A List of State Income Tax Rates

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

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

Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming do not impose an income tax. Tennessee and New Hampshire fall into a gray area. They don't levy a tax on earned income, but they do tax interest and dividends. These states can get you in other ways, however.

• 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 is known for its exorbitant property taxes, and Nevada and Texas have high property taxes, too.  
• Washington charges a significant tax on gasoline, and Florida is known for both high property taxes and a pretty significant sales tax.  
• Wyoming and Alaska are the kindest states, at least for resident taxpayers. They take in a lot of revenue from taxation of their natural resources. 

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 nine states that have flat tax rates. These jurisdictions don't care how much you earn.

Flat tax states include:

• Colorado
• Illinois
• Indiana
• Kentucky
• Massachusetts
• Michigan
• North Carolina 
• Pennsylvania
• Utah 

The remaining states and the District of Columbia charge a "progressive" tax on all income. The more you earn, the higher percentage you'll pay in income tax. For example, California's top rate is 13.3%, but you'll only pay this if you earn more than $1 million.
