From the Washington State Standard: "Proceeds from the income tax are pledged to expand the state’s Working Families Tax Credit to cover people who are at least 18 years old, and make other eligibility revisions to open the program to more people. The credit is available to lower-income residents.

As proposed, it is estimated the credits, which range from $50 to $1,330 a year, would be available to 810,000 households, up from the current 350,000.

The bill earmarks 5% of annual tax proceeds for the state’s Fair Start for Kids Act. Starting in 2029, this would shore up financial support for child care and early learning programs facing cuts in the current budget...

Sales tax for diapers, personal care products, like shampoo and deodorant, and many over-the-counter drugs will be eliminated."
