8. Idaho

Total Returns: 663,291
Returns With Income Tax Liability: 407,579
Returns With No Income Tax Liability: 255,712
Nonpayers: 38.6%

Like Texas, Idaho lacks many of the attributes typical of a state with high numbers of nonpayers. However, it has the sixth-highest rate in the nation of tax returns claiming unemployment compensation. “The jobs picture in that state likely contributes to the nonpayers phenomenon,” Kasprak said.

An analysisfrom the Center on Budget and Policy Priorities, which states that a lowered unemployment rate would increase the number of people paying income tax, bears out this observation. As long as unemployment stays high, so will the number of people paying no income tax.
