I was just skimming through most of this thread, so I might have missed something here. But....did the OP say something about an IRA?
If so, be meticulous in how you handle the transfer. The IRS is very rigid about inheriting IRAs.
- Assume your mom was taking withdrawals, so as beneficiary you must continue those, but based on your age. Any tax adviser can help you with this, or just research it on the IRS website.
- Most important, be CERTAIN you instruct your designated financial institution to set up an Inherited IRA account to receive your mother's retirement account. Do not, under any circumstances, mix her assets into your own retirement account, nor take the assets in a check made out to you (with the laudable intention of opening a new IRA personally).
Inherited retirement accounts must always be kept separate, and the "cleanest" way to do it is to have the assets transferred directly between financial institutions, never personally touching it. The IRS just loves those unknowing inheritors who aren't aware of the rules so the Feds can claim the whole thing as income tax-liable, LOL.
My condolences to you on your mom's death. Dementia is so hard on families. You're right, it's something of a relief when you don't have to face an ever-worsening situation. It's a cruel disease and too often heart-breaking.
