New IRS migration data show Palm Beach County, Florida — President Donald Trump's hometown — has become the biggest single destination for taxpayer wealth moving between US counties, attracting more than $3 billion in taxable income from households relocating from other states. The figures underline a broader pattern of wealthy Americans and businesses shifting from higher-tax, typically Democratic-led states towards lower-tax, Republican-led areas of the country, a trend that has accelerated in recent years and carries significant implications for state tax bases and local economies.

The report highlights Palm Beach County as recording the largest net gain of any county nationwide, reinforcing south Florida's reputation as a magnet for relocating high earners, retirees and businesses drawn by the state's favourable tax regime and lifestyle appeal. The article frames this as part of a wider narrative of population and wealth flowing towards Sun Belt and lower-tax states, with Trump's adopted home county now positioned as the standout example of that shift.
