A limited liability company (LLC) is a business entity formed by filing with a state. It generally keeps the company's debts and legal obligations separate from its owners' personal assets, but it doesn't cover debts you personally guarantee, and it doesn't replace insurance.
Also called: Limited liability company
An LLC is a legal person separate from you. When it signs a contract, takes on a debt or gets sued, the claim is generally against the company and what it owns: the bank account, the trucks, the equipment and the money customers owe it. Your house and personal savings are generally out of reach. A sole proprietor has no such line, because the business's debts are the owner's debts.
You form an LLC by filing with your state's business filing office and paying the state's filing fee. Your state may also require a yearly or periodic report and fee to keep the LLC in good standing, so check before you file and put the due date on your calendar.
The LLC decides whose assets a claim can reach. Insurance decides who pays it. Without coverage, a claim against the LLC goes after everything the business owns, and a big enough one can end the business even if your personal assets stay protected.
Example: A helper leaves a hose across a customer's walkway, a guest trips, and the guest's lawyer demands $50,000. If general liability insurance covers the claim, the insurer handles it up to the policy limit. Without coverage, the claim is the LLC's to pay, and its $8,000 bank balance, its $20,000 truck and its equipment are what's at stake. If the owner personally guaranteed the truck loan, that loan still has to be paid even if the business folds. The numbers are made up for illustration.
Injuries to your own employees are a separate matter, handled through workers' compensation insurance under your state's rules.
An LLC is a legal structure under state law; how it's taxed is a separate question. By default, the IRS treats a single-member LLC as a disregarded entity, not separate from its owner for income tax, and an LLC with two or more members as a partnership. Either can file Form 8832 to elect to be taxed as a corporation instead 1. Those choices change what you file and can change what you pay, so settle them with a CPA before your first return. The EIN and Schedule C pages cover two federal basics, and if the LLC will work under another name, see DBA.
Rules and figures change, and many requirements vary by state and city. Check the current version of each source and your local authority before acting, and talk to a licensed professional about your specific situation.
