You can have an FSA without health insurance, but only certain types. A Health FSA is almost always locked to enrollment in your employer’s group medical plan, while a Dependent Care FSA and a Limited Purpose FSA are not. If your employer offers them and you are a common-law employee, you can use those accounts whether or not you take the medical coverage.
Why a Health FSA Is Tied to Group Medical Coverage
A Health FSA is set up through a Section 125 cafeteria plan run by your employer; you cannot open one on your own at a bank or brokerage.1Office of the Law Revision Counsel. 26 U.S. Code 125 – Cafeteria Plans The tax code does not literally say uninsured employees cannot have one. The link comes from federal regulations that treat a Health FSA as an “excepted benefit” only if two conditions are met: the employer makes other group health coverage available to the same class of employees, and the maximum annual FSA payout does not exceed two times your salary reduction election, or your election plus $500, whichever is greater.
If a Health FSA fails the excepted-benefit test, usually because no other group health plan is offered, it becomes subject to Affordable Care Act market reform rules on its own. An employer running a non-compliant plan can be hit with an excise tax of $100 per affected employee per day.2eCFR. 26 CFR 54.9831-1 – Special Rules Relating to Group Health Plans That is why virtually every employer requires you to enroll in the group health plan before you can fund a Health FSA. The rule protects the company from penalties. Some employers may permit a Health FSA when you are covered by a spouse’s or parent’s group plan, so if that describes you, ask your benefits administrator before assuming you are shut out.
Dependent Care FSA: No Medical Coverage Needed
A Dependent Care FSA sits in a different part of the tax code, Section 129, and has no legal connection to health insurance.3Office of the Law Revision Counsel. 26 U.S. Code 129 – Dependent Care Assistance Programs If your employer offers one, you can participate even if you decline every medical option on the benefits menu.
The account reimburses care that lets you and your spouse work or look for work. Qualifying dependents are children under age 13 who are your tax dependents, and a spouse or other dependent who cannot care for themselves and lives with you more than half the year. Eligible costs include daycare, preschool, before- and after-school care, day camps, and care for a disabled dependent. Overnight camps and school tuition do not qualify.
Starting in 2026, the maximum annual exclusion is $7,500 for married couples filing jointly, up from the $5,000 cap that had held since 1986. Married filing separately is $3,750.3Office of the Law Revision Counsel. 26 U.S. Code 129 – Dependent Care Assistance Programs For divorced or separated parents, only the custodial parent can use a Dependent Care FSA for the child’s expenses.4Internal Revenue Service. Publication 503, Child and Dependent Care Expenses
Limited Purpose FSA if You Only Have an HDHP
A Limited Purpose FSA, sometimes labeled LEX HCFSA, covers only dental and vision expenses. It exists for workers enrolled in a high-deductible health plan who also contribute to a Health Savings Account. A regular Health FSA would disqualify you from HSA contributions; the Limited Purpose version sidesteps that conflict by narrowing what it pays for.5FSAFEDS. Limited Expense Health Care FSA
Eligible expenses include vision exams, eyeglasses, contact lenses, LASIK, dental cleanings, X-rays, fillings, crowns, and orthodontia. For 2026, the maximum contribution is $3,400, with up to $680 in unused funds carrying over into the next plan year.6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill This account does require an HDHP, so it is not a path for someone with no medical coverage at all. It is a path for someone whose only medical coverage is high-deductible.
If You Drop or Lose Coverage Mid-Year
When you lose your group health plan during the year, whether through a job change, layoff, or dropping the plan, your Health FSA access typically ends on the same date. Expenses incurred after that date are generally not reimbursable, even if you still have a balance. Front-loaded contributions can be stranded.
The Consolidated Omnibus Budget Reconciliation Act can keep the account alive through the end of the plan year. If your employer has 20 or more employees and your FSA is underspent (your contributions to date exceed reimbursements paid), the employer must offer COBRA continuation for the FSA. You would pay one-twelfth of your annual election each month, after tax, plus a 2% administrative fee. Because those payments are no longer pre-tax, COBRA on an FSA rarely pays off unless the unspent balance is large and you expect eligible expenses before year-end. You have 60 days from the loss of coverage or the COBRA notice, whichever is later, to elect. Miss it and any balance is forfeited.
A qualifying life event such as loss of employment, a marriage or divorce, or a change in dependents can also let you stop or change your election outside open enrollment, typically within 30 to 60 days of the event depending on the plan.7FSAFEDS. Qualifying Life Events Quick Reference Guide The change has to be consistent with the event.
Self-Employed and Unemployed Workers
If you are self-employed, a partner in a partnership, or a shareholder owning more than 2% of an S-corporation, no FSA is available to you, health or dependent care. Section 125 cafeteria plans are open only to common-law employees, which excludes independent contractors and business owners.1Office of the Law Revision Counsel. 26 U.S. Code 125 – Cafeteria Plans The IRS has confirmed that 2%-or-greater S-corporation shareholders are not eligible.8Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues Unemployment closes the door for a different reason: an FSA is tied to active payroll. Leave the payroll and contributions stop; the account does not travel to a new job the way a bank balance would.
So the short version. No medical coverage but on your employer’s payroll: a Dependent Care FSA is available if offered, and a Limited Purpose FSA is available if you have an HDHP. A Health FSA, in practice, is not.
