Washington State Estate Tax
Washington State has its own "stand alone" estate tax.
Washington State estate tax has the following deductions:
- $2 million statutory deduction (RCW § 83.100.020(13))
- Deduction for property used for qualifying farm purposes (RCW § 83.100.046)
- Full Marital Deduction (RCW § 83.100.047)
The marginal Washington estate tax rates range from 10% to 20% and those brackets are shown below. "The Washington Taxable Estate" is the gross estate less applicable deductions (e.g. $2 million statutory + any applicable marital or farm deduction).
