Tax law
Tax law is part of public law. It covers the application of existing tax laws on individuals, entities and corporations, in areas where tax revenue is derived or levied, e.g. income tax, estate tax, business tax, employment/payroll tax, property tax, gift tax and exports/imports tax. There have been some arguments that consumer law is a better way to engage in large-scale redistribution than tax law because it does not necessitate legislation and can be more efficient, given the complexities of tax law.
