Can You Go Back to FSA if You Have an HSA? - Exploring the Differences and Transition Options

Health savings accounts (HSAs) and flexible spending accounts (FSAs) are both popular options for managing medical expenses, but they have key differences that impact eligibility and contributions. One common question that arises is whether you can go back to an FSA if you have an HSA.

Firstly, it's important to understand that an individual cannot have both an HSA and a general purpose FSA at the same time. However, there are certain exceptions and transition options to consider:

  • If you switch from an HSA-eligible health plan to a non-HSA eligible plan, you can spend down your HSA balance and return to an FSA for eligible expenses.
  • If you are no longer eligible to contribute to an HSA (e.g., due to enrolling in Medicare), you can still use the remaining HSA funds for qualified medical expenses but cannot make new contributions. In this case, you may also be able to enroll in a limited-purpose FSA for dental and vision expenses.
  • If you enroll in a high-deductible health plan (HDHP) mid-year, you can contribute to an HSA for that period and then switch to an FSA for the remainder of the year if needed.

It's crucial to carefully review your options and consider the impact on your finances and healthcare coverage when transitioning between accounts. Consulting with a benefits specialist or financial advisor can provide personalized guidance based on your specific situation.


Health savings accounts (HSAs) and flexible spending accounts (FSAs) are two effective ways to manage healthcare costs, yet they differ significantly in terms of eligibility and contribution rules. Understanding whether you can revert to an FSA after having an HSA is essential for making informed financial decisions regarding your health expenses.
