A sole proprietorship is the simplest and most common form of business structure for an individual business owner. It is an unincorporated business owned and operated by one person.
Unlike a corporation or limited liability company, a sole proprietorship is not a separate legal entity from its owner. The business and the individual owner are generally treated as the same legal person. This means the owner is personally responsible for the debts, obligations, contracts, and liabilities of the business.
A sole proprietorship may be appropriate for very small businesses, independent contractors, consultants, freelancers, and individuals starting a business on their own. However, because there is no separate legal entity, the owner typically does not receive limited liability protection.
Name Registration / DBA
If an individual conducts business using their own personal legal name, a separate business name filing may not be required. However, if the individual wants to operate under a business name that is different from their personal legal name, the individual may need to register an assumed name, trade name, fictitious business name, or “DBA,” depending on the state or local jurisdiction.
For example, if John Smith operates as John Smith, a DBA filing may not be needed. However, if John Smith operates as Smith Consulting Services, he may need to register that business name with the appropriate state, county, city, or town office.
DBA terminology and filing requirements vary by jurisdiction. Depending on the location, the filing may be called:
- Assumed Name;
- Trade Name;
- Fictitious Business Name;
- Doing Business As;
- Business Certificate; or
- Certificate of Conducting Business Under an Assumed Name.
A DBA does not create a separate legal entity and does not provide liability protection. It simply allows the owner to conduct business under a name other than the owner’s personal legal name.
Common Characteristics of a Sole Proprietorship
A sole proprietorship generally has the following characteristics:
- Owned by one individual;
- Not a separate legal entity from the owner;
- Generally easy to start and operate;
- Owner typically reports business income and expenses on the owner’s personal tax return;
- Owner has full control over management and business decisions;
- Owner is generally personally responsible for business debts and liabilities;
- May require business licenses, permits, tax registrations, or local filings depending on the business activity and location; and
- May require a DBA, trade name, or assumed name filing if operating under a business name.
Formation and Compliance Considerations
A sole proprietorship is generally not formed by filing entity formation documents with the state in the same way as a corporation or LLC. However, the owner may still need to complete other filings or registrations before conducting business.
These may include:
- DBA, assumed name, trade name, or fictitious name registration;
- Business license or permit applications;
- Sales tax registration;
- Employer tax registrations, if hiring employees;
- Professional or occupational licenses, if applicable;
- Local business certificates or registrations; and
- EIN application, if required or desired.
Because requirements vary by state, county, city, and business activity, sole proprietors should confirm all applicable registration and licensing requirements before beginning operations.
