How RetroHSA Works in 3 Simple Steps

From snapping a crumpled pharmacy slip to generating an audit-ready Reimbursement Report in retirement.

Step 1

Snap or Drop Any Receipt

Use your phone camera or drag and drop PDFs, hospital statements, and pharmacy receipts. Thermal paper fades to blank white in 18 months—RetroHSA preserves digital originals untouched for life.

Step 2

AI Line-Item Verification

Automatically itemizes charges, checks dates against your HSA establishment date, and filters out ineligible charges (like cosmetics or general toiletries) to protect you from the 20% IRS penalty.

Step 3

Claim Tax-Free Cash Anytime

Whenever you want to withdraw from your HSA—next year or 25 years from now—enter your amount to generate a stamped Reimbursement Report with every receipt indexed and matched to Line 15.

2. Line-Item Audit Guardrails

Itemizes individual charges so you can toggle qualified vs. non-qualified items (per IRS Pub 502), flags unpaid insurance bills until payment proof is attached, and verifies dates against your HSA establishment date.
