CHENNAI: Just as consumers are struggling to meet the DBTL mandate, Oil companies have released Form 5 which allows for voluntarily giving up subsidy on domestic Liquefied Petroleum Gas (LPG) cylinders. Consumers who are willing to forego the `500-plus subsidy per LPG cylinder can fill Form 5 and submit it to the gas agencies. Presently many senior officials of the three public sector oil companies – Indian Oil, BharatGas and Hindustan Petroleum, have opted for a no-subsidy Liquefied Petroleum Gas supply.
