(The Center Square) – Illinois has the highest tax rates in the country, according to a new analysis.

The personal finance website WalletHub has released its yearly report on the “States with the Highest and Lowest Tax Rates.” 

Illinois highlighted in WalletHub's Best and Worst States to be a Taxpayer report - WalletHub.org

“What we did is we compared all 50 states and the District of Columbia across four different types of taxation, and those are real estate tax, vehicle property tax, income tax, and sales excise tax,” said researcher Chip Lupo.

Overall, Illinois placed last in the country for taxation, coming in at 51st for overall effective state and local tax rate, 50th for real estate taxes, and 47th for income taxes. Illinois also pays the second highest gas taxes in the country..

The study found that the percentage difference between Illinois taxes and the U.S. average is an astounding 51.8%. The next closest is New York at 34.9%. At the other end of the spectrum is Alaska at -37.9%.

According to the study, behind Illinois, the highest taxed states are New York and Connecticut. The least taxed states are Alaska, Delaware and Wyoming.

The study found that Red states with Republican majorities impose lower taxes than Blue states with Democratic majorities. The average rank for Red states is 24.3, while the average rank for Blue states is 28.5.

WalletHub also conducted a tax survey, asking 200 taxpayers various questions about filing taxes.

“Seven in 10 Americans right now are more worried about inflation than taxes, which I thought was a pretty high number,” said Lupo.

The survey also found that nearly 1 in 3 people would rather do jury duty than their taxes.
