An Analysis of the Medical Expense Deduction Post-O'Donnabhain
ABSTRACT In 2010, the United States Tax Court upheld a taxpayer's deduction for medical expenses arising from gender reassignment surgery. This article discusses the facts of the O'Donnabhain case and the Tax Court's holding in light of relevant legislative history, and finds that a new layer of understanding now exists in the context of deductible plastic surgery: in a post-O'Donnabhain world, mental (not just physical) diseases may be treated through physical alterations to the body and give rise to deductible medical expenses. Based on the Tax Court's opinion, we posit an algorithm for application of what we consider to be a fourth case law-created exception to the disallowance of deductions for cosmetic surgery, which may have application in both LGBT- and non-LGBT-related instances.
