States Can Tax Away Their Political Power

High-tax states have spent years losing residents and income to lower-tax competitors. If those trends continue, the next loss could be political power in Washington.

A new 2030 congressional apportionment forecast projects California losing four U.S. House seats after the next census. Texas would gain four seats and Florida would gain two, while Arizona, Georgia, Idaho, North Carolina, and Utah would each gain one. The forecast is not a guarantee of what the 2030 census will find, but it shows where current population trends are heading.

For states that have watched residents leave for lower-tax alternatives, the consequences are beginning to compound. Losing residents means losing workers, taxpayers, investment, and income. Eventually, it can mean losing representation in Congress and Electoral College votes as well.

Americans Have Been Voting With Their Feet

CFE has documented the economic side of this shift. The latest IRS migration data showed Florida gaining about $21 billion in net adjusted gross income from interstate migration, while California lost about $12 billion, New York lost about $10 billion, Illinois lost about $6 billion, and Massachusetts lost about $4 billion.

Those figures represent more than people changing addresses. When residents leave, they take income, spending, investment, and future tax revenue with them.

Tax policy is not the only reason Americans move. Housing costs, jobs, family considerations, weather, and other factors all play a role. But taxes are one part of the competition among states, and the differences can be substantial. California's top individual income tax rate reaches 13.3 percent. Florida and Texas levy no individual income tax on wages.

Americans are free to compare those economic environments and decide where they would rather live.

Population Loss Eventually Reaches Washington

The Constitution turns those individual decisions into political consequences through congressional reapportionment.

After every decennial census, the 435 seats in the U.S. House are divided among the states based on population. States growing faster gain political weight. States growing more slowly risk losing it.

The latest forecast illustrates how significant that shift could become. California is projected to fall from 52 House seats to 48, while Texas would rise from 38 to 42. Florida would move from 28 to 30. Several other faster-growing states would gain representation as well.

CFE previously highlighted projections showing congressional representation moving toward lower-tax, faster-growing states. The latest numbers reinforce that trend. State policymakers cannot control where Americans choose to live, and policies that make a state less competitive can have consequences far beyond its tax collections.

The Cost of Driving Taxpayers Away

High-tax states face a difficult cycle when residents and income leave. A shrinking tax base can put more pressure on the taxpayers who remain, particularly if state spending continues to grow. Higher burdens can then make competing states even more attractive.

California has provided an unusually clear example of the problem. The state has even become involved in litigation over its ability to tax certain income connected to people who have moved elsewhere. But trying to extend a state's tax reach does not solve the underlying competitive problem.

States have another option: make themselves more attractive places to live, work, invest, and build businesses.

The coming reapportionment fight is therefore about more than congressional maps. It is another measure of the competition among the states. Residents make millions of individual decisions about where to live, and over time those choices can redraw the balance of political power in Washington.

CFE Takeaway

States cannot assume their population, tax base, or political influence is permanent. Americans can move, and they continue to move substantial amounts of income toward lower-tax states.

If those migration patterns persist through the next census, some high-tax states could discover that driving away residents carries one more cost: fewer seats in Congress and fewer Electoral College votes.

States can tax away their economic competitiveness. Eventually, they can tax away some of their political power, too.
