HSAs are a form of medical savings account, similar to the now-familiar IRAs. These accounts are the property of the employee and can accumulate interest and dividends like other savings vehicles. Funds that are not used for health care-related expenses can be used for retirement living and can also be willed to one’s heirs. When combined with a high-deductible health insurance policy, an HSA replaces traditional health insurance coverage – and does so in a way that results in a more consumer-driven approach to health care.
