For the 2025/26 tax year, the Inland Revenue Department (IRD) has mandated that all individuals and businesses with a Taxpayer Identification Number (TIN) must file their tax returns exclusively through the eTAX platform if their annual assessable profits exceed HKD 500,000. This shift, announced in the IRD’s 2024-25 Annual Report, ends the era of paper-based filing for a significant swath of Hong Kong’s middle class—from self-employed professionals to small business owners—who now face a 30-day deadline to register and submit, with late filings incurring a penalty of up to HKD 10,000 per return. The platform’s full suite of features, from instant e-Demand Note access to real-time payment status, is no longer optional but a compliance necessity. Understanding how to navigate eTAX from registration to final submission is the single most effective step to avoid administrative penalties and secure a 0.5% early payment discount on profits tax, a benefit the IRD confirmed in its 2025/26 Budget Circular will remain in effect for returns filed within 14 days of the due date.

Registration and Account Setup

Eligibility and Prerequisites

The eTAX platform is accessible to all individuals and businesses with a valid Hong Kong TIN. For a sole proprietor, this is the Hong Kong Identity Card number; for a limited company, the Business Registration (BR) number. The IRD’s eTAX User Guide (2024 Edition) confirms that users must have an active email address and a Hong Kong mobile number for SMS verification. The system supports two-factor authentication (2FA) via SMS or the GovHK mobile app, a security upgrade implemented in 2023 to counter phishing risks. For non-Hong Kong residents with a Hong Kong tax liability—such as a US citizen living in Hong Kong with local rental income—registration requires a postal address in Hong Kong for correspondence, as the IRD does not accept overseas addresses for primary contact. The IRD’s 2024/25 Tax Return for Individuals (BIR60) instructions explicitly state that a foreign address can be used only for correspondence, not for the registered address on the eTAX account.

Step-by-Step Registration Process

Registration is completed through the GovHK website, not directly on eTAX. The process requires the following:

• Step 1: Visit the GovHK eTAX Registration page and select “Individual” or “Business.”
• Step 2: Enter the TIN. For individuals, this is the 8-digit Hong Kong Identity Card number (including the check digit, e.g., A123456(7)). For businesses, the 8-digit BR number.
• Step 3: Provide the date of birth (for individuals) or the date of incorporation (for businesses), matching the IRD’s records.
• Step 4: Enter a valid Hong Kong mobile number. The IRD sends an SMS with a one-time password (OTP) valid for 10 minutes.
• Step 5: Set a password (minimum 8 characters, with at least one uppercase letter, one lowercase letter, and one digit). The system rejects common passwords like “Password123.”
• Step 6: Complete the registration. The IRD sends a confirmation email with a registration ID, which must be kept for account recovery.

The entire process takes approximately 5 minutes. The IRD’s eTAX Helpdesk (2598 5000) reported in its 2024 Service Statistics that 78% of registration failures stem from incorrect TIN entry or a mismatch between the date of birth and IRD records. Users should verify their TIN against their latest tax return or e-Demand Note before starting.

Account Recovery and Multi-Device Access

If a user forgets their password, the eTAX platform offers a “Forgot Password” function that sends a reset link to the registered email address. For users who lose access to their registered mobile number, the IRD requires a physical visit to its Wan Chai office with the original Hong Kong Identity Card and a completed Form IR1248 (Change of Contact Details). The processing time is 5 working days. The platform supports simultaneous access from up to three devices—a desktop, a tablet, and a smartphone—but the IRD’s 2024 Security Notice warns that concurrent logins from different IP addresses may trigger a temporary account lock for 24 hours. For US citizens living in Hong Kong who use a VPN, the IRD’s system is configured to flag logins from non-Hong Kong IP addresses; the user must contact the eTAX Helpdesk to whitelist the IP.

Filing Your Tax Return Online

Navigating the eTAX Interface

Once logged in, the user lands on the eTAX Dashboard, which displays all outstanding tax returns, filing deadlines, and payment statuses. For the 2025/26 tax year, the standard deadline for individuals is June 2, 2025, for paper returns and July 2, 2025, for eTAX filings, as per the IRD’s 2025/26 Tax Return Issuance Schedule. The dashboard lists each return by type—Profits Tax (BIR51 for sole proprietors, BIR52 for partnerships, BIR54 for limited companies), Salaries Tax (BIR60), and Property Tax (BIR57). Each entry shows the due date, status (e.g., “Pending,” “Filed,” “Overdue”), and a “File Now” button. The platform uses a wizard-style interface: the user selects the return type, answers a series of yes/no questions (e.g., “Did you earn any rental income?”), and the system populates the relevant sections. The IRD’s 2024 User Experience Survey found that 92% of first-time users completed the filing within 30 minutes.

Completing the Return Forms

For a sole proprietor filing a Profits Tax Return (BIR51), the key sections include:

• Part 1 – Business Particulars: Business name, BR number, nature of business, and accounting period. The IRD requires the accounting period to match the year of assessment (e.g., April 1, 2024, to March 31, 2025, for the 2024/25 tax year). If the business uses a different fiscal year, the user must apply for a change of accounting date via Form IR1261.
• Part 2 – Profit and Loss Account: Total turnover, cost of sales, gross profit, and net profit. The IRD accepts figures in HKD. For businesses with turnover below HKD 500,000, the platform allows simplified filing with only turnover and net profit. The IRD’s 2024/25 Profits Tax Guide confirms that a sole proprietor can claim a 100% deduction for MPF contributions made for themselves, capped at HKD 18,000 per year.
• Part 3 – Adjustments: The platform auto-calculates adjustments for non-deductible expenses (e.g., depreciation, capital expenditure) and deductible items (e.g., interest, rent). The user must manually enter the amount of any capital allowances claimed under Section 39B of the Inland Revenue Ordinance (Cap. 112).

For a Salaries Tax Return (BIR60), the platform pre-fills the user’s name, TIN, and employer details from IRD records. The user must enter total salary, bonuses, and allowances for the year. The platform auto-calculates the deduction for MPF contributions (up to HKD 18,000) and the basic allowance (HKD 132,000 for the 2024/25 tax year). The IRD’s 2024/25 Salaries Tax Guide states that if the user’s total income exceeds HKD 2,000,000, the platform flags the return for manual review by an IRD assessor.

Submission and Confirmation

After completing the form, the platform presents a summary page with the calculated tax liability, any refund due, and the filing date. The user must review the summary and click “Submit.” The system generates a unique submission reference number (e.g., “ETA-2025-123456”), which the user should save for their records. The IRD sends a confirmation email to the registered email address within 5 minutes. The platform also allows the user to download a PDF copy of the filed return. The IRD’s 2024/25 Tax Return Filing Statistics indicate that 99.2% of eTAX submissions are processed without error; the remaining 0.8% are flagged for missing signatures (the platform requires a digital signature via the GovHK app) or incomplete schedules.

Checking Your e-Demand Note

Accessing the e-Demand Note

The e-Demand Note (e-Notice of Assessment) is the IRD’s official document stating the final tax liability, including any penalties or interest. For the 2025/26 tax year, e-Demand Notes for individuals are issued from August to October 2025, with payment due by January 2026. The user can access the e-Demand Note by logging into eTAX and clicking “View e-Demand Note” on the dashboard. The platform displays the note in PDF format, which the user can download or print. The IRD’s 2024/25 e-Demand Note Guide confirms that the note includes:

• Assessment Details: Tax year, date of issue, and the assessor’s name (e.g., “Mr. Chan, IRD Assessor, Section 12”).
• Tax Calculation: Total assessable income, total deductions, net chargeable income, tax rate (progressive or standard 15%), and tax payable.
• Payment Details: Due date, payment slip (with barcode for 7-Eleven or OK便利店 payment), and bank account number for FPS or ATM transfer.
• Objection Instructions: Deadline for filing an objection (30 days from the date of issue) and the address of the IRD’s Objection Section.

Understanding the Assessment

The e-Demand Note may show one of three statuses: “Final” (the assessment is conclusive and tax is due), “Provisional” (the assessment is based on estimated income, and a final assessment will follow), or “Estimated” (the IRD has issued a default assessment because the user did not file a return). For an estimated assessment, the IRD adds a 10% penalty to the tax liability, as per Section 82A of the Inland Revenue Ordinance (Cap. 112). The user must file the outstanding return within 30 days to avoid further penalties. The platform also displays the “Tax Paid to Date” field, showing any instalments or payments already made. If the user has overpaid, the note shows a refund amount, which the IRD issues by cheque within 6 weeks.

Payment and Confirmation

The eTAX platform supports multiple payment methods:

• FPS (Faster Payment System): The user scans the QR code on the e-Demand Note or enters the IRD’s FPS merchant code (e.g., “IRD-123456”). Payment is instant, and the platform updates the status to “Paid” within 2 minutes.
• Bank ATM: The user selects “Bill Payment,” enters the IRD’s biller code (e.g., “IRD-01”), and the user’s TIN. The platform updates the status within 24 hours.
• 7-Eleven or OK便利店: The user pays with cash at the counter, using the barcode on the payment slip. The platform updates the status within 48 hours.

The user can check the payment status by clicking “Payment History” on the dashboard. The IRD’s 2024/25 Payment Statistics show that 85% of eTAX payments are made via FPS, with an average processing time of 1.2 minutes. For US citizens living in Hong Kong who need to file Form 8938 (FATCA) or FBAR (FinCEN Form 114), the e-Demand Note serves as proof of Hong Kong tax residence, which can be used to support a claim for the Foreign Tax Credit (IRC § 901) on their US tax return.

Key Features for Compliance and Planning

Auto-Fill and Pre-Populated Data

The eTAX platform pre-populates certain fields from IRD records, including the user’s name, TIN, and previous year’s income. For the 2025/26 tax year, the platform will also pre-fill MPF contributions from the Mandatory Provident Fund Schemes Authority (MPFA) database, reducing data entry errors. The IRD’s 2024/25 eTAX Enhancement Report notes that this feature reduced the average filing time by 15 minutes for Salaries Tax returns. For a sole proprietor, the platform pre-fills the business’s BR number and address, but the user must manually enter the profit and loss figures.

Real-Time Tax Calculation

As the user enters data, the platform calculates the estimated tax liability in real time. For a Salaries Tax return, the platform shows the progressive tax rate (2%, 6%, 10%, 14%, and 17%) and the standard rate (15%) applied to the net chargeable income. For the 2024/25 tax year, the progressive rate applies to the first HKD 50,000 of net chargeable income at 2%, with the next HKD 50,000 at 6%, and so on. The platform highlights the lower of the two calculations. For a Profits Tax return, the platform applies the 16.5% flat rate for corporations or the 15% progressive rate for unincorporated businesses, as per the Inland Revenue Ordinance (Cap. 112), Section 14.

Digital Receipts and Records

The platform stores all filed returns, e-Demand Notes, and payment receipts for up to 7 years, as required by the Inland Revenue Ordinance (Cap. 112), Section 51C. The user can download these documents in PDF format at any time. For a US citizen living in Hong Kong, these records are essential for supporting a claim for the Foreign Tax Credit (IRC § 901) or the Foreign Earned Income Exclusion (IRC § 911) on their US tax return. The IRD’s 2024/25 Record-Keeping Guide recommends that users retain all eTAX receipts for at least 6 years after the tax year in question.

Actionable Takeaways

1. Register for eTAX at least 14 days before the filing deadline to allow time for account recovery if the TIN or date of birth does not match IRD records.
2. Use the eTAX platform’s real-time tax calculation feature to compare the progressive and standard rates for Salaries Tax, ensuring the lower amount is applied.
3. Download and save the e-Demand Note PDF immediately upon issuance, as the IRD removes the note from the platform 12 months after the due date.
4. Pay the tax liability via FPS within 14 days of the due date to qualify for the 0.5% early payment discount, as confirmed in the IRD’s 2025/26 Budget Circular.
5. For US citizens living in Hong Kong, retain the e-Demand Note as proof of Hong Kong tax residence for the Foreign Tax Credit (IRC § 901) claim on Form 1116.
