Oregon levies a graduated personal income tax and taxes corporations through a corporate income and excise tax, but it is one of the few states with no general statewide sales or use tax. Offsetting the absence of a sales tax, Oregon imposes a separate Corporate Activity Tax (CAT) measured on commercial activity in the state, and it runs a state transient lodging tax that, together with local lodging taxes, applies directly to short-term rentals, campgrounds, RV parks, and hotels. Most of these taxes are administered by the Oregon Department of Revenue, with the Secretary of State handling entity registration.

Oregon levies a graduated personal income tax and taxes corporations through a corporate income and excise tax, but it is one of the few states with no general statewide sales or use tax. Offsetting the absence of a sales tax, Oregon imposes a separate Corporate Activity Tax (CAT) measured on commercial activity in the state, and it runs a state transient lodging tax that, together with local lodging taxes, applies directly to short-term rentals, campgrounds, RV parks, and hotels. Most of these taxes are administered by the Oregon Department of Revenue, with the Secretary of State handling entity registration.
Oregon imposes a graduated personal income tax on residents and on nonresidents with Oregon-source income, and the state's income tax is one of the heavier individual tax regimes in the country precisely because there is no sales tax to share the load. Since most owner-operated businesses are pass-through entities, profits from sole proprietorships, partnerships, S corporations, and most LLCs flow through to the owners and are taxed on their individual Oregon returns rather than at the business level. Oregon generally starts from federal taxable income but applies its own additions, subtractions, and credits, so owners deciding how to draw salary versus distributions or when to recognize gains should model the Oregon result separately from the federal one. Owners living in or operating around Portland should also account for local income taxes layered on top of the state tax.
C corporations doing business in Oregon pay the corporate income and excise tax on income apportioned to the state, subject to a minimum tax that applies even when a corporation shows little or no net income. Separately, Oregon imposes the Corporate Activity Tax (CAT), a commercial-activity tax based on a business's Oregon-sourced gross receipts above a registration threshold, which applies broadly across entity types rather than only to corporations; because the CAT is measured on receipts rather than profit, it can reach businesses that owe little or no income tax, so it must be tracked on its own. Oregon also offers a pass-through entity elective (PTE-E) tax that lets eligible partnerships and S corporations pay Oregon tax at the entity level, a workaround that can preserve a federal deduction for owners affected by the federal SALT cap, with a corresponding credit on the owners' Oregon returns; the right combination of CAT exposure, income tax, and the PTE-E election should be confirmed against current Department of Revenue guidance.
Oregon has no general statewide sales or use tax, so most businesses selling goods or services within the state do not collect sales tax from customers and do not register for or remit an Oregon sales tax. This also means the economic-nexus and marketplace-facilitator rules that drive remote-seller sales-tax compliance in most states generally do not create an Oregon sales-tax obligation, although an Oregon-based seller shipping into other states can still trigger nexus and collection duties under those states' rules. The nexus concept that matters most in Oregon runs the other direction: out-of-state and in-state businesses with enough Oregon commercial activity can owe the Corporate Activity Tax and the corporate income tax, so the analysis is about income and CAT exposure rather than sales-tax registration.
Even without a general sales tax, Oregon taxes overnight stays through a state transient lodging tax that applies to hotels, motels, short-term rentals, campgrounds, RV parks, and similar accommodations rented for short stays. On top of the state tax, most counties and many cities levy their own local transient lodging or room taxes, so a single property can owe both a state and one or more local lodging taxes depending on its exact jurisdiction. Operators are generally required to register, collect the applicable lodging taxes from guests, and remit them on the schedule the state or locality assigns; hosts using online platforms should verify precisely which of these taxes the marketplace collects on their behalf, because platform collection often covers the state transient lodging tax but may not cover every local room tax.
Most Oregon tax accounts, including income tax withholding, the corporate income and excise tax, the Corporate Activity Tax, and the state transient lodging tax, are registered and managed through the Oregon Department of Revenue's Revenue Online system, while entity formation runs through the Secretary of State's business registry. Returns follow their own cycles: income and corporate returns are annual with estimated payments for taxpayers above the state's thresholds, the CAT has its own annual return and quarterly estimate structure for businesses over the threshold, and lodging-tax returns are filed on a recurring cadence set by the state and by each local jurisdiction. Because there is no sales tax to reconcile, ongoing compliance for owner-operated Oregon businesses tends to concentrate in payroll withholding, CAT tracking for any business with meaningful Oregon receipts, and clean documentation of state and local lodging-tax collections, all of which the Department of Revenue can examine on audit.
Oregon's no-sales-tax status is a genuine pricing advantage for retail and e-commerce, but it is offset by a high personal income tax and the Corporate Activity Tax, which together mean Oregon is not a low-tax state for profitable owner-operators despite the absence of sales tax. For hospitality clients, the most common compliance gap is the patchwork of local transient lodging taxes layered on the state lodging tax, since rates, registration, and remittance vary city by city and county by county, and marketplace collection rarely covers all of them uniformly. Treating each property's specific city and county as its own lodging-tax question, and tracking Corporate Activity Tax exposure separately from income tax, is what keeps multi-property and multi-entity Oregon operators clean.
Oregon owner-operators work with Parikh Financial because the state's no-sales-tax surface hides real complexity: a high personal income tax, the receipts-based Corporate Activity Tax, the PTE-E election, and a patchwork of state and local transient lodging taxes for hospitality clients. We handle the bookkeeping, lodging-tax registration and remittance for STR, campground, and hotel operators, CAT and multi-state nexus tracking, and the entity-structure and PTE-E decisions that determine how much Oregon tax owners actually pay.
