Introduction
Nigeria’s withholding tax (WHT) regime has undergone its most significant reform in decades and that reform is now fully operative. The Deduction of Tax at Source (Withholding) Regulations 2024 took effect in January 2025 while the 2025 Tax Reform Acts, which include the Nigeria Tax Act (NTA), the Nigeria Tax Administration Act (NTAA), the Nigeria Revenue Service (Establishment) Act (NRSA) and the Joint Revenue Board (Establishment) Act (JRBA), took effect in January 2026.
Businesses operating in or transacting with Nigeria are subject to this framework in full. There is no transitional period to anticipate. Contracts, intercompany arrangements, treaty structures and compliance systems that were adequate under the old regime are now being tested against rules that are actively enforced, with administrative penalties, compound interest and criminal liability attached. Businesses that have not yet aligned their systems and structures with the new framework are already exposed.
Key Changes under the 2025 Tax Reform Acts
The NTA consolidates several existing tax statutes into a single framework, repealing the Companies Income Tax Act, Personal Income Tax Act, Petroleum Profits Tax Act, Capital Gains Tax Act and Value Added Tax Act. The reforms simplify administration, expand the tax base, strengthen enforcement and align Nigeria’s WHT system with international standards.
The NTA has introduced expanded definitions with direct WHT implications. “Interest” now expressly covers penal charges, foreign exchange differences on debt, finance costs in lease arrangements and derivative-linked payments. “Dividend” extends to distributions on liquidation. “Royalties” is defined to include payments for the use of software, patents, trademarks, copyright and industrial or scientific equipment, capturing arrangements that previously occupied a grey area.
For non-residents, the position is now clear: WHT deducted on dividends, interest, rent, royalties, directors’ fees and payments to entertainers is the final tax, unless the recipient has a taxable presence in Nigeria. A separate 4% minimum tax on Nigerian-generated gross income applies where no WHT mechanism exists.
The NTA also provides targeted reliefs. Dividends received after WHT deduction constitute franked investment income and are not subject to further tax. Non-resident companies providing technical, consulting or management services to a labelled startup under the Nigeria Startup Act 2022 are subject to a reduced 5% WHT as their final tax.
The NTAA has introduced uniform procedures for assessment, filing, audit and enforcement across all tax types. The NRSA replaces the Federal Inland Revenue Service with the Nigeria Revenue Service, while the JRBA establishes a Tax Ombuds and reconstitutes the dispute resolution framework.
Double Tax Treaties and Beneficial Ownership
Nigeria’s double tax treaties (DTTs) continue to reduce WHT exposure on cross-border payments. The NTA confirms that all extant DTTs remain in force and expressly prohibits treaty-shopping arrangements aimed at securing benefits for residents of non-treaty countries.
The NTA now requires beneficial ownership as a condition for treaty access. A non-resident may only benefit from a DTT where it is the true beneficial owner of the income. Organizations relying on treaty structures must ensure that the recipient entity has genuine economic substance and is not a conduit established primarily to access reduced rates. Businesses may seek binding confirmation from the Nigeria Revenue Service within 21 days on specific WHT classification or treaty questions.
The WHT Regulations 2024: Position and Key Provisions
The 2024 Regulations replaced all prior WHT rules and are read together with the 2025 Acts. Several provisions carry specific practical weight.
The old “ordinary course of business” exemption has been replaced by a defined “across-the-counter transaction” exemption covering instant-payment transactions with no prior contractual arrangement. This is a narrower concept and the old exemption’s scope does not survive.
The Regulations introduce distinct timing rules. For third-party transactions, WHT arises at the earlier of payment or settlement. For related-party transactions, it arises at the earlier of payment or recognition of liability, which is directly relevant to intra-group service and financing arrangements.
Where a recipient has no Tax Identification Number, the applicable WHT rate is doubled on supplies of goods, services and other non-passive income transactions. Non-residents earning Nigerian-source income should register with the Nigeria Revenue Service to avoid this exposure.
Several income streams are now subject to WHT under the First Schedule: lottery and gaming winnings, compensation for loss of employment and fees paid to non-resident entertainers and sportspersons. Winnings from reality shows designed exclusively to promote entrepreneurship, academics or scientific innovation remain exempt.
On unremitted WHT, a supplier may claim WHT credit once a receipt is issued regardless of whether the deducting party has remitted (Regulation 8(3)). Non-remittance by the deducting party attracts the outstanding amount, a 10% per annum administrative penalty, interest at the CBN Monetary Policy Rate and a term of imprisonment up to three years upon conviction.
Implications for Businesses
The new framework is not prospective. Businesses that have not updated their accounting systems, ERP platforms, payroll systems and vendor management processes are accumulating live exposure. The NTAA empowers the Nigeria Revenue Service to distrain assets without a court order, appoint third-party agents to recover tax from funds held on a defaulter’s behalf and to conduct investigations and arrests through relevant law enforcement agencies. The six-year assessment window potentially keeps WHT exposures from 2020 onward within review scope.
Multinational groups must review intercompany financing, service agreements and intellectual property arrangements against the expanded definitions of interest, dividends and royalties and the formal beneficial ownership requirements now attached to treaty access. Where uncertainty exists on classification, advance rulings under the NTAA provide a structured route to certainty.
Conclusion
Nigeria’s WHT reforms have established a broader, more enforceable and internationally aligned framework. Both the 2024 Regulations and the 2025 Tax Reform Acts are operative. The priority for businesses is no longer preparation; it is remediation of existing gaps and sustained compliance under a fully active enforcement regime where the cost of non-compliance has materially increased.
