A limited purpose FSA (LPFSA) is a tax-advantaged flexible spending account that allows employees to set aside pre-tax dollars exclusively for qualifying dental and vision care expenses. Unlike a general-purpose FSA, which covers a broad range of medical costs, the LPFSA is intentionally restricted to preserve an individual's eligibility to contribute to a Health Savings Account (HSA).
The LPFSA operates on a use-it-or-lose-it basis, though some plans offer a grace period or carryover option. Employees elect a contribution amount during open enrollment, and funds are deducted from each paycheck throughout the year. For example, an employee contributing $1,200 annually can use those funds for orthodontic work, prescription eyeglasses, contact lenses, or routine eye exams. Employers often provide debit cards linked to the account for convenient payment at the point of service, and employees submit receipts for verification and reimbursement.
Limited purpose FSAs matter because they enable employees to maximize tax savings while maintaining HSA eligibility, a critical consideration for high-deductible health plan participants. By segregating dental and vision expenses into a separate account, workers can contribute the full HSA limit and still enjoy pre-tax benefits for routine care. This dual-account strategy can save families hundreds of dollars annually in taxes. For employers, offering an LPFSA enhances benefits competitiveness and supports financial wellness, helping attract and retain talent in markets where comprehensive health benefits are a key differentiator.
- Verify HSA compatibility: Confirm employees are enrolled in a qualifying high-deductible health plan and contributing to an HSA, as the LPFSA is designed to complement, not replace, HSA eligibility.
- Estimate annual dental and vision costs: Review past expenses for exams, cleanings, fillings, glasses, and contacts to determine an appropriate contribution amount that avoids forfeiting unused funds at year-end.
- Enroll during open enrollment: Select the LPFSA option and specify the annual election amount; funds will be deducted pre-tax from each paycheck and made available according to plan rules.
- Submit claims with documentation: Pay providers using the FSA debit card or out-of-pocket, then file claims with itemized receipts showing the service date, provider, and expense type to receive reimbursement.
Key Statistics & Benchmarks
- IRS 2024 contribution limit is $3,200 — maximum annual election for limited purpose FSAs.
- Dental and vision expenses only — orthodontia, exams, lenses, and frames qualify under LPFSA rules.
- Use-it-or-lose-it applies — unused funds typically forfeit unless a grace period or carryover is offered.
- Pre-tax savings average 30% — combined federal, state, and FICA tax reduction on contributions.
Common Mistakes to Avoid
- Over-contributing: Estimate conservatively to avoid forfeiting unused funds at year-end; review past dental and vision spending patterns.
- Confusing with general FSA: Remember LPFSAs cover only dental and vision, not medical expenses, to preserve HSA eligibility.
- Missing claim deadlines: Submit receipts promptly and track plan runout periods to ensure reimbursement before the deadline expires.
Frequently Asked Questions
What is the difference between a limited purpose FSA and a regular FSA?
A limited purpose FSA covers only dental and vision expenses, while a regular FSA covers a broader range of medical, dental, and vision costs. The LPFSA is specifically designed for employees who contribute to a Health Savings Account (HSA), as IRS rules prohibit HSA contributions if you have a general-purpose FSA. Choosing an LPFSA allows you to maximize both accounts simultaneously.
How much can I contribute to a limited purpose FSA in 2024?
The IRS sets the annual contribution limit for limited purpose FSAs at $3,200 for 2024. This amount is per individual, not per household, so if both spouses have access to an LPFSA through their employers, each can contribute up to the maximum. Contributions are made pre-tax through payroll deductions, reducing your taxable income and providing immediate savings on federal, state, and FICA taxes.
Can I have both a limited purpose FSA and an HSA?
Yes, you can have both a limited purpose FSA and an HSA simultaneously, which is the primary reason LPFSAs exist. To maintain HSA eligibility, you must be enrolled in a high-deductible health plan and cannot have a general-purpose FSA. The LPFSA's restriction to dental and vision expenses ensures compliance with IRS rules, allowing you to enjoy the tax benefits of both accounts.
What happens to unused limited purpose FSA funds at year-end?
Unused limited purpose FSA funds are typically forfeited under the use-it-or-lose-it rule, though some employers offer a grace period of up to 2.5 months or allow a carryover of up to $640 into the next plan year. Check your plan documents to understand which option applies. To minimize forfeiture risk, estimate your annual dental and vision expenses conservatively and schedule eligible services before the plan year ends.
