The purpose of this legislation, known as the "Catch Up Act," is to update the tax code to allow both spouses in a married couple to contribute to the same health savings account (HSA) in a more flexible way. This change is aimed at helping families better manage their healthcare expenses by maximizing their savings in HSAs. The key provisions of the Catch Up Act include allowing married couples who both have family coverage under a high-deductible health plan to combine their contributions to a single health savings account.
