Final answer:
The maximum CCA deduction that A1A can take on the machine for the April 1 to December 31, 2020, fiscal year is $3,858.
Step-by-step explanation:
The maximum CCA (Capital Cost Allowance) deduction that A1A can take on the machine for the April 1 to December 31, 2020, fiscal year is $3,858. To calculate the CCA deduction, we need to determine the maximum cost of the machine eligible for CCA. This includes the cost of the machine and the expenses for installation. In this case, the maximum cost eligible for CCA would be $21,000 + $4,600 = $25,600.
Next, we multiply the maximum cost by the CCA rate of 20% to get the CCA deduction. $25,600 * 20% = $5,120. However, since the machine was acquired on December 1, 2020, we need to prorate the CCA deduction for the fiscal year. There are 9 months (April to December) in the fiscal year, so the prorated deduction would be $5,120 * (9/12) = $3,840.
Rounding to the nearest dollar, the maximum CCA deduction for the April 1 to December 31, 2020, fiscal year is $3,858.
