What are HSA or FSA accounts?
HSAs (Health Savings Account) and FSAs (Flexible Savings Accounts) are accounts that allow you to set aside pre-tax money to be spent on health related purchases. On average, consumers save 30% on health related purchases by using HSA/FSA funds.
What can HSA or FSA funds be spent on?
HSA/FSA funds can be spent on products or services related to the diagnosis, cure, mitigation, treatment, or prevention of disease. Today, most people spend their HSA/FSA funds on doctor visit copays and pharmacy items but there are many direct to consumer health and wellness products and services that may also qualify.
Why can't I just accept HSA/FSA cards in my existing checkout flow?
- It depends on your business! If you are a ecommerce store selling HSA/FSA eligible items, you are required by the IRS to use an Inventory Information Approval System (IIAS). This system must auto-substantiate HSA/FSA transactions at the point of sale in order for consumers to use their HSA/FSA cards.
- If you are a wellness business (fitness, nutrition, sleep etc), your product or service may not be explicitly eligible by the IRS. Consumers must receive a Letter of Medical Necessity from a physician deeming your product medically necessary before you can accept HSA/FSA funds.
- The good news is that Flex can help in either situation. If you aren't sure about your use case, we're happy to chat and explore your specific needs.
