The short answer

A first late filing of a Hong Kong profits tax return is usually penalised at about 10% of the tax undercharged (the tax left unpaid), or 20% if the return is filed after two or more estimated assessments; repeat offences cost more. By law the Inland Revenue Department can prosecute under section 80 or charge additional tax of up to three times the tax undercharged under section 82A.

Legal penalties. Without a reasonable excuse, failing to file a return in time or to notify chargeability can lead to:

  • Prosecution under section 80(2): a fine of HK$10,000 plus a further fine of up to three times the tax undercharged.
  • Additional tax under section 82A instead of prosecution: up to three times the tax undercharged.

Policy scale for profits tax (no field audit). The Inland Revenue Department's (IRD's) penalty policy uses these starting points, adjusted for the facts:

OffenceReturn filed lateFiled after two or more estimated assessments
First10% of tax undercharged20%
Second within 5 years20%30%
Third or more within 5 years35%50%

Factors include length of delay, the amount of tax, the reasons and any remedial steps. The percentages are general guidance only.

Other consequences. The IRD can issue estimated assessments. A return also may be treated as invalid if not accompanied by the required documents.

To reduce risk

  • Use the Block Extension Scheme through a tax representative.
  • File on time even if the accounts are incomplete, or ask for an extension in writing at least 14 days before the due date.

A delay in an extension request is not a defence by itself.

Legal basis and sources

The law

  • Inland Revenue Ordinance (Cap. 112), s.80
