The Federal Inland Revenue Service (FIRS) has announced a temporary shutdown of its IT systems, affecting all applications and infrastructure from Friday, November 28, to Sunday, November 30, 2025.
“The general public should note that there will be an FIRS IT services downtime,” the agency said, apologizing for any inconvenience caused by the suspension of its applications and IT infrastructure.
The announcement follows a recent FIRS webinar clarifying corporate income tax changes for small companies. During the session, titled Income Taxes: Expected Changes in 2026 and How to Stay Compliant, FIRS officials explained that while small companies will not pay corporate income tax from 2026, they will still be required to compute taxable income and file self-assessment returns.
Deputy Director Kehinde Kajesomo clarified: “From 2026, small companies will pay tax, but at zero percent. Before, they were exempt from tax, but now they are liable to tax, though at zero percent. Companies will still compute taxable profits and file returns, but the tax payable will be zero.”
The new rules define small companies as those with an annual turnover of up to N50 million and fixed assets not exceeding N250 million. They will also pay zero percent tax on capital gains, a change from the previous 10 percent levy.
Meanwhile, multinational enterprises with global turnover above €750 million, and local companies exceeding N50 billion, will face a minimum effective tax rate of 15 percent under the Additional Tax Rule (ATR) of Section 57 of the Nigerian Tax Act.
FIRS also announced a new 4 percent Development Levy on accessible profits, replacing existing levies such as the Tertiary Education Tax, IT Levy, Police Trust Fund Levy, and NASENI Levy. The IT system downtime is expected to support these regulatory changes and ongoing system upgrades.
