AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Section 4 of the Nigeria Tax Administration Act 2025 requires every taxable person to register with the relevant tax authority and obtain a Taxpayer Identification (Tax ID), and section 8 requires banks, insurers, stockbrokers and other financial institutions to make a Tax ID a precondition for opening or operating an account. A person may hold only one Tax ID, and failing to register costs ₦50,000 for the first month and ₦25,000 for each month after.

| Issue | The authority registers and issues a Tax ID on request; a refusal must be explained within five working days | s.7(1)-(2) |
| Registration without application | The authority may register a person who should have applied, and must tell them | s.7(3)-(4) |

Who issues it and where the data sits
The Nigeria Revenue Service issues taxpayer identification in collaboration with state and local tax authorities and the Joint Revenue Board (NRS Act s.4(1)(q)). The Joint Revenue Board keeps an integrated database of taxpayer identification numbers for every taxable person in Nigeria (JRB Act s.5(a)). The NRS website links to a Tax ID portal at taxid.nrs.gov.ng and a Tax ID validation page.
The Acts use "Tax ID" throughout and define it by reference to the Administration Act. They do not state that any other identifier, such as a national identification number or a CAC registration number, is itself the Tax ID; check the NRS portal for how individuals and businesses are matched. For a step-by-step guide for companies, see how to get a Tax ID for your business. For the authority itself, see the NRS explained.
What changes, deregistration and suspension involve
Section 9(2) spells out the changes that must be reported within 30 days:
- name, including trading name, business location, phone numbers, email and registered address;
- for a company, anyone holding 5% or more of its shares, or the beneficial owner of shares held by nominees;
- for a trust, the identity and contact details of trustees and beneficiaries;
- for a partnership, the identity and contact details of all partners;
- for a sale, liquidation, acquisition, take-over or merger, all relevant information and details of the new owners.
If a business stops trading for a while, it notifies the authority within 30 days and its Tax ID is classified as dormant and suspended; on reapplication it gets the same ID back (s.10(1)-(2), (6)). A permanent cessation must also be notified within 30 days, and the authority deregisters the ID. It also cancels IDs of deceased persons, dissolved bodies and duplicates (s.10(5)).
Penalties
| Failure | Penalty | Section (NTAA) |
|---|---|---|
| Failing or refusing to register | ₦50,000 for the first month; ₦25,000 for each further month | s.100(1) |
| A statutory body or company awarding a contract to an unregistered person | ₦5,000,000 | s.100(2) |
| Not notifying a change of address within 30 days, giving a wrong address, or not notifying permanent cessation | ₦100,000 for the first month; ₦50,000 for each further month | s.112 |
Worked example (illustrative)
A trader starts selling on 1 March and registers on 15 July. Counting March to July as five months of failure, the penalty under section 100 would be ₦50,000 + 4 × ₦25,000 = ₦150,000. How the authority counts months in practice may differ, but the example shows how quickly the penalty adds up. Other penalties, such as for late returns, are listed in the tax penalties table.
A Tax ID also matters for documents. Section 8(1)(b) requires it on documents prepared or issued for a transaction, and section 152 of the Nigeria Tax Act requires the supplier's Tax ID on every VAT invoice. A business that issues invoices without its Tax ID risks both an invalid VAT invoice and questions from customers who need it to claim input VAT.
Where Pryme fits
Section 8(2) means a Nigerian bank or financial service provider will ask for your Tax ID when you open or operate an account. The rule applies to financial service providers generally, including Solid Allianze Microfinance Bank, which holds naira deposits for Pryme accounts. If you are asked for a Tax ID when opening or using an account, that request comes from the law. Account opening steps are on how it works.
How we put this together
We read the gazetted texts of the Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025 (Official Gazette No. 117, Vol. 112, dated 26 June 2025) section by section. The Nigeria Revenue Service website lists these Acts on its laws page, but its topic pages load in the browser and could not be read by our tools, so we worked from copies of the Gazette hosted by a third party and checked figures against the section and schedule numbers quoted here. Regulations, practice notes and orders issued after the Acts may change how a rule applies; where something depends on an order or regulation we say so. The Tax ID portal address comes from links in the NRS website's code; we did not test the portal. The example is ours.
