The Personal Health Investment Today Act of 2025 aims to amend the Internal Revenue Code of 1986, allowing certain physical activity, fitness, and exercise expenses to be treated as amounts paid for medical care. This legislative change is intended to promote public health and prevent diseases, particularly those linked to being overweight or obese. By providing financial incentives, the bill seeks to encourage healthier lifestyles and increase participation in physical fitness activities. Specifically, the bill introduces **"qualified sports and fitness expenses"** which encompass amounts paid exclusively for participating in physical activity. These expenses can include membership fees for fitness facilities, costs for instruction or participation in physical exercise, and certain equipment used in physical activity programs. An **overall dollar limitation** is set at $1,000 per taxpayer, or $2,000 for those filing a joint return or as a head of household. The bill also defines specific criteria for qualifying fitness facilities and imposes limitations on equipment, such as requiring exclusive use for physical activity and capping single sports equipment items at $250.
