You can treat your HSA like an individual retirement account, or IRA, for health care. That’s because you can save the money in it and use it for qualified expenses at any time.

According to recent estimates, a married couple retiring at age 65 will require approximately $280,000* to cover medical costs such as out-of-pocket prescription drug expenses and Medicare premiums. By saving money in an HSA you can prepare for your family's future health care costs and also use your HSA as a buffer to protect your other retirement accounts from out of pocket medical expenses.
