With the March 31 deadline for Personal Income Tax (PIT) filing fast approaching, thousands of Nigerians are rushing to understand what compliance really means under the country’s evolving tax system.
From salaried workers to freelancers and small business owners, confusion is widespread. Many are unsure whether they are required to file returns, what documents are needed, and how to avoid penalties.

According to Innocent Ohagwa, president of the Chartered Institute of Taxation of Nigeria, filing tax returns is not optional. Speaking on national television, he stressed that compliance goes beyond revenue generation.
“Filing tax returns is a constitutional requirement, not a suggestion. It also gives citizens the moral right to demand accountability from government,” he said.
Who must file and why it matters
The March 31 deadline applies to all individuals under the Personal Income Tax system. This includes employees, self-employed professionals, and even those operating within the informal sector.
A common misconception is that Pay-As-You-Earn (PAYE) deductions settle all tax obligations. In reality, even individuals whose taxes are deducted at source must still file annual returns declaring their total income.
Tax authorities require a complete picture of earnings, regardless of how taxes were paid during the year.
Penalties: What happens if you miss the deadline
Failure to file returns on time comes with steep financial consequences.
Under the Nigeria Tax Administration Act 2025, defaulters face a penalty of N100,000 for the first month and N50,000 for each additional month of non-compliance.
Beyond fines, there are other risks:
- Automated audit triggers
- Interest charges tied to rates set by the Central Bank of Nigeria
- Possible tax investigations
For many taxpayers, especially freelancers and small business owners, these penalties are already a source of concern as the deadline draws closer.
How and where to file your returns
Taxpayers are expected to submit their returns through their respective state tax authorities.
For instance, residents in Lagos typically use the Lagos State Internal Revenue Service portal, while others file through platforms approved by the Joint Tax Board.
Key documents required include:
- Proof of income (salary slips, invoices, or bank records)
- PAYE summaries (if applicable)
- Tax Identification Number (TIN) or National Identification Number (NIN)
Errors or incomplete submissions can lead to penalties or delays, making accuracy just as important as meeting the deadline.
Confusion grows as new tax system rolls out
Nigeria’s tax reforms, led by Taiwo Oyedele and implemented through the Nigeria Revenue Service, are designed to improve transparency and expand the tax base.
However, the transition is not without challenges.
Tax expert Olatunji Abdulrazaq recently highlighted cases where taxpayers received overlapping audit and investigation notices for the same period, creating confusion and duplication of effort.
According to a BusinessDay report, many small business owners are also struggling to understand how newer systems, such as electronic invoicing, fit into their obligations.
E-invoicing and what it means for you
A nationwide electronic invoicing system is being introduced in phases:
- Large companies are already on board
- Medium-sized firms will join by July 2026
- Small businesses will follow by July 2027
While the system mainly targets VAT compliance, it does not replace the need for personal income tax filing. This means entrepreneurs may need to manage multiple reporting systems simultaneously.
Some mistakenly believe sending invoices via email qualifies as compliance, but authorities have clarified that formal filing remains mandatory.
Big revenue targets raise the stakes
Nigeria’s push for stricter compliance is tied to ambitious revenue goals.
In 2025, the country generated about N28.3 trillion in revenue, with non-oil taxes contributing a significant share. For 2026, the government is targeting N40.7 trillion.

According to Zacch Adedeji, the reforms are aimed at fairness, not increased burden.
“Our goal is to tax fairly, not more. Digital systems will simplify compliance and reduce leakages,” he said.
A critical test for Nigeria’s tax system
As the deadline approaches, both taxpayers and authorities are under pressure.
For individuals, the risk of penalties and audits is immediate. For the government, the challenge lies in handling a surge of filings while minimising confusion.
For many Nigerians, this moment represents the first real test of whether the country’s updated tax framework can deliver on its promise of transparency, efficiency, and fairness.
Tax ID rules: What Nigerians must know
Legit.ng earlier reported that the federal government has clarified that Tax Identification Numbers (TINs) are not required for strictly personal bank accounts under the new tax reforms.
TINs become mandatory only when an account is used for business transactions, the Presidential Committee on Fiscal Policy and Tax Reforms confirmed.
Chairman Taiwo Oyedele explained that authorities can detect business activity in personal accounts through Bank Verification Number (BVN) patterns, urging individuals to conduct self-assessment.
