California has the highest income tax rates in the country—its top rate is 12.3%. Still, it also imposes an extra tax on people with an income of
$1 million or more, bringing the total tax rate to 13.3%.
2 This "millionaire's tax" form is also enacted in New Jersey and New York. 34 Other states have a high tax rate, although not all have the same number of income bands that lead up to it.
Hawaii, for example, has an 11 percent top tax rate and 12 income groups. In contrast, Iowa has an 8,53 percent top tax rate and nine income brackets. Washington, D.C., of course, is not a state, but it does have its income tax rate.
States without a personal income tax
On the other hand, Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington state, and Wyoming have no income tax. New Hampshire is in the middle of the pack. It doesn't tax earned income but collects a flat 5% tax on interest and dividends.
Some states earn revenue differently since they do not collect income tax. Tennessee's combined state and local sales tax rate is one of the highest in the country. Although your paycheck will be protected, you will be charged at the cash register. Property taxes in New Hampshire and Texas are expensive compared to home values. In 2021, Pennsylvania imposed the highest gasoline tax.
States that have a flat tax rate
Many residents in the states that impose income taxes get a discount because the highest rates don't apply until higher income levels. However, this is not the case in the ten states with flat tax rates as of 2021. The table below shows the flat-tax states and their rates, from highest to lowest.

A State-by-State Analysis of Income Tax Rates in Comparison
The remaining states and Washington, D.C. levy a "progressive" income tax based on tax bands on all income. The bigger your income, the more significant the proportion of your earnings you'll pay in income tax. California's top rate, for example, is 13.3 percent, but you'll only pay it if your income exceeds $1 million.

Commonly Asked Questions (FAQs)
What is the purpose of state income tax revenue?
State budgets determine how tax revenue is used. The budgeting process varies per state, but it generally follows the federal procedure of reaching a spending agreement between the legislative and executive branches.
Where do you pay your income tax if you work out of state?
It's a given that you'll have to submit income taxes in the state where you live. Workers in several states can only file taxes in the state where they live, regardless of where they work. If your job requires you to travel across state borders, you may or may not be required to file taxes in another state. See a tax specialist to learn how state laws apply to your situation.
