Sole Proprietorship

Last updated: July 2026

A sole proprietorship is an unincorporated business owned and run by one person, with no legal separation between the owner and the business, which means the owner is personally responsible for the business's debts and lawsuits. The Allen Thomas Group helps sole proprietors close that personal liability gap with general liability and, where relevant, professional liability coverage, since there's no corporate structure standing between a claim and the owner's personal assets.

How It Differs From an LLC or Corporation

A sole proprietorship requires no separate formation filing in most cases, the business simply exists as soon as the owner starts operating. Income and losses flow directly onto the owner's personal tax return (typically Schedule C), and there is no liability shield between business obligations and personal ones.

Why Insurance Matters More, Not Less

Because there's no corporate structure absorbing a lawsuit, a claim against the business is effectively a claim against the owner's house, savings, and other personal property.

Common Coverage Gaps

A lot of sole proprietors operate without any general liability policy because they assume being small or working solo makes them low risk. A single slip-and-fall at a client's site or a dissatisfied customer's lawsuit can wipe out personal savings just as easily as it could a larger company's balance sheet.
