The short answer
A Hong Kong business must file the profits tax return issued by the Inland Revenue Department (IRD) by the due date shown on it, normally one month after issue. Block Extension Schemes usually give agents and taxpayers longer. Companies file audited accounts with the return.
Once a business is registered and has started trading, the IRD issues a profits tax return, usually after a year of assessment ends. Corporations receive their returns in early April, and the return states a due date, normally within one month from the date of issue.
The IRD announces a Block Extension Scheme that gives longer deadlines when a tax representative submits the return. The dates depend on the financial year-end and whether the return is submitted electronically. Check the circular for the year concerned, because the dates differ by category.
What goes with the return:
- Companies: audited financial statements and a tax computation.
- Sole proprietors and partnerships: accounts or a profit computation, with supporting records available if asked.
After assessment, the IRD normally demands provisional profits tax for the following year, payable in two instalments, with a final settlement later. A business that has not received a return but is carrying on business should tell the IRD.
