How do I claim and report medical and dental expenses?

If you are planning to deduct your medical and dental expenses, you have to itemize your deductions and use Form 1040 (so you cannot use Form 1040A or Form 1040EZ). Once you have figured out your medical and dental expenses, you can use Schedule A to calculate what percentage of those expenses can be deducted (remember, only those expenses above the 7.5% floor can be deducted).
