The biggest issue with property taxes is not whether rates are too high or low, but that the assessed values of properties tend to be low. Local governments make those assessments, so it would be useless for the central government to raise rates.
因為地價稅最大的問題不是稅率高低，而是公告地價偏低，公告地價也是地方政府自己訂的，光靠中央把稅率提高也沒有用。
