Oregon has no general sales tax, so an Oregon sales tax nexus does not exist in the way it does in almost every other state. Out-of-state sellers do not register to collect Oregon sales tax, do not charge it at checkout, and do not track transaction counts against a Wayfair-style threshold. What Oregon does have is a gross-receipts tax called the Corporate Activity Tax, which creates an economic nexus once your Oregon-sourced receipts reach $750,000 in a calendar year, plus a set of product-specific excise taxes that operate much like sales taxes for particular goods.
No Sales Tax, No Wayfair Threshold
Oregon is one of five states with no statewide sales or use tax on retail transactions.1Tax Foundation. State and Local Sales Tax Rates, 2026 The others are Alaska, Delaware, Montana, and New Hampshire. Because there is no sales tax, the framework from South Dakota v. Wayfair that reshaped remote-seller obligations across most of the country has no direct application here.2Supreme Court of the United States. South Dakota v. Wayfair, Inc. You will not find an Oregon version of the $100,000 or 200-transaction thresholds used elsewhere.
If your only question is whether to charge Oregon customers sales tax at checkout, the answer is no. The obligations that do exist are separate from that checkout question and apply to the business itself, not to the buyer.
The Corporate Activity Tax Threshold
The Corporate Activity Tax, enacted in 2019 under ORS 317A, is a gross-receipts tax on commercial activity sourced to Oregon. It is not a sales tax, not an income tax, and not something your customers see on an invoice. It hits the business directly based on Oregon-connected receipts.
Two dollar figures drive compliance:
- At $750,000 in Oregon commercial activity in a calendar year, you must register with the Oregon Department of Revenue.3Oregon State Legislature. Oregon Code 317A – Corporate Activity Tax
- At $1 million, you owe tax. The rate is $250 plus 0.57 percent of taxable commercial activity above $1 million.4Oregon Department of Revenue. Corporate Activity Tax (CAT)
Physical presence in Oregon is not required. A company with no employees, no office, and no inventory in the state still triggers the registration obligation once its Oregon-sourced receipts cross $750,000. You have 30 days after crossing that line to register.3Oregon State Legislature. Oregon Code 317A – Corporate Activity Tax
How Oregon Sources Your Receipts
Whether a sale counts toward the $750,000 threshold depends on Oregon’s market-based sourcing rules. The focus is on where the customer receives the benefit, not where your staff performs the work.
- Tangible goods are sourced to Oregon if delivered to an Oregon location.
- Real property receipts are sourced to Oregon if the property is located in Oregon.
- Services are sourced to where the customer’s market exists, meaning where the service is delivered, not where it is performed.
- Rentals and leases of tangible property are sourced based on the proportion of time the property is used in Oregon.
Professional services get special treatment because their delivery location can be characterized in multiple ways, so the rules require a reasonable approximation based on the facts.5Oregon Public Law. OAR 150-317-1040 – Sourcing Commercial Activity to Oregon A consulting firm billing an Oregon client for work performed from another state will likely count that revenue toward its Oregon total.
What Doesn’t Count Toward the Threshold
Not every dollar flowing through your business counts as commercial activity. Oregon excludes several categories from the definition:3Oregon State Legislature. Oregon Code 317A – Corporate Activity Tax
- Interest income, unless it comes from credit sales or is earned by a financial institution.
- Proceeds from selling capital assets described under IRC Sections 1221 or 1231, regardless of holding period.
- Receipts from hedging transactions entered primarily to protect a financial position.
- Loan principal repayments, bond redemptions, and similar returns of principal.
- Insurance proceeds from policies you own, unless the payout replaces lost commercial activity.
- Money received from issuing your own stock, options, or warrants.
- Gifts, charitable contributions, and membership dues received by trade and professional associations.
- Wages and benefits received by individuals for services rendered to an employer.
A business with high gross revenue could fall below the $750,000 registration threshold once excluded receipts are stripped out. Working this calculation carefully matters, because the penalty clock starts 30 days after you actually cross the line.
The 35 Percent Subtraction
Once you owe tax, Oregon lets you reduce taxable commercial activity by 35 percent of the greater of your cost inputs or your labor costs.4Oregon Department of Revenue. Corporate Activity Tax (CAT) This is the main relief valve in a tax that otherwise ignores whether you made a profit.
Cost inputs means cost of goods sold as calculated for federal tax purposes. Labor costs means total employee compensation, with compensation for any single employee capped at $500,000 for this calculation.6Oregon Department of Revenue. Corporate Activity Tax – Labor Costs and Cost Inputs Farming operations that don’t report cost of goods sold on their federal return can use operating expenses (minus labor) instead. Payroll taxes such as the employer’s share of Social Security and Medicare do not count as labor costs for this subtraction.
The subtraction only applies to costs attributable to Oregon commercial activity, not total business expenses nationwide. A company doing 20 percent of its business in Oregon would generally apply the subtraction to 20 percent of its eligible costs.
Public Law 86-272 Will Not Save You
Out-of-state sellers of tangible goods sometimes assume federal Public Law 86-272 protects them from Oregon tax obligations. That law limits Oregon’s ability to impose a net income tax on companies whose only in-state activity is soliciting orders for tangible goods, with orders approved and shipped from outside Oregon.7Oregon Department of Revenue. Foreign Corporations
The distinction matters. PL 86-272 applies to net income taxes. The CAT is a gross-receipts tax. A company shielded from Oregon’s corporate income tax by PL 86-272 can still owe the CAT once its Oregon-sourced commercial activity crosses the thresholds. PL 86-272 also offers no protection for companies selling services or licensing intangible property, so revenue from software subscriptions, consulting, or intellectual property licensing directed at Oregon customers has no federal shield.
Registration, Filing, and Unitary Groups
Registration happens through the Oregon Department of Revenue’s Revenue Online portal. You’ll need your legal business name as it appears on federal filings, your Federal Employer Identification Number, your North American Industry Classification System code, your entity type, and the date you crossed $750,000. That date becomes your nexus start date.
After submitting, you receive a confirmation number immediately, with formal approval typically arriving within a few weeks. If estimated annual CAT liability exceeds $5,000, quarterly estimated payments are required, due April 30, July 31, October 31, and January 31. The annual return is due April 15 following the close of the tax year.4Oregon Department of Revenue. Corporate Activity Tax (CAT)
Businesses that are part of a unitary group register, file, and pay as a single taxpayer. The $750,000 threshold applies to the combined Oregon commercial activity of the entire group, not each member individually.8Oregon Department of Revenue. Questions About Unitary Groups This catches affiliated companies that might each fall below the threshold but collectively exceed it.
Penalties for Missing the Threshold
Failing to register when required triggers a penalty of up to $100 per month, capped at $1,000 per calendar year, with the clock starting 30 days after commercial activity crosses $750,000.3Oregon State Legislature. Oregon Code 317A – Corporate Activity Tax
Underpaying quarterly estimated taxes carries a 5 percent penalty on the underpayment amount for each quarter where a shortfall exists.9Oregon Public Law. OAR 150-317-1310 – Estimated Tax Payments Interest accrues on top of penalties for late payments. The real exposure is usually not the penalty itself but the back-tax liability that builds when a business crosses the threshold without realizing it and goes multiple years without filing.
Excise Taxes That Behave Like Sales Taxes
Oregon has no general sales tax, but it does impose targeted excise taxes on specific products that businesses must collect at the point of sale. Each has its own registration and remittance track.
Marijuana
Licensed retailers charge a 17 percent tax on all recreational marijuana sales at retail and register separately with the Department of Revenue.10Oregon Department of Revenue. Marijuana Tax
Tobacco Products
Cigars and most other tobacco products are taxed at 65 percent of wholesale price, with cigars capped at $1 per unit. Moist snuff is taxed at $1.89 per ounce effective July 2026. Oral nicotine products in packages of 20 or fewer units carry a $0.65 per-package tax.11Oregon Department of Revenue. Tobacco Products Tax and Licensing
Transient Lodging
The statewide lodging tax is 1.5 percent of the amount charged for occupancy.12Oregon Department of Revenue. Transient Lodging Tax Many cities and counties layer additional local lodging taxes on top, so the total collected by a hotel or short-term rental operator is often significantly higher.
Heavy Equipment Rentals
Qualified providers collect a 2 percent tax on the rental price of heavy equipment and tools. A provider is “qualified” when more than 50 percent of prior fiscal year rental revenue came from renting construction, mining, earthmoving, or industrial equipment. Returns are filed quarterly by the county where each rental facility is located.13Oregon Department of Revenue. Heavy Equipment Rental Tax
Bicycles
Oregon imposes a $15 flat excise tax on the sale of new bicycles with wheels of at least 26 inches in diameter and a retail price of $200 or more.
Vehicle Privilege and Use Taxes
Oregon’s vehicle taxes catch many buyers off guard in a no-sales-tax state. The vehicle privilege tax applies to dealers selling new taxable vehicles in Oregon at 0.5 percent of retail price.14Oregon Department of Revenue. Vehicle Privilege and Use Taxes A matching 0.5 percent vehicle use tax applies when a vehicle purchased from an out-of-state dealer is brought into Oregon. The tax is technically on the dealer or the vehicle owner rather than structured as a sales tax, but the economic effect is the same: a $40,000 vehicle carries an extra $200.
Local Business Taxes and Transit Assessments
State-level obligations do not exhaust the picture. Several Oregon localities impose their own business taxes, sometimes with lower thresholds than the CAT.
The City of Portland and Multnomah County operate a combined business tax administration system, jointly managed since 1993.15Portland.gov. Business Tax Filing and Payment Information Any business operating within city or county boundaries must register for a Revenue Division tax account within 60 days. A business that owes nothing at the state level can still have local obligations in Portland.
Employers and self-employed individuals in certain metro areas also face transit district payroll taxes. The TriMet transit tax, covering the Portland tri-county metro area, is 0.8237 percent of net self-employment earnings for services performed within the district.16TriMet. Payroll and Self-Employment Tax Information Oregon also imposes a statewide transit tax of 0.1 percent on wages, though self-employment income is not subject to the statewide version.17Oregon Department of Revenue. Statewide Transit Tax The Lane Transit District in the Eugene area has its own separate rate for employers in that region.
