Telemedicine endocrinology: the practice model rewriting the income story

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

Cash-pay telemedicine endocrinology is becoming a viable full-time model. Here’s the structure, the tax angle, and the patient flow. For many of us in cognitive specialties, the traditional hospital-employed path has felt like the only option, often coming with high patient volumes, administrative burden, and a capped income potential that doesn’t always reflect our expertise. But a direct-to-patient, cash-pay model, supercharged by telemedicine, changes the equation entirely. It’s not just about clinical autonomy; it’s a fundamental rewrite of the financial script for endocrinologists. This article breaks down the key financial and tax strategies that make this model so powerful, moving beyond clinical practice to practice ownership and wealth building.

The 199A Deduction: A Tax Break Endocrinologists Can Actually Claim

Most high-income physicians hear about the Qualified Business Income (QBI) deduction under Section 199A of the tax code and immediately tune out. Why? Because for most specialists, their income blows past the phase-out threshold for a “Specified Service Trade or Business” (SSTB), which explicitly includes the practice of medicine. This phase-out, which begins around $394,000 for single filers and $787,000 for those married filing jointly in 2026, makes the 20% deduction on pass-through income a non-starter for surgeons, radiologists, and cardiologists.

Endocrinology is different. Our typical W-2 compensation often places us squarely in the zone where this deduction is still in play, especially early in our careers or if a spouse has lower income. A cash-pay telemedicine practice, structured as a pass-through entity (like an S-corp or LLC), generates exactly the kind of income the QBI deduction was designed for. If your taxable income is below the threshold, you can deduct 20% of your net business income, a benefit worth tens of thousands of dollars.

Here’s the strategy: actively manage your Adjusted Gross Income (AGI) to stay under that phase-out cliff.

Max Out Pre-Tax Retirement Accounts: Every dollar you contribute to a pre-tax 401(k), 403(b), or a Solo 401(k) from your new practice directly reduces your AGI.
Utilize an HSA: A maxed-out family Health Savings Account contribution ($8,750 in 2026) is another direct reduction to AGI.
Charitable Bunching: If you make regular charitable donations, consider “bunching” several years’ worth of contributions into a single year using a Donor-Advised Fund (DAF). A large, single-year contribution can significantly lower your AGI, potentially pulling you back under the 199A threshold for that year.

The trap most physicians fall into is passive tax planning. They see their gross income, assume 199A is off the table, and leave a massive deduction unclaimed. For an endocrinologist with $150,000 in net income from a telemedicine practice, a 20% QBI deduction is a $30,000 tax savings. It’s a real number, and it’s achievable with proactive AGI management.

Structuring Your Telemedicine Practice for Maximum Tax Efficiency

When you launch a cash-pay telemedicine practice, you’re not just a clinician anymore; you’re a business owner. This shift from a W-2 employee to a 1099 independent contractor (or more accurately, the owner of an S-Corp that pays you) is the single most powerful move you can make for your financial health. The primary reason is the ability to open a Solo 401(k).

A Solo 401(k) is a retirement plan for self-employed individuals. It allows you to contribute as both the “employee” and the “employer.” For 2026, this means you can contribute up to $24,500 as the employee, plus up to 20% of your net self-employment income as the employer, not to exceed a combined total of around $69,000 (this number adjusts for inflation). This is a massive amount of pre-tax savings space on top of any 401(k) or 403(b) you might have at a W-2 job.

Here’s the sequence:

Establish a Business Entity: Work with an attorney or a service to form an LLC. Then, consult with a CPA about making an “S-Corp election.” This allows you to pay yourself a “reasonable salary” (subject to payroll taxes) and take the rest of the profits as a distribution (not subject to self-employment tax).
Open a Solo 401(k): Open this account under your business’s Employer Identification Number (EIN). Major brokerages offer these plans.
Fund It Aggressively: Funnel the profits from your telemedicine practice into this account. The tax deduction from these contributions can easily save you five figures annually, accelerating your path to financial independence.

The planning trap here is analysis paralysis. Many physicians get bogged down in the details of entity selection and never start. The key is to just begin. Even as a sole proprietor filing a Schedule C, you can open a SEP IRA or Solo 401(k). The perfect structure can be refined later; the immediate goal is to start generating 1099 income so you can unlock these powerful retirement and tax vehicles.

Rescuing Lost Deductions: How 1099 Income Fixes the W-2 Problem

One of the most frustrating changes from the Tax Cuts and Jobs Act of 2018 (TCJA) was the elimination of unreimbursed employee expense deductions. Before TCJA, as a W-2 employee, you could deduct costs for CME, medical licenses, DEA registration, scrubs, and professional society dues on Schedule A. After 2018, those deductions vanished for employees.

This is where even a small amount of 1099 income from a telemedicine side practice becomes a financial superpower. The moment you have business income, you can file a Schedule C (Profit or Loss from Business). This form is where you can deduct all the “ordinary and necessary” expenses incurred to generate that income. Suddenly, all those professional expenses that were non-deductible against your W-2 salary become deductible against your 1099 income.

Here’s how it works in practice:

Home Office: The portion of your home used exclusively for your telemedicine practice is now a deductible expense. You can use the simplified method or track actual expenses for a larger deduction.
CME and Education: The cost of conferences, online courses, and subscriptions directly related to maintaining your endocrinology expertise is deductible.
Licenses and Dues: State medical license fees, DEA registration, and dues for organizations like the Endocrine Society are now business expenses.
Equipment: A new computer, a high-quality webcam, a second monitor—all are deductible business expenses needed to run your practice.

The critical planning trap is allocation. You cannot deduct an expense that is 100% for your W-2 job against your 1099 income. However, many expenses have dual utility. Your medical license allows you to practice medicine in both roles. Your CME keeps you current for both. You must make a reasonable allocation of these costs. But for expenses incurred *specifically* for the telemedicine business—like your EMR subscription, HIPAA-compliant video platform, or marketing costs—they are 100% deductible. This strategy can easily turn thousands of dollars in previously non-deductible costs into legitimate deductions that lower your overall tax bill. Once your practice is established, the next challenge is patient acquisition. A well-managed referral pipeline is key, and using a tool like Referral Pulse for practice growth can help streamline and track your outreach to primary care physicians and other specialists.

The HSA Triple-Stack: Your Ultimate Long-Term Investment Vehicle

While not exclusive to telemedicine, the Health Savings Account (HSA) is a financial tool that every physician, especially those building a practice, should be maximizing. It is the only account in the US tax code that offers a triple tax advantage:

Contributions are tax-deductible (pre-tax).
The money grows tax-free.
Withdrawals for qualified medical expenses are tax-free.

Most people, including many physicians, misuse their HSA. They treat it like a checking account for medical bills, spending the money as it comes in. This is a massive missed opportunity. The optimal strategy is to treat the HSA as a super-charged retirement account.

Here’s the “triple-stack” how-to:

Max It Out: Contribute the maximum family amount every single year ($8,750 in 2026). This is a must-do.
Invest It: Do not let the money sit in cash. As soon as the balance clears the minimum threshold (often $1,000), invest the entire amount in low-cost, broad-market index funds. Let it compound, tax-free, for decades.
Stack Receipts: Pay for all current medical expenses out-of-pocket with a credit card (to get the points). Scan and save the receipts in a dedicated digital folder. Do not reimburse yourself from the HSA. Let the account grow. Decades from now, in retirement, you can withdraw money from your HSA tax-free against that accumulated pile of old receipts. It effectively becomes a tax-free emergency fund or a source of income.

The trap is thinking small. A physician who contributes the maximum to an HSA for 30 years and earns a modest 7% annual return could have over $800,000 in the account. That’s $800,000 that can be withdrawn completely tax-free for medical needs in retirement or against a lifetime of saved receipts. It’s arguably the single best investment account available, and it’s hiding in plain sight.

Advanced Strategy: Real Estate and Cost Segregation Studies

As your telemedicine practice grows and your income increases, you’ll want to find more ways to legally and ethically reduce your tax burden. For many physicians, the most effective strategy lies in real estate investing. Specifically, it involves pairing direct ownership of rental properties with two powerful tax code provisions: cost segregation and Real Estate Professional Status (REPS).

A cost segregation study is an engineering-based analysis of a rental property. Instead of depreciating the entire building over 27.5 years (for residential) or 39 years (for commercial), the study identifies components that can be depreciated on a much faster schedule—typically 5, 7, or 15 years. This includes things like carpeting, cabinetry, fixtures, and landscaping. The result is a massive, front-loaded depreciation deduction in the early years of owning a property. It’s not uncommon for 20-30% of a property’s purchase price to be reclassified for accelerated depreciation.

This creates a large “paper loss” on the property. The problem for high-income physicians is that rental losses are typically considered “passive” under IRS §469 and can only offset passive gains, not your active W-2 or business income. This is where REPS comes in. If your spouse can qualify as a Real Estate Professional, your rental losses become non-passive. To qualify, a spouse must:

Spend more than 750 hours per year on real estate activities.
Spend more than 50% of their total working time on real estate activities.
Maintain a contemporaneous log to prove these hours.

When a non-physician spouse achieves REPS and you’ve performed a cost segregation study on your rental portfolio, the magic happens. The huge paper losses from accelerated depreciation are no longer passive. They can be used to directly offset your high ordinary income from your medical practice. This strategy can, and often does, reduce a physician’s tax liability by hundreds of thousands of dollars. You can model out potential returns and depreciation benefits using a real estate investing calculator to see how the numbers might work for your situation.

The trap is thinking this is a casual endeavor. REPS requires a significant, documented time commitment. Cost segregation studies must be performed by a reputable engineering firm. But for the physician family committed to building long-term wealth, this combination is one of the most powerful tax-reduction strategies available.
