what is covered by FSA when I have also HSA
HSA Differences. A health savings account is similar to an FSA, because your HSA contributions are also made before taxes. However to contribute to an HSA, you must be covered by a high-deductible health plan. An FSA does not have this requirement.ou are forbidden from contributing to an FSA and an HSA at the same time. Because both of these plans result in tax savings, the U.S. government is concerned that some people could take advantage of both plans to increase their tax savings over what is otherwise allowed.
