Understanding Washington State’s Estate Tax
When people think about estate taxes, they often think of extremely wealthy families with very large estates.
In Washington, however, estate tax planning can become relevant much sooner than many families expect.
Washington imposes its own estate tax, separate from the federal estate tax. For individuals who pass away on or after July 1, 2026, Washington’s applicable exclusion amount is $3 million.
For homeowners throughout Bellevue, Kirkland, and the greater Seattle area, where real estate values can represent a significant portion of a family’s wealth, understanding Washington’s estate tax should be an important part of the estate planning conversation. For families concerned about Washington estate taxes, a Seattle, WA estate planning lawyer can help assess their estate and develop a plan that addresses potential tax obligations.
What Is the Washington Estate Tax?
Washington’s estate tax is a tax imposed on the transfer of certain property at death.
It is important to distinguish an estate tax from an inheritance tax.
Washington does not currently impose an inheritance tax on the person receiving an inheritance. Instead, the estate tax is imposed on the deceased person’s estate when applicable.
In other words, the tax is generally addressed as part of administering the estate before the remaining property is distributed to beneficiaries.
What Is Washington’s Estate Tax Exclusion?
For individuals who die on or after July 1, 2026, Washington’s estate tax exclusion amount is $3 million.
This means Washington estate tax planning may become relevant for families whose estates approach or exceed that amount.
It is important to understand that the filing threshold is based on the gross estate, not simply the amount remaining after debts and other deductions.
An estate may therefore have a Washington estate tax filing requirement even if deductions ultimately result in little or no estate tax being owed.
What Counts Toward the Value of Your Estate?
Your estate may be larger than you think.
When people estimate their net worth, they often focus on their home, bank accounts, and investment portfolio. Estate tax calculations can include a much broader range of property.
Depending on your circumstances, your gross estate may include assets such as:
- Your home and other real estate;
- Bank accounts;
- Investment accounts;
- Retirement accounts;
- Business interests;
- Life insurance;
- Vehicles;
- Certain jointly owned assets;
- Annuities;
- Assets held in Trust; and
- Other property you own or have certain interests in at death.
For many Washington families, appreciating real estate, retirement savings, investments, and life insurance can cause the value of an estate to grow much more quickly than expected.
Does a Revocable Living Trust Avoid Washington Estate Tax?
No.
A Revocable Living Trust can be an extremely useful estate planning tool, but simply placing assets into a Revocable Living Trust does not remove those assets from your taxable estate.
A Revocable Living Trust may help with goals such as:
- Avoiding probate for properly funded assets;
- Planning for incapacity;
- Maintaining greater privacy;
- Managing assets for beneficiaries; and
- Creating an organized structure for estate administration.
Estate tax planning, however, requires separate consideration.
This is an important distinction because “avoiding probate” and “avoiding estate tax” are two different estate planning goals.
How Much Is the Washington Estate Tax?
Washington uses a graduated estate tax.
For deaths occurring on or after July 1, 2026, rates range from 10% to 20% of the Washington taxable estate, depending on the amount subject to tax.
The tax is not simply calculated by multiplying the entire value of the estate by the highest applicable rate.
Instead, allowable deductions and the applicable exclusion are taken into account before the Washington taxable estate is determined, and the graduated tax table is then applied.
Because the calculation can become complicated, families approaching the Washington estate tax threshold should consider planning before a taxable event occurs.
What Deductions May Be Available?
The value of the gross estate does not necessarily equal the amount on which Washington estate tax will ultimately be paid.
Depending on the circumstances, allowable deductions may include certain:
- Debts;
- Funeral expenses;
- Estate administration expenses;
- Transfers to a surviving spouse;
- Charitable gifts;
- Qualified family-owned business interests; and
- Qualifying farm property.
Which deductions apply depends on the particular estate and applicable law.
What About Married Couples?
Married couples should pay particular attention to Washington estate tax planning.
It is easy to assume that if a couple’s combined estate is below twice the individual exclusion amount, there is nothing to worry about.
Estate tax planning for married couples is more nuanced.
How assets are owned, what happens when the first spouse dies, and how the couple’s estate planning documents are structured can all affect the eventual tax result.
Depending on the family’s circumstances, estate planning strategies may include Trust planning designed to preserve available estate tax benefits and provide flexibility for the surviving spouse.
This is one reason married couples with substantial assets should evaluate estate taxes as part of their estate plan rather than assuming everything can simply pass outright to the surviving spouse.
Washington Has Special Rules for Certain Personal Residences
Washington also provides a special personal-residence exclusion for purposes of determining whether certain estates of married individuals or registered domestic partners are required to file an estate tax return.
This rule can affect the filing-threshold calculation in qualifying circumstances.
Importantly, the personal-residence exclusion is a filing-related rule and does not necessarily mean the home’s value disappears from the estate tax calculation if a return is otherwise required.
Because the requirements are specific, homeowners should not assume that their primary residence is automatically excluded from Washington estate tax.
What About Family-Owned Businesses?
Washington provides a qualified family-owned business interest deduction for estates that satisfy specific requirements.
For qualifying estates, this deduction can significantly affect the estate tax calculation.
However, the requirements are detailed, and owning a family business does not automatically mean the estate qualifies.
Business owners should consider estate planning well before retirement or death, particularly when the business represents a substantial portion of the family’s wealth.
Why Washington Homeowners Should Pay Attention
Washington’s estate tax can be particularly relevant for longtime homeowners.
Consider someone who purchased a home decades ago for a relatively modest amount. Today, that same property may be worth significantly more.
Add retirement accounts, investment accounts, life insurance, savings, and other assets, and an estate can approach Washington’s threshold even when the individual does not consider themselves particularly wealthy.
This is especially relevant throughout Bellevue, Kirkland, and surrounding Eastside communities, where real estate can represent a substantial portion of an individual’s estate.
Estate Tax Planning Should Happen Before It Is Needed
One of the most important things to understand about estate tax planning is that many strategies are significantly more effective when implemented during your lifetime.
Depending on your assets, family, and goals, planning may involve:
- Reviewing how assets are owned;
- Coordinating beneficiary designations;
- Creating or updating Trusts;
- Evaluating lifetime gifting strategies;
- Planning for married couples;
- Reviewing life insurance;
- Evaluating business succession planning; and
- Coordinating your estate plan with your financial and tax advisors.
There is no single estate tax strategy that works for every family.
The appropriate approach depends on what you own, whom you want to protect, and what you ultimately want your wealth to accomplish.
Do Not Wait Until Your Estate Reaches the Threshold
You do not need to have a $3 million estate today for Washington estate tax planning to matter.
If your estate is approaching the threshold, consider where it may be five, ten, or twenty years from now.
Your home may appreciate. Your investments and retirement accounts may grow. You may receive an inheritance, purchase additional property, or build a successful business.
Estate planning should account for where your financial life is heading—not simply where it stands today.
