The Federal Inland Revenue Service (FIRS) has announced a temporary shutdown of its information technology (IT) systems, affecting all online applications and infrastructure. The downtime, scheduled to run from Friday, November 28, to Sunday, November 30, 2025, is aimed at carrying out essential maintenance and system upgrades. The agency has apologized for any inconvenience this may cause to taxpayers and businesses.
In a statement issued on Thursday, FIRS emphasized that all IT services, including tax filing and self-assessment platforms, will be unavailable during this period. “The general public should note that there will be an FIRS IT services downtime,” the agency said. This precautionary measure is expected to enhance the performance and security of FIRS digital systems.
The IT shutdown comes just two days after FIRS hosted a webinar clarifying upcoming corporate income tax changes for small companies. Deputy Director Kehinde Kajesomo explained that while small companies will pay zero percent corporate income tax from 2026, they are still required to compute taxable income and file self-assessment returns. “Before, small companies were exempt, but now they are liable to tax at zero percent,” Kajesomo said.
Under the revised rules, small companies are defined as firms with an annual turnover of up to N50 million and fixed assets not exceeding N250 million. These businesses will also pay zero percent tax on capital gains, down from the previous 10 percent rate. Meanwhile, multinational enterprises with global turnover above €750 million and local companies with turnover exceeding N50 billion will face a minimum effective tax rate of 15 percent under the Additional Tax Rule.
In addition to these tax reforms, FIRS plans to introduce a new Development Levy of 4 percent on accessible profits, replacing existing levies such as the Tertiary Education Tax, IT Levy, Police Trust Fund Levy, and NASENI Levy. Officials say the IT maintenance will ensure that the agency’s systems are fully prepared to handle these changes, reinforcing compliance and accurate reporting across all company sizes.
