Can I deduct medical co-pays for office visits, x-rays, and blood screenings?

[MargaretL]

Yes, you can deduct co-pays, xrays and screenings. The costs are your medical expenses:

1. Federal Taxes
2. Deductions and Credits
3. Scroll down to Medical, select Medical Expenses - please follow the prompts

Those are all valid medical expenses, but they may not provide a tax benefit. Only the amount of such deductions that are more than 10% of your adjusted gross income (if you are under 65) or 7.5% (if you are 65 or older) are actually deductible.That is an itemized deduction. Itemized deductions provide no tax benefit until all of them added together are more than your standard deduction.
