A qualified domestic trust under IRC § 2056A must meet six specific requirements beyond standard marital deduction rules. These requirements allow the U.S. government to collect estate tax on the deferred property when the surviving spouse receives distributions or dies. Failure to satisfy any requirement disqualifies the trust, making the entire marital share taxable at the first death.
Requirement 1: U.S. Citizen or Domestic Corporation Trustee
At least one trustee must be a U.S. citizen or domestic corporation. Treas. Reg. § 20.2056A-2(d)(2) requires an individual trustee to maintain a “tax home in the United States.”
A noncitizen surviving spouse can serve as co-trustee but not as sole trustee. The U.S. citizen or domestic corporation trustee must have the right to withhold tax on distributions (Requirement 2). Simply naming a citizen trustee without granting operational authority is insufficient.
For trusts exceeding $2 million, the requirement becomes stricter: at least one trustee must be an IRC § 581 U.S. bank or trust company, not merely any citizen or domestic corporation. A domestic law firm, citizen individual, or non-bank domestic corporation will not suffice.
Requirement 2: Withholding Authority on Distributions
The U.S. citizen or domestic corporation trustee must have the right to withhold the IRC § 2056A(b) tax from any corpus distribution. Treas. Reg. § 20.2056A-2(b)(1). This ensures the government collects the tax at distribution rather than relying on the noncitizen surviving spouse to file a return and pay voluntarily.
The trust document must expressly grant withholding authority. Silence is not sufficient; the trustee must have an affirmative right and obligation to withhold.
Requirement 3: Income to the Spouse
All income must be payable to the surviving spouse at least annually unless the trust qualifies as an estate trust (which exempts income distribution requirements). This requirement matches the standard marital deduction rules.
Income distributions from a QDOT are not subject to the IRC § 2056A(b) tax. Only principal distributions trigger the tax. This distinction makes characterizing distributions as income or principal critically important for QDOT administration.
Requirement 4: Election on the Estate Tax Return
The QDOT election must be made on the decedent’s timely filed Form 706. Treas. Reg. § 20.2056A-3(a). Unlike the QTIP election, partial QDOT elections are not permitted. However, a trust may be severed into multiple trusts, and the QDOT election can apply to one or more of the resulting trusts. Treas. Reg. § 20.2056A-3(b).
Once made, the election is irrevocable. If the estate tax return is filed without the QDOT election, the marital deduction is lost. The tax cannot be recovered by filing an amended return after the filing deadline.
Requirement 5: Regulatory Compliance for Collection
IRC § 2056A(a)(2) requires compliance with “any regulation which may be prescribed by the Secretary to ensure collection of any tax imposed by subsection (b).” This general authority allows the Treasury Department to issue detailed regulations in Treas. Reg. § 20.2056A-2.
Requirement 6: Security Based on Trust Size
The regulations impose two distinct security requirements depending on fair market value:
- Trusts exceeding $2 million. The trust must meet one of two alternatives. The first requires that at least one trustee be an IRC § 581 U.S. bank or trust company. The second allows any qualified U.S. trustee but requires a bond or letter of credit equal to 65% of fair market value. The bond or letter must come from a Treasury-approved surety company or financial institution. The 65% amount covers maximum estate tax (40% of corpus) plus interest and penalties. The bond must be adjusted annually based on current fair market value.
- Trusts at or below $2 million. The trust instrument must prohibit investing more than 35% of annually determined fair market value in foreign real estate. This restriction prevents assets from moving beyond U.S. tax collection reach while keeping compliance costs lower than bond requirements.
The $2 million threshold applies at the decedent’s death and is not inflation-adjusted. It includes the value of all QDOT trusts for the same surviving spouse.
Hardship Distribution Exception
The IRC § 2056A(b) tax on corpus distributions does not apply to distributions made for hardship. Treas. Reg. § 20.2056A-5(c) defines hardship as an “immediate and substantial financial need” related to the spouse’s health, maintenance, education, or support, or that of any person the spouse is legally obligated to support.
The hardship exception is narrow. It does not cover distributions for lifestyle enhancement or investment purposes. The trustee must document hardship circumstances for each distribution and maintain records to withstand IRS scrutiny.
Converting to a Standard Marital Trust
If the surviving spouse becomes a U.S. citizen after the QDOT is established, the trust can convert from QDOT status to a standard marital trust. The conversion eliminates the withholding requirement, security requirement, and IRC § 2056A(b) tax on future distributions. Specific regulatory conditions must be met, including that the surviving spouse was a U.S. resident at all times after the decedent’s death.
