Choosing a Business Entity for Your Solo Practice

The first legal client of your new practice is the practice itself, and its first question is one lawyers famously overthink: what entity should I be? New solos burn surprising amounts of launch energy comparing PLLCs, professional corporations, and sole proprietorships, mostly because the stakes feel existential and the advice online is written for businesses that aren't law firms.

Here's the compressed truth: for a solo attorney, entity choice matters less than new lawyers fear and differently than they assume. It will not protect you from the risk you're most worried about, it will protect you from several you haven't thought about, and the right answer is usually determined by your state's rules more than your preferences. This is the plain-English version, with the standard caveat that entity and tax choices deserve a conversation with your own accountant and your state's specific rules.

What an Entity Does, and Does Not Do, for a Lawyer

Start with the myth that needs retiring. No entity, anywhere, shields you from liability for your own malpractice. Form whatever you like; if you blow a deadline or botch a closing, the injured client can reach you personally. That protection comes from malpractice insurance and careful practice, full stop. Any entity decision made primarily to dodge professional liability is solving the wrong problem.

What a properly maintained entity does protect against is everything else a business generates: the office lease, the equipment financing, vendor contracts, an employee dispute, the slip-and-fall in your waiting room, and, in multi-attorney arrangements later, vicarious exposure for a colleague's conduct. It also provides operational scaffolding: a clean separation between business and personal finances, a professional identity for banking and contracts, and a structure that grows with the practice if you ever add partners or staff.

The Actual Menu

Lawyers don't get the whole entity catalog; most states route professionals into professional variants:

• Sole proprietorship. The default if you do nothing: you and the practice are legally identical. Zero formation cost, zero formalities, zero separation. Viable for a true starting point, but you're personally on every business obligation, and the discipline of separate finances is left entirely to habit.
• PLLC (professional limited liability company). The workhorse where it's available: LLC flexibility, minimal formalities, pass-through taxation by default, and the business-liability shield. Most states offer it to lawyers; a few notably don't, and in those states the corporate form is the path.
• Professional corporation (PC or APC). The older professional form, required or customary in some states. Corporate formalities are heavier (bylaws, minutes, formal payroll), and taxation is either S-corporation pass-through by election or C-corporation by default, almost always the former for a solo.

Which of these your state permits for lawyers, what it must be named, and whether the bar must approve or register it are all state-specific questions with unambiguous answers. Check your state bar's rules and your secretary of state's professional-entity provisions before you compare anything else; in many states the "choice" is nearly made for you.

Taxes in Plain English

For a solo, the tax story is simpler than the internet makes it. A sole proprietorship, a single-member PLLC, and an S-electing PC all land in roughly the same place: the practice's profit flows onto your personal return. The variable that eventually matters is self-employment tax, the roughly 15 percent Social Security and Medicare layer on profit.

The S-corporation election (available to PLLCs and PCs alike) lets you split profit into a reasonable salary, which bears payroll taxes, and a distribution, which doesn't. That split saves real money once profits are comfortably above what a reasonable salary for your work would be, commonly meaningful somewhere north of $75,000 to $100,000 of consistent profit. Below that, the election mostly buys you payroll processing costs, quarterly filings, and IRS attention for no savings. The practical sequencing for most new solos: form the entity now, take the S election later, when the numbers say so and your accountant agrees.

The Formation Checklist

Whichever form you choose, the setup is a half-day of tasks: confirm the name complies with your state's law firm naming rules; file with the secretary of state (and register with the bar where required); get an EIN; open the operating account and the IOLTA in the entity's name; put your malpractice policy in the right name; and calendar the annual report so the entity you formed stays in good standing. Add an operating agreement or bylaws even as a solo, both because banks and future partners will ask, and because it forces the useful discipline of writing down how the practice works.

Then respect the separation you just created. Run every business dollar through the business accounts, sign contracts in the entity's name with your title, and keep the formalities current. An entity treated as a personal checking account with a fancy name offers roughly the protection of one.

The Mistakes Worth Skipping

Four recur. Treating the entity as a substitute for malpractice insurance, when it protects against everything except the thing insurance covers. Copying another attorney's answer from another state, where the professional-entity rules differ. Taking the S election in month one, before there's profit for it to optimize. And forming the entity, framing the certificate, and never maintaining it, no separate finances, no annual reports, until the shield is decorative. Entity choice is a system you operate, not a document you file.

The genuinely local questions, what solos in your state actually form, which banks handle PLLC trust accounts smoothly, when the S election paid off in practice, are exactly the kind of thing Overture's private forums give you a place to ask attorneys who have already lived your state's version of this decision.

Revisit at the Right Moments

Entity choice isn't permanent, and a few practice milestones should reopen the file. Consistent profit above the S-election threshold is the obvious one. Adding your first employee changes the payroll and liability picture, and adding another attorney changes everything: a second owner converts your solo PLLC into a partnership-taxed entity or prompts a restructure, and the vicarious liability protection of the professional form suddenly starts earning its keep. Practicing across state lines raises registration questions, since your entity may need foreign qualification, and your license definitely doesn't travel with the paperwork.

Retirement planning deserves a line here too, because it's the quiet financial advantage of running your own practice. A solo attorney with real profit can shelter substantially more through a solo 401(k) or SEP IRA than most employees ever can, and the entity structure interacts with how contributions work. That conversation, like the S election, belongs with your accountant, but it belongs on your calendar: put an annual entity-and-tax review in the same January slot as your fee review, and the structure keeps pace with the practice instead of trailing it by five years.

The Bottom Line

Pick the professional entity your state offers, usually a PLLC where available, a professional corporation where not, form it cleanly, insure the risk the entity can't touch, and defer the tax cleverness until there's income worth optimizing. Then stop thinking about it and go get clients; the entity question is a gate, not a destination.
