You can have both an HSA and FSA, but only under specific circumstances, and the rules depend on which type of FSA you hold
The short answer is yes — but with a major catch. You can own both a Health Savings Account (HSA) and a Flexible Spending Account (FSA) at the same time, but only if your FSA is a Limited-Purpose FSA or a Dependent Care FSA. If you have a standard medical FSA, you cannot contribute to an HSA in the same year. The IRS treats these accounts as incompatible for tax purposes when both cover the same types of expenses.
The reason for this rule comes down to how the accounts are taxed. An HSA requires you to be enrolled in a High Deductible Health Plan (HDHP), and the IRS does not allow you to have other first-dollar coverage — coverage that pays before you meet your deductible. A standard FSA is first-dollar coverage, which disqualifies you from HSA contributions that same year. A Limited-Purpose FSA, by contrast, only covers dental and vision expenses (or only dental, or only vision), so it does not conflict with HDHP rules.
Key Takeaways
- A standard medical FSA and an HSA cannot coexist in the same tax year because the FSA is considered first-dollar coverage that violates HDHP requirements.
- A Limited-Purpose FSA (covering only dental and vision) can be held alongside an HSA because it does not conflict with HDHP rules.
- A Dependent Care FSA, which covers childcare and adult day care costs, can always be held with an HSA because it covers different expense categories entirely.
- If you have a standard FSA and want to switch to an HSA, you must wait until the next plan year or experience a may have access to life event to change your coverage.
How a Limited-Purpose FSA Works With an HSA
A Limited-Purpose FSA is designed specifically to work alongside an HSA. It covers only dental, vision, and hearing expenses — categories that an HSA can also cover, but the FSA lets you use pre-tax dollars for them without reducing your HSA contribution room.
The contribution limits are separate. In 2024, you can contribute up to $4,150 to an HSA (individual coverage) or $8,300 (family coverage), and separately contribute up to $3,300 to a Limited-Purpose FSA. The FSA money does not count against your HSA limit. You use the FSA for predictable dental and vision costs — cleanings, exams, glasses, contact lenses — and keep your HSA for medical expenses or to build long-term savings.
One practical advantage: a Limited-Purpose FSA has a "use-it-or-lose-it" rule that typically allows you to carry over up to $640 of unused funds into the next year (or your employer may offer a two-month grace period instead). An HSA has no such restriction — unused money rolls forward indefinitely and grows tax-free, making it more flexible for long-term health savings.
Dependent Care FSA and HSA: No Conflict
A Dependent Care FSA covers childcare and adult day care expenses, which are completely separate from medical expenses. Because it does not overlap with what an HSA covers, you can hold both accounts in the same year without any IRS restrictions.
The contribution limit for a Dependent Care FSA is $5,000 per year for a single filer or married couple filing jointly (or $2,500 if married filing separately). This limit is independent of your HSA contribution limit. Many employers offer all three accounts — an HSA, a Limited-Purpose FSA, and a Dependent Care FSA — and employees can contribute to all three simultaneously.
What Happens If You Have a Standard FSA and Want an HSA
If you currently have a standard medical FSA, you cannot contribute to an HSA during the same plan year. However, you have options for the future. Most employers allow plan changes during open enrollment, which typically occurs once per year in the fall. At that time, you can drop your standard FSA and enroll in an HDHP, which makes you HSA-may be able to access starting January 1 of the next year.
If you experience a may have access to life event — marriage, divorce, birth of a child, loss of other health coverage, or a significant change in your employer's plan — you may be able to make changes outside of open enrollment. The timing matters: if you drop your FSA mid-year due to a may have access to event, you generally cannot contribute to an HSA until the next plan year begins.
One important detail: if you have money left in your standard FSA at the end of the year, you lose it (with limited exceptions for carryover or grace periods that your employer may offer). Plan your FSA spending carefully before switching to an HSA, because you cannot transfer FSA funds to an HSA.
The HDHP Requirement for HSA may be able to access
To contribute to an HSA, you must be enrolled in an HDHP. In 2024, an HDHP has a minimum deductible of $1,600 for individual coverage or $3,200 for family coverage. You also cannot have other health coverage that is not an HDHP — with one exception: a Limited-Purpose FSA is allowed because it does not cover medical expenses.
This is why the standard FSA rule exists. A standard FSA pays for doctor visits, prescriptions, and other medical care before you meet your deductible, which means you do not have "high deductible" coverage anymore. The IRS sees this as incompatible with HSA rules. A Limited-Purpose FSA, by contrast, only covers dental and vision, so it does not interfere with your HDHP's medical deductible structure.
Contribution Limits and Coordination
When you have an HSA and a Limited-Purpose FSA, the contribution limits are tracked separately and do not reduce each other. Your employer withholds contributions to each account from your paycheck before taxes are calculated, so both reduce your taxable income for the year.
| Account Type | 2024 Individual Limit | 2024 Family Limit | Can Coexist With HSA? |
|---|---|---|---|
| HSA | $4,150 | $8,300 | — |
| Limited-Purpose FSA | $3,300 | $3,300 | Yes |
| Standard Medical FSA | $3,300 | $3,300 | No |
| Dependent Care FSA | $5,000 | $5,000 | Yes |
If you hold both an HSA and a Limited-Purpose FSA, you can use either account to pay for dental and vision expenses. Some people use the FSA first (since it has a use-it-or-lose-it important date) and save HSA funds for other medical expenses or long-term growth. Others do the reverse. The choice depends on your expected expenses and how much you want to keep in your HSA for future years.
Frequently Asked Questions
If I switch from a standard FSA to an HSA mid-year, can I get my unused FSA money back?
No. FSA funds are forfeited if unused by the end of the plan year (or the grace period, if your employer offers one). You cannot transfer FSA money to an HSA or receive a refund. This is why it is important to spend down your FSA before dropping it for an HDHP.
Can I have an HSA with a standard FSA if my employer offers both?
No. The IRS prohibits this combination in the same tax year. If your employer offers both, you must choose one or the other. If you want an HSA, you must enroll in an HDHP and not contribute to a standard FSA that same year.
What if my spouse has an HSA and I have a standard FSA?
Each person's accounts are separate. Your spouse can have an HSA while you have a standard FSA, as long as you are not on the same HDHP. If you are both on the same family HDHP, neither of you can contribute to a standard FSA — only a Limited-Purpose FSA or Dependent Care FSA.
Do I have to use my Limited-Purpose FSA before my HSA?
No. You can use either account to pay for dental and vision expenses. Many people use the FSA first because it has a use-it-or-lose-it rule, but you can use them in any order. Just keep receipts to show which account paid for which expense.
Can I roll over unused Limited-Purpose FSA money to next year?
Most Limited-Purpose FSAs allow a carryover of up to $640 into the next year, or your employer may offer a two-month grace period to spend the money instead. Check your plan documents to see which option your employer provides. Unlike an HSA, any amount over the carryover limit is forfeited.
