Yes, a Limited Purpose FSA can roll over unused funds into the next plan year, but only if your employer’s plan document specifically adopts the carryover provision. For 2026, the IRS caps the rollover at $680. Your employer can set a lower limit, offer a grace period instead, or offer no relief at all, in which case any leftover balance is forfeited at year-end.
The $680 Rollover Rule for 2026
LPFSA funds follow the same use-it-or-lose-it rule as any health FSA: whatever sits in the account at the end of the plan year goes back to the employer unless the plan builds in relief. The IRS allows employers to choose one of two safety valves, and a rollover is the more generous of the two.
If your plan permits it, you can carry over up to $680 of unused LPFSA funds into the 2026 plan year. That figure is the IRS ceiling; your employer can cap the carryover lower, but not higher. The rolled-over amount does not eat into your new-year contribution limit, so you can still elect the full $3,400 maximum on top of any carryover.
Carried-over dollars keep their limited-purpose designation. They remain restricted to dental, vision, and preventive care in the new plan year, which matters because that restriction is what preserves your HSA eligibility. A carryover from a general-purpose health FSA would disqualify you from HSA contributions entirely, even for a small balance. As long as the LPFSA carryover is clearly designated as limited-purpose in the plan document, contributing to an HSA in the new year is fine.
One point that catches people off guard: the rollover is not automatic just because the IRS allows it. Your employer has to adopt the carryover provision in its cafeteria plan document. If the plan is silent on the issue or explicitly excludes rollovers, unused funds are forfeited no matter what the IRS permits.
The Grace Period Alternative
The second option an employer can build in is a grace period. Rather than moving money forward, a grace period gives you extra time after the plan year ends to spend down the previous year’s funds on eligible expenses. The maximum length is two months and 15 days. For a calendar-year plan ending December 31, that means you would have until March 15 to use remaining LPFSA dollars on qualifying dental, vision, or preventive care costs. Anything unspent after the grace period closes is forfeited.
An employer cannot offer both a rollover and a grace period on the same FSA. The plan document has to pick one. Many employers pick neither, which is why checking your Summary Plan Description or asking your benefits administrator matters before you assume any cushion exists.
What Happens If Your Plan Offers Neither
If the plan document adopts neither a carryover nor a grace period, the use-it-or-lose-it rule applies without exception. Any balance sitting in your LPFSA on the last day of the plan year is forfeited to the employer. There is no appeal, no rollover into an HSA, no cash-out. The money is gone.
Leaving a job triggers the same forfeiture in most cases. Any remaining balance is lost unless the plan offers a post-termination spending window. Many plans provide a run-out period of 60 to 90 days after your last day for submitting claims, but only for expenses you incurred while you were still employed. New expenses after your coverage ends are not eligible.
How to Confirm What Your Plan Allows
The plan document controls, so that is where the answer lives. Two places to look:
- Your Summary Plan Description, which spells out whether the plan includes a carryover, a grace period, or neither, and states any employer-imposed cap below the $680 IRS maximum.
- Your benefits administrator or HR contact, who can confirm the specifics and tell you the exact deadlines that apply to your plan year.
Ask before the plan year ends, not after. Once the year closes, whatever the document says is what happens.
Spending Down Before the Deadline
If you are approaching year-end with a balance and no rollover in your plan, the LPFSA’s narrow scope is actually an advantage. Dental and vision expenses are easier to accelerate than general medical costs. Prescription sunglasses, a second pair of glasses, extra contact lens supplies, and elective dental work like sealants or fluoride treatments all qualify. So do routine cleanings, exams, and preventive care visits you may have been putting off.
Dental care that qualifies includes cleanings, fillings, crowns, extractions, dentures, braces, and X-rays. Teeth whitening does not. On the vision side, eye exams, prescription eyeglasses, contact lenses and supplies, and corrective surgery such as LASIK are eligible. General medical expenses like doctor visit co-pays, hospital deductibles, and prescription drugs cannot come out of an LPFSA. Those have to be paid through your HSA, your HDHP coverage, or out of pocket.
Because of the pre-funding rule, your full annual election is available on the first day of the plan year even if you have not yet contributed the full amount through payroll. If you know you have a balance you cannot spend and no rollover, front-loading a large qualifying expense before year-end is often the cleanest solution.
Estimating Contributions to Avoid Forfeiture
The single most common mistake with any FSA is contributing more than you spend and losing the excess. The LPFSA’s restricted categories make estimating easier than it is with a general-purpose FSA. Add up your predictable annual costs: two dental cleanings, an eye exam, contact lens supplies, and any dental work your dentist has already flagged. Get an estimate from your provider before open enrollment if a larger procedure is on the horizon.
If your plan offers the $680 rollover, a modest buffer above your estimate is reasonable because the carryover protects you from losing that cushion. If your plan offers only a grace period, or nothing at all, contribute closer to what you know you will spend. The $3,400 maximum is a ceiling, not a target.
