In order to qualify for a Health Savings Account (HSA), you must be in a High-Deductible Health Plan (HDHP). If your insurance is single or family coverage will determine how much you eligible to contribute into the account annually. Deposits can be made by either you and/or your employer, up to your annual maximum contribution limit. The funds can be carried over from year to year for future qualified expenses. Your HSA will follow you as you change employment, and you needn’t be employed to contribute as long as you have a HDHP. A Flexible Spending account (FSA) is only offered as part of a benefits package from an employer. It has a lower annual contribution amount. Most have a "use it or lose it" rule, meaning you lose any amount you haven’t spent at the end of the year. However, some employers may allow a maximum rollover of $500. Both may offer some unique tax advantages.
