How to Accept HSA and FSA Payments at Your Business

Key Takeaways

  • Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) are prepaid debit cards that customers use for eligible medical and health expenses
  • Businesses in certain categories, including pharmacies, medical supply retailers, and some wellness businesses, can accept HSA/FSA cards with the right setup
  • Accepting HSA/FSA payments requires a certified payment terminal that supports IIAS (Inventory Information Approval System) or a merchant eligible for automatic approval
  • PaymentCollect’s payment terminals support HSA/FSA card acceptance for eligible merchants

 

More customers are paying for health-related purchases with HSA and FSA cards than ever before. According to the Employee Benefit Research Institute, Americans held more than $116 billion in HSA accounts as of 2023, with account balances growing at a double-digit rate year over year. If your business sells products or services that qualify as eligible expenses under IRS guidelines, not accepting these cards means turning away a payment method your customers are actively trying to use.

0 1What Are HSA and FSA Cards?

Health Savings Accounts and Flexible Spending Accounts are employer-sponsored or individually-held accounts that allow people to set aside pre-tax dollars for qualified medical expenses. Both types of accounts typically issue a debit card that draws directly from those funds.

HSA cards are tied to high-deductible health plans and have no use-it-or-lose-it deadline. FSA cards are offered through employers and typically require funds to be spent by the end of the plan year. From a payment acceptance standpoint, both function similarly: the customer presents a debit card at the point of sale, and the transaction is processed against the account balance.

The distinction that matters for merchants is what happens at the authorization stage. HSA/FSA cards are governed by IRS rules about eligible expenses, and card networks require merchants in certain categories to have systems in place that verify the eligibility of each item being purchased.

Which Businesses Can Accept HSA and FSA Payments?

Not every business can accept HSA/FSA cards. The IRS defines eligible expenses, and Visa and Mastercard have built compliance requirements around merchant eligibility to protect cardholders from using these pre-tax funds on non-qualifying items.

Businesses that typically qualify to accept HSA/FSA cards include:

  1. Pharmacies and drug stores (auto-approved at the MCC level)
  2. Medical supply retailers selling items like blood pressure monitors, diabetic supplies, or wound care products
  3. Vision care providers and optical shops
  4. Dental offices and orthodontic practices
  5. Hearing aid retailers
  6. Certain wellness and physical therapy providers
  7. Retailers whose product mix is predominantly eligible medical or health items

If your business category is not auto-approved by the card networks, you may need an Inventory Information Approval System (IIAS) to route HSA/FSA transactions correctly. IIAS-certified systems identify which items in a transaction are eligible and which are not, authorizing only the eligible portion against the HSA/FSA card.

If you are not sure whether your business qualifies, the PaymentCollect sales team can help you determine your eligibility before you invest in any new equipment.

What Is IIAS and Do You Need It?

IIAS stands for Inventory Information Approval System. It is a technology standard that allows a payment terminal or POS system to separate eligible items from non-eligible items during checkout and apply the HSA/FSA card only to the qualifying portion of the sale.

For merchants that are auto-approved (pharmacies and medical providers in specific MCC codes), IIAS is not required. The card network automatically permits these transactions.

For other merchants, IIAS integration is the path to accepting these cards. This requires the right combination of POS software and terminal hardware. According to Sigis, the nonprofit that certifies IIAS-compliant systems, more than 3,000 retail brands were certified as of 2024.

The PaymentCollect point of sale and its supported payment terminals support HSA/FSA card acceptance for eligible merchants, with no need to source a separate terminal or POS platform. That single-system approach eliminates the confusion that often comes from trying to piece together HSA acceptance through multiple vendors.

How the Payment Process Works at Checkout

From the customer’s perspective, paying with an HSA or FSA card is nearly identical to using any other debit card. They tap, chip, or swipe at the terminal. The system handles the rest.

Behind the scenes, here is what happens:

  1. The customer presents their HSA or FSA debit card
  2. The terminal identifies the card type and routes it through the appropriate network
  3. If the merchant is auto-approved, the transaction is authorized against the available balance
  4. If IIAS is required, the system separates eligible and non-eligible items and submits only the eligible total for HSA/FSA authorization
  5. If the HSA/FSA balance is insufficient for the full eligible amount, many systems allow a split tender, applying the HSA/FSA card to the eligible portion and a separate card to the remainder

Split tender capability is important for businesses where customers might have a partially depleted FSA balance near the end of the year. A payment terminal that handles split tender avoids the awkward situation of declining a card that has funds remaining.

“The number of health-related retail transactions has risen sharply since the IRS expanded the list of eligible expenses in 2020 to include over-the-counter medications and menstrual products,” notes Josh Eichhorn, a retail payments consultant. “Merchants who haven’t updated their systems to handle that volume are leaving transactions on the table every week.”

Why Accepting HSA and FSA Payments Matters for Retail and Service Businesses

There are two practical reasons to add HSA/FSA acceptance beyond customer convenience.

The first is transaction completion. A customer who wants to pay with their FSA card for a qualifying purchase and cannot complete the transaction at your register is a lost sale. According to a survey by the Mercator Advisory Group, 38% of HSA/FSA cardholders have changed where they shop specifically to find merchants that accept these cards.

The second is average ticket size. Customers spending pre-tax health dollars tend to spend more per visit because they have already mentally designated those funds for health-related purchases. Businesses in the medical supply, optical, and pharmacy space frequently report that HSA/FSA transactions carry a higher average ticket than standard credit card purchases.

Both of those outcomes, fewer lost sales and higher average tickets, improve revenue without requiring any change to your product offerings or pricing.

What Hardware Do You Need?

The hardware requirement for HSA/FSA acceptance is not separate from general payment terminal needs. Any EMV-certified terminal that supports PIN debit and is connected to a compliant processing platform can handle HSA/FSA transactions for auto-approved merchants.

For merchants requiring IIAS, the system needs to be certified. PaymentCollect’s terminals, including the PAX A80 (Ethernet/WiFi) and the PAX A920Pro (4G/WiFi/Ethernet, battery operated), are capable of supporting HSA/FSA acceptance as part of the broader payment terminal lineup.

The PAX A80 is the right choice for stationary retail setups where the terminal stays at the counter. The PAX A920Pro adds battery operation and 4G connectivity, which is useful for businesses that operate pop-up locations, attend health fairs, or need a terminal that moves around the space.

You do not need to purchase separate hardware to accept HSA/FSA cards alongside regular credit, debit, chip, and tap transactions. The same terminal handles all of it.

How to Get Started

The path to accepting HSA and FSA payments at your business starts with confirming your eligibility and then making sure your terminal and processing platform are set up correctly.

Here is the practical sequence:

  1. Confirm your Merchant Category Code (MCC) and whether it is auto-approved for HSA/FSA
  2. If IIAS is required, confirm that your POS and terminal are certified
  3. Work with your payment processor to verify the setup is complete
  4. Train staff on split tender scenarios so they can assist customers confidently

Because PaymentCollect handles payment processing, POS software, and terminal hardware under one roof, this setup conversation happens in one place, not across three separate vendors. That is the practical value of the all-in-one payment solution for businesses trying to add new payment types without adding operational complexity.

Visit the support page or reach out to the sales team to walk through the setup process for your specific business type.

Summary

HSA and FSA cards are a growing share of health-related retail and service transactions. Businesses in eligible categories that accept these cards reduce lost sales and often see higher average ticket sizes from customers spending designated pre-tax funds. Accepting them requires either auto-approval through your MCC or IIAS certification, along with a properly configured terminal and processing platform. PaymentCollect’s payment terminals and POS system support HSA/FSA acceptance without requiring a separate hardware or software vendor.

Frequently Asked Questions

Can any business accept HSA and FSA cards?

No. HSA/FSA acceptance is restricted to merchants in eligible categories, primarily healthcare providers, pharmacies, and retailers whose inventory is predominantly IRS-qualified medical or health items. Contact the PaymentCollect sales team to find out if your business qualifies.

Do I need a special terminal to accept HSA/FSA payments?

Not necessarily a special terminal, but the terminal must be EMV-certified and your processing platform must be configured correctly. For merchants requiring IIAS, the system needs to be certified to separate eligible from non-eligible items during checkout.

What happens if a customer’s HSA/FSA balance doesn’t cover the full purchase?

Many POS systems and terminals support split tender, where the HSA/FSA card covers the eligible portion and a second card covers the remainder. Make sure your setup supports split tender before enabling HSA/FSA acceptance so you can handle this scenario confidently.

Are over-the-counter medications eligible for HSA/FSA payment?

Yes. The IRS expanded eligibility in 2020 to include over-the-counter medications and menstrual care products without a prescription requirement. This expanded the number of transactions eligible for HSA/FSA payment at retail locations.

How does HSA/FSA acceptance work with QuickBooks Online?

If you are using the QuickBooks Online plugin from PaymentCollect, HSA/FSA transactions post to QuickBooks automatically alongside your other payment types. There is no separate reconciliation process.

Is there additional PCI compliance required for HSA/FSA acceptance?

HSA/FSA acceptance does not add a separate layer of PCI compliance requirements beyond what is already required for standard card acceptance. Your standard PCI compliance obligations remain the same. The card-specific rules around HSA/FSA are handled at the network and IIAS certification level.

How do I know if my product inventory qualifies as eligible expenses?

The IRS publishes a list of eligible medical expenses in Publication 502. For retail businesses, IIAS certification includes a process for tagging inventory items as eligible or non-eligible. PaymentCollect can walk you through this as part of the setup process.

Conclusion

Adding HSA and FSA card acceptance is a practical step for businesses in health-adjacent retail and service categories. The technology is already built into the terminals and platforms that PaymentCollect provides. The conversation worth having now is whether your business category qualifies and how quickly you can have it running.
