@Sullivan–The pertinent part of the medical expense deduction for that question is that for taxable income medical expenses are only deductible over 7.5% of AGI for anyone OVER 65. Because he is 70, he deducted $3,750 from income ($15K – ($150K * .075)), but for AMT he can only deduct anything over the 10% floor of $15,000, which is $150K * 10%.. You have to add back the $3,750 deduction he took to arrive at taxable income to get his AMT amount. So the $35K I calculated earlier for the other items + $3,750 for a total of $38,750 is added back to taxable income to get to AMT.
If he had been under the age of 65, the 10% floor would have applied to both taxable income and AMT so you would have disregarded the item as an AMT adjustment.
