2.2. Staff and budget

For the execution of its mission, at 31 December 2014 the Tax Agency had a staff of 25,742 people, 1.86% fewer than in 2013, of whom 53.07% are women and 46.93% men, with an average age of 50.45 years (0.71 years more than in 2013).

The organisation of the Tax Agency bases its management on the high degree of specialisation and qualification of the professionals who compose it, in addition to intensive use of the new technologies.

The charts of the Annex set out below show the principal figures regarding the staff of the Tax Agency:

The performance of the Tax Agency's function of prevention and fight against tax and customs fraud is based on the work of its employees. A performance index has been developed to measure in average terms the contribution of each employee of the Tax Agency to the results of the fight against fraud, that is, the euros obtained in the fight against fraud, on average, by each employee. This is calculated via the Results/Staff ratio:

• The numerator consists of the revenues obtained every year in the fight against tax and customs fraud.

• The denominator consists of the total number of civil servants of the Tax Agency at 31 December of each year. It must be taken into account that, in addition to the fight against fraud, the Tax Agency's objectives also include information and assistance to taxpayers, collection management and customs procedures and surveillance.

In 2014, the Tax Agency had a budget of 1,322 million euros. The total cost amounted to 1,313.7 million euros, 0.04% more than in 2013.
