What are the Washington estate tax rates?
Graduated rates from 10 percent to a top rate of 20 percent on the Washington taxable estate above $9,000,000, for deaths on or after July 1, 2026, under RCW 83.100.040. Deaths between July 1, 2025 and June 30, 2026 fell under a temporary schedule that topped out at 35 percent, and the exclusion for deaths in the first half of 2026 was $3,076,000, so the date of death matters as much as the values.
Does Washington use court-appointed probate appraisers?
No. RCW 11.44.015 places the duty on the personal representative to prepare a true inventory and appraisement within three months of appointment, unless the court grants more time, and names no roster of court appraisers. Professional appraisals are how personal representatives support the values they swear to, which is the role our date-of-death reports play in Washington probates.
