Oh yeah, it's all tax deductible IF you itemize, etc. like Jan pointed out.
I had my AN surgery and plenty of expenses in 2009, so I checked with a friend who is a tax accountant and it is crazy what all you can claim. That is why I haven't gotten my taxes done yet this year. Got to get ALL KINDS of stuff together for medical and pretty sure I will have more than the 7.5% last year since I had not income for 3 months either. My specialists and surgery was almost 3 1/2 hr away so MILEAGE too
Was told too that I could have added all the eye drops, etc. that we had to pay for too, but I didn't know then....so have no receipts.
Was told to BE SURE to just keep all receipts for this year because if I do any hearing device, that counts too. Batteries, cleaning supplies, etc....YES! I was even told over the counter meds. Also, get mileage for the trips, so was able to just mapquest my route to visits and it is so many cents per mile round trip to ANY medical related stuff. (I even mapquested my local eye doctor appointments and Physical therapy.....why not? It all counts)
REMINDER for sure: You can ONLY claim what you PAID in that tax year, not what you were billed.
Now, this is all from my person & recommend checking with an accountant/CPA of your own.....of call/email IRS if questions!
