Hello, I have a question on Joint bank accounts and taxes. so here is the background: My Dad passed away 2 years ago and my mother has Lewy body dementia. when he died I took over all of the financials and my mother moved into an assisted living home. Now when my dad died we received a life insurance check for $180,000 that I put into my mothers name and into an investment account. My mom is now telling me she would like me to have a percentage of this money. If I were to use 50k to pay off my home from our joint checking account does some IRS guy come knocking at my door...?
