Q. Since my only income is Social Security disability I don’t pay taxes so I would only get a refundable portion of $1000 on my taxes correct?
A. Yes.
Q. But if my son claim is independent then I don’t get this credit?
A. That's correct.
Q. And you mentioned he would not get the refundable part back but I don’t understand why just because independent.
A. That's just a rule. Congress created the credit for parents, not young students. Reference: Line 7 instructions for form 8863. https://www.irs.gov/instructions/i8863
Q. You said something about increasing the income by $4000 but isn’t the credit only $2500?
A. The $4000 additional income is taxed at 12% (maybe only 10%). $4000 x 0.12 = $480. That's what you compare the $2500 credit to.
The rest of your post is about health insurance and state benefits. This forum is only about income tax and TurboTax software. I don't think anyone here is going to be able help you with those questions.
