The reader is referred to Table 1.9 of Revenue Statistics, 1965-2015 (OECD, 2017). All governments raise revenue from a mix of taxes, fees and a variety of non-tax sources of income. The OECD identities six categories of taxation: i) Taxes on personal income; ii) Social security contributions; iii) Corporate income taxes; iv) Consumption taxes; v) Property taxes; and vi) other taxes.
