Exemptions ($3,650 × 4) ........ (14,600)

a. Assuming that Norman and Vanessa’s 2011 adjusted gross income will increase at the 1.5% rate of inflation and that the standard deduction and exemption amounts do not change, calculate their 2011 taxable income. Calculate the tax liability on this income using the 2010 tax rate schedules (Appendix B).
b. Calculate Norman and Vanessa’s projected 2011 taxable income and tax liability, assuming that their adjusted gross income will increase by 1.5% and that all other inflation adjustments are made. Compare these calculations with those in part a, and explain how the inflation adjustments preserve Norman and Vanessa’s aftertax income.
