Learn Your State's Tax Rate Before You File State Taxes

Thirty three states use a progressive (graduated) tax system that resembles the federal government’s income tax structure. The number of tax brackets in these states tends to be lower than the number of federal brackets and the actual tax rates. In some states such as Kansas they maintain just two tax brackets, in others such as California and Missouri they have up to 10 brackets.

California has one of the highest state tax rates in the country. The top tax rate is 12.3%. It also imposes an additional 1% tax on incomes over one million dollars.

Of states with an income tax (seven states do not collect an income tax), North Dakota has one of the lowest tax rates. The top tax rate in this state is just 2.9%.

Illinois (3.75%)
Indiana (3.3%)
Massachusetts (5.10%)
Michigan (4.25%)

The Five Worst States for Taxes

According to the US Bureau of Labor Statistics, the average US household pays more than $5,700 in federal income taxes per year. While virtually all Americans are assessed the same federal income tax rates regardless of where they live, there are substantial variations in how much they are taxed by state and local governments.

The five states with the highest top tax rate are California, Hawaii, Oregon, Minnesota, and Iowa. Besides the rates themselves there are also variations in the income tax brackets used by many states.

While 33 states (34 if you include the District of Columbia) assess a graduated income tax based on income brackets, eight states levy a flat percentage regardless of salary. Tennessee and New Hampshire also use a flat rate but only on dividends and interest. They do not tax W-2 wages. Seven states—Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming—do not have a state income tax at all.

States Compared by "Effective Tax Rates"

To accurately calculate the "effective tax rate," property taxes, school taxes, sales taxes and levies on such expenses as vehicle registration must be included. Using this, taxpayers in the Northeast and Midwest generally have the highest "effective tax rate," while those living in the South and parts of the West have the lowest. According to the US Tax Foundation and the US Bureau of Labor, taxpayers in these five states shoulder the biggest tax burdens:

  1. Illinois: Residents pay an "effective tax rate" of 14.54 percent—or 14.5 cents per dollar of income.
  2. Nebraska: 13.8 percent.
  3. Wisconsin: 13.6 percent.
  4. New York: 13.58 percent.
  5. Rhode Island: 13.57 percent.

By the same standards, the five "best" states for taxpayers are Wyoming, Alaska, Nevada Florida and South Dakota. Not surprising, none of these have a state income tax.
