Why the Lagos Tax Filing Deadline Was Extended
The extension of the LIRS tax return deadline to April 14, 2026, is not just a random decision. It reflects ongoing efforts by the Lagos State government to improve tax compliance while giving taxpayers adequate time to file accurately.
Several factors influenced this extension:
However, make no mistake — this is not an excuse to delay further. Once the new deadline passes, enforcement becomes stricter and penalties begin to apply immediately.
Who Must File Tax Returns in Lagos?
One of the biggest misconceptions about Lagos income tax filing is that only business owners are required to file. This is incorrect.
According to LIRS, every taxable individual residing in Lagos must file annual tax returns, regardless of employment type.
Categories of People Required to File
Even if your employer deducts tax through PAYE, you are still required to file your annual return. PAYE is only an advance tax payment, not a substitute for filing.
Also, individuals with little or no income must still file what is called a nil return.
Common Mistakes Taxpayers Make (And How to Avoid Them)
Many people face penalties not because they refuse to pay tax, but because they make avoidable mistakes.
1. Declaring Only Salary
Most taxpayers only declare their salary and ignore side income such as:
This is a major compliance risk.
2. Waiting Until the Deadline
Late submissions often lead to:
3. Incomplete Documentation
Missing documents can delay or invalidate your filing.
4. Ignoring Relief Claims
Many taxpayers overpay simply because they fail to claim eligible deductions.
