What is a medical savings accounts (MSA) or health savings account (HSA)?

Savings accounts designated for out-of-pocket medical expenses. In an MSA, employers and individuals are allowed to contribute to a savings account on a pre-tax basis and carry over the unused funds at the end of the year. One major difference between a Flexible Spending Account (FSA) and a Medical Savings Account (MSA) is the ability under an MSA to carry over the unused funds for use in a future year, instead of losing unused funds at the end of the year.  Unlike FSAs, most MSAs are combined with a high deductible or catastrophic health insurance plan.
