In addition to the money spent through the government budget, policies are also financed with non-budgetary expenditures. Firstly these are social security and health care contributions. Although not part of the budget process, the government may impose demands on, for example, the amount of premiums and the coverage of mandatory insurance. In addition, tax instruments are used, such as specific tax rebates and deductions. These are not expenses, but of course, do affect the total amount of money government receives.
