The Greater Portland region straddles the mighty Columbia River and includes the states of Oregon and Washington. The region's bi-state composition gives local businesses a distinct advantage: the opportunity to consider two tax codes to determine a best fit.
In Oregon, corporate business tax accounts for less than 3.5 percent of the gross state product, compared with 4.7 percent for California and 4.9 percent for Texas.
Businesses will find that both Oregon and Washington have designed their tax codes to attract and retain companies. As a result, Oregon and Washington state tax structures rank in the top fifth of the nation for business-friendly tax structure.
