How to Start an LLC in Oregon (Step-by-Step Guide)

Forming an LLC in Oregon requires filing Articles of Organization with the Oregon Secretary of State and paying a $100 filing fee. The process takes about 2-3 business days for online filings. Oregon stands out for having no sales tax — making it an attractive state for retail and e-commerce businesses.

Oregon’s LLC formation process is straightforward, with a reasonable filing fee and fast online processing. However, the state’s income tax rates are among the higher end nationally, and the $100 annual report fee adds to ongoing costs. Here’s everything you need to know to form your Oregon LLC.

Follow these steps to start your Oregon LLC in 2026.

How to Start an LLC in Oregon (6 Steps)

Step 1: Name Your Oregon LLC

Your LLC name must be distinguishable from other business names registered in Oregon. The name must include “Limited Liability Company,” “LLC,” “L.L.C.,” or an abbreviation of these terms. Your business name appears on all official documents and public records, so choose something that represents your brand well.

Search the Oregon Secretary of State’s business name database to check availability. You can reserve a name for 120 days by filing a Name Reservation ($100 fee). Oregon also offers a free Business Name Availability Check through the same portal.

Oregon naming rules:

• Must be distinguishable from any existing business entity registered in Oregon
• Cannot include words suggesting it’s a bank, insurance company, or government entity without proper authorization
• Must include an LLC designator (“Limited Liability Company,” “LLC,” or “L.L.C.”)
• Cannot contain language implying a purpose the LLC is not authorized to pursue

Tips for choosing your LLC name:

• Use Oregon’s free name availability check before filing
• Check domain name availability for your business website
• Search the USPTO trademark database to avoid conflicts
• Choose a name that’s easy to spell, pronounce, and remember

Step 2: Choose a Registered Agent

Oregon requires every LLC to have a registered agent with a physical street address in Oregon. The registered agent accepts legal documents, government notices, and official correspondence on behalf of your LLC. Oregon law requires the agent to be available during standard business hours (Monday-Friday, 9 a.m. to 5 p.m.).

You have three options:

Option 1: Be your own registered agent. If you’re an Oregon resident with a physical street address, you can serve as your own agent. This is free but puts your personal address on public record and requires constant availability during business hours.

Option 2: Appoint a trusted individual. Any Oregon resident with a physical address can serve as your registered agent.

Option 3: Use a professional service. Our top recommendation is Northwest Registered Agent ($39/year), which is actually based in Oregon and also handles LLC formation for $39 + the $100 state fee. Professional services keep your address private and ensure reliable document handling.

Step 3: File Your Articles of Organization

File Articles of Organization with the Oregon Secretary of State. You can file online through the Oregon Business Registry or by mail. Online filing is recommended for faster processing and immediate confirmation.

Filing details:

• Filing fee: $100
• Online filing: Oregon Business Registry at sos.oregon.gov (recommended — faster processing)
• Processing time: 2-3 business days (online), 4-6 business days (mail)
• Payment: Credit or debit card for online filings

Information required on the Articles of Organization:

• LLC name
• Principal office address
• Registered agent name and Oregon street address
• Mailing address (if different from principal office)
• Name and address of each organizer
• Whether the LLC is member-managed or manager-managed
• Duration (perpetual is standard)

Member-managed vs. manager-managed: In a member-managed LLC, all owners share in running the business. In a manager-managed LLC, designated managers handle daily operations while other members are passive investors. Most small LLCs choose member-managed.

Step 4: Create an Operating Agreement

Oregon doesn’t legally require an operating agreement, but having one is strongly recommended. This internal document defines how your LLC operates and protects all members’ interests.

Key provisions to include:

• Ownership percentages and capital contributions
• Profit and loss distribution among members
• Voting rights and decision-making procedures
• Rules for admitting new members or handling departures
• What happens if a member dies or becomes incapacitated
• Management authority and responsibilities
• Dissolution procedures

Even single-member LLCs should have an operating agreement. It reinforces your liability protection by demonstrating that the LLC is a separate entity from you. Most banks also require one to open a business account.

Step 5: Get an EIN

Apply for an Employer Identification Number (EIN) through the IRS website. It’s free and takes about 15 minutes online. Your EIN serves as your business’s tax identification number, and you’ll need it for opening a bank account, hiring employees, and filing taxes.

Get your EIN even if you don’t plan to hire employees. Banks require one for business accounts, and using an EIN instead of your Social Security number helps protect your personal identity.

Step 6: File Your Annual Report

Oregon LLCs must file an annual report with the Secretary of State each year. The report is due during the anniversary month of your LLC’s formation, and the filing fee is $100. All annual reports must be filed online.

Annual report details:

• Due during the anniversary month of your LLC’s formation
• Filing fee: $100
• Must be filed online through the Oregon Business Registry (no mail option)
• You can file up to 45 days before your due date
• Online reports are processed within 1-2 business hours during business hours
• Failure to file will result in administrative dissolution

The annual report is a simple update confirming your LLC’s registered agent, principal office address, and other basic details. Filing early is recommended — Oregon allows submission up to 45 days before your due date, so set a reminder to avoid missing the deadline.

Oregon LLC Costs

Total first-year cost: $100-$499 (depending on whether you use a registered agent service). Oregon’s $100 annual report fee is higher than the national average, but the state’s lack of sales tax can offset this for many businesses. See our complete guide to LLC costs by state.

Ongoing annual costs: After formation, you’ll pay $100/year for the annual report plus any registered agent fees. If you serve as your own registered agent, your only recurring cost is $100/year.

Oregon LLC Taxes

Oregon has no sales tax — it’s one of only five states that doesn’t charge sales tax at all. This is a major advantage for retail businesses and e-commerce companies. However, Oregon does have state income tax rates on the higher side.

• State income tax: 4.75% to 9.9% (graduated rates based on income — among the higher rates nationally)
• Sales tax: None — Oregon has no state or local sales tax
• Corporate excise tax: 6.6% on the first $1 million of taxable income, 7.6% on income above $1 million (only if your LLC elects corporate taxation); minimum tax of $150
• Self-employment tax: 15.3% federal (12.4% Social Security + 2.9% Medicare)
• Federal income tax: Standard pass-through taxation — profits pass to members’ personal returns

How Oregon LLC taxation works: By default, Oregon LLCs use pass-through taxation. The LLC doesn’t pay income tax at the entity level. Profits and losses flow through to each member’s personal tax return. Single-member LLCs report on Schedule C; multi-member LLCs file Form 1065 and issue K-1 forms.

Portland-area taxes: If your LLC operates in the Portland metropolitan area, be aware of additional local taxes. Multnomah County imposes a Preschool for All personal income tax (1.5% to 3% on income above certain thresholds), and the Metro Supportive Housing Services tax (1% on income above certain thresholds). These apply to individuals, including LLC members who live or work in these areas.

Corporate Activity Tax (CAT): Oregon imposes a Corporate Activity Tax on businesses with more than $1 million in Oregon commercial activity. The CAT is $250 plus 0.57% of Oregon commercial activity exceeding $1 million. Most small LLCs will fall below this threshold.

Annual Requirements for Oregon LLCs
