases the details stack up quickly, and the difference between a clean election and an expensive compliance problem comes down to getting them right.
What to Do Next
If you are a 1099 physician earning above $100,000, the S-Corp election is worth running the numbers on. The earlier in the year you model it, the more runway you have to elect on time and set up the right infrastructure.
Doc Wealth is physician founded, and our tax team of Tax Attorneys, CPAs, and Enrolled Agents works with thousands of physicians across all 50 states on exactly this decision. We model the FICA math, set reasonable compensation by specialty, work through the state level traps, and handle the ongoing compliance so you can focus on practice. This is proactive, year round tax planning, not a once a year filing, which means when a deadline or question comes up you get prompt, dependable communication from the team that already knows your file.
FAQs
How much does an S-Corp election typically reduce a physician's taxes?
The benefit depends on the gap between net income and reasonable compensation. The wider the spread between a physician's net income and a defensible salary, the more the election does, because more of the income lands as distributions that skip the FICA layer. Compliance costs (payroll, bookkeeping, a separate tax return) run $5,500 to $15,000 per year, so the net result comes down to whether the FICA reduction clears those fixed costs by a comfortable margin. The actual figure requires modeling your own income, specialty, and state.
Can I elect S-Corp status mid-year?
New entities can elect S-Corp status effective from their formation date if they file Form 2553 within two months and 15 days. Existing entities that miss the January 1 effective date can request late election relief under Revenue Procedure 2013-30 or wait until the following tax year.
Does every physician benefit from an S-Corp election?
No. Physicians with net income below $80,000 to $100,000, those winding down their practice, and multi-state locum physicians with unpredictable income may find the compliance costs outweigh the benefit. The election must be modeled based on your specific income, specialty, and state.
What is the penalty for setting my S-Corp salary too low?
The IRS can reclassify distributions as wages, triggering back payroll taxes (both the employer and employee shares), failure to deposit penalties, and interest. In severe cases, the IRS may also assert accuracy related penalties (20% of the underpayment).
Can I have an S-Corp and a solo 401(k)?
Yes. The S-Corp structure works well with a solo 401(k). Your W-2 salary serves as the basis for employee elective deferrals, and the S-Corp can make employer profit sharing contributions. The combination is one of the most common retirement planning structures for 1099 physicians.
How long does it take to set up an S-Corp?
If your LLC is already formed and you have an EIN, the S-Corp election itself is a single form (Form 2553). The IRS typically processes it in 60 days. The operational setup (payroll, bookkeeping, banking) takes an additional two to four weeks. Total timeline from decision to fully operational: roughly 30 to 90 days.
What happens to my S-Corp if I move to another state?
You may need to qualify (register) your S-Corp in the new state and potentially withdraw from the old state. Each state has different requirements for foreign entity qualification, annual report filings, and franchise taxes. Moving states does not automatically affect your federal S-Corp election, but the state level costs and benefits change.
