The Washington State Tax Structure Work Group officially ended on June 30th of this year. Although the group was slated to produce a final report by December 2024, the legislature did not provide funding for the group to continue. The final report was made public this month. 

TSWG was established in 2017 to “identify options to make Washington’s tax code more equitable, fair, adequate, stable, and transparent.” The mission was expanded in 2019 to include analyzing and facilitating statewide public discussion about Washington’s tax structure. This included updating previous research on state tax structure changes, making legislative recommendations, and providing the previously mentioned final report. 

In 2019 legislative proviso directed the TSWG to examine tax principles in their modeling. They included several progressive tax principles, including vertical equity. This would mean creating tax rates based on the ability to pay rather than on a flat basis as codified in Washington State’s Constitution. 

TSWG Tax Principles

Under those tax principles, the group also examined tax modeling for alternative tax options for both business and personal taxes. The group reviewed a value-added tax, margin tax, and corporate income/net receipts tax for businesses. They also examined personal income tax and alternative property tax for households. 

As mentioned, the TSWG was tasked with public engagement on these various potential changes. The group held virtual forums throughout the state. Feedback on changes to taxes provided an interesting insight into public sentiment on taxes. Two tax reduction options more supported than raised concerns, and the proposal for a flat income tax also solicited more opposition than support. Per the report: 

The report’s conclusion reviews the tax concepts and proposed legislative ideas from the 2023 session, including the Margin Tax Bill SB 5482 and Property Tax Revenue Growth Limit SB 5618 and HB 1670. These bills did not pass in the 2023 session.
