Does a Trust Avoid Washington State Estate Tax?

Does a trust avoid Washington state estate tax? It depends entirely on the type of trust. A revocable living trust will not reduce your Washington estate tax by a dollar, because the state counts those assets in your gross estate exactly as if you owned them outright.¹ A bypass trust for married couples and certain irrevocable trusts, on the other hand, can meaningfully reduce or even eliminate the tax. The tradeoff is control: the trusts that actually cut the tax bill are the ones you cannot undo.

Why a Revocable Living Trust Does Not Reduce the Tax

A revocable living trust is useful. It keeps your assets out of probate, the court-supervised process for validating a will and distributing property, which can save your family time and expense.² What it does not do is shrink your taxable estate.

Washington explicitly includes assets held in a revocable trust when calculating the gross estate.¹ The reasoning is simple. You can amend or revoke the trust and pull the assets back at any time, so you still effectively own them. Retitling a $4 million estate into a revocable trust does not change the estate tax result.

The one real tax benefit a revocable trust preserves is the step-up in basis. Assets in the trust receive a new cost basis equal to fair market value at your death, just like assets held outright, so heirs do not owe capital gains tax on appreciation that happened during your life.³ That matters when you start comparing revocable and irrevocable options below.

The Exclusion Amount That Trips People Up

For deaths in 2026, Washington’s exclusion is $3,076,000. Only the value above that threshold is taxed, and the exclusion adjusts each year for inflation based on the Seattle-area consumer price index.¹ The rates are graduated: 10% at the bottom of the taxable amount and climbing to 35% on the portion over $9,000,000.⁴

Compare that to the federal exemption of $15,000,000 per person in 2026 following passage of the One, Big, Beautiful Bill.⁵ A married couple with a combined $7 million estate owes zero federal estate tax but can face a serious Washington bill. That gap between the federal and state thresholds is where trust planning does most of its work. In the Seattle metro area, home equity, retirement accounts, and life insurance can push a household above $3,076,000 more easily than most people expect.

The Bypass Trust: The Key Move for Married Couples

The most important fact for married Washington residents is this: Washington does not allow portability of its state estate tax exemption. Each estate gets its own exclusion tied to the decedent’s date of death, and any unused portion disappears.¹

The federal system works differently. A surviving spouse can inherit the deceased spouse’s unused federal exemption by filing a portability election on a timely Form 706.⁶ Washington has no equivalent. If the first spouse leaves everything outright to the survivor, that first $3,076,000 exemption is simply lost. When the survivor later dies with the combined estate, only one exemption shelters it.

A bypass trust, sometimes called a credit shelter trust or AB trust, is built for exactly this problem. When the first spouse dies, assets up to the exemption amount fund an irrevocable trust for the benefit of the surviving spouse and children. Depending on the drafting, the survivor can typically receive income and access principal for health, education, maintenance, and support. Because the assets sit in trust rather than in the survivor’s name, they are not part of the survivor’s taxable estate at the second death.

Run the numbers on a $6 million estate. With no trust planning, the surviving spouse dies holding the full $6 million, one $3,076,000 exemption applies, and Washington estate tax falls on roughly $2,924,000. With a properly funded bypass trust, the first spouse’s $3,076,000 exemption shelters the trust and the surviving spouse’s own $3,076,000 exemption shelters the rest. The result is zero Washington estate tax on the same $6 million.

Washington does allow a marital deduction for assets passing outright to a surviving spouse, similar to the unlimited federal marital deduction.¹⁷ But the marital deduction is not a tax saving. It is a deferral that pushes the entire bill to the second death, which is precisely what the bypass trust is designed to solve.

Irrevocable Trusts That Actually Shrink the Taxable Estate

Beyond the bypass trust, several irrevocable structures can move specific assets outside your Washington taxable estate. The common thread: you give up ownership and control for good. Once assets are genuinely outside your estate, Washington does not count them.¹

Irrevocable Life Insurance Trust (ILIT)

An ILIT owns a life insurance policy on your life. At your death, the proceeds pay to the trust rather than your estate, so they escape Washington estate tax. For a $2 million policy, the state-level savings alone can top $200,000.

Timing matters. If you transfer an existing policy to an ILIT and die within three years, the full death benefit is pulled back into your gross estate.¹ When feasible, have the ILIT purchase the policy directly so there is no transfer to trigger the three-year lookback.

Grantor Retained Annuity Trust (GRAT)

A GRAT lets you move assets into an irrevocable trust while keeping the right to fixed annuity payments for a set term. Whatever remains at the end of the term passes to your beneficiaries free of additional gift or estate tax. The strategy pays off when the trust assets grow faster than the IRS’s Section 7520 rate, because the excess growth passes tax-free.⁸ In early 2026, that rate sits around 4.6% to 4.8%.

If you die during the annuity term, the trust assets get pulled back into your taxable estate. GRATs work best for younger grantors or shorter terms.

Charitable Remainder Trust (CRT)

A CRT pays you an income stream for life or a set term, and whatever remains goes to a qualified charity. You get a partial charitable deduction based on the present value of the charity’s future interest, which reduces both your income tax during life and the value of your taxable estate at death.⁹ For charitably inclined residents, a CRT can lower the Washington estate tax bill and support a cause in one structure.

The Step-Up in Basis Tradeoff

Every irrevocable transfer carries a hidden cost that is easy to miss. Assets that leave your estate generally do not receive a step-up in basis at death.³ Beneficiaries inherit your original cost basis and owe capital gains tax on the appreciation when they sell.

Whether that tradeoff is worth it depends on the numbers. Washington’s top estate tax rate of 35% on the largest estates usually exceeds the capital gains rate a beneficiary would pay. For estates near the exemption, though, the estate tax savings can be modest while the lost basis step-up creates a larger capital gains bill later. Getting this calculation wrong in either direction costs real money, which is why irrevocable trust decisions deserve modeling before signing.

Assets in a revocable trust do get the full step-up because they remain in your gross estate.³ Bypass trust assets typically also receive a step-up at the first spouse’s death, because they are included in that spouse’s taxable estate before funding the trust.

Washington is a community property state, which adds a further wrinkle for spouses. Both halves of community property generally receive a stepped-up basis at the first death, not just the deceased spouse’s half. A good plan preserves that community property treatment while still capturing bypass trust benefits.

Lifetime Gifting Alongside the Trust

Gifts made during your life reduce your taxable estate. For Washington estate tax purposes, outright gifts given before death are generally not taxable at the state level.¹

The federal annual gift tax exclusion for 2026 is $19,000 per recipient.¹⁰ Married couples can give $38,000 per recipient without filing a gift tax return. A couple with three children and six grandchildren could move $342,000 out of the estate each year without touching their lifetime exemption. Over a decade, that is more than $3 million removed from the Washington taxable estate.

One state-specific caveat: any federal gift tax actually paid within three years of death is added back to the Washington estate as an asset.¹ Given the $15 million federal exemption, that rarely bites, but it exists.

If You Own a Family Business

Washington offers a separate deduction for qualified family-owned business interests (QFOBI) that can shelter up to $3,076,000 of additional estate value in 2026.¹¹ The business interests must be more than 50% of the taxable estate, the family must have owned and materially participated for at least five of the eight years before death, and the total value of the interests cannot exceed $6 million.¹²

Combined with the standard exclusion, the QFOBI deduction can shelter more than $6 million from Washington estate tax. If a business is a major part of your estate, coordinate your trust structure with the deduction. It is possible to design a trust that inadvertently disqualifies the estate from claiming it.

Which Trust Fits Which Situation

A revocable trust handles probate and preserves the basis step-up but does not reduce Washington estate tax. A bypass trust is close to essential for married couples above the exemption because Washington has no portability. ILITs, GRATs, and CRTs can each remove targeted assets from the taxable estate, at the cost of losing the basis step-up on those assets and giving up control. And annual gifting quietly shrinks the estate on its own without any trust at all.

The right combination depends on the size of the estate, marital status, the composition of the assets, and how much control you are willing to give up now to reduce what your heirs pay later. Modeling the numbers before signing any irrevocable document is the part that separates a plan that works from one that only looked like it did.
