Hong Kong Company Tax Filing: 2026 Fees, Deadlines and 6 Selection Criteria

When you look for a Hong Kong company tax filing provider, price should not be the only thing you compare. What matters more is whether the provider can join up bookkeeping, statutory audit, profits tax filing and correspondence with the Inland Revenue Department. Under the Hong Kong Companies Ordinance, a company's financial statements must in principle be audited, unless the company has formally become dormant; the auditor's report must be signed by a qualified practising accountant. Quotes only become comparable once you have explained your company's situation, transaction volume and cross-border complexity. For the full picture of the process, start with the Hong Kong audit and tax filing process.

First, clear up a common misconception: what changed from April 2023 is the supporting-document requirement for profits tax returns — companies with gross income, including small companies whose gross income does not exceed HK$2 million, must now submit financial statements and tax computations together with the return. This is not “nil filing was finally abolished in 2023”; the audit obligation under company law already existed. See the IRD filing reminder and the Companies Registry note on accounts and audit.

The Short Answer: Matching Services to Three Types of Company

These are 2026 planning budgets — not a Chan & Chung quotation, and not government-set pricing. The NT$ figures use the Hong Kong dollar spot selling rate of HK$1 = NT$4.149 posted by Bank of Taiwan on 17 July 2026; your actual transaction rate will differ.

How to Read Hong Kong Tax Filing Fees in 2026

Published price lists start at around HK$1,799–3,000 for handling a dormant company and around HK$5,000–6,000 for a small business audit; company secretarial services commonly run about HK$1,300–8,000 per year. Treat these figures only as a benchmark for comparison — see, for example, published audit pricing, audit and tax filing packages and this company secretary fee comparison. You will get a more accurate picture by putting tax filing back into your full-year spending, so read it alongside the annual maintenance cost of a Hong Kong company and the company secretary duties guide.

Fees usually rise not because there are more forms, but because the working papers are harder to verify: multi-currency settlement through Stripe, PayPal, Amazon or Shopify; shareholder current accounts and payments-on-behalf without documentation; inventory, related-party transactions or an offshore profits claim; or a full year of bookkeeping left until year-end. Do not believe unconditional promises such as “tidy books always save you 30%”. Ask the firm to spell out in writing how it charges for transaction volume, catch-up bookkeeping, audit queries and additional hours.

The First Tax Return and the N / D / M Code Timetable

The Inland Revenue Department generally issues the first BIR51 about 18 months after incorporation; the first return can usually be filed within 3 months of the issue date, after which the deadline printed on the return governs. The block extension scheme for 2025/26 applies to taxpayers represented by a tax representative and is divided by financial year-end date:

The dates can shift each year, so do not write “some day in August or November” into a permanent calendar. Check the IRD's Tax Representatives' Corner against your return, and schedule the annual return, business registration and other deadlines together in a Hong Kong annual compliance calendar. Appointing a tax representative gives you access to the block extension scheme, but it does not mean every extension is granted automatically.

Six Criteria for Choosing an Accounting Firm

1. Check the practising qualification. The HKICPA membership list confirms CPA status, but the current practising certificate should be verified separately with the Accounting and Financial Reporting Council. Do not rely on the word “accountant” printed on a business card.
2. Confirm industry experience. Revenue recognition and documentation chains differ substantially between cross-border e-commerce, SaaS, trading and holding companies.
3. Ask who signs the auditor's report. An intermediary or consultant can coordinate the work, but a statutory audit must still be performed by a qualified Hong Kong practising accountant.
4. Ask for the scope in writing. Itemise bookkeeping, audit, BIR51, tax computation, IRD enquiries, offshore claims and fees for supplementary documents.
5. Compare the total, not the starting price. A single point of contact reduces communication overhead, but you still need to confirm audit independence and check for duplicated charges.
6. Test response speed. Taiwanese business owners should at minimum confirm Traditional Chinese communication, Hong Kong working hours and an urgent document-submission window.

Before signing, ask three more questions: “How many transactions does this quote assume? Who is the named tax representative? How is out-of-scope work priced?” If the answers are vague, move on to the next firm.

Five Common Pitfalls

• Treating “no operations” as formally dormant. Whether a company qualifies as a dormant company under the Companies Ordinance depends on set procedures and conditions; you cannot decide it yourself simply because there was no income.
• Receiving a return and doing nothing with it. Even if you believe no tax is payable, a return that has been issued must still be filed on time; late filing can lead to an estimated assessment, penalties or prosecution. The IRD penalty policy sets out that filing late without reasonable excuse carries a fine of up to HK$10,000, plus a possible further penalty of up to three times the tax undercharged, with actual treatment depending on the case.
• Assuming offshore source means no filing obligation. Hong Kong applies the territorial source principle, but the test is “what you did to earn that profit, and where you did it” — not simply the customer, the bank account or the contract address. See the IRD on the territorial source principle and the key points of a Hong Kong offshore profits tax claim.
• Comparing audit fees only. A low headline price may exclude catch-up bookkeeping, tax computation, IRD enquiries or company secretarial work.
• Changing the year-end date purely to get an extension. A March or December year-end often allows more preparation time, but it still has to fit the parent company, the operating cycle and the first accounting period.

FAQ

Can a company skip tax filing if it has no operations?

Not as a blanket rule. Once a profits tax return is issued, it must be dealt with by the deadline; whether an audit can be dispensed with depends on whether the company has lawfully become dormant, not simply on whether revenue was zero.

How much do tax filing and audit cost per year?

A small operating company can budget HK$15,000–28,000 (approx. NT$62,200–116,200) as a starting point; cross-border, multi-currency or unreconciled books can run HK$22,000–48,000 (approx. NT$91,300–199,200). The written quotation always governs.

When will the first tax return arrive?

The Inland Revenue Department generally issues the first BIR51 about 18 months after incorporation, usually allowing 3 months to file. If you receive a provisional return earlier or the return states a different deadline, follow the actual document.

Can I file the return myself?

A company may prepare and submit the forms itself, but where an audit is required by law you cannot sign your own auditor's report. You would also carry full responsibility for the tax computation, document formats and deadline management.

Are offshore profits always tax-free?

Not necessarily. The source of profits is a question of fact and turns on where the core profit-generating activities take place. Certain multinational entities may additionally be caught by the foreign-sourced income exemption regime and its economic substance requirements. Any claim of “guaranteed approval” is not credible.

How can I quickly rule out an unsuitable firm?

If you cannot verify the signer's current practising qualification, if the firm will not put the scope of services in writing, or if it will not explain how additional hours are priced — any one of these is enough that you should not sign on price alone.
