Have you received a property tax assessment from Hong Kong’s Inland Revenue Department that seems incorrect or unfair? You’re not alone. Each year, thousands of property owners in Hong Kong find themselves disputing tax assessments, often facing strict deadlines and complex procedures. Understanding your rights and the proper dispute resolution process can mean the difference between a successful challenge and being stuck with an incorrect tax bill. This comprehensive guide walks you through the most common property tax disputes in Hong Kong and provides a clear roadmap for resolving them effectively.

Understanding Hong Kong Property Tax Fundamentals

Property tax in Hong Kong is a levy imposed on owners of land and buildings who derive rental income from properties located within the territory. Governed by the Inland Revenue Ordinance (Cap. 112), property tax is charged at a flat rate of 15% on the net assessable value of the property.

The net assessable value is calculated by taking the gross rental income, deducting rates paid by the owner and any irrecoverable rent, and then applying a standard 20% statutory allowance for repairs and outgoings. This 20% deduction is automatic and applies regardless of actual expenses incurred, which means landlords cannot claim deductions for actual repair costs, management fees, insurance, mortgage interest, or other property-related expenses under property tax.

Common Property Tax Dispute Issues

1. Rateable Value Assessment Disputes

Rateable value is an estimate of the annual rental value of a property in the open market, assuming the property is vacant and available to let. The Rating and Valuation Department conducts annual revaluations with valuation reference dates set each October, taking effect the following April. For 2025-26, the valuation reference date was October 1, 2024, with new rateable values effective from April 1, 2025.

Property owners may dispute rateable values if they believe their property has been valued above its proper rental value. To object, owners must submit a Proposal (Form R20A) to the Commissioner of Rating and Valuation on or before May 31 following the declaration of the new Valuation List in March.

2. Deduction and Allowance Disputes

A common source of disputes involves property owners attempting to claim deductions beyond the standard 20% statutory allowance. The Inland Revenue Department strictly limits deductions to:

• Rates paid by the owner (not those recovered from tenants)
• Irrecoverable rent confirmed as uncollectible during the year of assessment
• 20% statutory allowance for repairs and outgoings

The following expenses are not deductible for property tax purposes:

• Government rent
• Building management fees
• Insurance premiums
• Mortgage interest (unless claiming under Personal Assessment)
• Actual repair and maintenance costs exceeding the 20% allowance
• Decoration and renovation expenses
• Rent collection fees

3. Offshore Non-Taxable Status Claims

While Hong Kong operates a territorial tax system, property tax applies to all rental income derived from properties located in Hong Kong, regardless of where the owner resides or where rent is collected. Disputes arise when property owners incorrectly assume that offshore arrangements or foreign ownership can exempt them from property tax on Hong Kong properties.

4. Late Objection Disputes

There is an increasing number of disputes regarding late objections against tax assessments. The one-month objection deadline is strictly enforced, and late objections are rarely accepted unless exceptional circumstances exist, such as:

• Absence from Hong Kong during the objection period
• Serious illness preventing timely filing
• Other legitimate grounds beyond the taxpayer’s control

When a late objection is not accepted, the tax demanded becomes final and payable, and late payment surcharges are imposed.

5. Estimated Assessment Disputes

If a property owner fails to file a property tax return, the IRD may issue an estimated assessment based on its own calculations. If no valid objection is lodged within one month, this assessment becomes final and legally binding, even if the estimated income is higher than actual rental income received.

How to Resolve Property Tax Disputes: A Step-by-Step Guide

Step 1: Filing a Notice of Objection

If you disagree with a property tax assessment, you must file a written notice of objection with the Inland Revenue Department within one month from the date of issue of the assessment. The notice must clearly state the grounds for objection.

How to file:

• Complete Form IR831 (Notice of Objection/Application for Revision of Assessment)
• Submit via eTax account (for solely owned properties), by post to P.O. Box 28777, Concorde Road Post Office, Hong Kong, or by fax to 2877 1232
• If objecting to an estimated assessment, include a properly completed tax return with supporting documents

Step 2: IRD Review and Negotiation

In most cases, objections are handled through negotiations between the taxpayer and an IRD assessor. The assessor will review additional information and may issue a revised assessment or propose a basis for revision. This informal resolution stage allows many disputes to be settled without formal proceedings.

Step 3: Commissioner’s Determination

If no agreement is reached, the objection is referred to the Commissioner of Inland Revenue for determination. The Commissioner will review the objection and, within a reasonable time, may confirm, reduce, increase, or annul the assessment.

Step 4: Appeal to the Board of Review

If you disagree with the Commissioner’s determination, you may appeal to the Board of Review, an independent statutory body established to determine tax appeals. The appeal must be filed in writing within one month of receiving the Commissioner’s written determination.

Board of Review process:

• Submit written appeal to the Clerk to the Board of Review, including a copy of the Commissioner’s determination and grounds of appeal
• The Board is composed of members with legal and tax expertise, independent of the IRD
• All hearings are conducted in camera (private)
• The burden of proof rests on the appellant to demonstrate the assessment is excessive or incorrect
• Parties may submit documentary evidence and call witnesses, including expert witnesses
• The Board may confirm, reduce, increase, or annul the assessment, or remit the case to the Commissioner for reassessment
• If the Board does not reduce or annul the assessment, it may order the appellant to pay costs up to HKD 25,000

Step 5: Court Appeals

If either party remains dissatisfied with the Board’s decision, they may apply to the Court of First Instance of the High Court for leave to appeal on a question of law. The application must be filed within one month of the Board’s decision. With leave from the Court of Appeal, parties may appeal directly to the Court of Appeal, which is the highest authority for tax assessment cases in Hong Kong.

Property Tax Dispute Resolution Timeline

Critical Considerations During Dispute Resolution

Pay First, Argue Later

Hong Kong operates a “pay first, argue later” system for tax disputes. Regardless of filing an objection or appeal, any taxes due must be paid by the due date shown on the notice of assessment. Failure to pay will result in late payment penalties.

However, taxpayers may apply for a holdover (postponement) of tax payment if:

• Security for payment is provided
• The Commissioner grants permission for the holdover
• For provisional property tax, the assessable value for the current year is or is likely to be less than 90% of the preceding year, or you have objected to the preceding year’s assessment

Time Limits Are Strictly Enforced

Missing the one-month deadline for objections or appeals can be fatal to your case. The Commissioner or Board may extend deadlines only if satisfied there was reasonable cause, such as serious illness or absence from Hong Kong. Always calendar critical deadlines and seek professional assistance immediately upon receiving an assessment you wish to dispute.

Burden of Proof

In appeals to the Board of Review and courts, the burden of proof rests on the taxpayer to demonstrate that the assessment is excessive or incorrect. This requires gathering comprehensive evidence, documentation, and potentially expert testimony to support your position.

Professional Representation

Given the complexity of tax law and the formal procedures involved, particularly at the Board of Review and court levels, professional representation by tax advisors, accountants, or tax lawyers is highly recommended for significant disputes.

Holding Over Provisional Property Tax

Property owners may apply to hold over provisional property tax payments if certain conditions are met. The application must be made in writing no later than 28 days before the payment due date, or 14 days after the date of the notice of payment.

Grounds for holdover application:

• The assessable value for the current year of assessment is, or is likely to be, less than 90% of the assessable value for the preceding year
• You have objected to your property tax assessment for the preceding year

Alternative Dispute Resolution: Mutual Agreement Procedure

If you are a resident of Hong Kong or a jurisdiction with which Hong Kong has a Double Taxation Agreement (DTA), and face taxation not in accordance with DTA provisions, you can present your case to the competent authority under the Mutual Agreement Procedure (MAP). This is in addition to standard objection and appeal rights.

The MAP must generally be invoked within three years from the date of first notification of the action resulting in double taxation. Hong Kong has implemented BEPS measures through the Multilateral Instrument (MLI) to improve dispute resolution mechanisms under its DTAs.

Property tax disputes in Hong Kong require careful navigation of strict deadlines, formal procedures, and complex tax laws. While the system may seem daunting, understanding your rights and following proper procedures can lead to successful resolution of incorrect assessments. Remember that early professional advice, thorough documentation, and timely action are your best defenses against unfair tax assessments. If you’re facing a property tax dispute, don’t delay – consult with a qualified tax professional immediately to protect your rights and financial interests.
