What If I Have HSA and FSA? Understanding the Differences and Benefits

Many people often wonder what happens if they have both a Health Savings Account (HSA) and a Flexible Spending Account (FSA). While both accounts offer tax advantages and help you save on healthcare costs, there are key differences between the two that you need to be aware of.

When it comes to having both an HSA and FSA:

  • You cannot contribute to both accounts in the same year.
  • If you have both, you can use your FSA funds for qualified medical expenses before dipping into your HSA funds.
  • Having both accounts gives you more flexibility in covering healthcare costs.

It's important to manage your contributions and expenses carefully to maximize the benefits of both accounts. Remember that FSA funds do not roll over year to year, unlike HSA funds, which can be carried over and invested for future use.


Many individuals find themselves in a unique situation when they have both a Health Savings Account (HSA) and a Flexible Spending Account (FSA). Understanding the nuances between these two can help you optimize your savings. While both accounts help with healthcare costs and tax breaks, remember that contributions to each account have specific rules when used in conjunction.
