S-Corp vs. LLC Tax Advantages for Dental Practices in Miramar, FL

Miramar's dental market sits within one of Florida's most populated and economically active counties — Broward. With a large and diverse patient base, strong real estate demand, and proximity to both Miami-Dade and Palm Beach markets, dental practices in Miramar can generate substantial revenues. But with higher revenues comes a sharper focus on entity structure: the difference between operating as a default LLC and electing S-Corp taxation can easily represent $10,000 to $30,000 or more in annual federal tax savings for a profitable dental practice owner.

This guide breaks down how LLCs and S-Corps work for Florida dental practice owners, with specific attention to the Miramar and Broward County context. We'll cover self-employment tax mechanics, the reasonable salary requirement, health insurance treatment, Florida-specific entity rules, and the common mistakes that cost dental practice owners money every year. Whether you're starting a new practice or reconsidering your existing structure, this analysis gives you the framework to have a more informed conversation with your CPA.

The Core Question — S-Corp or LLC for Miramar Dental Practices

The LLC vs. S-Corp question for dental practices is fundamentally a self-employment tax question. All net income flowing through a single-member LLC or multi-member LLC to a dentist-owner is subject to self-employment tax — 15.3% on the first $176,100 (2026) and 2.9% on income above that threshold. An S-Corp changes the equation by allowing the owner to draw a salary (subject to FICA) and take additional income as distributions (not subject to FICA). For a dentist earning $300,000 in net practice income, the difference in SE tax treatment can be $15,000 to $25,000 per year.

LLC Structure for Florida Dental Practices

Single-Member LLC — Sole Proprietorship Taxation

A single-member LLC owned by a dentist is treated as a disregarded entity for federal tax purposes. All net income flows directly to the owner's Schedule C (or Schedule E if organized differently), and the entire net profit is subject to self-employment tax. This is the simplest structure administratively — no payroll to run, no separate business return — but it is also the most expensive from an SE tax perspective for a profitable practice. A Miramar dentist netting $250,000 through a single-member LLC pays SE tax on the full amount, reduced only by the deductible half of SE tax.

Multi-Member LLC — Partnership Taxation

If two or more dentists own the practice together through an LLC, the entity is taxed as a partnership by default. The practice files Form 1065 and issues K-1s to each partner. Each partner's distributive share of net income is subject to self-employment tax. Like the single-member LLC, there is no mechanism within default partnership taxation to separate salary from distributions for SE tax purposes — all active partner income is generally subject to SE tax. Multi-member dental LLCs in Broward County often benefit significantly from an S-Corp election.

LLC Elected as S-Corp

An LLC can elect to be taxed as an S-Corp by filing Form 2553 with the IRS. This is the most common structure for profitable dental practices: the legal entity remains an LLC (or a Florida Professional Association), but the tax treatment is S-Corp. The dentist-owner must put herself on payroll at a reasonable salary, file Form 941 quarterly, issue herself a W-2 at year-end, and the LLC files Form 1120-S annually. The savings on SE tax for income above the salary threshold can be substantial for a high-earning Miramar dentist.

S-Corp Advantages for Miramar Dental Practice Owners

Reasonable Salary + Distributions Split

The IRS requires S-Corp owner-employees to pay themselves reasonable compensation — a salary comparable to what the practice would pay a non-owner dentist for the same role and production volume. For a general dentist in Miramar, BLS Occupational Employment Statistics and dental industry compensation surveys typically support salaries in the $150,000–$220,000 range, depending on hours worked and procedure mix. The portion of net income above that salary can be taken as an S-Corp distribution not subject to FICA. Your CPA should document the reasonable compensation determination to withstand IRS scrutiny.

Self-Employment Tax Savings

The combined employee + employer FICA rate is 15.3% on wages up to $176,100 (2026) and 2.9% above that (Medicare only). For a Miramar dentist netting $300,000 and taking a $160,000 salary, the $140,000 distribution avoids FICA entirely. At the blended SE rate for that income band, that's approximately $4,060 in Medicare-only FICA avoided on the distribution (2.9%), plus $0 in Social Security FICA since the salary already reached the wage base. Total SE tax saving on the distribution: roughly $4,060 in this scenario. For practices with net income below the Social Security wage base, savings are much larger because both the 6.2% Social Security and 1.45% Medicare components are avoided on distributions.

Health Insurance for S-Corp Majority Shareholders

S-Corp shareholders who own more than 2% of the company cannot participate in a tax-free employer health plan the same way rank-and-file employees can. Instead, the S-Corp must pay the health insurance premiums directly or reimburse the owner, include the premiums as wages in Box 1 of the W-2 (but not in Boxes 3 and 4 for FICA), and the owner then deducts 100% of those premiums on Schedule 1 of the personal return. This sequence must be followed exactly — skipping the W-2 inclusion means the deduction is disallowed. Properly handled, the self-employed health insurance deduction effectively covers dental, vision, and medical premiums tax-free at the federal income tax level.

Health Benefits Through Your Miramar Dental Practice

Entity structure affects not just SE tax but also how health benefits are structured for the practice. A well-structured benefit plan layers multiple tax advantages simultaneously:

• Group health for staff (IRC §162): Premiums paid for non-owner employees are fully deductible as an ordinary business expense. Broward County small group carriers include Florida Blue, Cigna, Humana, and Ambetter from Sunshine Health.
• Section 125 cafeteria plan: Allows employees to pay their share of premiums with pre-tax dollars, reducing both employee taxable income and employer FICA base. Even a two-dentist practice with a handful of staff benefits materially from a formal Section 125 plan document.
• HSA with HDHP: Pairing a High-Deductible Health Plan with a Health Savings Account allows 2026 contributions of $4,300 (self-only) or $8,550 (family). Employer HSA contributions are deductible; employee contributions are pre-tax. For a Miramar dental practice with a young, healthy staff mix, an HDHP+HSA combination often lowers total premium cost while delivering strong tax benefits.
• ICHRA as alternative: An Individual Coverage HRA lets the practice give employees a monthly allowance to purchase their own individual marketplace coverage. Employer contributions are deductible; employee reimbursements are tax-free. This structure works well for practices with part-time or geographically dispersed staff.

Florida-Specific Factors for Dental Practice Entity Selection

• No Florida personal income tax: Florida imposes no state income tax on individuals or pass-through income. Every dollar of federal deduction or SE tax savings has full impact on your net take-home — there is no state layer to calculate.
• Florida Professional Association (PA): Florida dentists commonly operate through a Professional Association rather than a standard LLC, due to professional licensing requirements under the Florida Dental Practice Act. A PA can elect S-Corp taxation the same way an LLC can, via Form 2553. Check with a Florida-licensed attorney familiar with dental practice ownership rules.
• Florida corporate income tax: Florida imposes a 5.5% corporate income tax on C-corporations. S-Corps are pass-through entities and generally not subject to this tax. This is a significant reason to avoid C-Corp structure for dental practices — double taxation at the federal level plus Florida's corporate tax at the state level.
• Liability and malpractice separation: Both LLC and S-Corp structures provide personal liability protection from practice debts, though malpractice liability for professional acts is treated differently. Dental malpractice insurance remains essential regardless of entity type.

When S-Corp Makes Sense vs. When LLC Alone Is Better

Common Mistakes Dental Practices Make With Entity Structure

1. Setting salary too low: An unreasonably low W-2 salary triggers IRS scrutiny. The IRS has successfully reclassified S-Corp distributions as wages in dental practice cases. Document your salary determination based on industry compensation data for your market.
2. Mishandling S-Corp health insurance: The premium must flow through the W-2 (Box 1 wages, not Box 3/4) before it can be deducted on Schedule 1. Paying the premium outside the S-Corp structure or skipping the W-2 inclusion step disallows the deduction.
3. Missing the S-Corp election deadline: Form 2553 must generally be filed by March 15 of the tax year for which the election is to be effective, or within 75 days of entity formation. Missing this deadline means waiting a full year for the election to take effect.
4. Failing to run payroll: An S-Corp owner who takes only distributions and no W-2 salary has effectively paid no payroll taxes — which the IRS treats as tax evasion if discovered. Proper payroll compliance is non-negotiable.
5. Using C-Corp structure: A dental practice structured as a C-Corp faces double taxation — corporate income tax at the federal level, then dividend taxation when profits are distributed. Combined with Florida's 5.5% corporate tax, this structure is almost never optimal for a dental practice in Miramar.
