Getting your Tax Clearance Certificate Frequently asked questions about filing taxes on the LIRS eTax portal What Nigeria’s 2025 tax reform changed If you have been trying to figure out how to file taxes in Lagos, this guide covers everything you need. The Lagos State Internal Revenue Service (LIRS) eTax portal at etax.lirs.net is the only approved platform for filing your annual personal income tax return, with a deadline of April 14, 2026. Every Lagos resident earning income must file, including salaried employees. Even if your company deducts PAYE from your salary every month and remits it to the government, you are still legally required to file your own individual return. Your employer’s payment does not cover your filing obligation. This is the first filing season under Nigeria’s sweeping 2025 tax reform laws, which introduced new tax bands, abolished the old Consolidated Relief Allowance, and made electronic filing the only acceptable method. Below is everything you need to know, from required documents and step-by-step portal navigation to exact penalty figures and post-filing steps. Why was the deadline moved to April 14? On March 31, 2026, LIRS Executive Chairman, Dr Ayodele Subair, announced a two-week extension of the individual annual income tax return deadline, pushing it from the statutory March 31 to April 14, 2026. The press statement, signed by Head of Corporate Communications, Monsurat Amasa-Oyelude, described it as a one-off measure to ease compliance and give taxpayers additional time to complete and submit accurate tax returns. The official statement did not mention portal problems. But Technext broke a story on March 30: the LIRS eTax portal at etax.lirs.net had experienced widespread technical difficulties just one day before the original deadline. Users reported hours of failed access attempts, submission errors, and an inability to complete filings. One user noted: “This is what’s expected of a platform likely designed for a few thousand users per day, suddenly needed to be accessed by millions.” Since manual filing has been completely phased out, taxpayers had no alternative. This was not an isolated event. Earlier in 2026, LIRS also extended the employer annual returns deadline from February 1 to February 7, signalling a pattern of administrative flexibility under the new tax regime. LIRS described the extension as a one-off measure. After April 14, penalties under the Nigeria Tax Administration Act (NTAA) 2025 kick in: N100,000 for the first month of default, plus N50,000 for each subsequent month. What counts as “income” under the Nigeria Tax Act 2025? The NTA 2025 defines ‘income’ broadly. Section 4 of the Act spells out every category of income, profits, or gains that are chargeable to tax. The law does not limit income to your salary or your business profit. It captures almost every way money can come to you. Here is what counts as taxable income: Employment income — your salary, wages, fees, allowances, bonuses, commissions, gratuity, and any other benefit your employer gives you, including things like a company car or rent-free accommodation Business and trade income — profit from any trade, business, or commercial activity. This includes selling perfume from home, baking and selling food, running a logistics operation from your phone, or any buying-and-selling activity, no matter how small Professional income — fees earned from professional services. This applies to lawyers, doctors, consultants, photographers, makeup artists, event planners, and any person who earns money by rendering a service Investment income — interest from savings accounts, dividends from shares, rent collected from property you own, and royalties Digital and virtual asset gains — profit from buying and selling crypto, NFTs, or any other digital asset Other sources — prizes, winnings, honoraria, grants, awards, discounts, rebates, and income from selling personal property or fixed assets The threshold is N800,000 per year. If your total income from all the sources above is N800,000 or less annually, your tax is 0%. But you are still required to file a return. Who needs to file taxes in Lagos? One of the biggest misconceptions in Nigerian tax compliance is the belief that salaried employees whose employers deduct Pay-As-You-Earn (PAYE) tax do not need to file annual returns. This is wrong. Section 14(3) of the NTAA 2025 explicitly resolves a long-standing ambiguity in the old Personal Income Tax Act: employees must file their own annual returns of income from all sources, notwithstanding the employer’s separate filing obligation under Section 14(1)-(2). LIRS has stated this directly: “Filing annual tax returns is not optional; it is a legal requirement under the NTAA 2025. While many employees believe their tax obligations end with PAYE deductions by employers, the LIRS clarifies that individuals must still file returns.” Taiwo Oyedele, Minister of State for Finance and Chairman of the Presidential Fiscal Policy and Tax Reforms Committee, reinforced the point, noting that “the tax reforms clarify that employees cannot assume their obligations end once employers deduct taxes from their salaries.” Here are the categories of people legally required to file taxes in Lagos, under Section 13 of the NTAA 2025: Salaried/PAYE employees – Even if your employer already files PAYE returns and deducts tax monthly, you must file an individual annual return declaring all income sources. This includes your salary, any side businesses, freelance work, rental income, and dividends. Self-employed individuals, freelancers, and gig workers – This includes digital creators, consultants, and anyone earning from online platforms. The NTA 2025 expressly brings digital/virtual asset gains, prizes, honoraria, and nontraditional income into the tax net. Business owners – Sole proprietors file as individuals under personal income tax. Partnerships are addressed under Section 15 of the NTA 2025. Professionals – Lawyers, doctors, accountants,
