Companies operating in Lagos State have been reminded of their obligations to file their annual tax returns for the 2025 financial year on or before January 31, 2026.
This reminder was given by the Lagos State Internal Revenue Service (LIRS) in a statement made available to Business Post on Thursday.
In the notice signed by the chairman of the tax agency, Mr Ayodele Subair, it was stressed that filing the tax returns is an obligation as stipulated in the Nigeria Tax Administration Act (NTAA) 2025.
He explained that employers are required to file detailed returns on emoluments and compensation paid to their employees, as well as payments made to their service providers, vendors and consultants, and to ensure that all applicable taxes due for the year 2025 are fully remitted.
Mr Subair emphasised that filing of annual returns is a mandatory legal obligation, and warned that failure to comply will result in statutory sanctions, including administrative penalties, as prescribed under the new tax law.
According to Section 14 of the NTAA, employers are required to file detailed annual returns of all emoluments paid to employees, including taxes deducted and remitted to relevant tax authorities. Such returns must be filed and submitted not later than January 31 each year.
“Employers must prioritise the timely filing of their annual income tax returns. Compliance should be part of our everyday business practice.
“Early and accurate filing not only ensures adherence to the law as required by the Nigerian Constitution, but also supports effective revenue tracking, which is important to Lagos State’s fiscal planning and sustainability,” he noted.
The LIRS chief disclosed that electronic filing via the organisation’s eTax platform remains the only approved and acceptable mode of filing, as manual submissions have been completely phased out. This measure, he said, is aimed at simplifying and standardising tax administration processes in the state.
Employers are therefore required to submit their annual tax returns exclusively through the LIRS eTax portal: https://etax.lirs.net.
Dr Subair described the channel as secure, user-friendly, accessible 24/7, and designed to provide employers with a convenient and efficient means of fulfilling their tax obligations, advising firms to ensure that the tax identification number (Tax ID) of all employees is correctly captured in their filings, noting that employees without a Tax ID must generate one promptly to avoid disruptions during the filing process.
