Can a NonCitizen Inherit a US Estate

Glenn just received the devastating news: his mother’s codicil, the one updating her estate plan after his sister’s divorce, was deemed invalid due to a missing witness signature. This means his mother’s original Will, drafted before his sister’s marriage, controls. Worse, the estate now faces a complex battle – Glenn’s mother owned a vacation home in California and a substantial brokerage account, but Glenn, a long-term resident of Canada, is the sole beneficiary. He’s staring down the barrel of a potentially costly probate process, and he’s understandably panicked about the tax implications.

As an estate planning attorney and CPA with over 35 years of experience in Escondido, California, I see scenarios like Glenn’s frequently. The good news is that a non-citizen can inherit a US estate. However, the process is often more intricate than for US citizens, and understanding the nuances of federal and California law is critical to minimizing tax burdens and avoiding probate pitfalls.

The first issue is domicile. The deceased’s domicile (their primary residence for legal purposes) determines which state’s probate laws apply. For Glenn’s mother, that’s California. This triggers California probate rules, which, while generally efficient, still require court oversight if the estate exceeds certain thresholds. Assets without valid beneficiaries may trigger probate if the total value of personal property exceeds $208,850 (for deaths occurring on or after April 1, 2025); a Will alone does not bypass this limit. A properly funded revocable living trust, however, would bypass probate entirely, regardless of Glenn’s citizenship.

What are the Tax Implications for a Non-Citizen Inheritor?

The US estate tax applies to estates exceeding a significant exemption amount—currently over $13 million. However, even if Glenn’s mother’s estate falls below this threshold, the income tax implications for Glenn as a non-resident alien are substantial. Dividends, interest, and capital gains generated by the inherited assets are typically subject to US income tax, often at a higher rate than for US citizens. This is where my CPA background becomes invaluable. A careful analysis of the asset’s cost basis is crucial. For example, inheriting stock with a low cost basis triggers immediate capital gains tax upon sale. Conversely, inheriting a property with a fair market value that’s drastically different from the original cost basis requires a professional appraisal to accurately determine the taxable gain. The potential for a step-up in basis upon death can drastically reduce these tax liabilities, but it requires meticulous documentation and proper estate planning.

How Does the Estate Administration Process Differ?

Glenn will need to obtain an Individual Taxpayer Identification Number (ITIN) from the IRS if he doesn’t already have one. The estate will also likely need to file Form 3520, Annual Return of Foreign Trust Income, even if Glenn isn’t directly receiving income from a trust—this is a common reporting requirement for estates involving non-resident beneficiaries. The executor of the estate will be responsible for withholding 30% of any income paid to Glenn, which can be applied against his eventual US tax liability.

What about Assets Held in LLCs or Businesses?

If Glenn’s mother owned interests in limited liability companies (LLCs), the situation becomes even more complex. The inheritance of these assets triggers potential ongoing reporting requirements. The executor needs to confirm the LLC’s operating agreement and ensure compliance with state and federal regulations. Notably, as of January 1, 2026, non-exempt LLCs must comply with FinCEN’s Beneficial Ownership Information (BOI) reporting; executors and beneficiaries managing inherited entities must file updated reports within 30 days of ownership changes to avoid significant civil penalties.

Are Digital Assets a Concern?

In today’s world, digital assets—cryptocurrency, online accounts, photos, and other electronically stored property—are often a significant part of an estate. Beneficiaries and executors are legally barred from accessing digital accounts, photos, and crypto-wallets unless the decedent explicitly granted authority in their Will, Trust, or via an ‘online tool’ under California’s RUFADAA (Probate Code § 870). Glenn needs to know if his mother had a digital asset inventory and a plan for accessing those accounts.

What if Glenn’s Inheritance Impacts Government Benefits?

It’s also crucial to assess whether Glenn’s inheritance will impact his residency status or any government benefits he might be receiving in Canada. While this is a Canadian matter, it’s essential to consider the potential implications. In California, effective January 1, 2026, California has reinstated asset limits ($130,000 for individuals) for non-MAGI Medi-Cal programs, meaning an inheritance could immediately disqualify a beneficiary from aged or disabled aid. We always advise clients to consult with a qualified Canadian tax advisor to navigate these complexities.

Finally, for deaths on or after April 1, 2025, a primary residence worth $750,000 or less (gross value) may qualify for a simplified transfer under AB 2016 (Probate Code § 13151), bypassing formal probate.

What makes a California will legally enforceable when it matters most?

In California, a last will and testament is reviewed under probate standards that focus on intent, capacity, and execution. Clear drafting reduces ambiguity, limits misinterpretation, and helps families avoid unnecessary conflict during estate administration.

To ensure the will functions as intended, the executor must understand their fiduciary obligations, while the family should be prepared for the court supervision required to enforce the document.

When a will is drafted with California probate review in mind, it becomes a stabilizing roadmap rather than a source of conflict. Clear intent, proper authority, and compliant execution protect both families and estates.
