Publish how much motorists are paying in tax on petrol receipts, MP says Mr Halfon's campaign is backed by FairFuelUK, who have gathered over 15,000 signatures on a petition. Mr Halfon said: Less than one fifth of the money raised by motoring tax is actually spent on Britain's roads. At the moment, fuel duty is NOT shown on garage receipts. It is a stealth tax, and this is wrong. That's why I am calling for proper transparency on receipts. In the summer Chancellor George Osborne delayed a planned 3p increase in fuel duty from August 1 to January 1 next year after an outcry from motorists" groups. Mr Halfon added: "The Government [should also] scrap the 3p rise that is planned for January - as they did before. Petrol is expensive enough as it is. A Treasury spokesman said: "It is a commercial decision for individual petrol retailers to decide what information to provide in receipts. However, the Government has introduced targeted policies to improve transparency where it can within the personal tax system.
