Nigeria’s fiscal landscape is shifting as the Federal Inland Revenue Service (FIRS) introduces a 10% withholding tax (WHT) on interest earned from short-term securities — a move aimed at expanding the country’s tax base and boosting government revenue.
The new directive, issued through a recent FIRS circular, mandates banks, brokers, discount houses, and other paying agents to deduct 10% WHT on all interest payments from short-term instruments such as treasury bills, corporate bonds, promissory notes, and bills of exchange. The policy takes immediate effect, ending a decade-long tax holiday on such instruments.
The Policy Shift and Its Background
Nigeria’s exemption on interest earned from bonds and short-term government securities was first granted in 2011 through the Companies Income Tax (Exemption of Bonds and Short-Term Government Securities) Order. The measure was designed to stimulate the domestic bond market and attract investment into government and corporate debt instruments.
That 10-year exemption period officially lapsed on January 2, 2022. With the expiry, FIRS has now clarified that all interest income on these instruments is fully taxable under the country’s tax laws — subject to a flat 10% withholding tax rate, consistent with what applies to dividends and rental income.
Impact on Investors and Businesses
For investors, this change means that interest income from short-term securities will now be reduced by the 10% tax deduction at source, lowering their net returns. Financial institutions, including banks and brokers, are now responsible for ensuring compliance — deducting, remitting the tax to FIRS, and issuing tax credit certificates to investors.
Analysts predict that the change could alter investment behaviour in Nigeria’s money market. Some investors may shift towards longer-term or exempt federal government bonds that continue to enjoy tax-free status. For corporate entities that rely on short-term debt for liquidity management, the policy will likely increase their after-tax financing costs, prompting adjustments in treasury and pricing strategies.
Exceptions and Clarifications
Not all instruments will be affected. Certain federal government bonds, particularly those explicitly listed as tax-exempt, will remain free of withholding tax.
For resident investors, the WHT serves as a credit against their final tax obligations, while for non-resident investors, the 10% rate applies unless reduced under double taxation treaties.
Expert Reactions and Economic Implications
Tax analysts and economists see this as part of Nigeria’s broader fiscal reform strategy under the current administration’s drive to improve non-oil revenue collection. The new measure could generate significant inflows for the government; however, experts warn that proper communication and system readiness are crucial to preventing market distortions.
According to market watchers, the adjustment may slightly compress yields in the fixed-income market, prompting investors to diversify their portfolios. However, in the long run, the policy is expected to strengthen compliance and transparency within Nigeria’s financial ecosystem.
As the FIRS steps up enforcement, investors and businesses alike must recalibrate their tax planning and investment strategies to adapt to Nigeria’s evolving fiscal realities.
