This legislation, titled the WEAR IT Act, proposes to expand the types of medical expenses eligible for reimbursement or payment through various tax-advantaged health accounts. Specifically, it amends the Internal Revenue Code of 1986 to permit the use of funds from health savings accounts (HSAs) , Archer Medical Savings Accounts (MSAs) , health flexible spending arrangements (FSAs) , and health reimbursement arrangements (HRAs) for the purchase of certain wearable devices. The bill defines a "wearable device" as a device or software worn on the body, or used with such a device, that either collects and analyzes physiological data for the diagnosis, treatment, or prevention of a health condition, or assists in rendering a diagnosis or providing treatment. A key provision limits the amount that can be spent on these devices to $375 per taxable year across all specified account types. These changes are slated to take effect for amounts paid or expenses incurred after December 31, 2025.
