Hidden Estate Tax Traps for Seattle Homeowners

Estate tax is not only a problem for the very wealthy. In Washington, many regular homeowners are surprised to learn that their house, retirement accounts, and other assets can add up to a taxable estate. This can happen even if they feel firmly middle class and have never thought of themselves as “rich.”

Seattle and King County home values have grown a lot over time. That is great when you are building equity, but it can create estate tax issues down the road. At Salmon Bay Law Group, we see this come up when people come to us for estate planning and we help them add up all of their assets and see the full picture. Our goal here is to explain some of the common estate tax challenges in plain language and share some practical, high-level ideas for planning ahead.

Why Washington’s Estate Tax Catches so Many Off Guard

Washington has its own estate tax that is separate from the federal estate tax. The 2026 federal unified gift and estate tax exemption is $15,000,000 per person. This generally means that estates greater than $15 million may be subject to estate taxation at the federal level. At the state level, the Washington estate tax exclusion amount is currently $3,076,000 per person –set to decrease to $3 million for deaths occurring on or after July 1, 2026.

This means that Washington residents who are nowhere near the federal limit can still face substantial exposure to the Washington estate tax, depending on the value of their total assets. Beginning July 1, 2026, Washington estate tax rates will range from 10% to 20% of taxable value. (In 2025, the Washington legislature increased the top rate to 35%, and then quickly repealed that increase effective July 1, 2026.)

When the state looks at your estate, it usually considers the total value of what you own at death, such as:

• Your primary residence  
• Vacation homes or cabins  
• Rental or investment property  
• Retirement accounts like IRAs and 401(k)s  
• Bank and investment accounts  
• Annuities, life insurance policies, and other financial instruments
• Valuable collections – such as jewelry, art, or vintage automobiles 

Many Seattle homeowners do not feel “wealthy.” They may have a modest income and be careful with spending. Despite this, appreciation on a Seattle home purchased many years ago can lead to a dramatic increase in value. Add in a retirement account, some savings, maybe a vacation cabin, and a Washington resident can cross the state’s estate tax threshold without realizing it.

The surprise usually comes when someone sits down to calculate the total value of everything they own. What felt like “just our home and savings” turns into an amount large enough that the state may require an estate tax return when they pass away, and may assess a tax on amounts over the applicable exclusion amount.

How Your Seattle Home Can Push You Over the Line

For many people in Seattle and surrounding areas, the family home is the single largest asset. Seattle’s steady real estate growth means that a house bought decades ago for a relatively low price might now be worth several times that amount.

Here is how that can increase estate tax risk:

• The entire fair market value of the home counts, not what you originally paid
• Appreciation is “on paper” until you sell, but it still matters for estate tax 
• A second property like a Whidbey Island cabin, a rental condo, or inherited land stacks on top of your main home’s value

A few common misconceptions can make things worse:

• “My mortgage balance protects me.”  

The estate usually looks at the net value, meaning home value minus debt. A mortgage does reduce the net value of the home, but as the loan gets paid down, your equity grows. Over time, that can raise your estate tax exposure, even if your lifestyle does not change.

• “I will sell before I die.”  

Many people plan to sell their homes without materializing a plan to do so. Health changes, family needs, or market shifts can get in the way. Without a plan, your estate may still be based on the home’s value at your death. Additionally, selling the property to a beneficiary during your lifetime can create capital gains tax exposure. In some cases, letting the beneficiary inherit the home after your death can significantly reduce capital gains tax due when the property is eventually sold.

• “It is only a problem if all my money is in real estate.”  

Washington state looks at everything you own at the time of your death. This includes home equity, investments, retirement accounts, life insurance proceeds, valuable collections, and other Washington property, all of which come together to create the total estate value.

Marriage, Inheritances, and Estate Tax Surprises

Being married in a community property state like Washington creates its own set of questions. Many couples assume that being married means estate tax will not be a concern, or that everything simply passes without any issues. That is not always true.

Here are a few ways surprises show up for couples and families:

• Community property rules can affect who owns what portion of an asset, which can matter for planning.  
• The way the home is titled can matter. Real property purchased before marriage and held in only one spouse’s name may not pass entirely to the surviving spouse if the owner does not have a valid Will or proper Trust in place. 
• If the first spouse dies and everything just passes to the survivor with no estate planning, the surviving spouse may be more likely to have a taxable estate when they later pass away.  
• Consulting with a probate attorney when the first spouse dies and properly administering their estate can sometimes help reduce or even eliminate estate tax exposure at the second death – but it is important to have proper estate planning documents, including Wills or Trusts, prepared while both spouses are living.  

Inheritances can add another layer of complexity, and may push a homeowner into estate tax exposure territory. For example:

• A Seattle homeowner might inherit a parent’s home in Spokane.  
• A surviving spouse may inherit a large retirement account or life insurance benefit.  

On their own, each asset may not seem like a big deal. But when the value of each asset is added on top of a Seattle home that has grown in value, the combined estate value can result in exposure to Washington estate tax. Adult children are often the ones who discover this when they are trying to settle a parent’s estate while also processing their grief.

Simple Moves That Can Help Reduce Estate Tax Risk

The good news is that many families can take steps to reduce or manage estate tax exposure with early, thoughtful planning. The best practice is to talk with an estate planning attorney about your potential estate tax liability.

An experienced estate planning attorney may talk with you about ideas like:

• Credit shelter trust for the surviving spouse

A credit shelter trust is a type of “testamentary trust,” meaning that that the trust language is included in a Will. The credit shelter trust can be set up when you die for the benefit of your surviving spouse. Credit shelter trusts can be “mandatory,” meaning that your assets must be placed in the trust, or “disclaimer,” meaning that your spouse can choose whether to fund the trust. 

• Assets held in the credit shelter trust can be used by your spouse, and any unused assets (and their income and appreciation) will not be included in your spouse’s estate at his or her death. You can control how the trust’s assets will be distributed—whether to your children, grandchildren, other family members or friends, or charities—when your spouse dies.

The credit shelter trust works in Washington by using, or “sheltering,” your Washington estate tax exclusion amount when you die. Using the exclusion, your spouse may currently be able to shelter up to $3 million of your assets from taxation upon your spouse’s own death. Without a Will or Trust that provides for the creation of a credit shelter trust – and is lawfully signed and properly witnessed in advance of your death – this “use it or lose it” tax benefit will go to waste. A properly drafted and funded credit shelter trust can save your spouse’s estate up to several hundred thousand dollars in estate taxes, letting more funds go to your children or other beneficiaries. 

• Lifetime gifting  

Carefully planned gifts to children, grandchildren, or other loved ones during your lifetime can move assets out of your future estate. This works in Washington because the state has no gift tax. Selecting which assets to give should be done with the advice of an attorney, financial planner, and/or tax advisor, and you should always keep ample resources for your comfort level and lifetime needs.

• Beneficiary designations  

Retirement accounts and life insurance policies often pass according to beneficiary designations that you place on the accounts or policies, not according to your Will or Trust. Making sure your beneficiary designations are coordinated with your overall estate plan can help avoid unwanted tax results and also ensure that your distribution wishes are carried out at your death.

• Charitable giving  

Leaving part of your estate to charitable causes you care about can support those organizations while also lowering the size of your taxable estate. Some people choose to give during their lifetime, through their Will or Trust, by beneficiary designations, or a combination. 

In Washington, estate tax funds are deposited into the Education Legacy Trust Fund. This Fund provides funding for students across the state, ranging from pre-kindergarten learning programs to students in higher education programs, such as community colleges and work-study programs.  

No matter what tools are used, one thing is consistent: your plan should be reviewed from time to time. Washington laws can change. Family dynamics change – whether through marriage, divorce, birth of a child, loss of a spouse, or otherwise. Your net worth can change over time. A plan that made sense 10 years ago may not address your current needs and concerns.

Take Control of Your Estate Tax Picture Now

Waiting until there is a health scare or financial crisis often makes planning harder and more stressful. A calm, proactive look at your estate tax liability can help you make choices on your schedule instead of reacting during a crisis.

For Seattle and King County homeowners, a good starting point is simply to get clear on what you own. That can include getting updated information about:

• Your home’s current market value  
• Your mortgage balance and any home equity lines of credit  
• Other real estate, including out-of-state property  
• Balances in retirement accounts, bank accounts, and investments  
• Life insurance and beneficiary information
