Most people assume that being married automatically provides certain estate planning protections—but that’s not always the case when one spouse is not a U.S. citizen. Citizenship can affect taxes, gifting, joint property, and the way assets pass at death.
Understanding these rules now can prevent costly surprises later and help you create a plan that truly protects your spouse and your family.
At Rincker Law, we help couples—mixed‑citizenship or otherwise—structure their estate plans so assets transfer smoothly and tax‑efficiently.
Noncitizen Spouses Are Treated Differently for Estate and Gift Taxes
U.S. citizen spouses receive an unlimited marital deduction, meaning they can transfer unlimited amounts to each other during life or at death without incurring estate or gift tax.
But this rule does not apply when the surviving spouse is not a U.S. citizen.
This can create unexpected tax exposure—unless proper planning is done.

How a Qualified Domestic Trust (QDOT) Helps
To receive the same tax benefits usually available to married couples, a U.S. citizen spouse can create a Qualified Domestic Trust (QDOT).
A QDOT allows:
- Assets to pass to a noncitizen spouse without immediate estate tax, and
- Required estate taxes to be paid after the noncitizen spouse passes away.
Key QDOT Requirements
- The noncitizen spouse must generally be the sole beneficiary during their lifetime.
- A U.S. trustee is required.
- The spouse receives income from the trust, but principal distributions may trigger tax.
A QDOT can be essential for couples who want to minimize taxes and ensure long‑term financial protection.
Jointly Owned Property May Be Fully Taxable
For married U.S. citizens, the law generally assumes each spouse owns 50% of jointly titled property. Only half is included in the deceased spouse’s estate.
This assumption changes when one spouse is a noncitizen.
Example
If a home worth $200,000 is jointly owned and the U.S. citizen spouse dies first, the entire $200,000 may be included in the deceased spouse’s taxable estate unless the noncitizen spouse proves they contributed to the purchase.
This rule can significantly increase estate tax exposure without proper documentation or planning.
Gift Rules Are Different Too
U.S. citizen spouses can usually make unlimited gifts to each other without gift tax.
However, when gifting to a noncitizen spouse, the unlimited marital deduction does not apply.
Gift Limits for 2026
A citizen spouse can transfer up to $194,000 per year to a noncitizen spouse without gift tax.
If the gift exceeds that amount, the citizen spouse must either:
If the gift exceeds that amount, the citizen spouse must either:
- Use part of their lifetime exemption, or
- Pay gift tax.
Understanding these thresholds helps families avoid unintended tax consequences.
Don’t Forget State Estate and Inheritance Taxes
Even if no federal estate tax is owed, some states impose their own estate or inheritance taxes with much lower exemptions.
This can affect:
- Mixed‑citizenship couples
- Couples with property in multiple states
- Families assuming they are below federal tax thresholds
An estate plan must account for both state and federal rules.
We Can Help You Plan With Confidence
