Flexible Spending Accounts (FSAs) operate on a “use it or lose it” rule. Any unused balance at the end of the plan year (usually December 31, 2026) is forfeited unless your employer offers a grace period or carryover. In 2026 the employee contribution limit for a health care FSA is $3,400. Knowing exactly what you can spend on and when can save you hundreds of dollars. This guide explains how to maximize your 2026 FSA before the deadline. 2026 FSA deadlines and rules Most plan years end December 31, 2026. Many employers offer a 2½-month grace period (until March 15, 2027) or a carryover of up to $680 into 2027. Check your plan documents or summary plan description for your exact rules. Eligible FSA expenses You can use FSA funds for IRS-qualified medical, dental, and vision expenses, including: Doctor visits, copays, deductibles, and coinsurance Prescription and over-the-counter medications (with a prescription for some items) Dental cleanings, fillings, braces, and orthodontics Vision exams, glasses, contacts, and LASIK Eligible over-the-counter items such as bandages, first-aid supplies, sunscreen, and menstrual products Certain wellness items (check your plan) You cannot use FSA dollars for health insurance premiums, gym memberships, or cosmetic procedures.

Stock up on eligible over-the-counter supplies. Submit reimbursement requests early Save all receipts. Submit claims as soon as you incur the expense rather than waiting until year-end.
