A Health Flexible Spending Account (FSA) is a type of pre-tax benefit account where you can set aside pre-tax dollars to pay for eligible medical expenses.
FSAs are pre-funded, meaning that employees can access their full election amount on the first day of the plan year. Employee contributions are then collected through pre-tax deductions throughout the year to repay the employer for those upfront costs.
FSA funds are "use it or lose it." Funds expire if they are not used by the end of the plan year unless the company offers extension options like a rollover, runout period, or grace period.
To offer an FSA with Gusto, your company must offer health insurance with Gusto. If your company offers an HSA through a third party, admins can set up benefit deductions for your team.

Who's eligible
Any employee who’s eligible to participate in health benefits with your company is eligible to participate in the FSA. This means:
Who's ineligible
Per the IRS, some individuals are not eligible to participate in an FSA:
Eligible expenses
Health FSA funds can be spent on eligible medical, dental, vision, and pharmacy expenses incurred during your Health FSA policy year. For example, if your Health FSA is active from Jan 1, 2024–Dec 31, 2024, you cannot pay for services rendered in 2023.
Here are a few resources about eligible expenses:
If you're enrolled in a Limited Purpose FSA, you can only use your funds for eligible dental and vision expenses. Medical and pharmacy expenses will not be allowed.
Eligible dependents
Outside of yourself, FSA funds can be used on eligible expenses for eligible dependents defined by IRS Publication 969.
These dependents are generally:
Since Health FSA contributions are pre-tax, the IRS sets annual contribution limits.
Here are the maximum annual limits for Health Flexible Spending Arrangements (including limited-purpose FSAs):
Both the employer and employee can contribute up to the IRS max. For example, if both you and your employer contribute the max $3,200 for 2024, your account balance will be $6,400.
The limit also does not include rollover amounts. If your employer allows a rollover, your rollover amount is added to your election for the new plan year.
If you have two FSAs in one calendar year due to an employer change, you may contribute more than the IRS limit.
Employers can but are not required to contribute to employee accounts.
Eligible employees choose how much they want to contribute during open enrollment. Their contribution is also known as their election.
If you want to know how much you've contributed to your Health FSA, check your paystub or the Benefits section of your Gusto account.
The annual amount you choose to contribute during your enrollment is locked in for the company’s policy year. Your total election amount is divided by the number of regular payrolls your company will run during the policy year and deducted evenly from your paychecks. Health FSA elections cannot be changed unless you experience a qualifying life event.
If you experience a qualifying life event and think you're eligible to change your Health FSA contribution, please reach out to [email protected]. Include which qualifying life event you experienced, documentation of the event, and the new contribution amount you'd like.
Keep in mind that if you want to lower your contribution amount, it can only be lowered up to the amount that has already been used or contributed, whichever is larger.
FSAs are pre-funded, meaning employees can start spending up to their full election amount on the first day of the plan.
Employee contributions are deducted pre-tax from payroll. The employee's annual election amount (the contribution amount they chose for the plan year) is evenly distributed across each payroll in the plan year.
If a deduction is missed, the remaining amount owed is redistributed over the remaining payrolls in the policy year.
If an employee leaves the company before the end of the plan year and already spent their full Health FSA balance, the company forfeits whatever amount has not yet been deducted from their paychecks.
There are many differences between the two, but one of the biggest distinctions is that funds in an FSA will expire if they're unused during a plan year, while the HSA funds can be used beyond the plan year.
FSA: Employees can make pre-tax contributions to their FSA accounts, which are pre-funded by the employer and repaid through payroll deductions. Money in FSAs can be used to cover eligible expenses and must be used before the end of the plan year. This is known as the “use it or lose it rule”.
HSA: A pre-tax benefit account for people who are enrolled in a high-deductible health plan (HDHP). Pre-tax dollars are contributed to the account and accumulate each year that you’re enrolled without expiring. These funds can be used to cover eligible medical expenses and investments.

There are two types of Health FSAs:
If you and/or your spouse contribute to a Health Savings Account (HSA) during the Health FSA plan year, you are only eligible for an LPFSA.
When you enroll in a Health FSA in Gusto, we'll ask if you or your spouse plan to contribute to a Health Savings Account in the upcoming policy year. If so, you'll be enrolled in an LPFSA.
If you're not sure what kind of Health FSA you have, check out your plan details in the Benefits section of your Gusto account.
| General purpose FSA | Limited-purpose FSA |
Eligible medical expenses | ✓ |

Eligible vision expenses | ✓ | ✓ |

When an employee sets aside pre-tax money for a Health FSA, their gross taxable income is lowered. Since employers are taxed for FICA on the amount an employee earns, employer taxes are also reduced.
Here's what benefit admins need to know about setting up a Health FSA in Gusto.
Here are the company fees to offer an FSA with Gusto:
To set up a Health Flexible Spending Account through Gusto, your company must also have Gusto-brokered medical insurance or use the broker integration. If you already have benefits with Gusto, you can only add a Health FSA at your next renewal.
To set up medical coverage and a health FSA, check out this article.
If you offer an FSA through a third party, you can set up payroll deductions for your enrolled employees.
Follow these steps if your company offers a Health FSA you'd like to transfer to Gusto. You must offer medical benefits through Gusto or use the broker integration to offer a Gusto Health FSA.
Before you begin, you'll need a list of currently enrolled employees, their balances, and year-to-date contributions. Reach out to your current Health FSA provider if you need help finding this.
Once you complete the steps in Gusto, we'll start setting up your benefit and contact you with next steps.
Non-discrimination testing is a method you can use to make sure your benefits don’t favor highly compensated or key employees. For Flexible Spending Accounts (FSAs), a common test to use is the key employee concentration test. For Dependent Care Flexible Spending Accounts (DCFSA), both the key employee concentration test and the average benefits test are commonly used. You are encouraged to check with your tax expert and/or legal counsel to confirm which tests are necessary for your company.
We suggest that you run non-discrimination tests three times during your policy year to avoid any issues with the IRS:
If you have concerns about failing these tests throughout the policy year, you should check with your tax expert and/or legal counsel to determine which of the options below is best for you. Then reach out to our team so we can help make changes to your benefits. Here’s what we may recommend:
The key employee concentration test requires that, of your employees’ total annual benefit amount, 25% or less of this amount comes from your key employees’ benefit totals. The total annual benefit amount includes pre-tax premiums of all lines of coverage, such as medical, dental, and vision, for both employees and dependents. If none of your company’s key employees opt into the Health FSA, your company passes this test automatically.
If key employees account for greater than 25% of the total annual benefit amount, you are likely to fail the key employee concentration test at the end of your policy year
A key employee is defined by the IRS as:
The average benefits test applies in a variety of situations, but for Gusto customers it’s especially important for DCFSAs. This test requires that the average election amount for the DCFSA of non-highly compensated employees be at least 55% of the average contribution amount for the DCFSA of highly compensated employees.
It can be difficult to predict whether your company may pass or fail this test until open enrollment is over, as it is based solely on your employees’ choice to opt into (or out of) the Dependent Care FSA. It can also be difficult to predict throughout the duration of your policy year, as any new hires opting in (or terminated employees losing this benefit), can also affect your pass/fail result at the end of your policy year.
A highly compensated employee, as defined by the IRS, is identified as an employee:
If everyone at your company owns more than 5% of the company and/or the majority of the team earns more than $120k, the DCFSA may not be the best benefit for your company.
Employees who satisfy the following criteria do not count toward the top-paid group:
Note: This article is for general and educational reference only and is accurate as of April 1, 2019. Since IRS laws are complex and change frequently, we'd recommend working with a tax professional to perform non-discrimination testing.

After your plan year ends or if you leave your company, you may have extra time to submit expenses for reimbursement.
To confirm your deadline to submit an expense for reimbursement: Sign in to your Gusto employee account, then go to the Benefits section. Click the FSA tile, then access your Gusto Benefits Card Hub.
If your plan year has ended or your company has canceled the Health FSA, you may still have access to your Health FSA funds via the runout period, grace period, or rollover.
If your company is moving off of Gusto or has found a new broker, connect with your employer on whether your FSA will be moving as well. In either of these situations, you will not be able to submit expenses for reimbursement after the plan has ended.
At the end of your company’s plan year, you have 90 days to submit claims for services rendered during your previous plan year. This is called the runout period.
Your reimbursement request(s) must be for services rendered during your eligible coverage period. If you have two accounts that are eligible for reimbursements, you will submit a reimbursement request separately.
In addition to the runout period, your plan either has a grace period or a rollover. Check the Health FSA tile in the Benefits section of your Gusto account to see if your plan has this and your last day to submit claims.
If your company offers a grace period, this extends the time period in which you can use your health FSA funds for new expenses. A grace period is typically 2 months and 15 days.
Although most funds in your FSA are "use it or lose it," if your company offers a rollover, you may be able to roll some funds over from one year to the next (only if you renew your Health FSA). If your company offers a rollover and you renew your Health FSA for another plan year, a rollover is an amount of money that can roll over from one policy year into the next.
The maximum an employer can allow an employee to rollover for a plan starting in 2024 is $640. The rollover limit for a plan starting in 2025 is $660.
During the 90-day runout period, if your company offers a rollover, you may submit claims for previously rendered services and use your card for new expenses incurred. You can only use your rollover by submitting a claim. Using your card will draw from your current plan year's funds and the transaction will later be denied. Then you'll have to repay the balance before submitting the transaction as a claim for reimbursement.
After the runout period, grace period, and or rollover any remaining funds in your Health FSA are forfeited to your company. (As set by the IRS. See Publication 969.)
A Health FSA is terminated on the last day of employment. Funds are "use it or lose it," meaning any leftover funds after the runout period are forfeited to the employer. If an employee leaves the company before the end of the plan year and already spent their full FSA balance, the company forfeits whatever amount has not yet been deducted from their paychecks.
A dismissed employee has 90 days from the last day of employment to submit claims for any eligible services rendered during the policy period. The policy period starts on the effective date of the FSA and ends on the last day of employment. For example, if your last day of work is November 1st, you have until January 30th to submit claims. Those claims must be for eligible expenses that you incurred during the policy period and on or before November 1st.
After the 90-day runout period, any remaining funds left in your account are forfeited to your previous employer. Employers may not cash out any remaining FSA balance to employees.
