Why cross-border transfers create special risks
Transferring wealth across jurisdictions triggers a combination of legal, tax, and practical issues that seldom exist for purely domestic estates. The most common risk areas are:
- Tax overlap: different jurisdictions can assert estate, inheritance, gift, and income tax claims on the same asset or transfer. Treaties sometimes mitigate double taxation, but they rarely eliminate all compliance burdens (see IRS and treaty guidance).
- Probate fragmentation: assets located in different countries or U.S. states may require separate probate or succession procedures, increasing time and legal fees.
- Conflicting law: differences in forced heirship, marital property regimes, or trust recognition can frustrate testator intent.
- Reporting and disclosure: U.S. persons must meet foreign-account reporting (FinCEN Form 114, commonly called FBAR) and certain asset reporting under IRS Form 8938 (FATCA). Non-U.S. beneficiaries may have their own reporting rules.
These issues affect expatriates, cross-border families, owners of foreign real estate, dual citizens, green-card holders, and anyone holding investments or trusts abroad.
Practical steps to evaluate exposure
- Map your assets and relationships
- List assets by country and legal title (individual name, joint, trust, company).
- Identify citizenship, residency, and domicile for you and key beneficiaries.
- Note beneficiary locations and whether heirs are minors or foreign nationals.
- Determine situs and controlling law
- For real estate, the situs is the property’s location and local succession rules usually apply.
- For personal property (bank accounts, securities), situs can depend on account location and the account’s governing law.
- For companies and trusts, examine the governing documents: the trust deed, corporate charter, and the law specified for interpretation.
- Run a tax and procedural checklist for each jurisdiction
- Estate/inheritance taxes: whether the jurisdiction levies a death tax, who is subject, and which assets are taxed.
- Gift taxes and lifetime exemptions: some countries tax lifetime transfers differently than death transfers.
- Reporting requirements: FBAR, FATCA (Form 8938), local disclosure rules for foreign inheritances.
- Treaties and credits: availability of estate or inheritance tax treaties and foreign tax credits.
Common planning tools and how they behave across borders
-
Wills: A will should be valid where signed and under the law it chooses, but local law can override a foreign will for in-country assets. Use local wills for assets in multiple countries to prevent probate complications.
-
Trusts: Trusts can be powerful when a jurisdiction recognizes them. However, several countries do not treat foreign trusts favorably for tax or asset-protection purposes. Pay attention to whether a trust is a grantor trust for U.S. tax purposes and how local law taxes trust distributions.
-
Life insurance: Often outside probate and potentially tax-efficient, but proceeds can be taxable to beneficiaries in some countries. Using life insurance to provide liquidity for estate taxes is a common strategy.
-
Corporate ownership and holding companies: Holding real estate or securities through foreign or domestic entities can change tax treatment and probate exposure, but it adds complexity and must be structured with both tax and corporate law in mind.
-
Beneficiary designations and joint ownership: Simple and effective to transfer assets quickly, but exposed to local rules like forced heirship or community property claims.
Cross-border tax topics to watch (U.S.-focused highlights)
-
Federal estate, gift, and GST taxes: The U.S. applies estate and gift taxes to U.S. situs assets and to U.S. citizens and domiciled residents on worldwide assets. The basic exclusion amount and related rules change over time—refer to the IRS for current figures: https://www.irs.gov/estate-gift-tax.
-
Nonresident aliens (NRAs) and U.S. situs assets: NRAs are generally subject to U.S. estate tax only on U.S.-situated assets. Planning to change situs (e.g., through ownership structures) is delicate and requires professional input.
-
Reporting: U.S. persons holding foreign financial accounts must file FinCEN Form 114 (FBAR). High-value foreign financial assets may also require Form 8938 under FATCA. See FinCEN and IRS guidance (FinCEN: https://www.fincen.gov, IRS: https://www.irs.gov).
-
Treaty relief: Estate tax treaties vary. Some limit double taxation on certain assets or provide credits; review treaty language and consult tax counsel.
Practical examples (anonymized client cases from my practice)
-
Case A: A U.S. citizen living in Spain held a portfolio in Spanish brokerage accounts and U.S. brokerage accounts. Failure to align beneficiary designations and to create a Spanish-compliant will exposed the estate to dual probate and heavy fees. The solution combined a local will for Spanish assets, re-titling certain accounts into a U.S. revocable trust where appropriate, and coordinated beneficiary designations.
-
Case B: A dual citizen inherited German real estate. Germany’s succession rules and potential inheritance tax applied; we used a holding company structure and a life insurance policy to provide heirs with liquidity for anticipated tax bills while pursuing treaty relief.
These examples show the value of early, coordinated planning across legal systems.
Checklist: Questions your advisor should answer
- Which jurisdiction’s laws control each asset and disposition?
- Does any jurisdiction apply forced heirship or limit testamentary freedom?
- Which assets will require local probate or succession proceedings?
- What are the current estate, inheritance, and gift tax rules and thresholds in each jurisdiction (and any applicable treaties)?
- What reporting forms will be required when you die or transfer assets during life?
- How will trusts or foreign entities be taxed where they were created and where they operate?
Common mistakes and how to avoid them
-
Mistake: Relying on a single-country will. Fix: Create local wills for assets in different countries, coordinated to avoid conflicts.
-
Mistake: Ignoring beneficiary designations. Fix: Review and update beneficiary forms, and align them with your estate plan.
-
Mistake: Assuming treaty protection applies. Fix: Confirm treaty language and applicability with counsel—treaties are asset- and resident-specific.
-
Mistake: Neglecting reporting obligations (FBAR/FATCA). Fix: Maintain records and file required disclosures annually.
Practical strategies that often work
-
Start early and coordinate: Build an integrated plan that combines wills, trusts, insurance, and entity structures across relevant countries.
-
Use local counsel: Engage attorneys and tax advisors in each jurisdiction plus a cross-border estate specialist to coordinate the plan.
-
Liquidity planning: Ensure funds (insurance, bank accounts, or life insurance) are available to pay taxes and local fees so heirs aren’t forced to sell assets.
-
Consider residency and domicile planning carefully before changing tax status; effects can be long-lasting.
-
Regular reviews: Laws and treaty positions change—review cross-border plans at least every 2–3 years or after major life events.

Professional insight and closing guidance
In my practice managing cross-border client estates, the single biggest value-add is early coordination: mapping assets, engaging local counsel, and creating liquidity for taxes. Even modest estates can trigger surprising local taxes or probate costs when assets sit in multiple countries. An effective cross-border plan favors clarity (who gets what and under which law), liquidity (to pay taxes and fees), and compliance (to avoid fines and penalties).
This article is educational and not legal or tax advice. Cross-border wealth transfer rules are highly fact-dependent and subject to change. Consult qualified estate, tax, and immigration professionals in each relevant jurisdiction before implementing any plan.
