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

Orlando's dental market reflects the broader dynamism of Central Florida's economy: rapid population growth driven by domestic migration from high-cost states, a tourism sector that sustains significant disposable income across the metro, and a healthcare corridor anchored by major hospital systems and medical education. For dental practice owners in Orange County, practice revenues have grown steadily — which means the tax structure of your practice entity is more consequential than ever. The difference between operating as an LLC and operating with S-Corp tax treatment can mean thousands of dollars annually in self-employment tax savings that stay in your practice instead of flowing to the IRS.

This guide walks through the S-Corp vs. LLC comparison specifically for Orlando dental practices: how each structure affects your self-employment taxes, how health insurance deductibility works under each structure, the Florida-specific professional licensing requirements you must account for, and the common mistakes that cost dental practice owners money every year. Use this as a starting framework for the conversation with your CPA and Florida healthcare attorney.

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

The decision between S-Corp and LLC taxation for an Orlando dental practice is fundamentally a self-employment tax question. Under a single-member LLC (default sole proprietorship), 100% of practice net income is subject to self-employment tax — 15.3% on wages up to the Social Security wage base ($176,100 in 2026), then 2.9% above that. Under S-Corp treatment, only the owner's "reasonable salary" is subject to FICA; shareholder distributions above the salary are not. For an Orlando dental practice netting $400,000 after expenses, the SE tax differential between these two structures can be substantial.

LLC Structure for Florida Dental Practices

Single-Member LLC (Default Sole Prop Taxation)

A single-member LLC with one dentist-owner is a "disregarded entity" by default for federal tax purposes. All practice net income flows to Schedule C and is subject to self-employment tax in full. The administrative simplicity is real — no separate payroll required, no W-2 for the owner, no corporate minutes — but the SE tax burden is maximized. For an Orlando dentist netting $350,000, SE tax on the full amount approaches $27,000. That figure drives the S-Corp conversation.

Multi-Member LLC (Partnership Taxation)

When two or more dentists co-own a practice through an LLC, it defaults to partnership taxation. Each partner's share of income is reported on Schedule K-1 and is generally subject to self-employment tax. Multi-member dental practices in Orlando are increasingly common as practice acquisition activity grows — each new partnership agreement should address entity structure and tax treatment explicitly.

LLC Elected as S-Corp

An LLC (or PLLC) can file IRS Form 2553 to elect S-Corp tax treatment at the federal level while remaining an LLC for Florida state law purposes. This is the most popular path for Orlando dental practices that want S-Corp federal tax benefits without forming a separate Professional Association. The PLLC operating agreement governs the practice under state law; the S-Corp election governs federal tax treatment.

S-Corp Advantages for Orlando Dental Practice Owners

Reasonable Salary + Distributions Split

The S-Corp advantage is the salary/distribution split. The owner-dentist pays themselves a reasonable salary for clinical work performed — that salary is subject to FICA payroll taxes. Profits above the salary are taken as shareholder distributions — those are not subject to FICA or SE tax. For an Orlando dental practice netting $420,000, a reasonable salary of $145,000 means only $145,000 is subject to the 15.3%/2.9% FICA rate. The remaining $275,000 in distributions is exempt from SE tax, generating roughly $20,000+ in annual savings compared to full SE tax on all net income.

Self-Employment Tax Savings

The Medicare tax component (2.9%) has no income cap — all wages and SE income above the Social Security wage base continue to be taxed for Medicare. High-producing Orlando dentists — particularly specialists — who push into the $300,000–$600,000 net income range feel the uncapped Medicare tax on their full SE income as a sole prop. S-Corp distributions escape this tax, making the savings grow with practice income.

Health Insurance Deductibility for S-Corp Owners

For majority S-Corp shareholders (over 2%), health insurance premiums must be: (1) paid by the S-Corp or reimbursed to the shareholder; (2) included in Box 1 of the shareholder's W-2 as wages; and (3) deducted by the shareholder on Schedule 1 of their personal return. The deduction is fully available — but only if this exact sequence is followed. Many Orlando dental practices that converted to S-Corp taxation fail to update their payroll processing to reflect this requirement, resulting in a lost deduction on audit.

Health Benefits Through Your Orlando Dental Practice Entity

Group health insurance for your dental practice staff is fully deductible under IRC Section 162 regardless of whether your Orlando practice is structured as an LLC or S-Corp. Employer-paid premiums are an ordinary and necessary business expense. An Orlando dental practice with six staff members paying $625 per month per employee generates $45,000 in fully deductible annual premiums at the corporate or LLC level.

A Section 125 cafeteria plan (Premium Only Plan) allows your dental staff to pay their premium share with pre-tax dollars, reducing your practice's FICA payroll base. This saves the practice 7.65% employer FICA on every dollar employees contribute pre-tax — available under both LLC and S-Corp structures.

For the S-Corp majority shareholder: health insurance premiums must flow through the W-2 before being deducted on Schedule 1. For an LLC sole prop owner: deduct directly on Schedule 1 without W-2 inclusion. Both achieve 100% deductibility when handled correctly.

A High-Deductible Health Plan (HDHP) paired with a Health Savings Account (HSA) allows up to $4,300 (self-only) or $8,550 (family) in 2026 in pre-tax contributions. Employer-funded HSA contributions are deductible to the practice and excluded from employee income — available under both entity types.

Florida-Specific Factors for Dental Practice Entity Selection

• No Florida personal income tax: Florida imposes no personal income tax, so the S-Corp vs. LLC entity choice is a purely federal tax decision for Orlando dental practice owners. All SE tax savings from the salary/distribution split accrue entirely at the federal level.
• Florida professional licensing: Florida dentists must hold their DDS or DMD license individually. Florida allows dental professionals to operate through a Professional Association (PA) or Professional Limited Liability Company (PLLC). A PA can elect S-Corp treatment with IRS Form 2553. General LLCs without professional entity designation may create licensing compliance issues — consult a Florida healthcare attorney before forming your entity.
• Florida corporate income tax: C corporations in Florida pay a 5.5% state corporate income tax. S-Corps and LLCs are pass-through entities and do not pay Florida corporate income tax at the entity level. This is a strong reason to avoid C-Corp structure for Orlando dental practices.
• Central Florida's competitive dental market: Orange County's rapid growth has attracted both individual practitioners and dental service organization (DSO) competition. Practice owners who optimize their entity structure and benefits costs retain more capital to invest in equipment, marketing, and staff retention — compounding their competitive advantage.

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

Common Mistakes Dental Practices Make With Entity Structure

• Paying an unreasonably low S-Corp salary: Depressing the owner salary to maximize distributions is a known IRS audit trigger for dental S-Corps. Reasonable salary must reflect market rates for clinical work performed — document with industry salary data.
• Mishandling S-Corp health insurance through the W-2: The premium must flow through the W-2 — paid or reimbursed by the S-Corp and included in Box 1 — before the owner deducts it on Schedule 1. Practices that switch to S-Corp and fail to update payroll for this treatment lose the deduction on audit.
• Operating as a general LLC without proper professional entity formation: Florida requires dental professionals to use a PA or PLLC. A general LLC may violate Florida Board of Dentistry regulations. Confirm compliance with a Florida healthcare attorney.
• Not establishing a Section 125 plan for staff: Running staff health insurance through payroll without a formal Section 125 plan document means employee contributions are after-tax. The fix is straightforward — most payroll providers can implement a POP document quickly.
• Electing S-Corp without running a breakeven analysis: S-Corp election adds payroll costs, CPA fees for Form 1120-S, and administrative time. For practices netting under $60,000–$80,000, these costs may exceed the SE tax savings. Calculate the net benefit before electing.
