No. A merchant is not required to implement an IIAS; however, FSA/HRA card issuers will not be able to approve FSA/HRA card transactions when a merchant does not support an IIAS. If you are a merchant and choose not to implement an IIAS, you do not need take additional steps. Merchants that are pharmacies/drug stores and primarily sell prescriptions and medical items may qualify under the IRS rules as a “90% Rule” merchant. See the 90% Rule Merchant FAQs for more information.
For merchants that would like to accept the FSA/HRA cards from their customers, the IRS requires Merchants selling health care eligible products to support an Inventory Information Approval System (IIAS). The IIAS system is a combination of inventory management and point-of-sale systems that can verify the health care eligibility of items purchased with an FSA or HRA debit card, generate a payment transaction that contains the required IIAS information, and includes an information archive system that allows the merchant to respond to an IRS audit(s) as required. As noted above, for Drug Stores / Pharmacies where 90% of the sales on a store-by-store basis qualify as FSA-eligible, a 90% Rule registration program is an alternative option.
Merchants have the option to not become a Member of SIGIS by establishing their own IIAS standards or 90% Rule Exemption and working with third-party plan administrators individually.
With the IIAS Certification developed by SIGIS, a non-profit standards organization, a broad range of participating merchants have been able to implement a solution that is recognized industry-wide, which enables acceptance of most FSA/HRA payment cards. Likewise, third-party plan administrators have implemented a common set of procedures that are applied to IIAS transactions at participating merchants.
