The plain facts
These are the same numbers the Estate Explorer on this site works with.
The line sits high
The Washington exclusion is $3 million per person who dies. Estates under it owe no Washington estate tax.
Above the line
Rates climb in steps from 10 to 20 percent. They apply to the part above the line, not the whole estate.
One line per spouse
A spouse who dies first does not pass the unused part along. Each spouse holds a separate $3 million line. Lawyers call this no portability.
The federal line is far higher
The federal exemption is $15 million per person. A family can owe Washington tax and owe no federal tax at all.
Where coverage meets the tax
Two facts decide it: what the estate holds, and who owns the policy.
Owned coverage joins the estate
Coverage a person owns on their own life counts toward their estate total. For most families the total stays under the line, and it changes nothing.
The benefit itself is income-tax-free
Death benefits reach the people named on the policy free of income tax. Estate tax and income tax are separate systems.
Cash, so nothing must be sold
Some families hold coverage so a tax bill can be paid in cash. The house does not have to be sold to pay it.
