Saudi CIT Bad Debts: Write-Offs, Evidence and Recoveries

Credit deterioration is not yet a tax write-off

An overdue invoice, an expected-credit-loss allowance and a debt written off as irrecoverable are different events. Saudi income-tax relief for an ordinary trade bad debt begins with Law Article 14 and Regulations Article 9(3), rather than the size of an accounting impairment. The conditions operate together; convincing evidence of financial distress cannot replace an omitted condition.

ZATCA’s Guideline on the Conditions of Deductible Expenses, second version May 2026, section 3.4, explains the rule and supporting evidence. Unlike some other sections, this section provides an evidence table rather than a numbered worked example. The numerical illustration below is Dariba’s own and is identified accordingly.

Trace the debt back to taxable revenue

The debt must arise from selling goods or providing services and have been declared in the return within the taxpayer’s revenues for the year the revenue became due. Reconcile the invoice to the sales ledger, original return and receivable balance. A capital contribution, deposit or loan principal is not brought within this trade-debt route merely because it is no longer recoverable.

This creates a useful review discipline: establish the origin of the debt before debating collection prospects. If the amount was never included as taxable revenue, first resolve that history. A ledger write-off cannot independently establish that the statutory prior-declaration condition was met.

Related-party debts fail a separate condition

Article 9(3)(e) requires that the debtor not be related to the taxpayer. Treat that as a standalone eligibility check rather than a documentation formality. A board-approved write-off and a debtor bankruptcy do not remove it. Review the applicable relationship facts and rules instead of relying only on how the customer was coded in the sales system.

Dariba’s advisory implication is that intercompany receivables should have their own tax review before settlement, waiver or write-off. This article does not prescribe an automatic deduction, dividend classification or withholding result for every related-party release. Those transactions require their actual legal character and relevant rules to be established separately.

Authorise the write-off and obtain the accountant’s certificate

Article 9(3)(c) requires a certificate from the taxpayer’s legal accountant confirming removal from the books pursuant to a decision by the authorised person. Section 3.4’s evidence table identifies the certified public accountant’s write-off certificate. An ageing report, management estimate or provision entry is not that certificate.

Retain the authorised decision, the debtor and invoice schedule, the actual ledger removal and the certificate tying them together. Where the receivable includes several invoices, distinguish the amount previously reported as revenue and the amount claimed. The tax file should demonstrate the written-off balance rather than leaving the reviewer to infer it from a net movement in a large allowance account.

Show the collection procedures and convincing evidence

Article 9(3)(d) requires the legal collection procedures and convincing evidence that collection is impossible. It names a judicial ruling and established debtor bankruptcy as examples. The guideline’s table follows that approach. Sending reminders or describing a customer as “unresponsive” does not, by itself, prove the complete test.

The examples of evidence are not a universal instruction that only one named document can ever suffice. Equally, commercial inconvenience is not a substitute for the required legal steps. For an unusual insolvency, foreign debtor or cost-sensitive recovery, document the actual procedures and resolve whether the evidence satisfies the provision before claiming relief.

Keep provision formation separate from qualifying utilisation

Law Article 15 restricts provisions, with specific banking treatment requiring its own conditions. Regulations Article 9(6) addresses use or reversal of previously added-back amounts. For an ordinary business, an accounting allowance is therefore not automatically deductible simply because it is based on a recognised financial-reporting model.

Where a previously disallowed provision is used against an actual trade debt, reconcile its tax history and the underlying bad-debt conditions. Do not deduct both the initial impairment and the subsequent write-off. Conversely, an accountant should not overlook an otherwise qualifying amount merely because the current income statement shows only provision utilisation rather than a fresh expense.

Bring a later recovery back into income

Article 9(3)(f) requires the taxpayer’s commitment to declare the debt in income when collected. Section 3.4 states that no particular document is prescribed for that commitment, while failure to recognise recovery can lead to an adjustment. Maintain a recovery flag in the debtor ledger after the write-off so cash received later is identified correctly.

Dariba illustration: assume a SAR 200,000 trade debt was previously declared and then validly deducted after all write-off conditions were met. A later SAR 30,000 recovery is included in income in the recovery year. The remaining unrecovered amount is SAR 170,000; it is not deducted a second time. This illustrates timing and duplicate-claim control, not ZATCA’s acceptance of a particular collection file.

Review the claim as a complete evidence chain

Before filing, reconcile the taxable revenue, unrelated debtor status, authorised decision, actual write-off, accountant’s certificate, legal collection history, impossibility evidence and recovery process. Identify any missing condition explicitly. A tax deduction should not be described as certain merely because six of seven documents appear persuasive.

The commercial value of this discipline is a clearer decision about the amount and year of relief, supported by a file that can be reviewed without reconstructing the debt’s history. Read the deductions guide for the wider computation. Banking doubtful-debt allowances and related-party waivers remain distinct analyses rather than exceptions inferred from this ordinary trade-debt rule.
