A corporation generates a $72,000 NOL in 20 times 6. The corporations modified taxable income for the following years are as follows. 20X1 $19,000 20X2 $25,000 20X3 $3,000 20X4 $10,000 20X5 $12,000 20X7 $22,000 20X8 $21,000 Assume that the marginal tax rate of the corporation is 15 percent from 20x1-20x5 and 34 percent from 20x7-20x9. Compute the total tax savings generated from the NOL assuming (a) that the corporation does not forego the carry back period, and (b) the corporation elects to forego the carry back period. For purposes of this calculation, assume that any remaining NOL carryover is utilized in 20x9
