Retirement Subtractions. Illinois bases its state income tax on your federal adjusted gross income, which includes federally taxable retirement income. When you fill out your state income tax return, you subtract distributions from pensions and other retirement plans from your federal AGI.
For example, in the U.S in the late 19th century it was estimated that the average work week was over 60 hours per week. Today the average hours worked in the U.S is around 33, with the average man employed full-time for 8.4 hours per work day, and the average woman employed full-time for 7.7 hours per work day.
How much work does the average American do each year compared to workers elsewhere in the world? The economics website FRED just added a bunch of new economic data which makes this question very easy to examine. As you can see, the average full-time American employee works right around 1,700 hours per year.
