Washington Democratic Gov. Bob Ferguson on Monday signed historic laws creating an earnings tax, saying it’s a crucial step towards making the state’s system of taxation much less regressive.
“Thank you, thank you, thank you. We did it everybody,” Ferguson turned and exclaimed to the throng of lawmakers, union members and pro-tax advocates who squeezed into the state reception room on the Capitol to witness the signing of Senate Bill 6346.

But it should clear formidable hurdles earlier than taking impact.

Rob McKenna, a former state lawyer normal and 2012 Republican candidate for Washington governor, will lead the litigation.

Also Monday, Brian Heywood, founding father of the conservative political committee Let’s Go Washington, filed a referendum to offer voters a likelihood to repeal the legislation this fall.
However, as a result of the brand new legislation incorporates a so-called “necessity clause” stopping a referendum, the Secretary of State’s Office will formally reject the submitting by noon Tuesday. Once that occurs, Heywood may sue to take away the language and permit such a poll challenge.
If this maneuver is unsuccessful, Heywood has mentioned an initiative to derail the legislation can be pursued both this yr or subsequent.

“We’re going to begin to right a historic wrong that has plagued our state for nearly 100 years and made our tax system one of the worst and most regressive in the entire country,” Pedersen mentioned. “I hope and believe that one day we’re going to look back on this day as the day when things really started to change for us, when our state and our system started to get more fair.”
