Following a suggestion in an answer to my previous question, I'm considering claiming, on my tax returns, some losses due to theft.
My co-owner hasn't paid me my share of profits on our co-owned rental properties, ever, going back more than 30 years. I've been paying taxes on my share. He always said he would pay me back eventually, but supporting his family was always his #1 objective.
Now he's dead, and the value of his estate is a small fraction of his debt.
My estimate - he hasn't given me any numbers since 2010, so I'm not sure of the profits since then - is that I'm owed around $90K. He also didn't pay $24K in back property taxes, which I'll have to pay by myself.
My understanding is that loss from theft must be claimed in the year the theft happened. Since almost all these occurrences are more than three years ago, does that mean I'll never get a tax refund from these losses?
