This year, as usual, I filled out paper forms for my income tax. Just for curiosity I looked at the Free File software via the IRS site. I noticed that many of the choices were restricted to states of residence, income, and age.
Maximum income I understand -- let those people pay. But why, minimum income limits? Place of residence I understand, because sales tax deductions might be set up only of some states; foreign addresses I understand as the necessary forms for foreign taxes might not be there.
But why age limits?
