How to Choose a Legal Structure for a New Optometry Practice
Learn the pros, cons, and costs of sole proprietorship, LLC, PLLC, PC, and S corp for optometry practices, plus steps to choose.
Choosing a legal structure is one of the first and most important business decisions you’ll make for your new optometry practice. It affects your taxes, personal liability, and how much paperwork you handle. This guide compares the main options and gives you a clear path to decide.
Why Legal Structure Matters for Optometrists
Your legal structure determines:
- Personal liability: If a patient sues, can they take your house or savings?
- Taxes: How much you pay in self-employment tax, corporate tax, and how you deduct expenses.
- Ownership and investment: Whether you can bring in partners or sell shares.
- State requirements: Some states restrict which structures can provide healthcare services.
As an optometrist, you provide medical services, so you need a structure that protects you from malpractice claims while allowing you to run a business efficiently.
The Main Legal Structures Compared
Here are the five most common structures for optometry practices, with realistic cost ranges for 2026.
| Structure | Liability Protection | Tax Treatment | Setup Cost | Annual Maintenance | Best For |
|---|---|---|---|---|---|
| Sole Proprietorship | None | Pass-through, self-employment tax | $0-$100 | $0 | Testing the waters, low risk |
| General Partnership | None | Pass-through, self-employment tax | $100-$300 | $0-$200 | Two or more owners, low risk |
| Limited Liability Company (LLC) | Yes | Pass-through, can elect S corp | $500-$1,500 | $100-$500 | Most new practices, flexibility |
| Professional Limited Liability Company (PLLC) | Yes | Pass-through, can elect S corp | $500-$2,000 | $100-$500 | States that require PLLC for healthcare |
| Professional Corporation (PC) | Yes | C corp or S corp election | $500-$2,000 | $200-$1,000 | Practices planning to go public or raise capital |
| S Corporation | Yes | Pass-through, salary and distributions | $500-$2,000 (if electing) | $200-$1,000 | Practices with significant profit |
Note: Costs vary by state. For example, California charges an $800 annual franchise tax for LLCs and corporations. Check your state’s fees.
Sole Proprietorship: The Default, But Risky
If you don’t file anything, you’re a sole proprietor. It’s the simplest and cheapest, but you have no liability protection. If a patient sues for malpractice, your personal assets are at risk. Also, you pay self-employment tax on all net income (15.3% in 2026).
When to choose: Only if you’re starting very small and have separate malpractice insurance, and you plan to switch to an LLC or corporation within a year.
General Partnership: For Two or More Owners
If you start with a partner and don’t form an entity, you’re in a general partnership. Each partner is personally liable for the other’s actions. It’s also hard to raise money or sell your share.
When to choose: Rarely. If you have a partner, form an LLC or PLLC instead.
LLC or PLLC: The Most Popular Choice
An LLC gives you liability protection without the formalities of a corporation. You can be a single member or have multiple members. The IRS treats a single-member LLC as a sole proprietorship for taxes, but you still get liability protection.
A PLLC is required in some states (like California, New York, and Oregon) for licensed professionals like optometrists. It’s essentially the same as an LLC but with a different name and filing requirement.
Tax options: You can elect S corporation status for your LLC to save on self-employment taxes. This is common once your practice profits exceed $40,000-$50,000.
When to choose: For most new optometry practices, an LLC or PLLC is the best balance of cost, protection, and flexibility.
Professional Corporation (PC): For Formal Structures
A PC is a corporation formed by licensed professionals. It can be taxed as a C corporation (paying corporate tax) or elect S corp status. PCs require more formalities: board meetings, minutes, and corporate records.
When to choose: If you plan to raise outside investment or eventually go public. For most practices, an LLC is simpler and cheaper.
S Corporation: Tax Savings for Profitable Practices
An S corp is not a separate entity type; it’s a tax election. You can form an LLC or PC and elect S corp status. The benefit: you pay yourself a reasonable salary, and the remaining profits are distributed as dividends, which are not subject to self-employment tax. In 2026, the self-employment tax rate is 15.3%, so this can save thousands.
Cost: You’ll need to run payroll, which costs $50-$150 per month for a service like Gusto or ADP. You also must file Form 2553 with the IRS.
When to choose: Once your net profit is consistently above $40,000-$50,000, the payroll costs are worth the tax savings.
How to Choose: A Step-by-Step Process
Follow these steps this week:
- Check your state’s requirements: Search “[your state] optometry board business structure” to see if a PLLC is required. For example, in Texas, optometrists must form a PLLC or PC.
- Estimate your first-year profit: If you expect under $40,000, an LLC is fine. If you expect more, consider electing S corp status later.
- Talk to a local business attorney: Many offer a free 30-minute consultation. Ask about liability protection and state-specific rules.
- Compare setup costs: Get quotes from online services like LegalZoom ($79 plus state fees) or a local attorney ($500-$1,500).
- Decide on ownership: If you plan to have partners, an LLC or PLLC is easier to manage than a PC.
- File your formation documents: Once you decide, file the Articles of Organization (for LLC) or Articles of Incorporation (for PC) with your state’s Secretary of State.
- Get an EIN: Apply for an Employer Identification Number from the IRS for free at IRS.gov.
FAQ
Q: Can I change my legal structure later? Yes, you can convert from a sole proprietorship to an LLC or from an LLC to an S corp. It’s easier to start with an LLC and elect S corp later than to convert a sole proprietorship.
Q: Do I need a lawyer to form an LLC? No, you can file yourself or use an online service. However, a lawyer can help with partnership agreements and state-specific issues, which is worth the $500-$1,500 fee.
Q: What’s the difference between an LLC and a PLLC? A PLLC is for licensed professionals. Some states require it; others don’t. The main difference is the name and the requirement that all members be licensed in the profession.
Q: How much does it cost to maintain an LLC? Annual costs include state filing fees (typically $50-$300), a registered agent fee ($50-$200), and possibly franchise taxes (e.g., California’s $800). Total: $100-$500 per year.
The Bottom Line
For most new optometry practices, the best choice is an LLC or PLLC. It gives you liability protection, is simple to manage, and allows you to elect S corp status later for tax savings. Start by checking your state’s requirements, then talk to a local attorney. Don’t delay: forming your entity protects your personal assets and sets up your business for success.
