IRD section 82A additional tax in Hong Kong: what it is and how to respond

When an Inland Revenue Department (IRD) enquiry, field audit or investigation ends with an agreed understatement — or when an incorrect return or failure to notify chargeability is found — the Commissioner may assess additional tax under section 82A of the Inland Revenue Ordinance (IRO), Cap. 112. This is a monetary penalty, not a court fine by itself. This note summarises the public framework on the IRD Penalty Policy page and in DIPN 11 (Revised) — Field Audit and Investigation. For the overall process when a letter first arrives, see our companion note on how to handle an IRD investigation, field audit or enquiry. General information only, not tax or legal advice.

Confirm every deadline and figure against the notice you receive and the current IRD Penalty Policy / DIPN pages. Percentages below are the Department’s published guidance and can move up or down on the facts.

1. What section 82A is (high level)

Part XIV of the IRO gives the Commissioner several tools when obligations are not met: prosecution under sections 80 or 82, compounding (a monetary settlement instead of prosecution), or assessment of additional tax under section 82A. Section 82A is typically used where there is no prosecution under section 80(2) or 82(1) for the same offence.

In broad terms, section 82A can apply where a person, without reasonable excuse:

• makes an incorrect return or statement affecting tax liability;
• omits or understates income or profits;
• fails to furnish a return in time; or
• fails to inform the IRD of chargeability to tax.

The maximum additional tax for these classic offences is three times the tax undercharged (or that would have been undercharged if the omission had not been detected). Separate limbs of section 82A also cover certain transfer-pricing and information-reporting situations, with their own caps described on the Penalty Policy page.

2. Notice and your right to make representations

Before assessing additional tax, the Commissioner or a deputy must give written notice of the intended assessment and the alleged offence. You are invited to submit written representations (and evidence if required) and must be given not less than 21 days from service of the notice. Use that window carefully — calm, factual submissions about co-operation, disclosure timing, business sophistication and any reasonable excuse can matter.

After an additional-tax assessment is issued, you may normally appeal to the Board of Review within one month of the notice. Settlement of basic tax earlier (the settlement form described in DIPN 11) usually settles basic tax only; penalty remains a separate decision.

3. Penalty Policy overview (field audit / investigation)

Where a field audit or investigation has been conducted, Part D of the Penalty Policy uses a loading table based on:

• Nature of omission / understatement — Group (a) intentional disregard / deliberate cover-up; Group (b) recklessness / gross negligence; Group (c) failure to exercise reasonable care; and
• Quality of disclosure — full voluntary disclosure; disclosure with full information promptly on challenge; incomplete or belated disclosure; disclosure denied.

“Normal loading” and “maximum including commercial restitution (C.R.)” are expressed as percentages of the tax undercharged. The published table ranges from relatively low loadings for full voluntary disclosure of Group (c) cases, up to very high loadings where disclosure is denied in Group (a) cases. Commercial restitution compounds at rates described in the policy notes.

Aggravating and mitigating factors include the taxpayer’s education and business sophistication, attitude and co-operation, length of the offence period, and the scale of understatement. In the generality of cases the policy allows adjustment of up to about 25% either way; exceptional cases may move further. Second and subsequent offences within five years attract upward adjustments (about 10% / 25% per the policy).

For profits tax cases without field audit or investigation, Part E sets a different scale for late filing / failure to notify (often starting around 10%–20% for a first offence, rising for repeats within five years). Omission or understatement of profits still points back to the Part D framework, with the absence of an audit treated as a mitigating factor. Salaries and property tax non-audit cases have their own Part F scale.

4. Practical response steps

1. Diary the 21-day (or longer) representation deadline on the section 82A notice — and any Board appeal deadline later.
2. Reconcile the “tax undercharged” figure with the years and assessments already agreed or determined; ask your adviser to check arithmetic and year allocation.
3. Assemble a fact pack — timeline of disclosure, letters sent, interview co-operation, and any steps taken to correct systems going forward.
4. Address the loading group candidly — do not over-claim “voluntary disclosure” if the IRD already challenged you; focus on prompt, complete information after challenge if that is the accurate category.
5. Coordinate with any settlement form already signed — clarify what remains open on penalty.
6. Keep one consistent narrative with the field-audit / investigation file; contradictions hurt both basic tax and penalty discussions.
