FSA / HSA Tax-Free Buying Guide

Smart sleep and physical trackers are FSA/HSA eligible in the US. This lets you purchase with pre-tax income, saving up to 30% to 40% depending on your tax bracket!

1

Verify Eligibility

Devices like Oura Ring 4, Oura Ring 5, Samsung Galaxy Ring, and Ultrahuman Ring Air are officially classified as medical diagnostic equipment for sleep. No doctor's Letter of Medical Necessity (LMN) is needed!

2

Pay Directly (Amazon / Brand Site)

Add your HSA/FSA debit card directly to your Amazon account wallet as a credit/debit card, or input it during checkout on the brand site. Select it at checkout to charge your health fund directly!

Alternative: Submit Reimbursement

If your card gets declined (some administrators restrict online transactions), checkout using a normal credit card, download the itemized invoice/receipt, and submit it to your health savings administrator portal.
