The 36 states of the federation grew their combined Internally Generated Revenue (IGR) by N360 billion in two years.
They grew the IGR from N1.31 trillion in 2019 to N1.67 trillion in 2021.
Chairman of the Nigeria Governors Forum (NGF), Governor Kayode Fayemi of Ekiti made the declaration in Abuja on Monday at the 8th IGR Peer Learning Event and launch of the NGF public finance database.
He said the share of IGR in total recurrent revenue of the states also rose from 31 per cent in 2019 to 35 per cent in 2021.
Fayemi attributed the improvement to the conscious reforms in tax administration in the states.
“Consensus reforms were focused on ending multiple taxations; professionalising and modernising our revenue services; embracing a taxpayer-centric culture that eases compliance and strengthens the existing social contract.
“What we need to do better is to foster an enabling tax environment and administration that allows us to optimise our revenue potential as sub-nationals.
“Our pursuit to do things differently has benefitted from the relentless efforts of our state officials, technical assistance programmes within our Secretariat and from partners’ support,’’ he said.
Fayemi added that collaborations and support had ensured that states stayed on the course of implementation, delivering far-reaching reforms, which yielded the results.
He said, however, that state governments must occasionally respond to the fast-changing tax environment if they must stay ahead of evasion and avoidance tactics.
