Business and Occupation Tax.
Washington's major business tax is the business and occupation (B&O) tax.  The B&O tax is imposed on the gross receipts of business activities conducted within the state, without any deduction for the costs of doing business.  Businesses must pay the B&O tax even though they may not have any profits or may be operating at a loss.
 
A taxpayer may have more than one B&O tax rate, depending on the types of activities conducted.  Major B&O tax rates are 0.471 percent for retailing; 0.484 percent for manufacturing, wholesaling, and extracting; and 1.5 percent (businesses with taxable income of less than $1 million) or 1.75 percent (businesses with taxable income of $1 million or more) for services and for activities not classified elsewhere.  Several preferential rates also apply to specific business activities.
 
In addition, a taxpayer may be eligible to utilize other tax preferences, including credits and deductions, to reduce their tax liability.  For example, a taxpayer engaging in activities subject to different B&O tax rates may be eligible for a Multiple Activities Tax Credit.  A taxpayer may also be eligible for a small business credit that will either eliminate or reduce their B&O tax liability.  In general, the credit is $70 per month for service businesses and $35 per month for all other businesses, multiplied by the number of months in the reporting period.  The amount of the credit available phases out based on the business's gross receipts.
 
A business does not have to file an annual B&O tax return if the business does not owe other taxes or fees to the Department of Revenue (DOR) and has annual gross proceeds of sales, gross income, or value of products for all B&O tax classifications of less than $28,000 per year, or less than $46,667 if at least 50 percent of its taxable income is from services or activities not classified elsewhere.
 
Tax Preferences.
State law provides for a range of tax preferences that confer reduced tax liability upon a designated class of taxpayer.  Tax preferences include tax exclusions, deductions, exemptions, preferential tax rates, deferrals, and credits.  Currently, Washington has over 650 tax preferences, including a variety of sales and use tax exemptions.  Legislation that establishes or expands a tax preference must include a Tax Preference Performance Statement that identifies the public policy objective of the preference, as well as specific metrics that the Joint Legislative Audit and Review Committee (JLARC) can use to evaluate the effectiveness of the preference.  All new tax preferences automatically expire after 10 years unless an alternative expiration date is provided.
 
Health Benefit Exchange Tax Exemption.
In 2011 the Washington Health Benefit Exchange (Exchange) was established by the Legislature as a state-based marketplace for consumers to compare and obtain health insurance plans that meet federal standards.  It also connects qualifying residents to federal subsidies that lower their healthcare costs.

The Exchange is a public-private partnership and is funded through legislative appropriations from the Health Benefit Exchange Account, federal funds, and the State General Fund.  In 2013 the Legislature exempted the Exchange's funding from B&O taxes.  The tax preference will expire on July 1, 2023.

The B&O tax exemption for the Exchange is made permanent.
