The IRS allows you to deduct unreimbursed expenses for qualifying medical expenses if they exceed 7.5% of your adjusted gross income or AGI. These expenses can come from: Preventative care Medical treatments Surgeries Dental and vision care Psychologist and psychiatrist visits Prescription medications Prescription appliances (glasses or contacts, false teeth, hearing aids, etc.) Travel expenses paid to receive this medical care (mileage, bus fare, and parking fees) How much you can deduct depends on your income and whether you itemize your deductions. For example, if your AGI is $50,000 and you itemize your deductions, you can deduct any unreimbursed medical expenses in excess of 7.5% of your AGI, or $3,750 (7.5% of $50,000). If you had $5,000 in unreimbursed qualifying expenses, you can deduct $1,250 ($5,000 – $3,750).
