States With No Income Tax
Nine states have no state income tax on wages: Alaska, Florida, Nevada, New Hampshire (taxes interest and dividends only until 2027), South Dakota, Tennessee, Texas, Washington (taxes capital gains above $250,000), and Wyoming. While these states save you from income tax, they may have higher property taxes, sales taxes, or other fees to fund state operations. Always consider the total tax burden — not just income tax — when comparing states.
States With Flat Tax Rates
Several states use a flat (single-rate) tax system where all taxable income is taxed at the same rate regardless of income level. As of 2026: Arizona (2.5%), Colorado (4.4%), Georgia (5.49%), Idaho (5.8%), Illinois (4.95%), Indiana (3.05%), Kentucky (4.0%), Michigan (4.25%), Mississippi (4.7%), North Carolina (4.5%), Pennsylvania (3.07%), and Utah (4.55%). Flat-tax states are generally simpler to file in but can be less progressive than bracket-based states.
States With Progressive Tax Brackets
California has the highest top marginal rate at 13.3% (for income above $1,000,000). Other high-tax progressive states include Hawaii (11%), New York (10.9%), New Jersey (10.75%), Oregon (9.9%), and Minnesota (9.85%). These states tax higher earners at higher rates — but most have multiple brackets, meaning moderate-income residents often pay much lower effective rates. New York's top rate only applies above $25 million; rates below $215,000 range from 4% to 6%.
How State Taxes Affect Financial Decisions
State income taxes influence major financial decisions: where to live in retirement (moving from CA to NV can save tens of thousands annually), where to establish business residency, and whether to accelerate or defer income. However, consider the full picture — states without income tax often have higher property taxes (Texas property tax rate is among the nation's highest), sales taxes, or insurance costs. For high earners, the income tax savings of a zero-tax state typically outweigh the other costs.
Reciprocity Agreements and Remote Work
Many bordering states have reciprocity agreements allowing residents who work across state lines to pay tax only in their state of residence (not where they work). Common agreements: WI–IL, PA–NJ, MD–VA–DC, and several midwest states. For remote workers, tax rules vary by state — some tax you based on where you physically perform the work, others based on your employer's location. Some states have 'convenience of the employer' rules that may tax remote workers even if they never set foot in the state.
