John Anthony Castro is a colorful character. He entered several Republican primaries seeking the Presidential slot after failing to win the primary for a Senate seat representing Texas. He sued to have our once and future President Donald Trump be removed from the ballot on Fourteenth Amendment Section 3 grounds. As we can easily infer, those suits went nowhere. But more than anything, John Anthony Castro was a tax guy with a virtual practice with locations in four cities. Not anymore. Now he is resident in a Bureau of Prisons facility – the Federal Medical Center Fort Worth. On October 30, 2024, Judge Terry Means sentenced Castro to 188 months in prison, followed by one year of supervised release and restitution of $277,243, following his conviction on 33 counts of “Aiding and Assisting in the Preparation and Presentation of a False and Fraudulent Return." Does the sad story of John Anthony Castro hold any lessons for us? Perhaps.

When Your Client’s World Is Bigger Than the U.S.
A lot of client meetings still start with the same assumptions: W-2 in a U.S. state, mortgage nearby, a 401(k), maybe some RSUs, and a college-savings plan. Yet many of those “simple” clients now own an apartment in another country, freelance for a foreign company, or have parents wiring money from overseas. The tax code does not see those details as background color; it treats them as organizing facts. This is where citizenship, residency, and domicile quietly step onto center stage. For planners, the challenge is not memorizing every cross-border rule. It is knowing when a client is no longer “just domestic” and shifting your planning framework before you stumble into penalties, double taxation, or blown opportunities.
