40. Classified here are all compulsory payments to general government that confer an entitlement to receive a (contingent) future social benefit. Such payments are usually earmarked to finance social benefits and are often paid to institutions of general government that provide such benefits. However, such earmarking is not part of the definition of social security contributions and is not required for a tax to be classified here. However, conferment of an entitlement is required for a tax to be classified under this heading. So, levies on income or payroll that are earmarked for social security funds but do not confer an entitlement to benefit are excluded from this heading and shown under personal income taxes (1100) or taxes on payroll and workforce (3000). Taxes on other bases, such as goods and services, which are earmarked for social security benefits are not shown here but are classified according to their respective bases because they generally confer no entitlement to social security benefits.
41. Contributions for the following types of social security benefits would, inter alia, be included: unemployment insurance benefits and supplements, accident, injury and sickness benefits, old-age, disability and survivors’ pensions, family allowances, reimbursements for medical and hospital expenses or provision of hospital or medical services. Contributions may be levied on both employees and employers.
42. Contributions may be based on earnings or payroll (‘on a payroll basis’) or on net income after deductions and exemptions for personal circumstances (‘on an income tax basis’), and the revenues from the two bases should be separately identified if possible. However, where contributions to a general social security scheme are on a payroll basis, but the contributions of particular groups (such as the self-employed) cannot be assessed on this basis and net income is used as a proxy for gross earnings, the receipts may still be classified as being on a payroll basis. In principle, this heading excludes voluntary contributions paid to social security schemes. When separately identifiable these are shown in the memorandum item on the financing of social security benefits. In practice, however, they cannot always be separately identified from compulsory contributions, in which case they are included in this heading.
43. Contributions to social insurance schemes which are not institutions of general government and to other types of insurance schemes, provident funds, pension funds, friendly societies or other saving schemes are not considered as social security contributions. Provident funds are arrangements under which the contributions of each employee and of the corresponding employer on his/her behalf are kept in a separate account earning interest and withdrawable under specific circumstances. Pension funds are separately organised schemes negotiated between employees and employers and carry provisions for different contributions and benefits, sometimes more directly tied to salary levels and length of service than under social security schemes. When contributions to these schemes are compulsory or quasi-compulsory (e.g., by virtue of agreement with professional and union organisations) they are shown in the memorandum item (refer to Table 5.38 of the Report).
44. Contributions by government employees and by governments in respect of their employees, to social security schemes classified within general government are included in this heading. Contributions to separate schemes for government employees, which can be regarded as replacing general social security schemes, are also regarded as taxes.14 Where, however, a separate scheme is not seen as replacing a general scheme and has been negotiated between the government, in its role as an employer, and its employees, it is not regarded as social security and contributions to it are not regarded as taxes, even though the scheme may have been established by legislation.
45. This heading excludes ‘imputed’ contributions, which correspond to social benefits paid directly by employers to their employees or former employees or to their representatives (e.g., when employers are legally obliged to pay sickness benefits for a certain period).
46. Contributions are divided into those of employees (2100), employers (2200), and self-employed or non-employed (2300), and then further sub-divided according to the basis on which they are levied. Employees are defined for this purpose as all persons engaged in activities of business units, government bodies, private non-profit institutions, or other paid employment, except the proprietors and their unpaid family members in the case of unincorporated businesses. Members of the armed forces are included, irrespective of the duration and type of their service, if they contribute to social security schemes. The contributions of employers are defined as their payments on account of their employees to social security schemes. Where employees or employers are required to continue the payment of social security contributions when the employee becomes unemployed these contributions, data permitting, are shown in 2100 and 2200 respectively. Accordingly, the sub-heading 2300 is confined to contributions paid by the self-employed and by those outside of the labour force (e.g., disabled or retired individuals).
