This bill makes significant changes to Health Savings Accounts (HSAs), which are special savings accounts that let people set aside pre-tax money to pay for medical expenses. The main change is dramatically increasing how much money you can contribute to an HSA each year—instead of the current fixed dollar limits, you'd be able to contribute up to the same amount allowed for 401(k) retirement plans, which is much higher and adjusts annually for inflation. People age 50 and older get an additional catch-up contribution, similar to retirement account rules.

The bill also expands what counts as a qualified medical expense you can pay for with HSA money. It adds coverage for primary care services through fixed-fee arrangements (like concierge medicine), allows you to cover young adult children up to age 27, and newly permits spending on wellness-related items like dietary supplements, gym memberships, and fitness trackers. You'd also be able to use HSA funds to reimburse medical expenses from the previous year, even if you hadn't opened the account yet when you incurred the expense.

Additionally, the bill makes HSAs more flexible for families and employers. It allows HSA funds to pass to more family members after death (not just spouses, but also children, parents, and grandparents), and it requires employers who contribute to employee HSAs to make comparable contributions to all employees in the same situation. The bill also protects HSAs in bankruptcy by treating them like retirement accounts. Overall, this legislation aims to make HSAs more attractive and accessible as a way for people to save money on healthcare costs while getting tax benefits.
