Credit Note (Hong Kong)

A Credit Note in Hong Kong gives formal notice of the matter it concerns to the recipient.

Hong Kong businesses are assessed to profits tax under Part IV of the Inland Revenue Ordinance (Cap. 112), administered by the Inland Revenue Department (IRD). Section 51C of Cap. 112 requires every person carrying on a trade, profession, or business in Hong Kong to keep sufficient records of income, receipts, payments, and expenditure to enable the assessable profits to be readily ascertained. Credit notes form part of this audit trail — they document adjustments to previously recognised revenue and must be retained for at least seven years from the date of the transaction to which they relate, consistent with IRD practice under Cap. 112.

Hong Kong does not operate a goods and services tax (GST) or value added tax (VAT) regime, which means credit notes in Hong Kong do not carry the additional complexity of adjusting tax input credits or output tax that applies in jurisdictions such as Singapore (GST), the United Kingdom (VAT), or mainland China (增值税 / VAT). A Hong Kong credit note records only the commercial credit adjustment in Hong Kong dollars (HKD) without any tax components — a significant administrative simplification for businesses operating across multiple jurisdictions.

The Sale of Goods Ordinance (Cap. 26) governs the sale and supply of goods in Hong Kong, implying conditions as to satisfactory quality (Section 16), fitness for purpose (Section 16), and correspondence with description (Section 15). Where goods supplied fail to meet these implied conditions, the buyer has a statutory right to reject the goods and recover the purchase price — the seller's obligation to issue a credit note or refund arises directly from Cap. 26. For service transactions, the Supply of Services (Implied Terms) Ordinance (Cap. 457) implies terms of reasonable care and skill.

For consumer transactions, the Consumer Council of Hong Kong provides guidance on refund and credit note practices, and the Consumer Protection (Fair Trading) Ordinance (Cap. 456) prohibits unfair trade practices including refusing to issue credit notes or refunds for defective goods in circumstances where the consumer is legally entitled to them.

In commercial B2B transactions, credit notes should be numbered sequentially, reference the original invoice clearly, state the reason for the credit, and be authorised by an appropriate officer of the issuing business. The Inland Revenue Department may inspect credit notes during a profits tax audit to confirm that revenue adjustments are genuine and properly documented. Where credit notes are issued in bulk — such as year-end volume rebates — the IRD expects supporting documentation such as customer account statements and rebate calculation schedules.

A Credit Note in Hong Kong is required in six primary commercial situations, each with distinct accounting and legal implications under the Inland Revenue Ordinance (Cap. 112) and the Sale of Goods Ordinance (Cap. 26).

A seller must issue a credit note when a buyer returns goods that were previously invoiced and the seller accepts the return. The credit note cancels or reduces the original invoice to align the accounting records with the physical return of goods. Under Section 16 of the Sale of Goods Ordinance (Cap. 26), goods must be of satisfactory quality and fit for purpose — returned goods that fail these standards entitle the buyer to reject them and recover the price, triggering the seller's obligation to issue a credit note or refund.

A seller must issue a credit note when an invoice contains a billing error — an overstatement of price, an incorrect quantity, or an arithmetic mistake. The credit note corrects the discrepancy between the amount invoiced and the amount properly owed. The IRD expects accounting records to accurately reflect the true quantum of transactions; a correcting credit note is the appropriate mechanism rather than issuing a revised invoice with the same invoice number.

A seller must issue a credit note when a post-invoice discount, rebate, or price adjustment has been agreed with the buyer — for example, a retrospective volume rebate granted at year-end, a settlement discount for early payment, or a price reduction agreed to resolve a quality dispute. The credit note documents the reduction so that both parties' accounts payable and accounts receivable records reconcile.

A seller must issue a credit note when services invoiced have not been delivered — for example, an event that was cancelled, a subscription month that was not activated, or a project phase that was terminated before completion. The credit note cancels the obligation to pay for services not rendered.

A seller issuing a goodwill credit to a customer — to compensate for inconvenience, service disruption, or delivery delay — should document the credit with a formal credit note rather than an informal discount, to create a clear audit trail for the IRD and for the customer's accounts payable records.

When a business relationship terminates and the buyer holds an unused credit balance accumulated from prior credit notes, a final credit note or settlement should be issued to bring the accounts to zero. Unapplied credit balances on terminated accounts should be refunded rather than forfeited, as retaining them without entitlement may constitute unjust enrichment under Hong Kong common law.

A Credit Note for a Hong Kong business must include the following elements to satisfy IRD record-keeping requirements under Section 51C of the Inland Revenue Ordinance (Cap. 112) and provide clear commercial documentation.

Document Header and Identification must prominently display the words 'CREDIT NOTE' to distinguish the document from an invoice. The credit note number must be a unique sequential reference number in the seller's document series (for example, CN-2025-001). The date of issue must be stated in DD/MM/YYYY format consistent with Hong Kong commercial practice. A clear header prevents the buyer's accounts payable team from misclassifying the document as a new invoice.

Seller Details must state the seller's full legal name (or registered business name), registered business address, and Business Registration Number (BRN) issued by the Inland Revenue Department (IRD). For incorporated companies, the Companies Registry number under the Companies Ordinance (Cap. 622) may also be included to assist the buyer's supplier verification process.

Buyer Details must state the buyer's name and billing address. For corporate buyers, the company registration number and accounts payable contact assist processing and reduce the risk of the credit note being misdirected.

Reference to Original Invoice must clearly state the invoice number and date of the invoice being credited or adjusted. Without this reference, the credit note cannot be matched to the correct open item in the buyer's accounts payable system and will be held or delayed by the buyer's finance team pending clarification.

Reason for Credit must provide a plain-language explanation of why the credit is being issued — for example: 'Return of 10 units of Product X — goods not of satisfactory quality per Sale of Goods Ordinance (Cap. 26) Section 16'; 'Correction of pricing error on Invoice INV-2025-050'; or 'Agreed volume rebate for Q4 2025 purchases'. The IRD may request supporting evidence for the stated reason during a profits tax audit.

Itemised Credit Details must list each item being credited with the quantity, unit price in HKD, and credit amount. The presentation should mirror the layout of the original invoice to allow efficient matching. Hong Kong has no GST or VAT, so there are no tax line items to include or adjust — a simplification compared to jurisdictions operating a VAT system.

Total Credit Amount must be clearly stated in Hong Kong dollars (HKD). The credit note should state whether the credit will be applied against future invoices or refunded by bank transfer, and if by bank transfer, the timeline within which the refund will be made.

Authorised Signatory confirms the credit note has been approved by a person authorised by the seller to issue adjustments. For companies, this is typically the finance manager, CFO, or a director. The signature (or electronic approval under the Electronic Transactions Ordinance (Cap. 553)) creates an internal control record that satisfies IRD audit requirements under Cap. 112.

Retention and Record-Keeping: Both the seller and the buyer must retain credit notes for at least seven years from the relevant transaction date under Section 51C of the Inland Revenue Ordinance (Cap. 112). For electronic credit notes, the storage format must allow the document to be retrieved and printed for IRD inspection if required. Electronic records are recognised as valid under the Electronic Transactions Ordinance (Cap. 553).
