Who is eligible to establish a HSA?
In any specific month, an eligible individual: 1) is covered under a high deductible health plan on the first day of such month; 2) if covered by an additional health plan, said plan must be an HDHP (with certain exceptions for plans providing certain limited types of coverage).; 3) is not enrolled in Medicare (generally, has not yet reached age 65); and 4) may not be claimed as a dependent on another person’s tax return.
