How to Avoid Washington State Estate Tax

Washington taxes estates worth more than $3 million, and the rate climbs to 20% on the largest estates. You reduce or avoid that bill the same way Washington families have for years: give assets away while you are alive (Washington has no gift tax), split a married couple’s exemption with a credit shelter trust because Washington does not allow portability, move life insurance out of your taxable estate, and hold real estate through partnerships or LLCs. For the property side, a 1031 exchange defers the capital gains tax so your heirs inherit at a stepped-up basis.

Universal Pacific 1031 Exchange has spent 30+ years helping real estate investors defer capital gains taxes through our Qualified Intermediary service, which frees up capital for the next purchase. Book a free consultation and we’ll walk through how a 1031 exchange fits your estate.

Below we break down what Washington’s estate tax actually costs in 2026, who pays it, and the specific moves that keep more of your estate with your family instead of the state.

What Is the Estate Tax in Washington State?

Washington charges an estate tax on what a person owns when they die, before anything passes to heirs. People call it the “death tax.” It applies only to estates that clear a set dollar threshold, and it is paid out of the estate, not by the individual beneficiaries. Washington does not have an inheritance tax, and neither does the federal government, so heirs are not taxed personally on what they receive.

The tax is figured on the fair market value of everything the decedent owned at death, then paid before the estate is distributed under the will. The governing statute is RCW 83.100.

The 2026 Threshold and Rates (Updated for ESB 6347)

Washington’s estate tax changed twice in twelve months, so the date of death matters. For anyone who dies on or after July 1, 2026, these are the current numbers:

• Exclusion amount: $3,000,000. Estates below this owe nothing. This figure is now frozen. The 2025 inflation index in the statute references a discontinued price series, so the exclusion no longer rises each year.
• Rates: 10% to 20%, graduated by the size of the taxable estate.
• Filing: a Washington estate tax return is due nine months after the date of death if the gross estate exceeds the threshold.

Here is the full Washington estate tax rate schedule (Table W) for deaths on or after July 1, 2026, applied to the Washington taxable estate, meaning the amount above the exclusion:

Why the “changed twice” matters: Senate Bill 5813, effective July 1, 2025, raised the exclusion from the old $2.193 million up to $3 million and pushed the top rate to 35% for estates over $9 million, briefly the highest in the country. Ten months later, Engrossed Senate Bill 6347 (signed March 24, 2026) rolled the top rate back to 20% for deaths on or after July 1, 2026. So the 35% top rate applied only to a narrow window: deaths between July 1, 2025 and June 30, 2026. If you are planning today, the 10%–20% schedule above is the one that governs.

How Washington Compares to the Federal Estate Tax

The federal exemption is far higher. Under the One Big Beautiful Bill Act, the 2026 federal estate tax exemption is $15 million per person ($30 million for a married couple), and it is now permanent rather than scheduled to sunset. Anything above that is taxed at 40% federally.

The gap is the whole problem for Washington residents. A $6 million estate owes no federal estate tax, but it does owe Washington roughly $550,000 (18% on the $3 million above the state exclusion). The strategies below target that state gap.

Who Is Affected by the Washington Estate Tax?

It reaches both residents and non-residents whose estate exceeds the $3 million exclusion. For a resident, the state totals real estate, investment accounts, bank balances, retirement assets, and life insurance proceeds. Non-residents are taxed only on tangible property located in Washington, such as real estate. Intangibles like stocks and bonds are generally exempt for non-residents unless their home state fails to extend the same courtesy to Washington residents.

How to Avoid Washington State Estate Tax

None of these are loopholes. They are the planning tools estate attorneys use every day, and each one shrinks what the state can tax.

1. Lifetime Gifting

Washington has no gift tax. That single fact makes gifting the most direct lever you have: money you give away during life is out of your Washington taxable estate, full stop, with no state gift tax to worry about.

The limit is federal, not state. You can give up to $19,000 per recipient in 2026 to as many people as you like with no filing at all. Go over that, and you file IRS Form 709 and the excess counts against your $15 million federal lifetime exemption. For most families, that federal ceiling is never a factor, which means gifting quietly pulls assets out of the state’s reach year after year.

Say a Washington resident gifts a child $500,000 in one year. The first $19,000 is free; the remaining $481,000 is reported on Form 709 and trimmed from the federal lifetime exemption, leaving $14,519,000. No Washington tax is due either way.

2. Credit Shelter Trusts (Bypass Trusts)

This is the move that answers a question people search directly: does a trust avoid Washington state estate tax? A credit shelter trust does, for married couples, and it exists specifically because Washington does not allow portability.

Portability, at the federal level, lets a surviving spouse absorb the deceased spouse’s unused exemption. Washington offers no such thing. If the first spouse leaves everything outright to the survivor under the unlimited marital deduction, the survivor’s estate is later taxed on the whole amount, and the first spouse’s $3 million exclusion is simply gone.

A credit shelter trust saves it. Instead of passing everything to the survivor, up to $3 million is routed into a trust at the first death. The survivor still benefits from that trust during their lifetime, but its value is not counted in their taxable estate. The result is that a couple can shelter roughly $6 million from Washington estate tax instead of $3 million.

An example: a spouse dies with a $5 million estate. Left outright to the survivor, it passes tax-free under the marital deduction, but at the second death the full $5 million is taxable and only one $3 million exclusion applies. Route $3 million into a bypass trust instead, and only the remaining $2 million is exposed at the second death.

3. The Marital Deduction and Surviving Spouses

A related search we hear often: does a surviving spouse pay Washington state estate tax? Usually not at the first death. The unlimited marital deduction lets one spouse leave any amount to the other, tax-free, as long as the surviving spouse is a U.S. citizen.

The catch is timing. The marital deduction postpones the tax; it does not erase it. When the second spouse dies, the combined estate is taxed against a single $3 million exclusion, and without portability the first spouse’s exclusion is wasted. That is exactly why the credit shelter trust above is worth setting up before the first death rather than after.

4. Irrevocable Life Insurance Trusts (ILITs)

Life insurance payouts are counted in your Washington gross estate, which surprises a lot of people. An irrevocable life insurance trust owns the policy instead of you, so the death benefit lands outside your taxable estate and reaches your beneficiaries without adding to the tax.

The trust either buys a new policy or takes over an existing one. It has to be set up correctly, and a policy you transfer in has a three-year lookback, so this is one to do with a tax professional. Note that an irrevocable trust is not the same as a revocable living trust; a revocable trust does nothing to lower estate tax because you still control the assets.

5. Family Limited Partnerships (FLPs) and LLCs

A family limited partnership or LLC lets you move ownership of assets to your heirs in shares while you keep control. Parents typically hold the general-partner interest and run the assets; children hold limited-partner interests that carry ownership but no control. Only the share you still hold counts in your Washington taxable estate, and minority, non-controlling interests are often valued at a discount, which lowers the taxable number further. These structures also shield family assets in a divorce or lawsuit. Have an estate attorney set them up; the IRS scrutinizes ones that are done sloppily.

6. The Qualified Family-Owned Business and Farm Deduction

If a working family business or farm makes up most of an estate, Washington offers a qualified family-owned business interest (QFOBI) deduction on top of the standard exclusion. For 2026 dates of death, the maximum QFOBI deduction is $3,076,000, per the Washington Department of Revenue. Stacked on the $3 million exclusion, that can shield a substantial family enterprise from the death tax. There are ownership and participation tests to meet, so confirm eligibility with a Washington estate attorney before relying on it.

How to Defer Washington Estate Tax on Real Estate With a 1031 Exchange

Be clear on what a 1031 exchange does and does not do. It will not lower your estate tax. What it does is defer the capital gains tax on investment real estate, which matters a great deal in Washington where you may be holding property that has appreciated for decades.

A 1031 exchange lets you sell an investment property and roll the proceeds into a replacement property without paying capital gains tax at the sale. You can repeat it as many times as you want. When you die still holding the property, your heirs inherit it at a stepped-up basis, which wipes out the deferred capital gains entirely. The estate may still owe Washington estate tax on the property’s value, but the capital gains liability is gone.

One caveat: a 1031 exchange does not defer Washington’s Real Estate Excise Tax (REET). Because the rules on timing and titling are strict, most investors work with a Qualified Intermediary who can handle the 1031 exchange and keep the transaction compliant.

Who Qualifies for a 1031 Exchange in Washington State?

Anyone holding real estate for investment or business use can qualify, provided they follow the IRS rules. The properties must be like-kind, and the exchange timelines are firm: 45 days to identify a replacement and 180 days to close. Title must stay with the same taxpayer under the same-taxpayer rule, and you report the exchange to the IRS on Form 8824. You will still owe Washington REET on the sale, and you cannot complete an exchange without a Qualified Intermediary, so choose one with Washington market experience.

When to Consider a 1031 Exchange in Washington

Reach for a 1031 exchange when you are selling an investment property and want to defer the capital gains tax rather than hand it to the IRS. It fits when you are reinvesting sale proceeds into another property, consolidating several holdings, repositioning into a different market, or setting up a portfolio to pass to heirs at a stepped-up basis.

Put a Plan in Place Before You Need It

Avoiding Washington’s estate tax is not one move, it is a stack of them: gift while you are alive, split the exemption with a credit shelter trust, keep life insurance in an ILIT, hold property through an FLP, and claim the family-business deduction if it applies. Together they can take a seven-figure estate below the line or well past it.

For the real estate in your estate, that is where we come in. At Universal Pacific 1031 Exchange, our Qualified Intermediaries defer the capital gains tax on your Washington property so more of it compounds for the next generation. Visit our office or start an exchange with a free consultation.

FAQs

Does a trust avoid Washington state estate tax?

A credit shelter (bypass) trust does, for married couples. Because Washington has no portability, routing up to $3 million into a bypass trust at the first spouse’s death preserves that spouse’s exclusion, letting a couple shelter about $6 million total instead of $3 million. A revocable living trust does not reduce estate tax.

Does a surviving spouse pay Washington state estate tax?

Generally not at the first death, thanks to the unlimited marital deduction. The tax can hit the combined estate at the second death, though, because Washington gives the survivor only one $3 million exclusion and no portability. A credit shelter trust is the standard fix.

What is the Washington estate tax exemption for 2026?

$3,000,000 for deaths on or after July 1, 2026. It is frozen at that level because the statute’s inflation index no longer functions. (For deaths between January 1 and June 30, 2026, the inflation-adjusted figure was $3,076,000.)

Can a 1031 exchange help avoid estate tax in Washington?

No. A 1031 exchange defers capital gains tax on investment real estate; it does not reduce estate tax. It is still valuable in estate planning because heirs inherit exchanged property at a stepped-up basis, which erases the deferred capital gains.

What assets are included in the Washington estate tax?

Cash, bank and investment accounts, trust assets, tangible personal property such as art and jewelry, real estate, life insurance proceeds, and retirement benefits.

Is there a limit to how many 1031 exchanges I can do?

No. There is no cap on the number of 1031 exchanges or the number of properties you exchange, as long as each one follows the IRS rules and uses a Qualified Intermediary.
