S-Corp vs LLC for New NP Practices: Which Saves More on Taxes?
Compare S-Corp and LLC tax structures for new nurse practitioner practices. See real cost differences, payroll, and savings to decide.
For a new nurse practitioner (NP) practice, the choice between an S-Corp and an LLC often comes down to one question: which saves more on taxes? The short answer: an S-Corp saves more once your net income exceeds roughly $40,000 to $60,000 per year, but only if you factor in the extra payroll costs and administrative work. Below is a concrete breakdown of how each structure affects your tax bill, with real numbers for 2026.
How LLCs and S-Corps Are Taxed Differently
A single-member LLC is a pass-through entity by default. You report business profit on Schedule C of your personal tax return, and you pay self-employment tax (Social Security and Medicare) on 100% of that profit. In 2026, the self-employment tax rate is 15.3%, which includes 12.4% for Social Security and 2.9% for Medicare. On the first $176,100 of net earnings, you pay the full 15.3%; above that, you pay only the 2.9% Medicare portion.
An S-Corp is also a pass-through entity, but it allows you to split your income into two parts: a reasonable salary and distributions. You pay payroll taxes (FICA) on the salary only, not on the distributions. The salary must be “reasonable” for your role, typically what you would pay a non-owner NP in your area. Distributions are not subject to self-employment tax, but they are still subject to income tax.
The Tax Savings Math: When S-Corp Wins
Let’s use a concrete example. Suppose your NP practice nets $80,000 in profit in 2026. As a single-member LLC, you pay 15.3% self-employment tax on the full $80,000, which is $12,240. As an S-Corp, you set a reasonable salary of $50,000 (the average NP salary in many regions). You pay FICA on that salary: 15.3% of $50,000, which is $7,650. The remaining $30,000 is a distribution, which has no payroll tax. Your total payroll tax is $7,650, saving you $4,590 compared to the LLC.
But the S-Corp has additional costs. You must file Form 1120-S (federal) and often a state S-Corp return, which can cost $500 to $1,500 per year in accounting fees. You also need to run payroll, which costs $40 to $100 per month for a service like Gusto or ADP, or $480 to $1,200 per year. Add the accounting fee and payroll, and your total extra cost is roughly $980 to $2,700 per year. In this example, the tax savings of $4,590 still outweigh the costs, leaving a net benefit of $1,890 to $3,610.
However, if your net profit is only $30,000, the math flips. LLC self-employment tax: $4,590. S-Corp: salary of $30,000 (since you must pay yourself a reasonable salary, which might be the entire profit), FICA of $4,590, and no distributions. You save $0, but you still pay the accounting and payroll costs, so you lose $980 to $2,700. That is why the break-even point is typically around $40,000 to $60,000 in net profit.
Comparison Table: LLC vs S-Corp for a New NP Practice
| Factor | Single-Member LLC | S-Corp |
|---|---|---|
| Setup cost (state filing) | $50 to $200 | $50 to $200 (plus $100 to $300 for S-Corp election) |
| Annual compliance cost | $0 to $300 (state annual report) | $500 to $1,500 (accounting for 1120-S) |
| Payroll costs | $0 (no payroll required) | $480 to $1,200 per year (payroll service) |
| Self-employment tax | 15.3% on all net profit | 15.3% on salary only, 0% on distributions |
| Tax savings at $80k profit | $0 baseline | $1,890 to $3,610 net after costs |
| Tax savings at $30k profit | $0 baseline | -$980 to -$2,700 (net loss) |
| Administrative burden | Low (just Schedule C) | High (payroll, quarterly filings) |
Steps to Decide and Implement This Week
- Estimate your net profit for the year. Use your current revenue and expenses. If you are just starting, project conservatively. If you expect to net under $40,000, an LLC is likely the better choice. If over $60,000, an S-Corp may save you money.
- Calculate your break-even point. Use the formula: (Net profit x 15.3%) - (Salary x 15.3%) = potential savings. Then subtract annual S-Corp costs ($980 to $2,700). If the result is positive, consider an S-Corp.
- If you choose an S-Corp, file Form 2553. This must be done within 75 days of forming the LLC or by March 15 of the tax year you want the election to start. Use a service like LegalZoom or a business attorney to ensure proper filing.
- Set up payroll immediately. Use a service like Gusto, which starts at $40 per month. You must pay yourself a reasonable salary, and you must run payroll at least quarterly to avoid penalties.
- Hire a CPA who works with medical practices. They can help you set the right salary and handle the 1120-S. Expect to pay $500 to $1,500 for annual tax preparation.
Common Pitfalls to Avoid
- Setting too low a salary. The IRS requires a reasonable salary. If you pay yourself $20,000 when the market rate is $80,000, you risk an audit and penalties. Use salary data from the Bureau of Labor Statistics or your local NP association.
- Forgetting state-level taxes. Some states, like California, impose a minimum franchise tax on S-Corps ($800 per year). Check your state’s rules before electing.
- Missing payroll deadlines. The IRS charges penalties for late payroll tax deposits. Use a payroll service to automate this.
- Not accounting for retirement contributions. Both structures allow SEP IRAs, but your contribution limit is based on your salary in an S-Corp, not your distributions. This can reduce your retirement savings if your salary is low.
FAQ
Can I switch from LLC to S-Corp later? Yes, you can file Form 2553 at any time, but the election must be effective by the start of the tax year or within 75 days of forming the LLC. If you miss the deadline, you may have to wait until the next tax year.
What is a reasonable salary for an NP in 2026? The average NP salary ranges from $110,000 to $130,000 per year, but for a new practice, you may pay yourself less. A reasonable salary is what you would pay a non-owner NP for the same work, often $50,000 to $90,000 depending on hours and duties.
Do I need to pay myself a salary if my practice loses money? No, if the practice has no profit, you do not need to pay yourself a salary. But if you have profit, you must pay yourself a reasonable salary, even if it means taking the entire profit as salary.
Are distributions taxed differently? Distributions are not subject to self-employment tax, but they are still subject to federal and state income tax. They do not affect your Social Security or Medicare benefits, which are based on your salary.
The Bottom Line
For a new NP practice, an S-Corp saves on taxes only when your net profit exceeds roughly $40,000 to $60,000 per year. Below that, the extra accounting and payroll costs eat up any savings. Above that, the S-Corp can save you thousands annually, but only if you manage payroll correctly and set a reasonable salary. Start by projecting your profit, then consult a CPA to run the numbers for your specific situation. If you are close to the break-even point, an LLC is simpler and safer. If you are clearly above it, the S-Corp is worth the administrative hassle.
