4. Plastic Surgery

Plastic surgery done to enhance your looks (e.g., facelifts, electrolysis, liposuction, etc.) is not a tax-deductible expense.
On the other hand, if the plastic surgery you undergo is medically necessary, for example, getting a nose job to correct a deviated septum causing difficulty breathing, frequent sinus infections and/or heavy snoring, then, yes, it is a tax-deductible expense.
Plastic surgery used to correct an injury incurred from an automobile accident, animal bite or other traumatic accident is also considered tax-deductible, as congenital abnormalities cause deformities.
3. Family Pet

We know pets can be expensive, but nine times out of ten, the bills they incur will not be tax-deductible. The exception to that will be if the pet is actually a service animal.
According to an article published by Bankrate, “the cost of buying, training and maintaining a guide dog or other service animal for someone who has a physical disability is tax-deductible. This generally includes any expenses incurred to maintain the animal — including for food, grooming and veterinary care — so that it can perform its duties.”
