You make the call

Question: A new client owns rental property they purchased over 10 years ago. They are planning to sell it but have not previously claimed depreciation on the property. When we report the sale on Form 4797, the form requests the depreciation allowed or allowable since acquired. Do we calculate the depreciation they should have claimed in the past and include it on Form 4797 to report the sale, or do we report $0 depreciation since none was ever claimed?

Answer: In the year of sale, report on Form 4797 all depreciation that should have been claimed in the past plus any for the current tax year being filed. The key here is that you also need to complete Form 3115, Change in Accounting Method, to report the missed depreciation discovered at the time of sale. The Form 3115 results in a negative §481(a) adjustment for missed depreciation that is taken in the current tax year in which the rental is sold. Show the “§481(a) adjustment” on the other expense line of their Schedule E.
