The Senate has queried the Central Bank of Nigeria over alleged unremitted $3.3bn from the $21.3bn collected by the Federal Inland Revenue Service as foreign tax in 2015.
The Public Accounts Committee of the red chamber issued the query after its meeting on Wednesday.
The Senate panel said it acted on an audit query raised against the CBN by the Office of the Auditor General for the Federation.
The panel quoting the audit query said while the FIRS recorded $21.3bn as the total sum of foreign tax collected by it in 2015 and domiciled in the apex bank, the CBN on the other hand, recorded $18bn.
The Chairman of the panel, Senator Mathew Urhoghide, asked the CBN management to explain the shortfall.
The Deputy Governor (Corporate Affairs) of the bank, Mr Edward Adamu, had given an explanation that was not convincing to the panel stating that the shortfall of $3.3bn was neither missing nor unremitted.
The Senate committee then directed him and other top officials of the CBN to report back to it on Monday with required documents on the alleged variations in the exchange rate.
