Minister of Finance and Coordinating Minister of the Economy, Mr. Taiwo Oyedele, has issued the Nigeria Tax Administration (Interest on Late Payment of Tax) Order, 2026.
The Order sets the interest rate that applies when tax is not paid on time, as provided under section 65 of the Nigeria Tax Administration Act, 2025. It takes effect on October 1, 2026.
The Order links the cost of late payment more closely to market rates. It gives taxpayers certainty about what late payment costs, and together with applicable default penalty, it ensures that holding on to tax that is due is not cheaper than borrowing from the market.
What the Order provides
For tax payable in Naira, interest is charged at the Central Bank of Nigeria’s Monetary Policy Rate plus one percentage point. This is a reduction from the spread of five percentage point previously applicable but the rate will not fall below the yield on 364-day Treasury Bills, which reflects what it costs Government to fund itself when taxes are paid late.
For tax payable in foreign currency, interest is charged at the Secured Overnight Financing Rate (SOFR), the international benchmark for US dollar rates, plus six percentage points. If SOFR is discontinued, its official successor rate will apply.
One rate will apply for each calendar month.
The Nigeria Revenue Service, NRS, has been directed to publish the applicable rates on its website by the third business day of every month.

Speaking on the Order, the Minister said: “Tax that is due belongs to the public. When it is paid late, Government may have to borrow to fill the gap, and the cost falls on everyone. This Order ties the cost of late payment to real market rates, so that delaying tax does not become a cheaper form of credit than the market itself.”
He added: “Just as important is certainty. Every taxpayer, whether dealing with the Nigeria Revenue Service or a State revenue service, will know the rate in advance, see it published every month, and be charged in the same way. Clear rules make compliance easier and support a fair, predictable tax system.”
Transition and earlier notices
The new rates apply to interest arising from October 1, 2026, including interest on tax that became due before that date. Interest that arose before October 1, 2026, is not affected to the extent that it is specifically provided for under the rules in force at the time.
The Order supersedes the 2017 notice on interest on unpaid taxes and any other earlier notices on the subject.
The Order does not change the 10 percent penalty for late payment under section 65 of the Act. Relevant tax authorities also retain their power under section 66 of the Act to waive penalty or interest where good cause is shown.
Advice to taxpayers
Taxpayers are encouraged to file their returns and pay applicable taxes on time, and to check the monthly rates on the Nigeria Revenue Service website. Those with outstanding liabilities are advised to settle them promptly or engage the relevant tax authority.
