In January 2019, Don and Steve each invested $100,000 cash to form a corporation to conduct business as a retail golf equipment store. On January 5, they paid Bill, an attorney, to draft the corporate charter, file the necessary forms with the state, and write the bylaws. They leased a store building and began to acquire inventory, furniture, display equipment, and office equipment in February. They hired a sales staff and clerical personnel in March and conducted training sessions during the month. They had a successful opening on April 1, and sales increased steadily throughout the summer. The weather turned cold in October, and all local golf courses closed by October 15, which resulted in a drastic decline in sales. Don and Steve expect business to be very good during the Christmas season and then to taper off significantly from January 1 through the end of February. The corporation accrued bonuses to Don and Steve on December 31, payable on April 15 of the following year. The corporation made timely estimated tax payments throughout the year. The corporation hired a bookkeeper in February, but he does not know much about taxation. Don and Steve have retained you as a tax consultant and have asked you to identify the tax issues they should consider.
