What an FSA is

A health Flexible Spending Arrangement (FSA) lets employees get tax-advantaged reimbursement for medical expenses, usually via salary reduction; employers may also contribute (Pub. 969).

Benefits include possible income/employment-tax savings on contributions, tax-free qualified reimbursements, and often access to the full annual election before payroll fully funds it.
