Seattle Inheritance Tax Rules When a Parent Dies

Washington Has No Inheritance Tax — But the Estate Tax Is Very Real

Inheriting money in Seattle has gotten complicated with all the misinformation flying around. When I helped my mother sort through my grandmother’s affairs in Bellevue three years ago, the estate attorney opened with: “Washington doesn’t have an inheritance tax.” My mom exhaled. Then he added: “But the estate itself might owe state tax.” That distinction — confusing but genuinely critical — stops most Seattle residents cold. Today, I will share everything I learned navigating that process, including the mistakes I made personally.

Here’s the actual rule. Washington imposes zero tax on what you receive as a beneficiary. You inherit $500,000, you owe $0 to Washington state on that money personally. But if your parent’s total estate exceeds $2.193 million — the Washington state estate tax exemption for 2025 — the estate itself must file a return and pay state tax before a single dollar passes to you. The federal exemption sits much higher at $13.61 million for 2025, so most Seattle-area estates never touch that threshold. Most. Not all.

The practical takeaway: if your parent’s total assets — home, brokerage accounts, retirement accounts, life insurance, everything — stayed under roughly $2.2 million, you’re almost certainly not dealing with Washington estate tax. Exceeded that number? The executor will need professional help filing Form WA-706 before distributing anything to beneficiaries. Don’t skip that step.

What Actually Happens to Taxes on Assets You Inherit

This is where most people get blindsided. Inheriting assets doesn’t trigger income tax on the inheritance itself — but what happens next depends entirely on what type of asset landed in your hands.

The Stepped-Up Basis Advantage

But what is stepped-up basis? In essence, it’s a reset of an asset’s cost value to whatever it was worth on the date your loved one died. But it’s much more than that — it’s potentially one of the largest tax breaks available to ordinary people, and most heirs never fully appreciate it.

My neighbor inherited 2,000 shares of Microsoft from her father last year. He’d bought them back in 1998 at roughly $27 per share — around $54,000 total. When he died, Microsoft was trading around $378. She inherited those shares at the $378 date-of-death value, not the original $27. Sold them the following week at $385. She owed capital gains tax only on that $7 difference. Not the $351 per-share gain her father accumulated over 25 years. That’s the magic of stepped-up basis, and it’s entirely legal.

Real estate works identically. Parent bought their Seattle home in 1985 for $180,000. Worth $1.2 million at death. You inherit it at the $1.2 million basis. Sell immediately for $1.2 million — you owe $0 in capital gains tax. That’s a massive advantage available only to inherited assets, not gifts. Important distinction. The catch: this only applies to assets held in the deceased’s individual name or certain trust structures. Retirement accounts are a completely different story.

Inherited IRAs — A Completely Different Animal

Inherited traditional IRAs do not get stepped-up basis. Period. Your parent left you an IRA worth $400,000 — you inherit it at $400,000, but every dollar you withdraw gets taxed as ordinary income. And the SECURE Act blew up the old rules in 2020. If you inherited the IRA after December 31, 2019, you generally have 10 years to empty it completely. Miss that window and the IRS charges a 25% penalty on whatever remains.

Probably should have warned myself about this one, honestly. When I inherited my uncle’s Roth IRA worth $89,000, I assumed it was tax-free because Roth accounts are tax-free. True — for him. For me, I’m apparently subject to the same 10-year emptying rule, though at least Roth withdrawals themselves aren’t taxable to me. Traditional IRA beneficiaries face a real crunch. Forced distributions from an inherited IRA stack directly on top of your ordinary income that year, potentially shoving you into a higher bracket. A 45-year-old who inherits a $600,000 traditional IRA and pulls $60,000 in year one just added $60,000 to their taxable income. Don’t make my mistake — plan the distribution schedule before touching anything.

Inherited Real Estate in Seattle Has Its Own Wrinkles

Washington charges no capital gains tax on real estate sales — unlike some states — but stepped-up basis still matters enormously when you eventually sell. One thing most heirs miss: your principal residence exemption does not transfer to an inherited property. Live somewhere else and later sell the inherited Seattle home for a gain? That gain is taxable. That’s a future problem, though. For now, secure the property and resist the urge to sell while you’re still grieving.

The First 90 Days After Inheriting Money in Seattle

The executor or administrator handles probate or trust administration, but your own actions during the first 90 days set your tax posture for the next five years. So, without further ado, let’s dive in — in order.

Step One: Engage Estate Counsel Early (Week One)

While you won’t need a team of lawyers, you will need a handful of qualified professionals — starting with an estate attorney. If the estate is sizable or complex, the executor should hire one immediately, not after three months of fumbling around. In Seattle, expect to pay $3,000 to $8,000 for estate administration counsel depending on complexity. This person walks the executor through asset collection, creditor notification, and filing requirements. If nobody has hired an attorney yet and you’re a major beneficiary, you have standing to push for one. Use it.

Step Two: Document Date-of-Death Values for Every Asset (Weeks One to Four)

Get statements from every financial institution for the exact date your parent died. Bank accounts, brokerage accounts, retirement accounts, life insurance proceeds — all of it. For real estate, you’ll need a professional appraisal unless the property was recently and accurately assessed. These numbers become the stepped-up basis for non-retirement assets. Missing or guessing at these values later creates tax headaches that take months to untangle. The IRS requires them for any estate return, and you’ll need them to calculate capital gains when you eventually sell inherited investments.

Step Three: Do Not Immediately Liquidate Anything (Weeks One to Twelve)

Frustrated by the pace of estate administration, many heirs start pressuring the executor to just sell everything and split the proceeds. Resist that impulse. Cashing out inherited brokerage accounts to cover estate bills, selling the house to divide proceeds among siblings — decisions made in haste lock in tax consequences you cannot undo. Give the executor and attorney time to map out the full picture. Most estate administrations run six to twelve months anyway. That timeline exists for good reasons.

Step Four: Understand What You Actually Inherited (Weeks Two to Six)

Taxable brokerage account, 401(k), traditional IRA, Roth IRA, real estate, or some combination? Each carries different rules and timelines. An inherited 401(k) has different distribution requirements than an inherited traditional IRA. An inherited house has different tax treatment than inherited stock. The executor should provide a clear asset breakdown within the first month — at least if they’re doing their job properly. If that list doesn’t materialize, ask for it directly.

Step Five: Get Accounts Retitled (Weeks Two to Eight)

Banks, brokers, and retirement account custodians all need official notification of the death and then must retitle accounts — either into the estate’s name or directly into your name if you’re the sole designated beneficiary on that account. The executor handles this. But if the executor is slow, you can call institutions yourself to expedite the process. Some custodians, like Fidelity or Schwab, have dedicated inheritance departments that move faster when beneficiaries call directly.

Financial Advisor vs. CPA — Which Do You Actually Need

Probably should have opened with this section, honestly. These two professionals serve completely different functions, and if the inheritance is substantial, you genuinely need both.

A CPA Handles the Estate Tax Return

If the Washington estate exceeded $2.193 million, a CPA with estate tax experience must file Form WA-706 with the state and Form 706 with the IRS. Not optional. Not a DIY project. The deadline is nine months after death — no extensions on the payment itself. In Seattle, estate tax CPAs charge $2,500 to $6,000 for a straightforward return. The executor pays this from estate assets, not from your pocket as a beneficiary.

Even if the estate owes no estate tax, the executor may need a CPA to file a final Form 1040 for the deceased and possibly a Form 1041 estate income tax return if the estate generates income during administration. Most Seattle CPAs working with estates charge $250 to $400 per hour. That’s the going rate — shop around but don’t discount experience to save $50 an hour.

A Financial Advisor Helps You Plan What to Do With What You Received

A fee-only financial advisor might be the best option for inheritance planning, as this situation requires someone whose compensation isn’t tied to selling you products. That is because inherited assets — particularly IRAs with 10-year distribution windows — need a drawdown strategy that accounts for your existing income, not just the inherited money in isolation. Should you keep inherited stock or diversify? Hold the inherited house as a rental or sell? How do you spread inherited IRA distributions across 10 years without blowing up your tax bracket each year?

I’m apparently wired toward overthinking this stuff, and a fee-only advisor works for me while commission-based advisors never quite gave me unbiased answers. In Seattle, expect to pay $2,000 to $5,000 for a comprehensive inheritance integration plan. Interview at least three advisors. Ask specifically about inherited IRA distribution strategies and stepped-up basis planning — if they can’t answer those questions fluently, keep looking.

Common Mistakes Seattle Heirs Make With Inherited Assets

I’ve watched friends repeat these errors. Each one cost real money.

Cashing Out an Inherited IRA in Year One

A beneficiary inherits a $275,000 traditional IRA and decides to “clean it up” by withdrawing everything immediately. That $275,000 gets stacked on top of their ordinary income, potentially shoving them from the 24% bracket into the 32% bracket. Federal tax alone: roughly $66,000. Spread across 10 years, the tax hit shrinks dramatically. The SECURE Act window gives you flexibility — use every year of it.

Selling the Inherited Home Without Documenting Stepped-Up Basis

An heir sells the inherited Seattle home three months after the parent’s death without commissioning an appraisal at date of death. They estimate the value — maybe they guess low. Later, the IRS questions whether stepped-up basis was properly established. Months of correspondence, potential penalties. Get the appraisal done in week one or two. A residential appraisal in Seattle typically runs $500 to $800. That’s cheap insurance.

Ignoring the 10-Year IRA Distribution Deadline

You inherit an IRA in 2024. You have time, you think. Years pass. In 2034, you realize the entire balance was supposed to be withdrawn by then. The IRS assesses a 25% penalty on whatever remains. A $180,000 leftover balance generates $45,000 in penalties. Set a calendar reminder right now. Seriously — do it before you finish reading this.

Not Updating Your Own Estate Plan After a Windfall

You inherit $400,000 and your existing will still reflects the version of your finances from five years ago. If you die without updating your documents, your estate could face unnecessary tax exposure or your assets could land with unintended beneficiaries. Update everything within six months of receiving a large inheritance. That was true before the SECURE Act, and it’s even more true now.

Making Major Financial Decisions While Grieving

Overwhelmed by the inherited house, you list it immediately. Rattled by inherited investment accounts you don’t recognize, you liquidate everything for “safety.” Decisions made in the first three months of grief get regretted at a strikingly high rate. Wait. Get professional guidance. Then act. The assets will still be there in 90 days, and you’ll be in a better position to think clearly about them.

If you’ve just inherited from a parent in the Seattle area, your first call goes to an estate attorney if administration is still underway, and your second call goes to a fee-only financial advisor who specifically handles inherited assets. Those two conversations cost less — often significantly less — than the mistakes they prevent. That’s what makes getting this right so worthwhile for Seattle families navigating an already difficult time.
