Washington's Long Sordid Saga With Income Taxes

Posted By: Joe Fain Advocacy, CEO Message,
Many efforts to enact an income tax through legislative or voter action have failed.
Two were vetoed by the Governor in 1931, five were overturned by the Washington Supreme Court, and nine were rejected by voters.
The only proposal ever approved at the ballot, Initiative 69 in 1932, was ultimately ruled unconstitutional by the Washington State Supreme Court.
