The concept of cost segregation began in the 1960s, when taxpayers argued specific components of real estate had a shorter life than the depreciation tables allowed (39 years for commercial property and 27.5 years for residential real estate). After decades of legal cases, the IRS provided rules and safe harbors in 1996 and 2002. Taxpayers now can use cost segregation and remain compliant with IRS regulations. The real question now is: Does a cost segregation study really reduce a taxpayer’s liability? And if so, by how much?

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.
