How the Shoebox Strategy Works
Pay Out-of-Pocket
Pay for medical expenses with cash or a credit card instead of your HSA debit card.
Save Receipts
Keep documentation of every expense. This is where HSA Tracker comes in.
Reimburse Later
Years later, reimburse yourself tax-free for all those expenses. No time limit.
No Expiration on Reimbursement
The IRS has no time limit. Expenses from 10+ years ago can be reimbursed tax-free today.
The Key: Good Records
The IRS requires you to keep receipts. That's why tracking expenses digitally is essential.
Expense Must Post-Date HSA
Only expenses incurred after you opened your HSA qualify. You can't reimburse past expenses.
Best for Long-Term Investors
This strategy shines when you have years to let investments compound tax-free.
