Navigating Estate Tax Exemptions for Non-Citizen Spouses
When a California couple includes a non-citizen spouse, estate planning becomes more complex, particularly regarding the federal gift and estate tax. While California doesn’t impose a state estate tax, the federal rules create potential pitfalls worth understanding and overcoming.
What Is the Unlimited Marital Deduction?
Under U.S. tax law, married couples who are both U.S. citizens can transfer unlimited assets to each other without paying gift or estate taxes. This is called the unlimited marital deduction. But if one spouse is not a U.S. citizen, this benefit doesn’t apply. In California, if a U.S. citizen gives assets to a non-citizen spouse, those assets may be fully taxed after death at rates up to 40% if they exceed the allowed exemption.
What Exemptions Still Apply?
Gift Tax Annual Limit
U.S. citizens can give up a set amount to a non-citizen spouse each year without gift tax. That limit is $190,000 in 2025. Higher than the standard $18,000 gift tax exclusion, but still a cap. Exceed it, and you’ll trigger gift tax liability.
Federal Estate Tax Exemption
In 2025, the federal estate tax exemption is $13.99 million per individual or $28 million for married couples. This exemption cannot be transferred to a non-US citizen spouse, so your combined estate tax cushion is cut in half.
How Can a Qualified Domestic Trust Be Used?
When a married couple includes a non-citizen spouse, the usual unlimited estate tax exemption for transfers between spouses does not apply. To solve this issue, U.S. tax law allows the creation of a Qualified Domestic Trust (QDOT). This type of trust helps non-citizen spouses receive assets in a way that delays or reduces estate taxes.
When a U.S. citizen spouse dies, their assets can go into a QDOT instead of passing directly to a non-citizen spouse. Non-citizen spouses can receive income from the trust without paying estate taxes, but if they take out the principal, estate taxes may apply.
The main benefit of a QDOT is that it allows the estate to qualify for the marital deduction, which usually isn’t available when one spouse isn’t a U.S. citizen. This delays estate taxes until the money is withdrawn, helping the surviving spouse manage their finances. If the non-citizen spouse later becomes a U.S. citizen, the trust’s remaining assets can usually be released tax-free.
It’s a good idea to set up the trust in advance or include it in a will to avoid delays. With proper planning, a QDOT helps protect assets and reduce estate taxes for international couples.
What Happens When the Non-Citizen Spouse Dies First?
If the non-citizen spouse predeceases the U.S. citizen, the surviving spouse can fully utilize their own exemption and unlimited marital deduction. U.S. citizens can transfer their exempt amount and unused spousal exemption to the surviving spouse via the portability election. In planning, spouses should consider whether the non-citizen dies first or second and optimize for both scenarios.
Watch Out for Jointly-Owned Property
Like in other community property states, married couples often own real estate, bank accounts, and investments together in California. When one spouse passes away, the surviving spouse receives a 50% step-up on jointly owned property. This means the value of the deceased spouse’s share is adjusted to its current market value at the time of death. The step-up helps reduce capital gains taxes if the property is later sold.
International Assets and Situs Rules
The U.S. estate tax only applies to assets with a U.S. situs, which means the property is located in the United States for legal and tax purposes. This includes things like U.S. real estate, American stocks, and businesses based in the U.S. Assets situated in another country are considered foreign situs assets and are generally governed by the estate laws of that country instead. For non-citizen spouses who own property abroad, creating a separate will or trust to handle those foreign assets and ensuring their U.S. and international estate plans work together is essential. This helps avoid double taxation and ensures the property is passed on as intended. It’s also good to check whether a tax treaty exists between the U.S. and the other country, as treaties can sometimes reduce or eliminate estate taxes on foreign assets. Planning carefully for U.S. and foreign property can help protect your family’s financial future.
Five Key Steps for California Couples with a Non-Citizen Spouse
1. Get Advice from an Estate Planning Attorney
Work with an attorney who understands both U.S. and international tax laws. They can help you create a plan that protects your assets and avoids costly mistakes.
2. Keep Records of Financial Contributions
Document who paid for what, especially for jointly owned property. This helps prevent the IRS from unfairly taxing the entire value of shared assets.
3. Set Up a Qualified Domestic Trust (QDOT)
A QDOT allows assets to pass to a non-citizen spouse without immediate estate taxes. The surviving spouse can access income from the trust, and taxes apply only if the principal is withdrawn.
4. Use Annual Gift Exemptions and Portability
Give up to $190,000 per year to a non-citizen spouse tax-free. File IRS Form 706 after death to transfer any unused estate tax exemption if the surviving spouse is or becomes a U.S. citizen.
5. Review and Update Your Plan
Laws, finances, and family situations change. Update your estate plan regularly to keep it current and effective.
