FSA funds must be spent by year-end or forfeited, and qualifying purchases extend beyond typical doctor visits.

Over-the-counter medications qualify, including pain relievers, cold medicine, bandages, dental care products, and menstrual products. You can stock up on these items now.

Fitness trackers and smartwatches can qualify as FSA-eligible purchases, but they require a Letter of Medical Necessity to justify the expense. Screenless recovery trackers like Whoop, Amazfit Helio Strap, and the Oura Ring typically qualify based on sleep quality, stress monitoring, or recovery tracking tied to a chronic condition. Coros offers FSA/HSA eligibility for all its watches and heart rate monitors through a partnership with Truemed. Amazfit lets you filter by HSA/FSA eligibility for its smartwatches.

Other eligible items include Epsom salt for $8.99, Supergoop sunscreen for $38.00, and massage guns for $349.99 through the official FSA store.

Orthopedic items like knee braces, wrist splints, and compression socks also qualify. If you wear eyeglasses or contacts, you can use FSA dollars to update prescriptions, eye drops, and lens solution.

Some healthcare providers allow you to pre-pay estimated costs for procedures scheduled in early next year, including dental work, physical therapy, chiropractic visits, and Lasik eye surgery. Check your employer's specific FSA rules for December 31 deadlines to avoid forfeiting remaining funds.
