Physical therapists in private practice face self-employment tax on their net earnings, but can deduct clinic rent, equipment, and continuing education costs. PTs who work as traveling therapists receive per diem payments that are tax-free if they maintain a tax home. Student loan debt is significant in this field — those pursuing Public Service Loan Forgiveness (PSLF) should file taxes strategically to minimize income-driven repayment amounts. Specialization certifications (OCS, SCS, etc.) are deductible if self-employed.
