Final answer:
To calculate Rollin Ltd.'s maximum CCA deduction, the government grant is subtracted from the building cost, and the accelerated CCA rate is applied to find the first-year deduction of $456300.
Step-by-step explanation:
The maximum amount of Capital Cost Allowance (CCA) that Rollin Ltd. can deduct for the building for the fiscal year ending December 31, 2019, can be calculated by applying the accelerated investment incentive which allows a higher first-year CCA claim. First, we must subtract the government assistance received from the cost of the building. The initial cost is $6400000, of which $540000 is for the land, leaving $5860000 for the building. Then, deduct the government grant: $5860000 - $790000 = $5070000. Under the accelerated investment incentive, Rollin Ltd. can claim up to 1.5 times the normal CCA rate in the first year on the undepreciated capital cost. The normal CCA rate for class 1 is 6%, so 1.5 x 6% = 9% is the rate for the first year. Therefore, the maximum CCA for 2019 is 9% of $5070000, which is $456300.
