Social Security Disability+taxes to custodial parent
My daughters father was granted his SSD (not retirement or SSI but Disability) and stated that our daughter will receive a check for a monthly amount that is greater than his child support obligation (between $40 and $60 of a difference). He asks that I go to the Social Security office and fill out the paperwork because he is not the custodial parent so he was told he cannot file on her behalf. Supposedly the amount will be retro to 2.5 years ago when he first filed. He asks that I also go the Friend of the Court and ask for a reduction/adjustment/review because what SSD will pay is more than his child support. Okay, not thrilled with taking the time off work to do it, but OK. I don't expect him to pay child support in addition to the SSD payment, he will be receiving under $1000/mo and has to live. From my understanding, Michigan will not have him pay child support separetely from the SSD because the amount will be greater. He is under $500 I believe in child support back owed so not much to make a fuss about and not really a factor.
The problem is that he asks that when our daughters retro SSD check comes in (in my name on behalf of our daughter is my understanding how it will be addressed), to cash it and give him the money because he has to pay back his previous employers long term disability he received before receiving the SSD. Now that he has SSD he will need that money to pay it back or will not be able to survive. Ok, whatever, not a big deal. I can live without the 10-12K and support my daughter.
My question though is if I will be taxed on our daughters monthly and retro payments? My base pay is 65K a year. Do I claim the SSD or file taxes on behalf of my daughters SSD check(s)? Because this will make a big difference if that money is given to him or if it goes into my daughters college fund because I don't want to be penalized for receiving money I didn't actually receive and use. Thank you!
