How to Register for eTAX

Registering for eTAX requires your personal details and identification. You can register online using your Hong Kong identity card number and other identifying information, or you may request an invitation code from the IRD by calling their customer service hotline. Once registered, you will receive a user account credentials email with instructions to activate your account. The IRD recommends using a strong, unique password and enabling two-factor authentication where available. After activation, you can log in using your eTAX account number and password to access all IRD services.

Filing Individual Tax Returns

Filing your individual tax return on eTAX is straightforward. After logging in, select the tax year and the type of return you wish to file. For most individuals, this is the Salaries Tax Return (BIR60). You can enter your employment income, MPF contributions, personal allowances, and allowable deductions directly in the eTAX interface. The system will automatically calculate your tax under both the progressive rate and standard rate, showing which is more favorable. You can save a draft return and return to it later before submission. Once submitted, you will receive an electronic confirmation.

Viewing Your Assessment

After submitting your tax return, you can view your assessment notice online through eTAX. The assessment notice shows your total assessable income, deductions, taxable income, tax payable under both rate systems, and any provisional tax due. Review the assessment carefully to ensure all allowances and deductions were correctly applied. If you notice an error, you can notify the IRD through eTAX or in writing. For complex corrections, you may need to provide additional supporting documents. Our Hong Kong tax allowances and deductions guide can help you verify your assessment calculations.

Paying Tax Online

eTAX supports multiple electronic payment options. You can pay using a credit card, PPS, or bank transfer through the IRD's secure payment portal. Payments made through eTAX are instantly reflected in your tax account. You can also authorize automatic payments or set up recurring payments for provisional tax installments. Always keep a record of your payment confirmation for future reference. If you are unsure about the amount due, check your assessment notice or use our Hong Kong tax calculator to estimate your liability before paying.

Holdover Applications

If you anticipate that your income will decrease in the coming year, you can apply for a holdover of provisional tax through eTAX. The application requires you to provide an estimate of your expected income for the next year and supporting evidence, such as a contract of employment or financial projection. The IRD will review your application and notify you of the outcome. A successful holdover reduces your immediate financial burden and aligns your payments with your actual tax liability. See our Hong Kong provisional tax guide for more on when to apply.

Common eTAX Issues

• Account access problems: If you have forgotten your password, use the account recovery option. Contact the IRD if you encounter persistent login issues.
• Failed submissions: Ensure all required fields are completed and all supporting documents are attached before submitting. Save drafts to avoid losing work.
• Incorrect assessment: If eTAX displays an assessment you believe is wrong, submit an objection through the system or in writing within one month of the notice date.
• Payment not reflected: Payments may take up to three business days to appear. If the delay persists, check your bank statement and contact the IRD with your payment reference number.
