The IRS use-or-lose rule and what it means for FSAs

August 28, 2024

The IRS’ use-or-lose rule governs flexible spending accounts (FSAs). This rule is one of the big differentiators between FSAs and other types of employee benefits. So what is the use-or-lose rule? And what does it mean for the upcoming plan year? We’ll answer those questions and more. 

 

What is a FSA?

flexible spending account (FSA) is an employer-sponsored benefit that allows employees to set aside a portion of their pre-tax salary to pay for qualified medical expenses or dependent care expenses. These are designed to help participants save money on eligible out-of-pocket healthcare or childcare costs by reducing their taxable income. Participants decide how much to contribute to the FSA each year, and their funds can be used for a wide range of eligible expenses

 

What is the use-or-lose rule and how does it work? 

The IRS’ use-or-lose rule states that FSA funds must be spent by the participant within the FSA’s plan year. That means FSA participants typically need to spend most or all of their FSA funds by the end of the plan year. Unused funds at the end of the plan year are forfeited to the plan.

 

Can any funds carry over into next year? 

Possibly. The IRS normally allows up to a $640 carryover in 2024 of medical FSA funds from one plan year to the next. Employers determine whether their medical FSAs include a carryover. 

 

What are grace periods and run-out periods?

grace period is an extension of time beyond the end of the regular plan year in which FSA participants can incur new expenses and use any remaining funds from the previous plan year. This can last up to 2½ months after the end of the plan year. 

The run-out period is a specific time frame after the end of the plan year in which FSA participants can submit claims for eligible expenses incurred during the plan year. Unlike a grace period, a run-out period does not allow for new expenses to be incurred during that period of time. A run-out period allows participants to request reimbursements for expenses they may have incurred close to the end of the plan year but haven’t submitted for reimbursement yet. 

An employer can choose to offer either a grace period or a carryover, but not both. Sometimes, an employer may pick neither, which means any remaining funds in the FSA at the end of the plan year are forfeited. 

 

Can participants change their FSA election during a plan year?

Usually, participants can only elect contributions to their FSA during open enrollment, but there are some exceptions where mid-year contributions are fine. This can include:

  • A change in marital status
  • A change in the number of tax dependents
  • Employment changes
  • Residential change (if coverage eligibility is affected)

 

Does use-or-lose apply to medical and dependent care FSAs?

Yes. The IRS’ use-or-lose rule applies to medical FSAs and dependent care FSAs

 

Does use-or-lose also apply to HSAs?

No. With a health savings account (HSA), all funds carry over from year to year. That’s one reason HSAs are “savings” accounts, while FSAs are “spending” accounts.
