When is profits tax due in Hong Kong?
The BIR52 Profits Tax Return filing deadline depends on accounting year-end: April and December year-ends by 15 August, November year-ends by 15 May, other year-ends within 1 month of issue. Tax is paid in two instalments: 75% provisional tax with the current year assessment, balance when the assessment finalises.
Detailed Explanation
## When Is Hong Kong Profits Tax Due?
Hong Kong Profits Tax is paid in two stages, following the IRD's assessment and billing cycle:
1. Provisional Tax
raised alongside the current year's assessment, estimated at 100% of the prior year's assessable profits. Typically 75% of provisional tax is demanded simultaneously with the current year's tax bill. 2. **Balance of Tax**: any underpayment or overpayment from the provisional tax is settled when the following year's assessment finalises.
## BIR52 Filing Deadlines by Year-End
The IRD issues BIR52 Profits Tax Returns in bulk each April. Deadlines (under block extension for tax-representative clients) are:
| Accounting Year-End | Filing Deadline | |---|---| | April year-end | 15 August | | November year-end | 15 May (following year) | | December year-end | 15 August | | January to March year-ends | 31 October or 31 January (depending on block) | | May to October year-ends | 1 month from date of issue |
These deadlines apply when the company is represented by a registered tax firm enrolled in the IRD's block extension scheme. Unrepresented companies have only 1 month from the date the BIR52 is issued.
## How the Payment Cycle Works
Year 1 (first profitable year):
A company earns assessable profits of HKD 3M in Year 1 (year ended 31 December 2024). Tax = HKD 660,000.
The IRD issues an assessment in, say, October 2025: - Current year tax: HKD 660,000 - Provisional tax for Year 2 (estimated at Year 1 assessable profits): 75% of HKD 660,000 = HKD 495,000 - Total demanded: HKD 1,155,000
Year 2:
Actual Year 2 profits = HKD 4M. Tax = HKD 825,000. - Credit for provisional tax already paid: HKD 660,000 - Balance: HKD 165,000 + new provisional for Year 3 at 75% of HKD 825,000 = HKD 618,750
## What Is Filed with the BIR52
The BIR52 must be accompanied by: - Audited financial statements (mandatory for all HK private companies) - Tax computation reconciling accounting profit to assessable profit - Capital allowance schedules - Offshore profits claim letter (if applicable)
## Penalties for Late Filing
Late filing of the BIR52 results in: - IRD raising an estimated assessment at a high level - Penalty of up to 3x the tax assessed - Interest at 8.25% per year on unpaid tax
## Holdover of Provisional Tax
If the company expects current year assessable profits to be significantly lower than the prior year (by more than 10%), it can apply to hold over (defer) the provisional tax. The application must be made before the provisional tax payment date. If profits turn out to be higher than the holdover estimate, additional tax and a surcharge apply.
## Salaries Tax Payment Dates
For comparison, Salaries Tax for individuals is demanded in two instalments: - First instalment: January following the year of assessment - Second instalment: April following the year of assessment

Real-World Examples
April year-end company
A company with a 30 April 2025 year-end receives its BIR52 in April 2026. It is represented by a tax firm in the block extension scheme. Filing deadline: 15 August 2026. Audited accounts must be complete by mid-July 2026 to allow the tax computation to be prepared and filed by 15 August.
Company applying for provisional tax holdover
A construction company had HKD 5M profits in 2024 but expects 2025 profits of only HKD 1.5M due to a project delay. It receives a provisional tax demand of HKD 825,000 (75% of Year 2024 tax). It applies for holdover based on estimated 2025 profits of HKD 1.5M. Holdover approved: provisional tax reduced to 75% of HKD 1.5M x 8.25% = HKD 92,812. Cash preserved.
First year profitable company
A company earns HKD 2M in its first year. Tax = HKD 165,000 (all at 8.25%). Assessment issues. The company also receives a provisional tax demand for Year 2 at 75% of HKD 165,000 = HKD 123,750. Total cash outflow in the first year of profit: HKD 288,750. Many founders are surprised by the double demand.
Common Mistakes to Avoid
- Not budgeting for provisional tax in the first profitable year (the simultaneous demand for current year tax plus 75% of next year's provisional tax is a significant cash event)
- Missing the block extension deadline because the company is not represented by an enrolled tax firm
- Not applying for provisional tax holdover when profits are expected to be significantly lower than the prior year
- Filing the BIR52 without audited accounts attached (the IRD requires audited statements for all HK companies)
Frequently Asked Questions
What is provisional tax in Hong Kong?
Provisional tax is the IRD's advance assessment for the current year, based on the prior year's assessable profits. It is raised alongside the prior year's assessment. 75% is typically payable concurrently with the prior year balance. If actual profits differ, the difference is settled in the following year's assessment.
Can I object to a Profits Tax assessment?
Yes. An objection must be filed within 1 month of the date of the assessment notice. The IRD will review the objection and may revise the assessment. If unresolved, the case can be referred to the Board of Review or the courts.
How do I pay Profits Tax in Hong Kong?
Profits Tax is paid via electronic transfer, cheque, or PPS system referencing the IRD tax reference number. Online payment via eTAX is available. The payment reference is on the demand note.
What happens if I cannot pay Profits Tax on time?
Contact the IRD before the payment due date to request an instalment arrangement. The IRD can agree to monthly payments, though interest applies. Ignoring the demand results in enforcement action including attachment of bank accounts.
Can I offset my HK losses against future profits?
Yes. Tax losses from a HK trade carry forward indefinitely against future assessable profits from the same trade. They cannot be carried back or transferred to a different business.
Practical Tips
- Create a cash flow reserve from day one of trading: set aside 25-30% of monthly profits in a dedicated tax reserve account. When the first Profits Tax demand arrives (with provisional tax), you will not be caught short.
- Engage a tax representative enrolled in the IRD block extension scheme to get the extended filing deadlines, which are substantially more generous than the default 1-month window.
- Calendar your filing deadline based on your year-end as soon as you incorporate. Miss it and you get an estimated assessment set punitively high.
- If profits are going to be significantly lower this year than last year, apply for provisional tax holdover early — do not wait for the demand to arrive.
