MAJOR CHANGES TO WASHINGTON ESTATE TAX RATES AND EXEMPTIONS
Washington State has enacted new legislation that significantly changes estate tax rates and exemption amounts, effective over the next year. In 2025, prior to the latest law, the top estate tax rate was set to increase to 35%, and the estate tax exemption amount was scheduled to be indexed for inflation, resulting in a $3,000,000 exemption from July 1 to December 31, 2025. For deaths occurring between January 1 and June 30, 2026, the exemption increased slightly to $3,076,000 due to inflation adjustments.
In response to concerns that the higher rates were causing wealthy
residents to leave the state, lawmakers passed a new bill (effective June 11, 2026) that reinstates the previous estate tax rate schedule, lowering the top rate from 35% back to 20% as of July 1, 2026. The new law also freezes the estate tax exemption at $3,000,000 for estates of decedents dying on or after July 1, 2026, with no future adjustments for inflation. Because the estate tax rates and exemption amounts change mid-year in both 2025 and 2026, the date of death will greatly impact estate tax outcomes.
