A limited purpose FSA, restricted to dental and vision expenses, is the narrow exception that lets both accounts coexist.\n\n## What changed in 2026\n\n- **Annual FSA contribution limits are adjusted for inflation each year**, and the limited purpose version uses the same cap as a general FSA — verify the current-year number with your employer's plan documents.\n- **More employers are offering LPFSAs specifically to make HDHP-plus-HSA enrollment more attractive**, since it lets employees keep pre-tax dental and vision budgeting without giving up the HSA.\n- **Some plans now extend limited purpose coverage to preventive care more broadly**, not just dental and vision, depending on how the employer's plan document is written — check yours rather than assuming a standard scope.\n\n## What it actually covers\n\nDental cleanings, fillings, orthodontia, and most dental procedures; eyeglasses, contact lenses, eye exams, and vision correction surgery. It does not cover general medical copays, prescriptions unrelated to dental or vision, or over-the-counter medication the way a general FSA or your [HSA](/blog/hsa-eligible-expenses-2026) would.\n\n## Why pair it with an HSA instead of just using the HSA\n\nYou could pay dental and vision costs directly from your HSA. The advantage of running them through a limited purpose FSA instead is that the FSA money is \"spend it or (mostly) lose it,\" which nudges you to actually use it for known, predictable costs like a routine cleaning or new glasses — while your HSA balance keeps growing untouched for larger, less predictable medical costs or long-term investing.\n\n| Account | Covers | Combine with HSA? | Rollover |\n|---|---|---|---|\n| General purpose FSA | Broad medical, dental, vision | No | Limited grace period/carryover |\n| Limited purpose FSA | Dental and vision only | Yes | Limited grace period/carryover |\n| Dependent care FSA | Childcare, eldercare | Yes | Limited grace period/carryover |\n| HSA | Broad medical, dental, vision | — | Full, indefinite |\n\n## Planning around use-it-or-lose-it\n\nUnlike an HSA, FSA funds are generally forfeited if unused by the plan year deadline, though many employers allow either a short grace period or a small carryover into the next year — not both. Estimate known dental and vision costs (a cleaning, a set of contacts) conservatively rather than maximizing the contribution on a guess.\n\n## Enrolling and changing your election\n\nYou elect an amount during your employer's open enrollment, and that election is generally locked in for the plan year unless you have a qualifying life event — a new baby, a marriage, or a change in your spouse's coverage, for example. Because the limited purpose FSA only exists to preserve HSA eligibility, double-check during enrollment that you are actually being offered the limited purpose version and not a general purpose FSA by mistake, since payroll systems do not always label the two clearly and enrolling in the wrong one can retroactively disqualify your HSA contributions for the year.\n\n## FAQ\n\n**Can I switch from a limited purpose FSA to a general FSA mid-year?**\nOnly with a qualifying life event, the same rule that governs most benefit elections outside open enrollment.\n\n**Does a limited purpose FSA affect my HSA contribution limit?**\nNo, the two are independent. You can contribute the maximum to each simultaneously, up to their separate annual limits.\n\n**What happens to unused funds if I leave my job?**\nDepends on your plan — some allow a short runout period to submit claims for expenses incurred before your last day, but the balance itself is generally forfeited.\n\n**Is a limited purpose FSA worth it if I rarely have dental or vision costs?**\nProbably not — the pre-tax savings only help if you actually spend the funds, and unused balances are largely forfeited.\n\nThis is general information, not tax or insurance advice — confirm your specific plan's covered expenses and deadlines with your employer's benefits administrator.\n\n## Where to go next\n\nCompare it against the childcare-focused account in [dependent care FSA explained](/blog/dependent-care-fsa-explained-2026), see the full [HSA eligible expenses list](/blog/hsa-eligible-expenses-2026), and read [HSA vs FSA](/blog/hsa-vs-fsa-2026) for the bigger-picture comparison.","hue":240,"metaTitle":"Limited Purpose FSA 2026: How It Works With an HSA","metaDescription":"What a limited purpose FSA covers in 2026, why it can be combined with an HSA when a regular FSA cannot, and how the pre-tax savings actually work.","keywords":["limited purpose fsa 2026","lpfsa explained","limited purpose fsa vs hsa","dental vision fsa","can i have hsa and fsa together","limited purpose flexible spending account","lpfsa eligible expenses","hsa compatible fsa"],"tldr":["**A limited purpose FSA only covers dental and vision** — it exists specifically so HSA holders do not lose HSA eligibility.","**You can hold one alongside an HSA legally** — a regular general-purpose FSA cannot be combined with an HSA under IRS rules.","**It still uses pre-tax payroll dollars** — the tax savings work exactly like a general FSA, just on a narrower category of expenses.","**Use-it-or-lose-it rules still apply**, though many plans allow a grace period or a small carryover — check your specific plan document.","**Skip:** assuming it covers the same things as a regular FSA — medical copays and prescriptions are not eligible under a limited purpose LPFSA."],"readTime":"3 min read","wordCount":719},"related":[{"slug":"how-to-use-an-fsa-2026","title":"How to use an FSA in 2026: contribute, spend, and avoid forfeiting money","excerpt":"A flexible spending account can save you hundreds in taxes on healthcare costs, but the use-it-or-lose-it rule catches people every year.
