The annual amount is contributed on a per pay basis. In order to get the employer contribution to the HSA, you must Select the HSA benefit plan even if you choose to contribute zero dollars yourself. If you choose Waive, you will not get the employer contribution To contribute to an HSA account, you cannot be enrolled in Medicare, Medicaid or Tricare. IRS 2026 Maximum Contributions – includes both employee and employer contributions A Health Savings Account (HSA) is a consumer-oriented, tax- advantaged savings account that is always combined with a High- Deductible Health Plan (HDHP). It is an interest-accruing account, like an Individual Retirement Account (IRA), which provides financial control over how you spend your health care dollars and can be used to pay for your out-of-pocket medical expenses. HSA earnings grow tax-deferred and qualified withdrawals are tax-free without “use it or lose it” provisions found with a Flexible Spending Account (FSA). Money not used in your Health Savings Account can be rolled over to the following year. HSA funds can be used for all qualified medical expenses, including medical services, as well as eyeglasses, dental procedures, prescription drug coverage and over-the-counter medications provided you submit a prescription from your provider. See IRS Publication 969 for more information and a listing of Qualified Eligible Expenses at www.irs.gov. If You Will Be Turning 65 Active employees turning 65 have the option to accept or decline enrollment in Medicare, including Medicare Part A. • Employees who accept enrollment in any part of Medicare are no longer eligible to make or receive contributions to an HSA. • If you elect Medicare at age 65, your maximum HSA contribution for the year you elect will be prorated by the number of months you were not enrolled in Medicare. • Employees who decline enrollment may continue to make and receive contributions to an HSA. • Qualified distributions remain tax free regardless of your eligibility to contribute. • Non-qualified distributions are taxable but no longer carry a 20% penalty after age 65. • Medicare Part(s) A, B, D and Medicare HMO premiums may be paid or reimbursed with tax-free HSA dollars. You cannot use your HSA to pay for Medigap premiums.
