How State Income Taxes Work in the U.S.
State income tax is the portion of your paycheck withheld by your state government. Unlike the uniform federal income tax system, each of the 50 U.S. states sets its own rules — resulting in dramatically different tax burdens depending on where you live and work.
Beyond wage income, state taxes vary in what they include: some states tax all ordinary income, others exempt pension income, military pay, or Social Security benefits. Some impose no income tax at all, while others have rates exceeding 13%.
Understanding your state's tax structure is essential for accurate paycheck planning, especially if you're considering relocating, negotiating a salary, or evaluating a remote work arrangement.
The 9 States With No Income Tax in 2026
Nine states collect zero state income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Living in a no-tax state can save a worker earning $80,000 anywhere from $2,000 to $10,000+ per year compared to high-tax states like California or New York. However, these states often offset lost revenue through higher property taxes, sales taxes, or user fees.
Washington State: Note that Washington has a 7% capital gains tax on long-term gains above $250,000, introduced in 2023 — but this does not apply to wages.
New Hampshire: No tax on wages or salaries. Interest and dividend income was taxed at 5% but fully phased out by January 1, 2025.
Tennessee: Previously taxed investment income (Hall Tax) — fully repealed as of 2021. No income tax of any kind.
Flat-Rate States: Simple, Predictable Tax
Flat-rate states apply the same percentage to all taxable income, regardless of how much you earn. This makes paycheck calculation straightforward — your effective state rate equals the statutory rate.
Colorado: 4.40% flat rate (reduced from 4.55% in 2023). Residents may claim a Colorado Earned Income Credit.
Illinois: 4.95% flat rate, no standard deduction. Illinois does not tax Social Security, military pay, or pension income from most government plans.
Indiana: 3.05% flat rate for 2026 (phasing down from 3.23%). Counties add additional local income tax averaging 1.8%, making effective rates 4–6%.
Pennsylvania: 3.07% flat rate — the same since 2003. Pennsylvania also has local earned income taxes administered by municipalities, typically 1–3%.
Massachusetts: 5% flat rate on most income; 8.5% on short-term capital gains and certain dividends.
Utah: 4.65% flat rate with a nonrefundable personal exemption credit.
Progressive State Tax: Bracket States in 2026
Most states use a progressive bracket system modeled after the federal structure: as your income increases, higher portions are taxed at higher rates. The top brackets vary enormously — from 2.9% in North Dakota to 13.3% in California.
Key progressive states to know:
California (CA): The highest state income tax in the U.S. — 1% to 13.3% across 9 brackets. The 13.3% rate applies to income above $1 million. Even middle-income earners face 9.3%. This is the most significant state tax factor for high earners on the West Coast.
New York (NY): 4% to 10.9% state rate, plus New York City adds its own 3.078% to 3.876% tax. Combined NY+NYC rate can reach 14.8% for top earners.
New Jersey (NJ): 1.4% to 10.75%, with the top brackets applying above $1 million. Middle-income workers ($25K–$75K) pay 1.75–5.25%.
Minnesota (MN): 5.35% to 9.85% — one of the highest top rates in the Midwest.
Oregon (OR): 4.75% to 9.9% with a relatively low threshold for the top bracket ($125,001 for single filers in 2026).
State Withholding: How It Works on Your Paycheck
Your employer withholds state income tax from each paycheck based on the allowances or elections you declare on your state's withholding form (typically a state W-4 equivalent). Most states require employees to submit a state-specific form; many states also accept the federal W-4 for withholding purposes.
The withholding amount depends on: 1. Your gross pay per period 2. Your filing status (single, married, head of household) 3. Allowances or additional withholding claimed 4. Your state's withholding tables (updated annually)
States update their withholding tables when brackets or rates change. If you moved states mid-year, worked in multiple states, or changed jobs, you may need to reconcile withholding on your state tax return.
States with locality taxes (such as Indiana, Michigan, Pennsylvania, Ohio, and Kentucky) require additional local withholding on top of state withholding. Your employer handles this automatically based on your work and home address.
State Tax Reciprocity Agreements
Many neighboring states have reciprocity agreements — meaning if you live in State A and work in State B, you only pay income tax to State A (your home state). This simplifies filing for cross-border commuters.
Common reciprocity agreements include: - New Jersey ↔ Pennsylvania - Virginia ↔ Maryland, DC, West Virginia, Kentucky, Pennsylvania - Wisconsin ↔ Illinois, Indiana, Kentucky, Michigan - Indiana ↔ Kentucky, Michigan, Ohio, Pennsylvania, Wisconsin
Without a reciprocity agreement, you typically owe taxes to both states (your work state and your home state), though your home state usually credits the tax paid to the work state to prevent double taxation.
If your employer doesn't offer reciprocal withholding, you may need to pay estimated taxes to your home state quarterly to avoid underpayment penalties.
