The Bookbinder Company has made $150,000 before taxes during each of the past 15 years, and it expects to make $150,000 a year before taxes in the future. However, in 2015 the firm incurred a loss of $650,000. The firm will claim a loss carryback at the time it files its 2015 income tax return, and it will receive a cheque from the CRA. Show how it calculates this loss carryback, and then indicate the firm's tax liability for each of the next 5 years. Assume a 40% tax rate on all income to ease the calculations.
