Washington has no income tax, which leads many people to assume it is a low-tax state for estates as well. The opposite is true. Washington imposes one of the most significant state estate taxes in the country, it does not allow portability between spouses, and its exclusion amount and rate schedule were changed twice during 2026. A Washington couple can lose an entire exclusion — worth hundreds of thousands of dollars in tax — simply by leaving everything to each other outright.
Washington is also a community property state with a distinctive and very efficient probate system, a homestead exemption tied to county median home prices, and a well-developed dispute resolution statute. The Holmes Law helps Washington residents and out-of-state owners of Washington property build plans that address the state estate tax, use Washington’s probate advantages, and put the right people in charge.
The Washington Estate Tax After the 2026 Changes
Washington’s estate tax rules moved twice in 2026, and a great deal of published commentary is out of date. Here is where the law actually stands.
Senate Bill 5813 raised the applicable exclusion amount and steepened the rate schedule. Engrossed Substitute Bill 6347, enacted as chapter 209 of the Laws of 2026 and effective June 11, 2026, reversed part of that change. The result is two different regimes within the same calendar year, determined by the decedent’s date of death:
- Deaths from January 1, 2026 through June 30, 2026 — applicable exclusion amount of $3,076,000, with marginal rates running from 10% up to 35%.
- Deaths from July 1, 2026 through December 31, 2026 — applicable exclusion amount of $3,000,000, with the rate schedule reverting to a range of 10% to 20%.
Annual inflation indexing of the exclusion begins with calendar year 2027. The 2027 figure has not been published, and no one should be planning against a specific projected number.
Two mechanical points matter as much as the headline figures. First, the filing obligation under RCW 83.100.050(1) is triggered by the gross estate meeting the exclusion amount — before deductions for debts, expenses, or the marital deduction. An estate that owes no tax may still be required to file a Washington estate tax return, and a return that is never filed can leave the matter open indefinitely. Second, the Washington gross estate includes the full death benefit of life insurance the decedent owned, retirement account balances, and the decedent’s interest in real property — items people routinely leave out of a back-of-the-envelope estimate. A Seattle-area couple with a long-held home, two retirement accounts, and a life insurance policy can be well over the exclusion without any sense of being wealthy.
Washington Has No Portability — and That Changes the Plan
Federal law lets a surviving spouse elect to use the deceased spouse’s unused exclusion. Washington does not. If the first spouse to die leaves everything outright to the survivor, that spouse’s Washington exclusion is lost permanently.
The standard remedy is a credit shelter or bypass trust. On the first death, an amount up to the Washington exclusion is directed into an irrevocable trust that can support the surviving spouse for life but is not included in the survivor’s taxable estate. Both exclusions are preserved, and the combined shelter roughly doubles.
Washington also permits a state-only QTIP election under RCW 83.100.047 and WAC 458-57-115. This allows an estate to qualify property for the Washington marital deduction independently of the federal election — an essential coordinating tool given the very large gap between the federal exemption and Washington’s exclusion. A well-drafted Washington plan usually builds in the flexibility to decide at the first death, based on the law and the family’s circumstances at that time, how much to shelter and how much to defer.
As in every state with a credit shelter structure, the plan only works if assets are available to fund it. Washington couples who hold everything as community property with right of survivorship, or in joint accounts, often find that everything has already passed to the survivor by operation of law before the trust can be funded. Reviewing title and beneficiary designations is not a clerical afterthought — it is the step that determines whether the tax planning functions.
Deductions for Farms and Family Businesses
Washington provides relief for two categories of estate that would otherwise be forced into a sale to pay the tax. Qualifying farm property used for farming purposes may be deducted from the Washington taxable estate, and a separate deduction is available for qualified family-owned business interests. Both come with detailed eligibility conditions concerning ownership, material participation, and what happens if the property is later disposed of. For a Washington family whose wealth is concentrated in land or an operating business, confirming eligibility well in advance is one of the highest-value planning steps available.
Washington Probate Is Genuinely Efficient
Washington’s probate system is among the best designed in the country, and this is the reason a great many Washington families use a will rather than a living trust.
The key is nonintervention powers under chapter 11.68 RCW. Where the estate is solvent and the will requests it, the court enters an order of solvency granting the personal representative authority to administer the estate without further court involvement — no court approval to sell the house, no court approval to pay claims, no interim accountings. Administration proceeds largely as a private matter, with a creditor notice period and a declaration of completion at the end. Washington also does not impose a percentage-based statutory fee; compensation is on a reasonable basis.
Washington’s Trust and Estate Dispute Resolution Act, chapter 11.96A RCW, sits alongside this. TEDRA provides a flexible framework for resolving questions about wills, trusts, and estates — including binding nonjudicial agreements among the interested parties — without full-blown litigation. It is a genuinely useful statute for families that need to fix an ambiguity, modify a trust, or settle a dispute efficiently.
The upshot is that in Washington, avoiding probate is a weaker argument for a trust than it is in California. The stronger arguments are estate tax planning, privacy, real property in other states, incapacity management, and controlling how beneficiaries receive their shares.
Community Property, Community Property Agreements, and Basis
Washington is a community property state. Under Internal Revenue Code section 1014(b)(6), when one spouse dies, both halves of community property receive a new income tax basis at fair market value. For a couple who bought a Puget Sound home decades ago, that can eliminate an enormous amount of built-in capital gain, which matters all the more given Washington’s capital gains tax on certain sales.
Washington spouses may also enter a community property agreement under RCW 26.16.120. A comprehensive agreement typically characterizes all property as community and provides that at the first death, everything vests immediately in the survivor — no probate at all for the first estate. For many Washington couples this is attractively simple.
It is also, for a couple with a taxable estate, potentially a very expensive mistake. A community property agreement that vests everything in the survivor makes it impossible to fund a credit shelter trust, which is precisely how the first spouse’s Washington exclusion is lost. Couples who signed such an agreement decades ago, when the estate was small, frequently have no idea it is still in force and still overriding their newer trust documents. Any Washington couple whose combined estate approaches the exclusion should have their community property agreement reviewed, revoked, or replaced with a version that preserves the ability to fund a bypass trust or to disclaim.
Washington Transfer on Death Deeds
Washington has adopted the Uniform Real Property Transfer on Death Act as chapter 64.80 RCW. A Washington owner may record a transfer on death deed naming a beneficiary who takes the property automatically at death, while the owner retains complete ownership and the unrestricted right to sell, mortgage, or revoke during life.
The deed must be recorded before death to be effective, and it is revocable only by a recorded instrument — not by a will. It transfers the property subject to any mortgage and to certain claims, and it does nothing at all for incapacity. It also does not coordinate with estate tax planning: a TOD deed sends the property to the named beneficiary regardless of what a bypass trust needs. For a straightforward transfer of a single Washington home it is a useful, low-cost tool. For a taxable estate it should be used only as part of a deliberate plan.
The Washington Homestead Exemption
Washington substantially strengthened its homestead exemption in 2021. Under RCW 6.13.030, the exemption is the greater of $125,000 or the county median sale price of a single-family home in the preceding calendar year for the county where the property sits.
There is deliberately no single statewide dollar figure, and the amount changes annually and varies enormously between counties. In an expensive county the protected amount can be many times the floor. Because the applicable number depends on the county and the year, it should be confirmed against current data rather than assumed. Like all homestead exemptions, it protects against most unsecured creditors and does not defeat a mortgage, tax lien, or certain other obligations.
The Core Washington Estate Plan
Will With Nonintervention Powers
A Washington will should nominate a personal representative, request nonintervention powers, waive bond, and — for a couple with a taxable estate — either establish the credit shelter trust or create a disclaimer structure that allows the survivor to decide at the first death. Washington does not recognize holographic wills executed in the state; a valid Washington will requires two competent witnesses.
Revocable Living Trust
In Washington the trust is chosen primarily for estate tax architecture, privacy, out-of-state real property, incapacity management, and beneficiary protection rather than for probate avoidance alone. It is also the natural home for a credit shelter or QTIP structure.
Durable Power of Attorney
Washington has adopted the Uniform Power of Attorney Act. The document should expressly grant the powers the Act treats as requiring specific authority — gifting, creating or amending a trust, changing beneficiary designations, creating survivorship interests — because those are exactly the powers a family later needs for tax and long-term care planning. Without a durable power of attorney, the alternative is a guardianship proceeding under Washington’s guardianship and conservatorship act.
Health Care Directive and Durable Power of Attorney for Health Care
Washington uses a Health Care Directive — the living will — for treatment preferences, together with a durable power of attorney appointing a health care agent. A POLST form may be appropriate for someone with a serious advanced illness, and a mental health advance directive is available in Washington for those who want one. A HIPAA authorization should accompany the package.
Nonresidents Who Own Washington Property
Washington taxes real property and tangible personal property located in the state that is owned by a nonresident decedent, with the tax apportioned based on the ratio of Washington property to the total gross estate. An Idaho, Oregon, or California resident who owns a vacation home in Washington has Washington estate tax exposure and may leave their family an ancillary Washington probate. Holding the property in a trust or a properly structured entity can address the probate issue and should be evaluated before the property passes.
Marital Agreements and Your Washington Estate Plan
Because Washington is a community property state, how assets are characterised between spouses decides what an estate plan can actually direct. A will or trust can only dispose of what the testator owns, and in a marriage that question is often less obvious than it looks — particularly where a business was started before the wedding, where separate funds were used to pay down a jointly titled home, or where one spouse has children from an earlier marriage. A prenuptial or postnuptial agreement settles the characterisation in advance instead of leaving it to be argued later. See Washington prenuptial and postnuptial agreements for how these are drafted and what makes them enforceable here.
Frequently Asked Questions About Washington Estate Planning
What is the Washington estate tax exclusion right now?
It depends on the date of death. For deaths between January 1 and June 30, 2026, the exclusion is $3,076,000 with rates up to 35%. For deaths from July 1 through December 31, 2026, it is $3,000,000 with rates reverting to a 10% to 20% range. Inflation indexing begins with 2027.
Can my surviving spouse use my unused Washington exclusion?
No. Washington has no portability. Preserving both exclusions requires a credit shelter or disclaimer trust and assets titled so the trust can actually be funded.
We signed a community property agreement years ago. Is that a problem?
It can be. An agreement that vests all property in the survivor at the first death prevents a credit shelter trust from being funded and can forfeit an entire exclusion. Couples approaching the exclusion should have the agreement reviewed against their current documents.
Do I need a living trust to avoid probate in Washington?
Usually not for that reason alone. Nonintervention probate under chapter 11.68 RCW is efficient and there is no percentage fee. Trusts in Washington earn their keep through estate tax planning, privacy, out-of-state property, and beneficiary protection.
Does a Washington estate tax return have to be filed if no tax is owed?
Often yes. Under RCW 83.100.050(1) the filing requirement is triggered by the gross estate reaching the exclusion amount, before deductions. An estate that owes nothing may still have a return to file.
