I just got an SSA-1099. It says it is a Social Security Benefit Statement. On the back it says info is for my records, Do not attach to your tax returns. I am mailing my federal state and city tax returns. I don't understand why I am not suppose to include copies of this in all my tax returns as it IS income I am reporting. And also it only shows 1 copy! Not 4 like a W2 does (one to keep then one for fed, state and city tax returns) Tried asking about this as a followup question to another I posted but I was not sure about response I got. I did have federal taxes withheld from the pay listed in box 6.
