Sole Proprietorship in the U.S.

By Cindy Hill

A sole proprietor is an individual who owns an unincorporated business. There are nearly 23 million sole proprietorships, not counting single-owner farm businesses, in the United States, and many of these engage employees in addition to their sole proprietor owners. Sole proprietorships are subject to state laws regarding registration and licensing, which are similar but vary from state to state.


Every state has its own code of business laws authorizing the formation and management of business entities. All states allow individuals to conduct business activities as a sole proprietor without forming an independent legal entity. The simplicity of forming a sole proprietorship is one of its chief attractions to many entrepreneurs. Some states require a sole proprietorship to obtain a statewide business license. In other states, business licensing is conducted by municipal agencies. Local licensing requirements may vary depending on the nature of the sole proprietorship business and its location.

Name Registration

Sole proprietorships in all states may operate under an assumed or fictitious business name, referred to as a "doing business as," or DBA, name. In some states, this name must be registered with a state or local agency, but no registration is necessary in other states. A primary purpose of registering a DBA is to notify the public of the contact information for the individual who is responsible for the business activity. Registering a DBA does not create a separate business entity. Sole proprietors usually continue to hold bank accounts and sign checks and contracts in their own name, even if they operate their business under a DBA.

The income from a sole proprietorship business is taxed as personal income to its owner. The sole proprietor does not need to file separate income tax returns for the business, but rather reports her income and business expenses on Schedule C, the business profit and loss attachment to her Form 1040 personal income tax return. If your sole proprietorship will have employees, you will need to obtain a federal Employer Identification Number and may need to file employer tax returns, including reports on income tax, Social Security and Medicare withholding, and unemployment tax.

Debts and Liabilities

When you operate as a sole proprietor, you are personally liable for the business's debts. If those business debts become overwhelming, sole proprietorships cannot file for business bankruptcy under federal law because the business is not an independent entity. Owners who want to discharge business debt must file personal bankruptcy. The potential for unlimited personal liability for losses incurred or judgments rendered against the sole proprietorship are among the disadvantages of operating a sole proprietorship.

Sole Proprietorship & Investment Accounts

The sole proprietorship is a very common form of small business, and beyond running their underlying business, sole proprietors are free to make investments and hold assets in investment accounts. These accounts can be used to augment savings for the business, to speculate on specific investment opportunities or to offset financial risks encountered in the sole proprietorship's business operations.

Can a Sole Proprietorship Have Employees?

A sole proprietorship is an unincorporated business owned by a single individual. The sole proprietor and business are considered one single entity under the law, unlike a corporation or partnership.
