OCTIS vs how much a Hong Kong audit costs: online package or CPA firm
Published audit and tax prices for small companies, and what sets the fee.
Last checked · 6 sources
Otty's short answer
A small Hong Kong company can find published audit-and-tax packages from about HK$5,500 per year at Sleek or US$580 at Air Corporate. Osome does not publish an audit price, and independent CPA firms quote by scope. Every statutory audit must be signed by a practising CPA, so ask who signs, what is covered, and what raises the fee.

What the table does not show
Why an audit is required
The Companies Registry states that audit of financial statements is required for all Hong Kong companies, including those using the reporting exemption, except dormant companies. The Inland Revenue Department generally expects audited accounts with a company's profits tax return. The auditor should hold an HKICPA practising certificate. If the company never traded and passes a special resolution to be dormant, it can skip the audit.
What sets the fee
Sleek splits its audit-and-tax plans by size and complexity: Standard is for companies with assets below HK$10 million and no offshore tax arrangements, and Premium for larger or more complex ones. In practice, auditors price on transaction volume, quality of records, number of bank accounts, and how many questions the auditor must raise. Clean, reconciled books lower the fee. Late or missing records raise it.
Online package or independent CPA firm
A package gives a fixed price and a single place to upload documents, but the audit is still signed by a CPA practice behind the platform. An independent CPA firm gives you a direct line to the partner who signs the report. That matters when a bank, investor or overseas parent asks questions. Big firms add brand weight and cost. For a simple SME, a package or a small practice is usually enough.
Where OCTIS fits
OCTIS does not replace the statutory audit. A Hong Kong CPA practice signs it. What we do is keep your books clean and reconciled all year, prepare the statements and profits tax computation, and coordinate the audit so the fee stays predictable. If you already pay for audit and tax, send us your bill and we come in 10–30% off it.
Frequently asked questions
How much does an audit cost for a small Hong Kong company?
Published packages start around HK$5,500 per year at Sleek for companies with assets under HK$10 million, and from US$580 at Air Corporate. Larger or more complex companies, and firms that quote by scope, cost more.
Is an audit compulsory in Hong Kong?
Yes for all companies except dormant ones. Even companies using the reporting exemption must be audited. Sole proprietorships and partnerships are not covered by the Companies Ordinance audit rule.
Who can sign a Hong Kong audit report?
A practising certified public accountant, registered with the HKICPA and holding a practising certificate. Check the practice name and certificate number on the report.
Can the bookkeeper also be the auditor?
The auditor must be independent of the accounts they audit, so many companies use a separate CPA practice. Ask any provider how they separate the two roles.
Does a dormant company need an audit?
No. A dormant company can be exempt under section 447 after passing a special resolution and filing it with the Registrar. It still needs a secretary, annual return and business registration.
