"depreciation allowable at 100% business use" what does this mean?

how do I know what regular tax is and what amount

[Anita01 · Accepted solution]

Depreciation is taken on assets used for a business purpose based on how much of the total use of the asset was for business.  This is showing the depreciation received if you used the asset 100% for your business.  For example, if you use a cell phone 20% for business and 80% for personal use, you can only depreciate 20% of the cost of the phone, or the monthly expense.
