Can I Have Another Health Insurance for One Month Overlap and Still Have an HSA?

Many individuals wonder if they can still have a Health Savings Account (HSA) while having another health insurance for a one-month overlap. The good news is that you can have both an HSA and another health insurance that overlaps for a brief period, such as a month. However, there are specific rules and considerations to keep in mind. Here's what you need to know:

  • Having another health insurance for a short overlap period does not disqualify you from having an HSA.
  • To be eligible to contribute to an HSA, you must be covered by a High Deductible Health Plan (HDHP) and have no other disqualifying health coverage.
  • If your other health insurance during the overlap month is not an HDHP and does not provide disqualifying coverage, you can still contribute to your HSA.
  • Once the overlap period ends, you must maintain HSA-eligible coverage to continue contributing to your HSA and receive tax benefits.
  • If you are unsure about the eligibility of your other health insurance, it is advisable to consult with a benefits administrator or tax professional to avoid any penalties.

While having another health insurance overlapping with your HSA-eligible coverage for a short duration is permissible, it is crucial to ensure that you meet all HSA eligibility requirements to maximize the benefits of your HSA.


If you're navigating the waters of health insurance and HSAs, you might find yourself asking: can I maintain my Health Savings Account (HSA) while having another health insurance policy for a brief overlap? The answer is yes! You can seamlessly manage both your HSA and another health insurance for short durations, such as one month. However, there are essential regulations you should be aware of:

  • The existence of another health insurance, even for a short period, does not disqualify you from having an HSA.
  • In order to contribute to your HSA, you need to be enrolled in a High Deductible Health Plan (HDHP) without any other disqualifying health coverage.
  • If your overlapping insurance is not an HDHP but does not offer disqualifying coverage, you remain eligible to contribute to your HSA.
  • After the overlap period, to continue contributing to your HSA and enjoy its tax advantages, maintaining HSA-eligible coverage is mandatory.
  • Consulting a benefits administrator or tax professional about your health insurance options is a wise move to ensure you comply and avoid unexpected penalties.

In conclusion, while you can have a temporary overlap of health insurance, ensuring you meet the necessary eligibility requirements for your HSA is key to maximizing its benefits.
