Fees
Oregon LLC formation costs
$100 OR Articles of Organization (one-time) + $100/yr OR Annual Report + Portland Business License Tax 2.6% of net income + Multnomah County Business Income Tax 2% of net income (stacking effect — the #1 Portland founder surprise) = $200 first-year OR state cost + city/county taxes on profitable LLCs. Oregon has no sales tax. The Portland + Multnomah County income tax stack (2.6% + 2%) means profitable Portland LLCs face up to 4.6% in local income taxes on top of Oregon's top personal income tax rate of 9.9%.
| Fee | Amount | Notes |
|---|---|---|
| Articles of Organization filing fee (OR SOS) | $100 | One-time state filing fee payable to the Oregon Secretary of State at sos.oregon.gov. Standard $100 formation fee — in line with Florida ($100), Georgia ($100), and Wyoming ($100). File online for fastest processing (1–2 business days). |
| Oregon Annual Report | $100/year | Oregon LLCs must file an Annual Report in the LLC's anniversary month each year. Fee: $100 — higher than states like Colorado ($10/yr) and Michigan ($25/yr), but comparable to Wyoming ($60/yr Annual License Tax) and lower than North Carolina ($200/yr). File online at sos.oregon.gov. Failure to file results in administrative dissolution. |
| Portland Business License Tax (2.6% of net income) | 2.6% of Oregon net income allocated to Portland (applies over $50,000 gross receipts threshold) | Portland levies a Business License Tax of 2.6% on Oregon net income for businesses with Portland gross receipts over $50,000. This is Portland's primary city-level business tax. Register through the City of Portland Revenue Division at portland.gov/revenue. Unlike most city 'license fees,' Portland's Business License Tax is a true income tax on net earnings — it applies on top of Oregon state income tax. |
| Multnomah County Business Income Tax (2.0% of net income) | 2.0% of Multnomah County-sourced net income (applies over $50,000 gross receipts threshold) | Multnomah County levies a Business Income Tax of 2.0% on Multnomah County-allocated net income for businesses with county gross receipts over $50,000. This STACKS on top of the Portland Business License Tax — the combined city + county rate is approximately 4.6% of net income. Register through the Multnomah County Revenue Division. This stacking effect is the #1 Portland LLC surprise for founders relocating from low-local-tax states. |
| Oregon minimum excise tax (if C-corp elected) | $150–$100,000+ (based on OR gross receipts, for C-corp-elected LLCs) | LLCs that elect C-corp treatment in Oregon are subject to Oregon's minimum corporate excise tax, which ranges from $150 (under $500K gross receipts) to $100,000+ (over $100M gross receipts). Most Portland pass-through LLCs are NOT subject to this tax — it applies only to C-corp-elected entities. |
| EIN application | Free | IRS Form SS-4 — free online at irs.gov/ein. No Oregon or Portland fee. |
Requirements
What you need to know before filing
- Name must contain 'LLC', 'L.L.C.', 'Limited Liability Company', or 'Limited Liability Co.' — Oregon accepts standard designators under ORS § 63.094.
- A registered agent with a physical Oregon street address (no PO boxes) must be maintained at all times. The RA must be available during normal business hours to accept service of process. Oregon residents may self-serve as RA.
- Articles of Organization are filed with the Oregon Secretary of State at sos.oregon.gov. Filing fee: $100. Standard online processing: 1–2 business days.
- Oregon LLCs must file an Annual Report with the Oregon Secretary of State each year. The Annual Report is due on the LLC's anniversary month and costs $100. File online at sos.oregon.gov.
- An Operating Agreement is not required to be filed with the state but is strongly recommended under ORS § 63.057 to govern member rights, profit sharing, voting, and dissolution.
- Oregon has no state sales tax — a significant advantage for businesses selling goods or services in Oregon. No sales tax registration is required.
- Oregon imposes a personal income tax with a top marginal rate of 9.9% on income over $125,000 (2024). Pass-through LLC income is taxed at the individual member level via Oregon's personal income tax.
- Portland Business License Tax: Portland levies a Business License Tax of 2.6% of Oregon net income (for businesses with Portland gross receipts over $50,000). This is Portland's primary city-level tax on business income — separate from Oregon state income tax and Multnomah County taxes.
- Multnomah County Business Income Tax: Multnomah County (where Portland is the county seat) levies a Business Income Tax of 2.0% of Multnomah County-sourced net income (for businesses with Multnomah County gross receipts over $50,000). This stacks on top of the Portland Business License Tax — the combined city + county local income tax burden is up to 4.6% of net income. This is the #1 Portland founder surprise.
- The Portland + Multnomah County income tax stacking effect means that a profitable Portland LLC paying both taxes faces effective local income taxes of approximately 4.6%, on top of Oregon's top personal income tax rate of 9.9% — making Portland's combined state + local income tax burden one of the highest in the US.
- Oregon has no franchise tax on LLCs. The $100/yr Annual Report is an administrative filing fee, not a franchise or privilege tax.
- Portland is Oregon's largest city and the Pacific Northwest's second-largest metro (after Seattle). Key industries: technology, outdoor recreation (Nike, Adidas North America), healthcare, manufacturing, and a significant small-business and freelance economy.

Registered agent
Who receives legal mail for your LLC
Required in every state.
- Required?
- Yes
- Who can serve
- Oregon resident individual with a physical Oregon street address (no PO boxes), or a business entity authorized to transact business in Oregon and maintaining a physical Oregon street address
- Can I serve myself?
- Yes
- Commercial RA cost
- ~$100/yr
Oregon Articles of Organization require the registered agent name and address but do not require member names on the public filing. Using a commercial RA service keeps your personal address off the public sos.oregon.gov record and ensures reliable receipt of Annual Report reminders, Portland/Multnomah County tax notices, and legal process service.

Process
How to form a LLC in Oregon
Sequential — each step gates the next.
-
Check name availability with the Oregon SOS Search the Oregon Secretary of State business name database at sos.oregon.gov to confirm your desired LLC name is available and not deceptively similar to an existing Oregon entity. The name must include a valid designator under ORS § 63.094. Oregon allows name reservations for 120 days ($100 fee) while preparing Articles.
-
Appoint an Oregon registered agent Designate a registered agent with a physical Oregon street address — no PO boxes. Oregon residents may self-serve as RA. Out-of-state owners and remote founders operating in Portland typically use a commercial RA service ($50–$150/yr) to maintain a compliant Oregon address and keep personal address off the public SOS record.
-
File Articles of Organization with the Oregon SOS ($100) File online at sos.oregon.gov. The Articles require the LLC name, registered agent name and Oregon street address, principal office address, and organizer signature. Pay the $100 filing fee. Standard online processing: 1–2 business days — among the fastest in the Pacific Northwest.
-
Draft an Operating Agreement Oregon's LLC Act (ORS Chapter 63) provides default rules, but an Operating Agreement is critical for all Portland LLCs — particularly multi-member structures in technology, healthcare, outdoor recreation, and real estate. The OA governs member ownership percentages, voting rights, profit allocations, capital contributions, management authority, and dissolution. Not filed with the state.
-
Obtain an EIN from the IRS After the Articles are approved, apply for an EIN at irs.gov/ein. The online application takes under 15 minutes and issues the EIN immediately. Print the CP 575 EIN Confirmation Letter for bank account opening and Portland/Multnomah County tax registrations.
-
Register for Portland Business License Tax (if gross receipts will exceed $50,000) If the LLC's Portland gross receipts will exceed $50,000, register with the City of Portland Revenue Division at portland.gov/revenue for the Portland Business License Tax (2.6% of Oregon net income). Registration is required before reaching the gross receipts threshold. The Portland Business License Tax is Portland's primary city-level income tax on businesses — it is not a flat fee but a tax on net income.
-
Register for Multnomah County Business Income Tax (if gross receipts will exceed $50,000) If the LLC's Multnomah County gross receipts will exceed $50,000, register with Multnomah County for the Multnomah County Business Income Tax (2.0% of Multnomah County-sourced net income). Register through the Multnomah County Revenue Division. The Multnomah County tax STACKS on top of the Portland Business License Tax — combined city + county local income tax rate: up to 4.6% of net income. This is the #1 Portland LLC cost surprise.
-
File the Oregon Annual Report in your anniversary month ($100) Oregon LLCs must file an Annual Report with the Secretary of State in the LLC's anniversary month each year. Fee: $100. The Annual Report confirms the registered agent, principal office address, and member/manager information. File online at sos.oregon.gov. Failure to file results in administrative dissolution after a grace period.
-
Open a business bank account Bring your EIN Confirmation Letter, Articles of Organization, and Operating Agreement to the bank. Portland-area banks (Umpqua Bank — headquartered in Portland — Banner Bank, Chase, Wells Fargo, US Bank, OnPoint Community Credit Union) require formation documents and an EIN. A separate business account maintains the LLC's liability shield and is required for S-corp election if applicable.
Annual obligations
What your LLC owes every year
Year-2+ costs most formation guides omit.
| Obligation | Due date | Fee | Consequence if missed |
|---|---|---|---|
| Oregon Annual Report | In the LLC's anniversary month each year | $100.00 | Failure to file the Annual Report results in administrative dissolution after a grace period. The LLC becomes legally inoperative until reinstated by filing the delinquent Annual Report and paying all outstanding fees. |
| Portland Business License Tax (annual return) | April 15 (calendar-year filers); or 15th day of 4th month after fiscal year end | $0.00 | Penalties and interest for failure to register, file, and pay Portland's 2.6% Business License Tax on net income allocated to Portland. Required for LLCs with Portland gross receipts over $50,000. The fee_usd here is $0 because the actual tax is income-based; the return must be filed even if no tax is owed. |
| Multnomah County Business Income Tax (annual return) | April 15 (calendar-year filers); or 15th day of 4th month after fiscal year end | $0.00 | Penalties and interest for failure to register, file, and pay Multnomah County's 2.0% Business Income Tax on county-sourced net income. Required for LLCs with Multnomah County gross receipts over $50,000. Filed concurrently with the Portland Business License Tax return through the Portland combined business tax return system. |

If you skip the LLC
- Operating as a sole proprietor in Portland without an LLC means unlimited personal liability — in Oregon's active real estate, technology, and construction markets, personal asset exposure is a material risk.
- Without an LLC, the business name is not protected in Oregon; another entity can register the same name as an Oregon LLC and force a rebrand.
- Sole proprietors cannot elect S-corp tax treatment (available to LLCs). At $80,000+ in net income, S-corp election typically saves $3,000–$8,000/year in self-employment taxes — particularly valuable in Portland given the high local income tax burden.
- Operating in Portland with gross receipts over $50,000 without registering for the Portland Business License Tax exposes the business to back-taxes, penalties, and interest assessed by the City of Portland Revenue Division.
- Failure to file the Oregon Annual Report in the anniversary month results in administrative dissolution after a grace period, making the LLC legally inoperative until reinstated.
Formation context
Who should form in Oregon?
- Recommended for
- Portland-area entrepreneurs, technology professionals, and small business owners forming directly in Oregon to serve a local market — in-state formation avoids dual-state compliance costs; Outdoor recreation, healthcare, sustainable manufacturing, and technology LLCs based in Portland that benefit from Oregon's no-sales-tax environment and the Portland startup ecosystem; Founders who understand the Portland + Multnomah County income tax stacking effect and want to operate in Portland's market with properly formed and tax-registered entity structures
- Tax treatment (default)
- Pass-through by default at the federal level: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). Oregon taxes pass-through LLC income at the individual member level via Oregon's progressive personal income tax (4.75%–9.9%). Oregon has no franchise tax on LLCs. Portland's Business License Tax (2.6%) and Multnomah County's Business Income Tax (2.0%) stack on top of Oregon state income taxes for LLCs with gross receipts above $50,000 in those jurisdictions. Oregon has no sales tax.
For businesses physically operating in Portland, forming directly in Oregon ($100 + $100/yr Annual Report) avoids the dual-state cost trap. A Wyoming or Delaware LLC operating in Portland must register as a foreign LLC in Oregon (~$275 foreign registration), pay both states' annual fees, AND comply with all Oregon Annual Report, Portland Business License Tax, and Multnomah County Business Income Tax requirements. Oregon's income taxes apply to Portland-based income regardless of where the LLC is formed — there's no tax avoidance benefit from forming out-of-state for a Portland operating business.
No publication requirement in Oregon — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.
FAQ
Common Oregon (Portland) LLC formation questions
Does Oregon have a sales tax?
No. Oregon is one of five US states with no state sales tax (along with Montana, New Hampshire, Delaware, and Alaska). Portland businesses selling goods or services do not need to collect or remit sales tax. This is a significant compliance simplification — no sales tax license, no sales tax collection, no monthly/quarterly sales tax filings. However, Portland and Multnomah County impose income-based business taxes that more than offset the sales-tax simplification for profitable businesses.
What is the Portland Business License Tax?
Portland's Business License Tax is 2.6% of Oregon net income allocated to Portland, for businesses with Portland gross receipts over $50,000. This is Portland's primary city-level tax on business earnings — not a flat annual fee, but a true income tax. Register with the City of Portland Revenue Division at portland.gov/revenue. The tax is due with your annual Portland combined business tax return.
What is the Multnomah County Business Income Tax, and how does it stack with Portland's tax?
Multnomah County's Business Income Tax is 2.0% of Multnomah County-allocated net income, for businesses with county gross receipts over $50,000. It stacks directly on top of Portland's 2.6% Business License Tax — the combined local income tax burden is approximately 4.6% of net income. This stacking effect is the #1 Portland LLC cost surprise. A profitable LLC with $200,000 in Portland/Multnomah net income faces approximately $9,200 in combined city + county income taxes, on top of Oregon's up-to-9.9% personal income tax.
How much does it cost to form an LLC in Portland, OR?
Oregon Articles of Organization: $100 (one-time). Oregon Annual Report: $100/yr. Portland Business License Tax: 2.6% of net income (if over $50K gross receipts). Multnomah County Business Income Tax: 2.0% of net income (if over $50K gross receipts). Commercial RA service: $50–$150/yr. Total first-year state cost for most Portland startups: $200–$350 (before local income taxes which vary by profitability).
How does Portland compare to Seattle for PNW LLC formation?
Portland and Seattle are the two primary Pacific Northwest LLC formation hubs. Oregon: $100 formation + $100/yr Annual Report + Portland Business License Tax (2.6% net income) + Multnomah County Business Income Tax (2.0% net income) + Oregon personal income tax (up to 9.9%) + NO sales tax. Washington/Seattle: $200 formation + $71/yr Annual Report + Seattle Business License Tax (B&O tax variant) + Washington state Business and Occupation (B&O) tax (gross receipts-based, not income-based) + NO personal income tax (WA has none) + 10.25% combined sales tax. Key difference: Oregon taxes net income (Portland/OR LLC loses on high-income years); Washington taxes gross receipts (Seattle/WA LLC loses on high-revenue, low-margin businesses). For high-margin professional services, Washington's no-personal-income-tax advantage is significant. See the Seattle vs. Portland LLC guide (coming soon).
Does Portland require a separate business license from the Oregon state filing?
Yes — Portland's Business License Tax registration is separate from Oregon's Secretary of State LLC registration. If your LLC's Portland gross receipts exceed $50,000, register with the City of Portland Revenue Division at portland.gov/revenue before reaching the threshold. Similarly, Multnomah County's Business Income Tax registration is separate. Both city and county taxes are administered through a combined Portland combined business tax return system — file one return, pay both taxes.
What is Oregon's personal income tax rate for LLC members?
Oregon has a top marginal personal income tax rate of 9.9% on income over $125,000 (single filers) or $250,000 (married filing jointly) for 2024. Lower brackets: 4.75% ($0–$17,400), 6.75% ($17,400–$44,100), 8.75% ($44,100–$125,000). Pass-through LLC income is taxed at the individual member level via these rates. Combined with Portland's 2.6% Business License Tax and Multnomah County's 2.0% Business Income Tax, Portland LLCs face one of the highest effective local income tax burdens in the US for high-income members.

Should I form an LLC?
Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.
LLC vs S-Corp vs Sole Prop vs C-Corp — compare all four →Reduce your tax bill
Should you elect S-Corp status for your Oregon LLC?
Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

DBA vs LLC — do you actually need a full LLC?
Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

How to pay yourself from your Oregon LLC
How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.
