How to Use Hong Kong’s eTAX Portal for Provisional Tax Payments

Hong Kong’s Inland Revenue Department (IRD) has revolutionized tax administration with its comprehensive eTAX system, particularly for managing provisional tax obligations. As of July 22, 2025, the IRD launched three newly redesigned tax portals under the eTAX umbrella: the Individual Tax Portal (ITP), Business Tax Portal (BTP), and Tax Representative Portal (TRP). These platforms offer taxpayers a secure, efficient, and mobile-responsive solution for managing their provisional tax payments and holdover applications.

This comprehensive guide will walk you through everything you need to know about using Hong Kong’s eTAX portal for provisional tax payments, including payment methods, holdover applications, deadlines, and the latest 2025 features designed to streamline your tax compliance.

Understanding Hong Kong’s Provisional Tax System

Before diving into the eTAX portal functionality, it’s essential to understand what provisional tax means in the Hong Kong context. Unlike many jurisdictions that collect tax through regular withholding, Hong Kong operates on a provisional tax system that serves as an estimated prepayment of your next year’s tax liability.

What is Provisional Tax?

Provisional tax is not a separate tax but rather an advance payment toward your tax liability for the current year of assessment. When the IRD issues your tax assessment, it typically includes two components:

• Final Tax: The actual tax liability for the completed assessment year based on your actual income
• Provisional Tax: An estimated tax for the upcoming year, normally based on the assessable income from the preceding year

This system ensures that the government receives tax revenue throughout the year while providing taxpayers with a structured payment schedule.

Payment Structure and Timeline

Provisional tax payments are divided into two installments with specific percentages allocated to each:

Important Note: Exact deadlines vary each year. Always refer to your IRD demand note for the official payment dates specific to your assessment. For the 2024/25 year of assessment, individuals received their tax returns on May 2, 2025, with the standard filing deadline of June 2, 2025 (or July 2, 2025 for electronic submissions).

The New eTAX Portal System (2025)

On July 22, 2025, the IRD launched a completely redesigned eTAX platform featuring three specialized portals designed to enhance efficiency and user experience. This major upgrade introduced responsive web design, making tax management accessible from any device.

The Three New Tax Portals

2025 Platform Features

The new eTAX portals incorporate several innovative features designed to streamline tax administration:

• Mobile Responsiveness: Fully responsive design accessible via desktop, tablet, or smartphone through the dedicated “eTAX” mobile application launched July 22, 2025
• iAM Smart Integration: Secure login via iAM Smart/iAM Smart+ for enhanced security and convenience
• Pre-saved Deductions: Automatically pre-fill future tax returns with saved deduction details (charitable donations, MPF contributions, etc.)
• Document Upload Capability: Upload up to 5 supporting documents (200MB total) for amendment requests and holdover applications
• Instant Acknowledgements: Receive immediate confirmation when submitting applications or payments
• User Profile Migration: Existing eTAX users’ profiles have been automatically migrated to the new ITP

How to Pay Provisional Tax Through eTAX

The eTAX portal offers multiple convenient payment methods designed to accommodate different preferences and banking relationships. All payment methods are secure and provide instant confirmation when processed successfully.

Electronic Payment Methods

Step-by-Step: Making a Payment via eTAX Portal

1. Log into the Individual Tax Portal: Access the ITP at etax.ird.gov.hk using your login credentials or iAM Smart authentication
2. Navigate to Payment Section: Select “View Tax Position” or “Make Payment” from the main menu
3. Select Outstanding Amount: Review your provisional tax assessment and select the amount to pay (first or second installment)
4. Choose Payment Method: Select your preferred payment method from the available options
5. Complete Transaction: Follow the prompts for your chosen payment method (e.g., scan FPS QR code, enter PPS details, or proceed to internet banking)
6. Receive Confirmation: An e-receipt will be issued through your eTAX account upon successful payment

Important: If the first installment is not paid by the due date, the second installment becomes immediately due, and the entire balance will be deemed in default. This triggers a 5% surcharge on the total amount, with an additional 10% surcharge applied after 6 months of non-payment.

Applying for Holdover of Provisional Tax

One of the most valuable features of the eTAX portal is the ability to apply for a holdover (reduction or deferral) of provisional tax when your income is expected to decrease. This prevents overpayment and improves cash flow management.

Eligibility Criteria for Holdover

You may apply for a holdover of provisional tax if any of the following circumstances apply:

• Reduced Income (Most Common): Your net chargeable income for the current year is expected to be less than 90% of your net chargeable income for the preceding year (i.e., a drop of more than 10%)
• Cessation of Income: You have ceased, or will cease before the end of the year of assessment, to derive income chargeable to salaries tax or profits tax
• Additional Allowances: You have become entitled to an allowance that was not included in the provisional tax notice (e.g., child allowance for a newborn, dependent parent allowance)
• Objection to Previous Assessment: You have formally objected to your tax assessment for the year preceding the provisional tax year

Critical Deadlines for Holdover Applications

Timing is crucial when applying for a holdover. The law provides a two-tier deadline system:

Example: 2025/26 Holdover Application Timeline

Assume you received your tax demand note on August 5, 2025, with provisional salaries tax installments due on:

• 1st installment: January 2, 2026
• 2nd installment: April 1, 2026

For the 1st installment:

• 28 days before payment due: December 5, 2025
• 14 days after demand note: August 19, 2025
• Deadline: December 5, 2025 (the later date)

For the 2nd installment:

• 28 days before payment due: March 4, 2026
• 14 days after demand note: August 19, 2025
• Deadline: March 4, 2026 (the later date)

Recommended timing: Most taxpayers should apply for holdover in November-December 2025 for the first installment to allow sufficient time for IRD processing.

How to Apply via eTAX Portal

1. Access the Individual Tax Portal: Log in to the ITP using your credentials or iAM Smart
2. Navigate to Holdover Section: Select “Apply for Holdover of Provisional Tax” from the main menu
3. Select Tax Type and Year: Choose the relevant tax type (Salaries Tax or Profits Tax) and year of assessment
4. Specify Grounds for Application: Indicate the reason for holdover (reduced income, additional allowances, cessation of income, etc.)
5. Provide Income Estimate: Enter your estimated net chargeable income for the current year with detailed computation showing the expected decrease
6. Upload Supporting Documents: Attach relevant evidence (employment termination letter, profit forecasts, birth certificates for newborns, etc.) – up to 5 documents, 200MB total
7. Review and Submit: Carefully review all information before submitting
8. Receive Acknowledgement: You’ll receive an instant acknowledgement notification through the portal
9. IRD Review: The IRD will review your application and issue a revised assessment or request additional information

Alternative Application Methods

If you prefer not to use the eTAX portal, you can apply via:

• Form IR1121: Complete and submit the official holdover application form
• Mail: P.O. Box 28487, Concorde Road Post Office, Kowloon, Hong Kong
• Fax: 2519 6896
• Enquiry Hotline: 187 8011

Note: You must complete one Form IR1121 for each tax type for which you’re applying for holdover.

Required Documentation

The strength of your holdover application depends on the quality of supporting documentation:

Consequences of Late or Non-Payment

Understanding the penalties for late payment is crucial for maintaining tax compliance and avoiding unnecessary financial burdens.

Surcharges and Penalties

Late Filing Penalties (2025)

Hong Kong has implemented stricter penalties for overdue tax return submissions:

• First Offense: HK$1,200 penalty; increases to HK$3,000 if unresolved within 14 days
• Repeat Offense: Immediate HK$3,000 penalty; increases to HK$8,000 if unresolved within 14 days
• Continued Non-Compliance: Fines up to HK$50,000, recovery of three times the unpaid tax amount, criminal charges including imprisonment, and potential travel restrictions

Best Practices for Managing Provisional Tax

Effective provisional tax management can significantly improve cash flow and reduce compliance stress. Here are expert recommendations:

1. Set Up Your eTAX Account Early

Don’t wait until tax season. Register for the Individual Tax Portal well in advance to familiarize yourself with the interface and ensure all your information is current. Existing users’ profiles have been migrated to the new 2025 platform, but verify your details are accurate.

2. Monitor Income Changes Throughout the Year

Keep track of significant income changes that might qualify you for holdover. If you anticipate a drop of more than 10% in your net chargeable income, start gathering documentation early. This is particularly important for:

• Self-employed individuals with variable income
• Employees expecting pay cuts, reduced bonuses, or job changes
• Individuals planning to leave Hong Kong
• Those experiencing life changes (new children, newly dependent parents)

3. Apply for Holdover at the Optimal Time

While you have until 28 days before the payment due date (or 14 days after the demand note), applying in November-December for January payments gives the IRD adequate time to process your application and issue a revised assessment before the due date.

4. Utilize Pre-Saved Deduction Features

Take advantage of the 2025 portal’s ability to pre-save deduction details. Enter your regular deductions (MPF contributions, charitable donations, home loan interest, etc.) once, and they’ll automatically populate in future returns, reducing errors and time spent on filing.

5. Keep Detailed Records

Maintain organized records of all income, deductions, and supporting documents. The ability to upload up to 5 documents (200MB total) means you can provide comprehensive evidence for holdover applications directly through the portal.

6. Choose the Right Payment Method

Select payment methods that align with your preferences:

• For convenience: FPS via QR code or e-wallet
• For 24/7 access: PPS or internet banking
• For small amounts: Convenience stores (up to HK$5,000)
• For record-keeping: Internet banking (provides detailed transaction records)

7. Download E-Receipts for Tax Records

E-receipts issued through the eTAX portal serve as official proof of payment. Download and save these receipts for your records, particularly for business expense documentation.

8. Use Mobile Access for On-the-Go Management

With the 2025 mobile-responsive design and dedicated eTAX mobile application, you can check tax positions, make payments, and submit applications from anywhere. This is particularly useful for busy professionals and frequent travelers.

Common Questions and Troubleshooting

What if my holdover application is rejected?

If the IRD rejects your holdover application or approves only a partial reduction, you must pay the provisional tax as assessed (or as revised). You can request a review by providing additional documentation or explaining your circumstances in more detail. Importantly, you should still pay any amount not held over by the due date to avoid surcharges.

Can I apply for installment payment plans?

Yes, the IRD offers payment by installments in cases of financial hardship. Contact the Holdover of Provisional Tax or Payment by Instalments Application Hotline at 187 8011 to discuss your options. This is separate from the standard two-installment provisional tax structure and requires special approval.

What happens if I over-estimated my income decrease?

If your actual income for the year turns out to be higher than your holdover estimate, you’ll need to pay the difference when your final assessment is issued. While there’s no specific penalty for underestimating your income decrease, significant or repeated discrepancies may lead to closer scrutiny of future holdover applications.

How long does it take for the IRD to process holdover applications?

Processing times vary depending on the complexity of your application and the volume of applications the IRD is handling. Simple cases with complete documentation can be processed within 2-3 weeks. More complex cases requiring additional information may take longer. This is why applying well before the deadline is recommended.

Can I access eTAX services if I’m overseas?

Yes, the eTAX portal is accessible from anywhere in the world with an internet connection. The mobile application and responsive design make it particularly convenient for managing tax obligations while traveling or living abroad temporarily.
