Capital Cost Allowance, DIEP and AII on a utility vehicle

[stannord]

HI, 

We purchased (financed) a Utility Vehicle for self-employment business in 2025 for the amount of $25,366.64. 

How do I know if its eligible to the DIEP and AII as it makes a big difference in the return.

When I click Yes to DIEP the return the CCA claims the full amount of vehicle. 

If I click no to DIEP, it asks me about AII , If I click no then the CCA is  $4299.64.

If I click no to DIEP, Yes to the AII, then the CCA is $8599.29.

Thank you
