If you own property in Florida but live abroad, or if you are a U.S. citizen with assets, family, or a spouse outside the United States, your estate plan requires far more than a standard Last Will or Trust. International estate planning is a specialized area of law that blends U.S. tax rules, immigration status, foreign ownership laws, and international tax treaties into one coordinated strategy. When it is done right, it protects your family, minimizes taxes, and prevents assets from getting trapped in expensive cross-border probate or tax disputes.
The following is a brief overview of how international estate planning works from a Florida legal perspective.
Why International Estate Planning Is Different
U.S. estate planning is built around generous exemptions and spousal protections. However, when a foreign person or non-U.S. citizen spouse is involved, those protections change dramatically.
U.S. Persons vs. Foreign Persons
Under federal law:
- U.S. persons (citizens and domiciliaries) are taxed on their worldwide assets and receive a large estate tax exemption.
- Foreign persons (non-residents who are not U.S. domiciliaries) are taxed only on U.S.-situs assets, but they get a very small exemption.
Green card holders or Lawful Permanent Residents are a mix, i.e., (resident alien), are generally treated as a U.S. person for estate tax purposes. This means the U.S. may tax their assets held anywhere in the world with Exemption Thresholds: Starting January 1, 2026, the federal estate tax exemption for U.S. citizens and domiciled green card holders is projected to be approximately $15 million. Estates exceeding this value are subject to federal taxes of up to 40%.
In practical terms, which means:
- A non-U.S. resident who owns Florida real estate directly can face U.S. estate tax exposure even on modest property values—often with no meaningful tax shelter.
- Florida condominiums, rental homes, brokerage accounts, and even certain business interests are all considered U.S.-situs property for foreign owners.
Non-Citizen Spouses: The Hidden Estate Tax Trap
Many couples assume that leaving everything to a spouse avoids estate tax. That is true only when the spouse is a U.S. citizen.
When a spouse is not a U.S. citizen:
- The unlimited marital deduction does not apply
- Transfers at death can trigger immediate U.S. estate tax
- Gifts during life are subject to special limitations
This affects:
- Florida residents married to foreign nationals
- Snowbirds with international spouses
- International couples buying Florida real estate together
Without proper planning, a surviving spouse may owe estate tax just to keep the family home.
Why QDOTs Are Often a Last Resort
A Qualified Domestic Trust (QDOT) is sometimes used to delay estate tax when a non-citizen spouse inherits assets. But QDOTs:
- Are expensive to set up and maintain
- Require U.S. trustees and annual filings
- Still trigger estate tax later
- Restrict how the spouse can access the money
In Florida practice, better planning before death can often avoid the need for a QDOT entirely.
How Trusts and Entities Can Protect Foreign Owners
Proper structuring makes all the difference.
Instead of owning Florida real estate directly, many foreign clients use:
- Foreign corporations
- Carefully structured LLCs
- U.S. or foreign trusts
These tools can:
- Convert U.S.-situs assets into non-U.S. property
- Reduce or eliminate estate tax exposure
- Avoid Florida probate
- Provide privacy and asset protection
But these structures must be designed carefully. Poorly drafted foreign trusts or incorrectly owned LLCs can accidentally create new tax problems instead of solving them.
Estate Tax Treaties Can Change the Rules
The United States has estate tax treaties with several countries. These treaties can:
- Increase exemptions
- Prevent double taxation
- Change how property is classified
If you or your spouse has ties to a treaty country, your Florida estate plan should be designed around that treaty—not in ignorance of it.
Why Florida Clients Need Specialized Planning
Florida is one of the most popular destinations in the world for:
- International investors
- Retirees
- Snowbirds
- Global families
That makes international estate planning especially important here. A Florida-based lawyer who understands both U.S. tax law and international ownership rules can often save families hundreds of thousands of dollars and years of legal headaches.
The Bottom Line
If you have:
- A non-U.S. citizen spouse
- Property in Florida but live abroad
- Assets outside the United States
- Foreign trusts, companies, or heirs
You do not have a standard estate plan—you have an international one.
Consequently, international estate planning requires specialized legal and tax design to protect your wealth, your family, and your legacy across borders.
If you would like help structuring a Florida-based plan that works globally, an experienced estate planning attorney is needed to guide you.
