Nigeria's tax reforms: what boards and CFOs should do now

Tax reform in Nigeria has moved from consultation to consequence. For most companies the difficulty is not understanding the headline changes — it is translating them into pricing decisions, contract terms, system configuration and board-level reporting before the first affected filing period closes.

Below is the readiness sequence we work through with finance leaders. It is deliberately ordered: each step depends on the one before it.

1. Fix accountability before interpretation

Most compliance failures we review are governance failures wearing a technical disguise. Decide, in writing, who owns each tax type, who signs off on positions taken, and who escalates uncertainty to the audit committee. Where a single tax manager silently owns interpretation, income tax, VAT and withholding positions, the organisation has concentration risk rather than a control.

A workable structure has three layers: preparation (finance operations), review (tax function or external adviser), and challenge (audit committee or board risk committee). Each layer needs a named owner and a documented calendar.

2. Test whether your data can support the positions you take

A tax position is only as defensible as the data behind it. Before rewriting policies, run a short diagnostic:

• Can you produce a transaction-level trail from the general ledger to each return, without manual reconciliation spreadsheets?
• Are customer and supplier master records complete enough to determine correct treatment automatically — jurisdiction, registration status, exemption flags?
• Do your ERP tax codes reflect current rules, or rules from the last configuration project?
• Can you reproduce a prior-period filing on request within a working day?

Where the answer is no, remediate the data before renegotiating the position. Authorities increasingly request source data, not summaries.

3. Re-price contracts deliberately, not implicitly

Changes to indirect tax and withholding treatment shift economics between parties. Review standard contract templates for tax gross-up clauses, change-in-law clauses and who bears the cost of a reclassification. In long-term service and infrastructure contracts, a treatment change absorbed silently by the supplier can erode an entire margin.

For each material contract, record three things: the assumed tax treatment at signature, the party bearing the risk of change, and the trigger for renegotiation.

4. Revisit transfer pricing documentation as a live document

Groups with related-party flows across borders should treat transfer pricing files as operational documents rather than annual artefacts. Two questions matter most: does the documented functional analysis still describe what people actually do, and does the benchmarking set still reflect current market conditions?

Where intra-group services, management fees or intellectual property licences carry material value, ensure the underlying evidence exists — timesheets, deliverables, board approvals — not only the policy that describes them.

5. Turn VAT and withholding recovery into a managed process

Recoverable input tax and creditable withholding are working capital. In our reviews the leakage is usually mundane: invoices that fail formal requirements, credit notes never processed, receipts filed but never claimed, or claims prepared after the statutory window closed.

Assign a single owner, set a monthly recovery review, and report unrecovered balances on the finance dashboard alongside receivables. Treated as a balance-sheet item, recovery improves quickly.

6. Build a defence file before you need one

Assume a review will happen. For each material position, keep a short memorandum: the facts, the rule relied upon, the alternative reading considered, and the reason for the conclusion. A three-page memorandum written contemporaneously is far more persuasive than a reconstruction produced under audit pressure two years later.

7. Report tax to the board in business terms

Boards need three numbers, not a technical briefing: effective tax rate and its drivers, cash tax outflow against forecast, and the value of unresolved exposures with a confidence range. Anything more granular belongs in the appendix.

Where this typically goes wrong

Three failure patterns recur. First, treating reform as a filing exercise, so systems and contracts are never updated. Second, over-reliance on a single individual's knowledge. Third, delaying remediation until an assessment arrives, when options have narrowed to negotiation.

Organisations that navigate reform well tend to be unremarkable in method: clear ownership, clean data, documented positions and early conversations with advisers before transactions are executed rather than after.

If you are working through this now, our tax practice supports Nigerian and multinational clients on compliance design, transfer pricing documentation, indirect tax recovery and dispute preparation.
