Estate planning across borders
By Richard C. Wilson, founder of the Family Office Club.
Key takeaway
Estate planning across borders starts with a family's citizenship and domicile history, an ownership map and the documents used in each country. Use these guides to organize questions about a noncitizen spouse, a nonresident owner, foreign inheritances and property held across borders.
Research notice: Reviewed against primary law. Minnesota will rules appear only as labeled examples, and other states differ. Ask an estate attorney or CPA to confirm asset classifications, elections, reporting obligations and the rules applicable to the relevant transfer before acting.
What the topic covers
The guides cover citizenship and domicile, U.S. estate tax questions for nonresident owners, qualified domestic trusts for noncitizen surviving spouses, estate tax treaties and foreign death tax credits. Separate guides address foreign wills, inheritance arrangements and assets received by a U.S. family from abroad.
Begin with an asset list that identifies the owner, ownership form, location and supporting records for each holding. Add both spouses' citizenship information, residence history, existing wills, trust instruments and prior transfer tax returns. Record missing information before the first planning meeting so advisers can identify what needs investigation.
Questions owners ask
Families ask how a noncitizen spouse changes gift planning, how jointly owned property is counted at death and what a QDOT requires. Property owners ask whether FIRPTA withholding starts with the sale proceeds or the gain. Executors ask which treaty, credit and filing questions need a separate review.
Start with the answers below, then follow the linked guide for implementation questions. For foreign law, bring the relevant documents to advisers in each jurisdiction. Ask them to review the same ownership records, wills and intended beneficiaries.
How the pieces connect
Organize the review in stages: establish the person's status, identify each asset and its ownership, then examine the particular transfer, deduction, treaty and reporting questions. Keep lifetime gifts, property held at death and later sales on separate lines of the worksheet. Match the supporting documents to each question.
For a married couple, place joint ownership records beside the spouse's citizenship history and any trust documents. For an inheritance, gather the estate's correspondence, transfer records, account statements and investment descriptions. For a property sale, add the purchase agreement and the buyer's intended use to the discussion packet.
Who meets this topic
Business owners, real estate investors and families with private investments can use these guides when a spouse is not a citizen, an owner lives abroad or assets span countries. Adult children and executors can start here when organizing an inheritance from someone who lived outside the United States.
Use the checklist before commissioning new documents or asking advisers to coordinate existing ones. Identify the question for each adviser, the records still needed and who will obtain them. Keep the original wills and a complete copy of every later document available for a coordinated review.

How does a QDOT work for a noncitizen surviving spouse?
A qualifying QDOT can remove the marital deduction bar for property passing to a noncitizen surviving spouse if the property otherwise qualifies for that deduction. Property can pass in the QDOT, be transferred to it before the estate return is made, or be irrevocably assigned to it under an assignment enforceable under local law made on or before that date.
The trust instrument generally must require an individual U.S. citizen trustee with a U.S. tax home or a domestic corporate trustee. No distribution other than income may be made unless such a trustee has the right to withhold the distribution tax. Collection safeguards and an executor election are also required.
The QDOT must be an ordinary trust maintained under state or District of Columbia law. Its administration must be governed by a particular such jurisdiction, with records or copies kept there. A trust instrument executed abroad can qualify if its governing law designation is effective under the designated jurisdiction's law.
A separate exception removes the citizenship bar if the spouse becomes a U.S. citizen before the day the estate return is made and resides continuously in the United States from the decedent's death until citizenship. Use the guide to review marital interests, security arrangements, election procedures and later tax events with counsel.

How do citizenship and domicile affect an estate?
For federal estate tax, a resident decedent is someone domiciled in the United States at death. Domicile requires living in a place with no definite present intention of leaving. Residence alone is insufficient, and changing domicile requires actual removal as well as intent.
The estate tax regulation defines the United States as the states and District of Columbia. Separate rules address citizenship connected with U.S. territories. Income tax residence is a separate statutory classification whose definition expressly excludes the estate and gift tax subtitle. Use the guide to organize citizenship records and the family's residence history for professional review.
-
How do estate tax treaties and foreign tax credits work?
An applicable death tax treaty can affect estate tax rules, but its actual provisions determine any relief. Identify whether the agreement contains estate tax or gift tax provisions before relying on it. An income tax treaty's existence alone establishes no particular estate tax benefit.
Use the guide for a separate review of foreign death tax credit eligibility, property situs, valuation caps, payment evidence and claim deadlines. Bring the possible treaty, foreign assessments, proof of payment, property values and estate returns. Ask the adviser to examine each asset and each tax payment before estimating relief.

How does U.S. estate tax apply to nonresident owners?
A nonresident noncitizen estate generally receives a $13,000 credit against federal estate tax, subject to statutory limits and treaty rules. The credit cannot exceed the tax imposed under IRC §2101. Previously allowed gift tax credit reduces the applicable credit amounts.
For possession cases governed by IRC §2209, the credit before that reduction is the greater of $13,000 or the proportion of $46,800 represented by the U.S. estate's share of the worldwide estate. Treaty obligations may require a proportionate credit based on the applicable federal credit for the year of death. Property exempt under a treaty is excluded from the U.S. property numerator. The statutory $13,000 and $46,800 amounts are not indexed.
Use the guide to examine asset classification and the separate estate return filing test, including its adjustments and any applicable treaty provisions. Bring issuer information, bank and debt records, insurance documents and prior gift tax returns. Request a separate analysis of partnership interests.

How should families review wills and inheritance across borders?
Review every will together with advisers in each relevant jurisdiction to address execution, possible revocation and foreign administration. Assemble all wills, later amendments, property ownership records and a list of the countries involved.
Use the guide to organize questions about recognition abroad, forced heirship and inheritance arrangements. Give each adviser the same documents and intended beneficiary list before commissioning changes.

What happens when a U.S. family inherits foreign assets?
Inherited property is generally excluded from gross income, but income from that property and inheritances of income are not covered by that exclusion. The exclusion also does not cover transfers by or for an employer to or for the benefit of an employee under IRC §102(c). Amounts included in a beneficiary's income under the trust and estate income tax rules receive the treatment specified in IRC §102(b).
A foreign source does not establish that later earnings, trust distributions or investment gains are free of tax. Use the guide to review information reporting separately, including Form 3520, foreign accounts and investment classification. Gather transfer values, account locations, estate correspondence and fund documents. Include inherited income rights and basis questions in the adviser review.
-
Can a will signed abroad revoke an existing will?
In Minnesota, for example, a validly executed later will signed abroad can revoke an existing will expressly or by inconsistency, and other states differ. Execution must comply with Minnesota §524.2-502, the execution place's law at execution, or the law of a place where the testator was domiciled, had an abode or was a national at execution or death.
Without express revocation, complete replacement depends on intent to replace the earlier will. A complete disposition of the estate creates a presumption of replacement. An incomplete disposition creates a presumption of supplementation. Either presumption can be rebutted by clear and convincing evidence. When supplementation applies, both wills operate to the extent they are consistent.
Foreign execution alone establishes neither preservation nor revocation. Minnesota's rules establish no recognition, administration or property transfer result abroad. Bring all documents to counsel for a coordinated review.

How are lifetime gifts to a noncitizen spouse treated?
Lifetime gifts to a noncitizen spouse generally receive no gift tax marital deduction, except for transfers resulting from acquiring rights under the joint and survivor annuity described in IRC §2523(f)(6). The current enhanced annual exclusion is $194,000 for aggregate gifts other than future interests that would qualify for the marital deduction if the spouse were a citizen.
The enhanced amount replaces the ordinary annual exclusion for those gifts. Future interest gifts to that spouse are reportable regardless of the total value of present interest gifts. The enhanced exclusion is indexed for inflation. Use the guide with a complete list of the year's gifts and the interests transferred.
-
How is joint property counted when a surviving spouse is not a U.S. citizen?
Joint property with a noncitizen surviving spouse generally follows the ownership and consideration rules, subject to statutory exceptions and applicable treaties. The qualified joint interest rule does not automatically apply.
The relevant rules cover survivorship joint tenancies, tenancy by the entirety and joint bank deposits payable to either owner or the survivor. The other owner's excluded contribution must be shown to have originally belonged to that owner and never to have come from the decedent for less than adequate and full consideration. When property or consideration came from the decedent for less than full consideration, exclusion is proportionate to the consideration furnished by the other owner.
For property jointly acquired by gift, bequest, devise or inheritance as a tenancy by the entirety, half the value is included. For survivorship joint tenants acquiring property that way whose interests are not otherwise specified or fixed by law, the included fraction is the property's value divided by the number of joint tenants.
The noncitizen spouse exceptions concern otherwise qualifying marital deduction property passing in a qualifying QDOT, transferred to one before the estate return is made, or enforceably and irrevocably assigned to one on or before that date. A separate exception applies if the spouse becomes a citizen before the day the return is made after continuous U.S. residence from death until citizenship. Bring contribution records and acquisition documents to counsel before estimating the included share.
-
Is FIRPTA withholding based on the sale price or the gain?
FIRPTA withholding generally uses the amount realized, rather than the gain, when a foreign person disposes of a U.S. real property interest as defined in IRC §897(c). The transferee generally must withhold 15%, subject to statutory exemptions and authorized relief.
The purchaser residence exception removes withholding when the transferee acquires the property for use as a residence and the amount realized does not exceed $300,000. A 10% rate applies when the transferee acquires the property for use as a residence, the amount realized does not exceed $1 million, and the exception in IRC §1445(b)(5) does not apply.
The $300,000 and $1 million thresholds are not indexed for inflation. Withholding is separate from final tax liability. Use the guide to review certifications, IRS qualifying statements and requests for reduced withholding or refunds.

Why can U.S. stock be treated differently at gift and death for a nonresident?
A nonresident noncitizen's lifetime gift of intangible property generally falls outside federal gift tax, while stock owned and held at death is U.S. property only if issued by a domestic corporation. The lifetime exception does not apply when IRC §877(b) applies to the donor in the transfer year. The estate tax classification remains subject to statutory exclusions and applicable treaties.
For gift tax imposed solely through that expatriation exception, the statute provides a credit for foreign gift tax actually paid on the gift. The intangible property exception does not extend to U.S. real or tangible property or resolve every expatriation case. Use the guide to compare a proposed gift with continued ownership at death.
