Overview
- New county-level IRS migration figures show the largest net losses of interstate tax filers are concentrated in California and New York, while fast-growing counties in Arizona, Texas, Washington and Nevada show the biggest gains.
- Los Angeles County led the nation with a net loss of 17,496 tax filers who took about $1.9 billion in adjusted gross income with them when they moved to other states.
- Manhattan gained more interstate filers than any other county but still lost roughly $1 billion in reported income, a sign that newcomers on average earned less than those who left.
- Economists and conservative commentators point to taxes, housing costs and jobs as key drivers of the moves, and reporting shows some outlets link departures to local Democratic policies while others stress broader affordability and opportunity factors.
- The IRS data measure movements of tax filers and adjusted gross income and do not prove motive, but the outflows raise clear fiscal risks for funding schools, public safety and infrastructure and could force policy debates over taxes and services.
