⚠ Late Filing Attracts Automatic Penalties
IRD issues automatic penalties for late profits tax returns — starting at HKD 1,200 and escalating to court summons. A tax representative can extend deadlines through the Block Extension Scheme.
Common Challenges
Audit Requirement
All HK companies must have accounts audited by a Certified Public Accountant (practising) before submitting the profits tax return.
⚠ Risk: Unaudited accounts → IRD rejection + penalties
Filing Deadlines
Profits tax returns are due within 1 month of issue (or up to April under Block Extension). Missing deadlines = automatic penalties.
⚠ Risk: Late filing → HKD 1,200–10,000 penalty + interest
Missed Deductions
Many companies miss legitimate deductions under IRO s.16 — bad debts, depreciation, R&D, charitable donations (s.16C), and more.
⚠ Risk: Missed deductions → overpaying tax for years
Tax Computation Errors
Profits tax computation requires adjusting accounting profit for disallowable items — capital expenditure, private use, entertainment limits.
⚠ Risk: Errors → IRD queries, back-assessments, interest

Frequently Asked Questions
When is my profits tax return due?
IRD issues profits tax returns to companies on the first working day of April each year. For businesses with a 31 March year-end, the return is typically due within 1 month. Tax representatives on the Block Extension Scheme get extended deadlines — up to November for December year-ends.
What is the Block Extension Scheme?
The Block Extension Scheme allows tax representatives (CPAs) to obtain automatic extended deadlines for filing profits tax returns on behalf of their clients. This is why having a CPA as your tax representative can give you up to 6 extra months.
What expenses are deductible under IRO section 16?
Section 16 allows deductions for expenses incurred in the production of chargeable profits: staff costs, rent, utilities, professional fees, bad debts (s.16(1)(d)), R&D (s.16B), donations to approved charities (up to 35% of profits under s.16C), and capital allowances on plant/machinery.
What items are NOT deductible?
Capital expenditure, domestic/private expenses, losses not connected with the trade, income taxes paid in HK or overseas (unless credit claimed), and entertainment expenses (partially restricted) are the main disallowable items per IRO s.17.
Do I need an audit if my company had no income?
Yes. All HK incorporated companies must have their accounts audited regardless of activity level. Dormant companies should file a nil profits tax return with a dormancy certificate.
What is the penalty for late filing?
IRD can impose a penalty of HKD 1,200 for first-time late filing, escalating with repeat offences. Serious or deliberate non-compliance can result in court summons and fines up to HKD 10,000 plus treble the tax undercharged.
