text: i am grandmothers getting ssi and ss.i also get k. k for 2grandchildren. do i file income tzx return..? i want to know since i have been getting social security and also raise 2 grandchildren for whome i get kin kap.  do i file income tax and would i get any return.  i have not filed in years thinking i didn't have to because i was getting surviors benifits.  i have also raise two other grandchildren to the age of 18.  recently someone told me i should have filed but i have never filed in over 20years.  not even when i was raising my six sons without a father.  i would like to have some answers as to what is expected of me in this situation. ask your state representative's office.  we all pay them to answer these types of questions for us.  ;)
