There are usually two cases in which you would write-off an asset from your accounting books. As I’m sure we have all experienced, hard drives crash and laptops and desktop computers become more useful as paperweights than office equipment. In this instance, the asset is donated or placed in the “circular file” for disposal with no resale market value. This is probably the most common scenario. To remove the asset from your accounting records, you would normally have to create an adjusting journal entry that removes the accumulated depreciation and the original acquisition cost. If the asset is fully depreciated, then the entry is fairly straightforward.
