Any adult can contribute to an HSA if they:
- Have coverage under an HSA-qualified “high deductible health plan” (HDHP)
- Have no other first-dollar medical coverage (other types of insurance like specific injury insurance or accident, disability, dental care, vision care, or long-term care insurance are permitted).
- Are not enrolled in Medicare.
- Cannot be claimed as a dependent on someone else’s tax return.
Contributions to your HSA can be made by you, your employer, or both. However, the total contributions are limited annually.
HSA contributions can be deductible (even if you do not itemize deductions) when completing your federal income tax return. Interest earned on funds in an HSA account and withdrawals are tax-free when used to pay for qualified medical expenses.
Contributions to the account must stop once you are enrolled in Medicare. However, you can keep the money in your account and use it to pay for medical expenses tax-free.
