Sell physical products and Oregon's lack of any sales tax is a genuine edge over almost every other state. That advantage gets balanced out on the income tax side, where Oregon's rates sit near the top of the national range. Here's the practical rundown on starting a business in Oregon in 2026.
1. Which business structure fits you?
Knowing your options up front saves a paperwork headache later.
- Sole proprietorship. Free to start since there's no filing involved, though the flip side is that you and the business share one legal identity, so its debts become yours.
- Partnership. The multi-owner version of a sole proprietorship, with liability spread across partners rather than reduced.
- LLC. The default pick for small Oregon businesses, largely because it separates your personal assets from whatever the business owes or gets sued for.
- Corporation (S-corp or C-corp). Involves more paperwork and formal structure, and tends to pay off once you're bringing in investors or multiple shareholders.

LLCs and corporations register with the Oregon Secretary of State, Corporation Division, which oversees business filings across the state. Sole proprietorships and general partnerships never need to appear there.
2. Register your business
Forming an LLC
Articles of Organization, filed with the Secretary of State through the Oregon Business Registry, is what creates your LLC here. The fee is $100, and outside of a rare waiver situation, online filing is essentially the only route available.
Every Oregon LLC needs a registered agent at a physical in-state address, staffed during normal business hours. Take on the role yourself, or hand it to a commercial registered agent service.
There's no legal requirement in Oregon to have an operating agreement. Multi-member LLCs benefit from one regardless, since it lays out how the members will make decisions and split profits before any disagreement forces the question.
Sole proprietorships and DBAs
No Articles of Organization filing applies to sole proprietors. Operating under an assumed business name means a separate registration with the Secretary of State's Corporation Division, distinct from anything involved in forming an LLC.
3. Get an EIN
The IRS issues Employer Identification Numbers free of charge, and the online application generally wraps up in about 15 minutes. It's required to open a business bank account, to hire anyone, and for most business tax filings, including a single-member LLC that has no employees at all.
4. Check licenses and permits
There's no single statewide business license covering everyone in Oregon. What you actually need hinges on industry and location: regulated professions carry their own licensing requirements, and Portland requires a city business license for most businesses operating within its limits. Our guides to industry-specific licensing and home-business zoning rules cover the details.
5. Understand Oregon taxes
No state or local government in Oregon collects sales tax, a policy shared with only four other states, which makes pricing and bookkeeping noticeably simpler. The counterweight is personal income tax, which climbs progressively from 4.75% to a top rate of 9.9%, one of the higher ceilings nationwide. LLCs that elect corporate tax treatment instead pay a 6.6% excise tax on the first $1 million of taxable income, and 7.6% on anything above that.
There's also the Corporate Activity Tax to watch for, a gross-receipts tax that applies once Oregon commercial activity passes $1 million annually, at $250 plus 0.57% of the amount over that threshold. Cross $750,000 in commercial activity and you must register within 30 days regardless of whether you owe anything yet. Most small LLCs stay well under both numbers.
6. Stay compliant
Oregon LLCs owe an Annual Report to the Secretary of State every year, and the due date is the exact anniversary of your original filing date, not a fixed month or calendar deadline. It costs $100. There's no formal late fee attached, but the filing window opens 45 days ahead of your deadline, and letting it lapse gets your LLC inactivated and eventually dissolved administratively.
