Trevor is a single individual who is a cash-method, calendar-year taxpayer. For each of the next two years (year 1 and year 2), Trevor expects to report AGI of $80,000, contribute $8,000 to charity, and pay $2,800 in state income taxes.
a. Estimate Trevor’s taxable income for year 1 and year 2 using the 2018 amounts for the standard deduction for both years.
b. Now assume that Trevor combines his anticipated charitable contributions for the next two years and makes the combined contribution in December of year 1. Estimate Trevor’s taxable income for each of the next two years using the 2018 amounts for the standard deduction. Reconcile the total taxable income to your solution to part (a). 

c. Trevor plans to purchase a residence  next year, and he estimates that additional property taxes and residential interest will cost $2,000 and $10,000, respectively, each year. Estimate Trevor’s taxable income for each of the next two years (year 1 and year 2) using the 2018 amounts for the standard deduction and also assuming Trevor makes the charitable contribution of $8,000 and state tax payments of $2,800 in each year.
d. Assume that Trevor makes the charitable contribution for year 2 and pays the real estate taxes for year 2 in December of year 1. Estimate Trevor’s taxable income for year 1 and year 2 using the 2018 amounts for the standard deduction. Reconcile the total taxable income to your solution to part (c).
e. Explain the conditions in which the bunching strategy in part (d) will generate tax savings for Trevor.
