Are you maximizing your commercial property returns while staying compliant with Hong Kong tax regulations? With over 1.2 million properties generating rental income in Hong Kong, understanding the property tax system is crucial for commercial property owners. Whether you own office space, retail shops, or industrial units, this comprehensive guide will walk you through filing your property tax return accurately and efficiently step by step.
Understanding the Hong Kong Commercial Property Tax System
Hong Kong adopts the territorial source principle of taxation, meaning that only income arising in or derived from Hong Kong is subject to tax. For commercial property owners, this means rental income derived from your properties in Hong Kong is subject to Property Tax, while income from overseas properties is not taxed in Hong Kong. The system is designed to be relatively straightforward, but requires careful attention to detail.
How Property Tax is Calculated
The calculation of Property Tax follows a specific formula to arrive at your Net Assessable Value (NAV), which is then taxed at a standard rate of 15%. Below is the exact calculation method for the 2024-25 year of assessment:
Computation Item
Calculation Basis
Example (HKD)
Gross Rental Income
Total rent received for the entire year
1,200,000
Less: Rates Paid
Government rates paid directly by the owner
(50,000)
Net Rental Income
Gross Rental Income - Rates
1,150,000
Less: 20% Statutory Allowance
Net Rental Income × 20%
(230,000)
Net Assessable Value (NAV)
Net Rental Income × 80%
920,000
Property Tax Payable
Net Assessable Value × 15%
138,000
⚠️ Important Note: The 20% statutory allowance is granted automatically without requiring you to provide receipts for individual repair expenses. However, if your actual repair expenses exceed 20% of the net rental income, you cannot claim the excess amount under the Property Tax rules.
Filing a commercial property tax return is straightforward as long as you follow a systematic approach. Below is a complete guide to completing and submitting Form BIR57:
Gather Required Documents: Organize all tenancy agreements, rent receipts, bank statements showing rent deposits, and records of rates paid. Categorize them by property and year of assessment.
Calculate Gross Rental Income: Sum up all rental payments received during the year of assessment (April 1 to March 31). Include any service fees, management fees, or other payments paid by the tenant.
Deduct Rates Paid: Deduct the government rates directly paid by you for the property during the year.
Apply the 20% Allowance: Calculate 20% of the amount after deducting rates as the statutory allowance for repairs and outgoings.
Complete Form BIR57: Fill in all figures accurately into the designated sections of the form, ensuring the calculations match your supporting records.
Submit Before the Deadline: File electronically via "eTAX" or submit the paper form before the April 30 deadline.
💡 Pro Tip: Using the Inland Revenue Department's "eTAX" platform for electronic filing allows for faster processing and immediate receipt confirmation. E-filing also reduces the risk of lost documents and makes it easy to access past filing records.
Proper documentation is your best defense against tax audits and penalties. Under the Hong Kong Inland Revenue Ordinance, you must retain the following records for at least 7 years:
Filing tax returns on time is not only a good habit, but also critical to avoiding heavy financial penalties. The Inland Revenue Department enforces compliance very strictly, and the costs of late filing can accumulate rapidly.
Key Tax Filing Deadlines
Annual Tax Filing Deadline: April 30 each year (for the preceding year of assessment from April 1 to March 31)
Tax Payment Deadline: Usually after the issuance of the Notice of Assessment (around January to February)
Application for Extension: Must be submitted in writing before the deadline, supported by reasonable grounds
Penalties for Non-Compliance
Violation
Penalty
Other Consequences
Late submission of tax return
Up to 5% of tax payable
Continued delays may incur additional penalties
Late payment of tax
Interest charged at an annual rate of 8.25% on outstanding tax
Compounded daily from the tax due date
Under-reporting of income
Up to 300% of tax undercharged
Fraudulent acts may lead to prosecution
Wilful tax evasion

Imprisonment for up to 3 years
⚠️ Important Note: Effective from July 2025, the annual interest rate on tax in default is 8.25%. This rate is reviewed periodically by the Inland Revenue Department, so please be sure to check the latest rate when calculating potential penalties.
Even experienced property owners may make mistakes that lead to tax audits or penalties. Here are the most common pitfalls and how to avoid them:
1. Incorrect Reporting of Rental Income
Many property owners fail to declare all rental-related income. Please remember to report:
Base rent along with any surcharges
Service charges paid by tenants
Management fees collected
Parking income derived from the property
Any other payments received from tenants
2. Misunderstanding the 20% Statutory Allowance
The 20% statutory allowance covers repairs and outgoings, but many property owners mistakenly attempt to claim additional repair expenses. Please remember: under Property Tax rules, you cannot claim actual repair costs in excess of the 20% statutory allowance.
3. Forgetting Vacancy Period Adjustments
If your property was vacant during the year of assessment, you may claim a proportionate reduction in the assessable value. Accurately record the vacancy dates and calculate the adjustment.
In certain circumstances, rental income from commercial properties may be assessed under Profits Tax rather than Property Tax. This generally applies when:
You operate a property leasing business holding multiple properties
You provide substantial additional services to tenants
Your leasing activities constitute a trade or business
Under Profits Tax, you can claim actual expenses (rather than just the 20% statutory allowance) and may enjoy depreciation allowances on qualifying assets. The two-tiered profits tax rates for the 2024-25 year of assessment are:
Corporations: 8.25% on the first HK$2 million of profits, and 16.5% on the remainder
Unincorporated businesses: 7.5% on the first HK$2 million of profits, and 15% on the remainder
⚠️ Important Note: Only one entity within a group of connected entities can elect for the lower tax rate on the first HK$2 million of profits. Please consult a tax professional to determine whether Property Tax or Profits Tax is more advantageous for your specific situation.
