S-Corp vs LLC for New Chiropractic Offices: Which Saves More on Taxes?
Compare S-Corp vs LLC tax savings for new chiropractic offices. See real numbers, steps to choose, and FAQs. Practical guide for 2026.
For a new chiropractic office, the choice between an S-Corp and an LLC can significantly impact your tax bill. In most cases, an S-Corp saves more on self-employment taxes, but only if your net income exceeds a certain threshold. This guide breaks down the numbers, the trade-offs, and the steps you can take this week to make the right decision.
How LLCs and S-Corps Are Taxed Differently
A single-member LLC is taxed as a sole proprietorship by default. You report business income on Schedule C, and you pay both income tax and self-employment tax (Social Security and Medicare) on the entire net profit. For 2026, the self-employment tax rate is 15.3% on the first $176,100 of net earnings, plus 2.9% on earnings above that.
An S-Corp is a corporation that elects pass-through taxation. You must pay yourself a “reasonable salary” as a W-2 employee. You and the corporation each pay 7.65% in payroll taxes on that salary (total 15.3%), but the remaining profits are distributed as dividends, which are not subject to self-employment tax. You still pay income tax on those dividends, but you avoid the 15.3% payroll tax on them.
The Tax Savings: Real Numbers for a Chiropractic Office
Let’s compare two scenarios for a new chiropractor with $120,000 in net profit before owner compensation (after business expenses).
Scenario A: LLC (Sole Proprietor)
- Net profit: $120,000
- Self-employment tax: 15.3% of $120,000 = $18,360
- Income tax (assuming 22% federal bracket, single filer): roughly $26,400 (simplified, ignoring deductions)
- Total federal tax: $44,760
Scenario B: S-Corp
- Reasonable salary: $80,000 (a common range for chiropractors in many regions)
- Payroll tax on salary: 15.3% of $80,000 = $12,240
- Remaining profit: $40,000 (no payroll tax)
- Income tax on salary and profit: $80,000 + $40,000 = $120,000, same as above, roughly $26,400
- Total federal tax: $12,240 + $26,400 = $38,640
Savings with S-Corp: $6,120 per year ($44,760 - $38,640).
However, if your net profit is only $40,000, the S-Corp savings shrink. With an LLC, self-employment tax is $6,120. With an S-Corp, a reasonable salary might be $40,000, so payroll tax is $6,120, and there are no profits left. The savings are zero, but you have the added costs of payroll processing and corporate compliance.
When an S-Corp Makes Sense: The Break-Even Point
The general rule of thumb is that an S-Corp becomes worthwhile when your net profit exceeds $50,000 to $70,000 per year. Below that, the administrative costs and complexity often outweigh the tax savings. For a new chiropractic office, if you’re just starting and expect to earn less than $60,000 in the first year, an LLC may be simpler and cheaper.
The Costs of an S-Corp: What You Need to Budget
S-Corps come with extra expenses that LLCs don’t have:
- Payroll processing: You must run payroll for yourself. Services like Gusto or ADP cost $40-$100 per month, plus employer payroll taxes.
- Unemployment insurance: You’ll pay state and federal unemployment taxes on your salary.
- Corporate filing fees: Some states charge annual franchise taxes or fees, ranging from $0 to $800 (e.g., California).
- Accounting fees: Expect to pay $500-$1,500 more per year for an accountant who can handle S-Corp tax returns and payroll.
Total additional annual cost: $1,500-$3,000 in the first year, depending on your state and payroll provider.
How to Choose: A Step-by-Step Approach
- Project your net profit for the next 12 months. Be realistic. If you’re just opening, use your business plan’s conservative estimate.
- Calculate the potential tax savings using the formula above. Use your expected profit and a reasonable salary estimate (typically 50%-70% of net profit, but check industry norms).
- Estimate the additional costs of an S-Corp (payroll, filing fees, accounting).
- Compare savings vs. costs. If savings exceed costs by at least $1,000, consider an S-Corp. If not, start with an LLC.
- Consult a CPA who works with chiropractors. They can help you set a reasonable salary and run the numbers for your specific situation.
Making the Election: Steps to Take This Week
If you decide an S-Corp is right for you, here’s what to do:
- File Form 2553 with the IRS within 2 months and 15 days of the start of your tax year. If you already have an LLC, you can elect S-Corp status by filing this form.
- Register for payroll with a provider like Gusto or QuickBooks Payroll. Set up your salary and withholdings.
- Open a separate bank account for the corporation if you haven’t already.
- Notify your state of the election. Some states require a separate S-Corp election or have different rules.
- Work with your accountant to ensure you’re compliant with payroll tax deposits and filings.
If you’re not ready, you can start as an LLC and convert to an S-Corp later. The conversion is usually a tax-free event if done correctly.

FAQ
Can I switch from an LLC to an S-Corp later?
Yes. You can file Form 2553 to elect S-Corp status. The conversion is generally tax-free, but you’ll need to meet the deadline (within 2.5 months of the tax year start) and follow state rules.
What is a “reasonable salary” for a chiropractor?
The IRS requires that your salary be reasonable based on your role and industry. For chiropractors, salaries often range from $60,000 to $120,000 depending on location and experience. Your CPA can help you determine a defensible number.
Are there any downsides to an S-Corp besides cost?
Yes. S-Corps require more paperwork, such as holding annual meetings and keeping minutes. You also must run payroll and file additional tax forms. If you miss deadlines, you may face penalties.
What if I have losses in my first year?
If your new practice operates at a loss, an LLC may be better because you can deduct those losses against your other income on your personal return. S-Corp losses also pass through, but the payroll costs may not be worth it if you’re not profitable.
The Bottom Line
For a new chiropractic office, an S-Corp typically saves more on taxes once your net profit exceeds $60,000 per year. Below that, an LLC is simpler and cheaper. The key is to run the numbers with your projected income and realistic costs. Consult a CPA who knows chiropractic practices, and make your decision based on your specific situation, not on general advice. If you’re not sure, start with an LLC and convert later when your practice grows.
