3.3. Collection obtained from the activities of prevention and control of tax and customs fraud

The Tax Agency obtained 15,664 million euros in 2015 as a result of its work in the prevention and fight against fraud. This result represents a record figure that exceeds that achieved in the prior year by 27.2%.

In relation with this result, the Efficiency Index measures the amount obtained through these actions in the fight against fraud for each euro spent in the Agency. To calculate it, the following magnitudes are used:

The numerator includes, in millions of euros, the amount obtained through the fight against tax and customs fraud.
The denominator includes, in millions of euros, the amount of the annual budget of the Tax Agency, in terms of recognised obligations. It includes the cost of all the functions performed by the Tax Agency, since they all contribute to the fulfilment of its mission of ensuring the correct application of the State's tax and customs system.

According to the efficiency index, in 2015, for every euro spent by the Agency, 11.51 euros were collected in the fight against fraud.
