2021 Top Income Tax Rates by State

Below, you'll find the top 10 states with the highest income tax rates.

State  Top Income Tax Rate 
California  13.3% 
Hawaii 11%
New York  10.9% 
New Jersey  10.75% 
Oregon  9.9% 
Minnesota  9.85% 
Washington, D.C.  8.95% 
Vermont  8.75% 
Iowa  8.53% 
Wisconsin 7.65% 

California tops the list with the highest income tax rates in the country—its highest tax rate is 12.3%, but it also implements an additional tax on those with income of $1 million or more, which makes its highest actual tax rate 13.3%. New Jersey and New York also implement this type of "millionaire's tax." Other states have a top tax rate, but not all states have the same number of income brackets leading up to the top rate. For example, Hawaii has a top tax rate of 11% and 12 income brackets, while Iowa has a top tax rate of 8,53% and nine income brackets. And of course, Washington, D.C. is not a state, but it has its own income tax rate.

States Without Income Tax

On the flip side, Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington state, and Wyoming don’t impose an income tax at all. New Hampshire falls into a gray area. It doesn't levy a tax on earned income, but it does tax interest and dividends at a flat 5%.

Since they don't collect income tax, some states generate revenue in other ways. Tennessee has one of the highest combined state and local sales tax rates in the country. Your paycheck might be safe, but you'll be dinged at the cash register. New Hampshire and Texas have high property taxes in relation to home values. And Pennsylvania charged the highest tax on gasoline in 2021.

States With Flat Tax Rates

Among the states that do have income taxes, many residents get a break because the highest rates don't kick in until upper-income levels. But this isn't the case in the 10 states that have flat tax rates as of 2021. The flat-tax states and their rates, from highest to lowest, can be seen in the table below.

State  2021 Flat Tax Rate 
North Carolina  5.25% 
Massachusetts  5% 
Kentucky  5% 
New Hampshire  5% (interest and dividend income only) 
Illinois  4.95% 
Utah  4.95% 
Colorado  4.55% 
Michigan  4.25% 
Indiana  3.23% 
Pennsylvania  3.07% 

A State-by-State Comparison of Income Tax Rates

The remaining states and Washington D.C. charge a "progressive" tax on all income, based on tax brackets. The more you earn, the higher the percentage you'll pay in income tax on your top dollars. For example, California's top rate is 13.3%, but you'll only pay this on income over $1 million.

Frequently Asked Questions (FAQs)

How is state income tax money used?

Tax revenue is used according to state budgets. The budgeting process differs by state, but in general, it mirrors the federal process of legislative and executive branches coming to a spending agreement.

Where do you pay income tax for out-of-state work?

You should always expect to file income taxes in the state where you live. If you cross state lines for your job, you may or may not have to file taxes in another state, too. Some states have agreements that allow workers to only file taxes where they live, regardless of where they work. Check with a tax professional to learn how state laws may apply to your situation.
