Quick Read Summary (TLDR)

Estate planning in Florida is complex for married couples where one spouse is not a U.S. citizen because the unlimited marital deduction is unavailable, potentially leading to immediate federal estate tax liabilities on U.S. assets exceeding the small non-resident exemption. The Qualified Domestic Trust (QDOT) is a critical planning tool authorized by the IRS that defers this estate tax liability until the surviving non-citizen spouse passes away or receives principal distributions. To qualify, a QDOT must meet strict IRS requirements, including having at least one U.S. citizen or domestic corporation as a trustee, especially for high-value estates. Due to the intersection of federal tax law and international considerations, families with non-citizen spouses should consult an experienced Florida estate planning attorney to ensure proper QDOT implementation and compliance.

Florida has long been a popular destination for international families looking to invest in real estate and establish roots. However, when one spouse in a marriage is not a United States citizen, estate planning becomes significantly more complex. One of the most important tools available to address this challenge is the Qualified Domestic Trust, commonly known as a QDOT.

The Problem: Non-Citizen Spouses and the Marital Deduction

Under federal estate tax law, U.S. citizens who are married to other U.S. citizens enjoy the unlimited marital deduction. This provision allows a deceased spouse to transfer any amount of assets to the surviving spouse without triggering estate tax. However, this benefit does not extend to a surviving spouse who is not a U.S. citizen. The IRS has expressed concern that a non-citizen surviving spouse could leave the country with inherited assets, making it difficult for the government to collect estate taxes later.

The financial consequences can be severe. Non-resident aliens are entitled to an estate tax exemption of only $60,000 on U.S.-situated property, compared to approximately $15 million for U.S. citizens and permanent residents in 2026. Any amount above the $60,000 threshold can be taxed at rates as high as 40%. For a family that owns a Florida home or investment accounts, this means a potentially devastating tax bill due within nine months of the first spouse’s death.

How a QDOT Works

A Qualified Domestic Trust is authorized under Internal Revenue Code Section 2056A. Congress created it to balance two competing interests: the government’s need to collect estate taxes and the surviving spouse’s need for financial security. When assets are placed into a properly established QDOT, those assets qualify for the marital deduction even though the surviving spouse is not a U.S. citizen. The estate tax is deferred rather than eliminated.

Instead of transferring assets directly to the non-citizen surviving spouse at death, the assets are placed into the QDOT. The surviving spouse then receives income generated by the trust, such as interest, dividends, and rental income, on at least an annual basis. These income distributions are subject to regular income tax but not the special QDOT estate tax. However, if the trustee distributes any trust principal to the surviving spouse, that distribution triggers estate tax under Section 2056A. When the surviving spouse eventually passes away, the remaining trust assets are also subject to estate tax.

For example, imagine a U.S. citizen in South Florida who owns a $3 million estate and is married to a non-citizen spouse. Without a QDOT, the surviving spouse could face an immediate estate tax liability of over $1 million. With a properly structured QDOT, that tax is deferred, and the surviving spouse continues to benefit from the trust income for the rest of their life.

Key Requirements for Establishing a QDOT

The IRS imposes strict requirements for a trust to qualify as a QDOT. At least one trustee must be a U.S. citizen or a domestic corporation. If the trust assets exceed $2 million, at least one trustee must be a U.S. bank. Alternatively, an individual trustee must furnish a bond or letter of credit to the IRS equal to 65% of the fair market value of the trust assets. If the trust assets are valued at $2 million or less, no more than 35% of the trust property may consist of real estate located outside the United States.

The executor must also make an irrevocable QDOT election on the federal estate tax return (Form 706), due within nine months of death. The trust must be governed by U.S. state law and qualify as an ordinary trust under Treasury Regulation Section 301.7701-4(a).

The Hardship Exception and the Path to Citizenship

Not all principal distributions from a QDOT trigger estate tax. Under 26 C.F.R. Section 20.2056A-5(c)(1), distributions may be exempt if made because of an immediate and substantial financial need related to the health, maintenance, education, or support of the surviving spouse. However, this hardship exception is narrow and requires that no other reasonably available liquid assets exist to meet the need.

It is also worth noting that the QDOT rules no longer apply if the surviving non-citizen spouse becomes a naturalized U.S. citizen. If citizenship is obtained before the estate tax return is filed and the surviving spouse has been a U.S. resident at all times since the death, the unlimited marital deduction becomes available without a QDOT.

Florida’s Estate Tax Landscape

Florida does not impose a separate state estate tax or inheritance tax. Chapter 198 of the Florida Statutes addresses estate taxes but ties the state’s framework to the federal system. While this makes Florida attractive for international families, it does not eliminate the need for careful federal estate tax planning when a non-citizen spouse owns Florida property.

“If citizenship is obtained before the estate tax return is filed and the surviving spouse has been a U.S. resident at all times since the death, the unlimited marital deduction becomes available without a QDOT.”

The Importance of a Florida Estate Planning Attorney

Estate planning for families with non-citizen spouses involves a complex intersection of federal tax law, trust administration, and international considerations. As The Florida Bar has noted, estate planners in Florida are increasingly working with couples where one or both spouses are not U.S. citizens. Attempting to “go it alone” and navigate QDOT requirements without professional guidance could result in costly mistakes, including the loss of the marital deduction entirely. It is highly recommended that families in this situation consult an experienced Florida estate planning attorney who can determine whether a QDOT is the right strategy and ensure compliance with all IRS requirements.
