Introduction
An Idaho DBA, known as an Assumed Business Name (ABN), is filed once with the Secretary of State and then stays in effect until you cancel it, and it is the public registration that lets a person or business use a name different from the owner's legal name; it creates no separate legal entity. Unlike states that file at the county level, Idaho uses one statewide registration. Before you begin transacting business under an assumed name, you deliver a Certificate of Assumed Business Name to the Idaho Secretary of State, and a separate certificate is filed for each assumed name you use (Idaho Code 30-21-805). The base filing fee is $25, and a paper certificate that you mail in adds a $20 manual processing fee, so filing online with the Secretary of State is the lower-cost option. Idaho does not require you to publish notice of the assumed name in a newspaper. Filing an ABN does not create a corporation or an LLC, does not shield the owner from liability, and does not give a trademark or an exclusive right to the name. An Idaho Certificate of Assumed Business Name does not expire on a fixed term; it is in effect from the date it is filed until you cancel it by filing a certificate of cancellation with the Secretary of State (Idaho Code 30-21-807 and 30-21-809). DocDraft builds your Idaho assumed business name certificate from your facts, with attorney review available before you file.

Frequently Asked Questions
In Idaho a DBA is an Assumed Business Name (ABN), a public filing that lets a person or company do business under a name different from the owner's legal name. You register it by delivering a Certificate of Assumed Business Name to the Idaho Secretary of State before you begin transacting business (Idaho Code 30-21-805). It connects the name to you on the statewide public record. It does not create a separate legal entity, protect the name, or limit your liability.
In Idaho a DBA (assumed business name) is only a name registration you file with the Secretary of State; it creates no new entity and gives no liability protection. An Idaho LLC is a separate legal entity you form by filing a Certificate of Organization with the Secretary of State, and it shields the owners' personal assets. You can have both, since an existing LLC can file an assumed business name to run a brand under another name. Choose based on whether you need liability protection or just a name.
You file a Certificate of Assumed Business Name statewide with the Idaho Secretary of State, not with a county (Idaho Code 30-21-805). The base filing fee is $25.

Confirm the current fee with the Secretary of State before you file, since fees can change.
No. Idaho does not require you to publish notice of an assumed business name in a newspaper, and there is no affidavit of publication to file afterward. Idaho Code Title 30 chapter 21 part 8, which governs assumed business names, contains no publication step. Once the Secretary of State files your Certificate of Assumed Business Name, your registration is complete without any newspaper notice.
An Idaho Certificate of Assumed Business Name does not expire on a fixed term. Idaho Code 30-21-807 says the certificate is in effect upon filing until it is canceled. There is no five-year or ten-year renewal to track. When you stop using the name, you cancel it by filing a certificate of cancellation with the Secretary of State (Idaho Code 30-21-809). If an owner, address, or the name changes, you update the filing with the Secretary of State.
You need an Idaho Certificate of Assumed Business Name when you intend to transact business under a name that is different from your own legal name or, for a company, different from its registered legal name (Idaho Code 30-21-805). You must file before you begin transacting business under that name, and you file a separate certificate for each assumed name you use. A sole proprietor using only their own legal name generally does not need one.
No. An Idaho Certificate of Assumed Business Name is a public record connecting a name to the person using it, but it gives no ownership of or exclusive right to the name, so another business could use a similar name. It also creates no separate legal entity, so a sole proprietor filing an ABN remains personally liable for the business. For exclusive name rights you would seek a trademark, and for liability protection you would form an LLC or corporation.
Yes. An Idaho Certificate of Assumed Business Name lists each person or entity that owns the business and will use the name. For a general partnership, every partner is listed as a registrant. The certificate is filed statewide with the Secretary of State, and all listed registrants are recorded together on the one certificate for the assumed business name. A separate certificate is still filed for each different assumed name the owners use.
