LLC vs. PC for the Solo Practice

Q: How Is a Professional Limited Liability Company Different?

Certain businesses, such as those in the banking and insurance industries, are prohibited from forming an LLC. While some states allow professionals to form an LLC, others require that professionals form a professional limited liability company (PLLC) as set out by state statutes. In a PLLC, the members and managers must be licensed to practice the same profession. In California, licensed professionals are limited to forming a sole proprietorship, general partnership, or professional corporation (PC). One advantage of an LLC is that each owner—also called a member—has limited liability, which means they are not personally liable for the financial obligations of the LLC. Unlike corporations, LLCs do not have to abide by shareholders' directives or hold annual meetings.

Q: what's the main difference between an llc and a pc for solo practitioners?

an llc is simpler to manage and has more flexible tax options, while a pc has stricter rules but may be required by your state. both protect your personal assets from business debts, but they work differently for taxes and paperwork. llcs let you report business income on your personal tax return (like a sole proprietorship), which can help keep things simple. pcs work more like regular corporations, requiring their own tax returns, formal meetings, and record-keeping.

Q: do i have to choose a pc if i'm a licensed professional?

it depends on which state you live in and what type of professional you are. some states require licensed professionals (like doctors, lawyers, and accountants) to use a pc instead of an llc. for example, california generally doesn't let professionals form llcs at all—you must use a pc, sole proprietorship, or partnership. other states allow professionals to form special llcs called pllcs (professional llcs), where all owners must have the same professional license.

Q: will an llc or pc protect me from malpractice lawsuits?

both business structures protect your personal assets (like your house and savings) from general business debts and lawsuits. but if someone sues you for professional negligence or malpractice, they may still go after your personal assets. as a result, you’ll want to purchase malpractice insurance no matter which business structure you choose.

Q: are llcs and pcs taxed differently?

with an llc, your business profits go directly on your personal tax return—there's no separate business tax return to file (unless you opt to be taxed like a corporation). pcs are taxed like regular corporations by default, which means "double taxation." the business pays taxes on its profits, and then you pay taxes again when you take money out as dividends. however, both llcs and pcs can choose s corporation tax treatment, which can help reduce self-employment taxes if you make good money. this is something to discuss with a tax professional based on your income level.

Q: which business structure is easier to manage day-to-day?

llcs are generally easier to manage on a daily basis because they have fewer formal requirements. you don't need to hold annual meetings, keep detailed meeting minutes, or maintain complex corporate records. pcs require more paperwork and formalities, just like regular corporations. you need to hold shareholder meetings, keep meeting minutes, maintain corporate records, and follow specific procedures for major decisions.

Q: what should i do first to decide between an llc and pc?

start by checking your state's laws for your specific profession, since some states will make the decision for you. look up your state's requirements for licensed professionals or contact your professional licensing board. once you know what's legally allowed in your state, consider your priorities. this decision affects your taxes, liability, and daily operations, so it's worth getting professional advice before you file any paperwork—including from a business attorney who knows your state's laws and a tax professional who can explain the financial differences.sarah jones contributed to this article.

What is a limited liability company?

A limited liability company or LLC is a legal entity that combines the limited liability protection of a corporation with the tax benefits of a partnership.

All 50 states and the District of Columbia recognize single-owner LLCs.

Should you choose to incorporate your sole proprietorship as an LLC in the future, you can do so under the IRS “check-the-box" regulations without incurring federal tax consequences.

How is a professional limited liability company different?

While some states allow professionals to form an LLC, others require that professionals form a professional limited liability company (PLLC) as set out by state statutes.

In a PLLC, the members and managers must be licensed to practice the same profession. In California, licensed professionals are limited to forming a sole proprietorship, general partnership, or professional corporation (PC).

In an PLLC, each owner—also called a member—has limited liability, which means they are not personally liable for the financial obligations of the LLC. If someone sues the business or the business defaults on a loan, members’ personal assets can’t be used to settle those debts. Unlike corporations, LLCs do not have to abide by shareholders' directives or hold annual meetings.

What is a professional corporation?

A professional corporation or PC is one variation of a corporation. Licensed professionals who want to incorporate their practice can form a PC.

However, the shareholders, directors, and officers must also belong to the same profession. The list of professions that are required by statute to incorporate as a PC varies by state, so check with your state's corporate filing office—usually the Secretary of State. The following are often required to form a PC:

Accountants
Attorneys
Engineers
Medical doctors
Veterinarians

There are exceptions. Some states give professionals a choice between incorporating as a PC or as a regular corporation. In all states, certain professionals—again, check your state statutes—have the option to form a PC.

The pros and cons of forming a professional corporation

If a professional retires or leaves, ownership is easily transferred to the others, and professionals can share management responsibilities and profits without worrying about being liable for each other's malpractice actions. This flexibility can make PCs a good fit for professionals who aren’t sure they want to stay with the corporation permanently. However, PCs have to pay corporate taxes on what they earn. The flat corporate tax rate could limit corporate growth.

Differences in taxation

There are differences between how an LLC and a professional corporation are taxed. Here’s a quick overview.

How LLCs are taxed

In a single-member LLC, taxes are handled as in a sole proprietorship, and all income passes through the LLC. The owner reports all profits, or losses, as self-employment income on their Schedule C and submits it with the 1040 form in their personal taxes.

LLCs are not required to pay state taxes in most states. The owner pays state taxes on their personal tax return. Check your state statutes to see if your state requires LLCs to pay state taxes.

Additionally, some states impose a fee, often called an annual registration fee, franchise tax, or renewal fee.

How PCs are taxed

Professional corporations pay corporate taxes. This means a sole practitioner gets hit with double taxation, increasing their tax liability each year.

Their income is not only taxed first at the corporate level but also again as personal income. They can deduct corporate expenses, including disability insurance, life and health insurance, and payroll taxes.

Both can file as an S corporation—which is a special type of corporation that is created through an IRS tax election—to avoid double taxation. In an S corp, profits and losses pass through to your personal tax return.

Personal liability

There are similarities between a PC vs. LLC when it comes to personal liability. Both limit an owner's personal liability for business debts and claims to business assets, and creditors cannot come after personal assets.

Neither protects you against personal liability for your own malpractice, negligence, or personal wrongdoing.

However, PCs provide malpractice protection to protect each member from being liable for the wrongdoings of others in the practice. If you’re a solo practitioner, you won’t see a benefit from malpractice protection unless you add additional professionals at a later date.

For many solo practitioners, forming as an LLC is often the better choice. Since they only have to worry about their own actions, the LLC’s liability protection is often enough. Keep in mind that you may want to invest in additional malpractice insurance to fully protect your assets.
