The number of taxpayers stood at 14.1 million in May, a jump from 10.6 million at the end of 2008, indicating an increasing awareness of people to pay tax, according to the tax office.
The tax office has provided incentive and disincentives to taxpayers in order to attract new taxpayers, tax office chief Darmin Nasution said Monday.
The tax office has also conducted a "mapping, profiling and benchmarking" method to determine the amount of tax should be paid by taxpayers, he said.
Tax accounts for about 70 percent of total state revenue. Therefore the government strives hard to raise the amount of tax revenue.
