The reversal of a gift can occur due to a legal provision, a regulation in the gift contract, or a subsequent agreement between the parties involved. From a tax law perspective, it is questionable whether the tax incurred for the gift will be refunded and whether the reversal process might trigger a tax liability again. This work examines the respective tax law implications based on civil law reversal scenarios. According to the systematic requirements of the applicable inheritance and gift tax law, the gift tax must be refunded if the reversal creates a situation that would have existed had the gift not taken place.
