New Np Practice Buyer's Guide: What to Look For
A practical guide for new nurse practitioner practices on choosing the right tax structure, with a comparison of options, costs, and steps to take now.
Starting a nurse practitioner (NP) practice is exciting, but the business side, especially taxes, can be overwhelming. Your choice of tax structure affects how much you pay, how you file, and your personal liability. This guide compares the most common options for new NP practices, with realistic 2026 figures, so you can make an informed decision.
Why Your Tax Structure Matters
Your tax structure determines how the IRS treats your practice’s income, what forms you file, and how you pay self-employment taxes. For most new NP practices, the choice comes down to sole proprietorship, LLC (taxed as sole prop or partnership), S corporation, or C corporation. Each has different costs, paperwork, and tax implications. Getting this wrong can cost you thousands in extra taxes or legal exposure.
Comparison of Tax Structures for NP Practices
Here is a side-by-side comparison of the most common structures for new NP practices in 2026. Prices are monthly or annual ranges based on current market data.
| Structure | Setup Cost | Annual Maintenance | Tax Filing Complexity | Self-Employment Tax | Liability Protection | Best For |
|---|---|---|---|---|---|---|
| Sole Proprietorship | $0 | $0 | Low (Schedule C) | Full 15.3% on all profits | None | Solo NP testing the waters |
| Single-Member LLC | $50-$500 (state filing) | $0-$300 (state fees) | Low (Schedule C, same as sole prop) | Full 15.3% on all profits | Limited (if you maintain separation) | Solo NP wanting liability protection |
| Multi-Member LLC (Partnership) | $50-$500 (state filing) | $0-$300 (state fees) | Medium (Form 1065, K-1s) | Full 15.3% on all profits | Limited | Two or more NPs |
| S Corporation | $50-$500 (state filing) + $100-$200 (incorporation) | $100-$500 (state fees) + $1,000-$2,000 (payroll service) | High (Form 1120-S, payroll filings) | Only on reasonable salary, not distributions | Limited | Established NP practice with profits over $40,000 |
| C Corporation | $50-$500 (state filing) + $100-$200 (incorporation) | $100-$500 (state fees) + $1,000-$2,000 (payroll service) | High (Form 1120) | Not applicable (corporate tax) | Limited | NP practice planning to reinvest profits or seek investors |
Note: Setup costs vary by state. For example, California charges $800 annual franchise tax for LLCs and corporations, while states like Texas have no state income tax but higher filing fees.
Sole Proprietorship: The Simplest Start
If you’re a solo NP just starting, a sole proprietorship is the default. You don’t need to file anything extra; you just report income on Schedule C of your personal tax return. You pay self-employment tax (15.3% in 2026) on all net profits, plus your marginal income tax rate. This is the cheapest option, but you have no liability protection. If a patient sues, your personal assets are at risk.
Action step: If you’re earning under $20,000 in your first year and have no significant assets, this may be fine. But consider an LLC once you grow.
Single-Member LLC: Liability Protection Without Extra Tax
An LLC gives you limited liability, meaning your personal assets are protected from business debts and lawsuits (in most cases). For tax purposes, a single-member LLC is a “disregarded entity,” so you file the same as a sole proprietor: Schedule C. You still pay full self-employment tax on all profits. The cost is the state filing fee, which ranges from $50 to $500, and sometimes an annual report fee.
Action step: If you have any patient interaction, an LLC is a smart move. It’s cheap and simple. Check your state’s LLC filing fee and annual report requirements.
Multi-Member LLC: For Partnerships
If you’re starting with another NP, a multi-member LLC is taxed as a partnership by default. You file Form 1065 and issue K-1s to each partner. Each partner pays self-employment tax on their share of profits. This adds complexity, but it’s still simpler than an S corp. The setup cost is similar to a single-member LLC, but you’ll need a partnership agreement.
Action step: If you have a partner, consider a multi-member LLC. Hire a CPA to draft the partnership agreement and handle the K-1s.
S Corporation: Tax Savings for Established Practices
An S corporation is a corporation that elects to pass income through to shareholders. The key benefit: you pay yourself a “reasonable salary” (subject to payroll taxes), 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 you thousands. However, you must run payroll, file Form 1120-S, and pay state fees. The IRS requires that your salary be reasonable; if it’s too low, you risk penalties.
The break-even point is typically when your net profit exceeds $40,000 to $50,000. Below that, the payroll costs and complexity outweigh the savings.
Action step: If your practice is profitable and you’re taking home over $40,000, talk to a CPA about whether an S corp election makes sense. You’ll need to file Form 2553 with the IRS.
C Corporation: Rarely the Best for New NPs
A C corporation is a separate tax entity. It pays corporate income tax (21% federal in 2026), and dividends are taxed again at the shareholder level. This double taxation is usually a disadvantage for small practices. However, if you plan to reinvest heavily in equipment or seek outside investors, a C corp might be worth considering. The setup and maintenance costs are similar to an S corp.
Action step: For most new NP practices, a C corp is overkill. Avoid it unless you have specific reasons, like raising venture capital.
How to Choose: A Practical Decision Framework
- Solo NP, under $40,000 profit: Start with a sole proprietorship or single-member LLC. The LLC is worth the $50-$500 for liability protection.
- Solo NP, over $40,000 profit: Consider an S corp election. Run the numbers with a CPA to see if the payroll costs are worth the tax savings.
- Two or more NPs: Use a multi-member LLC or S corp, depending on profit levels. A partnership agreement is essential.
- Plan to reinvest or seek investors: Consider a C corp, but only after consulting a tax advisor.
Action step this week: Estimate your first-year net profit. If it’s over $40,000, book a consultation with a CPA who specializes in healthcare practices. If it’s under, focus on getting an LLC in place.
FAQ
1. Do I need to register my NP practice with the state? Yes, if you choose an LLC or corporation. You’ll file articles of organization or incorporation with your state’s secretary of state. Sole proprietors don’t need to register, but you may need a business license and a DEA number if you prescribe controlled substances.
2. Can I change my tax structure later? Yes. You can start as a sole proprietor and later form an LLC or elect S corp status. There are costs and paperwork, but it’s common as practices grow. For example, you can convert a sole proprietorship to an LLC without tax consequences in most states.
3. What is a “reasonable salary” for an S corp? The IRS doesn’t set a fixed number. It depends on your specialty, location, and hours. For an NP, a reasonable salary might range from $80,000 to $120,000 in 2026, but you should benchmark against similar positions. Your CPA can help.
4. How do I pay self-employment tax? You pay it when you file your personal tax return. The IRS calculates it on Schedule SE, and you pay it as part of your total tax. If you expect to owe over $1,000, you may need to make estimated quarterly payments to avoid penalties.
The Bottom Line
For most new NP practices, a single-member LLC is the best starting point: it’s affordable, provides liability protection, and keeps taxes simple. As your profit grows past $40,000, revisit the S corp option. Don’t overcomplicate things in year one. Focus on providing excellent patient care, keep good records, and consult a CPA before making structural changes. Your tax structure should serve your practice, not the other way around.
