I am reviewing my 96 year old mom’s corporate and personal taxes because her accountant has made such egregious errors. She owns a warehouse she rents out. She owns another building but it is used for personal not building. After a 10 yr tenant damnnear destroyed the warehouse, we had major repairs and a couple new depreciable improvements. The accountant that took over after my dad died in 2020 said she could only write off $2500.00. I am discovering that he also made other ridiculous errors. Laughable. I redid her 2023 corporate taxes and all of his mistakes actually came to a wash. That was before we evicted a bad tenant and were left with major structural damage to repair. So in 2024, he has a whole list of depreciation items of which some are the urgent repairs not to be depreciated, some items don’t exist in the building anymore and haven’t for over 25 years 🤦🏼‍♀️, and he’s incorrectly depreciating small items like an air conditioner at 39 years. I assume I need an 1120-X for 2024 before I can do her 2025 1120and 1040Sr. Do I also need a 3115?
