  1. A relevant tax authority may deregister or cancel a Tax Identification Number (TIN) in several circumstances. One clear circumstance is:
    When the business or taxpayer has permanently ceased operations.
    For example, if a company is formally dissolved, liquidated, or permanently closed, the tax authority may cancel the TIN because the entity is no longer carrying out taxable activities.
    Other circumstances may include:
    Death of an individual taxpayer where the TIN was issued to a natural person.
    Duplicate or wrongly issued TINs, where the authority cancels the extra or incorrect one.
    Merger or acquisition of companies, where the previous entity ceases to exist and a new entity continues the business.
    Discovery that the TIN was obtained fraudulently or with false information.
    Migration of a business to another tax jurisdiction where a new registration is required.

    In summary, a TIN is usually cancelled when the taxpayer no longer legally exists, no longer carries out taxable activities, or the registration was invalidly obtained.

  3. One circumstance is when a taxable person permanently ceases to carry on a trade or business in Nigeria. In such a case, the relevant tax authority may deregister or cancel the Tax Identification Number (Tax ID).

  4. A tax payer notifies the relevant authority of permanent cessation of business within 30 days, the authority thereafter confirms the cessation of business and then deregister or cancel the tax ID.

  5. By virtue of Section 10(5) (a) of the Nigeria Tax Administration Act 2025, one of the circumstance by which the relevant tax authority shall deregister or cancel a Tax ID is where it is satisfied that the taxable person is deceased, or, in the case of a body corporate,
    including a government ministry, department or agency is wound up or dissolved.

  6. The relevant tax authority shall deregister or cancel a Tax ID where it is satisfied that:
    (a) the taxable person is deceased, or, in the case of a body corporate, including a government ministry, department or agency, is wound up or dissolved; and
    (b) the person to whom the Tax ID was issued has another one.
    See Section 10(5) of the Nigeria Tax Administration Act, 2025.
    Furthermore, where a taxable person permanently ceases to carry on a trade or business in Nigeria, they must notify the relevant tax authority within 30 days of such cessation. Upon such notification, the relevant tax authority shall deregister the Tax ID. See Section 10(3)-(4) of the Nigeria Tax Administration Act, 2025.

  7. A circumstance when a tax authority shall deregister or cancel a Tax ID is when a person dies. This is because it becomes redundant. Another circumstance is when a company is wound up under CAMA 2020 or when a company formally informs a tax authority that they have ceased carrying on business.
