A utility tax is a tax on public service businesses, including businesses that engage in transportation, communications, and the supply of energy, natural gas, and water. The tax may exist in lieu of a business and occupation (B&O) tax. Such taxes are governed by state laws, which vary by state. In some instances, a portion, however, provides financial assistance to local governments for maintenance of public works facilities.
The following is an example of a state law providing for utility taxes:
"Public utility tax imposed -- Additional tax imposed -- Deposit of
moneys.
An additional tax is imposed equal to the rate specified in RCW 82.02.030 multiplied by the tax payable under subsection (1) of this section.
Twenty percent of the moneys collected under subsection (1) of this section on water distribution businesses and sixty percent of the moneys collected under subsection (1) of this section on sewerage collection businesses shall be deposited in the public works assistance account created in RCW 43.155.050."
