Budget & Taxes

SB 5457 modifies Washington State's business tax for radio and television broadcasters. It requires broadcasters to calculate tax based on gross income minus specific advertising revenues, directly affecting FCC-licensed radio and TV stations operating in Washington. The key provision allows broadcasters to exclude national/regional ad revenue either through a standard deduction (based on U.S. Census data) or by itemizing out-of-state audience revenue using defined signal strength contours. This change, effective July 2025, adjusts how taxable income is calculated for broadcasters under the existing 0.484% business tax rate.
