Have you ever logged into your eTAX account to find an official notification from the Inland Revenue Department (IRD) and wondered what to do next? In Hong Kong's increasingly digital tax environment, understanding how to properly receive, interpret, and respond to IRD communications through the eTAX platform has become essential for every taxpayer. Whether you're receiving your first tax return or dealing with a complex assessment query, knowing the proper procedures and deadlines can save you from penalties, additional charges, and unnecessary stress.
Understanding Hong Kong's eTAX Notification System
The eTAX platform is Hong Kong's comprehensive digital tax portal, launched by the Inland Revenue Department to streamline tax administration and communication. The enhanced 2024/25 version features an intuitive, mobile-responsive design that allows taxpayers to manage their obligations from any device—desktop, tablet, or smartphone.
eTAX Message Box Structure
The eTAX notification center is organized into two primary sections that keep all your tax communications centralized and accessible:
| Message Section | Purpose | Content |
|---|---|---|
| Inbox | Receive communications | Messages from IRD and messages sent by authorized representatives via Tax Representative Portal (TRP) |
| Outbox | Track sent communications | Messages sent by you to IRD via the Individual Tax Portal (ITP) |
All electronic notices and documents are retained in the Message Box for 6 years from the date of issue, providing you with a comprehensive archive of your tax communications. You can also enable email notifications to alert you when new messages arrive in your inbox.
Types of Alert Messages You'll Receive
- Return Filing Reminders: Approximately one week before the return filing due date, you'll receive an alert message with links to view the electronic notice and file your return online
- Payment Due Alerts: About one week before the tax payment due date, an e-alert reminds you of your tax liability for Salaries Tax, Property Tax, Profits Tax, or Personal Assessment
- Payment Receipts: Electronic receipts are sent to your inbox within approximately 2 working days after the IRD receives your payment
- Assessment Notices: Official notifications of tax assessments and determinations
Types of IRD Communications and How to Respond
1. Tax Returns (Form BIR60 for Individuals)
Tax returns are issued annually to taxpayers, requiring them to declare their income and claim relevant deductions. For the 2024/25 tax year, individual tax returns were typically issued in early May.
| Taxpayer Type | Standard Deadline | Electronic Filing Extension |
|---|---|---|
| Individuals | 1 month from issue date | Automatic 1-month extension |
| Sole Proprietors | Extended deadline (typically August) | Available through tax representatives |
- Log in to eTAX: Access your Individual Tax Portal (ITP) account immediately upon receiving notification
- Review the Notice: Check your Message Box inbox for the tax return notice
- Gather Documentation: Collect all relevant income documentation, receipts for deductions, and supporting records
- Complete Electronically: Fill out the return through the eTAX platform to benefit from the automatic extension
- Review Carefully: Double-check all entries before submission
- Submit and Retain: Submit before the deadline and keep the acknowledgment receipt
2. Demand Notes (Tax Bills)
A tax demand note is an official document issued by the IRD notifying taxpayers of their tax obligations and payment requirements. This document demands immediate attention, as non-compliance can result in penalties, surcharges, and legal consequences.
- Review Carefully: Verify the assessed amount and payment details
- Arrange Payment: If you agree with the assessment, pay before the due date using eTAX payment services, PPS, internet banking, or other approved methods
- Object if Disagreeing: If you disagree with the assessment, prepare and submit a written objection within 1 month
- Keep Records: Maintain copies of all payment receipts or objection submissions
3. Enquiry Letters and Information Requests
The IRD may issue enquiry letters requesting additional information, clarification, or supporting documentation regarding your tax affairs. These may relate to specific deductions claimed, sources of income, or general compliance reviews.
| Response Requirement | Details |
|---|---|
| Standard Deadline | Typically 1 month from the date of the enquiry letter |
| Extension Requests | Submit as soon as possible with reasonable explanation if more time is needed |
| Complete Response | Provide all requested information and supporting documents |
| Document Upload | Upload up to 5 supporting documents (total file size up to 200MB) via eTAX |
The Objection and Appeal Process: Your Rights as a Taxpayer
Hong Kong's tax objection and appeal system is governed by Sections 64-66 of the Inland Revenue Ordinance and provides a structured pathway for taxpayers who disagree with IRD assessments or determinations.
Stage 1: Objection to the Commissioner (Section 64)
When an assessment is issued, you have the right to object within one month of the date of the notice of assessment. This is the mandatory first step in challenging any assessment.
| Requirement | Details |
|---|---|
| Timing | Submit within 1 month of the assessment notice date |
| Format | Written notice (no prescribed form, but must be in writing) |
| Content | Detailed grounds explaining precisely why you object to the assessment |
| Supporting Evidence | Include relevant documentation and facts supporting your position |
Applying for Holdover of Tax
To avoid undue financial hardship while your objection is being considered, you can apply to the Commissioner for a holdover of the disputed tax amount.
| Aspect | Details |
|---|---|
| Authority | Commissioner has wide discretion to grant or refuse holdover |
| Security Requirements | May require purchase of tax reserve certificate or banker's undertaking |
| Interest Rate | 8.25% per annum on held-over tax (from July 2025) |
| Application Timing | Should be submitted together with or shortly after the objection |
Stage 2: Appeal to the Board of Review (Sections 65-66)
If you disagree with the Commissioner's determination of your objection, you can appeal to the Board of Review, an independent statutory tribunal constituted under Section 65 of the IRO.
| Appeal Requirement | Details |
|---|---|
| Timing | Within 1 month after receiving the Commissioner's written determination |
| Format | Written notice of appeal to the Board of Review with copy to the Commissioner |
| Required Documents | Statement of grounds of appeal and copies of the Commissioner's determination |
| Nature | The Board acts as an independent trial court conducting de novo hearings |
Record Retention Requirements: The 7-Year Rule
Maintaining proper records is not just good business practice—it's a legal requirement in Hong Kong that directly affects your ability to respond to IRD communications and substantiate your tax positions.
The 7-Year Rule Under Section 51C
Under Section 51C of the Inland Revenue Ordinance, all taxpayers must retain business and tax records for a minimum of 7 years from the date of the transaction. This requirement applies to both businesses and individuals with rental or business income.
| Record Category | Examples |
|---|---|
| Financial Statements | Income statements, balance sheets, cash flow statements |
| Transaction Records | Sales invoices, purchase receipts, bank statements, daily transaction logs |
| Asset and Liability Records | Property purchase documents, loan agreements, depreciation schedules |
| Employment Records | Payroll records, IR56 forms, employment contracts, MPF records |
| Supporting Documentation | Expense vouchers, receipts, contracts, correspondence |
| Violation | Penalty |

| Failing to maintain records for 7 years | Maximum fine of HK$100,000 |
| Unable to produce records during audit | Disallowance of deductions, reassessment of tax liabilities, additional tax charges |
| Late filing of tax return | Up to HK$10,000 plus additional tax up to 3x unpaid amount (Section 51 IRO) |
