As reported on May 13, 2025, several changes to the Washington state tax laws were passed by lawmakers and delivered to the desk of Governor Ferguson in late April, awaiting his signature to make them law. In the aggregate, these changes create what is likely the largest historical increase in taxes the state has ever seen. While there was some speculation that the governor would not sign all of the bills into law, especially since they had been sitting on his desk for more than three weeks, that speculation is no longer. Governor Ferguson signed these bills into law on May 20, 2025.
