Tax Structure

Idaho and Washington take different approaches to corporate and personal taxes. In Idaho, low corporate and personal income tax rates provide revenues to operate the state. Washington bases its business and occupation tax on gross revenues and imposes no personal income tax.

Other benefits produce additional balance sheet flexibility. Investment tax credits, community block and rural business development grants, tax increment financing, and community empowerment zone credits are among them.
