A complete 2026 guide to starting your Oregon limited liability company, from name search to EIN registration.
A limited liability company (LLC) is one of the most popular business structures in Oregon for good reason. It provides personal liability protection, separating your personal assets from business debts and legal obligations. Oregon is particularly attractive for LLC formation because the state does not impose a separate franchise tax or LLC-specific tax. Your business income simply flows through to your personal income tax return.
Oregon's filing fees are moderate at $100 for initial formation and $100 for the annual report. Compared to states like California (which charges an $800 annual franchise tax) or Massachusetts ($500 annual fee), Oregon is significantly more affordable for small business owners. The state also offers online filing, making the process fast and convenient.
Additionally, Oregon has no state sales tax, which simplifies operations for retail and e-commerce businesses. However, be aware that Oregon's income tax rates are among the highest in the nation, with a top rate of 9.9%. Use the Oregon Tax Calculator to estimate your tax liability as an LLC owner.
Your LLC name must be distinguishable from any existing business entity registered with the Oregon Secretary of State. Oregon law requires that your name include "Limited Liability Company," "LLC," or "L.L.C." as a designator.
Before settling on a name, search the Oregon Secretary of State's business name database to confirm availability. You can reserve a name for 120 days by filing an Application for Name Reservation with a $100 fee, though this step is optional if you plan to file immediately.
Consider whether you also want to secure a matching domain name and social media handles. A consistent brand identity across platforms will help establish credibility with customers and partners from the start.
Every Oregon LLC must designate a registered agent with a physical street address in Oregon. The registered agent receives legal documents, tax notices, and official correspondence on behalf of your LLC. You can serve as your own registered agent, but many business owners prefer to use a professional service for privacy and reliability.
A registered agent must be available at the listed address during normal business hours. Missing a legal notice because you were unavailable could result in default judgments or administrative dissolution of your LLC.

Form My Oregon LLCFile your Articles of Organization with the Oregon Secretary of State, Business Division. You can file online through the state's Central Business Registry or submit a paper form by mail. The filing fee is $100.
Your Articles of Organization must include: the LLC name, the registered agent's name and address, the mailing address of the LLC, the name and address of at least one authorized representative, and whether the LLC will be member-managed or manager-managed.
Online filings are typically processed within 1-2 business days. Paper filings may take 2-3 weeks. Expedited processing is available for an additional fee if you need faster turnaround.
While Oregon does not legally require an operating agreement, having one is strongly recommended, especially for multi-member LLCs. An operating agreement defines the ownership structure, profit distribution, management responsibilities, and procedures for adding or removing members.
Even single-member LLCs benefit from an operating agreement because it reinforces the legal separation between you and your business, which is essential for maintaining liability protection. Banks and financial institutions may also require an operating agreement when opening a business bank account.
An Employer Identification Number (EIN) is a federal tax ID for your business. You need an EIN to open a business bank account, hire employees, and file federal taxes. Applying is free and can be done online at IRS.gov. The process takes about 10 minutes, and you receive your EIN immediately upon completion.
Single-member LLCs without employees can technically use your Social Security number, but obtaining an EIN is recommended for privacy and professional credibility. It also makes it easier to establish business credit separate from your personal credit history.
Keeping your personal and business finances separate is critical for maintaining your LLC's liability protection. Open a dedicated business checking account using your EIN and Articles of Organization. Most Oregon banks and credit unions offer business accounts with low or no monthly fees for small businesses.
Oregon LLCs must file an annual report with the Secretary of State each year on the anniversary of your formation date. The annual report fee is $100. Failure to file will result in administrative dissolution of your LLC.
You may also need local business licenses depending on your city and industry. Portland, for example, requires a city business license for most businesses operating within city limits. Check with your local city hall for specific requirements.
Finally, understand your tax obligations. Oregon LLC income is reported on your personal state income tax return. Use the Oregon Income Tax Calculator to estimate your annual tax liability based on your projected business income.
