Hong Kong Rental Tax: Property Tax vs Personal Assessment
🎧 Listen to this article

In Hong Kong, when declaring rental income, landlords mainly have two options: "Property Tax" and "Personal Assessment." What are the differences between the two? Which method allows you to deduct "mortgage interest"? There are significant differences in the calculation methods and deductible items between the two. This article will introduce the basic operations and applicable situations of the two systems.
1. What is "Property Tax"?
"Property Tax" is a tax levied by the Inland Revenue Department on rental income from Hong Kong properties. Its calculation method is relatively simple and straightforward, applying a uniform standard rate.
- Standard Rate: 15%
- Calculation Formula: [Rental Income - Rates Paid by Landlord - Irrecoverable Rent (if any)] x 80% x 15%
- Statutory Allowance for Repairs and Outgoings: The Inland Revenue Department uniformly deducts 20% of rental income as an allowance for repairs and outgoings.
Note that under the Property Tax system:
- Actual renovation expenses cannot be deducted
- Management fees and agent commissions cannot be deducted
- Mortgage interest cannot be deducted
2. What is "Personal Assessment"?
"Personal Assessment" is not an independent tax but a consolidated assessment mechanism that allows taxpayers to combine income from different sources, including:
- Salaries income
- Profits income (if applicable)
- Rental income
After consolidation, tax is calculated as follows:
- Progressive tax rates (2% to 17%)
- Or standard rate (15%) 👉 Whichever is lower
When eligible, choosing Personal Assessment allows:
✔ Deduction of mortgage interest on the rental property (capped at the net assessable value of the property)
In addition, taxpayers can still claim various personal allowances, such as:
- Basic allowance
- Married person's allowance
- Child allowance
- Dependent parent allowance
These allowances can effectively reduce overall taxable income.
Comparison of the Two Tax Options: Which One Suits You?
The actual choice depends on your personal financial situation. Below is an analysis of common scenarios:
Scenarios more suitable for considering "Personal Assessment"
- Property with mortgage loan
If interest expenses are high, interest deduction can help reduce tax burden - Overall income is low or no salary income
Personal allowances can offset part or all of the rental income - Eligible for multiple allowances
Helps further reduce taxable amount
Scenarios where "Property Tax" can be maintained
- Property without mortgage (fully paid)
No interest expenses to deduct - Salary income is already near or at the standard rate level
Consolidating income may not effectively lower the tax rate
It is worth noting that the tax authority usually compares different calculation methods during assessment and applies the result most favorable to the taxpayer.
3 Essential Points to Note for Rental Tax Filing
- Keep rates receipts: Only rates paid by the landlord are deductible. If the tenant pays the rates, the landlord cannot claim a deduction. Be sure to keep rates receipts as proof.
- Tax deduction for bad debts: If you unfortunately encounter a defaulting tenant, the rent owed (irrecoverable rent) can be declared as a deduction on the tax return. If the rent is later recovered, it must be reported as income in the year of recovery.
- Apply early on the form: To choose Personal Assessment, you must tick the "Apply for Personal Assessment" box in Part 7 of the tax return (BIR60); otherwise, the tax authority will only issue a tax bill based on standard property tax.
