My son is 18, in high school, my dependent and receiving SSI payments. Will I have to show these earrings on my tax return?

NO

No.   You do not enter your child's SSI on your own tax return.  And....do you really mean SSI or do you mean Social Security?  People mix up those terms a lot, and when we are trying to answer a tax question it is important to understand which one you really mean.

WHAT IS THE DIFFERENCE BETWEEN SOCIAL SECURITY BENEFITS AND SSI?

If your son is receiving Social Security (survivor benefit?)  then he does not file a tax return for that.  But if he gets a job and has any other income, the SSA1099 will go on his tax return if he files a tax return of his own at some future time.

I’ve always been told SSI. He is disabled.

Do not put your child's SSI on your own tax return.  SSI is not taxable.

Does he get a SSA-1099 form for it?   Either way you don't include his income on your return.  He only has to file a return if  he has other income or to get back any withholding taken out.
