On December 28, 2018, the IRS Office of the Chief Counsel released Informational Letter 2018-0033 to clarify when employers can request to recover mistaken HSA contributions. This letter should be used to interpret IRS Notice 2008-59, the previous guidance that served as a primary source of information on HSA issues and administrative procedures.
The letter states that situations previously set forth in IRS Notice 2008-59 were not intended to be an exclusive list, and as long as the parties are put in the same position they would have been had the error not occurred, employers can request excess contributions be returned when they were a result of an administrative or process error.
