Changes in US Tax Laws Over 20 Years

Over the past two decades, US tax laws have undergone significant transformations, particularly in the realm of international tax compliance. The introduction of the Foreign Account Tax Compliance Act (FATCA) marked a pivotal shift, greatly expanding the IRS’s enforcement capabilities and increasing the reporting obligations for US taxpayers with foreign financial interests.

As global financial transparency has become a priority, the IRS has placed heightened scrutiny on the reporting of overseas assets, implementing stricter compliance measures and enhanced enforcement efforts. Today, US taxpayers—whether residing domestically or abroad—face a complex and evolving regulatory landscape, requiring careful navigation to ensure compliance and mitigate potential risks.
