Oregon trades one advantage for another: there's no sales tax anywhere in the state, but personal income tax is steep, with a 9.9% top bracket that kicks in at a lower income threshold than most comparable states. For growing LLCs, the Corporate Activity Tax adds a gross-receipts layer once commercial activity crosses $1 million.
This guide covers exactly what an Oregon LLC owes in 2026: the four-bracket income tax and its unusually low top-rate threshold, when the Corporate Activity Tax actually applies, the $100 Annual Report and its strict 45-day dissolution window, and when an S-Corp election is worth it given Oregon's steep rates.
Oregon Personal Income Tax on LLC Profit
By default, an Oregon LLC is a pass-through entity — the LLC itself pays no separate Oregon income tax. Profit flows through to the owners' personal returns, taxed once at the federal level and once at Oregon's graduated rate (4.75%–9.9%) on top, with the 9.9% top rate reachable at a lower income threshold than most other states with similar top brackets.
Oregon's rate: Graduated, 4 brackets from 4.75% to 9.9%
Single-filer brackets: 4.75% up to $4,350; 6.75% from $4,350–$10,900; 8.75% from $10,900–$125,000; 9.9% above $125,000 (joint-filer thresholds roughly double). Oregon's top bracket kicks in at a relatively low income threshold compared to other graduated-tax states, so profitable LLC owners reach the 9.9% marginal rate faster than they might expect.
Oregon relies heavily on income tax revenue precisely because it has no general sales tax to diversify collections — one reason its top bracket is among the steepest in the country.
Oregon's Corporate Activity Tax (CAT)
Oregon has no LLC franchise tax or minimum annual tax. The Corporate Activity Tax is the one entity-level obligation to watch, but it's threshold-triggered: most small and early-stage LLCs stay well under the $750,000 registration trigger and owe nothing, with actual liability only kicking in above $1 million in Oregon commercial activity.
Registration is required once Oregon commercial activity exceeds $750,000, but the actual filing and payment threshold is $1 million or more. Distributive income received by LLC members from the entity is generally excluded from CAT at the member level — the tax is assessed once, at the entity generating the receipts, not layered again on the owner's personal return. Oregon recognizes the federal S-Corp election with no separate state election, and CAT applies the same regardless of that election since it's based on gross commercial activity, not entity type.
Oregon Sales Tax
Nobody. Oregon has no state or local sales tax, so LLCs selling goods or services within Oregon never need to register for, collect, or remit sales tax on those in-state sales.
- State rate: 0%
- There's no sales tax registration process at all for Oregon LLCs, since the state has no general sales tax — one of only five states in the country in that position.
Oregon Annual Report Requirement
Oregon requires every LLC to file Annual Report with the Oregon Secretary of State, due The LLC's anniversary date each year. Filing fee: $100 (domestic); $275 (foreign).
There's no stated flat-dollar late fee, but Oregon gives only a 45-day grace period after the due date. If the report still isn't filed by then, the Secretary of State administratively dissolves the LLC.
Reinstatement requires filing a Reinstatement form, paying a $100 penalty fee, plus the $100 filing fee for each Annual Report that was missed — the cost compounds the longer it's left unaddressed.
Federal Self-Employment Tax and How Your Oregon LLC Is Classified
Regardless of which state you're in, LLC owners who materially participate in the business owe federal self-employment tax — 15.3% on net profit, covering Social Security (up to the $184,500 (2026) wage base) and Medicare (no cap).
Single-Member LLCs
A single-member Oregon LLC defaults to a disregarded entity for federal tax purposes — you report income and expenses on Schedule C of your personal Form 1040 and compute self-employment tax on Schedule SE. Oregon adds its graduated income tax on top at the personal level.
Multi-Member LLCs
A multi-member Oregon LLC defaults to partnership taxation, filing an informational Form 1065 and issuing each member a Schedule K-1. There's no Oregon-specific filing consequence tied to member count, though CAT registration and filing (if triggered) apply at the entity level either way.
Should Your Oregon LLC Elect S-Corp Taxation?
An S-Corp election lets you split LLC profit into a reasonable salary (payroll-taxed) and distributions (not subject to self-employment tax), once the business is consistently profitable enough to justify the added payroll complexity.
Oregon's treatment: Oregon recognizes the federal S-Corp election with no separate state election required. The Corporate Activity Tax applies independently of S-Corp status, so electing it doesn't change your CAT exposure one way or the other.
With Oregon's steep 9.9% top marginal rate reached at a relatively low income threshold, and no sales tax to offset that burden elsewhere in the state's revenue mix, the federal SE-tax savings from an S-Corp election can be especially valuable for Oregon LLC owners with meaningful profit. Just remember the CAT (if your LLC crosses $750,000–$1 million in gross receipts) applies regardless of the election, so it's a separate line item to plan for either way.
Oregon LLC Tax Costs at a Glance
How to Handle Your Oregon LLC's Taxes
If You Do It Yourself
Step 1 — Get your federal EIN before anything else.
Apply for your EIN for free directly at irs.gov — a purely federal application with no Oregon-specific step.
Step 2 — Confirm your default federal tax classification.
A single-member LLC defaults to a disregarded entity (Schedule C); a multi-member LLC defaults to partnership taxation (Form 1065 plus Schedule K-1 for each member). Neither requires a separate election — this is automatic unless you file Form 8832 or Form 2553 to change it.
Step 3 — Register with the Oregon Department of Revenue if required for state income tax withholding or estimated payments.
Oregon relies heavily on income tax revenue precisely because it has no general sales tax to diversify collections — one reason its top bracket is among the steepest in the country.
Step 4 — Register for sales tax if you sell taxable goods or services.
Register with the Not applicable — Oregon has no sales tax at oregon.gov/dor before your first taxable sale. There's no sales tax registration process at all for Oregon LLCs, since the state has no general sales tax — one of only five states in the country in that position.
Step 5 — Register for payroll/reemployment tax the moment you hire your first employee.
The moment you hire your first employee, register with the Oregon Employment Department. The 2026 new-employer UI rate is 2.4%, applied to a taxable wage base of $56,700 — notably one of the highest UI wage bases nationally. Oregon also imposes a statewide transit tax withheld from employee wages, with a best-estimate rate of approximately 0.08% — confirm the exact current figure directly with the Department of Revenue before relying on it for payroll setup.
Step 6 — Set up quarterly estimated tax payments.
If you expect to owe $1,000 or more in combined federal and Oregon tax for the year, both the IRS and the Department of Revenue expect quarterly estimated payments covering income tax and federal self-employment tax on your LLC profit.
Step 7 — Calendar your Corporate Activity Tax (CAT) due date.
Corporate Activity Tax (CAT) (Form OR-CAT) is due 15th day of the 4th month after year-end (April 15 for calendar-year filers), $250 plus 0.57% of Oregon commercial activity above $1 million. Missing it puts your LLC in bad standing with the Oregon Department of Revenue.
Step 8 — File your Annual Report every Oregon deadline.
Annual Report is due The LLC's anniversary date each year with the Oregon Secretary of State, $100 (domestic); $275 (foreign) fee.
Step 8 — Decide whether an S-Corp election makes sense once your LLC is consistently profitable.
With Oregon's steep 9.9% top marginal rate reached at a relatively low income threshold, and no sales tax to offset that burden elsewhere in the state's revenue mix, the federal SE-tax savings from an S-Corp election can be especially valuable for Oregon LLC owners with meaningful profit. Just remember the CAT (if your LLC crosses $750,000–$1 million in gross receipts) applies regardless of the election, so it's a separate line item to plan for either way.
Step 9 — Watch for Oregon-specific tax traps.
No sales tax is a genuine competitive advantage, but it's often misread as 'Oregon has no business taxes' — the Corporate Activity Tax, the $100 Annual Report with its unusually hard 45-day dissolution trigger, the statewide transit tax on wages, and Oregon's steep 9.9% top income bracket are all real, recurring costs. The $56,700 UI wage base is also far higher than most peer states, meaningfully raising payroll costs for Oregon employers with several employees.
Step 10 — Keep business and personal finances completely separate.
Commingling funds is the single biggest reason courts pierce the LLC liability shield, and it also makes tax preparation far more error-prone. Run all business income and expenses through a dedicated business bank account and keep receipts.

When Should You Talk to a Tax Professional About Your Oregon LLC?

Frequently Asked Questions
No. Oregon has no LLC franchise tax or minimum annual tax. The one entity-level tax to watch is the Corporate Activity Tax, which only applies once Oregon commercial activity exceeds $750,000 (registration) to $1 million (actual filing/payment) — most small LLCs owe nothing.

It depends on your profit level.

If your LLC does business in a state other than the one it's formed in — an office, employees, inventory, or significant sales there — you may have created nexus requiring registration and tax obligations in that state too. This is fact-specific and worth a conversation with a tax professional if you operate in multiple states.
For a typical Oregon LLC with in-state owners and no employees: graduated state income tax from 4.75% up to 9.9% on your share of profit, no franchise tax below the Corporate Activity Tax's $1 million threshold, just the $100 Annual Report, plus federal income tax and 15.3% federal self-employment tax (up to the $184,500 Social Security wage base for 2026). There's no sales tax on any goods or services you sell.
Yes. LLC Attorney's ongoing compliance subscription tracks your Oregon filing deadlines, handles your Annual Report, and connects you with flat-fee attorney consultations (no retainer) when a tax question needs a licensed professional's judgment call.
