2025 Hong Kong Company Tax Guide, a clear understanding of the key points of profits tax returns
Hong Kong adopts a two-tier profits tax system. Enterprises should file annual tax returns and save tax legally by deducting business expenses, depreciation allowances and other strategies to avoid late penalties.
Hong Kong's tax system
Hong Kong applies the territorial source principle to the taxation of profits derived from the carrying on of any trade, profession or business in Hong Kong, which is known as profits tax. Only profits arising in or derived from Hong Kong are chargeable to profits tax.
In short, a person who carries on business in Hong Kong but derives his profits from a place outside Hong Kong is not liable to tax in Hong Kong on those profits. Click on Profits Tax toInland Revenue Department of Hong KongWebsite to learn more.
Who needs to pay profits tax
Under the Inland Revenue Ordinance, Hong Kong profits tax is payable by persons who fulfil the following conditions:
The carrying on in Hong Kong of any trade, profession or business; the deriving of profits from such trade, profession or business; and the production of such profits in or from Hong Kong.
It can be understood that any person, including a corporation, partnership, trustee or body of persons, whose profits arising from or derived from business carried on in Hong Kong are chargeable to Hong Kong profits tax, irrespective of whether or not they are resident in Hong Kong.

Hong Kong Profits Tax Rate
Two-tier system Taxation
In Hong Kong, a two-tier tax system is used for calculating profits tax. There are two types of profits tax calculation methods, namely, limited companies and unlimited companies. In addition, if there are several subsidiaries under a group, a group can only file a two-tier tax return for a maximum of one of its subsidiaries, and the remaining subsidiaries have to be subject to the tax rate of 15% or 16.5%.
Calculation of Profits Tax for Limited Companies
The profits tax rate is 8.251 TP3T for the first HK$2 million of profits and 16.51 TP3T for profits in excess of HK$2 million.
Example 1
Based on the reported profit for the year $1,000,000, for example, has a rate of 8.25% because it is less than HK$2 million.
$1,000,000X8.25% = $82,500
Example 2
Based on the reported profit for the year $3,000,000 For example, since the profit is more than HK$2 million, the calculation is based on 8.25% tax rate for the first HK$2 million and 16.5% tax rate for the remaining HK$1 million.
($2,000,000X8.25%)+($1,000,000×16.5%)=$165,000+$165,000=$330,000
Calculation of Profits Tax for Unlimited Companies
The profits tax rate is 7.51 TP3T for the first HK$2 million of profits and 151 TP3T for profits in excess of HK$2 million.
Example 3
Based on the reported profit for the year $1,000,000, for example, has a rate of 7.5% because it is less than HK$2 million.
$1,000,000X7.5% = $75,000
Deductible items
The 100% of Profits Tax for 2023/24 will be reduced, subject to a ceiling of $3,000 per case, so that taxpayers can enjoy tax relief. In addition to the annual one-off profits tax reduction, more professionals will plan for legitimate tax savings through tax deductible items.
2024/25 Budget Profits Tax Concessions
In the latest Budget, it is proposed to reduce profits tax for the year of assessment 2024/25 for 100%, subject to a ceiling of HK$1,500, and the profits tax concession is also applicable to Hong Kong companies, not just individuals.
However, it is important to note that the 100% reduction in profits tax for 2023/24 is subject to a cap of $3,000 per case, and the cap for this year's Budget reduction is further reduced by half.
As tax is calculated on the basis of profitability, company expenses and expenses incurred for profitability are deductible for tax purposes, and equipment and fittings are also deductible for depreciation allowances.
Company's Daily Expenditure Items
Company office, warehouse or shop rental;
Electricity, water, internet and telephone bills for company offices, warehouses or shops;
Staff salaries, allowances, bonuses;
Mandatory and voluntary contributions to MPF;
Severance or long service payments made on termination of an employee's employment;
Insurance premiums related to business, e.g. labour insurance, company group medical insurance;
The cost of importing goods;
Entertainment and socialising expenses;
Bad and doubtful debts;
2024/25 Budget Tax Optimisation
Two new types of profits tax deductions will be introduced from the year of assessment 2024/25 onwards, including the reversion of rented properties and the abolition of the time limit for claiming industrial and commercial buildings and structures allowances.
The Financial Secretary has proposed to provide tax deduction for expenses incurred in restoring the leased property to its pre-leasing condition, the details of which will be known only after the completion of the legislative process.
The time limit for claiming tax allowances for industrial and commercial buildings and structures will be abolished. Depending on factors such as the construction cost of the property and the previous owner's balancing charge at the time of the change of ownership, the new owner can still claim tax allowances for the property.
Other special tax deductible expenses
Expenditure on building renovation
Capital expenditure incurred on refurbishment of commercial premises is deductible in equal instalments over a period of five years starting from the basis of assessment in which the amount is actually paid.
Expenditure on computer hardware and software
A lump sum deduction is allowed for the basis period in which the expenditure is incurred.
Expenditure on procurement of green facilities, e.g. electric vehicles, food waste machines, etc.
A lump sum deduction for the purchase of environmentally friendly machinery and installations is allowed in the basis period in which the expenditure is incurred.
Allowances for commercial and industrial buildings and structures
Industrial Building Initial Allowance: 20% of construction cost; Annual Allowance: 4% of construction cost
The annual allowance for commercial buildings is 4% of the construction cost.
If the relevant interest in the building or structure has been sold, the seller will be granted a balancing allowance or the seller will be subject to a balancing charge (collectively referred to as "balancing adjustment") as follows:
- If the proceeds of sale exceed the residual amount of expenditure incurred immediately prior to the sale, the excess is taxable as a balancing charge (subject to the aggregate of the initial and annual allowances previously granted to the vendor).
- If the remaining balance of expenditure immediately before the sale exceeds the proceeds of sale, the difference between the two is a balancing allowance and is deductible.
Machinery and Industrial Installations
Initial Allowance : 60% of the cost of the asset
Annual Allowance : Calculated on the basis of the diminishing value of the asset. The depreciation rates are prescribed by the Board of Inland Revenue and are 10%, 20% and 30%. Assets with the same depreciation rates for annual allowances are included in the same "aggregation group".
A 'balancing allowance' is granted if the taxpayer closes the business and there is no successor to the business. A 'balancing charge' is levied if, in any year, the proceeds from the disposal of one or more assets exceed the aggregate diminishing value of the 'aggregated group' to which those assets belong.
Donation deduction
Deduction is allowed for donations made to a charitable institution or trust of a recognised public character or to the Government for charitable purposes. However, the aggregate of the donations is required to be not less than $100 and not more than 35% of the adjusted assessable profits before deduction of the donations.
Frequently Asked Questions

Yes, a self-employed person who carries on a business in Hong Kong and makes profits is also liable to profits tax on his assessable profits.

Conclusion
The calculation of Hong Kong profits tax is not difficult, but the calculation of tax saving methods requires a more careful and professional approach, so as to save unnecessary tax payments, which should not be automatically deducted just because the proprietor thinks that the item can save tax, or even violate the law if the tax is incorrectly filed.
