How to file tax on the LIRS eTax portal

Lagos State's Internal Revenue Service (LIRS) has extended its annual personal income tax filing deadline to April 14, 2025, signaling a critical shift in Nigeria's tax administration that European investors operating in West Africa cannot ignore. While the extension appears procedural, it reflects deeper structural changes in how Lagos—Africa's largest financial hub and home to thousands of European business operations—is modernizing its tax collection infrastructure and enforcement mechanisms.

The move to the LIRS eTax portal represents Lagos State's digitalization of a previously fragmented tax system. For European entrepreneurs and investors, this modernization carries dual implications: improved transparency and predictability in the business environment, but also heightened visibility and compliance scrutiny that many foreign operators have historically avoided.

Under Nigeria's Tax Act 2025, the definition of taxable income has expanded significantly. Passive income streams—rental yields, dividend distributions, and capital gains—now fall under mandatory reporting requirements. For European investors holding real estate portfolios in Lagos, or those with equity stakes in Nigerian enterprises, this expansion directly increases their tax liability. Previously, many foreign investors exploited definitional ambiguities around "resident income" and "foreign-sourced income." That loophole is closing.

The LIRS eTax portal mandatory filing requirement applies to any individual earning above ₦100,000 annually (approximately €130), which effectively captures all but the smallest foreign operations. More significantly, the portal integrates with Nigeria's Tax Identification Number (TIN) database and cross-references bank transaction data. This technological integration means tax evasion—which was endemic and largely tolerated under the old manual system—now carries genuine enforcement risk. Lagos State has explicitly announced penalties ranging from 10-50% of unpaid taxes plus criminal prosecution for willful non-compliance.

For European firms with Nigerian subsidiaries or local partnerships, the implications are material. Dividend repatriation, which many European parent companies undertake quarterly or annually, will now face automated scrutiny. Transfer pricing documentation—historically loosely enforced in Nigeria—will increasingly be challenged by a digitalized LIRS with improved audit capacity. Companies operating in sectors like telecommunications, oil services, fintech, and real estate should expect elevated tax audits through 2025-2026.

The April 14 deadline extension also signals that LIRS anticipates significant taxpayer resistance. Low voluntary compliance rates in Nigeria's informal economy have historically been tolerated by authorities. The shift toward mandatory digital filing suggests Lagos is attempting to formalize the tax base ahead of anticipated economic pressures—possibly driven by falling oil revenues or fiscal pressures at the state level.

Strategically, this tax modernization should be read as part of Lagos State's broader effort to professionalize its investment environment. Governor Babajide Sanwo-Olu's administration is positioning Lagos as a premium African financial center competing directly with Johannesburg and Kenya. Tax compliance and transparent fiscal administration are prerequisites for multinational capital inflows. For European investors, this is ultimately positive long-term—a more predictable, rule-based tax environment reduces political risk and supports asset valuations.

However, the near-term impact is clear: foreign investors must immediately audit their Nigerian tax positions, formalize previously informal income streams, and ensure full compliance with the eTax portal by the April 14 deadline. The cost of remediation now is far lower than the cost of penalties and reputational damage later.
