Taxing income earned through agricultural activities is the sole prerogative of provincial governments under the 1973 Constitution of Pakistan. All the four provinces have enacted laws to this effect, but total collection in 2009 was below Rs. 2 billion against the actual potential of Rs. 200 billion (share of agriculture in GDP was about 22 percent). This abysmally low collection proves beyond any doubt lack of political will to tax the rich absentee landlords. Presently, the provincial governments are not collecting tax on agriculture income but on fixed per acre basis. They charge Rs.150 per acre from the irrigated area and Rs100 per acre from non-irrigated land. This is gross violation of Constitution that requires tax on agricultural income.
