State Revenue

Revenue from taxes comprises almost all of the state revenues deposited in the state general fund, but slightly less than 50 percent of all revenues received by the state. Other sources of revenue include both federal and other grants, license and permit fees, charges for services, and borrowing. Washington relies on the sales tax, the business and occupation (B&O) tax, and property tax. Unlike most states, Washington does not have either a personal or corporate net income tax.
