A sole proprietorship is a business that is owned by one person and sometimes his or her spouse and that isn’t registered with the state as a corporation or a limited liability company (LLC).
Sole proprietorship are so easy to set up and maintain that you may already own one without knowing it. For instance, if you are a freelance photographer or writer, a crafts person who takes jobs on a contract basis, a salesperson who receives only commissions or an independent contractor who isn’t on an employer’s regular payroll, you are automatically a sole proprietor.
However, even though a sole proprietorship is the simplest of business structures, you shouldn’t fall asleep at the wheel. You may have to comply with local registration, license or permit laws to make your business legitimate. And you should look sharp when it comes to tending your business, because you are personally responsible for paying both income taxes and business debts.
