Understanding HSA & FSA Account Requirements
Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) are tax-advantaged accounts utilized by consumers to fund qualified medical and healthcare expenses. While both access funds via specialized debit card networks, strict Internal Revenue Service (IRS) regulations govern how and where these cards can be accepted.
Health Savings Accounts (HSA)
Eligibility: Tied to High Deductible Health Plans (HDHP).
Rollover Rule: Unused account balances roll over indefinitely year-over-year.
Substantiation: Less restrictive at authorization, though purchases must still meet qualifying medical criteria.
Flexible Spending Accounts (FSA)
Eligibility: Offered through employer benefit plans without HDHP requirements.
Expiration Rule: Subject to "use-it-or-lose-it" annual expiration mandates.
Substantiation: Strict IRS point-of-sale verification required via certified IIAS platforms.
IRS Compliance & IIAS Inventory Approval Systems
Under IRS regulations, merchants that are not primary medical service providers (e.g., general pharmacies, supermarkets, online wellness retailers) must support an Inventory Information Approval System (IIAS) to accept FSA or HSA cards. An IIAS automatically verifies at checkout whether individual item UPC codes qualify as tax-exempt medical expenses before allowing authorization.
Checkout Optimization via HSA/FSA BIN Lookup:
Pre-identifying an HSA or FSA card via BIN lookup allows checkout software to split payments dynamically. Non-qualifying items in a shopping cart can be directed to a standard credit card, while qualifying items are routed to the HSA/FSA card, avoiding hard authorization declines.
