Calculation of total itemized deductions before phase-out: $0 medical ($12,000 - $328,000 10%-of-AGI) + home mortgage interest $16,000 + state and local income taxes $8,900 + real estate taxes $1,600 + charitable contributions $2,200 + investment interest expense $1,700 = $30,400.
Calculation of Itemized deductions subject to the overall limitation are as below:
State and local income taxes $8,900 + real estate taxes $1,600 + home mortgage interest $16,000 + charitable contributions $2,200 = $28,700
Thus, Pedro must reduce the amount by the smaller of the below:
In 2018, 3 percent of the amount by which AGI exceeds $313,800 ($261,500 if single).
-- 3% x ($328,000 AGI - $261,500) = $1,995
-- 80 percent of itemized deductions that are affected by the limit ($28,700 x 80%) $22,960
Therefore, the amount of the reduction is $1995. Pedro has $28,405 deductible itemized deductions ($30,400 - $1,995)
