During the period 1991–2004, political support for the inheritance and gift taxation in Sweden diminished, which contributed to two major policy shifts. In 1991, a new tax schedule which reduced top rates was introduced. The tax was thereafter completely repealed in 2004. In this paper, we examine how background factors such as competitiveness and political legitimacy influenced these decisions. By studying the preceding decision-making processes, we find that the influence of these factors shifted over time and appeared in different combinations. While the 1991 reform was strongly influenced by competitiveness arguments, the repeal of the inheritance and gift tax was primarily a result of the declining legitimacy of the tax.
