Does anyone know?

It will go to next of kin. At least thats how it worked when my brother passed almost 7 years ago. We filed and my parents got his return.

I would imagine that it would go into the estate. So if you are the only one benefitting from the estate then I guess it would be yours eventually. If there are other beneficiaries, then it would be split up amongst everyone.

Sorry to hear about your mom, hopefully she had a will, or signed rights over to someone. Otherwise the state takes it, unless it is in writing, that someone is the beneficiary.

Thank you KFree....She didnt have a will, she had a notary sign a paper leaving me her house and car upon her death. I was her only child, does that make me her beneficiary?

yes if your the only child it would be that gets the money. the irs would be able to comfirm that with their records.
