What is an LLC, and do you actually need one?

A limited liability company is a state-registered entity that legally separates the business from its owners. The practical benefit is liability protection: if the business is sued or defaults on a business debt, creditors generally reach business assets rather than your house and personal savings. Formation happens at the state level, typically costs somewhere between fifty and a few hundred dollars plus an annual report fee, and requires naming a registered agent who accepts legal service on the company's behalf.

The two most common misunderstandings are worth stating plainly. An LLC does not change how you are taxed by default, because a single-member LLC is a disregarded entity and its income flows onto your personal return exactly as a sole proprietorship would; the tax treatment only changes if you separately elect S-corporation status. And liability protection is not absolute. It does not shield you from your own professional negligence or malpractice, from personal guarantees you signed on a lease or loan, or from unpaid payroll taxes. Courts can also disregard the entity entirely, known as piercing the corporate veil, when owners mix personal and business finances, skip required formalities, or leave the company deliberately undercapitalized.

Whether you need one depends on exposure rather than revenue. A freelance writer with no employees, no premises, and no physical product carries modest liability risk and may be adequately served by a sole proprietorship plus a good insurance policy. A contractor working on other people's property, anyone with employees, anyone signing substantial contracts, and anyone with meaningful personal assets to lose has a much stronger case. Multi-owner businesses should form an entity regardless, because the alternative is a general partnership in which each partner is personally liable for what the others do.
