Understanding When to Challenge Your Hong Kong Tax Assessment

Receiving a tax assessment from the Hong Kong Inland Revenue Department (IRD) that appears incorrect or excessive can be concerning for business owners. While not every disagreement warrants a formal challenge, understanding when and how to object to an assessment is crucial for protecting your company’s financial interests. This comprehensive guide outlines the key indicators that suggest you should challenge a Hong Kong tax assessment, the valid grounds for objection, and the strategic considerations involved in the decision-making process.

The One-Month Window: Critical Timeline for Objections

Time is of the essence when considering an objection to a Hong Kong tax assessment. According to the IRD, the notice of objection must be received within one month after the date of issue of the notice of assessment. This strict deadline is non-negotiable except in limited circumstances.

Late Objections: Limited Exceptions

The Commissioner of Inland Revenue may consider late objections only if satisfied that you were prevented from lodging within the specified time due to:

• Absence from Hong Kong
• Sickness
• Other reasonable causes

You must provide detailed reasons in your notice of objection or Form IR831 explaining why the deadline was missed. Given the difficulty of obtaining extensions, business owners should treat the one-month deadline as absolute and seek professional advice immediately upon receiving an assessment that appears questionable.

Valid Grounds for Challenging a Tax Assessment

Simply disagreeing with the amount assessed is insufficient. You must demonstrate why the assessment is incorrect according to tax law or fact. The following are recognized valid grounds for objection:

1. Factual Errors in the Assessment

The IRD may have made calculation errors or included income that was never received. Common factual errors include:

• Incorrect income figures that don’t match your financial records
• Double-counting of revenue from the same source
• Inclusion of transactions that never occurred
• Mathematical errors in computing assessable profits
• Estimated assessments issued without proper basis when returns were actually filed

Action required: Meticulously compare the figures on the assessment notice with your financial records, including reported income, allowances applied, and deductions claimed.

2. Incorrect Application of Tax Law

The assessor may have misinterpreted or misapplied provisions of the Inland Revenue Ordinance. Common legal interpretation issues include:

• Incorrect application of allowances or deductions
• Misclassification of revenue versus capital receipts
• Improper application of depreciation allowances
• Errors in determining the applicable tax rate
• Misunderstanding of specific industry-related tax provisions

3. Offshore Income Wrongly Assessed

Hong Kong’s territorial tax system means only profits earned from activities within Hong Kong are subject to profits tax. This is one of the most common and complex grounds for objection. You should challenge an assessment if:

• The IRD has assessed income that was derived entirely from offshore operations
• Core profit-generating activities (contract negotiation, service delivery, goods production) occurred outside Hong Kong
• You have previously received offshore status for similar operations, and circumstances haven’t changed
• The assessor failed to properly consider your offshore claim documentation

Key consideration: The IRD examines where deals are negotiated and where services or goods are delivered. Making high-level decisions (like pricing or marketing) in Hong Kong doesn’t automatically disqualify offshore status – the focus is on execution, not just planning. Each transaction is reviewed individually.

Important note: Following the EU’s review concluding that Hong Kong’s Foreign Source Income Exemption (FSIE) regime regarding passive income could be harmful, new requirements effective January 1, 2023, apply to multinational enterprise (MNE) groups. Specified foreign-sourced income is now exempt only if economic substance, participation, or nexus requirements are satisfied.

4. Deductions Incorrectly Disallowed

The IRD’s most common reason for disallowing deductions is insufficient evidence. You should object if legitimate business expenses were rejected, particularly when:

• You have proper documentation (receipts, invoices, contracts) supporting the expense
• The expense was wholly and exclusively incurred for producing assessable profits
• The assessor misclassified a revenue expense as capital in nature
• Industry-specific deductions were incorrectly denied
• The assessor applied inconsistent treatment compared to prior years

Common deduction disputes include:

• Bad debts: Only deductible once formally written off, not as general provisions
• Depreciation allowances: Disputes over asset classification and applicable rates
• Professional fees: Assessors sometimes challenge whether fees relate to capital or revenue matters
• Staff costs: Issues around benefits, bonuses, and related-party employment
• Mixed-purpose expenses: Where personal and business elements combine, often face scrutiny

5. Estimated Assessments Without Proper Basis

Under Section 59 of the Inland Revenue Ordinance, the IRD can issue an estimated assessment if you fail to provide proper documentation or submit a tax return. However, if you did file a proper return or can now provide the required documentation, you should object. When objecting to an estimated assessment, you must submit a properly completed tax return together with the accounts.

Key Indicators: When the Numbers Suggest You Should Challenge

The Cost-Benefit Analysis: Should You Challenge?

Even when valid grounds exist, business owners must weigh several practical factors before proceeding with an objection:

Financial Considerations

• Tax amount in dispute: Is the potential tax saving sufficient to justify professional fees and management time?
• Professional costs: Engaging tax advisors and potentially legal counsel can be expensive
• Interest on held-over tax: Currently 8.875% per annum (effective from January 1, 2024), accruing from the original due date
• Cashflow impact: Unless the Commissioner grants a holdover, you must pay the full amount while objecting

Probability of Success

• Strength of evidence: How robust is your documentation supporting the objection?
• Legal precedent: Have similar cases been decided in taxpayers’ favor?
• Complexity of issues: Straightforward factual errors have higher success rates than complex legal interpretations
• IRD’s position: Has the assessor provided detailed reasoning that may be difficult to counter?

Time and Resources

• Management attention: The objection process requires significant involvement from business principals
• Timeline: The IRD typically responds within 4 months, but complex cases can extend much longer
• Potential escalation: Are you prepared to appeal to the Board of Review if the Commissioner’s determination is unfavorable?

The Objection Process: What to Expect

Step 1: Filing Your Objection

You must lodge a written notice of objection stating precisely the grounds for your objection. You can:

• Complete Form IR831 (Notice of Objection / Application for Revision of Assessment)
• Submit via your eTax account online
• Mail to: P.O. Box 28777, Concorde Road Post Office, Hong Kong
• Fax to: 2877 1232

Critical requirement: State your grounds precisely and in detail. Vague objections are more likely to be rejected.

Step 2: Initial Review by Original Assessor

The objection is first considered by the original assessor. If the assessor agrees that changes should be made, the assessment will be revised accordingly and the case concludes. If not, the file is transferred to the IRD’s Appeals Section.

Step 3: Review by Appeals Section

The Appeals Section (a separate unit within the IRD) reviews the matter de novo (from the beginning) and prepares a statement of facts and draft reasons for the Commissioner or Deputy Commissioner’s consideration. During this stage, the IRD may request additional documentation or clarification.

Timeline: The IRD aims to issue notices of settlement or notifications of decision within 4 months from receipt of objections. Between May and August, replies typically come within 12 working days.

Step 4: Commissioner’s Determination

The Commissioner may confirm, reduce, increase, or annul the assessment. You will receive a written determination explaining the decision and the reasoning.

Step 5: Appeal to Board of Review (if necessary)

If you disagree with the Commissioner’s determination, you may appeal to the Board of Review within one month. The Board of Review is a statutory body independent of the IRD, often composed of members with legal qualifications and tax experience.

The appeal requires:

• Written notice to the Clerk of the Board of Review
• Statement of grounds of appeal supported by reasons
• Submission within one month of the Commissioner’s determination

The “Pay First, Argue Later” Principle

Hong Kong operates a “pay first, argue later” regime. This means that lodging an objection does not automatically suspend your obligation to pay the assessed tax. The tax remains payable on the date(s) specified in the assessment notice unless the Commissioner orders a holdover.

Types of Holdover

1. No holdover: Tax is payable immediately despite the objection
2. Unconditional holdover: Payment is suspended pending the objection outcome
3. Conditional holdover: Payment is suspended subject to providing security (bank guarantee, cash deposit, etc.)

The Commissioner has discretion in granting holdovers and typically considers:

• The merits of the objection
• The taxpayer’s financial position
• Payment history and compliance record
• Whether there’s a risk of non-recovery if the objection fails

Burden of Proof: Your Responsibility

A fundamental principle in Hong Kong tax disputes is that the taxpayer bears the burden of proving that the tax assessment is incorrect or excessive. There is no burden on the IRD to prove the assessment is correct.

This means you must:

• Provide concrete evidence supporting your position
• Demonstrate specific errors or misapplications of law
• Maintain comprehensive documentation substantiating your claims
• Present clear, logical arguments supported by facts and law

Merely asserting that the assessment is too high or that you disagree with the IRD’s approach is insufficient. You must prove your case with evidence.

Common Mistakes to Avoid

1. Missing the One-Month Deadline

This is the most critical error. Once the deadline passes, your options are severely limited. Set up calendar reminders immediately upon receiving an assessment.

2. Insufficient Grounds

Objections stating only “I disagree with the assessment” or “the amount is too high” without specific grounds will be rejected. You must articulate precisely why the assessment is wrong.

3. Inadequate Documentation

Claiming deductions or offshore status without proper supporting documents undermines your objection. Gather all evidence before filing.

4. Ignoring the Assessor’s Notes

The assessment notice often includes notes explaining adjustments. Understanding the IRD’s reasoning is essential to crafting an effective objection.

5. Going It Alone on Complex Issues

While simple factual corrections may not require professional help, complex legal issues, offshore claims, and significant amounts should involve experienced tax advisors.

6. Failing to Request a Holdover

If paying the assessed tax would cause financial hardship, explicitly request a holdover in your objection and explain your circumstances.

7. Not Preparing for Potential Appeal

If you’re serious about challenging the assessment, consider from the outset whether you’d be willing to appeal to the Board of Review if the Commissioner’s determination is unfavorable.

Professional Assistance: When to Seek Expert Help

While business owners can file objections themselves, professional assistance is strongly recommended when:

• The tax amount in dispute exceeds HK$100,000
• The issues involve complex legal interpretations
• You’re claiming offshore status for the first time
• The IRD has raised multiple adjustment issues
• Previous objections have been unsuccessful
• The case may proceed to the Board of Review
• You lack experience with IRD objection procedures

Tax professionals can:

• Assess the strength of your case objectively
• Identify all valid grounds for objection
• Prepare comprehensive, well-documented submissions
• Negotiate with the IRD on your behalf
• Navigate procedural requirements correctly
• Advise on holdover applications
• Represent you before the Board of Review if necessary

Case Study Examples

Example 1: Offshore Income Challenge – Successful

A Hong Kong trading company received an assessment including profits from sourcing products from mainland China and selling to European customers. All contracts were negotiated and concluded outside Hong Kong, with goods shipped directly from China to Europe.

Challenge basis: Offshore income wrongly assessed

Evidence provided: Contracts showing overseas negotiation, shipping documents, correspondence with clients and suppliers conducted outside Hong Kong, bank records showing offshore receipts

Outcome: IRD Appeals Section agreed the profits were offshore-sourced. Assessment reduced by HK$2.8 million, saving approximately HK$460,000 in tax.

Example 2: Deduction Disallowance – Partially Successful

A professional services firm had HK$380,000 in staff training expenses disallowed as the IRD considered them capital in nature.

Challenge basis: Training expenses were revenue in nature, wholly incurred for producing assessable profits

Evidence provided: Training program details showing skills enhancement for current roles (not new skills for new business ventures), invoices, attendance records, business rationale

Outcome: IRD accepted HK$280,000 as revenue expenses but maintained that HK$100,000 related to long-term business expansion (capital). Net tax saving: approximately HK$46,000.

Example 3: Factual Error – Successful

A manufacturing company’s assessment showed revenue of HK$15.8 million, but actual audited revenue was HK$12.3 million. The IRD had included a large contract twice due to an administrative error.

Challenge basis: Factual error – double counting of revenue

Evidence provided: Audited financial statements, sales ledger, contract documentation

Outcome: Original assessor immediately agreed to the correction. Revised assessment issued within three weeks. Tax saving: approximately HK$575,000.

Conclusion

Challenging a Hong Kong tax assessment is a significant decision that requires careful consideration of both the legal merits and practical implications. While the IRD’s assessors generally apply tax law correctly, errors do occur, and legitimate disputes arise over factual matters, offshore income, deductions, and legal interpretations.

Business owners should view the objection process not as confrontational but as a legitimate mechanism for ensuring accurate tax assessments. The key to success lies in acting within the strict time limits, articulating clear grounds supported by robust evidence, and seeking professional assistance when complexity or significant amounts are involved.

By understanding when to challenge an assessment and how to navigate the objection process effectively, you can protect your company’s financial interests while maintaining a constructive relationship with the Inland Revenue Department.
