The cult rockers reformed to play Britain's Reading and Leeds festival after splitting in 2004, and were rumoured to have been paid $2.4 million (£1.5 million) for the two performances.
Doherty claims he and bandmate Carl Barat were in fact paid $384,000 (£240,000) each for the festival appearances, and insists there was little left from their paychecks after the costs of the shows had been covered.
Now he is hoping to receive $800,000 (£500,000) when they reunite for the British Summer Time Hyde Park event in July (14).
Doherty tells NME magazine, "Last time was supposed to be £240k each after tax for me and Carl. But by the time they paid for all the buses and s**t there was just a tax bill. This time I think we're getting half a million (£500,000) each, me and Biggles (Barat)."
