An Act amending the act of March 4, 1971 (P.L.6, No.2), known as the Tax Reform Code of 1971, in personal income tax, further providing for classes of income.

HB 422 creates a new tax deduction for Pennsylvania residents who donate human organs. It allows taxpayers to deduct up to $12,000 annually for unreimbursed expenses directly related to organ donation, including travel, lodging, lost wages, and medical costs. The deduction applies only to the year the transplantation occurred, may be claimed just once in a lifetime, and cannot reduce taxable income below zero. This provision affects organ donors who incur qualifying out-of-pocket costs while living. The change takes effect for tax years beginning after December 31, 2025.
