Understanding FSAs & HSAs

If you think of FSAs and HSAs as simple spending accounts, you are not alone. But with the right approach, they can be more than a way to cover healthcare costs. They can also play an important role in how you budget, save, and plan for the future.

Watch a webinar recording on this topic here.

Start With the Basics

A helpful place to start is understanding the difference between the two. A Flexible Spending Account (FSA) is generally a shorter-term tool. You set aside pre-tax money for eligible healthcare, dental, and vision expenses, and the account is designed to be used during the plan year, with some plans offering a grace period or limited rollover. A Health Savings Account (HSA), on the other hand, is tied to an HSA-eligible high-deductible health plan and stays with you over time. The money is yours, and you can use it for qualified expenses now or later.

How an FSA Can Help

An FSA may work well for expected expenses you know are coming, such as copays, deductibles, dental visits, or vision care. Because FSAs are use-it-or-lose-it accounts, it helps to look back at your past few years of healthcare spending and estimate what you are likely to need in the year ahead. One advantage is that the full amount you elect is available up front, even though contributions come out of your paycheck over time.

How an HSA Can Help

An HSA may offer more flexibility. Like an FSA, it lets you use pre-tax money for eligible medical, dental, and vision expenses. But HSAs also have longer-term potential because unused dollars stay in the account year after year. That is why some people treat an HSA as both a healthcare account and a savings tool. The account offers a triple tax advantage: contributions go in pre-tax, growth is tax-deferred, and withdrawals for qualified medical expenses are tax-free.

For people who can afford to do so, that long-term potential may be especially valuable. You can able to pay current medical expenses out of pocket, save your receipts, and let your HSA balance continue to grow. As long as the expense happened after the account was opened, you can reimburse yourself later. Some account holders also choose to invest part of their HSA balance once they have enough cash set aside for near-term needs, although investment thresholds vary by plan and depend on your comfort with risk.

There is also an important connection between HSAs and FSAs. If you are enrolled in an HSA-eligible health plan, a common companion account is a Limited Purpose Flexible Spending Account. That type of FSA covers dental and vision expenses only, which can help preserve your HSA eligibility while still letting you set aside pre-tax dollars for predictable costs. A traditional Health FSA can create issues for HSA eligibility, including in some cases when a spouse is enrolled in one, so it is important to review household coverage carefully during open enrollment.

Finding the Right Fit

Picking your strategy depends on your budget and goals. Some people need these accounts to cover current expenses right away. Others use a hybrid approach, spending some dollars now and saving some for later. And for people in stronger cash-flow years, an HSA may become another piece of a longer-term savings strategy.

Wherever you start, keep good records, review your plan documents, and reach out to your HR team or advisor if you need help comparing options. A little planning can go a long way toward making these benefits easier to use and potentially more valuable over time.
