What Is an S-Corp and Should a Solo Attorney Practice Use One?
Learn what an S-corp is, its tax benefits and costs for solo attorneys, and how to decide if it's right for your practice in 2026.
An S-corp is a tax election that allows a solo attorney to avoid self-employment taxes on a portion of their income, but it comes with added administrative costs and payroll requirements. For many solo attorneys, the savings start to outweigh the costs once net income exceeds roughly $80,000 to $100,000 per year. This guide explains how S-corps work, what they cost, and how to decide if one is right for your practice.
How an S-Corp Works for a Solo Attorney
An S-corp is not a business entity type like an LLC or corporation. It is a tax status you elect with the IRS (Form 2553) after forming an LLC or corporation. As a solo attorney, you typically form a single-member LLC and then elect S-corp status. The key benefit is that you split your income into two parts:
- Reasonable salary: You pay yourself a salary, which is subject to payroll taxes (Social Security and Medicare, totaling 15.3% for the employer and employee portions).
- Distributions: Remaining profits are paid as distributions, which are not subject to self-employment tax. You still pay income tax on distributions, but you avoid the 15.3% payroll tax on that portion.
For example, if your practice nets $120,000 and you set a reasonable salary of $80,000, you pay payroll taxes on $80,000 and only income tax on the remaining $40,000. That can save you around $6,120 per year (15.3% of $40,000) compared to a sole proprietorship or LLC taxed as a sole proprietorship.
Cost and Complexity of an S-Corp
S-corp status is not free. You must run payroll, file additional tax returns, and follow strict rules. Here are the typical costs in 2026:
| Cost Item | Estimated Annual Cost |
|---|---|
| Payroll service (e.g., Gusto, ADP) | $50-$100/month ($600-$1,200/year) |
| Additional tax preparation (Form 1120-S) | $500-$1,500/year |
| State filing fees (if applicable) | $0-$300/year |
| Potential unemployment insurance | Varies by state, $100-$500/year |
| Total additional cost | $1,200-$3,500/year |
You also need to:
- Run payroll on a regular schedule (e.g., monthly or biweekly).
- File Form 1120-S (S-corp tax return) by March 15.
- Pay yourself a “reasonable salary” based on what other attorneys in your area earn for similar work. The IRS requires this to avoid abuse.
- Keep separate records for salary and distributions.
When an S-Corp Makes Sense for a Solo Attorney
An S-corp is most beneficial when your net income is high enough that the tax savings exceed the extra costs and hassle. Here are general thresholds based on 2026 data:
- Below $50,000 net income: Not worth it. The costs eat up most of the savings.
- $50,000-$80,000: Marginal. You might save $1,000-$3,000, but the administrative burden may not be worth it.
- $80,000-$100,000: Usually worth considering. Savings often range from $3,000-$6,000.
- Above $100,000: Strongly consider it. Savings can exceed $7,000, and the costs are a small fraction.
Keep in mind that you must pay yourself a reasonable salary. If you set your salary too low, the IRS can reclassify distributions as wages and impose penalties. A common rule of thumb is to pay yourself 60%-80% of net income as salary, but this varies by practice area and location.
Steps to Decide and Implement an S-Corp
If you’re considering an S-corp, follow these practical steps this week:
- Estimate your net income: Look at your last 12 months of profit (after expenses but before taxes). If it’s below $80,000, hold off.
- Run a cost-benefit calculation: Use a simple spreadsheet. Estimate your tax savings (15.3% of the amount you’d take as distributions) and subtract the additional costs listed above.
- Consult a CPA or tax attorney: They can help you determine a reasonable salary and confirm the election is right for your situation. Expect to pay $200-$500 for a consultation.
- If you decide to proceed: Form an LLC (if you don’t already have one), then file Form 2553 with the IRS. You must file within two months and 15 days of the start of the tax year, or by March 15 for the current year.
- Set up payroll: Choose a payroll service like Gusto or ADP, and schedule your first payroll run. You’ll need to register for an EIN if you don’t have one.
Alternatives to an S-Corp
If an S-corp doesn’t fit, consider these alternatives:
- Sole proprietorship: No extra costs, but you pay self-employment tax on all income. Best for low-income practices.
- Single-member LLC: Similar to sole proprietorship for tax purposes, but offers liability protection. No payroll required.
- C-corp: Rarely used by solo attorneys due to double taxation, but may be useful if you plan to reinvest heavily or seek investors.
- Partnership: Only if you have a partner, but not relevant for solo.
FAQ
Can I switch back from an S-corp to an LLC? Yes, but you must wait five years before re-electing S-corp status after revoking it. Also, there may be tax consequences, so consult your CPA.
What is a reasonable salary for a solo attorney? It depends on your practice area, location, and experience. For example, a family law attorney in a mid-sized city might earn $80,000-$120,000, while a public defender contractor might earn $60,000-$80,000. Use salary data from the Bureau of Labor Statistics or your state bar association.
Do I need to pay myself a salary if my practice loses money? No, but you must pay yourself a reasonable salary if you have profits. If you have losses, you can take no salary, but you must still file the S-corp return.
How long does it take to set up an S-corp? Forming an LLC takes 1-2 weeks, and the S-corp election takes about 60 days to process. Plan ahead if you want to start at the beginning of the tax year.
The Bottom Line
An S-corp can save a solo attorney thousands in taxes each year, but only if your net income is high enough to justify the costs and complexity. For most solo attorneys earning under $80,000, the added expenses and paperwork aren’t worth it. Above $100,000, the savings are significant. Talk to a CPA, run the numbers, and make an informed decision based on your specific situation.
