LPFSA: Limited Purpose FSA Explained (2026)

The Account That Lets You Keep Your HSA and Get More Coverage

If you have a Health Savings Account and wish you could set aside even more pre-tax money for healthcare, the LPFSA — Limited Purpose Flexible Spending Account — is built for exactly that scenario. Most people do not realize they can pair an FSA with an HSA, because a general-purpose FSA disqualifies you from HSA contributions. The LPFSA solves that conflict by restricting coverage to dental and vision expenses only, preserving your HSA eligibility while giving you a second tax-advantaged account.

For 2026, you can contribute up to about $3,400 to an LPFSA (verify the current figure against IRS guidance), in addition to your HSA contributions of $4,400 for individual coverage or $8,750 for family coverage. That is a combined pre-tax allocation of roughly $12,150 for a family — a powerful tool for reducing your healthcare tax burden. Because these limits are adjusted annually and rules can vary by plan, confirm the current numbers with your benefits administrator or a tax advisor before you rely on them.

How an LPFSA Works

An LPFSA operates like a standard healthcare FSA in most respects. You elect a contribution amount during open enrollment, your employer deducts it from your paychecks pre-tax, and you spend the funds on eligible expenses throughout the plan year. The key difference is scope: while a general FSA covers all qualified medical expenses, the LPFSA is limited to dental and vision expenses. That single restriction is what keeps you eligible to contribute to an HSA at the same time.

Your full annual election is available on the first day of the plan year under the uniform coverage rule. If you elect $2,000 and need $2,000 worth of dental work in January, you can submit the claim in full — even if only one or two payroll deductions have occurred. This is one of the FSA family’s best features and a meaningful difference from an HSA, which you can only spend once the money is actually in the account.

Access your funds through an LPFSA debit card or by submitting manual reimbursement claims. Most administrators automatically restrict card transactions to dental and vision merchants and product codes, and they may ask you to substantiate a purchase with an itemized receipt.

What Does an LPFSA Cover?

The eligible expense list for an LPFSA is narrower than a general FSA but still covers a significant range of dental and vision costs. IRS Publication 502 is the reference for what counts as a qualified dental or vision expense.

Dental Expenses

Exams, cleanings, and X-rays. Fillings, crowns, bridges, and inlays. Root canals and extractions. Orthodontics — braces, clear aligners, retainers. Dentures and denture supplies. Periodontal treatment — scaling, root planing, gum surgery. Night guards for bruxism. Dental sealants and fluoride treatments. Note that purely cosmetic work, such as teeth whitening, is generally not eligible.

Vision Expenses

Eye exams. Prescription eyeglasses (frames and lenses). Prescription sunglasses. Contact lenses (daily, biweekly, monthly). Contact lens solution and accessories. LASIK and PRK surgery. Reading glasses (including non-prescription readers).

Medical expenses outside of dental and vision — such as doctor visits, prescription medications, or hospital bills — are not LPFSA eligible. Those expenses are reserved for your HSA. For a full dental guide, see our article on using your HSA for dental care.

Why Pair an LPFSA With Your HSA?

The strategic value of the LPFSA lies in how it complements your HSA. By using LPFSA funds for dental and vision costs, you free up your HSA dollars for other medical expenses — or better yet, you let your HSA balance grow untouched for long-term investment.

Consider this example: you have a $500 dental bill and a $300 pair of prescription glasses this year. Without an LPFSA, you would use $800 from your HSA. With an LPFSA, you cover both expenses from the limited-purpose account and keep $800 in your HSA, where it can grow tax-free through investments. Over 20 years, that $800 invested at a hypothetical 7 percent annual return becomes roughly $3,100 — all because you used the right account for the right expense. (Investment returns are not guaranteed; this is an illustration, not a projection.)

Our HSA benefits guide explains why the long-term growth potential of the HSA makes it worth preserving.

LPFSA Contribution Limits for 2026

The LPFSA shares the same contribution limit as the general healthcare FSA: about $3,400 for 2026 (verify against current IRS guidance, as the figure is set by annual inflation adjustment). This is a per-employee limit. If both spouses have access to LPFSAs through their own employers, each can generally contribute up to the maximum.

Your LPFSA contribution is separate from your HSA contribution. For 2026, this means you could contribute up to about $3,400 to your LPFSA plus $4,400 (individual) or $8,750 (family) to your HSA, and add the $1,000 HSA catch-up contribution if you are 55 or older. Employer contributions to the HSA count toward the HSA limit but do not affect your LPFSA cap. Always confirm your own limits with your plan administrator, because plan-specific rules can apply.

Use-It-or-Lose-It: What Happens to Unspent LPFSA Funds

Like a standard FSA, the LPFSA is subject to the use-it-or-lose-it rule. Funds not spent by the end of the plan year are forfeited, unless your employer offers a grace period (up to 2.5 months into the next plan year) or a carryover (about $680 for 2026, verify the current amount). Employers can offer one of these options but not both, and not every employer provides either, so check your plan documents.

To avoid forfeiting funds, estimate your dental and vision spending carefully before electing a contribution. Review last year’s costs — dental copays, cleanings, glasses, contact lenses — and use that as your baseline. If you tend to spend less than $1,000 a year on dental and vision combined, a modest LPFSA election may be more appropriate than maxing out.

LPFSA vs. General FSA vs. HSA

Understanding where the LPFSA fits relative to other accounts helps you make the right enrollment decisions.

A general healthcare FSA covers all qualified medical expenses and is available with most employer health plans, but it disqualifies you from contributing to an HSA. An LPFSA covers only dental and vision expenses and is specifically designed to work alongside an HSA. An HSA covers all qualified medical expenses, requires enrollment in a qualifying high-deductible health plan (HDHP), and offers permanent rollover and investment capability.

If your employer offers a qualifying HDHP with HSA eligibility, the optimal pairing is often HSA plus LPFSA. If your employer offers only a traditional health plan, the general FSA is your tax-advantaged option. For a deeper comparison, read our HSA and FSA guide.

How to Enroll in an LPFSA

Not every employer offers an LPFSA, even if they offer an HSA. During your open enrollment period, check whether your benefits package includes a Limited Purpose FSA. It may be listed as “LPFSA,” “Limited FSA,” “Dental and Vision FSA,” or a similar name. If you do not see it, ask your HR department — some employers add the option by request or include it as an opt-in benefit.

Once enrolled, set your contribution amount based on your anticipated dental and vision spending. Remember that you generally cannot change your election mid-year unless you experience a qualifying life event, such as marriage, the birth of a child, or a change in employment.

Frequently Asked Questions

Can I use my LPFSA for medical expenses other than dental and vision?

No. The LPFSA is restricted to dental and vision expenses only. Using it for other medical costs would jeopardize your HSA eligibility. Use your HSA for all non-dental, non-vision medical expenses. (One exception some plans offer is a “post-deductible” feature; see the question below.)

What happens to my LPFSA if I leave my job?

Your LPFSA generally ends when your employment ends. You can usually be reimbursed for eligible dental and vision expenses incurred before your termination date, but you lose access to unspent funds after that (COBRA continuation of an FSA is sometimes available — ask your administrator).

Can my LPFSA cover my family’s dental and vision expenses?

Yes. You can use LPFSA funds for dental and vision expenses incurred by your spouse and tax dependents. Keep separate documentation for each family member in case a claim is audited.

Does the LPFSA convert to a general FSA after I meet my deductible?

Some employers offer a “post-deductible” feature that lets the account also reimburse general medical expenses after you meet your HDHP deductible. This is a specific plan design, not a standard LPFSA. Check your plan documents to see which type your employer offers.

Can I have both an LPFSA and a Dependent Care FSA?

Yes. The LPFSA, Dependent Care FSA, and HSA are all separate accounts with separate limits. You can contribute to all three simultaneously if your employer offers them. See our guide on dependent care FSA eligible expenses for details on the DCFSA.

Add the LPFSA to Your Benefits Strategy

The LPFSA is one of the most underused benefits in the employer toolkit. If you already have an HSA, adding a Limited Purpose FSA gives you a dedicated pre-tax fund for dental and vision expenses while protecting your HSA balance for investment growth and future medical needs. During your next open enrollment, check whether your employer offers this option, estimate your dental and vision costs, and set a contribution that matches your expected spending. Confirm the current limits and rules with your benefits administrator or a tax advisor, and see IRS Publication 969 for the governing federal rules.
