Highest Income Tax States 2026: Top 10 by Rate and Effective Burden

US state income tax ranges from 0% (Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Alaska, New Hampshire on wages, Tennessee on wages) to 13.3% (California’s top marginal rate). But top marginal rates are often misleading — California’s 13.3% rate only applies on income above $1 million for single filers. Most $100,000–$300,000 earners in California pay an effective state rate of roughly 5–8%, not 13.3%.

Understanding which states actually cost the most at typical income levels requires looking at effective burden — the actual percentage of total income paid in state taxes after deductions and credits. This guide provides both rankings: top marginal rate (useful for ultra-high earners and planning purposes) and effective burden at $100,000 income (the more practical benchmark for most professionals). It also addresses the question every high earner in a high-tax state asks: is the economic opportunity and quality of life worth the tax premium?

Top 10 States by Marginal Income Tax Rate

Top marginal rates apply only to income above the specified thresholds. High marginal rates primarily affect ultra-high earners and are often irrelevant for most residents.

Effective Burden at $100K Income: The More Useful Ranking

Effective burden is the actual percentage of $100,000 gross income paid in state income tax after standard deductions and personal exemptions. This is the more relevant comparison for most professionals and families.

Are High-Tax States Worth the Premium?

The economic and quality-of-life question matters as much as the raw tax number. High-tax states are expensive for a reason: they typically offer the largest economies, most lucrative job markets, and strongest educational and cultural institutions in the country.

The California Case

California is home to Silicon Valley (the world’s largest tech ecosystem), Hollywood (global entertainment industry), and the nation’s largest agricultural economy. San Francisco and Los Angeles offer average tech salaries of $180,000–$300,000+ — a salary premium that far exceeds the state tax disadvantage versus Texas or Florida for most workers. A software engineer earning $250,000 in San Francisco pays ~$18,000–20,000 more in state income tax than a comparable role in Austin. But if the California role pays $280,000 versus $200,000 in Austin, the pre-tax salary premium dominates. The tax comparison matters most for earners with portable income (remote workers, investors, business owners) who can capture the California salary premium without being California tax residents.

New York City: The Extreme Case

New York City combines New York State income tax (up to 10.9%) with New York City local income tax (up to 3.876%), producing the highest effective state+local income tax burden in the nation for high earners in the city — effectively 14%+ combined at top incomes. Yet NYC maintains one of the world’s most concentrated pools of finance, law, media, and professional services employment. The premium for NYC careers is real, but the tax cost at $300,000+ income is substantial. A $500K earner in New York City pays about $52,600 in combined state+city income tax (single filer, wages only, before NYC refundable credits) versus $0 in Texas or Florida — a $52,600/year difference that, over a career, is transformative wealth.

Migration Trends: Who Is Leaving and Where They Go

California has had net domestic out-migration every year since 2020 (about 240,000 residents in the year to July 2024, per Census Bureau estimates). New York and Illinois have also had net domestic out-migration in recent years. The migration pattern is concentrated among high earners and retirees — the groups most sensitive to income and property tax costs. Lower-income residents are less mobile and more dependent on the services high-tax states fund.

Property Tax: Often Overlooked in High-Tax State Comparisons

New Jersey and Illinois are tied for the nation’s highest effective property tax rates (~1.88% of home value), meaning a $600,000 home generates ~$11,280/year in property taxes. New Hampshire: ~1.50% (but no income or sales tax). Connecticut: ~1.54%. By contrast, California’s Proposition 13 caps property tax increases — a longtime California homeowner may pay well below market rate in property tax. Total tax burden comparisons that include property tax sometimes re-rank states in non-obvious ways.

Departure Planning for High Earners

For high earners seriously considering leaving a high-tax state, the process is more involved than simply moving — particularly for California and New York, which aggressively pursue residents who attempt to change domicile.

California Domicile and Audit Risk

California Franchise Tax Board (FTB) is notoriously aggressive in auditing high earners who claim to have left California. Key rule: California taxes residents on worldwide income. You are a California resident if you are in California for other than temporary or transitory purposes. If you move to Nevada or Texas but maintain a California home, California clients, California business activities, or regularly return to California, the FTB may assert continued California tax residency. To successfully establish Nevada/Texas domicile: sell or rent out your California home (do not maintain a California residence); keep your time in California below nine months a year (more than nine months creates a presumption of residency, FTB Publication 1031); change voter registration, vehicle registration, professional licenses, and primary bank accounts to the new state; establish a physical home and ties in the new state.

New York: Similar Audits Plus Statutory Resident Rule

New York also pursues departed high earners aggressively via its statutory resident rule: if you maintain a permanent place of abode in New York AND spend more than 183 days/year in New York, you are taxed as a New York resident even if you are domiciled elsewhere. Many NYC professionals who “move” to Florida while keeping their Manhattan apartment continue to be New York tax residents under this rule. Solution: give up the New York apartment entirely, or ensure you spend 183 or fewer days in New York.

Annual Savings at $300K+ From Moving

High earner relocating from California to Texas (no state income tax): at $300,000 income, California effective rate ~7.9% = ~$23,700 savings. At $500,000: California effective ~8.7% = ~$43,700 savings. At $1,000,000: California effective ~10.2% = ~$102,500 savings. These savings compound over decades and, invested, represent millions in wealth differential over a career. For portable income earners (investors, business owners, remote workers, retirees), state tax arbitrage is one of the highest-return financial moves available.
