Health Care Flexible Spending Account

A Health Care Flexible Spending Account (FSA) is a pre-tax benefit account used to pay for eligible medical, dental, and vision care expenses that aren’t covered by your insurance plan or elsewhere. It’s a smart, simple way to save money while keeping you and your family healthy.

Although your MIT health and dental plans will cover much of your health care costs every year, you will probably have to pay some portion of your health care expenses out of pocket. The MIT Health Care Flexible Spending Account (FSA) is a voluntary account offered by MIT and administered by WageWorks that makes it possible for you to set aside money from your pay to cover some of the health care expenses not covered by your health plan. The money you contribute — up to the annual limits set by federal law (minimum $104, maximum $3,200 in 2024) — is not taxed as income, and there is no tax or penalty when you use the money for eligible health care expenses.

Access Your Account

MIT's FSAs are administered by HealthEquity (formerly WageWorks). The button below will take you to their site, where you can choose to log in to either WageWorks or HealthEquity. If you have previously used a WageWorks account to log in, you can continue to log into WageWorks for now. If you are new to HealthEquity/WageWorks, please set up a new account under HealthEquity. See login help.



You are eligible for an MIT Health Care FSA if you are paid by MIT, are appointed to work at MIT for at least three months, and work at least 50% of the normal full-time work schedule.

Who is not eligible
  • contractor
  • affiliate
  • teaching or research assistant (see graduate student benefits)
  • honorary lecturer
  • summer appointment
  • international visiting student
  • member of the armed services assigned to MIT
  • family member who is not employed by MIT
  • work-study student
  • paid by MITemps
Members of collective bargaining units

All the plan provisions are subject to the terms of your collective bargaining agreement.

How the plan works

You have access to the entire election amount on January 1 of each plan year, even though the dollars have not been deducted from your paycheck yet. You must have a qualifying medical expense to gain access to the funds, and your deductions will continue to come out of your paycheck on a weekly or semimonthly basis throughout the remaining plan year.

When you, your spouse, or dependent children pay for an eligible expense, you are reimbursed through your account. You cannot be reimbursed for the expenses of domestic partners.

You can submit claims for reimbursement up until April 30 each year for eligible services received through December 31 of the previous plan year.

Your pay and the MIT Health Care FSA

When you make contributions to your MIT Health Care FSA, you receive certain tax benefits on the money you contribute to your account. By setting aside money for these expenses before taxes, you will generally pay less in federal, state and Social Security taxes.

Participation in an MIT Health Care FSA will not affect your salary for the purposes of

  • annual salary reviews
  • 401(k) participation
  • life insurance coverage
  • disability benefits

Use it or lose it

Be as accurate as you can in estimating your annual eligible expenses, so that you do not contribute more to your MIT Health Care FSA than you expect to claim for reimbursement. Any money left in a Health Care FSA that is not part of the $610 carryover amount you automatically lose after April 30 following the plan year. Use the WageWorks FSA Calculator tool located on WageWork's website to help you determine how much money you would like to set aside in either account. You may not use this money for any other purpose or transfer the money to any other account.


The Health Care FSA Carryover feature allows up to $610 from one plan year to be carried over into the following plan year. The MIT Health Care FSA has a carryover time limit to no more than one plan year when a subsequent enrollment is not made. As long as you have an active Healthcare FSA in subsequent plan years, you may carryover funds from one plan year to the next.

  1. Who is eligible for the Carryover?
    Active employees with a Health Care FSA who have unused funds in their account as of December 31 will have their carryover funds carried over into the next plan year automatically. However, if the employee does not re-enroll in a Health Care FSA, the carryover dollars must be used by December 31 following the year in which a Health Care FSA was elected.
  2. How much can/will be carried over?
    Any remaining balance up to $610 will be carried over. 
  3. Does the carryover apply to the Dependent Care FSA?
    No, the carryover only applies to the Health Care FSA. It does not apply to the Dependent Care FSA.
  4. If I do not elect a Health Care FSA for 2024, but I have leftover Health Care FSA funds from 2023, will those funds be carried over into a 2024 FSA?
    Yes, for active employees, even if you do not elect a Health Care FSA for 2024, any funds remaining in your account up to a limit of $610 will be carried over for you to use until December 31, 2024.
  5. I elected to contribute $3,050 (the maximum allowed amount) into the Health Care FSA for the 2024 plan year. If I have funds from my 2023 Health Care FSA to be carried over, won't my Health Care FSA exceed the $3,200 maximum?
    Yes, but it is allowable for your Health Care FSA account to exceed the $3,200 maximum annual deferral as long as no more than $3,200 is deducted from your pay on an annual basis.

Medical practitioner's notes vs. prescriptions

What's the difference between a Medical Practitioner's note and a Prescription for over-the-counter (OTC) medicines and drugs, and when is each required?

Medical practitioner (doctor's) notes:
  • For some expenses (for example, dietary supplements), a letter of medical necessity (below) is required to verify that the expense qualifies as medical care.
  • To be allowable, a letter of medical necessity may be written by a doctor of medicine, dentistry, podiatry or optometry; an authorized chiropractor, an alternative healer; or other qualified medical practitioner.
  • A letter of medical necessity must contain all of the following items:
    1. date
    2. patient's name
    3. medical practitioner's name
    4. statement of medical necessity
    5. the prescribed treatment
    6. the duration of treatment required
  • WageWorks will keep a copy of valid letters on file so it is not necessary to include previously submitted notes with each submission.
Prescription for OTC medicines and drugs:

OTC medicines and drugs require a physician's prescription to be eligible.

  • A valid prescription is an electronic or written order for a medicine or drug that meets the legal requirements of a prescription in the state in which the medical expense is incurred, and that is issued by an individual authorized to issue a prescription in that state.
  • Due to its interpretation of IRS rules, WageWorks will NOT keep a copy of prescriptions on file. For OTC medicines and drugs, you must submit your prescription with each submission.
  • You may submit the same prescription as many times as the prescription allows (for example, three times if three refills are prescribed).
