This study examines land value tax equity in Taipei. The empirical results show that the variation in assessment ratios is large in the city. The horizontal equity does not hold because some districts have higher assessment ratios than the others. In addition, the land value taxation is shown to be regressive. This study also shows that the median assessment ratio is about 18% in Taipei. So, people may ignore the inequity issue in land value tax because of the small amount of this tax for each house. However, in the face of fiscal difficulties, it is possible that local governments will increase land value tax in order to raise more revenue. As a result, local governments may need to improve assessment quality to avoid possible complaint about land value tax in the future.
