First----let's clear up that there is a big difference between receiving Social Security benefits and "SSI"----we see people refer to "SSI" a lot when they really mean Social Security or Social Security Disability.
SSI is not reported on any sort of tax document at tax time and does not get entered on a tax return. SSI is not taxable.
Social Security benefits or Social Security Disability is reported on a 1099SSA at tax time and may get entered on a tax return.

All of that being said, if you start receiving Social Security benefits of any kind, at tax time you will get a SSA1099. If you are also receiving some other sort of disability benefits, those might be on a W-2 or on a 1099.
