You will not be using the fully depreciated assets for your tax return again.
Not always true. When you sell or otherwise dispose of the asset, all that depreciation has to be accounted for. For example, with a fully depreciated rental asset, when you sell the asset you are required to recapture and pay taxes on all depreciation taken, in the year you sell it.
Whereas in a case where the asset was destroyed or thrown away as an example, you would report it as such and the year you report it, would be the last year you'd need that asset to show on the 4562.
