* For the purposes of the OECD's report, “taxes” is confined to compulsory, unrequited payments to general government. Taxes are unrequited in the sense that benefits provided by government to taxpayers are not normally in proportion to their payments. In the OECD classification, taxes are classified by the base of the tax: income and profits, payroll, property, consumption and other taxes. Compulsory social security contributions
paid to general government also are treated as taxes.
