The basic aspects of the PGE are defined by article 134 of the
Spanish Constitution of 1978. The General State Budget are annual, include all the expenses and income of the state public sector and they are the amount of tax benefits that affect state taxes. Spain was a pioneer in terms of transparency in 1978 because of the introduction of this obligation with respect to tax benefits. Since these are equivalent to an indirect subsidy, they can be considered an expense and therefore must be included in the budget.
Preparation and approval The preparation of the General State Budget is the responsibility of the
Government, while its examination, amendment and approval is the responsibility of the
Cortes Generales. The Government must present before the
Congress of Deputies the General State Budget at least three months before the expiration of those of the previous year. The objective is for the budget to be approved before December 31 of each year. If the Budgetary Act is not approved before the first day of the corresponding fiscal year, the Budget of the previous fiscal year are automatically carried over until the approval of the new ones. This extension has some exception: it does not affect credits approved for activities that ended in the year whose budget is extended. In practice, when a government does not get the parliamentary support to approve the budget, the most usual thing is the holding of early elections since it is very difficult to govern and make economic policy decisions with an extended budget.
Spending limit The spending limit established in the budget is not absolute. Once the General State Budget has been approved, the Government may present bills that imply an increase in
public spending or a decrease in revenues corresponding to the same budget year. These bills must be approved by parliament. The parliament can also present a proposal or amendment that supposes an increase of the credits (expense) or a decrease of the budgetary income, but this proposal requires the agreement of the Government for its processing.
Creation and modification of taxes The Budget Act can not create
taxes. This law can only modify them when a substantive tax law so foresees.
Budget stability Article 135 of the
Constitution, modified in 2011, establishes the principles of stability and budget sustainability. Among them it is established that the credits to pay the public debt are always present in the budget and are of absolute priority. This means that even if the budget does not include a forecast of expenditure in debt payment, if there are debts, the credit for that expense is automatically understood as being included in the budget in a virtual way by this article of the constitution. The principles established in this article are developed in the Organic Law of Budget Stability and Financial Sustainability. The objective of budget stability is presented by the
Government and is established every three years according to forecasts of
economic growth. Each year a multi-year budget plan for three years must be drawn up in which the stability objective is taken into account. ==Budgets of the autonomous communities==
