I inherited 14 storage units from my mom 2 years ago when she passed. She owned a small craft business and the majority of the items in these storage units was inventory and parts to create inventory. I opened a small thrift store to try an sell these items. I did that in 2019. I had to close in February 2020 so I decided to just donate much of the inventory and other items I had left in the store and storage units. It has been slow going and I have cleared out and donated items from a number of these units. I have about 25 donation receipts for 2020 that reflect large truck loads of boxes and crates of items all the way to car load's of boxes and crates. Most of the items are in new condition. I made general lists of what was in each container and some photos but there is so much of it! I donated one entire storage unit to The Salvation Army where a truck came and collected the items. I have no Idea how to put a value on this stuff as it was a 10x20 unit full to nearly the ceiling. I took photos of the unit beforehand, but I didn't make a list of each item as there were hundreds of items in there. I don't want to get into trouble with the IRS for claiming too much and I don't want to claim too little - I am still paying the storage unit fees each month for each unit. Then there are the other 24 receipts that have the number of boxes or bags I donated listed. All of the units are 10x20's and loaded! What can I legally do? Is there percentage I can use to calculate FMV? I didn't get any appraisals.
