Can You Do a Flex Spend and an HSA? - Understanding the Differences and Benefits

When it comes to managing healthcare expenses, many people often wonder whether they can have both a flexible spending account (FSA) and a health savings account (HSA). While both accounts offer tax advantages, there are notable differences between the two.

Flex Spend (FSA) and HSA are both designed to help individuals save money for medical expenses, but the rules and benefits associated with each account vary.

Here's a breakdown of the main differences between Flex Spend (FSA) and HSA:

  • FSA:
    • Pre-tax contributions
    • Use-it-or-lose-it rule (some plans may allow carryover or grace period)
    • Employer-sponsored
    • General purpose for medical expenses
  • HSA:
    • Pre-tax or tax-deductible contributions
    • Roll-over feature (unused funds carry over year to year)
    • Self-sponsored or employer-sponsored
    • Requires a high-deductible health plan (HDHP)
    • Investment options for long-term savings

Now, can you have both an FSA and an HSA at the same time? The short answer is yes, but there are a few considerations to keep in mind:

  • If you have an HSA, you can also have a limited-purpose FSA for certain qualified expenses not covered by the HSA.
  • You cannot have a general purpose FSA if you have an HSA, as it would make you ineligible for the HSA tax benefits.
  • Employers may offer a grace period or carryover option for FSAs to allow some flexibility in using the funds.

In conclusion, having both an FSA and an HSA can provide you with additional flexibility and savings for your medical expenses. It's essential to understand the rules and benefits of each account to maximize your healthcare savings.


When navigating the world of healthcare expenses, many ask if it’s possible to maintain both a flexible spending account (FSA) and a health savings account (HSA). The answer is yes, and it can really enhance your ability to save on medical costs.
