Tax Planning for Solo Medical Practices vs. Group Practices in Miami

zenithtaxpro — Mon, 27 Jul 2026 05:38:20 +0000

If you’re a physician in Miami, the way your practice is structured solo or group changes almost everything about your tax strategy. Entity choice, retirement plan options, compensation structuring, and even how you handle equipment purchases all play out differently depending on whether you’re the only provider signing the checks or one of several partners splitting profits.

At Zenith Tax & Accounting LLC, we work with physicians across Miami who are trying to figure out exactly this: is my current structure still working for me, and what am I leaving on the table?

Solo Medical Practices: Simplicity with Limits

Most solo physicians in Miami start as a single-member LLC or a straightforward S-corp. The appeal is obvious: fewer moving parts, full control over decisions, and a tax setup that’s easy to understand.

Where Solo Practices Tend to Win

S-corp election timing. Once net income comfortably supports a reasonable salary plus distributions, electing S-corp status can meaningfully reduce self-employment tax exposure. The key word is timing—elect too early and payroll costs outweigh the savings; elect too late and you’ve overpaid self-employment tax for years.
Solo 401(k) plans. Without partners to coordinate with, a solo physician can often contribute far more aggressively to a Solo 401(k) or a combined Solo 401(k) plus cash balance plan, sheltering significant income each year.
Section 179 and bonus depreciation on equipment. Imaging equipment, exam room upgrades, and practice technology purchased for a solo practice are fully within one owner’s control to time for maximum deduction in a given tax year.

Where Solo Practices Tend to Struggle

Retirement plan administration costs are spread across one person instead of several, making cash balance plans and defined benefit plans relatively more expensive per dollar sheltered.
Overhead—malpractice insurance, EHR systems, staff isn’t shared, so margins are tighter and there’s less room for error in quarterly estimated tax planning.
Succession and continuity planning (what happens to the practice’s tax position if the physician is out for an extended period) is harder to build around a single provider.

Group Practices: More Complexity, More Levers

Group practices—even a two-physician partnership—open up planning options that simply don’t exist for a solo provider, but they also introduce coordination requirements that can create real problems if ignored.

Where Group Practices Tend to Win

Partner compensation structuring. Guaranteed payments versus profit distributions versus W-2 wages (in a group PC structure) each carry different tax treatment. Getting this mix right across multiple partners compensation structuring is one of the highest-value planning exercises a group practice can do.
Cash balance and defined benefit plans become more efficient. Spreading actuarial and administration costs across several partners often makes these high-contribution retirement vehicles worthwhile in a way they aren’t for a solo provider.
Cost segregation on owned real estate. If the group owns its building, a cost segregation study can accelerate depreciation across a shared asset, benefiting all partners simultaneously.
Ancillary revenue and entity layering. Groups running imaging, labs, or physical therapy alongside core services often benefit from separate entities for those lines, each with its own tax treatment.

Where Group Practices Tend to Struggle

Partner-level K-1 planning gets complicated fast—one partner’s tax situation (real estate losses, a spouse’s income, a Section 199A phase-out) can affect the group’s overall compensation strategy.
Buy-in and buy-out structuring for new or departing partners has tax consequences that are easy to get wrong without a CPA involved from the start.
The Section 199A Qualified Business Income (QBI) deduction phases out at higher income levels for specified service trades or businesses, which includes most medical practices, and this hits group practices with higher aggregate income differently than it hits solo providers.

The Miami-Specific Factor

Miami physicians benefit from Florida’s lack of a state income tax compared to peers in states like New York or California, but that doesn’t eliminate the need for planning—it just shifts the focus entirely to federal strategy: entity structure, retirement plan design, Section 199A optimization, and depreciation timing.

Miami’s higher cost of practice ownership (real estate, staffing, malpractice premiums) also means the stakes on getting entity structure and deduction timing right are higher than in lower-cost markets.

Which Structure Is Right for You?

There’s no universal answer—it depends on income level, number of providers, whether real estate is owned or leased, and long-term succession plans.

A solo practice generating consistent six-figure income may benefit enormously from an S-corp election and an aggressive Solo 401(k) strategy. A three-partner group approaching a real estate purchase may get far more value from a cost segregation study and a cash balance plan than either partner would get planning independently.

The right move is usually a year-round conversation, not a once-a-year tax return conversation.

Ready to Build a Tax Strategy That Fits Your Practice?

Whether you’re a solo physician deciding if an S-corp election makes sense or a group practice trying to structure partner compensation the right way, Zenith Tax & Accounting works with medical practices across Miami to build tax strategies around how your practice actually operates—not a one-size-fits-all template.

What Is the STR Loophole? A Miami CPA Explains

zenithtaxpro — Mon, 25 May 2026 05:38:36 +0000

If you own or are thinking about buying a short-term rental (STR) in Miami, Orlando, or anywhere in Florida, you’ve probably heard the phrase “STR loophole.” Maybe a colleague mentioned it at a dinner party, or you saw it in a real estate investing forum. But what does it actually mean and could it save you thousands of dollars in taxes?

At Zenith Tax & Accounting LLC, Florida’s trusted CPA firm for real estate investors, we field this question every week. The short answer: the STR loophole is a legitimate, IRS-approved tax strategy that when properly executed can allow qualifying property owners to use rental losses to offset W-2 income, business income, or other active earnings.

The longer answer requires understanding exactly how it works, who qualifies, and how to avoid the mistakes that invite IRS scrutiny. That’s exactly what this guide covers.

What Is the STR Loophole?

The “STR loophole” is not a secret trick buried in obscure tax code. It is a well-established set of IRS rules that govern how short-term rental income and losses are classified. Specifically, it refers to the interaction between three things: IRC Section 469 (the passive activity loss rules), Treasury Regulation §1.469-1T(e)(3)(ii)(A) (which defines short-term rental activities), and the material participation rules (which determine whether a rental activity is active or passive).

Here is the core insight: under the IRS passive activity rules, most rental income is considered passive. Passive losses can only offset passive gains they cannot reduce your W-2 salary or self-employment income. That restriction makes rental losses essentially worthless for most high-income professionals.

However, short-term rentals specifically those where the average guest stay is 7 days or fewer are not automatically classified as rental activities under the passive activity rules. This means they are NOT subject to the same passive loss restrictions that hamstring traditional landlords. If you also materially participate in the STR business, those losses become non-passive and can offset your ordinary income.

The STR Loophole in One Sentence: When your average guest stay is 7 days or fewer AND you materially participate in the rental activity, your STR losses are treated as active business losses not passive rental losses allowing them to offset W-2 income, self-employment income, or other active earnings.

Why Does This Matter for Florida Property Owners?

Consider a Miami physician earning $350,000 per year in W-2 income. Under standard passive activity rules, any rental losses from a traditional long-term rental would be trapped as passive and could not reduce that $350,000 of taxable income.

Now consider the same physician who purchases a beachfront property in Miami Beach and rents it on Airbnb with an average stay of 5 nights. She actively manages the property communicating with guests, coordinating cleaners, overseeing maintenance and logs 120 hours of participation during the tax year.

A cost segregation study on her $750,000 property identifies $225,000 in assets eligible for accelerated depreciation. With 100% bonus depreciation restored for 2025 acquisitions, she takes a $225,000 deduction in year one.

Scenario	Without STR Strategy	With STR Strategy
W-2 Income	$350,000	$350,000
STR Depreciation Loss	Trapped (passive)	($225,000) active deduction
Taxable Income	$350,000	$125,000
Estimated Federal Tax Savings	—	~$80,000+

This is why Florida physicians, attorneys, tech executives, and business owners are increasingly adding STRs to their portfolios not just for rental cash flow, but for powerful tax planning potential.

The Two Requirements You Must Meet

The STR loophole has exactly two eligibility gates. Both must be met. There are no shortcuts.

Requirement #1: Average Guest Stay of 7 Days or Fewer

The IRS uses the average period of customer use to determine whether a rental activity is subject to passive activity rules. If the average guest stay across all bookings for the year is 7 days or fewer, the activity falls outside the standard rental definition under Treasury Regulation §1.469-1T(e)(3).

Average Stay	IRS Classification
7 days or fewer	Not a rental activity — passive rules may not apply
8 to 30 days	Rental activity — passive by default
More than 30 days	Traditional rental — passive (Schedule E)

How to calculate average stay: add up the total rental days across all bookings and divide by the total number of bookings. Keep detailed records throughout the year — this calculation is one of the first things the IRS will request in an audit.

Requirement #2: Material Participation

Meeting the 7-day rule removes the activity from the passive rental category, but it does not automatically make your losses active. You must also materially participate in the STR activity.

You participated more than 500 hours during the year.
Your participation constituted substantially all participation by all individuals.
You participated more than 100 hours AND more than any other individual.
The activity is a significant participation activity and your combined significant participation activities exceeded 500 hours.
You materially participated in the activity for any 5 of the prior 10 years.
The activity is a personal service activity in which you materially participated for any 3 prior years.
Based on all facts and circumstances, you participated on a regular, continuous, and substantial basis.

⚠️ Common Mistake: If you hire a full-service property management company that handles everything, that manager’s hours will likely exceed yours — and you will fail the material participation test. Structure your involvement intentionally from day one.

Cost Segregation and Bonus Depreciation: The Engine Behind the Strategy

Meeting the two requirements above unlocks the door. But what actually creates the large tax deductions is the combination of cost segregation and bonus depreciation.

What Is Cost Segregation?

5-year property: carpeting, appliances, certain fixtures
7-year property: furniture, decorative items
15-year property: land improvements, parking, landscaping
27.5-year property: the remaining structural building components

What Is Bonus Depreciation?

Bonus depreciation allows you to immediately deduct 100% of the cost of qualifying property in the year it is placed in service, rather than spreading deductions over years.

Item	Amount
Purchase Price	$800,000
Land Value (not depreciable)	$120,000
Depreciable Basis	$680,000
Cost Seg: 5/7/15-year assets identified	$204,000 (30%)
Year-One Bonus Depreciation (100%)	$204,000 deduction
Remaining on 27.5-year schedule	$476,000

Documentation: The Make-or-Break Factor

The IRS knows the STR loophole is popular. Audit rates for real estate tax strategies have been increasing, and the documentation requirements are strict.

Time Log Requirements

Every entry in your participation log should include: the date, a description of the task performed, the hours spent, who performed the task, and which property the task relates to.

What Counts as Participation Hours?

Guest communication and booking management
Coordinating or supervising cleaners and maintenance
Property inspections and walkthroughs
Purchasing supplies and furniture
Reviewing financials and managing the STR business
Researching improvements and managing vendors
