From the Seattle Times – A 2018 study by the Institute on Taxation and Economic Policy found that the poorest families in Washington paid about 18% of their income in state and local taxes, while the richest families paid about 3% of their income in state and local taxes, the largest disparity in the country.
In 2008, Governor Christine Gregoire signed into law, the Working Families Tax Credit, in an effort to give modest money back to the low income residents in Washington state who pay a greater portion of their income in sales taxes. Unfortunately, the Legislature never saw fit to FUND the tax credit…until 2021, that is. This year, for the first time since 2008, low income residents can apply for the tax credit!
Who’s eligible for the new tax credit?
Low income Washington State Residents. Those aged 18-25 without children are ineligible, even if they meet the income requirement shown below.
