A fitness tracker, gym membership, ergonomic chair, an air conditioner — if you didn't know your FSA or HSA may cover these items, you may not be getting the biggest bang for your buck out of these popular health care savings accounts.
Flexible Spending Accounts and Health Savings Accounts both allow people to squirrel away pretax money to spend on eligible health care expenses.
Some key differences: While HSAs allow you to carry over any unused contributions into the next year, the balance in health FSAs often expires at the end of the year. Any money unspent in FSAs may be lost.
