US Paycheck Calculators by State (2026)

1How State Income Taxes Impact Your Paycheck in 2026

When an employee earns wage income in the United States, their gross pay is subject to three distinct layers of taxation: Federal Income Tax administered by the IRS, Federal Insurance Contributions Act (FICA) taxes for Social Security and Medicare, and State/Local withholding taxes. While federal income tax brackets and FICA rates (6.2% Social Security up to $184,500 wage base, 1.45% Medicare plus 0.9% Additional Medicare above threshold limits) are uniform across all 50 states, state-level withholdings vary dramatically depending on geographic jurisdiction.

State income taxes directly reduce an employee's disposable net income per pay period. In 2026, individual state tax burdens range from 0% in states like Texas, Florida, and Nevada to top marginal tax rates exceeding 10% in states like California, Hawaii, New York, New Jersey, and the District of Columbia. For a remote worker or relocating employee earning an $85,000 annual salary, moving from a high-tax state to a no-tax state can result in an instant take-home pay increase of $3,500 to $5,000+ per year without requiring a raise.

2Flat vs. Progressive vs. Zero-Tax States Explained

US state tax systems are categorized into three primary structural models across the 51 jurisdictions:

• Zero State Income Tax (9 States): States such as Texas, Florida, Nevada, Washington, Tennessee, South Dakota, Wyoming, Alaska, and New Hampshire (where wages are untaxed) charge 0% state income tax on personal wage income. These states fund state budgets primarily through higher sales taxes, property taxes, tourism taxes, or natural resource severance revenues.
• Flat Tax States (16 States): States including Illinois (4.95%), Indiana (3.05%), North Carolina (4.5%), Georgia (5.39%), Michigan (4.25%), Arizona (2.5%), Iowa (3.8%), Colorado (4.4%), and Utah (4.55%) levy a single percentage rate on all taxable wage income regardless of total earnings. Flat tax models offer simplicity and predictability for payroll processing.
• Progressive Tax States (26 States + DC): States such as California (1.0% to 12.3%), New York (4.0% to 10.9%), New Jersey (1.4% to 10.75%), Minnesota (5.35% to 9.85%), and Oregon (4.75% to 9.9%) employ graduated tax brackets. Lower tiers of taxable income are assessed at lower rates, while higher tiers face higher marginal rates.

3State Disability Insurance (SDI) and Paid Family Leave (PFL) Deductions

In addition to standard state income tax withholding, several state governments mandate separate employee-funded payroll programs for short-term disability insurance and paid family leave. These deductions are listed as itemized payroll line items on employee pay stubs:

• California SDI: Mandatory 1.1% State Disability Insurance tax withheld on 100% of gross wages.
• Massachusetts PFML: Mandatory employee payroll contribution (0.46% combined split for medical and family leave).
• New York SDI & PFL: Mandatory Disability Benefits Law (DBL) plus Paid Family Leave (PFL) contributions.
• Washington PFML & WA Cares: Employee-funded payroll premiums for family leave (0.58%) and WA Cares long-term care fund (0.58%).
• Oregon & Colorado Paid Leave: Paid Leave Oregon (0.6%) and Colorado FAMLI (0.45%) employee payroll deductions.

4Reciprocal State Tax Agreements for Remote & Multi-State Workers

With the rapid growth of remote work and interstate commuting, many workers live in one state and work in another. Generally, employees owe state income tax to the state where services are physically performed, as well as their state of legal residence. However, to prevent double taxation on workers, dozens of neighboring states have established formal Reciprocal Tax Agreements.

Under a reciprocal agreement (such as between Pennsylvania and New Jersey, or Maryland, Virginia, and D.C.), an employee working in a neighboring state can submit a non-residence certificate to their employer. This authorizes the employer to withhold state income tax strictly for the worker's home state of residence rather than the state where the office is located. For states without reciprocal agreements, taxpayers can claim a resident state tax credit for income taxes paid to another state on their annual tax returns.
