Do Beneficiaries Pay Taxes on Inheritance in Washington? IRA, 401(k), and Other Assets

Most people who inherit assets in Washington spend the first few weeks after a death convinced that a tax bill is coming for them personally. The assumption is understandable — Washington's estate tax makes headlines, and the word "inheritance" suggests the beneficiary is on the hook. In most cases, they are not. But the exceptions matter enormously, particularly for anyone inheriting a traditional IRA or 401(k).

Here is what beneficiaries actually owe, and where the confusion comes from.

Washington Has No Inheritance Tax

Washington State levies an estate tax — a tax on the right of the estate to transfer assets to beneficiaries. The estate pays this tax before distribution. The beneficiary receives what is left after the estate's taxes and debts are settled.

Washington does not have an inheritance tax. An inheritance tax is levied on the recipient of the assets based on who they are and how much they receive. States like Pennsylvania, Maryland, and Kentucky use this model. Washington has never adopted it.

This means that if you inherit cash, stocks, a family home, or personal property from a Washington estate, you receive those assets without owing any Washington state tax on the receipt. You do not file a tax return because you received an inheritance.

The Step-Up in Basis: Why Inherited Property Is Usually Tax-Free to Sell

The federal tax code provides a powerful tool called the step-up in basis under Internal Revenue Code Section 1014. When someone dies, the cost basis of their capital assets — real estate, stock portfolios, business interests — is adjusted to fair market value on the date of death.

If the decedent bought stock for $80,000 that was worth $300,000 at death, the beneficiary inherits it with a $300,000 basis. If the beneficiary sells it immediately for $300,000, there is zero capital gain and zero federal capital gains tax.

In Washington specifically, this benefit extends even further for married couples. As a community property state, Washington applies the step-up to both the decedent's half and the surviving spouse's half of any community property. A couple who bought a home for $150,000 that is worth $900,000 at the first spouse's death sees the entire property's basis adjusted to $900,000 — not just the decedent's half. The surviving spouse can sell immediately with no capital gains obligation on the $750,000 of appreciation.

This is one of the most powerful and least understood tax advantages available to Washington residents, and properly documenting the date-of-death fair market value is essential to capturing it.

Where Beneficiaries Do Owe Tax: IRAs and 401(k)s

Here is where the rules change significantly. Traditional IRAs and traditional 401(k)s are funded with pre-tax dollars — the original contributions were deducted from income and never taxed. When someone dies and leaves one of these accounts to a beneficiary, the beneficiary inherits the deferred tax obligation along with the money.

Every dollar a beneficiary withdraws from an inherited traditional IRA or inherited 401(k) is treated as ordinary income in the year it is withdrawn. This is not an inheritance tax — it is regular federal income tax on wages and income that was simply deferred. The beneficiary is completing what the original account owner started: paying income tax when the money comes out.

For a beneficiary who inherits a $200,000 traditional IRA, withdrawing the entire amount in one year could push them into a significantly higher tax bracket, resulting in a federal tax bill of $40,000 to $60,000 or more depending on their other income. A more strategic approach is to spread withdrawals across multiple years.

The SECURE Act and its successor rules require most non-spouse beneficiaries to fully distribute inherited IRAs within 10 years of the original owner's death. Within that 10-year window, beneficiaries have flexibility in timing withdrawals to minimize tax impact. In years when other income is lower — perhaps after retirement or a period of reduced employment — larger withdrawals may be less costly.

Surviving spouses have additional options. A surviving spouse who inherits an IRA can roll it into their own IRA, effectively treating it as their own account. This defers required minimum distributions until the surviving spouse's own required beginning date.

Inherited Roth IRAs

Roth IRAs are different. Contributions were made with after-tax dollars, and qualified distributions are tax-free. If you inherit a Roth IRA, withdrawals are generally tax-free as long as the original account was held for at least five years. Non-spouse beneficiaries still face the 10-year distribution rule, but the distributions themselves typically carry no income tax obligation.

Washington's Capital Gains Excise Tax: Rarely Triggered by Inherited Assets

Washington enacted a 7% excise tax on long-term capital gains exceeding an inflation-adjusted deduction ($278,000 for 2025). This tax applies to gains from selling stocks, bonds, and business interests.

However, real estate is explicitly exempt from Washington's capital gains tax. And because of the step-up in basis at death, inherited investment assets typically have minimal recognizable gain when sold promptly after the decedent's death. The stepped-up basis resets the gain to near zero, which also resets the Washington capital gains exposure to near zero.

Washington's capital gains tax is also explicitly inapplicable to assets held in retirement accounts, including IRAs and 401(k)s — those are governed entirely by federal income tax rules, not the Washington capital gains excise.

What Beneficiaries Should Actually Track

If you are a beneficiary in Washington, here is what to pay attention to:

What you owe nothing on:

• Cash from a bank account or brokerage account distributed from the estate
• Real estate transferred to you through probate or a personal representative's deed
• Life insurance proceeds (these are income-tax-free by federal law)
• Stocks and bonds distributed from the estate (basis is stepped up to date of death value)

What you may owe ordinary income tax on when you take withdrawals:

• Inherited traditional IRA
• Inherited traditional 401(k) or 403(b)
• Inherited SEP-IRA or SIMPLE IRA

What determines the estate's tax bill before you receive anything:

• Washington estate tax (paid by the estate if gross estate exceeds $3,000,000)
• Federal estate tax (paid by the estate if gross estate exceeds $15,000,000 — rare)

The practical implication for beneficiaries is this: the main thing to plan around is the inherited retirement account. If the decedent left you an IRA, work out a 10-year withdrawal strategy before taking the first distribution. The goal is to take larger distributions in years when your taxable income is lowest, paying tax in lower brackets rather than pulling everything out at once.

What Happens If the Estate Can't Pay the Estate Tax Before Distributing to You

One scenario that creates genuine liability for beneficiaries is early distribution. If an executor distributes assets to beneficiaries before the estate has satisfied its Washington estate tax obligation, the DOR can recover from the beneficiaries who received those assets — up to the amount they received. This is not the beneficiary's fault per se, but it means you have a financial interest in ensuring the executor has resolved the estate's tax liabilities before issuing your distribution.

Ask the executor whether the estate tax return has been filed and whether the DOR has issued a tax release. That release is the document that signals the state is satisfied and distribution can safely proceed.
