My Taxes

State Income Tax Overview: Flat, Graduated, and No-Tax States

Understand how state income taxes differ across the U.S.—flat rates, graduated brackets, and states with no wage income tax—and how My Taxes estimates them.

States take different approaches

Federal income tax is only part of many households’ tax picture. States may impose their own income tax with a flat rate on all taxable income, graduated brackets similar to the federal system, or no broad-based wage income tax at all.

My Taxes includes state income tax rate data for supported years so you can see brackets for the state you select alongside federal results.

No wage income tax is not “no tax”

States commonly described as having no income tax generally do not tax wage income the way federal Form 1040 does. Residents may still pay sales tax, property tax, business taxes, or limited taxes on specific income types. Always check your state’s department of revenue for the full picture.

Flat vs. graduated structures

A flat tax applies one rate above any exempt amount the state defines. Graduated systems use multiple rates and thresholds, sometimes with different widths for single and joint filers. A few states have been moving from many brackets toward flatter designs over recent years.

Because structures change, pick the correct tax year in My Taxes when you compare states or plan a move. Mid-year legislation can also alter rates after a calendar year begins.

Local taxes and special cases

Some cities and counties add local income or wage taxes that are not included in the My Taxes state tables. Special rules for part-year residents, remote work, and reciprocal agreements can also change where income is taxed.

Use the calculator for a clear first look at state bracket math, then confirm details with official state guidance when the amounts matter for filing or relocation decisions.
