Any eligible individual may establish an HSA. Eligibility is determined on a monthly basis. To be eligible, an individual must meet all of the following requirements: Covered under a high deductible health plan (HDHP) on the first day of the month; generally not covered by any health plan that is not an HDHP (exceptions exist for coverage that is not part of an HDHP for accidents, disability, dental care, vision care, long-term care, or permitted insurance); not enrolled in Medicare; and not able to be claimed as a dependent on another person’s tax return. The owner of an HSA is called the "HSA owner." Note: Permitted insurance is insurance under which substantially all of the coverage provided relates to liabilities incurred under workers’ compensation laws, tort liabilities, liabilities relating to ownership or use of property (e.g., automobile insurance), insurance for a specified disease, or illness and insurance that provides a fixed payment for hospitalization.
