According to RMFAC, in a statement, the sum includes the $15bn which the Accountant-General of the Federation, Ahmed Idris, had last week accused the NNPC of not paying in 2014 alone.
Oil revenue accounts for roughly two-thirds of the government’s funding.
“Records at the Commission’s disposal indicate that between January 2011 and December 2015, the total indebtedness of NNPC to the Federation Account was 4.9 trillion naira,” said RMAFC.
Under the current set-up, the NNPC hands over its oil revenue and money is then paid back based on a budget approved by parliament.
Last month, Minister of State for Petroleum Resources and Group Managing Director of NNPC, Ibe Kachikwu, announced that the NNPC would be broken up into seven different companies.
It would be recalled that a separate audit ordered under former President Goodluck Jonathan and carried out by global accountancy firm PwC, found that the NNPC had failed to pay the government $1.48bn between January 2012 and July 2013.
