Client’s books weren’t necessarily the cleanest the past two years (2018 is clean as a whistle). New bookkeeper uncovers a few assets (less than $25K in total cost) that were omitted from the balance sheet, and thus the 1120S returns we filed.
I know this isn’t a rare circumstance, but I’ve never run across it. Is a 3115 required to recoup the missed depreciation or can we file a 1120-X? And, since the 2018 was extended, but filed in April, can I amend it with a 3115?
Thanks for any advice.
