Here we detail about the two heads for treatments of asset disposal account.
(A) When Depreciation is Charged to the Asset Account:
In this case depreciation is charged to asset account and in the balance sheet, the asset is shown at its written down value (i.e., less of depreciation). When an asset is sold, the written down value of the asset is transferred to the debit side of a separate account called ‘Asset Disposal A/c’.
Depreciation for the year (till the date of sale) on the respective asset and the sale proceeds from the sale of the concerned asset are transferred to the credit side of this account. The balance representing the profit or loss on the sale of asset should either be debited or credited in this account.
The following journal entries have to be passed:

(B) When Depreciation is Accumulated in a Separate Account:
In this case depreciation is charged to a separate account known as ‘Provision for Depreciation Account’ or ‘Accumulated Depreciation Account’ and in the balance sheet the asset is shown at its original cost. When an asset is sold, the original cost of the concerned asset is transferred to the debit side of a separate account called ‘Asset Disposal A/c’.
Accumulated depreciation (till the date of sale) on the respective asset and the sale proceeds from the disposal of the concerned asset are transferred to the credit side of this account. The balance represents either profit or loss on the sale of asset and should be debited or credited in this account.
