HSA vs LPFSA: What employers need to know

Key takeaways:

A Health Savings Account (HSA) and a Limited Purpose Flexible Spending Account (LPFSA) serve different purposes, but eligible employees can hold both accounts at the same time.
HSAs offer long-term, portable savings for qualified medical expenses, while LPFSAs are restricted to eligible dental and vision expenses and follow use-it-or-lose-it rules.
Offering both account types can help employees better manage out-of-pocket healthcare costs.

Rising premiums and unpredictable out-of-pocket costs push people to look for every available way to stretch their paychecks further. As a benefits leader, you can help by offering the right mix of savings and spending accounts.

Two accounts employers should understand are the Health Savings Account (HSA) and the Limited Purpose Flexible Spending Account (LPFSA). Both help employees pay for healthcare with pre-tax dollars, but they serve distinct purposes.

So, how do they differ? Who qualifies? And how can they work together?

Let’s break down what each account does, how eligibility works, and why offering both may strengthen your benefits strategy.

What is a Health Savings Account?

A Health Savings Account is a tax-advantaged account that helps employees covered by a qualified high-deductible health plan (HDHP) save and pay for eligible medical expenses.

Unlike many other benefit accounts, the employee owns the HSA entirely. That means the funds stay with them even if they change jobs, switch health plans, or retire.

How do HSAs work?

HSAs offer a triple-tax advantage: contributions go in tax free, the account grows tax free, and spending on qualified medical expenses is tax free.¹

Unused funds also roll over every year with no expiration date. Instead of losing what they don’t spend, your employees can build savings over time.

How can employees make the most out of an HSA?

Employees can use it to pay for thousands of qualified medical expenses, including dental and vision costs, using an HSA debit card or reimbursement. But they don’t have to spend those dollars each calendar year. Many members maximize their contributions, take advantage of employer contributions, and pay for out-of-pocket expenses with enough left over to let their HSA balance grow.

Once an employee reaches a certain balance threshold, many HSA providers allow the account holder to invest a portion of their funds in mutual funds for potential long-term, tax-free growth.²

For employees who don’t need to tap the funds right away, that can turn an HSA into a long-term savings vehicle or even a retirement planning tool.

Who is eligible for an HSA?

To qualify for an HSA, an employee must:

Enroll in an HSA-qualified high-deductible health plan (HDHP).
Have no disqualifying additional health coverage, such as Medicare or a general-purpose healthcare FSA.
Not be claimed as a dependent on someone else’s tax return.
Be at least 18 years old.

So, what can you offer employees who want another way to set aside pre-tax dollars without losing HSA eligibility? That’s where the LPFSA becomes a valuable complementary option.

What is a Limited Purpose Flexible Spending Account?

A Limited Purpose Flexible Spending Account (LPFSA) is an employer-sponsored account that allows employees to set aside pre-tax dollars exclusively for eligible dental and vision expenses.

Despite the word “limited” in its name, an LPFSA can cover a surprisingly broad range of costs. And importantly, it’s compatible with an HSA.

What can an LPFSA be used for?

Common LPFSA eligible expenses include:

Routine dental cleanings and exams
Orthodontia, including braces and Invisalign
Dentures
Eye exams
Eyeglasses and contact lenses
LASIK and other vision correction procedures
Occlusal mouth guards
Certain over-the-counter items, like eye drops and oral pain relievers

How does an LPFSA work?

Like other flexible spending account (FSA) types, an LPFSA gives the employee access to their entire contribution amount on the first day of the plan year, even though payroll deductions are spread evenly across each paycheck.

Think about an employee who knows they’ll face a big dental or vision expense early in the year. They don’t have to wait for their payroll deductions to accumulate before accessing the full amount they elected.

Do LPFSA funds roll over?

LPFSAs generally follow a use-it-or-lose-it rule, although some plans may offer a limited carryover or a grace period. Check your specific plan documents to understand what applies.

This makes employee education important. Your employees need to plan their LPFSA contributions carefully by estimating their expected dental and vision costs rather than over-contributing. They also may plan ahead for visits and procedures to ensure funds get used in the plan year.

Who is eligible for an LPFSA?

Employees may be eligible if their employer offers an LPFSA and they meet the plan’s participation rules.

Unlike HSAs, there’s no HDHP enrollment requirement for LPFSAs. That makes it an option for employees who aren’t enrolled in a high-deductible health plan.

Does an LPFSA affect HSA eligibility?

Here’s one of the most important distinctions to communicate during open enrollment: An LPFSA does not disqualify an employee from also contributing to an HSA.

Unlike a general-purpose healthcare FSA, which does disqualify HSA contributions, the LPFSA was designed to work alongside an HSA rather than compete with it.

How can an HSA and LPFSA work together?

You don’t have to frame the HSA and LPFSA as an either/or decision for your employees. It’s more accurate and more useful to think of them as complementary tools.

Here’s how the two accounts compare:

Feature	HSA	LPFSA
Purpose	Savings and spending on all qualified medical expenses	Spending on eligible dental and vision expenses only
Eligibility	Must be enrolled in an HDHP	Available to any employee whose employer offers it
Fund availability	Available as contributions are made (plus any employer contribution)	Full annual election available on day one
Rollover	Unused funds roll over indefinitely	Generally use-it-or-lose-it, subject to plan-specific grace periods
Ownership	Employee-owned and portable	Employer-sponsored and subject to plan rules; unused funds are forfeited when the employee leaves or when the plan year ends
Investment potential	Can be invested for long-term, tax-free growth	Not available for investment

When should employees choose an HSA versus an LPFSA?

When you’re helping employees understand their options, timing and predictability are two important considerations:

An HSA may be useful for employees who want to cover qualified medical expenses as they arise while building savings for future healthcare costs.
An LPFSA may be useful for employees who can anticipate dental and vision expenses for the coming year, especially larger, planned costs.
Using both, when eligible, can help employees cover predictable dental and vision costs with an LPFSA while preserving HSA funds for broader qualified medical expenses and long-term savings.

Helping employees get more from HSAs and LPFSAs

Your employees are counting on your organization to offer benefits that genuinely help them manage their costs.

An HSA and an LPFSA aren’t competing options. When you offer both, you’re giving your workforce more control over how they manage healthcare spending. That can translate into better financial readiness in the facing of rising healthcare costs.
