Understanding Qualified Domestic Trusts (QDOTs)

When it comes to estate planning, every family is unique. And for families where one spouse isn’t a U.S. citizen, a specific tool called a Qualified Domestic Trust—commonly known as a QDOT—can offer critical protection and peace of mind.

Let’s explore what a QDOT is, how it works, and whether it might make sense for your family.

What Is a Qualified Domestic Trust (QDOT)?

A Qualified Domestic Trust is a type of trust that helps U.S. citizens pass on their assets to a non-citizen spouse in a tax-efficient way.

Normally, married couples can leave unlimited assets to each other without paying estate taxes, thanks to what's called the unlimited marital deduction. But this benefit doesn’t apply when the surviving spouse isn’t a U.S. citizen. That’s where a QDOT comes in.

Think of a QDOT as a financial bridge—it allows a non-citizen spouse to receive income from inherited assets while postponing the estate taxes that would otherwise be due right away.

Why QDOTs Matter

Congress created QDOTs to solve a real problem: ensuring that families with mixed citizenships aren’t unfairly penalized by estate tax laws.

Key Benefits of a QDOT:

• Defers estate taxes until the non-citizen spouse either takes principal from the trust or passes away

• Provides income to support the surviving spouse

• Protects assets from being depleted or mismanaged

• Gives families time for tax planning and future decisions

Who Should Consider a QDOT?

A QDOT could be an important estate planning strategy if:

• You’re a U.S. citizen married to someone who is not a U.S. citizen

• Your estate is expected to exceed the federal estate tax exemption ($13.99 million in 2025)

• You want your spouse to be financially secure after you're gone

Even if you’re under the current exemption amount, it’s worth considering:

• The exemption is scheduled to drop after 2025

• Your estate could grow over time

• Your spouse may not become a U.S. citizen

Real-Life Example

Maria and Pablo’s story:
Maria is a U.S. citizen. Her husband, Pablo, is a Mexican citizen. They live in California, and Maria’s estate is worth $15 million. Without a QDOT, Pablo would face a large estate tax bill if Maria passed away. With a QDOT in place, Pablo can receive income from those assets without facing immediate estate taxes—offering stability while preserving their family’s wealth.

How Does a QDOT Work?

A QDOT has specific rules and structure to qualify for its tax benefits:

Trustee Requirements

• At least one trustee must be a U.S. citizen or a U.S. bank

• If the trust holds over $2 million:

  • A U.S. bank must serve as trustee, or

  • The individual U.S. trustee must provide a bond or letter of credit worth 65% of the trust’s value

Administrative Requirements

• The trust must be governed by U.S. law

• All records must be kept in the U.S.

• The executor must elect QDOT treatment on the estate tax return

• The U.S. trustee must have the authority to withhold estate taxes from distributions

How the Money Flows

Here’s what typically happens:

1. The U.S. citizen spouse passes away

2. Their assets are transferred to the QDOT

3. The non-citizen spouse receives income from the trust (tax-free)

4. If principal is withdrawn, estate taxes may apply—unless it’s for a hardship

5. When the non-citizen spouse dies, any remaining assets go to the next beneficiaries

Tax Implications to Know

• Income (like interest or dividends) can be paid out without triggering estate tax.

• Principal distributions usually do trigger estate taxes unless it's a hardship (think: medical expenses, education, or basic support).

• The estate tax is calculated based on the rates in effect when the U.S. citizen spouse died—not at the time of withdrawal.

Important note: If your spouse becomes a U.S. citizen after your death, and meets residency requirements, the trust may no longer need to follow QDOT rules—and estate taxes might not apply at all.

When a QDOT Makes Sense

Here are some examples of how families might use a QDOT:

The Retirement Plan

John and Mei plan to retire in the U.S. Mei isn’t a U.S. citizen and doesn’t plan to become one. A QDOT ensures Mei receives income from John’s assets without triggering immediate estate taxes.

The Family Business

Carlos places his $20M family business in a QDOT. His wife Elena can receive income from the business, and their children can eventually inherit it—without needing to sell the company just to cover taxes.

The Recent Immigrant

David’s wife Sofia is new to the U.S. and still pursuing citizenship. David creates a QDOT just in case he passes away before she becomes a citizen, ensuring her financial security.

Alternatives to a QDOT

QDOTs are powerful, but they’re not the only strategy to consider. Other options might include:

• Annual tax-free gifts to a non-citizen spouse ($190,000 in 2025)

• Life insurance to cover future estate taxes

• Transferring assets into your spouse’s name during your lifetime

• Planning for citizenship, which could eliminate the need for a QDOT altogether

What To Do Next

If you’re married to a non-citizen spouse and think a QDOT might apply to your situation:

1. Talk with an estate planning attorney experienced in international and cross-border planning

2. Take inventory of your assets and compare them to the federal exemption amount

3. Review your estate plan regularly, especially as tax laws change

4. Decide if a QDOT or other strategy best fits your family’s long-term goals

QDOT FAQs

Can my spouse access the principal?
Yes, but this usually triggers estate taxes unless it’s a hardship distribution.

What if my spouse becomes a U.S. citizen later?
If they meet residency requirements and no taxable distributions occurred before citizenship, the QDOT restrictions may be lifted.

Can I put a retirement account in a QDOT?
Yes. Retirement accounts can be transferred into a QDOT Rollover IRA.

Can a QDOT be created after I pass away?
Yes, your executor or surviving spouse can establish one before the estate tax return is filed.

Who can serve as trustee?
At least one trustee must be a U.S. citizen or bank. Your non-citizen spouse can be a co-trustee, but not the only trustee.

The Bottom Line

A Qualified Domestic Trust is a powerful tool for protecting your non-citizen spouse from unnecessary financial hardship while preserving your family’s legacy. It offers tax deferral, asset protection, and the flexibility to adapt to life’s changes—like eventual citizenship.

Estate planning is never one-size-fits-all. If your family includes international ties, it’s worth exploring whether a QDOT fits into your broader plan.
