Substantiation
Documentation proving that HSA distributions were used for qualified medical expenses.
What is Substantiation?
Substantiation is the documentation you need to prove that your HSA distributions were used for qualified medical expenses. This typically means keeping receipts, Explanation of Benefits (EOBs), and other records that show the date of service, provider, and amount paid.
Unlike FSAs, HSAs don't require pre-approval or substantiation at the time of distribution. You're on the honor system. However, if the IRS audits your return, you'll need documentation to prove your HSA distributions were legitimate.
Best practice is to keep records indefinitely, especially if you're using the "shoebox strategy" of accumulating receipts for future reimbursement. Organize receipts by year and expense type, and consider scanning them for digital backup.
Frequently Asked Questions
How long should I keep HSA receipts?
Keep them indefinitely, or at least until you've reimbursed the expense and the tax year is closed (usually 3-7 years after filing).
What counts as valid substantiation?
Receipts, invoices, or EOBs that show the date, provider, service description, and amount. Credit card statements alone aren't sufficient.
Do I need to submit receipts to my HSA provider?
No. HSA custodians don't require substantiation at distribution. But keep records for potential IRS audits.
