Final answer:
Maple Co.'s small business deduction for the year is $43,200.
Step-by-step explanation:
To calculate Maple Co.'s small business deduction, we need to determine the Corporation's taxable income for the year. The small business deduction is equal to the lesser of $500,000 or the Corporation's taxable income multiplied by the federal small business deduction rate.
In this case, Maple Co.'s taxable income is the sum of its active business income ($450,000) and capital gains ($30,000), which totals $480,000. Since $480,000 is less than $500,000, we can use it for the calculation.
The federal small business deduction rate for this year is 9%. Therefore, Maple Co.'s small business deduction for the year is $480,000 multiplied by 9%, which equals $43,200.
