Highest State Income Tax at $100K
Every US jurisdiction ranked by the state income tax a single filer owes on $100,000 of taxable income. A high top marginal rate does not decide this, where the brackets bite does.

The highest-burden answer
Oregon carries the heaviest state income-tax line at $100K of taxable income - $8,431, about 50% of the federal tax on the same income. The states at the top of this table run progressive schedules whose upper brackets are reached well before $100K; the highest top marginal rate (California) sits only mid-table here, because that rate applies far above $100K.

Why these states rank highest
The heaviest state-tax lines at $100,000 belong to states whose progressive brackets climb steeply at middle incomes, not to the states with the highest headline top rate. Oregon leads at $8,431: its schedule reaches the upper-8% range well below $100K, and with no general sales tax the income tax carries more of the load. The District of Columbia, Maine, Hawaii, and Minnesota follow for the same reason, high rates that arrive early. Source: Tax Foundation, 2026 State Individual Income Tax Rates and Brackets.
This is why the top-marginal-rate leaderboard and the burden leaderboard disagree. California posts the nation's highest top rate, 13.3% above $1 million, including the 1% Mental Health surtax, yet its state tax on $100K of taxable income is about $5,953, mid-table, because almost all of a $100K income is taxed in California's lower brackets. New York (top rate 10.9%) lands similarly. Source: California Franchise Tax Board / New York State Department of Taxation and Finance, 2026 schedules.
Massachusetts is the clearest example of a high top rate that barely touches a $100K filer: its 5% flat rate plus the 4% "Fair Share" surtax above $1.083M means a $100,000 income is taxed at a flat 5%, far down this ranking. Source: Massachusetts Department of Revenue, 2026 surtax guidance.
State tax as a share of total tax
For the states at the top of this table, the state income-tax line is a meaningful fraction of the federal bill. Oregon's $8,431 equals roughly 50% of the $16,914 federal income tax on $100,000 of taxable income. A no-income-tax state shaves that entire line to zero, which is why relocation math so often turns on the income-tax column even when property and sales taxes partly offset it.
What matters most for an incremental decision (a raise, a bonus, a Roth conversion) is the combined marginal rate. A single filer at $100K in a high-burden state typically faces a 22% federal marginal rate plus a state marginal rate of 6–9% plus 1.45% Medicare, roughly 30–33% on the next dollar. The calculator shows your exact marginal and effective rates side by side.
