Bellevue and the wider Seattle Eastside are home to a large immigrant workforce — engineers, researchers, physicians, and entrepreneurs who married spouses from outside the United States. When one spouse is a U.S. citizen and the other is not, a routine estate plan can fail in a costly way: the unlimited marital deduction, which normally lets a citizen pass any amount to a surviving spouse tax-free, does not apply when the surviving spouse is not a U.S. citizen. The workaround Congress created is the Qualified Domestic Trust (QDOT), codified at Internal Revenue Code §2056(d).
What a QDOT Is and Why It Exists
A QDOT is a trust that receives assets from a deceased U.S. citizen (or resident) for the benefit of a surviving non-citizen spouse. Once assets are placed in the QDOT, federal estate tax is deferred rather than immediately due — preserving the policy behind the marital deduction while protecting the Treasury's ability to collect tax if the non-citizen spouse leaves the U.S. The deferral continues for the life of the surviving spouse, and tax is owed only when principal is distributed from the trust or when the surviving spouse dies.
Without a QDOT, the non-citizen spouse receives only a $60,000 exemption (IRC §2056(d)(2)) — a fraction of the $13.61 million federal exemption available to citizen spouses in 2026. Any amount above $60,000 passing outright to a non-citizen spouse is taxed at the 40% federal estate tax rate on the decedent's death.
When a QDOT Is Required in Washington
A QDOT is needed when both of the following are true:
- The decedent was a U.S. citizen or U.S. domiciliary;
- The surviving spouse is not a U.S. citizen, and assets passing to that spouse exceed $60,000.
It does not matter whether the non-citizen spouse is a lawful permanent resident (green-card holder), an H-1B holder, or any other status — citizenship, not residency, controls the QDOT rule. A green-card holder who has not naturalized still needs a QDOT if the threshold is exceeded.
For Bellevue families, this scenario is common. A Microsoft or Amazon engineer who naturalized and married a spouse still on an H-4 visa, or a Chinese- or Indian-born couple where only one spouse has obtained citizenship, will frequently have a combined estate — home equity, RSUs, 401(k), life insurance — well above $60,000.
How a QDOT Interacts With Washington Community Property
Washington is one of nine community property states. Each spouse owns an equal, undivided one-half interest in property acquired during the marriage (RCW 26.16.030). At death, only the decedent's half of community property is included in their taxable estate; the surviving spouse's half is not taxed. This means the QDOT only needs to receive the decedent's half — but it must receive it properly.
Coordinating community property characterization with the QDOT election requires care. Separate property (assets owned before marriage or received by gift/inheritance) is 100% in the decedent's estate and is the first source of QDOT funding. Community property requires tracing and characterization, often through a community property agreement under RCW 26.16.120. A Bellevue estate planning attorney experienced with both cross-border and community property rules should draft the plan.
QDOT Requirements Under Federal Law
To qualify as a QDOT, the trust must satisfy several statutory requirements (IRC §2056(d); Treas. Reg. §20.2056A-2):
- U.S. trustee: At least one trustee must be a U.S. citizen or a domestic corporation (typically a U.S. bank or trust company).
- Irrevocable election: The executor must make the QDOT election on the federal estate tax return (Form 706), and the trust must be established before the return is filed.
- Withholding on distributions: The trustee must withhold and pay estate tax on any principal distribution to the surviving spouse before the spouse's death.
- Security bond or letter of credit: If the trust holds more than $2 million in assets, the trustee must either be a U.S. bank or the trust must post a bond or letter of credit equal to the deferred tax.
- Annual income tax filings: The trust files Form 5471 and annual QDOT information returns; trust income is taxable to the surviving spouse each year.
- No direct distributions to non-citizen beneficiaries: Distributions of principal (other than hardship) are taxable events; income distributions are not.
Washington Estate Tax: A Separate Problem
The QDOT only addresses federal estate tax. Washington State imposes its own estate tax (RCW 83.100) on estates above $2.193 million in 2026, at rates of 10% to 20%. Washington allows a marital deduction for property passing to a surviving spouse, but the statute does not require a QDOT for non-citizen spouses — meaning the state deduction is generally broader than the federal rule. Still, the interaction between the federal QDOT election and Washington's estate tax return (Form 501) must be coordinated, and the same QDOT trust can often satisfy both regimes when properly drafted.
For a Bellevue couple with a $1.5M home, $1M in retirement accounts, and $1M in RSUs and life insurance, the combined $3.5M estate comfortably exceeds Washington's threshold. Without planning, the decedent's half alone can trigger six figures of Washington estate tax.
Planning Strategies Around the QDOT
A QDOT is not the only tool for mixed-citizenship couples. Common strategies include:
- Naturalization first: If the non-citizen spouse is eligible to naturalize, doing so before the citizen spouse's death eliminates the QDOT requirement entirely.
- Lifetime gifting: The citizen spouse can gift up to $185,000/year (2026 annual exclusion for gifts to non-citizen spouses, IRC §2503(b)(2)) to shift assets out of the estate without using the QDOT.
- Life insurance trust (ILIT): A properly structured irrevocable life insurance trust removes policy proceeds from the taxable estate, avoiding the need to fund a QDOT with the death benefit.
- Bypass trust + QDOT: Fund a credit-shelter trust up to the federal exemption amount, then place the balance in a QDOT for the spouse.
Choosing a Trustee in Washington
Many Bellevue families prefer a family member as trustee, but the QDOT rules require a U.S. citizen or domestic corporation. Local trust companies in Seattle and Bellevue routinely serve as QDOT co-trustees alongside a family trustee, providing the required U.S. presence without giving up family oversight. For estates above $2 million, an institutional trustee is effectively required unless a bond is posted — and bonds are expensive and hard to obtain for large tax exposures.
Frequently Asked Questions
01What is a Qualified Domestic Trust (QDOT)?
A QDOT is a special trust authorized under Internal Revenue Code §2056(d) that allows a U.S. citizen decedent to leave assets in trust for a non-citizen surviving spouse and still qualify for the unlimited marital deduction, deferring federal estate tax until the trust is distributed.
02When do I need a QDOT in Washington State?
You need a QDOT if you are a U.S. citizen married to a non-citizen spouse and the assets passing to that spouse exceed the $60,000 non-citizen spouse exemption. Without a QDOT, the excess is taxed at the 40% federal estate tax rate immediately at death.
03Does Washington State have its own estate tax that a QDOT affects?
Yes. Washington levies its own estate tax starting at $2.193 million (2026) at 10-20%. A QDOT defers federal estate tax, but Washington also allows a marital deduction for property passing to a surviving spouse. The state rules differ from the federal QDOT rules and require separate analysis — the same trust can often satisfy both.
04Who can serve as trustee of a QDOT?
At least one trustee must be a U.S. citizen or a domestic corporation. Banks and trust companies in Washington, including those serving Bellevue and Seattle clients, commonly serve as institutional QDOT trustees. If the trust holds more than $2 million in assets, the trustee must be a U.S. bank or the trust must post a bond.
05Can a QDOT hold Washington community property?
Yes. Washington is a community property state, so one-half of community assets is included in the decedent's estate. The decedent's half can be placed in a QDOT for the non-citizen spouse, while the spouse's half is already theirs. Community property characterization and the QDOT election must be coordinated carefully.
