Black Holdings Ltd. is a Canadian-controlled private corporation that sells farm supplies. It owns 70 percent of the outstanding shares of Blue Inc. On November 1, 2021, Blue Inc. declared and paid a non-eligible dividend of $21,000, of which Black Holdings Ltd. received $14,700 (70 percent). As a result of paying the dividend, Blue Inc. received a dividend refund in the amount of $8,050.

Other income that was reported by Black Holdings consisted of the following amounts:

Capital Gain $9,200

Eligible Dividends From Imperial Oil Common Shares 500

Interest 450

The capital gain was on the sale of land that was formerly used as a storage area for inventories. Improved inventory control procedures have eliminated the need for this land.

The interest is on deposits of temporary cash balances set aside for the purchase of inventories.

On January 1, 2021, Black had a Non-Eligible RDTOH balance of $4,950. There was no balance in either the Eligible RDTOH or the GRIP account on this date.

At the end of 2020, the Company's Refundable Dividend Tax On Hand balance was $8,950. The 2020 dividend refund was $4,000. There was no December 31, 2020 balance in the corporation's GRIP.

The Company's Taxable Income for the year ending December 31, 2021, was $44,000. No foreign income was included in this total. Assume the Part I Tax Payable for the year ending December 31, 2021, was correctly calculated as $9,250.

Because of its association with Blue Inc., its share of the annual business limit on income eligible for the small business deduction is $10,000. As Black's active business income is greater than $10,000, the amount of income that is eligible for small business deduction is equal to $10,000.

Black Holdings paid taxable dividends of $10,000 during 2021. The corporation's policy is to designate dividends as eligible only to the extent that a refund is available on their payment.

For 2020, Black and Blue had a combined ADJUSTED Aggregate Investment Income of $32,485. Their Taxable Capital Employed In Canada totaled $6,426,000 for 2020.
