- If book taxes are greater than cash taxes
- Means you paid less in cash, so you create DTL
- If book taxes are smaller than cash taxes
- Means you paid more in cash, so you create DTA
- The difference between the book and cash tax amount dictates the DTA/DTL running balance
(Accelerated depreciation is an example that creates DTL, the depreciation is accelerated on the cash tax statements, which means you pay less cash tax - which creates a DTL).
