A Health Savings Accounts (HSA) provides a tax advantage to offset health care expenses. This tax-exempt custodial account is established exclusively for the purpose of paying or reimbursing qualified medical expenses. It is available to taxpayers in the United States who are enrolled in a high deductible health plan (HDHP).
The money in your HSA remains available for future qualified medical expenses even if you change health insurance plans, go to work for a different employer, or retire.
