Income taxes in red versus blue states now sit at opposite ends of a widening gap: most Democratic-leaning states use graduated brackets that push top marginal rates as high as 13.3%, while most Republican-leaning states have moved to a single flat rate or charge no income tax on wages at all. Where you live, and increasingly where you work remotely, can be the difference between owing nothing on a state return and handing over more than a tenth of your top-dollar earnings.
How Blue States Tax Income
Blue states generally use graduated brackets. Income is split into tiers, and each tier is taxed at a progressively higher rate. Only the dollars inside a given bracket are taxed at that bracket’s rate, so moving into a higher bracket does not raise the tax on everything you earned below it. That is the most misunderstood feature of a progressive system, and it matters because the advertised “top rate” applies to a much smaller slice of most people’s income than they assume.
California has nine brackets for 2026, climbing to 12.3% on taxable income above $742,953 for single filers. An additional 1% Mental Health Services Tax on income over $1 million pushes the effective top marginal rate to 13.3%, the highest state-level rate in the country. Bracket thresholds are adjusted each year based on the California Consumer Price Index.1California Legislative Information. California Code Revenue and Taxation Code RTC Section 17054
New York works the same way. Its lowest 2026 bracket starts at 4% and rates climb to 10.9% for taxable income above roughly $1.08 million for single filers. Surcharges then push the effective rate to 11.1% on income above $5 million and 11.7% above $25 million.2New York State Department of Taxation and Finance.

Massachusetts layers a 4% surtax on taxable income exceeding roughly $1.08 million for 2025, with the threshold adjusted annually for inflation.3Mass.gov. Massachusetts 4 Percent Surtax on Taxable Income Combined with the state’s 5% base rate, top earners face an effective 9% on income above that line. These surcharges are worth paying attention to even if your ordinary income sits well below them, because a one-time event, like selling a business or exercising stock options, can push a normal year over the threshold.
How Red States Tax Income
Republican-led states have moved aggressively toward flat taxes: a single rate on all taxable income regardless of how much you earn. The appeal for legislators is simplicity and predictable revenue; the appeal for taxpayers is a shorter return with no bracket math.
North Carolina dropped to a flat 3.99% for tax years beginning in 2026, down from 4.25% in 2025 and 5.25% just a few years earlier.4North Carolina Department of Revenue. Tax Rate Schedules The legislature built in triggers for up to three additional half-point cuts, activated automatically when General Fund revenue clears certain thresholds. At its lowest, the rate could eventually reach 2.49%.5North Carolina General Assembly. North Carolina Major Tax Rates
Arizona consolidated its old brackets into a single 2.5% rate once state revenue met a statutory trigger.6Arizona Department of Revenue. Individual Income Tax Highlights Indiana charges a flat 2.95% on adjusted gross income for 2026, dropping to 2.90% in 2027.7Indiana Department of Revenue. Rates Fees and Penalties
The trend keeps accelerating. Since 2021, Georgia, Idaho, Iowa, Louisiana, Mississippi, and Ohio have either adopted flat rates or enacted phased conversions. Several of these are tied to revenue triggers, so the rate falls automatically as the state hits surplus milestones. Ohio is scheduled to implement a flat 2.75% in 2026, and Kansas has a contingent trigger that could bring its rate down to 4%.
States With No Income Tax on Wages
Eight states charge no income tax on wages or salary: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming. New Hampshire completed the list in 2025 after finishing a phased repeal of its interest and dividends tax.8New Hampshire Department of Revenue Administration.

Washington gets grouped with these states, but the picture is more complicated. Washington does not tax wages, but it imposes a capital gains tax on long-term investment gains. For returns due in 2026, the first $278,000 in long-term gains is exempt. Gains above that are taxed at 7% up to $1 million and 9.9% beyond.9Washington Department of Revenue. New Tiered Rates for Washington’s Capital Gains Tax For most wage earners, Washington still functions as a no-income-tax state. For anyone selling a business or realizing large investment gains, the bill can be substantial.
What No-Income-Tax States Charge Instead
Skipping income tax does not mean paying less tax overall. States without an income tax lean harder on property taxes, sales taxes, and excise taxes to fund schools, roads, and public services. Texas has one of the highest effective property tax burdens in the country, with property taxes consuming roughly 3.5% of income. Nevada and Washington both carry total state and local tax burdens above 8.5%, driven heavily by sales and excise taxes. Alaska sits under 5% partly because oil revenue subsidizes state spending.
Whether you come out ahead in a no-income-tax state depends on what you own, what you buy, and how you earn your money. A high salary and a modest home can save real money in Texas. An expensive home and moderate income might cost you more there than in a state with an income tax and lower property rates.
The SALT Deduction and What Your State Tax Really Costs
How much your state income tax actually costs you depends on whether you can deduct it federally. The state and local tax deduction was capped at $10,000 from 2018 through 2024, which hit high-tax blue states hardest because state income and property taxes there often blew past that cap by tens of thousands.
For 2025, the cap rose to $40,000 under the One Big Beautiful Bill Act, with a further adjustment to $40,400 for 2026. The higher cap phases down for taxpayers with modified adjusted gross income above $505,000 in 2026, and once fully phased out, the cap drops back to $10,000.10Internal Revenue Service.

For middle-to-upper-income taxpayers in progressive-tax states who itemize, this change narrows the real-world cost gap between living in a high-tax state and a low-tax one. Someone paying $25,000 in combined state income and property taxes now gets a much larger federal offset than under the old cap. Taxpayers in no-income-tax states see less benefit, because their deductible state taxes were more likely to fall below even the $10,000 limit.
Remote Work Can Undo the Savings
If you work remotely from a low-tax or no-tax state for an employer based in a high-tax state, you may still owe income tax to the employer’s state. Seven states apply a convenience-of-employer rule that sources remote income to the employer’s location rather than where the work is physically performed: New York, Pennsylvania, Delaware, Arkansas, Connecticut, Nebraska, and Massachusetts.
New York enforces this most aggressively. Its tax regulations treat a nonresident employee’s income as New York-sourced unless the out-of-state work was performed out of necessity for the employer, not personal convenience.11New York State Department of Taxation and Finance. New York Tax Treatment of Nonresidents and Part-Year Residents If you moved to Florida to escape New York’s income tax but your employer has a New York office you could use, New York’s position is that your full salary is still New York-sourced.
Most of these states recognize an exception when remote work is a genuine business necessity, such as no available office space or an employer mandate that similar positions work remotely. The burden of proof falls on the employer, not you. States outside this group generally tax nonresidents only on income physically earned within their borders.
Filing When You Live and Work in Different States
Living in one state and earning income in another means extra filing. Reciprocity agreements between neighboring states can simplify this by letting you pay tax only to your home state even if you commute across a state line. Pennsylvania, for example, has reciprocal arrangements with six neighboring states.
Without reciprocity, you typically file a nonresident return in the state where you earned the income and a resident return in your home state. Your home state usually credits you for taxes paid to the other state, so you are not taxed twice on the same dollars. The credit works, but you still file in both places and sometimes pay both upfront before reconciling.
How Different Income Types Get Sourced
Not all income follows the same rules across state lines. Wages are generally taxed by the state where the work is physically performed, subject to the convenience-of-employer exceptions above. Investment income, dividends, and gains from selling stocks or other intangible assets are typically taxable only in your state of legal residence. Real property is the major exception: if you sell land or a building in another state, that state can tax the gain regardless of where you live.
Moving Mid-Year
Moving between a progressive-tax state and a flat-tax state mid-year means filing part-year resident returns in both, splitting income by your exact move date. Income earned before the move is taxed by the old state; income after, by the new one. Allocation errors are a common audit trigger on interstate moves, so document the move date with a lease, utility transfer, or postal address change.
