Hi TaxGuy Bill,

Thank you so much for you quick response.  I am very happy to have your affirmative support of this method for reporting the missed depreciation.  All asset items were fully depreciated prior to my husband's death on 12-15-2020, except for one item that had a remaining book balance of $657.00 at that time, and this item continued to depreciate fully through year 2023.  This item came to me from "joint tenancy with right of survivorship and not as tenants in common" in Kansas.  As I understand it, 50% of that depreciation would have been correct, so $328.50 of that would have been over-depreciated using the wrong basis of cost less accumulated depreciation rather than the FMV basis as it should have been done.  I was planning to correct for this by simply making a reduction to my total prior years' depreciation for that amount, then placing the difference into Form 3115.  I thought this adjustment would correct adequately and accurately for this one item.  What do you think about this?

Just for verification with you, there were two items that came to me under joint tenancy, and all the rest of the items were simply "willed" into my ownership as inheritance.  For the joint tenancy items, I used 50% of FMV at time of death, plus 50% of initial cost value less accumulated depreciation, as my new basis.  Then, for the "willed" items, I used 100% of the FMV at date of death as my new basis.  Please acknowledge if you believe I have done this correctly, or let me know if I need to make any changes.

Thanks so much for your expertise!
