Best Practice for loading assets from an acquisition

We acquired a company on 3/17/2015. We are now trying to load the assets associated with the acquisition. For our CORP book, the cost is a revalued amount which is depreciated over a set number of months from the date of acquisition. This is working fine. For our tax books, we need the cost to be the original amount of the asset, but we only want to report the remaining depreciation amount.

For example: Original Asset purchased for $5000 on 5/15/2014.

At the date of acquisition, the CORP cost was $3916.68 which will be depreciated over the next 24 months straight line.

For Tax, the cost of the asset is $5000 which should be depreciated over 5 years using the Declining Balance with SL method.
