If you have heard about a limited-purpose FSA and wondered how it differs from a regular FSA, you are not alone. The term limited FSA eligible items refers to the restricted set of expenses that a limited-purpose Flexible Spending Account (LPFSA) can cover. Unlike a general-purpose healthcare FSA that covers virtually all medical expenses, an LPFSA is designed specifically for dental and vision costs, and it exists primarily to work alongside a health savings account. This article is general information, not tax advice.
Understanding what an LPFSA covers, and why it matters, is essential for anyone who wants to maximize their tax-advantaged healthcare spending without sacrificing HSA eligibility. The LPFSA is one of the few ways to stack two tax-advantaged accounts in the same year.
What Is a Limited-Purpose FSA?
A limited-purpose FSA, also called an LPFSA, is a type of Flexible Spending Account that restricts eligible expenses to dental and vision care only. It follows the same basic mechanics as a regular FSA: you contribute pre-tax dollars through payroll deductions, and you use those funds to pay for eligible expenses throughout the plan year. Contributing pre-tax lowers your taxable income, which is where the savings come from. For 2026, the IRS health FSA contribution limit — which also applies to an LPFSA — is $3,400 per employee (up from $3,300 in 2025); confirm the current figure with your plan, since the IRS sets it each year.
The critical difference is why the LPFSA exists. A general-purpose healthcare FSA makes you ineligible to contribute to an HSA, because both accounts cover the same broad range of medical expenses and the IRS does not allow that kind of overlapping “first-dollar” coverage. An LPFSA solves this by limiting its scope to only dental and vision, which allows you to keep your HSA eligibility while still getting additional pre-tax savings. For more on how FSAs work, see our FSA guide.
LPFSA Eligible Expenses: Dental
The dental portion of limited FSA eligible items covers a comprehensive range of dental services and products. Preventive care — including cleanings, exams, X-rays, and fluoride treatments — qualifies. Restorative work including fillings, crowns, bridges, inlays, and onlays is covered. Root canal therapy, tooth extractions, and periodontal (gum disease) treatments are eligible.
Major dental work also qualifies under an LPFSA. Dental implants, dentures, partial dentures, and orthodontic treatment — including braces and clear aligners such as Invisalign — are covered. Sedation and anesthesia used during a covered dental procedure are eligible. Prescription dental products, such as prescription-strength fluoride toothpaste, are covered as well. As a general rule, any dental expense that would qualify as a medical expense under a regular FSA also qualifies under an LPFSA, because the underlying IRS standard (from Publication 502) is the same.
LPFSA Eligible Expenses: Vision
The vision category covers eye exams, prescription eyeglasses (frames and lenses), prescription sunglasses, contact lenses and contact lens solution, and laser vision correction such as LASIK and PRK. Reading glasses, even without a prescription, are generally eligible. Eye drops for dry eyes or allergies typically qualify as over-the-counter medications when they treat a vision-related condition, though rules on OTC products can vary by plan.
Vision expenses can add up quickly. A pair of prescription glasses with progressive lenses can easily run $300 to $600. Contact lenses can cost $200 to $500 or more per year depending on the type. LASIK often averages roughly $2,000 to $3,000 per eye, though prices vary widely by provider and region. Using LPFSA funds for these expenses provides meaningful tax savings, especially on the higher-ticket items — treat these price ranges as ballpark estimates and confirm your own costs.
What an LPFSA Does Not Cover
Any medical expense outside of dental and vision is excluded from an LPFSA. That means no doctor-visit copays, no general prescription medications (unless dental- or vision-related), no hospital costs, no mental health services, no physical therapy, and no over-the-counter medications (unless they are for a dental or vision condition). These expenses should be paid through your HSA or out of pocket.
Personal-care items that are dental- or vision-adjacent but do not count as medical expenses are also excluded. Regular toothbrushes, non-prescription sunglasses, and cosmetic dental work like teeth whitening are not eligible under an LPFSA, just as they would not be under a regular FSA. When you are unsure whether something counts as dental or vision care, check your plan’s eligible-expense list before you buy.
The LPFSA + HSA Strategy
The primary value of an LPFSA is its compatibility with an HSA. Here is why the combination matters. Your HSA provides a triple tax advantage: pre-tax contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses. Many financial advisors recommend treating your HSA as a long-term investment vehicle rather than spending it on current expenses.
By using an LPFSA for dental and vision expenses, you redirect those predictable costs away from your HSA, allowing your HSA balance to keep growing and compounding over time. Dental and vision expenses tend to be recurring and easy to estimate, which makes them a good fit for an LPFSA’s use-it-or-lose-it structure. Meanwhile, your HSA accumulates for larger medical expenses, retirement healthcare costs, or investment growth. Learn more about how your HSA works alongside this strategy.
LPFSA vs Regular FSA
If you do not have an HSA-eligible high-deductible health plan, you generally do not need an LPFSA — a regular healthcare FSA covers dental, vision, and all other eligible medical expenses. The LPFSA only makes sense when paired with an HSA, because the limited scope is precisely the trade-off that preserves your HSA eligibility.
Some employers allow an LPFSA to convert to a general-purpose FSA after the plan’s deductible has been met. This is called a “post-deductible FSA,” and it expands the eligible-expense list once you have spent enough on medical care to meet your insurance deductible. Not all employers offer this feature, so check your plan documents for details.
How to Decide Your LPFSA Contribution
Estimating your LPFSA election is more straightforward than a regular FSA because you are only projecting dental and vision costs. Add up your expected dental expenses for the year: two cleanings, any planned procedures, and orthodontic payments if applicable. Then add your vision expenses: an annual eye exam, new glasses or contact lenses, and any planned procedures such as LASIK.
Be conservative to avoid forfeiting unused funds under the use-it-or-lose-it rule. If your employer offers a grace period or a carryover provision for the LPFSA, factor that flexibility into your estimate. A good rule of thumb is to cover your known recurring expenses (two cleanings, an annual eye exam, a contact-lens supply) as a baseline, then add only planned procedures that are already scheduled or highly likely. Because the annual limit and any carryover amount are set by the IRS and your employer, verify both with your plan administrator before you enroll.
Frequently Asked Questions
Can I have both an LPFSA and an HSA?
Yes. That is the entire purpose of an LPFSA. It is specifically designed to be compatible with an HSA by limiting eligible expenses to dental and vision only. This lets you get additional pre-tax savings on dental and vision costs while maintaining your HSA eligibility and contributions.
What is the contribution limit for an LPFSA?
For 2026, the LPFSA contribution limit is $3,400, the same as a regular healthcare FSA. This is a per-employee limit. If both you and your spouse have access to LPFSAs through your respective employers, each of you can generally contribute up to the limit. Because the IRS adjusts this figure annually, confirm the current amount with your plan.
Do LPFSA funds roll over?
Like regular FSAs, LPFSA funds are subject to the use-it-or-lose-it rule. Your employer may offer a grace period or a carryover provision, but this varies by plan. Some employers are more willing to offer these provisions for LPFSAs, since the limited scope can make it harder to spend down the balance than with a general-purpose FSA.
Can I use my LPFSA for cosmetic dental work?
No. Purely cosmetic procedures like teeth whitening and cosmetic veneers are not eligible under any type of FSA, including an LPFSA. Only dental care that treats or prevents dental disease qualifies. Restorative work that also has a cosmetic benefit, such as a crown on a visible tooth, generally qualifies because its primary purpose is functional.
Is an LPFSA the same as a “limited-purpose FSA” or “LPFSA eligible expenses” list?
Yes. “Limited FSA eligible items,” “limited-purpose FSA eligible expenses,” and “LPFSA eligible expenses” all describe the same thing: the dental and vision expenses an LPFSA can cover. The exact list can vary slightly by plan, so your administrator’s eligible-expense list is the final word.
The Bottom Line
A limited-purpose FSA covers dental and vision expenses exclusively, and its value lies in its ability to coexist with an HSA. Understanding limited FSA eligible items helps you plan your contributions accurately and coordinate your benefits for maximum tax savings. If you have an HSA and your employer offers an LPFSA, enrolling in both is often the right move — it protects your HSA balance for growth while covering predictable dental and vision costs with additional pre-tax dollars. Just confirm the current limits and eligible-expense list with your plan before you enroll.
