An HSA is a portable account that belongs to the individual, not the employer. When changing jobs or retiring, you can keep your existing HSA and continue to use the funds for qualified medical expenses. You can also choose to roll over the HSA funds into a new HSA with a different provider. If you enroll in Medicare after age 65, you can no longer contribute to an HSA, but you can still use the existing funds for qualified medical expenses tax-free. Unused HSA funds can also be used for non-medical expenses after age 65, subject to ordinary income tax but without penalties.
