Ketamine and TMS clinic economics for psychiatrists

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

Ketamine and TMS clinics have unique reimbursement and ownership dynamics. Here’s how the math works.

As psychiatrists, we’re increasingly seeing opportunities to get involved with interventional psychiatry, not just as referring physicians but as owners, partners, or medical directors. These clinics, focused on Transcranial Magnetic Stimulation (TMS) and ketamine infusions, represent a significant shift in our field. But the financial and operational models are completely different from a traditional private practice or a W-2 hospital job. Understanding the economics is critical, not just for the business’s P&L, but for your personal balance sheet. The new income streams—whether K-1 distributions from a partnership or 1099 payments for directorship—create tax complexities and opportunities that most of us weren’t taught in residency. This article breaks down the key financial strategies you need to master as you evaluate these ventures. For a broader look at the clinical and operational side, you can explore our full suite of psychiatry resources.

Understanding the 199A QBI Deduction for Your Clinic Partnership

One of the most significant tax benefits of owning a piece of a clinic is the Qualified Business Income (QBI) deduction, established under Section 199A of the tax code. In simple terms, it allows owners of pass-through businesses (like an LLC or S-Corp, which most clinics are) to deduct up to 20% of their share of the business’s profit from their personal income taxes. If your clinic partnership generates $100,000 in profit distributed to you, the 199A deduction could be worth up to $20,000, saving you thousands in taxes.

Here’s how it works: The income from the clinic “passes through” to your personal tax return (Form 1040). The QBI deduction is then taken “below the line,” meaning it reduces your adjusted gross income (AGI) but doesn’t lower your self-employment taxes. For a psychiatrist launching a new service line, this is a powerful incentive. It directly rewards the risk of business ownership with a substantial tax break that isn’t available to W-2 employees.

However, there’s a major catch specifically for physicians. The practice of medicine is classified as a “Specified Service Trade or Business” (SSTB). This means the 20% deduction is subject to strict income limitations. Once your personal taxable income exceeds certain thresholds, the deduction begins to phase out and eventually disappears entirely. This is the single biggest trap for physician-owners, and we’ll cover the specific numbers and strategies to navigate it in a dedicated section below.

Using Clinic Directorships or 1099 Work to Rescue W-2 Deductions

Many psychiatrists get involved with a new clinic not as a full partner, but as a medical director or by providing supervision on a 1099 contract basis. This side income, even if it’s just a few thousand dollars a year, is incredibly powerful because it unlocks deductions that were lost to W-2 physicians after the Tax Cuts and Jobs Act (TCJA) of 2018.

Since TCJA, W-2 employees can no longer deduct unreimbursed professional expenses. Think about what you pay for out-of-pocket: your state license renewals, DEA registration, specialty board dues, CME courses and travel, medical journals, even a portion of your cell phone and internet used for work. For a W-2 employee, these are now sunk costs with no tax benefit. The total can easily be $5,000 to $10,000 per year.

The fix is generating any amount of 1099 income. This allows you to file a Schedule C, “Profit or Loss from Business,” with your personal tax return. On that Schedule C, you can deduct all “ordinary and necessary” business expenses against your 1099 income. Those same professional expenses that were non-deductible as a W-2 employee are now fully deductible against your consulting or directorship income. This can effectively make your side-gig income tax-free, or even generate a small paper loss that can offset other income, all while legitimately writing off costs you were already incurring.

Supercharging Retirement with a Solo 401(k)

Once you have that 1099 income from a medical directorship or consulting, you unlock one of the most powerful retirement savings vehicles available: the Solo 401(k), also known as an individual 401(k). This is separate from and in addition to the 401(k) or 403(b) you have at your primary W-2 hospital job.

A Solo 401(k) allows you to contribute as both the “employee” and the “employer” of your own small business (your 1099 gig). This dramatically increases your tax-deferred savings capacity.

Employee Contribution: You can contribute up to 100% of your 1099 compensation, up to the annual employee limit ($23,000 in 2024, likely higher by 2026). This limit is shared with your W-2 plan, so if you max your hospital 401(k), you can’t make an employee contribution here.
Employer Contribution: This is where the magic happens. As the “employer,” you can contribute an *additional* 20% of your net self-employment income. This is new, extra tax-deferred space.

The total combined contributions for 2026 are projected to be around $69,000 (plus a catch-up contribution if you’re over 50). For a psychiatrist with a $50,000 medical directorship gig, you could potentially contribute an extra $10,000 (20% of $50k) into a Solo 401(k), directly reducing your taxable income by that amount. For those with more substantial 1099 income, this strategy can shelter tens of thousands of extra dollars from taxes each year, accelerating your path to financial independence far beyond what a W-2 job alone can offer.

The HSA Triple-Stack: Your Best Long-Term Shelter

Regardless of whether you are a W-2 employee, a clinic owner, or both, the Health Savings Account (HSA) is the most tax-advantaged account in the entire US tax code. It offers a unique triple tax benefit: contributions are tax-deductible, the money grows tax-free, and withdrawals for qualified medical expenses are also tax-free. Most physicians understand the first part, but many miss the strategy to turn it into a powerful retirement vehicle.

Here is the “HSA triple-stack” strategy that every physician should be using:

Max It Out: Contribute the maximum family amount every single year. For 2026, this is projected to be around $8,750. To be eligible, you must be enrolled in a High-Deductible Health Plan (HDHP).
Invest It: Do not use the HSA as a simple checking account for medical bills. As soon as the funds are in the account, invest them in low-cost, broad-market index funds, just like you would in a 401(k) or IRA. Let the money grow and compound tax-free for decades.
Save Receipts, Pay Out-of-Pocket: Pay for all current medical expenses (copays, prescriptions, dental, etc.) with a credit card or after-tax cash. Do not reimburse yourself from the HSA. Instead, scan and save every single medical receipt in a secure digital folder (e.g., Dropbox, Google Drive). There is no time limit on when you can reimburse yourself for these expenses.

The result? Decades from now, in retirement, you will have a massive, tax-free investment account. You will also have an accumulated pile of medical receipts from the past 20-30 years. You can then withdraw money from the HSA completely tax-free up to the total amount of those saved receipts. It becomes a stealth IRA, but better, because the withdrawals are tax-free. This is an essential wealth-building tool for any high-income professional.

The Physician’s Trap: Navigating the 199A SSTB Phase-Out

As we introduced earlier, the 20% QBI deduction has a major limitation for physicians. Because medicine is an SSTB, the deduction begins to phase out once your taxable income exceeds a certain threshold. For 2026, these thresholds are projected to be approximately $393,700 for single filers and $787,400 for those married filing jointly. Once your income is above the top of the phase-out range, the deduction is gone completely.

Most practicing psychiatrists, especially those with a W-2 job plus income from a clinic, will find themselves in or above this phase-out range. This is the trap: the very success that allows you to invest in a clinic can eliminate one of its biggest tax benefits. However, you have some control here, because the limit is based on your taxable income, not your gross income.

This is where strategic AGI management becomes critical. To keep your taxable income below the threshold, you must aggressively use every “above-the-line” deduction available:

Max Out Pre-Tax Retirement Accounts: This is non-negotiable. Max your W-2 401(k)/403(b), your Solo 401(k) from 1099 income, and your HSA. Each dollar contributed here directly reduces your AGI.
Consider a Cash Balance Plan: For high-earning practice owners, a defined-benefit cash balance plan can allow you to shelter an additional $100,000 to $300,000+ per year, pre-tax. This is a powerful tool for drastically reducing AGI.
Charitable Bunching: Instead of donating a set amount each year, “bunch” two or three years’ worth of charitable giving into a single year using a Donor-Advised Fund (DAF). This can help you clear the standard deduction and itemize, further lowering your taxable income in the bunching year.

By strategically lowering your taxable income, you may be able to stay under the SSTB phase-out threshold, preserving a QBI deduction worth tens of thousands of dollars. The decision to build or buy into a practice requires this level of financial planning. If you’re evaluating a potential deal, a formal ASC/OBL feasibility advisory can model these scenarios to clarify the true after-tax return on your investment.

The financial landscape for psychiatrists is changing. Opportunities in interventional psychiatry offer new clinical pathways and significant economic potential, but they demand a more sophisticated approach to personal finance. By integrating strategies like the 199A deduction, 1099-based write-offs, and advanced retirement planning, you can ensure the rewards of these ventures compound effectively on your own balance sheet.
