He also said the agency has a target of 10 million new taxpayers to bring the number to 20 million people.
About 700,000 firms that have never paid taxes are to be brought into the tax net as the country seeks new revenue sources to offset low oil prices that have pushed the economy into its first recession.
Fowler, in an interview with news agency, said: “We collected a little over N2.3 trillion, so far – from January to 31 August. It is almost at par with last year but take into consideration that the economy is going through a little slowdown.”
He said that the revenue from Value Added Tax (VAT) has increased by 25 per cent year-on-year and corporate income tax held steady over the same period but petroleum profit tax was expected to have halved, mainly due to low oil prices.
Fowler, Lagos’ former tax chief, who increased monthly tax revenues by 70 per cent within four years in the nation’s commercial capital, said a new unit created early in the year has deployed inspectors, armed with laptops to update databases, registering businesses and individuals, who are then tracked to check whether they have paid taxes.
“From our estimates, we expect that we have 60 million individuals who should pay some form or level of tax,” said Fowler.
He said tougher enforcement would be combined with a planned waiver on interest and penalties covering the period from 2012 to 2015 under which people and businesses would only be asked to pay the principal amount of tax liabilities due.
“We will give them a 45-day window to come forward and register and that will make them eligible for that waiver,” said Fowler of the proposal, which was submitted to the finance minister for approval.
He said: “A lot of people who are not in the tax net are a bit jittery or afraid to come and register, thinking that we might go back two or three years and the amounts might be considerable.”
But he warned that those who failed to register for the scheme – which he said could be rolled out as soon as October 3 – would face stiff penalties.
Individuals and businesses who did not come forward voluntarily would be asked to pay back taxes plus interest and penalties, he said.
“We will also consider criminal prosecution of chief executive officers or board members,” Fowler said.
He was cautious on the idea of an increase in the VAT rate which, at 5 per cent, is among the lowest in the world.
The government, struggling to fund a record N6.06 trillion (about $18.6 billion) 2016 Budget that aims to stimulate growth by tripling capital expenditure, set FIRS a target of raising N4.95 trillion in taxes, up from N3.73 trillion last year.
International Monetary Fund (IMF) Managing Director Ms. Christine Lagarde suggested a VAT rate hike when she visited the country in January and Vice President Yemi Osinbajo later said the government was considering tax regime changes to raise funds.
Fowler said it was part of the government’s remit to “take a decision” on VAT but he thought “the economy is not ready for a VAT increase right now”.
“The level of compliance was too low so that if we increased the rate of VAT it would be a punishment and unfair on those who are collecting and remitting VAT,” the tax chief said.
