There is an option to run tax depreciation but to run this an FA journal has to be posted for each asset you wish tax depreciation to be calculated for. The Tax depreciation book code must also be specified on each asset.

The FA card should contain a field such as Tax disallowable % (and/or value). If this field is blank the system should use the acquisition cost if say 10% is in the field it should take the acquisition cost less 10% as the tax depreciation value.

If the Company and Tax depreciation books have been set up when you run Calculate depreciation and select the Depreciation book (either Company or Tax) the system should know which values to use negating the need to have to enter 2 depreciation books on the individual asset records.

This will save organisations time and money on having to liaise with Auditors and rely on Auditors producing the calculations.
