Real estate for sleep medicine physicians

The 199A Deduction: Protecting Your Pass-Through Income

For physicians with side income from a pass-through entity—like a real estate LLC or a small consulting practice—the Section 199A Qualified Business Income (QBI) deduction is one of the most valuable parts of the tax code. It allows you to deduct up to 20% of your qualified business income. However, there’s a critical catch for physicians: medicine is classified as a “Specified Service Trade or Business” (SSTB). This means the deduction begins to phase out and eventually disappears entirely once your taxable income exceeds certain thresholds.

For 2026, those thresholds are projected to be around $394,000 for single filers and $787,000 for those married filing jointly. While many surgical subspecialists easily surpass these limits, sleep medicine physicians often have an income profile that, with careful planning, can remain under the wire, preserving a deduction worth tens of thousands of dollars.

The strategy is proactive AGI (Adjusted Gross Income) management. Your taxable income is the target, and every dollar you can defer or deduct gets you closer to securing the full 20% QBI. Here’s the sequence:

• Max Out Pre-Tax Retirement Accounts: This is the first and most powerful lever. Contribute the maximum to your hospital 401(k) or 403(b). If you have a 1099 side gig, establish and max out a Solo 401(k) (more on this below).
• Fund Your Health Savings Account (HSA): Contribute the family maximum ($8,750 for 2026) to your HSA. This is a direct, above-the-line deduction that lowers AGI.
• Bunch Charitable Contributions: Instead of donating smaller amounts annually and missing the standard deduction threshold, “bunch” several years’ worth of donations into a single year. By contributing to a Donor-Advised Fund (DAF), you get the full, large deduction in the current year to lower your AGI, but you can grant the funds to your chosen charities over the subsequent years.

The planning trap here is passivity. Most of us don’t check our projected AGI until November. By then, the window to make meaningful contributions has often closed. You must model your income and deductions mid-year to ensure you stay under the SSTB phase-out cliff.

Cost Segregation: Supercharging Your Real Estate Depreciation

When you buy a rental property, the IRS allows you to deduct its depreciation over time—27.5 years for residential and 39 years for commercial. This is a slow, steady paper loss. A cost segregation study fundamentally changes this timeline. It’s an engineering-based analysis that identifies components of the building that can be depreciated on a much faster schedule.

Instead of treating the entire building as one asset, the study “segregates” items into different categories. For example:

• 27.5-Year Property: The structural components like the foundation, walls, and roof.
• 15-Year Property: Land improvements like landscaping, fencing, and paving.
• 5-Year Property: Personal property like carpeting, appliances, and specialty lighting.

The impact is dramatic. A typical study might reclassify 20-30% of a property’s purchase price into 5- and 15-year property. If 100% bonus depreciation is in effect, you can deduct the entire value of that reclassified property in the first year. On a $1 million apartment building, a cost segregation study could easily generate a $250,000+ paper loss in Year 1. You can run your own scenarios with a real estate investing calculator to see how this impacts cash flow and returns.

However, there’s a crucial hurdle: the passive activity loss (PAL) rules under §469. For most physicians, rental income is considered passive, meaning you can only deduct these large depreciation losses against other passive income. The workaround is for a spouse to qualify for Real Estate Professional Status (REPS). If your spouse spends more than 750 hours per year and more than 50% of their total working time on real estate activities, your rental losses become non-passive. They can then be used to offset your active W-2 income, potentially wiping out a huge portion of your tax bill.

The trap to avoid is using a cheap online service that isn’t based on a true engineering review. The IRS requires a detailed, defensible report. Skimping on the study can lead to a disallowed deduction and penalties during an audit.

Rescue Your W-2 Deductions with a 1099 Side Gig

Most of us remember the frustration when the Tax Cuts and Jobs Act (TCJA) of 2017 eliminated unreimbursed employee expense deductions. Overnight, we could no longer deduct thousands of dollars spent on essential professional costs: CME courses, board exam fees, state license and DEA renewals, medical journals, scrubs, and even the portion of our cell phone bill used for work.

The fix is surprisingly simple: generate even a small amount of 1099 income. Whether it’s from telemedicine, expert witness work, consulting, or a medical directorship, this income is reported on a Schedule C, “Profit or Loss from Business.” This simple form re-opens the door to all the deductions TCJA took away from W-2 employees.

Here’s how it works. Your professional expenses are now considered “ordinary and necessary” for your side business. The CME you take to maintain your primary board certification is also directly relevant to your credibility as a consultant or telemedicine provider. Your DEA license is required for you to practice in any capacity. These expenses are deducted directly against your 1099 income on the Schedule C, reducing the taxable amount. Even if the deductions exceed your side-gig income and create a small loss, that loss can often be deducted against your W-2 income, providing a double benefit.

The critical trap is record-keeping. You cannot simply estimate these expenses. You must maintain meticulous, contemporaneous records and keep business finances entirely separate from personal accounts. Open a dedicated business checking account and credit card for all your 1099-related income and expenses. Commingling funds is the fastest way to have your deductions disallowed under audit.

The Solo 401(k): A Supercharger for Your Savings

That same Schedule C that unlocks your professional deductions also gives you access to one of the most powerful retirement savings vehicles available: the Solo 401(k). This is a retirement plan for self-employed individuals, and you can have one *in addition* to your primary W-2 job’s 401(k) or 403(b).

The contribution structure is what makes it so potent. As the business owner, you can contribute in two ways:

1. As the “employee”: You can contribute up to 100% of your self-employment compensation, up to the annual limit ($24,500 in 2026, plus an $8,000 catch-up if you’re over 50).
2. As the “employer”: You can also make a profit-sharing contribution of up to ~20% of your net adjusted self-employment income.

The total combined contributions cannot exceed a set limit (around $70,000 for 2026). For a physician earning $50,000 in 1099 income, this could mean an additional $30,000+ in pre-tax retirement savings, significantly lowering your AGI and accelerating your path to financial independence. Many Solo 401(k) plans also allow for Roth contributions and after-tax contributions, enabling the “mega backdoor Roth” strategy.

The most common trap is the setup deadline. You must establish the Solo 401(k) plan by December 31 of the tax year you want to make contributions for. While you have until the tax filing deadline (including extensions) of the following year to actually *fund* it, the plan itself must be opened by year-end. Many physicians realize this in January and discover they’ve missed the window for the prior year.

The HSA Triple-Stack: Your Ultimate Stealth Retirement Account

The Health Savings Account (HSA) is often misunderstood as just a way to pay for current medical expenses with pre-tax dollars. For a physician with a stable income, its true power lies in using it as a long-term investment vehicle—a “stealth IRA” with unparalleled tax advantages.

The strategy is known as the triple-stack, for its three distinct tax benefits:

1. Tax-Deductible Contributions: The money you put in is tax-deductible, lowering your AGI. For 2026, the family contribution limit is $8,750.
2. Tax-Free Growth: Unlike a traditional IRA or 401(k), the money inside the HSA grows completely tax-free. You must select an HSA provider that offers low-cost index funds for investment, not just a savings account.
3. Tax-Free Withdrawals: This is the key. You can withdraw money tax-free at any time for qualified medical expenses.

Here’s the execution that turns it into a retirement account: max out your HSA contribution every single year. Invest the entire balance in a diversified, low-cost portfolio. Then, pay for all your current medical expenses—copays, prescriptions, dental—out of pocket with a credit card. 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) labeled by year.

Decades from now, in retirement, you will have a massive, tax-free investment account and a folder full of tens or even hundreds of thousands of dollars in accumulated, unreimbursed medical receipts. You can then withdraw money from the HSA, completely tax-free, up to the total amount of those saved receipts. It becomes a tax-free emergency fund or income stream. After age 65, you can also withdraw from it for any reason, and it’s simply taxed as ordinary income, just like a traditional IRA—but the option for tax-free medical reimbursement never expires.

The trap is spending it. It’s tempting to use the HSA debit card for a $50 copay. But every dollar you spend today is a dollar (and all its future tax-free growth) you forfeit in retirement. The discipline to pay cash now and save receipts is what unlocks the long-term power of the HSA.
