A health savings account (HSA) is a tax-advantaged savings account available to those who are enrolled in a high-deductible health plan (HDHP). The funds contributed to an account are not subject to federal income tax at the time of deposit. Unlike a flexible spending account (FSA), funds roll over and accumulate year to year if not spent. HSAs are owned by the individual.
