Millicent Fairchild is a single orthopedic surgeon based in Scottsdale, Arizona, who earns a substantial hospital salary in addition to income from her private consulting practice organized as a sole proprietorship. During 2024, she also sold appreciated shares of a biotech fund held long-term, generating a capital gain, and received modest interest and dividend income from her brokerage accounts. Her above-the-line deductions reflect self-employed health insurance premiums and one-half of her self-employment tax, while her itemized deductions include significant state and local taxes (capped at $10,000), mortgage interest on her primary residence, and charitable contributions to a local hospital foundation.
