Receivables on the Balance Sheet Look Like Money. IFRS 9 Says: Prove It.

Receivables in financial statements are usually stated as current assets. But on closer inspection, they may not all be assets. Every trade receivable on a balance sheet represents a claim against a customer who has not yet paid. Whether that claim will ultimately be honoured is a question of credit risk — and IFRS 9 requires that question to be asked, and partially answered, on the very day the invoice is raised. Not when a customer defaults. Not when a debt is referred for collection. From day one.

This article sets out the IFRS 9 expected credit loss framework in practical terms: the two approaches, the mechanics of the provision matrix, the double-entry treatment at every stage of a receivable's life, and — critically — the point at which accounting and tax law part ways, and what that divergence means for Nigerian corporate reporters navigating the Nigeria Tax Act 2025.

1. The Fundamental Shift: From Incurred Loss to Expected Loss

Before IFRS 9, impairment was governed by IAS 39's incurred loss model. A business only recognised a bad debt provision once there was objective evidence that a loss had already occurred — a customer in default, a debtor in liquidation, a dispute escalated to litigation. Losses were recognised reactively, often long after the underlying credit deterioration had taken place.

IFRS 9 replaced this with a forward-looking expected credit loss model. The standard requires entities to recognise a loss allowance for credit losses that are expected to occur — not losses that have already been confirmed. This shift in thinking is the source of most of the confusion we encounter in client financial statements. A zero provision on a performing receivable is rarely correct under IFRS 9. The question is never whether a loss has occurred. The question is whether a loss is expected.

2. Two Approaches — and Knowing Which Applies to You

The General Three-Stage Model

The general approach applies to loans, bank deposits, intercompany receivables, and investments in debt instruments — instruments more typical of financial institutions than ordinary trading or service businesses. It tracks the migration of credit quality through three stages:

•       Stage 1 — Performing. No significant increase in credit risk (SICR) since initial recognition. The entity recognises 12-month expected credit losses — the portion of lifetime losses arising from default events possible within the next 12 months.

•       Stage 2 — Underperforming. A significant increase in credit risk has occurred since initial recognition. IFRS 9 includes a rebuttable presumption that SICR has occurred when payments are more than 30 days past due — but this is a presumption, not a hard rule. Other indicators such as deteriorating credit ratings, covenant breaches, or material changes in the debtor's financial position can trigger Stage 2 independently of the ageing. Once in Stage 2, the entity recognises lifetime expected credit losses.

•       Stage 3 — Credit-Impaired. Objective evidence of impairment exists. IFRS 9 includes a rebuttable presumption of impairment at 90 days past due, but again this is a presumption — not a bright-line rule. Other evidence of impairment includes significant financial difficulty of the debtor, breach of contract, high probability of bankruptcy, or grant of concession by the creditor. Lifetime ECL is recognised, and interest income is calculated on the net carrying amount rather than the gross amount.

The rebuttable nature of both the 30-day (Stage 2) and 90-day (Stage 3) presumptions matters in practice. A debtor that is 35 days past due because of a known, short-term processing delay — rather than credit deterioration — can remain in Stage 1 if the entity can support that position with reasonable and supportable information. Most Nigerian entities, however, do not maintain the documentation needed to rebut these presumptions, and in practice the ageing triggers are widely applied as working rules.

The Simplified Approach — What Most Nigerian Businesses Must Use

For trade receivables and contract assets that do not contain a significant financing component, IFRS 9 does not merely permit the simplified approach — it requires it. An entity recognises lifetime expected credit losses from the moment the receivable is first recognised, with no need to track stage migration or monitor for SICR. Lease receivables may also apply the simplified approach as an accounting policy election.

The practical effect for most Nigerian businesses — across trading, oil and gas services, construction, and professional services — is that the three-stage model is relevant only for loans and similar instruments. Trade receivables go straight to lifetime ECL from day one, and the provision matrix is the standard method of implementing that.

3. Building the Provision Matrix — A Worked Example

The provision matrix is the standard practical method of applying the simplified approach. It applies historical loss rates, adjusted for current conditions and forward-looking information, to an aged analysis of year-end trade receivables.

The construction involves four steps:

1.       Group receivables by shared credit risk characteristics — for example, customer type (government entity, multinational, SME, related party), currency of denomination, or geography. A single blended rate applied across a non-homogeneous book is not IFRS 9 compliant.

2.      Determine historical loss rates by ageing bucket, using at least 24 to 36 months of credit sales and write-off data.

3.      Adjust for current and forward-looking conditions — for example, anticipated currency pressure, sector-specific liquidity stress, or known deterioration in a major customer category. Document the basis for each adjustment explicitly; it must be reasonable and supportable, not an arbitrary buffer.

4.      Apply the adjusted rates to the year-end aged receivables balance.

Illustration — Rivers Hardware & Building Supplies Ltd.

Rivers Hardware is a Port Harcourt distribution company with trade receivables of ₦185,000,000 at 31 December 2025, extended to retail and wholesale customers on 60-day terms. Over 24 months, the company recorded total credit sales of ₦2,400,000,000 and confirmed write-offs of ₦36,000,000 — an overall historical loss rate of 1.5%. The matrix below shows how that base rate is analysed by ageing bucket and adjusted for the company's reasonable expectation of continued currency pressure on its wholesale customer base:

The colour gradient is deliberate and worth building into your own internal reporting — pale green at the top, deepening to red as receivables age. A finance director should be able to read the risk profile of the receivables book at a glance, without opening a spreadsheet.

The matrix produces a loss allowance of ₦9,250,000 against gross receivables of ₦185,000,000 — an effective coverage rate of 5.0%. The receivables that appeared as a ₦185 million asset on the pre-provision balance sheet are, after honest assessment, worth ₦175.75 million. IFRS 9 has done precisely what it was designed to do: converted a statement of what is owed into a statement of what is expected to be collected.

4. The Double-Entry Mechanics — Precision at Every Stage

Maintaining accounting integrity requires correct execution of three distinct types of entry across the life of a receivable. The loss allowance account is a contra-asset — it sits on the Statement of Financial Position as a deduction from gross trade receivables, never as a separate liability.

Scenario A — Recognising or Increasing the ECL Provision

Applying the matrix produces a closing allowance of ₦9,250,000 at 31 December 2025 against an opening allowance of nil:

Scenario B — Adjusting the Provision at the Next Reporting Date

At 31 December 2026, the recalculated matrix produces a required closing allowance of ₦11,400,000, against an opening allowance of ₦9,250,000. Only the movement is recognised:

Where the recalculated allowance is lower than the opening balance — for example, because large debts have been collected or the credit environment has improved — the entry reverses: debit the Allowance for ECL, credit Impairment Loss (a reversal gain in profit or loss).

Scenario C — Executing a Specific Write-Off

A customer enters insolvency. The company confirms ₦1,800,000 of the outstanding balance is unrecoverable. This debt is already covered within the ₦9,250,000 allowance:

This entry does not touch profit or loss. The loss was already recognised when the provision was raised. The write-off simply removes both the gross receivable and the corresponding slice of the allowance from the balance sheet simultaneously — the net carrying amount of receivables is unchanged. This is precisely the purpose of the ECL model: income statement impact happens proactively, not at the point of confirmed loss.

5. Sector-Specific Considerations

•       Oil and gas services — USD-denominated receivables. Counterparties are often well-capitalised multinational or national oil companies, and the generic ageing-based rates derived from a broad customer base should not be applied to these receivables without adjustment. Where a small number of large counterparties have demonstrably strong credit standing, a counterparty-specific assessment — grouped separately from weaker local subcontractor debtors — is more defensible. We frequently see Nigerian oilfield services companies either over-providing against investment-grade international receivables or under-providing against genuinely weaker local debtors, because a single undifferentiated matrix has been applied across a non-homogeneous book.

•       Construction and engineering — contract assets and retentions. Amounts earned but not yet billed under IFRS 15 (contract assets) fall within the same simplified ECL approach as trade receivables. Retention balances require a loss rate calibrated to the genuinely longer recovery horizon, rather than the shorter ageing buckets used for ordinary trade debtors.

•       Related party receivables. IFRS 9 does not exempt related party balances from ECL assessment. A receivable from a related party with no fixed repayment terms and no realistic expectation of timely settlement carries a higher effective credit risk than its nominal terms may suggest.

6. The Tax Divergence — NRS and the NTA 2025

Recognising an ECL provision is an accounting requirement. Whether the same provision reduces your taxable profit under the Nigeria Tax Act 2025 is a distinct legal question — and the two frameworks produce materially different answers.

General Provisions — Non-Deductible

The Nigeria Revenue Service, consistent with the position established under predecessor tax legislation and upheld by the Tax Appeal Tribunal in NPF Microfinance Bank Plc v. Federal Inland Revenue Service, treats statistical ECL provisions — including all matrix-derived allowances — as general provisions. Because these are based on probabilities and historical averages rather than specific, documented evidence of loss on identified debtors, they are non-deductible in the CIT computation. The entire ECL impairment charge must be added back to net profit in arriving at assessable profit under the NTA 2025.

This means that most companies applying the simplified approach will carry a timing difference between their IFRS profit and their taxable profit. This is not a compliance failure — it is the correct outcome of two frameworks that are measuring different things. What is essential is that the add-back is actually made. We continue to encounter Nigerian companies that deduct their full IFRS 9 ECL charge in arriving at taxable profit without adjustment — a position the NRS will identify on audit, with administrative penalty and interest consequences under the NTA 2025.

Specific Write-Offs — Potentially Deductible

For a bad debt deduction to be allowed under the NTA 2025, the following conditions must be substantiated:

•       The debt must be connected to the entity's trade or business.

•       The debt must have become entirely or partially worthless during the specific assessment year in which the deduction is claimed.

•       The entity must have exhausted all reasonable, documented legal and commercial recovery efforts — demand letters, formal collection engagement, evidence of debtor insolvency — without success.

Only when a specific debt is written off out of the books under these conditions, and with this level of documentation, can the deduction be successfully defended in an NRS audit. The general ECL provision converts into an allowable specific deduction only at the point that worthlessness is established and evidenced — not at the point the matrix provision was recognised.

Deferred Tax Asset — IAS 12 Implications

Because the timing of the accounting expense (ECL provision recognised through P&L) differs from the timing of the tax relief (specific write-off substantiated and allowed), a deductible temporary difference arises. The carrying amount of trade receivables on the IFRS balance sheet (gross receivables less the ECL allowance) is lower than the tax base of those receivables (which remains at the gross amount until an NRS-approved write-off is made).

Under IAS 12, this deductible temporary difference gives rise to a Deferred Tax Asset (DTA), measured at the applicable CIT rate. The DTA represents the future tax benefit the entity expects to obtain when the temporary difference reverses — i.e., when the specific debts are eventually written off and the deduction is recognised for tax purposes.

Recognition of the DTA is subject to the probability criterion in IAS 12: it may only be recognised to the extent that it is probable that sufficient future taxable profits will be available against which the temporary difference can be utilised. For a company with consistently profitable operations, this condition is normally met without difficulty. For an entity in a loss position or with limited visibility of future profitability, the DTA may need to be partially or fully derecognised — a judgment that must be reassessed at each reporting date.

7. IFRS 7 Disclosure Requirements

The ECL provision is not a note that can be reduced to a single line. IFRS 7 requires the following minimum disclosures:

•       A reconciliation of the opening to closing loss allowance balance, showing amounts recognised in P&L, amounts reversed, and amounts written off during the period

•       An analysis of trade receivables by ageing bucket, cross-referenced to the loss allowance recognised against each bucket

•       A description of the inputs, assumptions, and estimation techniques used, including how forward-looking information was incorporated

•       Information about significant concentrations of credit risk — for example, reliance on a small number of major customers, or a large exposure to a single sector

These disclosures are consistently incomplete in Nigerian financial statements reviewed for audit or for financing purposes. Incomplete IFRS 7 disclosure is, in itself, a departure from full IFRS compliance — independent of whether the ECL numbers themselves are correct.

8. Summary — IFRS 9 and the NTA 2025 Side by Side

Practical Next Steps

5.      Extract at least 24 to 36 months of credit sales and write-off history, analysed by ageing bucket at the point of write-off.

6.      Group your trade receivables by genuinely shared credit risk characteristics before constructing a matrix — not merely by department or product line.

7.      Build the provision matrix with historical loss rates and explicitly documented forward-looking adjustments, and apply it to the year-end aged receivables listing.

8.     Prepare the three journal entries — provision, movement, and write-off — as a standing part of your period-end close process.

9.      Add back the full ECL charge in your NRS tax computation, and recognise the resulting DTA under IAS 12 where the probability criterion is met.

10.  Maintain a separate specific write-off tracker, with documented evidence of recovery efforts, to support eventual tax deductions when specific debts are confirmed irrecoverable.

11.   Prepare a complete IFRS 7 disclosure note, including the allowance reconciliation and ageing analysis.

12.  Refresh the provision matrix at least annually — loss rates calibrated in a different economic environment will not reflect current credit risk.

The receivables balance on the face of your balance sheet is a statement of what is owed. The ECL allowance is the profession's honest answer to how much of that will actually be collected. The two numbers together — gross and net — tell readers what the financial statements are actually worth. Getting that answer right, and keeping it right, is the work.
