What’s an HSA or FSA?

Health Savings Accounts (HSAs) let you set aside pre-tax dollars to pay for qualified health expenses. HSAs are linked to high-deductible health plans, and funds in these accounts roll over year after year.

Flexible Spending Accounts (FSAs) allow you to use pre-tax dollars for eligible health expenses. Unlike HSAs, FSAs are not tied to a specific health plan and often require you to use the funds within the calendar year. FSAs are typically provided by employers.
