Federal budget of Switzerland
The budget principles are defined by the Swiss Constitution and have been restated most recently in the 1999 fiscal guidelines of the confederation. In 2010 the federal budget of Switzerland had a size of 62.8 billion Swiss francs, which is an equivalent 11.35% of the country's GDP in that year. In 2014 the federal budget of Switzerland had an estimated size of 66.353 billion Swiss francs, which is an estimated equivalent 10.63% of the country's GDP in that year.
Note that the Swiss "federal" budget only comprises 31.7% of Swiss public expenditure, the rest being managed by the cantons and the municipalities directly.
