My son is 17 and filing taxes. He received as I due to my disability. Do u include the 1099 on his taxes?

Yes, if he is filing a return he should include the SSA-1099 information.  It is not likely to be taxable unless he has substantial additional income (more than $25,000 for an individual or $32,000 for married filers).  

@jp5277

and you would only include HIS 1099 - not yours - on his tax return. (I took it that both of you are receiving a 1099)
