Every Hong Kong limited company has to hand in audited financial statements with its profits tax return, no matter how small the business is. For a company in its first year, that sentence alone is enough to cause a cold sweat: what exactly does an auditor need, how early should you start, and how do you stop the whole thing becoming more expensive than it needs to be?
This guide walks through what a first time audit in Hong Kong actually involves, what documents you should have ready before you even pick up the phone to an accountant, and the three places where first-year companies almost always get tripped up.
What “first audit” really means in Hong Kong
Under the Inland Revenue Ordinance section 51, every HK limited company must file a profits tax return (BIR51) together with audited financial statements, signed off by a HK-registered Certified Public Accountant (CPA). The Companies Ordinance separately requires every company to keep proper books and prepare statutory accounts each financial year.
The first return usually arrives in the post about 18 months after incorporation. That 18-month window catches a lot of founders off guard because it is longer than a normal year, which means the first set of audited accounts covers a period that might run from, say, 1 March 2025 to 31 March 2026 — 13 months, not 12. The period has to be closed, reconciled, and audited in one go.
Because the first-year accounts also set the opening balances that every future audit will roll forward from, the auditor will look harder at them than at any subsequent year. Getting it right the first time saves you money every year after that.
The first-audit document checklist
Before you contact an auditor, gather the following. If you can hand everything over in one clean folder, you will almost always get a lower fee quote.
- Incorporation documents. Certificate of Incorporation, Business Registration Certificate, Articles of Association, Form NNC1, any Form NAR1 filed to date, and the register of members and directors.
- Bank statements for every account, every month. Cover the entire period from incorporation date to year-end. Do not skip the months with no transactions — auditors still need to see them.
- Sales invoices and receipts. All issued invoices in sequence, plus any credit notes. If you use an accounting system, export the sales ledger; if you use Excel, send the workbook.
- Purchase invoices and expense receipts. Organised by month or by supplier. Keep original PDFs or clear photos; the auditor will test a sample.
- Payroll records. Employment contracts, monthly payroll summaries, MPF contribution records, and IR56B/IR56E forms filed with the Inland Revenue Department.
- Inventory listing at year-end (if you hold stock). A stocktake count done as close to year-end as possible, priced at the lower of cost or net realisable value.
- Fixed asset register. Any equipment, furniture, laptops, or motor vehicles bought since incorporation, with invoices.
- Leases, loan agreements, and shareholder agreements. Anything that creates a long-term liability or commitment.
- Minutes of board and shareholder meetings. At minimum, the resolution approving the financial statements.
If you are using an accounting system like Giga Accounting, a single export will cover points 3, 4, 6, and 7. If you are running the books in Excel, expect to spend a few evenings tidying up before the auditor can start.
The three things that usually go wrong in a first audit
Having reviewed first-year audits for countless HK SMEs, the same three issues come up again and again. Spotting them early is the difference between an audit that takes three weeks and one that takes three months.
- Opening balances with no support. Founders often inject capital personally, pay for early expenses out of a personal card, and sort it all out “later”. By the time the auditor arrives, “later” has become “never”, and every injection has to be traced and documented. Keep a written loan or capital-injection note from day one.
- Bank reconciliations that do not tie. The auditor will reconcile the bank ledger to the bank statement to the cent. Missing FPS payments, duplicated journal entries, and transfers between the founder’s personal and company accounts are the three most common reasons a reconciliation breaks. Use a cloud accounting tool that pulls bank transactions directly, or commit to a disciplined manual import every month.
- Missing source documents. “The supplier emailed it to me, I think” is not a document. Every transaction needs a paper or PDF trail. Auditors test a sample, and if too many samples come back empty, they widen the sample — which widens the fee.
How to keep your first-audit fee down
First audits are almost always the most expensive one, because the auditor does all the opening-balance work at the same time as the current-year work. A few habits can take a meaningful chunk off the quote.
- Close the books monthly, not annually. A company that reconciles its bank balance every month hands the auditor a tidy trial balance. A company that has done nothing in 13 months hands over chaos. The fee gap is obvious.
- Keep the company bank account clean. No personal transactions. If the director has paid for something out of pocket, record it as a director loan and settle it monthly, not with a single year-end adjustment.
- Produce a proper chart of accounts early. A chart with 20 sensible account codes is worth much more than a chart with 200 random codes. Your auditor and your future self will both thank you.
- Organise documents digitally from day one. One folder per month, one sub-folder for sales and one for purchases. It sounds basic; it saves hours.
- Start the conversation with your auditor early. Many first-year companies leave it until the BIR51 arrives. By then you have less than three months to pull everything together. Engage an auditor when you are 10 months in, not 16.
Common questions founders ask
Do I need an audit if the company made no revenue? Yes. Dormant-status exemptions exist but have to be applied for separately under the Companies Ordinance, and they do not remove the Inland Revenue Department’s expectation of audited accounts when they issue a BIR51.
Can I use the same accountant who does my bookkeeping? The bookkeeper and the auditor must be independent people or firms. A single firm can do both through separate teams, but independence rules apply. This is one reason many SMEs keep their bookkeeping with one provider and their audit with another.
What if my records are a mess? Before engaging the auditor, engage a bookkeeper to clean up. A clean-up job at HKD 5,000–15,000 almost always saves more than that in audit fees and saves weeks of back-and-forth.
