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).
Health Savings Accounts (HSA) must be established by the tax filing deadline (without extensions) for the tax year in which your qualifying contribution(s) will apply. 1  Any eligible individual can contribute to an HSA. For an employee's HSA, the employee, the employee's employer, or both may contribute to the employee's HSA in the same year as long as the aggregate contributions are under the contribution limit. Family members (or any other person) may also make contributions on behalf of an eligible individual. Contributions must be made in cash.
