State Income Tax Comparison

State Income Tax Comparison: TX/FL/WA vs. CA/NY

Nine states impose no income tax on wages, salaries, and most investment income: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. For high earners, retirees with large IRA withdrawals, and anyone with significant capital gains, the difference between living in a no-income-tax state and living in California or New York is not a marginal budget consideration—it's a material, ongoing, and compounding financial advantage.

Understanding exactly what the tax differential is, which income types are affected, and the residency requirements that actually establish tax domicile turns what sounds like a simple decision ("move somewhere cheaper") into a precise financial calculation.

THE INCOME TAX COMPARISON: WHAT'S ACTUALLY AT STAKE

California's income tax structure in 2024 reaches a top rate of 13.3% on income above $1 million (for single filers; lower thresholds for the 12.3% and 9.3% brackets). For a single Californian earning $300,000:

Federal income tax: approximately $82,000

California income tax: approximately $24,000 (effective rate around 8%) Total: approximately $106,000

The same $300,000 in Texas: federal income tax unchanged at $82,000; state income tax $0. Annual tax savings: $24,000.

Over 20 years, $24,000 per year invested at 6% return: approximately $935,000 in additional wealth—generated solely by state tax residence, not by any investment strategy or income change.

California additional taxes:

- 1% mental health surcharge on income above $1 million - SDI (State Disability Insurance) payroll deduction of 1.1% on all wages (no wage cap in 2024)

New York State imposes income tax at rates up to 10.9% (income above $25 million for single filers; 9.65% above $1.08 million). New York City adds a city income tax of up to 3.876%. A high earner living in New York City faces combined state and city income tax rates approaching 14.8%—exceeding California's top rate.

Washington State: No income tax on wages or investment income. Note: Washington passed a 7% capital gains tax in 2022 (affirmed by the state Supreme Court in 2023) on long-term capital gains above $262,000 per year. This makes Washington partially exceptional among no-income-tax states for high capital gains earners.

Florida: No income tax of any kind on any income type (including capital gains). The most comprehensive income tax advantage among the large, desirable states.

Texas: No income tax on wages, salaries, or capital gains, but significantly higher property taxes than California, New York, or Florida—which partially offsets the income tax savings for homeowners.

THE RETIREMENT INCOME DIFFERENTIAL: WHERE THE TAX GAP WIDENS

For retirees with substantial traditional IRA or 401(k) balances, the state income tax comparison is even more consequential because retirement withdrawals that represent ordinary income are taxed by states that have income taxes:

A California retiree taking $150,000 per year from traditional IRA withdrawals pays California income tax on those withdrawals at approximately 9.3% effective rate—$14,000 per year. A Florida retiree taking the same $150,000 pays $0 to Florida.

Social Security: Most states that have income taxes exempt some or all Social Security benefits. California exempts Social Security income entirely from state taxation. New York also exempts Social Security. This makes the Social Security comparison between states less consequential than the comparison for IRA withdrawals, capital gains, and other ordinary income.

Pension income: State treatment of pension income varies significantly. Many states exempt public sector pensions (police, firefighter, teacher) from state income tax. Some states (Pennsylvania, Illinois) exempt all pension income. Retirees with pension income should verify their specific pension type's treatment in both the current and potential destination state.

THE CAPITAL GAINS TAX DIFFERENTIAL

California taxes capital gains at ordinary income rates—up to 13.3%. There is no preferential capital gains rate at the California level. A California resident who sells a business at a $2 million gain pays $246,000 in California capital gains tax (at 12.3% rate for this income level) in addition to federal capital gains taxes.

The same sale in Texas or Florida: $0 in state capital gains tax.

For retirees who have accumulated low-basis stock portfolios, rental properties, or business interests, the state of residence at the time of sale determines whether a significant additional tax is owed. Moving from California to Nevada before selling appreciated assets is a legitimate and commonly practiced tax strategy—but it requires genuine domicile establishment, not just temporarily renting an address.

THE DOMICILE QUESTION: ESTABLISHING ACTUAL TAX RESIDENCE

State tax agencies—particularly California's Franchise Tax Board (FTB) and New York's Department of Taxation—aggressively audit residency claims. A person who claims to have moved from California to Nevada while maintaining California home ownership, employment relationships, and family connections will face scrutiny.

The legal standard is "domicile"—the place you intend to make your permanent home. Multiple factors are considered:

Location of primary residence: Where do you sleep most nights? Is the new state home your actual residence or a second address?

Location of employment and income sources: Where do you work? Where is your employer? Remote workers employed by California companies may still owe California income tax on income attributable to California.

Location of close personal relationships: Where is your immediate family? Where do you attend religious services, civic organizations, and social activities?

Location of significant possessions: Where are your cars registered? Where are your financial accounts held? Where do you receive mail?

Days in each state: California and New York track cell phone location data, social media check-ins, credit card transactions, and other location evidence when auditing residency claims. The FTB has been known to request detailed day-by-day calendars from residency audit targets.

The safe harbor that most practitioners use for California: spending fewer than 546 days in California over any consecutive 24-month period during a temporary absence establishes a presumption of non-California domicile. More importantly, establishing genuine primary residency in the destination state—driver's license, vehicle registration, voter registration, banking relationships, and genuine connection to the new community—is the foundation of a defensible domicile claim.

REMOTE WORK AND STATE INCOME TAX: THE COMPLICATIONS

Remote workers employed by companies in high-tax states face additional complexity: some states (New York, New Jersey, Pennsylvania) apply the "convenience of the employer" doctrine. If a New York employer has a New York office, and an employee works remotely in another state for the employee's convenience (not because the employer requires it), New York may still claim taxation of that income.

A California-based employee who moves to Texas and works remotely for their California employer may still owe California income tax on income sourced to California work, under California's rules. The specifics depend on the nature of the work, the employer's location, and whether the work creates nexus in the new state.

Remote workers making a multi-state move for tax purposes should consult a tax attorney or CPA specializing in multi-state taxation before assuming the move eliminates the high-tax state's claim on their income.

THE TOTAL TAX PICTURE: INCOME + PROPERTY + SALES

The income tax comparison understates the full tax differential because property taxes and sales taxes vary significantly by state:

Texas: No income tax, but among the highest property tax rates in the country—averaging 1.5% to 2.5% of assessed value annually. A $500,000 home in Texas might generate $10,000 to $12,500 in annual property taxes. California's Proposition 13 caps property tax at 1% of assessed value plus limited annual increases—a long-term California homeowner may pay $4,000 in annual property taxes on a $1.5 million home because the assessment was frozen at 2001 purchase values.

Florida: No income tax, property taxes around 0.8% to 1.5% of assessed value, lower than Texas. Florida also has a Homestead Exemption ($50,000 off assessed value for primary residence) and the Save Our Homes cap limiting assessment increases to 3% per year.

No sales tax states: Oregon (no sales tax), New Hampshire (no sales tax or income tax on wages), Montana (no sales tax).

High sales tax states: California (7.25% base rate plus local additions up to 10.75%), Louisiana (average combined rate approximately 9.55%), Tennessee (9.55%).

The total tax burden analysis—combining income, property, and sales taxes relative to income—produces different rankings than income tax alone. The Tax Foundation publishes annual state-by-state total tax burden calculations that provide a more complete picture than income tax rates in isolation.

QUALITY OF LIFE AND COST-OF-LIVING OFFSETTING FACTORS

The income tax savings from moving to Texas or Florida are real. So are the higher costs that may partially offset them:

Housing in desirable areas of no-income-tax states: Austin, TX and Miami, FL experienced dramatic price appreciation as remote workers and retirees relocated. Austin median home prices rose from approximately $300,000 in 2019 to over $500,000 in 2022 before moderating. The housing cost increase may consume years of tax savings.

Higher property taxes in Texas: A homeowner who moves from California (where Prop 13 caps their $1.5M home's taxes at $15,000/year) to a $750,000 home in Texas may pay $11,000 to $18,000 in Texas property taxes—potentially eliminating much of the income tax saving on a moderate income.

Infrastructure, climate, and services: Florida's hurricane risk, Texas's power grid vulnerability (demonstrated in the February 2021 winter storm), and other geographic and infrastructure factors are real quality-of-life and financial risk considerations that belong in the analysis.

The complete geographic arbitrage analysis includes the income tax differential (the primary financial driver), property tax comparison, cost-of-living adjustment, housing market dynamics, and genuine lifestyle factors—not just the income tax headline number.
