Retirees who are concerned about taxes can find some solace in the North Star State. The same amount of taxes apply to Social Security benefits as they do on your federal return, however, taxpayers who receive taxable Social Security benefits may be eligible to deduct several of their payments if their earnings are below a certain threshold. 

Additionally, some seniors qualify for a special income tax deduction. But pensions, aside from those received from the military, are taxable. IRA and 401(k) plan distributions are taxed as well.
