How to Start an LLC in Oregon (2026): Step-by-Step Guide

Published: June 2026 · Updated for the 2026 tax year

Starting an LLC in Oregon is one of the simpler, cheaper formations in the country — $100 to file, $100 a year after that, approved in a couple of days, no newspaper notice. The catch isn't the formation; it's the tax. Oregon has no sales tax, which everyone repeats, but it pairs that with one of the highest income taxes in the US, a Corporate Activity Tax for larger businesses, and a stack of local taxes in the Portland metro. This guide walks through every step, what an Oregon LLC actually costs year by year, the honest tax trade-off, how to form one from outside the US, and the deadlines that quietly inactivate LLCs that miss them.

A note from Slava

I'm Slava, co-founder and CEO of Jupid. Before this I co-founded and scaled an AI-powered accounting platform to around $30M in revenue and more than 100,000 business users — the kind of company that ends up filing a lot of paperwork in a lot of states and watching customers trip over the same potholes again and again.

Oregon is the state where the headline is true but misleading. "No sales tax" is real, and for a product business it's worth a lot. But people read "no sales tax" as "low tax," and Oregon is not a low-tax state — it has a graduated personal income tax that tops out at 9.9% on pass-through profit, a Corporate Activity Tax that kicks in once your Oregon commercial activity passes $1 million, and if you operate in Portland you're stacking a city business tax, a county business income tax, and two metro-area income taxes on top of all that. The formation is the easy, cheap part. The tax planning is where the money is.

So this guide does the things the formation-service pages skip: it adds up the real cost over time, it's honest about the tax stack instead of stopping at "no sales tax," it spells out the non-resident path, and it hands you a dated checklist for your first 90 days so the anniversary annual report doesn't catch you. Everything here is current for 2026, with links to the official sources so you can verify before you file.

Should you actually form your LLC in Oregon?

If you live in Oregon and run your business from Oregon, you should form your LLC in Oregon. The setup is cheap and quick, and there's no reason to involve another state.

The trickier question is the one people get wrong: "Should I form in Oregon to avoid sales tax?" Usually no. Sales tax follows the buyer's location and where you have nexus, not where your LLC is registered. Forming an Oregon LLC does not make a Texas seller's Texas sales tax disappear, and if you operate from another state you'd register the Oregon LLC there as a foreign LLC, pay that state's fees, and keep a registered agent in both places — paying twice for no tax saving. The "no sales tax" advantage is real only when Oregon is actually where you do business.

Forming elsewhere makes sense in a narrower set of cases: you genuinely don't operate in Oregon, you're a non-resident with no US footprint, or you have a specific reason — outside-investor expectations, for instance — that points to Delaware. If you're a location-independent non-resident shopping for a low-cost, low-friction state, Wyoming is usually the better pick (about $100 to file, $60 a year, no income tax). Our best state to form an LLC tool walks through the trade-offs side by side.

For everyone whose business is in Oregon: Oregon it is. Here's how.

How to start an Oregon LLC, step by step

1. Choose and check your LLC name

Your name has to include "Limited Liability Company," "LLC," or "L.L.C.," and it has to be distinguishable from every other active entity on the Secretary of State's records (ORS 63.094). Search the Oregon Business Registry before you get attached to anything — the state checks availability before it files your Articles anyway. Want ideas or to test a few options at once? Our Oregon business name generator is built for that. If you need to hold a name before filing, a name reservation locks it for 120 days — but note it costs $100, the same as filing the LLC itself, so most people just file directly.

2. Appoint an Oregon registered agent

Every Oregon LLC needs a registered agent who can accept legal papers and official notices on its behalf. The agent must be an Oregon resident, or a registered-agent company authorized in Oregon, with a physical Oregon street address — a P.O. box won't do — available during normal business hours (ORS 63.111). You can serve as your own agent if you're an Oregon resident; the LLC itself cannot be its own agent. The agent's name and address are public record, which is one reason out-of-state owners and people who'd rather not publish a home address hire a commercial registered agent for roughly $100–$150 a year.

3. File the Articles of Organization

This is the step that creates your LLC. File the Articles of Organization online through the Oregon Business Registry for $100. You'll list the LLC name, the registered agent and Oregon address, the principal place of business, and whether the LLC is member-managed or manager-managed. Online filings are usually approved in about two to three business days; mail runs roughly one to two weeks. Once it's approved, download the confirmation — your bank will ask for it.

4. Write an operating agreement

Oregon doesn't legally require an operating agreement, but you should have one anyway. Your bank will ask for it, and it's part of how you keep personal and business liability separate. It sets out ownership percentages, how profits are split, who can make decisions, and what happens if a member leaves. Even a single-member LLC should have one — you keep it with your company records, not on file with the state.

5. Get your EIN from the IRS

An EIN is your LLC's federal tax ID, and you need it to open a bank account, hire anyone, and file taxes. It's free. Apply at irs.gov — if you have an SSN or ITIN, the online application takes a few minutes. If you don't (common for non-resident owners), file Form SS-4 by fax, mail, or the IRS international phone line; see the non-resident section below. Never pay a third party for the EIN itself — the number is always free from the IRS.

6. Register for Oregon taxes and any local licenses

Here's where Oregon differs from most states. There's no sales tax to register for — a genuine simplification. But pass-through profit is taxed on your personal Oregon return at rates up to 9.9%, so set up the bookkeeping to track it. If you'll have employees, register with the Oregon Employment Department for unemployment insurance and with the Oregon Department of Revenue for withholding and the statewide transit tax. If you operate in the Portland metro, check the City of Portland Revenue Division for the Business License Tax and Multnomah County Business Income Tax. And any professional or industry license you'd need as a sole proprietor — contractor, food service, cannabis, regulated services — you still need as an LLC.

7. Calendar your annual report

Every year you file a $100 annual report with the Secretary of State, due on your LLC's anniversary date — the anniversary of formation, not a fixed calendar date. There's a 45-day grace period; miss that and the state administratively dissolves (inactivates) your LLC, which freezes your ability to do business under its name. Reinstating costs a $100 fee plus $100 for each missed report. The SOS mails a reminder about 45 days out, but don't rely on it — put the anniversary on your calendar.

What an Oregon LLC really costs, year by year

Most guides quote "$100 plus $100" and stop. The fees genuinely are that cheap. The real cost of an Oregon LLC is the tax, not the filing — so here's both halves of the picture.

Year one

Every following year

The part that actually costs money: the tax stack. The fees above are the cheap part. What you'll really pay depends on profit and where you operate:

• State income tax. Oregon profit passes through to your personal return and is taxed at a graduated rate — 4.75%, 6.75%, 8.75%, and 9.9% at the top (the 9.9% bracket starts above $125,000 single / $250,000 married filing jointly). That top rate is among the highest in the country, and there's no sales-tax offset at the personal level.
• Corporate Activity Tax (CAT). This is separate from income tax and based on Oregon gross receipts. You must register once Oregon commercial activity hits $750,000, and file and pay once it tops $1 million — the tax is $250 plus 0.57% of activity above $1M, after a 35% subtraction for cost inputs or labor. Most small LLCs never owe it; a scaling one needs to watch the line.
• Portland-metro local taxes. If you do business in Portland or Multnomah County, layer on the City of Portland Business License Tax (2.6%, with an exemption under $75,000 in gross receipts for 2026), the Multnomah County Business Income Tax (2%, exempt under $100,000), and the Metro Supportive Housing Services and Multnomah County Preschool for All personal income taxes. This is why "no sales tax" rarely means "low tax" for a Portland business.

One bright spot — the PTE-E election. If your LLC is taxed as a partnership or S-corp and is profitable, Oregon's Pass-Through Entity Elective tax (9% on the first $250,000 of distributive proceeds, 9.9% above) lets owners work around the federal $10,000 SALT-deduction cap by paying Oregon tax at the entity level. It's been extended through 2027. It's a planning lever, not a requirement — worth a conversation with your accountant.

DIY versus a formation service versus Jupid. Doing it yourself costs the $100 state fee and your time. A formation service charges $0–$300 on top (the "$0" packages still pass through the $100 and then upsell a registered agent and a "compliance" subscription). Jupid forms your Oregon LLC for free — you pay only the state filing fee — and then handles the bookkeeping and tax filings afterward, which, in Oregon, is where almost all the real cost and effort lives.

Forming an Oregon LLC as a non-resident or foreign founder

You can own an Oregon LLC without being a US citizen or resident — Oregon imposes no residency requirement on members or managers. The practical hurdles are an Oregon agent, an EIN, a US bank account, and your US and Oregon tax filings.

Registered agent. If no member or manager is an Oregon resident with a real street address, you must use a commercial registered agent in Oregon. Budget around $100–$150 a year. P.O. boxes and mailbox-store addresses don't qualify.

Getting an EIN without an SSN. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so foreign founders generally can't use it. Instead, file Form SS-4: where it asks for the responsible party's SSN/ITIN/EIN, write "Foreign" — don't invent a number. Submit it by fax or mail, or call the IRS international EIN line (it's not toll-free). Check the current Form SS-4 instructions for the right fax and phone numbers, since the IRS changes them. The EIN is free.

ITIN. An ITIN (Form W-7) is a tax ID for individuals who aren't eligible for an SSN. Your LLC gets an EIN; you as an owner may separately need an ITIN if you have to file a personal US return. ITINs can take a couple of months.

The Form 5472 obligation — don't skip this. A single-member LLC owned by a non-US person is a "foreign-owned disregarded entity" that generally must file Form 5472 along with a pro-forma Form 1120 every year, reporting transactions between the LLC and its foreign owner — even with zero US income. The penalty for missing it is $25,000. Almost no Oregon LLC guide mentions this; build it into your annual calendar from day one.

US bank account. Most US banks want the owner physically present to open a business account, along with the EIN confirmation letter, the filed Articles of Organization, the operating agreement, and a passport. Several fintech business-banking platforms onboard non-resident-owned US LLCs remotely — eligibility and policies change, so check current terms. An Oregon registered agent's street address can often satisfy a "US business address" field.

Oregon tax. Good news first: there's no Oregon sales tax to worry about. But Oregon income tax applies to Oregon-source income, and the Corporate Activity Tax applies if Oregon commercial activity tops $1 million regardless of where you live. Federally, if the LLC is engaged in a US trade or business, the foreign owner has US filing obligations of their own (Form 1040-NR for an individual, plus the Form 5472 filing above). Your tax bill follows where you earn, not where you register.

Registered agents and the Corporate Transparency Act (BOI)

Your registered agent is the person or company designated to receive lawsuits and official notices for the LLC. It has to be an Oregon resident or authorized agent with a physical Oregon street address — and because the agent's address is public, plenty of Oregon residents hire a commercial agent purely to keep their home address off the record.

On the federal beneficial-ownership side: under the Corporate Transparency Act, LLCs were originally required to file a Beneficial Ownership Information (BOI) report with FinCEN. That changed. FinCEN's interim final rule, published in March 2025, redefined a "reporting company" to mean only entities formed under foreign law that register to do business in a US state. As of early 2026, that means an Oregon-formed LLC — even one with foreign owners — has no BOI filing obligation. FinCEN has said it intends to finalize the rule, so this could shift; check fincen.gov/boi before you assume one way or the other. (If you register a foreign-formed entity to do business in Oregon, the BOI rules still apply to that entity.)

Your first 30, 60, and 90 days

Days 1–7

• Get your EIN from the IRS (free; online if you have an SSN/ITIN, otherwise by fax, mail, or phone).
• Adopt your operating agreement — kept with your records, not filed with the state.
• Confirm your registered agent acceptance is on file.
• Check your BOI status. As of early 2026 a domestic Oregon LLC has no FinCEN filing to make; re-verify at fincen.gov/boi.

Days 1–30

• Open a US business bank account (EIN letter, filed Articles, operating agreement, ID).
• Register with the Oregon Employment Department and set up payroll if you'll hire.
• If you operate in Portland/Multnomah, register for the City of Portland and Multnomah County business taxes.
• Get any professional or industry licenses your work requires.
• Look into business insurance — general liability now, workers' comp once you have employees.

Days 1–60

• Set up bookkeeping and a way to track Oregon profit, so you know your income-tax exposure and whether you're approaching the CAT thresholds.
• Talk to an accountant about whether the PTE-E election makes sense for you.
• If you're a foreign-owned single-member LLC, note the annual Form 5472 + pro-forma 1120 filing.

Days 1–90 and ongoing

• Calendar your annual report — due $100 on your LLC's anniversary date, with a 45-day grace period before administrative dissolution. Set a reminder about 45 days out.
• Watch your Oregon commercial activity: register for the CAT at $750,000, file and pay at $1 million.

Common mistakes with Oregon LLCs

Reading "no sales tax" as "low tax." Why it hurts: you skip the planning for a 9.9% income tax, the CAT, and Portland-metro local taxes, then get a far bigger bill than the "no sales tax" headline led you to expect. Fix: treat Oregon as a high-income-tax state with one nice exception (no sales tax), and budget for income tax from day one.

Forgetting the Corporate Activity Tax. Why it hurts: you must register once Oregon commercial activity hits $750,000 — within 30 days — and file and pay over $1 million; miss it and you're exposed to penalties on a tax you didn't know existed. Fix: track Oregon gross receipts monthly so the $750K and $1M lines don't surprise you mid-year.

Ignoring Portland-metro local taxes. Why it hurts: if you operate in Portland or Multnomah County, the city Business License Tax, county Business Income Tax, and the Metro/PFA income taxes stack on top of state tax — and they have their own thresholds and filings. Fix: if you do business in the Portland metro, register for the local taxes and file them alongside your state return.

Missing the anniversary annual report. Why it hurts: it's tied to your formation date, not a fixed calendar date, so a "I'll do it in April like everyone else" mindset gets your LLC administratively dissolved after the 45-day grace period — then reinstatement costs a $100 fee plus $100 per missed report. Fix: put your anniversary date on the calendar with a 45-day warning.

Ignoring Form 5472 as a foreign owner. Why it hurts: a $25,000 penalty for a filing many non-resident owners don't know exists. Fix: set up the pro-forma 1120 + 5472 filing in year one and keep clean records of any money moving between you and the LLC.

Frequently asked questions

How much does it cost to start an LLC in Oregon in 2026? The state filing fee for the Articles of Organization is $100, filed with the Oregon Secretary of State. After that you pay a $100 annual report every year. If you don't have an Oregon address and use a commercial registered agent, add roughly $100–$150 a year. There's no separate franchise tax and no first-year surcharge.

Does Oregon really have no sales tax for my LLC? Correct — Oregon has no state or local general sales tax, which is a real advantage for product and retail businesses. The trade-off is one of the highest income taxes in the country (a graduated rate up to 9.9% on pass-through profit), a Corporate Activity Tax once Oregon commercial activity tops $1 million, and stacked local taxes in the Portland metro.

When is the Oregon LLC annual report due? On your LLC's anniversary date — the anniversary of the day it was formed — every year, for $100. There's a 45-day grace period; miss that and the Secretary of State administratively dissolves (inactivates) your LLC. Reinstating it costs a $100 fee plus $100 for each missed report, so set a reminder about 45 days out.

What is the Oregon Corporate Activity Tax, and will my LLC owe it? The CAT is a tax on Oregon commercial activity (gross receipts), separate from income tax. You must register once Oregon commercial activity reaches $750,000, and you file and pay once it exceeds $1 million. The tax is $250 plus 0.57% of taxable Oregon commercial activity above $1 million, with a 35% subtraction for cost inputs or labor. Most small LLCs never owe it, but a growing one needs to watch the threshold.

Do I need a registered agent for an Oregon LLC? Yes. Every Oregon LLC must keep a registered agent with a physical Oregon street address, available during business hours — a P.O. box doesn't qualify. You can be your own agent if you're an Oregon resident; the LLC itself cannot be its own agent. Out-of-state owners use a commercial registered agent.

Can a non-US resident own an Oregon LLC? Yes. Oregon has no citizenship or residency requirement for members or managers. You'll need an Oregon commercial registered agent and an EIN (which you can get without an SSN), and a single-member foreign-owned LLC must file Form 5472 with a pro-forma Form 1120 every year — the penalty for missing it is $25,000.
