McKenna challenges WA income tax constitutionality

Former Attorney General Rob McKenna and legal heavyweights launch their constitutional challenge Thursday against Washington's new 9.9% income tax on millionaire earners. The lawsuit targets Senate Bill 6346, signed by Governor Ferguson in March, which ends Washington's status as one of few states without individual income tax. Supporters welcome the legal fight, expecting it to reach the state Supreme Court for definitive ruling on progressive taxation. Collections begin in 2029 if the law survives court challenges. https://www.clarkcountytoday.com/news/court-battle-set-to-begin-over-was-new-income-tax/ #WashingtonState #IncomeTax #LegalChallenge #Politics #TaxLaw #Constitution #ClarkCounty #News
