Why the Self-Employed Doctors Win by a Landslide On Retirement Plans

The 2026 Retirement Plan Numbers Every Physician Needs to Know — And Why the Self-Employed Ones Win by a Landslide

I converted to an independent contractor through my PC-Employment Lite arrangement over a decade ago. At the time, I understood intellectually that the retirement savings would be better. What I did not fully appreciate was how much better — until I ran the comparison side by side and saw the numbers in one place.

Using a solo 401(k) and Cash Balance Plan combination through my S-Corp, my wife and I were able to contribute nearly four times what I had contributed as a W-2 employee. That difference compounded over the peak earning years of my career, and it is a major reason I was able to reach what I now describe as Coast FIRE — the point where our existing portfolio grows to our retirement target on its own without additional contributions.

This post is an updated version of one I wrote in 2023, with the numbers corrected for the current year: Comparison: Retirement Plans Self-Employed vs. Traditional Employment. The 2026 IRS limits changed meaningfully from 2023, and the framework has expanded with the SECURE 2.0 Act provisions that are now fully in effect. I want every physician in this community to have the accurate current numbers in front of them.

The 2026 Numbers: What the IRS Actually Allows

Let me start with the official limits, sourced directly from IRS Notice 2025-67, published November 2025.

Vehicle 2026 Limit Catch-up (50+) Notes 403(b) / W-2 401(k) employee deferral $24,500 $8,000 Standard employed physician ceiling Super catch-up (ages 60–63, SECURE 2.0) $24,500 $11,250 Higher limit for this age bracket only SEP-IRA up to $72,000 None 25% of compensation; no salary deferral component Solo 401(k) — total (employee + employer) $72,000 $8,000 Salary deferral + 25% profit-sharing Solo 401(k) + Cash Balance Plan combined $150,000+ Actuarially set Age-dependent; highest for physicians 50–65 Traditional / Roth IRA $7,500 $1,100 Income phase-outs apply SIMPLE IRA $17,000 $4,000 For businesses with 100 or fewer employees

What This Means in Practice for Employed vs. Self-Employed Physicians

The table above shows the raw limits. What it does not show is how dramatically those limits translate into different real-world outcomes depending on your structure. Let me make that concrete.

A physician earning $300,000 on a W-2 and maximizing their 403(b) contribution shelters $24,500 in pre-tax retirement savings in 2026. The remaining $275,500 faces their full marginal tax rate before any of it becomes investable. If they are 50 or older, they can add the $8,000 catch-up for a total of $32,500. According to the IRS, the annual contribution limit for employees who participate in 401(k), 403(b), governmental 457 plans, and the federal Thrift Savings Plan is $24,500 for 2026, up from $23,500 in 2025.

That same physician running $300,000 through an S-Corp micro-corporation can structure a reasonable W-2 salary — $180,000, which I recommend as roughly 60 percent of gross income — and contribute both the employee salary deferral ($24,500) and the employer profit-sharing component (up to 25 percent of W-2 compensation, or $45,000), for a solo 401(k) total of $69,500. The remaining $120,000 in S-Corp income comes out as a distribution, avoiding self-employment tax on that portion. And if they layer a Cash Balance Plan on top, total annual retirement contributions can reach $150,000 to $220,000 or more, all deductible at the corporate level.

The difference between $32,500 and $150,000 in annual retirement contributions, at a 35 percent marginal rate, is $41,125 in tax savings per year. Compounded over fifteen years at seven percent, that gap translates to over $1 million in additional retirement wealth. That is the financial consequence of your entity structure — not your income, not your investment choices, not your discipline as a saver. Your structure.

The SEP-IRA vs. Solo 401(k) Question

Physicians who do any 1099 work outside their primary W-2 employment often default to the SEP-IRA for their side income because it is simple to set up. This is an understandable choice — but at meaningful income levels it is a costly one.

The SEP-IRA contribution is capped at 25 percent of net self-employment compensation, up to $72,000 in 2026. There is no salary deferral component and no catch-up provision for physicians over 50. Reaching the $72,000 ceiling requires $288,000 in net self-employment income at the 25 percent contribution rate.

The solo 401(k) reaches the same $72,000 ceiling with significantly less income because it combines two separate contribution mechanisms: the employee deferral ($24,500) and the employer profit-sharing component (25 percent of W-2 compensation). A physician with $150,000 in S-Corp W-2 compensation can contribute $24,500 in salary deferrals plus $37,500 in employer contributions — $62,000 total — while a SEP-IRA at the same compensation level would produce only $37,500. I walked through this specific comparison in my post The Retirement Math Every 1099 Physician Needs to See.

What Traditionally Employed Physicians Do Have — and What It Is Actually Worth

In the interest of a fair comparison, employer-sponsored plans for W-2 physicians do offer real advantages worth naming. Many hospital employers match a portion of 403(b) contributions — typically three to six percent of salary — representing real, free money that self-employed physicians do not receive. For a physician earning $200,000 with a five percent employer match, that is $10,000 per year in matching contributions requiring zero additional effort.

The honest assessment: employer matching is a real benefit that should be captured before optimizing anything else. If your employer matches and you are not contributing enough to receive the full match, that is the first dollar of retirement savings to claim. The employer match is the highest-return investment available to most employed physicians — a 50 to 100 percent immediate return before any market performance is considered.

The equally honest assessment: at physician income levels, the employer match does not offset the structural advantages of self-employment. A $10,000 employer match is meaningful. The $120,000 gap in annual contribution room between a fully leveraged self-employed physician structure and a W-2 403(b) is transformational. These are not equivalent amounts even after accounting for the match.

The SECURE 2.0 Changes Worth Knowing About

The SECURE 2.0 Act of 2022 introduced several changes now fully in effect for 2026 that are relevant specifically to higher-earning physicians.

The super catch-up provision for ages 60 through 63 allows contributions of $11,250 in catch-up savings — higher than the standard $8,000 catch-up for those 50 and older. Under a change made in SECURE 2.0, a higher catch-up contribution limit applies for employees aged 60, 61, 62 and 63. For 2026, this higher catch-up contribution limit is $11,250. If you are in this age bracket, you can defer up to $35,750 to your employer-sponsored plan in 2026.

The Roth catch-up requirement is also now active. Starting in 2026, if your prior-year wages exceed $150,000 in FICA wages, your age-based catch-up contributions to your employer-sponsored retirement plan must be Roth contributions made with after-tax dollars. For high-earning physicians — which describes most of this community — catch-up contributions will now be Roth rather than pre-tax. This eliminates the immediate tax deduction on catch-up amounts for high earners. Discuss this with your CPA before year-end planning.

Where My Wife and I Landed — and the Lesson I Draw From It

After I converted to the PC-Employment Lite model and structured our S-Corp correctly, our combined retirement contributions went from roughly $46,000 per year as W-2 employees to nearly $180,000 using the solo 401(k) and Cash Balance Plan combination. That shift — sustained over the peak earning years of a physician career — is what builds the kind of retirement portfolio that makes financial independence a real outcome rather than an aspirational one.

I am not suggesting that every physician should immediately leave their W-2 arrangement. Many cannot, at least not right away. What I am suggesting is that if you are doing any 1099 work, even on the side, and you are not running it through a properly structured S-Corp with a solo 401(k) in place, you are leaving a significant and quantifiable amount of money in the wrong accounts every year.

Coast FIRE — the point at which your existing portfolio grows to your retirement number without additional contributions — is achievable for more physicians than realize it. The micro-corporation is what makes the timeline realistic. I wrote about this in detail in my post Coast FIRE: A Strategic Path for Self-Employed Doctors to Reduce Burnout and Enhance Autonomy.

Case Study: Dr. Fontaine's Side-by-Side Year

Dr. Fontaine (name protected) is an anesthesiologist in her mid-40s who spent eight years as a W-2 employee before forming a micro-corporation for her locum and consulting income. In the year before she formed the PC, her total retirement contributions — W-2 403(b) maximum — were $24,500. Her employer matched three percent of her base salary, adding another $9,000. Total: $33,500.

In the first full year after forming her S-Corp, she contributed $24,500 in employee deferrals to her solo 401(k) plus $28,000 in employer profit-sharing contributions from her S-Corp, for a solo 401(k) total of $52,500. She also enrolled in a Cash Balance Plan with an actuarially determined contribution of $72,000 at her age and income level. Total retirement contributions that year: $124,500 — nearly four times what she had contributed the prior year.

She lost her employer match. She gained $91,000 in additional tax-deferred retirement savings. At her marginal rate, the net tax savings on the additional contributions exceeded $31,000 — more than three times what the employer match had been worth. "I knew it would be better," she told me. "I did not know it would be this much better."
