Do excess contribution rules and prohibited transaction rules apply to HSAs?
Yes. In fact, the rules are very similar to IRA rules. A 6% excise tax will be owed if an excess contribution is made and it is not corrected within a specified time frame. If an HSA participates in a prohibited transaction, the HSA will cease to be an HSA on the first day of the year. For more information on this subject, review the IRS website at www.irs.gov.
