How an LLC Files

An LLC registers an assumed name with the Secretary of State Corporation Division.

You can file online.

Oregon registers assumed business names by county inside one state filing, so the same name can be registered by different businesses in different counties.

Cost and Renewal

The filing fee is $50.00.

The registration has a 2-year term.

The registration stays in effect until it is canceled, but it must be renewed every two years. The Secretary of State may cancel a registration that is not renewed.

Renewal costs $50.00.

Publication

We found no publication step for an LLC's assumed name filing in Oregon.

Does it protect the name?

Registering does not give the LLC ownership of, or an exclusive right to, the name.

If you skip it

A business trading under an unregistered assumed name cannot bring a lawsuit for the business until it registers, and a violation carries a civil penalty of up to $100. A person who sues it over that business can recover $500 or the actual cost of finding its real name, whichever is greater.

Sole proprietors

Oregon requires a sole proprietor whose business name is not their full name to register an assumed name. A sole proprietor or general partnership must register unless the business name includes each owner's last name together with a first name or initials. A name with words that suggest other owners, such as Company or and Associates, must be registered.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state's filing office publishes about registering a business name, with the sources this page cites. A filing here does not register a federal trademark, and fees and forms change between our reviews. Confirm with the office named on this page before you file.
