Concerning broadcasters.

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.
