What’s an FSA and how do I use it?
Who is this for?

Anyone under age 65 who’s employed.
A flexible spending account or arrangement is an account you use to save on taxes and pay for qualified expenses. Other key things to know about FSAs are:
- Your employer provides and owns the account
- Only you and your employer can put money in an FSA, up to a limit set each year by the IRS
- FSAs are a “use it or lose it” account; your employer can keep funds you haven’t used by the end of the year
What makes them flexible? They give employers the most options when deciding on what spending accounts to offer.
Kinds of FSAs
Your employer will tell you which one of these FSAs is available to you.
Enrolling in an FSA
You usually sign up for an FSA once a year during open enrollment. That’s when you:
- Estimate your expenses for upcoming year
- See if your employer is contributing any money to the FSA
- Decide on the total amount you want to put in the account
A portion of that amount is then taken out of your paycheck before taxes throughout the year and put in your FSA.
Funds left over at the end of the year go back to your employer, although they can choose to:
- Let you pay expenses from the previous year for up to two and half months into the new year
- Or, carry over up to $500 from one year to the next
Using your FSA
You pay for qualified expenses using:
- A debit or credit card
- Your own money and then submitting receipts for reimbursement
When you have a health or limited-purpose FSA, the total amount is available on the first day. For example, if your employer put in $300, and you decided to contribute $600, you have $900 to spend right away. You’d pay back the $600 over the year.
When you have a dependent care FSA, you can only access your account balance. If your employer put in $300, that’s all you have on the first day.
