Extra taxes for the government

It is proposed that various taxes including Property Tax be imposed by the government to increase the revenue as well as reducing the gap between the poor and the rich. The best method is an inheritance tax above a certain threshold which is followed by all western countries and which has narrowed the gap between the poor and the rich. Such tax has siphoned off the power of elites and aristocratic dynasties and the landed gentry from the western world and has encouraged philanthropic tax-free donation habit. I implore the government to introduce such a tax as well.
