If you are eligible, you can establish an HSA in much the same way you would establish an IRA – with a qualified custodian. Each year, you are responsible for determining your allowable annual HSA contribution and whether you have qualified medical expenses eligible for reimbursement with nontaxable HSA distributions. (include chart from HSA brochure)
Additionally, a “catch-up” contribution is available for eligible individuals who are age 55 or older by the end of their taxable year and have not enrolled in Medicare.
If you meet the eligibility requirements for an HSA, you, your employer, your family members, and any other person (including non-individuals) may contribute to your HSA. This is true whether you are self-employed or unemployed.
