Energy needs of today's surveyors felt increasing. One of the agencies that are now being actively surveyor holding power is the Directorate General of Taxes. As a vital institution that sustains more than 70% of the financing needs of the country, the Directorate General of Taxation deems it necessary to optimize the revenue from the mining sector, especially of oil and gas. Given that the government has issued a total of 9000 permits the mining business, something that makes sense if the Directorate General of Taxation want the optimal revenue from this tax the mining sector. The use of an independent surveyor is expected to complement the existing system of tax collection. With the accuracy of the data from the Surveyor, the error reporting in the concept of self-assessment can be minimized. The involvement of agency surveyors can help provide information on production data, the number of export and production costs of the company mines. With accurate data, the government can control and monitor, so they can know the accurate amount of tax revenue from the mining sector. For that, as of 1 April 2012 the government in this case the Directorate General of Taxation Tax Office will operate in a deposit of Oil and Gas based in Jakarta. Establishment of this office aims to enhance the ability of tax officials in calculating taxes from oil and gas sector. Hopefully the government's desire to hold an independent surveyor could be realized, so the optimization of tax revenue from oil and gas sector better.
