Contributions

Your contribution as an employee

Each year you’re enrolled in the HSA, you’re required to contribute a minimum of $300 and can make additional contributions up to the IRS limit.

You can calculate your contribution limits by subtracting IU’s contribution from the IRS limit:  

  • For 2026: Between $300 and $3,400 for employee-only coverage / $6,750 for all other coverage levels
  • If you’re age 55 or older, you can contribute the additional $1,000 “catch-up” above these amounts.
  • Your contributions are made through pre-tax payroll deductions, spread equally across your paychecks.
  • Unlike the flexible spending account, your full balance rolls over each year, even after you leave the university or retire.

 It’s important to keep in mind that all contributions to your HSA during the year (yours and IU’s) must stay within the IRS limits. If you lose eligibility mid-year, your contribution limit may be prorated for the months you were eligible, and any excess contributions must be removed or declared taxable.

Want to change the amount of your payroll contribution?

You can change, suspend, or stop HSA contributions at any time during the year by submitting an Optional Benefit Change online or a paper HSA Enrollment/Change Form to IU Human Resources.

 Your new annual contribution amount must fall within the plan’s minimum and maximum limits and cannot be less than what you’ve already contributed (refunds are not provided under the plan). Your new deduction amount will be automatically recalculated and spread evenly over your remaining pay periods by subtracting your new contribution by what you've already contributed, then dividing by the number of remaining pay periods.

Special circumstances

You will be able to continue contributing to the health savings account.

The maximum amount you are permitted to contribute will be the greater of the maximum annual HSA contribution based on your HDHP coverage on the first day of the last month of your tax year (December 1st), or the amount that results when you prorate appropriately for the number of months you were enrolled in each coverage level.

If you and your spouse are both benefits-eligible IU employees, you can choose one shared plan or separate plans for medical coverage and HSAs.

Option 1: Enroll together in employee plus spouse or family coverage under the higher-paid spouse.

  • Premiums are based on the higher-paid spouse’s salary band and chosen plan.
  • If that spouse enrolls in IU’s high deductible medical plan, they can open an HSA and contribute up to the family maximum (plus the catch-up if they are age 55 or older). They will also receive IU’s contribution for family coverage.

Option 2: Enroll separately in employee-only coverage.

  • Each of you will pay the premium for your individual salary band and plan.
  • If you also need to cover children, then one spouse should enroll in employee-only coverage, and the other in employee plus child coverage. It doesn't matter which parent enrolls them, as long as each child is only enrolled once.
  • If both of you enroll in IU’s high deductible medical plan:
    • You can each open your own HSA and contribute up to the maximum (plus the catch-up, if you are age 55 and older). You will also each receive IU’s contribution for your coverage level.
    • Important caveat: If either of you covers children, then your combined  contributions across both of your HSAs cannot exceed the family contribution limit.

While turning age 65 does not change your HSA eligibility, enrolling in Medicare or Social Security does. Learn why you don’t have to enroll in Medicare until you retire (regardless of your age) and about your options for your HSA if you’ve already enrolled: How enrolling in Medicare can affect your HSA.

Your per-paycheck contribution is calculated based on 12 or 26 pay periods. Because you don’t receive paychecks during two months of the year, your remaining balance will be automatically recalculated when you return and spread evenly over your remaining pay periods. IU will still make its contribution in July, even though you won’t receive a paycheck that month.

You can add funds to your HSA outside of IU payroll by transferring money from a personal bank account directly to your HSA or by mailing a check to WEX with the required contribution form. Contributions made on an after-tax basis can be deducted from your gross taxable income when you file your tax return. Remember to track all contributions—university, payroll, and personal—to ensure you don’t exceed the IRS limit.
