Oregon Sales Tax

Oregon has never had a general sales tax, and it is not for lack of trying. Proposals have gone to voters repeatedly since the 1930s and been defeated every time, often by large margins. It has become something close to a settled part of the state's political identity.

The consequence is that income tax carries the load. Oregon's income tax starts at 4.75% from the first dollar — higher than the top rate in several states — precisely because there is no consumption tax sharing the burden.

Washington residents crossing into Portland to make large purchases is a well-documented pattern, and Washington has at times restricted its sales tax exemption for Oregon residents in response.

The reverse trip is less appealing than it looks: an Oregon resident working in Washington still pays Oregon income tax as a resident, so Washington's lack of an income tax provides them nothing. The border rewards living in Washington and shopping in Oregon — not the other way round.

Oregon is one of five states with no statewide sales tax, alongside Alaska, Delaware, Montana, New Hampshire and Oregon. Unlike Alaska, it also prohibits local sales taxes, so there is genuinely nothing added to a purchase anywhere in the state. That makes Oregon a destination for larger purchases from neighbouring states.

Ranked 50 of 50 by average combined rate, Oregon sits below the national population-weighted average of 7.53% by 7.53 percentage points. Oregon also levies income tax, so sales tax is one part of the picture rather than the whole of it.

What gets taxed matters as much as the rate. States differ considerably on groceries, prescription drugs, clothing and services, and those exemptions can affect a household's real burden more than a percentage point on the headline rate. Check your state revenue department for the current exemption list before relying on any calculation for a business filing.
