This calculator will help you to determine how much, if anything, you can contribute to a Health Savings Account (HSA). A HSA is a tax-exempt trust or custodial account that you set up with a U.S. financial institution in which you can save money exclusively for future medical expenses. This account must be used in conjunction with a High Deductable Health Plan (HDHP).
Reference: For a full description of HSAs please refer to IRS Publication 969 (2018), Health Savings Accounts and Other Tax-Favored Health Plans.
