Most adults under 65 who are not enrolled in Medicare and are covered under a high-deductible health plan (HDHP) can qualify for an HSA, but it is up to the account holders to determine their own eligibility.
There are no eligibility restrictions regarding income level and there is no requirement of earned income to make contributions.
*Consult a tax advisor.
**When used for qualified medical expenses. Consult a tax advisor. Qualified expenses include most medical care and services, dental and vision care, weight loss programs, some over the counter medications, mileage, and more.
***You can withdraw funds at any time for any purpose. However, if funds are withdrawn for reasons other than qualified medical expenses, the amount withdrawn will be included as taxable income, and is subject to a 10% penalty tax.
