Oregon LLC Taxes Explained: No Sales Tax, 9.9% Income Tax (2026)
Oregon's tax story has two sides: genuinely no sales tax, but a graduated income tax that reaches a 9.9% top rate faster than almost any other state. Here's every layer your LLC touches, with an estimator and the Corporate Activity Tax explained clearly.
A default Oregon LLC is a pass-through: profits land on your personal return, taxed at Oregon's graduated income tax, topping out at 9.9% — reached at just $125,000 of taxable income for single filers ($250,000 married filing jointly). Add 15.3% federal self-employment tax on 92.35% of net profit. The LLC owes no entity-level income tax by default, and Oregon has no sales tax. The Corporate Activity Tax (CAT) — a gross receipts tax applying to all entity types — kicks in only above $1 million in Oregon commercial activity, calculated as $250 plus 0.57% of the excess (with registration required above $750,000).

The 9.9% Top Rate — Reached Quickly
Oregon's income tax brackets for 2026 (single filers): 4.75% on the first $4,350, 6.75% from $4,350–$10,900, 8.75% from $10,900–$125,000, and 9.9% above $125,000 (married filing jointly thresholds roughly double). Because the 8.75% bracket begins at just $10,900, most working Oregon adults are already taxed at that rate on the bulk of their income, and profitable LLC owners typically reach the 9.9% top bracket faster than they would in most other high-tax states — California's top rate, for comparison, only applies above roughly $698K, and Hawaii's only above roughly $200K.
The Corporate Activity Tax (CAT)
This is separate from your income tax — and applies to all entity types, including LLCs. The Oregon CAT is a gross receipts tax: registration is required within 30 days of exceeding $750,000 in Oregon-sourced commercial activity in a calendar year. Payment is only owed once taxable commercial activity exceeds $1 million, calculated as $250 plus 0.57% of the amount over $1 million, after a 35% subtraction for the greater of cost of goods sold or labor costs. Quarterly estimated payments are required if your CAT liability is expected to exceed $5,000. Most first-year businesses fall well below the threshold — but track your Oregon-sourced gross receipts as you grow.
The Kicker Law — A Uniquely Oregon Feature
Oregon has a distinctive budget mechanism called the "kicker." When actual state revenue exceeds official projections by more than 2%, the entire surplus is returned to taxpayers as a credit on the following year's tax return, rather than being retained by the state. This doesn't change your annual tax planning in a predictable way — it depends on state revenue performance — but it's a genuinely unique feature of Oregon's tax system worth knowing about.
The S-Corp Question (~$60–80K Profit)
An S-Corp election changes federal taxation only: reasonable salary (payroll-taxed) plus distributions that escape the 15.3% SE tax. File Form 2553 — never Form 8832, which is the C-Corp election. Break-even lands around $60–80K of consistent profit after payroll and accounting costs. Distributions still face Oregon's graduated income tax as income — the election shields SE tax, not state income tax. Run your numbers in the S-Corp election guide.

Ahmad Adil's Take: Oregon's tax reputation as a "no sales tax state" is accurate but incomplete, and I want every founder here to see the full picture before they form. The 9.9% top income tax rate, reached at a genuinely modest $125,000, is the number that actually determines your real tax bill as a profitable LLC owner — and it will very likely outweigh whatever you'd have saved on sales tax elsewhere. That's not a reason to avoid Oregon if you're actually building your life and business here — it's a reason to plan with real numbers rather than the "no sales tax" headline alone. The Corporate Activity Tax is the other one to watch as you scale: it doesn't touch most new LLCs, but $1M in Oregon commercial activity arrives faster than founders expect once a business is genuinely growing.
