Oregon DBA Filing: Assumed Business Name Cost (2026)
In Oregon, a DBA is called an Assumed Business Name (ABN). You register it with the Oregon Secretary of State, Corporation Division, for a $50 processing fee, and the registration lasts two years before you must renew it (also $50). Filing is statewide under ORS Chapter 648, so one registration covers business anywhere in Oregon.

What an Oregon DBA (Assumed Business Name) Is
A “DBA” - short for “doing business as” - is any business name that differs from the legal name of the person or entity using it. Oregon does not use the phrase “DBA” in its statutes. Instead, Oregon calls it an Assumed Business Name, or ABN. The rules are set out in ORS Chapter 648, the Assumed Business Names statute, and the registration is handled centrally by the Oregon Secretary of State, Corporation Division.
You need an Oregon ABN whenever you carry on business under a name that is not your own legal name (for a sole proprietor) or not the exact registered name of your entity (for an LLC or corporation). For a general primer on how assumed names work nationwide, see what is a DBA. If your goal is actually to create a business with liability protection, an ABN is not the tool - you would form a limited liability company instead.
Who Needs to Register an Assumed Business Name in Oregon
Oregon law requires registration by anyone - an individual, partnership, LLC, or corporation - who carries on business under an assumed name. Common examples: a sole proprietor named Maria Lopez operating as “Rose City Bakes”; an LLC named “Cascade Holdings LLC” running a storefront branded “Cascade Coffee.” In each case the public-facing name differs from the legal name, so an ABN is required.
If a sole proprietor operates strictly under their own full legal name, no ABN is needed. Likewise, an LLC that does business under its exact registered name does not need one. The moment you brand under a different name - on signage, invoices, bank accounts, or advertising - the registration requirement is triggered. Registering also lets you open a bank account and accept payments in the trade name.
How to File an Oregon Assumed Business Name
Registering an Oregon ABN takes a single filing with the Secretary of State. The process is the same whether you are a sole proprietor or an existing entity adding a brand name.
- Check the name. Search the Oregon Business Registry business name database to confirm your assumed name is available and distinguishable. Confirm it does not infringe a federal trademark before you build a brand around it.
- Complete the Assumed Business Name - New Registration. Provide the assumed name, a description of the business activity, the name and address of each authorized registrant, and the Oregon counties (or “all”) where you will use the name.
- File and pay the $50 fee. Submit online through the Oregon Business Registry for the fastest processing, or mail the form to the Corporation Division in Salem with payment.
- Record your renewal date. The registration is good for two years. Calendar the expiration so you renew on time and keep the name active.
Because Oregon registration is statewide, you do not file separately in each county the way some other states require. That single-filing convenience is one reason the Oregon ABN system is simpler than county-by-county DBA systems elsewhere.
Oregon DBA Fees and Renewal (2026)
The Oregon ABN fee structure is simple. Amounts are set by the state and listed on the Oregon Secretary of State Business Registry Fee Schedule.
| Action | Fee (2026) | Term | Agency |
|---|---|---|---|
| New Assumed Business Name registration | $50 | 2 years | Secretary of State |
| Assumed Business Name renewal | $50 | 2 years | Secretary of State |
| Amendment / change of registrant | See fee schedule | - | Secretary of State |
| Federal EIN (if you want a separate tax ID) | $0 (free) | - | IRS |
An ABN does not carry its own annual report the way an LLC does. If your business is an LLC, the LLC still files its own Oregon annual report separately from any assumed name. Compare full entity costs on our Oregon LLC cost page.
DBA vs. LLC in Oregon
An Assumed Business Name and a limited liability company solve different problems. An ABN only lets you operate under a chosen name; it creates no separate legal entity, provides no liability protection, and does not change how you are taxed. A sole proprietor with an ABN is still personally liable for business debts and lawsuits.
An LLC, by contrast, is a separate legal entity that shields the owners' personal assets and is created by filing Articles of Organization for a $100 fee. Many Oregon owners do both: they form an LLC for the liability shield, then register an ABN so the LLC can operate under one or more brand names. If you are weighing the two, read sole proprietorship vs. LLC.
EIN, Taxes, and Bank Accounts
Registering an ABN does not, by itself, create a tax obligation or a new tax ID. A sole proprietor generally reports income on Schedule C using their Social Security number, though many choose to get a free Employer Identification Number (EIN) from the IRS to keep business and personal finances separate and to open a business bank account under the trade name.
Oregon has no statewide general sales tax, so most ABN holders do not collect sales tax, though local and industry-specific taxes can apply. If you hire employees or owe state business taxes, register with the Oregon Department of Revenue. Check any city or county licensing requirements through our Oregon business license guide.
Keep in mind that an ABN does not change your underlying tax status. A sole proprietor operating under an assumed name is still taxed as a sole proprietor, and an LLC that adds an assumed name is still taxed according to its federal classification - disregarded entity, partnership, or a corporation if it made an S-corporation election. The assumed name is purely cosmetic for tax purposes: it lets you invoice, bank, and advertise under a brand, but the IRS and the Oregon Department of Revenue look through to the person or entity behind it. If you want the assumed name attached to a liability shield and a distinct tax profile, pair it with a properly formed LLC rather than treating the ABN as a substitute.
An ABN Is Not a Trademark
Registering an Assumed Business Name secures the name on the Oregon Secretary of State's business registry, but it does not give you trademark rights. Two different tools protect two different things. An ABN registration tells the state and the public that you are using a particular name to do business in Oregon; it prevents another Oregon filer from registering an identical assumed name, but it does not stop a competitor from using a similar brand, and it carries no rights outside Oregon.
A trademark, by contrast, protects the brand associated with your goods or services and can be enforced against confusingly similar marks. If your name matters to your brand, search the federal register before you build around it and consider a federal registration through our how to trademark a business name guide. Relying on an ABN alone leaves your brand exposed. Many owners register the ABN for the operational right to use the name and separately pursue a trademark for brand protection - the two are complementary, not interchangeable. Confirming availability against both the state registry and the federal trademark database before printing signage or launching a website saves costly rebranding later.
Keeping Your Oregon ABN Active
The most common mistake with an Oregon ABN is letting it lapse. Because the registration lasts only two years, it is easy to forget. If it expires, your legal right to the name on the state record ends, and someone else could register it. Renew before the expiration date, again for $50, to keep the name protected on the Secretary of State's records.
Also update the registration if the authorized registrants or the business's information change. Keeping the ABN current, alongside any registered agent and annual-report obligations for your underlying entity, keeps your public records accurate and avoids gaps that can complicate banking or contracts.
