Your Guide to State Income Tax Rates

Location is everything if you want to save a few income tax dollars. Overall, state tax rates range from 0% to more than 13% as of 2021.

California, Hawaii, Oregon, Minnesota, New York, and New Jersey have some of the highest state income tax rates in the country and eight states have no tax on earned income at all. Another ten have a flat tax rate—everyone pays the same percentage regardless of how much they earn.

2021 Top Income Tax Rates By State

California tops the list with the highest tax rates in the country—its highest tax rate is 13.30%, a full 2.3% more than Hawaii, the runner-up for the highest tax rate with 11.00%. California applies its highest tax rate to those who earn more than $1 million. 

Rounding out the top-10 states with the highest tax rates are:

• New York: 10.90%
• New Jersey: 10.75%
• Oregon: 9.90%
• Minnesota: 9.85%
• District of Columbia: 8.95%
• Vermont: 8.75%
• Iowa: 8.53%
• Wisconsin: 7.65%

States Without Income Tax

On the flip side, Alaska, Florida, Nevada, South Dakota, Texas, Washington, Wyoming, and Tennessee 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 5%.

Some states generate revenue in other ways, though:

• 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.
• 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 ten states that have flat tax rates as of 2021. The flat-tax states and their rates, from highest to lowest, are:

• North Carolina: 5.25%
• Massachusetts: 5.00%
• Kentucky: 5.00%
• New Hampshire: 5.00% (only on dividend and interest income)
• 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 the District of Columbia 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.
