It is considering selling a second capital asset before the end of 2021. This sale would generate a $21,000 capital gain that would allow the corporation to deduct its entire capital loss. Alternatively, it could carry its $20,000 net capital loss back to 2018 and 2019 and receive tax refund. Assume that the corporation's marginal tax rate is 15% in 2018 and 21% in 2019. Which course of action do you recommend and why? (Hint: Calculate the tax saving under the two scenarios and recommend accordingly)
