Can You Use an FSA and HSA? Understanding the Differences and Benefits

Many individuals often wonder whether they can use both a Flexible Spending Account (FSA) and a Health Savings Account (HSA) concurrently to maximize their healthcare savings. While both accounts offer tax advantages, they have different eligibility requirements and rules that need to be understood to make the most of their benefits.

Understanding the Differences:

  • FSA:
    • Funded by pre-tax deductions from your paycheck
    • Subject to use-it-or-lose-it rule
    • Can be used for qualified medical expenses
  • HSA:
    • Requires a high-deductible health plan (HDHP)
    • Contributions are tax-deductible or pre-tax
    • Rolls over year after year
    • Can be used for qualified medical expenses and save for retirement

Using Both FSA and HSA:

While it is possible to have both an FSA and HSA, there are certain limitations and considerations to keep in mind:

  • You cannot contribute to both accounts simultaneously
  • If you have an FSA, you can still open an HSA but with limitations
  • If your employer offers a Limited-Purpose FSA, you can use it in conjunction with an HSA for dental and vision expenses

Consult with a financial advisor or benefits administrator to determine the best approach for your specific situation.
