Why do high-tax states affect migration patterns?

The short answer

The popular narrative holds that wealthy households flee high-tax states in large numbers, eroding state tax bases and forcing rate cuts. Empirical work using U.S. federal tax return microdata paints a much more restrained picture: annual outmigration of top earners from high-tax states is only marginally above the baseline outmigration rate of the general population.

The reason is straightforward. Top earners are typically tied to their state by employment, business relationships, family, professional networks, and non-portable industry ecosystems (finance in New York, tech in California, biotech in Massachusetts). The tax advantage of moving to a lower-tax state must overcome all of these frictions.

The clear exception is retirees. Once employment ties are cut, discretion rises sharply, and the pattern of Florida, Texas and other no-income-tax states absorbing retirement migration is empirically robust and long-standing.

What the data shows

The Young-Varner line of work is the most rigorous empirical inquiry into millionaire migration.

The empirical context (Young-Varner ASR 2016; earlier Young 2012; IRS SOI):

• Young and Varner’s 2016 American Sociological Review study, using thirteen years of federal tax return microdata, found the annual millionaire migration rate at approximately 2.4% — only marginally above the 2.2% rate for the general population
• The elasticity of top-earner interstate migration to state tax rates was small and often statistically indistinguishable from zero for prime-age workers
• Kleven, Landais and Saez (2013) studied European football migration and found much higher elasticities in that population, precisely because the industry is unusually portable
• Retiree migration data from IRS county-to-county flow files show a durable, decade-long pattern of movement to Florida, Texas and other low-tax states

The exception that nuances the picture: business owners at the point of a large liquidity event (sale of a business, IPO exit) show elevated tax-motivated migration in the surrounding years. The one-time realisation dwarfs the frictional costs of relocation for that specific event, unlike the ongoing income of an employed executive.

Why it happens — the macro mechanism

Three mechanisms explain the empirical modesty of tax-driven migration.

Channel 1 — The frictional cost of relocation. Moving a household imposes real costs: search, moving expenses, spousal employment disruption, children’s schools, social capital. For a prime-age earner with a $500K income, saving 5-8 percentage points on state tax is meaningful but not decisive against these frictions. The break-even calculation typically requires either extreme income or extreme mobility.

Channel 2 — The industry-anchoring effect. This is the underappreciated nuance. Top earners cluster in geographically concentrated industries — finance in New York, technology in the Bay Area and Seattle, entertainment in Los Angeles, biotech in Boston. The industry ecosystem generates a wage premium and an option value of career mobility that would be sacrificed by relocation to a low-tax but industry-thin state. Young-Varner’s evidence is consistent with industry ties dominating tax considerations for the active-worker population.

Between the two active channels, a short bridge: the retiree case sits outside these frictions because both employment ties and industry-cluster premia have vanished.

Channel 3 — The retiree exception. Once employment ends, the industry-anchor loosens and the frictions of relocation compete only with lifestyle and family considerations. Retirees with substantial assets and no state-tied employment show migration patterns that clearly respond to state tax gradients, particularly to no-income-tax states like Florida.

Synthesis by regime: in the prime-age regime with strong industry anchoring, tax-motivated migration is small and often statistically zero. In the retiree regime with no employment ties, the elasticity is meaningful and produces the observed decade-long flow to low-tax states. In the transition regime (approaching retirement or just after a business sale), individual behaviour is highly variable, with a fraction relocating specifically to capture tax savings on lump-sum realisations. The transition parameter is the strength of employment and industry ties.

The tax flight narrative is largely a myth for prime-age workers and largely accurate for retirees — and the two must not be conflated.

What it means for different economic actors

Prime-age high earners should treat state tax as one input among many rather than the dominant relocation driver. The empirical evidence suggests the tax savings are typically insufficient to overcome career, family and industry-network costs.

Retirees planning post-work location face genuine and often decisive tax gradients. State income taxes, state estate taxes, retirement-income exemptions, and cost of living together create differences that can affect lifetime after-tax wealth by material amounts.

Business owners approaching a large liquidity event face an intermediate case. The one-time nature of a sale or IPO exit can justify pre-event relocation to lock in the low-tax state, and the empirical evidence shows this behaviour is measurable in tax data.

A common error is to treat the tax-flight narrative as uniformly applicable and to base state fiscal policy debates on the aggregate migration rate. The heterogeneity across life stages and income sources is the empirical story that matters.

Frequently asked questions

Why is the millionaire migration rate not larger given the tax differentials?

The straightforward economic incentive — moving to a lower-tax state raises after-tax income — must overcome real frictions: search costs, family disruption, spousal careers, professional networks, and industry-cluster premia. For prime-age earners in industries geographically concentrated, these frictions typically dominate. Young and Varner’s ASR 2016 evidence shows the aggregate migration rate is only marginally above baseline.

How does the retiree case differ from the working-age case?

Retirees have shed the employment tie, which is the largest single friction. Their remaining anchors are family, lifestyle, and cost of living. State tax gradients — particularly zero-income-tax states like Florida and Texas — can meaningfully affect lifetime after-tax wealth without imposing career costs. The empirical migration flows are consistent with this framing.

Do state tax rate changes affect the elasticity meaningfully?

Modestly for prime-age earners, and more for retirees. Studies of specific state tax reforms (New Jersey’s 2004 millionaire tax, California’s 2012 Proposition 30) find small but detectable elasticities of top-earner migration, well below the rhetoric of major state fiscal debates. The one-time-liquidity-event case (business sale) is an important exception, where behaviour is more responsive.
