Why Does This Physician Retirement Plan Options CPA Guide Beat Prep Work?

A 1040 with a Schedule C and a few K-1s might bill $500 to $1,500. However, the same physician may have $800,000 of net income. Furthermore, that income sits in the top federal bracket. A properly designed plan can move $150,000 or more out of current tax. As a result, the value you create dwarfs the prep fee. That gap is the whole business case for building a tax advisory practice.

Enrolled agents compete well here. Physicians do not shop for letters after your name. Instead, they shop for someone who understands their income structure. Moreover, most generalist firms never learn this work. Consequently, the field is wide open.

The Math Behind a $15,000 Fee

Fees should track value. Therefore, start with the tax saved. Suppose a physician shelters $180,000 through a layered plan. At a combined 42% marginal rate, that is roughly $75,600 in deferred tax. A $15,000 design fee is 20% of that number. Most physicians accept that ratio without argument.

• Prep-only engagement: $750 per year, no leverage.
• Plan design plus annual review: $15,000 year one.
• Ongoing maintenance: $6,000 to $9,000 per year.
• Ten physicians: a six-figure advisory book.

Who Are the Best Physician Prospects?

Not every doctor fits. Focus on three profiles. First, full 1099 physicians with no employees. Second, locum tenens doctors with volatile income. Third, practice owners with a small, young staff. Each of these groups shows up in our guide for self-employed professionals.

What Are the 2026 Contribution Limits You Must Know?

Every design decision runs through these numbers. Therefore, memorize them. The IRS publishes them each fall in a notice on retirement plan contribution limits. Always confirm the current figures before you sign a plan document.

2026 Limits at a Glance

Item	2025 (prior year)	2026
401(k)/403(b) elective deferral	$23,500	$24,500
Age 50+ catch-up	$7,500	$8,000
Total 415(c) additions	$70,000	$72,000
Countable compensation	$350,000	$360,000
IRA contribution	$7,000	$7,500
415(b) annual DB payout at 62	$280,000	$290,000

Why the Compensation Cap Drives Design

The $360,000 compensation cap for 2026 limits employer contributions. Consequently, a 25% profit sharing allocation tops out near $90,000. However, the 415(c) ceiling of $72,000 still applies per person. Therefore, the binding constraint is usually $72,000, not the percentage. Plan accordingly.

Which Retirement Plan Fits Which Physician?

Plan selection is fact-specific. Nevertheless, a simple matrix covers most cases. Review it with the physician on the first call. Then model the numbers. This is exactly where entity-aware tax planning software saves hours, because it evaluates the 1040 and the entity return together instead of in isolation.

Plan Selection Matrix for 2026

Profile	Best Fit	2026 Shelter Range
1099 doctor, no staff, $250K net	Solo 401(k)	Up to $72,000
1099 doctor, no staff, $700K net	Solo 401(k) plus cash balance	$150,000 to $250,000+
Locum tenens, income swings	Solo 401(k) or SEP-IRA	Flexible to $72,000
Practice owner, 6 staff	Safe harbor 401(k) plus profit share	$72,000 plus staff cost
W-2 hospitalist with side 1099	Second solo 401(k), employer side only	Up to 20% of net SE income

The Mixed W-2 and 1099 Trap

Many physicians hold a hospital job and moonlight. Therefore, they have two plan relationships. The deferral limit of $24,500 for 2026 applies per person, not per plan. However, the 415(c) limit of $72,000 applies per unrelated employer. Consequently, the side gig can still take large employer contributions. Most doctors have never heard this. As a result, it becomes your opening value point.

Document the controlled group analysis. Furthermore, confirm there is no affiliated service group issue. The IRS explains the basics in its overview of one-participant 401(k) plans. Get this wrong and the plan can disqualify.

SEP-IRA Versus Solo 401(k)

A SEP-IRA is simple. However, it allows employer contributions only. Therefore, a doctor with $150,000 of net income reaches roughly $30,000. A solo 401(k) adds the $24,500 deferral on top. As a result, the same doctor can reach about $54,500. Moreover, a SEP balance blocks clean backdoor Roth conversions under the pro-rata rule.

How Does a Cash Balance Plan Work for Physicians?

This is the highest-leverage tool in any physician retirement plan options CPA guide. An actuary sets a pay credit each year. Therefore, an older physician can fund far more than $72,000. The IRS describes the structure in its cash balance plan FAQ.

Age-Based Funding Illustration

The table below shows illustrative ranges only. Actual credits depend on the actuarial certification and the plan document. Always get a formal proposal.

Age	Illustrative Cash Balance Credit	Plus 401(k) Side (2026)
40	$90,000	$24,500 plus profit share
50	$160,000	$32,500 plus profit share
58	$250,000	$32,500 plus profit share

The Commitment Problem

Cash balance plans require funding. Therefore, they suit stable income, not one good year. Advise a three to five year horizon. Moreover, explain that underfunding triggers excise exposure. Physicians with volatile locum income should start with a solo 401(k) instead. Then layer later. Our tax strategy framework sequences these decisions in order.

How Does S Corp Choice Change the Retirement Plan?

 

 

This is where most advisors stumble. An S corp election reduces self-employment tax. However, employer retirement contributions are based on W-2 wages only. Therefore, a $120,000 salary limits the employer share to about $30,000. Meanwhile, a sole proprietor uses net earnings instead. Consequently, the two choices interact.

Break-Even Comparison

Factor	Sole Proprietor	S Corporation
Payroll tax base	All net earnings	W-2 wages only
Retirement base	Net earnings	W-2 wages
Admin burden	Low	Payroll plus 1120-S
Cash balance support	Flexible	Needs higher salary

Reasonable compensation rules still apply. The IRS addresses this in guidance on S corporation compensation. Document your analysis. Furthermore, revisit the salary every year the plan funding changes. Our entity structuring service walks through this coordination.

The Mega Backdoor Roth Layer

Some solo 401(k) documents permit after-tax contributions and in-plan conversions. Therefore, a physician can fill the $72,000 space with Roth dollars. However, most prototype documents do not allow this. Consequently, you must source a custom document. That sourcing step alone justifies a planning fee. Review the rules for designated Roth accounts before you promise anything.

How Do You Price and Deliver This Engagement?

Physicians buy clarity. Therefore, your deliverable matters as much as your math. Produce a branded document. Include the entity recommendation, the plan structure, the funding calendar, and the risks. Moreover, state the assumptions plainly.

A Repeatable Seven-Step Workflow

• Gather two years of returns plus current year projections.
• Map every income stream by classification and payer.
• Run a controlled group and staff census check.
• Model three plan scenarios with 2026 limits.
• Coordinate the entity and salary decision.
• Present the written plan and fee.
• Set a funding calendar and quarterly checkpoints.

Handling the Fee Conversation

Lead with the number. Say the plan defers roughly $75,000 of tax. Then state the fee. Physicians evaluate returns on investment daily. Therefore, a clear ratio closes faster than a feature list. Furthermore, never quote hourly. Hourly pricing caps your upside and invites scope debates.

Uncle Kam in Action: The 1099 Anesthesiologist Engagement

Here is a hypothetical example of how this works in practice.

The Scenario. Imagine a 51-year-old 1099 anesthesiologist in a mid-sized metro area. She has no employees. Her net self-employment income runs about $820,000. Currently, she funds only a SEP-IRA. Her prior preparer charges $900 and files the return without comment.

The Challenge. She sits in the top federal bracket. Moreover, her state adds another layer. The SEP shelters roughly $66,000. However, that leaves well over $700,000 fully exposed. In addition, her SEP balance blocks a clean backdoor Roth. She has no written plan and no funding calendar.

How Uncle Kam Would Approach It. First, we would evaluate an S corp election and set a defensible salary near $250,000. Next, we would open a solo 401(k) with a custom document. Then we would layer a cash balance plan sized by an actuary. Finally, we would roll the SEP balance into the solo 401(k) to clear the pro-rata problem.

Illustrative Numbers. Using 2026 limits, the 401(k) side could absorb $32,500 in deferrals including catch-up. Employer profit sharing could add roughly $50,000. An actuary might certify a cash balance credit near $160,000. Together, that is roughly $240,000 deferred. At a combined 45% marginal rate, she could save roughly $108,000 in current-year tax. These figures are estimates only. Actual results depend on the actuarial certification and her facts.

A $20,000 design fee represents under 20% of that estimated benefit. For real outcomes from similar engagements, see our documented client results.

Frequently Asked Questions

Can an enrolled agent sell retirement plan design?

Yes. Enrolled agents may advise on plan selection and tax effects. However, actuarial certification for a defined benefit plan requires an enrolled actuary. Therefore, partner with one. Also avoid giving investment advice unless you hold the proper license.

What is the 2026 deadline to establish a solo 401(k)?

Under SECURE Act rules, a sole proprietor may generally adopt a plan by the return due date. However, elective deferrals have tighter timing. Consequently, set the plan up well before year end. Confirm current deadlines with IRS guidance.

Does a cash balance plan work with staff?

It can. Nevertheless, nondiscrimination testing requires meaningful staff benefits. Typically, employers fund 5% to 8% of staff pay. Therefore, run a census first. A young, low-paid staff usually makes the economics work well.

How much can a 2026 locum tenens physician defer?

A 1099 locum doctor with a solo 401(k) can defer $24,500 in 2026. Employer contributions may push the total toward $72,000. Those aged 50 and over add $8,000. Actual capacity depends on net self-employment earnings.

What if the physician already has a hospital 403(b)?

The $24,500 deferral limit is shared across plans. However, employer contributions to an unrelated side business generally stand separately. Therefore, the side 401(k) can still receive profit sharing. Verify there is no controlled group link first.

How long does implementation take?

Plan design usually takes two to four weeks. Document adoption and account opening add another two weeks. Consequently, start by early fall for a current-year plan. Rushing in December creates avoidable errors.
