Direct primary care economics for family medicine

May 6, 2026 · Pouyan Golshani, MD, Interventional Radiologist

DPC has emerged as a viable practice model for FM. Here’s the membership math, the panel size, and the operating economics. For many family physicians tired of the fee-for-service treadmill, the autonomy and patient-centric focus of Direct Primary Care (DPC) is a powerful draw. But making the leap from a W-2 hospital employee to a small business owner requires a completely different financial playbook. The economics of a DPC practice are intrinsically tied to your personal financial strategy, especially regarding taxation. Success isn’t just about signing up members; it’s about structuring your income and expenses to maximize take-home pay and build wealth efficiently. This involves mastering tax rules that most employed physicians can safely ignore. We’ll break down the core financial strategies that are critical for any physician evaluating or running a DPC practice.

Understanding the 199A QBI Deduction and Its Physician Phase-Out

One of the most significant tax benefits for small business owners is the Section 199A Qualified Business Income (QBI) deduction. In theory, it allows you to deduct up to 20% of your business’s net income from your taxable income, a massive tax savings. However, for physicians, there’s a critical catch: medicine is classified as a “Specified Service Trade or Business” (SSTB).

This SSTB designation means the 20% deduction is subject to a strict income phase-out. For 2026, that phase-out begins at a taxable income of approximately $394,000 for single filers and $787,000 for those married filing jointly. Once your income exceeds these thresholds, the deduction rapidly shrinks and then disappears entirely. Many physicians in high-paying specialties automatically earn too much to ever qualify. But for a family physician starting a DPC practice, your income might fall right in this crucial zone where strategic planning can make or break your eligibility.

Let’s consider a simple example. A DPC owner has a net business income of $350,000 and files a joint return. If their total taxable income is below the $787,000 threshold, they could be eligible for a deduction of up to $70,000 (20% of $350,000). At a 32% marginal tax rate, that’s $22,400 in direct tax savings. If their income creeps just over the phase-out limit, that entire deduction vanishes. This isn’t a gradual tax bracket change; it’s a cliff. The trap most physicians fall into is failing to see this cliff ahead of time and making simple, proactive moves to stay below it.

The Strategy: Managing AGI to Preserve Your 199A Deduction

If your projected income is near or slightly above the 199A phase-out threshold, you don’t have to passively accept losing the deduction. The key is to strategically reduce your Adjusted Gross Income (AGI) using every available tool. Since the 199A deduction is calculated based on taxable income (which comes after AGI-based deductions), every dollar you can defer or deduct is a dollar that helps you stay under the limit.

Here is the tactical sequence for a DPC practice owner:

Max Out Pre-Tax Retirement Accounts: As a business owner, you can establish a Solo 401(k). This allows you to contribute as both the “employee” (up to $24,500 in 2026) and the “employer” (up to 25% of compensation), for a combined total that can exceed $69,000. These contributions directly reduce your AGI.
Utilize a Health Savings Account (HSA): If you have a high-deductible health plan, you can contribute to an HSA. For 2026, the family contribution limit is $8,750. This is another direct, above-the-line deduction that lowers your AGI.
Consider a Cash Balance Plan: For physicians with higher income, a defined-benefit cash balance plan can be layered on top of a Solo 401(k). This can allow you to shelter an additional $100,000 to $300,000+ of pre-tax income per year, dramatically lowering your AGI and almost certainly securing the 199A deduction.
Bunch Charitable Donations: If you make regular charitable gifts, consider “bunching” two or three years’ worth of donations into a single year using a Donor-Advised Fund (DAF). This can push your itemized deductions high enough to make a meaningful impact on your taxable income in the year you fund the DAF.

The planning trap is viewing these as separate, isolated decisions. They are a combined toolkit for AGI management. Failing to max out a Solo 401(k) could be the one move that pushes you over the 199A cliff, costing you far more in lost deductions than the contribution itself.

Rescuing W-2 Deductions with a 1099 Side Hustle

Even before starting a full-time DPC, many employed family physicians can benefit from establishing a small side business. The Tax Cuts and Jobs Act of 2017 (TCJA) eliminated the ability for W-2 employees to deduct unreimbursed business expenses. This means the money you spend on your state license, DEA registration, CME courses, scrubs, and a home office computer is no longer deductible against your hospital salary. For most physicians, this amounts to thousands of dollars in lost deductions each year.

The fix is to generate even a small amount of 1099, or independent contractor, income. This could come from telemedicine shifts, consulting, medical chart reviews, or serving as a medical director. The moment you have 1099 income, you can file a Schedule C (Profit or Loss from Business) with your tax return. This form is where you can deduct all the “ordinary and necessary” expenses related to your profession.

Here’s how it works: Let’s say you earn $5,000 from a few telemedicine shifts. During that same year, you spend $2,000 on CME, $800 on licenses and dues, and $1,200 on a new laptop for work. As a W-2 employee, you could deduct none of this. But with the $5,000 of 1099 income, you can now deduct the full $4,000 in professional expenses on your Schedule C. Your net business income is reduced to just $1,000. You’ve effectively used your professional expenses to make $4,000 of your side income tax-free. This strategy “rescues” deductions that would otherwise be lost forever.

The most common trap is thinking the side hustle isn’t “worth it” for just a few thousand dollars. Physicians often overlook that the primary benefit isn’t just the side income itself, but the tax shield it creates for expenses they were already incurring.

The Solo 401(k): A Supercharger for Side Income and DPC Profits

For any physician with 1099 income—whether from a small side gig or a full-fledged DPC practice—the Solo 401(k) is arguably the most powerful retirement savings vehicle available. It dramatically outperforms the SEP IRA, which is a common but often inferior choice for high-income professionals.

A Solo 401(k) has two components for contributions:

The Employee Contribution: You, as the “employee” of your own business, can contribute up to 100% of your compensation, up to the annual limit ($24,500 in 2026, plus a $8,000 catch-up if you’re over 50).
The Employer Contribution: Your business, as the “employer,” can contribute up to 25% of your compensation.

The total combined contributions cannot exceed a set limit (around $69,000 for 2026, not including catch-up). This structure allows you to save a massive amount of pre-tax money, even on a relatively modest side income. For example, with $50,000 in net 1099 income, you could potentially contribute your entire employee max ($24,500) plus an employer contribution of around $9,290 (roughly 18.6% of net self-employment earnings), for a total of nearly $34,000. A SEP IRA, by contrast, would only allow the employer portion, capping your contribution at around $9,290.

Furthermore, most Solo 401(k) plans allow for Roth contributions on the employee side and permit loans. Crucially, they also allow you to perform a clean “Backdoor Roth IRA” conversion each year. The planning trap here is the “pro-rata rule.” If you have existing pre-tax funds in a traditional IRA (often from rolling over an old 401(k)), any attempt to do a Backdoor Roth conversion becomes a taxable mess. A Solo 401(k) solves this: you can roll those pre-tax IRA funds *into* your Solo 401(k), clearing your IRA balance to zero and enabling clean, tax-free Backdoor Roth IRA contributions year after year.

The HSA Triple-Stack: Your Ultimate Stealth Retirement Account

While a 401(k) is the workhorse, the Health Savings Account (HSA) is the thoroughbred of retirement accounts, offering a unique triple tax advantage that no other account can match.

Tax-Deductible Contributions: The money you put in is tax-deductible in the year of contribution, lowering your AGI. For 2026, the family limit is $8,750.
Tax-Free Growth: The money can be invested in stocks and bonds and grows completely tax-free.
Tax-Free Withdrawals: You can withdraw the money tax-free at any time to pay for qualified medical expenses.

This is where most people stop. But the “stacking” strategy for physicians is to treat the HSA not as a healthcare spending account, but as a stealth retirement account. The key is to pay for all current medical expenses out-of-pocket with post-tax dollars, and *never* touch your HSA funds. Instead, you invest the entire HSA balance for long-term growth and meticulously save all your medical receipts—for decades.

Imagine you contribute the maximum to your family HSA for 20 years. That’s over $175,000 in contributions, which could easily grow to $400,000 or more with market returns. During that same period, you accumulate $100,000 in saved medical receipts for everything from co-pays to dental work to your kids’ braces. In retirement, you can withdraw $100,000 from your HSA completely tax-free by “reimbursing” yourself for those old expenses. The remaining $300,000 continues to grow tax-free. After age 65, any withdrawals not used for medical expenses are simply taxed as ordinary income, just like a traditional 401(k). There is no penalty. This makes the HSA the most flexible and tax-advantaged retirement account in existence.

The trap is using it like a Flexible Spending Account (FSA)—spending the money down each year. By doing so, you forfeit decades of tax-free compound growth, which is where the real wealth is built. The physician finance hub can help model the long-term impact of this strategy against other retirement savings options based on your specific financial inputs.

Transitioning to a DPC model is a major operational and clinical shift, but it’s equally a financial one. Mastering these tax and savings strategies—from preserving the 199A deduction to maximizing your HSA—is what transforms a successful practice into a vehicle for long-term financial independence. These aren’t just marginal gains; they can add up to tens of thousands of dollars in savings each year.
