Washington Estate Tax and Inheritance Tax: Know the Difference

The Role of Estate Tax in Washington State

Washington State imposes an estate tax on estates exceeding a certain threshold. This means that if the total value of your estate exceeds the exemption amount set by the state, your estate may be subject to paying estate taxes which will reduce the amount of money and assets that ultimately are distributed to your heirs.

Exemption Thresholds and Tax Rates

Washington’s estate-tax exclusion and rates depend on the date of death, not the date the estate is settled. For deaths from July 1 through December 31, 2026, the applicable exclusion is $3 million, and graduated rates range from 10% to 20% of the Washington taxable estate. Different rules apply to earlier dates of death:

• January 1–June 30, 2025: $2,193,000 exclusion; rates of 10%–20%.
• July 1–December 31, 2025: $3,000,000 exclusion; rates of 10%–35%.
• January 1–June 30, 2026: $3,076,000 exclusion; rates of 10%–35%.
• July 1–December 31, 2026: $3,000,000 exclusion; rates of 10%–20%.

These graduated rates apply to the Washington taxable estate after allowable deductions and the applicable exclusion. They are not a flat tax on the entire estate. Check the Washington Department of Revenue’s current tables for the rules applicable to the date of death.

Does An Estate Need To File If No Washington Estate Tax Is Owed?

A return may still be required even when deductions eliminate the tax. Generally, Washington’s filing test uses the gross estate and applies when it equals or exceeds the applicable exclusion. A qualifying family residence passing to a surviving spouse can affect the filing requirement, subject to statutory conditions.

This is a filing exception, not a blanket deduction for every home. Some elections can still require a return.

Washington’s return and tax payment are generally due nine months after death. An extension to file does not extend the payment deadline.

Strategies for Minimizing Estate Taxes

1. Lifetime Gifting

One effective strategy for minimizing estate taxes is to engage in lifetime gifting. By gifting assets to your heirs during your lifetime, you can reduce the overall value of your estate, thus potentially lowering the amount subject to estate tax upon your passing. However, it’s essential to consider the gift tax implications and ensure compliance with both Washington State and the IRS regulations.

2. Establishing Trusts

Trust and marital-deduction planning should be evaluated for the couple’s circumstances. Avoiding tax at the first death is not the same as eliminating tax when the surviving spouse dies. Sources: Washington DOR: estate tax FAQ; IRS: estate tax FAQs. An attorney can review how the plan addresses each spouse’s Washington exclusion and any separate federal estate-tax requirements.

Tax planning and probate planning should be considered separately; neither result should be assumed from the existence of a trust alone.

3. Washington Does Not Allow Estate Tax Portability

Washington does not allow a surviving spouse to use a deceased spouse’s unused Washington estate tax exclusion through portability. Federal estate tax portability is a separate rule and does not create portability for Washington estate tax. Sources: Washington DOR: estate tax FAQ; IRS: estate tax portability. Married couples should have their Washington and federal planning reviewed separately.

Importance of Advance Planning

Advance planning can help you understand Washington estate tax and federal estate tax obligations. An estate planning attorney can review available strategies in light of your assets, family circumstances and goals.

• Remember this: You can never get your estate planning done too early…..you can only wait until it is too late. If you wait too long, you and your family will be stuck with whatever the legislature provides.

Conclusion

Washington has an estate tax, not an inheritance tax, and its estate tax rules differ from federal rules. Review the law applicable to the date of death and seek advice before relying on an exclusion, tax rate or planning strategy.
