How to Start an LLC in Oregon
How to Start an LLC in Oregon
Forming an LLC in Oregon means filing Articles of Organization with the Oregon Secretary of State, Corporation Division, paying a $100 filing fee, and keeping up with a $100 annual report every year after that. That's the short version. The longer version, including where the paperwork trips people up, is below.
This guide walks through the actual steps to form an LLC in Oregon: picking a compliant name, lining up a registered agent, filing online through the Oregon Business Registry, and handling the tax registrations that come after formation. If you want the exact numbers before you start, you're in the right place.
What You'll Need Before You File
- An LLC name that includes "Limited Liability Company," "LLC," or "L.L.C." and is distinguishable from other active Oregon entities.
- A registered agent with a physical Oregon street address (no P.O. boxes, mail-forwarding services, or virtual offices).
- $100 for the Articles of Organization filing fee.
- An Oregon Business Registry (OBR) account to file online at secure.sos.state.or.us/cbrmanager.
- Basic organizer information: the name and address of the person filing, and the LLC's principal place of business.
- An operating agreement (not filed with the state, but you'll want one).
- An EIN from the IRS once your LLC is approved.
Step-by-Step: Forming Your Oregon LLC
1. Choose and Check Your LLC Name
Your name needs the required designator (LLC, L.L.C., or the full "Limited Liability Company") and it has to be distinguishable from every other active entity on file with Oregon. Note what doesn't count as distinguishable: differences in punctuation, spacing, capitalization, pluralization, or filler words like "a," "the," or "and." "Cascade Coffee LLC" and "Cascade Coffee, L.L.C." are treated as the same name.
Search existing names using the Secretary of State's business name search at egov.sos.state.or.us/br/pkg_web_name_srch_inq.login before you get attached to a name. The final call on distinguishability is made by Corporation Division staff when you file, not by the search tool, so treat a clear search result as a good sign, not a guarantee.
Optional: Reserve the name. If you're not ready to file Articles of Organization yet but want to lock in a name, you can reserve it for 120 days for a $100 fee using the form at sos.oregon.gov's name reservation form. Most people filing right away skip this step since it's an extra $100 for something the Articles filing accomplishes anyway.
2. Appoint a Registered Agent
Every Oregon LLC has to continuously maintain a registered agent and a registered office inside the state. The agent can be an Oregon resident whose business office matches the registered office, or an authorized business entity with a business office at that same address. The registered office must be a physical street address in Oregon where someone can be personally served with legal papers. A P.O. box, mail-forwarding business, commercial mail receiving agency, or virtual office address will not work.
You can serve as your own registered agent if you have an Oregon street address and are reliably present there during business hours. Plenty of owners use a commercial registered agent service instead, mainly for privacy (your home address won't sit on a public filing) and to avoid missing a legal notice while traveling. If you ever need to change your registered agent or registered office address later, that update costs $0 to file.
3. File the Articles of Organization
This is the actual formation step. File "Articles of Organization - Limited Liability Company" with the Oregon Secretary of State, Corporation Division, either online through the Oregon Business Registry at secure.sos.state.or.us/cbrmanager or by mailing in the paper form. The filing fee is $100 either way.
Filing online is the faster route: Oregon estimates 1 to 3 business days for online filings, with review generally starting within one business day of submission. There is no published expedited processing tier or rush fee in Oregon's Business Registry Fee Schedule, so online filing is effectively the fastest option available, not a slower default you can pay to skip.
You'll need to provide the LLC's name, its principal office address, the registered agent's name and Oregon address, and the name and address of whoever is filing (the organizer). Oregon doesn't require you to name members or managers in the Articles itself.
4. Draft an Operating Agreement
Oregon doesn't require you to file an operating agreement with the state, and it's not a mandatory legal requirement to have one at all. That said, skipping it is a common mistake. Without a written agreement, your LLC defaults to Oregon's statutory rules for how profits, losses, and decision-making authority get handled, which may not match what you and your co-owners actually intend.
A basic operating agreement should spell out ownership percentages, how profits and losses are allocated, who can bind the LLC to contracts, how new members are admitted, and what happens if a member wants out. If you have more than one member, or any outside investment, this is worth getting right, and worth a consultation with a business attorney if the ownership structure is complex.
5. Get an EIN From the IRS
Once your Articles of Organization are approved, apply for an Employer Identification Number (EIN) from the IRS. It's free directly through the IRS website, and you'll need it to open a business bank account, hire employees, and file federal taxes. Be wary of third-party sites that charge a fee for something the IRS provides at no cost.
6. Register With the Oregon Department of Revenue
Oregon has no state sales tax, so there's no sales tax permit to register for. But you still have state tax obligations to sort out. By default, a single-member LLC is a disregarded entity and a multi-member LLC is taxed as a partnership for both federal and Oregon purposes, meaning profits pass through to the members' personal Oregon income tax returns. Oregon's personal income tax is progressive, with 2025 rates of 4.75%, 6.75%, 8.75%, and a top rate of 9.9% (the 8.75% bracket runs from $50,000 to $125,000 of taxable income for single and married-filing-separately filers, with 9.9% above that).
If your LLC elects to be taxed as a corporation for federal purposes, Oregon follows that election and taxes it under the corporation excise tax instead.
Separately, watch for Oregon's Corporate Activity Tax (CAT). Any business entity, including an LLC, with Oregon commercial activity of $750,000 or more in a year must register for the CAT, and the tax itself is $250 plus 0.57% of taxable Oregon commercial activity above $1 million. Most new, small LLCs won't hit this threshold right away, but it's worth knowing before you scale. Check current requirements at the Oregon Department of Revenue's business pages.
7. Check for Licenses and Local Permits
Oregon does not issue a general statewide business license. The Secretary of State treats your business registration itself as covering that base. But plenty of specific occupations and activities still need a state, city, or county license, permit, or certification, everything from contractors to food service to professional services like cosmetology or accounting.
Search the Business Xpress License Directory at apps.oregon.gov/sos/licensedirectory for state-level requirements, and check directly with the city and county where you'll operate for local business licenses and zoning rules. This step gets skipped constantly, and it's the one most likely to cause a headache down the road if a city or county fines you for operating without a required local permit.
8. Register a DBA If You'll Operate Under a Different Name
If your LLC will do business under a name different from its legal name on file (an "assumed business name" or DBA), register it with the Secretary of State, Corporation Division, not at the county level. The fee is $50 for a new registration, valid for two years, with a $50 renewal every two years after that. The form is available at sos.oregon.gov's assumed business name form.
9. Open a Business Bank Account
Once you have your approved Articles of Organization and your EIN, open a dedicated business checking account. Mixing personal and business funds is one of the fastest ways to undermine the liability protection an LLC is supposed to give you; if a court finds your finances are commingled, it can "pierce the corporate veil" and expose your personal assets in a lawsuit against the business.
10. File Your Annual Report Every Year
Oregon LLCs must file an Annual Report (technically a renewal) every year on the anniversary date of the original filing. The fee is $100. The Corporation Division mails a renewal notice roughly 45 days ahead of the due date, but don't rely on the mail arriving; missing this filing is how otherwise healthy LLCs get administratively dissolved. Mark the anniversary date on your own calendar as a backup.
Common Mistakes to Avoid
- Using a P.O. box as your registered office. Oregon requires a physical street address where someone can be served in person. A mail-forwarding address or virtual office won't pass.
- Assuming a name search result is final. The name search tool is a good screening step, but Corporation Division staff make the final distinguishability call at the time you file. Have a backup name ready.
- Skipping the operating agreement. Even for a single-member LLC, a short written agreement helps establish that the LLC is a separate entity from you personally, which matters if liability protection is ever tested.
- Forgetting the annual report. The $100 renewal is easy to overlook, especially in year two or three once the initial excitement of filing has worn off.
- Assuming Oregon issues a general business license. It doesn't. Confirm what your specific industry, city, and county actually require instead of assuming your LLC registration covers you.
- Not budgeting for the Corporate Activity Tax if you're scaling fast. The $750,000 commercial activity registration threshold can arrive sooner than expected for a growing business.
What to Expect After Filing
Filing online through the Oregon Business Registry is generally expected to move fairly quickly, with review typically starting within about a business day and most filings appearing to process within roughly 1 to 3 business days, though actual turnaround can vary and is not guaranteed by the state. Once approved, you should receive confirmation that your LLC is on file, at which point you can move on to getting your EIN and opening a bank account.
Keep in mind that formation itself is just the starting line. An LLC in good standing depends on staying current with the $100 annual report, maintaining a valid registered agent and office at all times, and keeping up with any state, city, or county licensing that applies to your specific business.
