What is the Best Documentation for HSA Purchases?

When it comes to making purchases with your HSA (Health Savings Account), having proper documentation is crucial for smooth transactions and to comply with IRS regulations. The best documentation for HSA purchases includes:

  • Receipts: Keep all receipts for medical expenses paid using your HSA funds. This includes doctor visits, prescriptions, medical treatments, and other eligible expenses.
  • Explanation of Benefits (EOB): Obtain and keep EOBs from your health insurance company to show what portion of the expenses were covered and what you're responsible for.
  • Invoice or Bill: Save a copy of the invoice or bill from the healthcare provider detailing the services provided and the amount charged.
  • Pharmacy Records: If your HSA was used for prescription medications, retain pharmacy records showing the medication details and cost.

Having these documents on hand will make it easier to verify your HSA purchases and provide necessary proof in case of an audit or verification request.


When using your HSA (Health Savings Account) for eligible purchases, it's essential to understand the necessary documentation to ensure you stay compliant with IRS regulations. The most effective documentation includes items such as:

  • Receipts: Always keep detailed receipts for any medical expenses you cover using your HSA funds. This not only includes doctor visits but also expenses related to prescriptions, medical treatments, and other qualifying health-related costs.
  • Explanation of Benefits (EOB): Be sure to collect EOBs from your health insurance provider, which will clarify what part of your medical expenses were covered and what you are responsible for paying out of pocket.
  • Invoices or Bills: Save copies of any invoices or bills from healthcare providers that outline the services rendered and the charges incurred.
  • Pharmacy Records: If you've used your HSA for purchasing prescription medications, it's vital to keep pharmacy records that detail the medicines you bought and their respective costs.
