The 36 states of the federation, including the Federal Capital Territory, FCT, Internally Generated Revenue (IGR) declined by 11.7 per cent in the first half of the year to N612.87 billion.
This was contained in the states internally generated revenue report released by the National Bureau of Statistics (NBS) on Tuesday.
The report stated that this figure is lower when compared to N693.91 billion recorded in 2019.
“The 36 states and FCT IGR figure hits N612.87bn in H1 2020 compared to N693.91bn recorded in 2019. This indicates a negative growth of -11.7% year on year,” the report read.
The data was computed by the NBS in conjunction with the joint tax board headed by the Federal Inland Revenue Service (FIRS).
