According to new IRS migration data, there is a significant shift of Americans and billions in taxable income from several coastal blue-state strongholds to Southern and Sun Belt states, which is reshaping economic and political power ahead of the 2026 midterms. This migration is impacting housing markets, state economies, congressional representation, and the balance of power in the United States [1].
Texas and Florida led the nation in inbound migration between 2022 and 2023, with Texas gaining more than 56,000 residents and Florida adding over 55,000 income tax filers. Florida also saw an increase of approximately $20.6 billion in taxable income, while Texas gained $5.5 billion. Other top destinations for interstate movers included North Carolina, South Carolina, Tennessee, and Arizona, highlighting a broader population boom across the South and Sun Belt [1].
When adjusted for population size, South Carolina posted the nation’s largest gain from domestic migration at 1.12%, driven by more than 29,000 incoming households bringing about $4.1 billion in taxable income. In contrast, California experienced the largest outbound losses, with over 100,000 income tax filers and nearly $12 billion in taxable income leaving the state. New York lost roughly 72,000 households and nearly $10 billion in taxable income, while Illinois and New Jersey shed about $6 billion and $2.6 billion, respectively [1].
Experts attribute this migration boom to affordability pressures, with households moving toward lower-cost, lower-tax states in the South. Nicole Fox, a policy analyst at the Tax Foundation, stated, "While tax friendliness is not the sole determinant of where one chooses to live or start a business, states experiencing net in-migration tend to have more competitive tax structures and lower overall costs of living." The migration trends are reshaping state economies, labor markets, and housing demand, as fast-growing Sun Belt states absorb new residents, businesses, and taxable income, while states with sustained outbound migration face shrinking tax bases and slower population growth [1].
CONCLUSION
IRS migration data highlights a powerful wealth and population shift toward Southern and Sun Belt states, driven by affordability and tax advantages. This trend is expected to continue reshaping state economies, labor markets, and political power, while states with outbound migration face economic and demographic challenges.
