California Brain Drain: How Much Income Is Leaving the State

California lost an estimated $24 billion in adjusted gross income to other states between 2022 and 2024, according to IRS migration data. The people leaving aren't random, they're disproportionately high earners, and they're taking taxable income California can't afford to lose.

The Scale of the Exodus

IRS Statistics of Income data consistently shows California as one of the largest net losers of AGI in the country. For the most recent full reporting period available (as of late 2025), California saw a net outflow of roughly 120,000 tax filers per year, but the dollar loss per departing household skews dramatically upward.

The average AGI of a household leaving California is significantly higher than the average AGI of households arriving. That gap matters because California's budget is built on top earners. The top 1% of California filers generate roughly 40% of all state income tax revenue. Losing 10,000 high-income filers has an outsized effect on state finances compared to losing 10,000 median-income filers.

Where the Money Is Going

Texas and Florida absorb the largest share of California's departing income. Nevada, Arizona, and Tennessee round out the top five destinations. None of those states has a personal income tax.

This isn't coincidental. California's top marginal income tax rate sits at 13.3%, the highest in the nation. A household earning $1 million in California owes the state $133,000 or more in income tax alone, before federal taxes, before property taxes, before the state's 7.25% base sales tax rate. Moving to Texas or Florida zeroes out that state income tax bill entirely.

What's Actually Pushing People Out

Tax rates are the most cited reason, but they're not the only one. California's median home price as of late 2025 hovered around $800,000 statewide, with coastal metros like San Francisco and Los Angeles well above $1 million. Property taxes are partially softened by Proposition 13, which caps assessment increases at 2% per year for existing owners, but new buyers absorb the full assessed value at purchase.

Then there's the cost-of-living compounding effect. Electricity rates in California are among the highest in the continental United States, averaging over 30 cents per kilowatt-hour in 2026 after successive rate increases tied to wildfire liability and grid upgrades. Gasoline taxes add roughly 68 cents per gallon on top of federal taxes. These aren't trivial numbers for families evaluating whether to stay.

High earners in tech and finance, historically tethered to Bay Area offices, now have remote and hybrid arrangements that make geography optional. When location becomes optional and the state takes 13.3 cents of every dollar above $1 million, the calculus shifts fast.

What California Loses Beyond Tax Revenue

Every high earner who leaves takes more than their W-2 income. They take capital gains realizations, investment income, estate planning dollars, and philanthropic activity. California taxes long-term capital gains as ordinary income, meaning a founder selling $10 million in stock pays 13.3% to the state on top of the 20% federal rate. A Texas resident pays zero to the state on that same transaction.

For anyone sitting on significant unrealized gains, that difference alone can justify a move well before the actual liquidity event. The planning often happens years in advance. See our Capital Gains Tax by State: A Full Breakdown to run those numbers for your specific situation.

California has also struggled to replace departing income with equivalent new arrivals. Immigration and domestic in-migration still bring people to the state, but the income profile of arrivals doesn't match the income profile of departures.

Key Takeaways

• California's net AGI outflow reached an estimated $24 billion over the 2022-2024 period, with Texas and Florida capturing the largest share of departing income.
• The state's 13.3% top marginal income tax rate is the highest in the nation, and a $1 million earner saves over $133,000 per year by moving to a zero-income-tax state.
• California taxes capital gains as ordinary income, meaning a $10 million liquidity event costs $1.33 million in state taxes that a Texas or Florida resident avoids entirely.
