Hong Kong taxes profits territorially: profits sourced outside Hong Kong can, on a successful claim, escape Hong Kong profits tax entirely. That single fact sells a lot of company formations. What the brochures skip is the second half of the sentence: offshore treatment is claimed and defended, not granted automatically — and the Inland Revenue Department checks. Here is what that process actually looks like, from the claims we've filed and defended over the years.
Scope note: this article covers offshore claims on active trading and service profits. Certain foreign-sourced passive income (dividends, interest, IP income, disposal gains) received in Hong Kong by companies in multinational groups falls under the separate FSIE regime introduced in 2023 — a different set of rules from what follows.
The records you're expected to keep
A company intending to claim offshore status is expected to keep genuinely detailed records — not just the numbers, but the trail behind them:
- Complete transaction records, end to end
- Email correspondence around deals
- Sales invoices and purchase invoices
- Even travel records for the people running the company
If that list surprises you, that's the point: the claim is evidentiary. It's won or lost on paperwork you either kept — or didn't — long before filing. (It's also why books that merely "break even by magic" are disqualifying; see what cheap formation packages actually cost.)
The questionnaire: how the IRD tests a claim
Once a claim is filed, the IRD responds with a detailed questionnaire designed to establish whether the profits genuinely arose outside Hong Kong. In practice it asks for:
- Directors' details and travel schedule — establishing that the director is not, in fact, spending most of their time in Hong Kong
- One or two complete sample transactions, shown A to Z — how the deal came about, the correspondence, the supporting documents, and the final resolution
The test is two-sided, and this is what most people miss: it isn't enough that you operate from outside Hong Kong. The IRD also looks at the other end of the transaction — a customer sitting in Hong Kong undermines the claim, however offshore your own desk is.
The numbers, honestly
- Timeline: around 3–4 months end to end — filing, questionnaire, approval
- Cost: typically billed by the hour; an average claim runs in the region of HK$30,000
- Track record: every claim we have chosen to file has been approved — roughly fifteen of them to date
That 100% figure deserves its footnote, because the footnote is the real advice: clients with no realistic chance of offshore status are told not to apply. The success rate isn't magic; it's selection. A weak claim doesn't just fail — it invites scrutiny you didn't need. Part of what you pay an adviser for is being told no before the IRD says it for you.
When we advise against filing
Two situations account for most of the claims we decline to pursue:
- Customers based in Hong Kong. The transaction itself fails the territorial test, whatever your own travel schedule says.
- Records too thin to substantiate the claim. If the A-to-Z of a transaction can't be reconstructed on paper, there is nothing to defend the claim with.
And one reminder that belongs in every conversation about this topic: an approved offshore claim does not exempt you from accounting and audit. Every Hong Kong company prepares audited accounts annually, offshore or not (the only narrow exception: formally declared dormant companies) — the misconception we hear literally a hundred times.
Setting yourself up from day one
The best offshore claim is prepared years before it's filed — by the way the company runs. Keep the correspondence. File the invoices, both directions. Log the travel. Run books that can show any transaction A-to-Z on request — which is exactly the discipline Certanta, our bookkeeping arm, builds in from the first transaction. When the questionnaire arrives, we draft the response from the documents you provide; the stronger the records, the shorter that exercise gets.

Talk to usFrequently asked questions
Is offshore status automatic if my customers are outside Hong Kong?
No — it must be claimed and defended with evidence. The IRD tests where the profit-generating activity actually happened, via a questionnaire and full transaction documentation.
If my claim is approved, am I exempt from accounting and audit?
No. Audited accounts remain mandatory every year (the narrow exception being formally declared dormant companies). The claim affects where profits are taxed — not your accounting obligations.
How long does it take, and what does it cost?
In our practice, around 3–4 months end-to-end; typically billed hourly, with an average claim in the region of HK$30,000 depending on complexity.
When should a company NOT file?
When customers are based in Hong Kong, or when the records can't substantiate the claim. In those cases we advise clients not to apply.
