Washington’s estate tax traps middle-class families

The state of Washington has no income tax, but that doesn’t mean it ignores estates when someone dies. In fact, it has one of the most aggressive estate tax systems in the country—and recent changes have made it even more unpredictable. The exemption threshold, which determines who pays, was frozen at $3 million this summer, while inflation keeps pushing more families over the line without them realizing it.

The catch? Washington’s estate tax doesn’t just target the ultra-wealthy. A couple in Spokane with a $650,000 home paid off, $2.5 million in retirement and brokerage accounts, and a life insurance policy could easily exceed the exemption—even if neither spouse ever considered themselves rich. That’s because the tax applies to far more than cash in the bank. It includes:

• The value of a home, even if the mortgage is gone.
• Retirement accounts (IRAs, 401(k)s), which can be taxed twice, once in estate tax, again when heirs withdraw funds.
• Brokerage accounts.
• The death benefit from life insurance, a detail many overlook.

Washington also doesn’t allow portability between spouses, unlike the federal system. If one spouse dies, the surviving spouse doesn’t automatically inherit the unused exemption. Without planning, couples often end up with just one exemption to cover both estates, leaving more exposed to taxes.

This summer, lawmakers made two conflicting moves. They lowered the top estate tax rate from 35% to 20%, which helps larger estates. But they also reset the exemption to $3 million and froze it, no annual inflation adjustments. That means the threshold stays flat while asset values rise. For deaths before July 1, 2026, the exemption was $3.076 million, adjusted for inflation. After that date, it dropped to $3 million and won’t budge.

The freeze creates a mismatch. A couple who comfortably cleared the old exemption in 2025 might find themselves liable in 2027, just because their retirement accounts grew or home values rose. The tax isn’t just about wealth, it’s about timing.

For many families, the most frustrating part is how easily this can be avoided. Strategies like a credit shelter trust can preserve both spousal exemptions, even without portability. An irrevocable life insurance trust removes the death benefit from the taxable estate. Other approaches, like gifting during life or making qualified charitable distributions from IRAs (tax-free for retirees 70½ and older), reduce the estate’s value before taxes kick in. But these require action before it’s too late. Once assets exceed the threshold, the tax is locked in, and there’s no retroactive fix.

The frozen exemption isn’t a bug; it’s a deliberate choice. Lawmakers designed it to gradually pull more estates into the tax net over time. For families near the line, the message is clear: the longer they wait to plan, the harder it becomes. The tax doesn’t care if you felt wealthy. It only cares about the numbers on the day you die.

An estate attorney or fiduciary adviser can walk through the options, but the key takeaway is simple: Washington’s estate tax doesn’t discriminate. It catches people who assume their assets are safe, until it’s too late.
