Contributions to an HSA are deductible from gross income (page 1 of Form 1040) even if you don’t itemize other deductions. You must file Form 8889 with your return if you had any activity in the account for the year—contributions in Part I and/or distributions in Part II. Distributions are not taxed if you used the money to pay qualified medical costs not covered by insurance. If you used the money for anything else, you’re taxed on the distribution and, if under age 65, subject to a 20% penalty reported on Form 5329.
Retirement plan set up by a self-employed person, providing tax-deductible contributions, tax-free income accumulations until withdrawal, and favorable averaging for qualifying lump-sum distributions.
