A limited purpose FSA lets you set aside pretax money for dental and vision costs only, not medical expenses

A limited purpose flexible spending account (LPFSA) is a workplace savings plan where you contribute pretax dollars to pay for dental work, vision care, and hearing aids. It does not cover doctor visits, prescriptions, or hospital care. The money comes out of your paycheck before taxes are calculated, which lowers your taxable income for the year.

The main reason to choose an LPFSA instead of a regular FSA is that it works alongside a health savings account (HSA). If you have an HSA and a high-deductible health plan, you cannot contribute to a regular FSA in the same year—the IRS does not allow it. An LPFSA sidesteps that rule because it covers only dental and vision, leaving your HSA available for medical expenses.

You set a contribution limit each year during open enrollment, and that money sits in the account until you use it. Unlike an HSA, an LPFSA does not roll over unused funds to the next year. Money left in the account at the end of the plan year is forfeited, though most plans give you a grace period of up to 2.5 months to spend it down.

Key Takeaways

  • An LPFSA covers only dental, vision, and hearing aid costs, not medical care, and the money must come from pretax payroll deductions.
  • You can have an LPFSA and an HSA at the same time, which is not possible with a regular FSA.
  • Unused money in an LPFSA does not carry over to the next year and will be lost unless you spend it during the grace period.
  • You must submit receipts or explanation of benefits to prove the expense is may be able to access before the plan reimburses you.

What an LPFSA actually covers

may be able to access expenses under an LPFSA are limited to three categories: dental, vision, and hearing aids. Dental includes cleanings, fillings, root canals, crowns, orthodontia, and dentures. Vision covers eye exams, glasses, contact lenses, and lens solutions. Hearing aids and related repairs and batteries also may have access to.

Expenses that do not may have access to include general medical care (doctor visits, lab work, X-rays), prescriptions, over-the-counter medications, and cosmetic procedures. Teeth whitening is cosmetic and does not may have access to. Laser eye surgery (LASIK) is often excluded, though some plans cover it—check your plan document. Sunglasses, even with a prescription, do not may have access to.

You pay out of pocket at the time of service, then request reimbursement from the plan. You will need to submit a receipt or an explanation of benefits showing the date, the provider, the service, and the amount paid. The plan processes the claim and deposits the reimbursement into your bank account or issues a debit card.

How contribution limits and the use-it-or-lose-it rule work

Each year, you choose how much to contribute to your LPFSA, up to a limit set by the IRS. That limit changes annually; in recent years it has been around $3,200, but confirm the current year's limit with your employer's benefits office. The money is deducted from your paycheck in equal installments throughout the year.

Unlike an HSA, an LPFSA operates under a strict use-it-or-lose-it rule. Any money you do not spend by the end of the plan year is forfeited and goes back to your employer. Most plans offer a grace period—usually 2.5 months into the next year—during which you can still submit claims for expenses incurred in the prior year. After that window closes, the money is gone.

This means you need to estimate your dental and vision costs carefully. If you know you need a crown or new glasses, schedule the work before the plan year ends or during the grace period. If you overestimate and have money left over, you lose it. If you underestimate, you pay out of pocket for the rest.

Why you might choose an LPFSA over a regular FSA

The main reason is compatibility with an HSA. If you are enrolled in a high-deductible health plan and have an HSA, you cannot open a regular FSA in the same year. The IRS treats a regular FSA as a low-deductible plan, which disqualifies you from HSA contributions. An LPFSA does not trigger this conflict because it covers only dental and vision, not medical care.

This matters because an HSA is often the better deal: it rolls over year to year, you own the money even if you leave your job, and you can invest it. A regular FSA is use-it-or-lose-it and belongs to your employer. If you have both an HSA and an LPFSA, you can save pretax money for medical expenses in the HSA and pretax money for dental and vision in the LPFSA.

If you do not have an HSA or a high-deductible plan, a regular FSA usually makes more sense because it covers medical expenses too. Talk to your benefits administrator about which option is available to you.

How to enroll and submit claims

Enrollment happens once a year during your employer's open enrollment period, usually in the fall. You log into your benefits portal, select the LPFSA, and enter the amount you want to contribute for the coming year. The money is deducted from your paycheck in equal portions each pay period.

When you incur a dental or vision expense, pay the provider directly. Then gather your receipt or explanation of benefits and submit it to the plan administrator through their website, app, or by mail. Include the date of service, the provider's name, the type of service, and the amount paid. The plan reviews the claim to confirm it is may be able to access and reimburses you within a few business days.

Some employers issue a debit card linked to the LPFSA, which you can use at participating providers without submitting a claim afterward. If your plan offers this, the card is the fastest way to access your money. If not, keep all receipts and submit them promptly so you do not miss the grace period deadline.

What happens to unused money and the grace period

If you have money left in your LPFSA at the end of the plan year, you do not automatically lose it. Most plans include a grace period—typically 2.5 months into the next calendar year—during which you can submit claims for expenses you incurred in the prior year. For example, if your plan year ends December 31, you can usually submit claims through mid-March for dental or vision work done in December.

After the grace period ends, any remaining balance is forfeited. Your employer keeps the money; it does not roll over to your account, and you cannot carry it forward. This is why it is important to track your spending throughout the year and plan major dental or vision work before the year ends if you have a large balance.

Some employers also offer a carryover option of up to $640 (as of recent years, though this amount can change), which allows you to roll a small amount into the next year. Check your plan document to see if this is available to you.

LPFSA versus HSA versus regular FSA: which is right for you

If you have a high-deductible health plan and an HSA, an LPFSA is the only FSA option available to you. It lets you save pretax money for dental and vision while keeping your HSA intact for medical expenses. If you do not have an HSA, a regular FSA is usually better because it covers medical care, prescriptions, and other health expenses in addition to dental and vision.

An HSA is the most flexible option if you are may be able to access: it rolls over, you own it, and you can invest the balance. But it requires a high-deductible plan, which means you pay more out of pocket for medical care until you hit your deductible. An LPFSA is simpler—it covers only dental and vision—but the money is lost if you do not spend it.

The right choice depends on your health plan, your expected dental and vision costs, and whether you want to save for medical expenses too. Your employer's benefits office can tell you which options are available and help you compare them.

Frequently Asked Questions

Can I use my LPFSA money for my spouse or children?

Yes. Money in your LPFSA can be used to pay for may be able to access dental and vision expenses for you, your spouse, and any dependents you claim on your tax return. You do not need to be the one receiving the service—you just need to be the one paying for it and able to claim the dependent.

What if I leave my job before the year ends?

You lose access to the LPFSA when you leave. You have a limited time (usually 60 days) to submit claims for expenses you incurred while employed, but any unused balance is forfeited. Your new employer may offer an LPFSA or regular FSA, but you cannot transfer the old account balance.

Can I change my contribution amount during the year?

No, unless you have a may have access to life event such as marriage, birth of a child, loss of coverage, or a significant change in your spouse's benefits. Outside of these events, your contribution is locked in for the plan year. Check your plan document or ask your benefits administrator what counts as a may have access to event.

Do I need receipts to get reimbursed?

Yes. You must submit a receipt or explanation of benefits showing the date, provider, service, and amount paid. If you use a debit card linked to the LPFSA, the plan may not require a receipt for every transaction, but you should keep them anyway in case the plan asks for proof later.

What if I submit a claim after the grace period ends?

The plan will deny the claim. Once the grace period closes, you cannot submit claims for prior-year expenses, and any remaining balance is forfeited. Mark the grace period deadline on your calendar and submit all claims before it passes.
