The deadline for filing individual annual income tax returns for residents of Lagos State has again been extended to April 21, 2026.
This information was revealed via a statement signed by the Head of Corporate Communications of the Lagos State Internal Revenue Service (LIRS), Mrs Monsurat Amasa-Oyelude, on Saturday.
The agency thanked some taxpayers for their continued compliance and commitment to the filing of their individual annual income tax returns, but charged those who have yet to file theirs to do so before the new deadline.
LIRS had earlier moved the deadline from its statutory period of March 31, 2026, to April 14, 2026, but due to “the overwhelming response and to enhance taxpayer convenience, while maintaining the integrity and accuracy of submissions,” the date was moved forward to April 26.
The tax-collecting organisation said it “observed a significant increase in traffic on its eTax platform as more taxpayers endeavour to meet the filing deadline.”
“In view of this development, and to ensure that all taxpayers are provided with adequate opportunity to successfully complete their filings, LIRS hereby announces a further extension of the deadline, now set for April 21, 2026,” it stated.
The agency reiterated that all filings must be completed electronically via the LIRS eTax platform: https://etax.lirs.net, which remains the only approved channel for submission.
Taxpayers were reminded that the filing of annual income tax returns remains a statutory obligation and were encouraged to take advantage of this final extension to fulfil their civic responsibility.
