Nigeria’s New Tax Rule Takes Effect: What Businesses and Taxpayers Need to Know
A new tax administration rule introduced by the Federal Government has taken effect across Nigeria, changing the way interest charged on late payment of taxes is determined.
The Nigeria Tax Administration Order 2026, signed by the Minister of Finance and Coordinating Minister of the Economy, Taiwo Oyedele, became effective on October 1, 2026.
The order concerns taxpayers who fail to pay their tax obligations when due and links the interest charged on outstanding tax payments more closely to prevailing market borrowing costs.

Under the new arrangement, the cost of delaying tax payments is tied more closely to market rates rather than being treated as an isolated administrative charge.
The Federal Government said the approach is intended to provide taxpayers with greater certainty about the financial consequences of late payment.
It also means that businesses and individuals with outstanding tax obligations need to pay closer attention to their filing and payment deadlines.

The order operates under Section 65 of the Nigeria Tax Administration Act, 2025, which provides the legal basis for interest on unpaid tax.
Why this matters to businesses
For small and medium-sized businesses already dealing with rising operating costs, delayed tax payments could create an additional financial burden.
A business that keeps money that should have been remitted as tax may now face interest charges that more closely reflect the cost of borrowing money in the market.
This makes proper tax planning and timely payment increasingly important for businesses.
What taxpayers should do

Taxpayers should:
Know the taxes they are required to pay.
Keep accurate financial and tax records.
Pay taxes before the applicable deadlines.
Confirm their tax obligations with the relevant tax authority.
Avoid assuming that delayed payment carries little financial consequence.
Seek professional tax advice where an obligation is unclear or disputed.
A bigger change is underway
The latest order comes as Nigeria continues to implement a broad restructuring of its tax system.
The Federal Government has also begun reviewing the implementation of the tax reforms, with officials saying the process is intended to identify gaps, clarify provisions and address unintended consequences.
In September, the government disclosed that it had received 134 stakeholder submissions as it began preparing the next phase of fiscal and tax reforms, including work toward the Finance Bill 2027 and revised tax regulations.
For ordinary Nigerians and businesses, however, the key issue is simple: tax obligations should no longer be treated as something that can safely be postponed.
As the new tax architecture takes shape, businesses will need to pay greater attention not only to how much tax they owe, but also to when it must be paid and what delaying payment could cost.
