Jessica, a self-employed consultant, was thrilled when she found a viral TikTok video promising a “little-known” tax trick. The video claimed she could get a huge refund by claiming a special Fuel Tax Credit and even writing off her family’s beach vacation as a business expense. Following the advice, Jessica filed an amended tax return and waited eagerly for a windfall. A few months later, instead of a refund check, Jessica received a stern IRS notice. Her so-called credits were disallowed, her refund was denied, and she now faced penalties. Jessica isn’t alone. Every tax season, well-intentioned taxpayers get lured by false tax advice on social media, only to end up in trouble. As tax professionals, we often meet panicked clients like Jessica who need our help to untangle the mess.

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.
