Concept
A Hong Kong private company must keep accounting records, prepare financial statements and, as a rule, have them audited by a practising CPA. The key exception is a formally dormant company: the Companies Registry states that an audit of financial statements is required for all companies, including those with reporting exemption, except dormant companies.
A company that simply did not trade but never declared dormant status keeps its audit and tax obligations. Formal dormant status is declared by special resolution filed with the Companies Registry — part of the obligations then falls away, but changes of directors, registered address and corporate details must still be reported.
What to close in a year
| Block | Practical meaning |
|---|---|
| Accounting records | bookkeeping of transactions, bank statements, invoices, contracts, expense support |
| Audit | review of the statements by a HKICPA practising CPA, unless the company is dormant |
| Profits Tax Return | tax return filed with the Inland Revenue Department together with financial statements and a tax computation |
| Annual Return | form NAR1 to the Companies Registry within 42 days of the incorporation anniversary |
| Bank compliance | the audit report and tax pack are often needed by the bank to keep the account running |
Deadlines
The Companies Registry expects the annual return of a private company within 42 days of the incorporation or re-domiciliation anniversary. The IRD track runs through the Profits Tax Return: it is issued in bulk around early April and is filed with supporting documents, financial statements and a tax computation. Companies with foreign-currency figures must restate the amounts in HKD and disclose the applied exchange rate.
The practical length of a full audit cycle is 6–10 weeks when documents are ready. If statements, invoices and contracts have to be reconstructed, the timeline easily becomes 2–3 months. A nil-activity company that is not formally dormant still needs an audit — a short nil audit runs about 5–7 business days once the absence of operations is confirmed.
Documents for the auditor
- bank statements for all accounts and currencies;
- invoices and receipts for key transactions;
- contracts with clients, suppliers and related parties;
- payroll, directors' remuneration, reimbursements and corporate cards;
- prior-year audit report and tax return;
- registers of directors, shareholders and significant controllers;
- documents supporting an offshore profits claim, if the company claims profits earned outside Hong Kong.
All documents are provided electronically — originals are not required.
What Triggers IRD Scrutiny
Hong Kong runs an "Assess First, Audit Later" system: returns are assessed as filed, and a computer-assisted selection then routes cases into desk audits, field audits or full investigations (DIPN 11). The published indicators that typically initiate a field audit or investigation are mechanical — and worth reading as a checklist of what not to resemble:
- a heavily qualified auditor's report on the accounts;
- unreasonably low turnover or profit margin for the nature and location of the business;
- persistent failure to lodge, or late lodgement of, tax returns;
- failure to keep proper business records (s.51C IRO — records must be kept for not less than 7 years after the transaction);
- failure to provide material information requested by the Department.
An offshore profits claim is a classic risk area: it is assessed as filed first and examined later. A routine investigation normally covers the six prior years of assessment (the s.60 window for back-year assessments); where fraud or wilful evasion is suspected, it extends to ten. Field auditors may visit the premises and issue s.51(4)(a) notices for books, records and third-party confirmations (DIPN 11).
Offshore profits claim
An offshore profits claim is not an automatic exemption. The IRD looks at where deals were concluded, where staff and directors worked, where management decisions were made, where clients and suppliers are located, how payments flowed and which documents evidence all of this.
If the company plans to file an offshore profits claim, the audit must be prepared in advance: correspondence, contracts, travel evidence, meeting minutes, shipping documents and the described business process must all match.
The Evidence File: Source, Substance, Audit
Three different layers of evidence are routinely confused. They answer three different questions, and the file must be built for each:
- Source evidence — where the profit-producing operations happened (DIPN 21: the broad guiding principle is "what the taxpayer did to earn the profit and where"). For trading, the place where purchase and sale contracts are effected is central: both outside Hong Kong points to non-taxable; one inside creates an initial presumption of full taxability; trading profits are not apportioned. Assessors ask for per-transaction travel, hotel and subsistence details when contracts are said to be concluded by travelling staff, and for agency agreements when overseas agents conclude them (DIPN 21, paras 23–26).
- Substance evidence — where directors and staff actually worked and decided: board minutes with place and attendees, travel records, office and payroll geography. This is what separates an operating company with offshore income from a Hong Kong desk with offshore paperwork.
- Audit evidence — the books and records behind the financial statements themselves: bank statements (including closed accounts), invoices, contracts, vouchers, registers. s.51C IRO requires them for at least 7 years; in a field audit the IRD examines them first and may reconcile them against third parties (DIPN 11).
Cost
Audit cost depends on annual company turnover and number of transactions. The rates below are for a standard financial year; a first company audit is typically 15–20% higher.
| Category | Cost |
|---|---|
| Dormant audit (no transactions) | €1,200 |
| Turnover up to $120K, up to 100 transactions | €3,200 |
| Turnover up to $120K, 100–200 transactions | €4,200 |
| Turnover up to $500K, up to 100 transactions | €5,200 |
| Turnover up to $500K, 100–200 transactions | €6,200 |
| Turnover up to $1,500K, 100–200 transactions | €7,500 – €8,500 |
| Turnover up to $2,500K, 100–200 transactions | €8,500 – €9,500 |
| Turnover above $2,500K or above 200 transactions | on request |
Timeline
- Nil audit — 5–7 business days from confirmation of no operations.
- Standard audit — 6–10 weeks depending on the volume and quality of documents provided.
- Rush audit before the IRD deadline — available with a 30% premium.
Cases from practice
HK trading company
The company buys goods in China and sells to the UAE. For the audit what matters is not only statements but contracts, invoices, logistics, the place of negotiations and an explanation of the margin.
Holding with a bank account
Few transactions, but the bank asks for the audit report, tax return and source-of-funds confirmation. A cheap “nil audit” does not work here if money moved across the account.
“A dormant company that had payments”
The client believed the company was dormant, but the account was used for intragroup transfers. First we restore the records and status, then prepare the audit and explanations for the IRD and the bank.
Who signs the report and who regulates it
Only a practising CPA — a HKICPA member with a valid practising certificate working through a registered practice unit — may sign a Hong Kong audit report. Since 1 October 2022 the profession has been regulated by the Accounting and Financial Reporting Council (AFRC): it issues practising certificates, registers auditors and practice units, conducts inspections and runs disciplinary proceedings; HKICPA still handles the registration of CPAs themselves. For a client this means one simple check before starting: the firm and the signatory must hold current statuses, otherwise the bank or the IRD will question the report.
Regulation and recent changes
The audit obligation follows from the Companies Ordinance (Cap. 622): the financial statements of a Hong Kong company are audited by a practising CPA, and there is no general exemption for small companies — the reporting exemption simplifies disclosures, but the audit itself remains.
Since 23 May 2025 Hong Kong has run a re-domiciliation regime: a foreign company can move its domicile to Hong Kong without liquidation and keep its legal identity. It must be deregistered in the original jurisdiction and confirm this to the Companies Registry within 120 days, otherwise the Hong Kong registration is revoked. After the move the company carries the same audit, annual return and Profits Tax Return duties as a local one — so the first Hong Kong audit often closes the transition year.
Profits of a Hong Kong corporation are taxed at two-tiered rates: 8.25% on the first HK$2 million of assessable profits and 16.5% above that. Audited statements underpin the tax computation in the Profits Tax Return. For groups under Pillar Two (the €750 million consolidated revenue threshold), the Hong Kong minimum top-up tax (HKMTT) applies from financial years beginning on or after 1 January 2025, and from the year of assessment 2025/26 the same groups must e-file their PTR: financial statements and the tax computation are tagged in iXBRL. The IRD plans to make e-filing fully mandatory by 2030 — Hong Kong filing is steadily going digital.
Common delays
- Missing statements for part of the period — banks issue them within 1–3 business days, but if the account is closed it may take up to a month.
- Mismatch between invoices and receipts — common after intragroup transfers; resolved by annotation or a retrospective agreement.
- Requests for additional information from the IRD after filing — these typically concern a tax exemption claim; we respond within 14 days.
Q/A
Does a nil-activity HK Ltd need an audit?
If the company is not formally registered as a dormant company, usually yes: it must keep records and close the tax loop. Properly declared dormant status grants the exception, but it cannot be replaced retroactively by the words “there were no operations”.
What is NAR1?
The Annual Return at the Companies Registry. For a private company the deadline is 42 days after the incorporation anniversary. It is a separate obligation from the tax return and the audit.
Can a Profits Tax Return be filed without an audit?
For an ordinary operating company, no: the IRD expects financial statements, a tax computation and supporting documents. The exact set depends on the return form and the company's status.
Why does the bank ask for the audit report?
For KYC and ongoing monitoring. The bank reconciles turnover, counterparties, source of funds and tax discipline. This matters even more for an international structure with owners outside Hong Kong.
Which documents prove offshore source?
The operations, not the labels: purchase and sale contracts and where they were effected, order correspondence, shipping and logistics documents, and — where staff concluded deals abroad — per-transaction travel, hotel and subsistence records; where overseas agents acted, the agency agreements (DIPN 21). The IRD reads these against where directors and staff actually worked, so the document set must match the management facts.
What does the IRD ask for in a field audit?
Books and records going back at least 7 years (s.51C IRO): accounts, vouchers, bank statements including closed accounts, invoices and contracts, plus details of the directors' current accounts. The process starts with an initial interview, can include a visit to the business premises and s.51(4)(a) notices to third parties such as banks and suppliers, and typically runs three to six months for a case of average complexity (DIPN 11).
