Itâs Not Too Late to Maximize Your 2016 HSA Contributions: Contribute Until April 17, 2017. One of the big pros of enrolling in a high-deductible health plan is that it is paired with a Health Savings Account (HSA).

HSAs are paired with high-deductible health insurance plans. Contributions to an HSA are tax-deductible in the adjustments to income section of Form 1040. Contributions for a particular tax year are due by April 15th (the same day as the deadline for the filing the Form 1040). A person can contribution savings for the tax year 2016, for example, from January 1, 2016, to April 15, 2017. Earnings, such as interest and dividends, in the health savings account, are tax-exempt at the federal level.
