What Is Limited Purpose FSA
A Limited Purpose FSA is a Flexible Spending Account restricted to dental and vision expenses only. It exists specifically to work alongside a Health Savings Account (HSA). Since regular FSAs are incompatible with HSA eligibility under IRS rules, the Limited Purpose FSA lets workers enrolled in HSA-qualified high-deductible health plans still pre-tax their predictable dental and vision costs.
For people navigating government benefits, this matters because FSA funds are separate from Medicaid, SNAP, TANF, and WIC. If you work and have employer coverage, an FSA can stretch your budget by reducing taxable income. The funds don't count toward means-tested program limits because they're pre-tax payroll deductions, not income.
Eligibility and Enrollment
You can only open a Limited Purpose FSA if your employer offers one and you're enrolled in an HSA-qualified health plan (typically a high-deductible plan with an annual deductible of at least $1,550 for individual coverage or $3,100 for family coverage as of 2024). Enrollment happens during your employer's open benefits period, usually once yearly.
Limited Purpose FSAs don't affect SNAP, Medicaid, TANF, or WIC eligibility because the IRS treats FSA contributions as pre-tax deductions, not taxable wages. This is distinct from HSA distributions, which also don't count toward income limits for needs-based programs.
Contribution Limits and Rules
- For 2024, you can contribute up to $3,200 per year to a Limited Purpose FSA (increases to $3,300 in 2025)
- Contributions are deducted from your paycheck before taxes, lowering your taxable income
- You must spend the money within the plan year; unused funds (up to $640 in 2024) roll to the next year if your plan allows it
- Eligible expenses include dental cleanings, fillings, orthodontia, root canals, and vision exams, glasses, and contacts
- Cosmetic dental work and over-the-counter vision products without a prescription don't qualify
How It Works With Government Benefits
If you receive Medicaid or WIC for dental coverage, a Limited Purpose FSA can supplement those benefits. Medicaid covers emergency dental in most states but not routine cleanings for adults. An FSA lets you pay for preventive care with pre-tax dollars, reducing out-of-pocket costs. The same applies to vision: Medicaid covers eye exams but not frames or lenses in many states. An FSA bridges that gap.
SNAP and TANF don't cover dental or vision, so an FSA is purely optional. TANF work requirements might make employer coverage more accessible though. If you work toward TANF employment goals, you may gain access to FSA benefits through that job.
Common Questions
- Does opening a Limited Purpose FSA lower my SNAP or Medicaid benefits? No. FSA contributions are pre-tax, so they don't count as income for eligibility. Your modified adjusted gross income stays lower.
- Can I use a Limited Purpose FSA for prescription glasses? Yes. Exams, frames, contacts, and lenses all qualify. Non-prescription sunglasses do not.
- What happens if I don't spend my FSA balance by year-end? You lose it, unless your employer allows a grace period (up to 2.5 months) or lets you carry over $640. Check your plan documents or ask HR.
