how much do medical expenses have to be to deduct from taxes
On 2012 tax returns, the medical expenses deduction is available only for amounts that are greater than 7.5 percent of your adjusted gross income, or AGI. A taxpayer with a $40,000 AGI will need more than $3,000 in medical bills, meaning that total medical costs of $3,100 only will produce a $100 itemized medical deduction.
