A health care FSA (Flexible Spending Account) is an employer-sponsored, tax- advantaged account you use to pay for eligible out‑of‑pocket medical, dental, and vision costs with pre‑tax dollars.

What is a health care FSA?

  • It’s an account you choose to fund through automatic payroll deductions before taxes are taken out.
  • You then use the money for qualified expenses like copays, deductibles, prescriptions, and many over‑the‑counter items, plus dental and vision care.
  • Many plans give you an FSA debit card so you can pay directly at pharmacies, doctors, or online retailers that accept FSA cards.

Think of it as a short‑term, tax‑friendly wallet for your regular health costs during the year.

How it works (simple steps)

  1. Decide how much to contribute
    • Once a year (usually during open enrollment), you pick an annual contribution amount, up to an IRS‑set limit (for many plans around a few thousand dollars per year, such as 3,300 USD for 2025 in some health FSAs).
 * Your employer spreads this amount over your paychecks and deducts it pre‑tax.
  1. Use the funds for eligible expenses
    • You pay for eligible expenses with your FSA card or pay out of pocket and submit a claim for reimbursement.
 * Eligible expenses usually include:
   * Doctor and hospital copays and deductibles
   * Prescription drugs
   * Many over‑the‑counter medications and medical supplies (subject to IRS rules)
   * Dental care (cleanings, fillings, orthodontia)
   * Vision care (eye exams, glasses, contacts)
  1. Tax savings
    • Because contributions are made before income and payroll taxes, you lower your taxable income and effectively get a discount on those health costs.

Aspect Health Care FSA Benefit Potential Drawback
Tax savings Contributions are pre‑tax, reducing income and payroll taxes.If you contribute more than you spend, you may forfeit unused funds.
When funds are available Most health care FSAs make your full annual election available at the start of the plan year.If you leave your job mid‑year, rules can limit access to remaining funds.
Eligible expenses Covers broad medical, dental, and vision expenses not fully covered by insurance.Not for long‑term savings; funds are meant for near‑term health spending.
Employer contributions Some employers may add money to your FSA on top of your own contributions.Employer contributions are optional; many employers do not add anything.
Plan deadlines Some plans offer a grace period or allow a small carryover of unused funds into the next year.You must track deadlines and rules carefully to avoid losing unused money.

“Use it or lose it” and deadlines

  • Health care FSAs generally follow a “use it or lose it” rule: money left unused after the plan’s deadline can be forfeited.
  • Employers may pick one of these IRS‑allowed features (or neither):
    • A grace period (often up to 2.5 months into the next year) to keep spending last year’s funds.
* A limited **carryover** of remaining funds into the next plan year, up to an IRS‑set cap.

How it compares to other accounts

  • Health FSA vs HSA : An HSA must be paired with a high‑deductible health plan and the money can roll over year after year, while a health FSA is more “spend this year or soon after” and is tied to your employer’s plan.
  • Limited‑purpose FSA : Some people with an HSA can also have a limited‑purpose FSA that only covers dental and vision, so they keep HSA eligibility.

Mini example

Imagine you elect 2,000 USD for your health care FSA this year.

  • Your taxable income is reduced by that amount, so you pay less tax.
  • In March, you have a 600 USD dental bill and a 150 USD pair of prescription glasses; you pay both from the FSA, effectively using pre‑tax money for those costs.
