The consequences of filing a tax return late may be more serious than you expect—and extend beyond a fine.
As a Hong Kong business owner or individual taxpayer, have you ever missed a tax return deadline because of a busy schedule, or worried about the consequences of filing late? This article explains the penalties, effects and remedies for late tax returns, helping you manage your tax affairs and avoid unnecessary legal and financial risks.
Legal Consequences and Penalties for Late Tax Returns
The Inland Revenue Department may prosecute anyone who, without reasonable excuse, commits any of the following acts under section 80(2):
(i) Makes an incorrect tax return, or causes or allows someone else to make an incorrect return on their behalf;
(ii) Makes an incorrect statement in connection with a claim for a deduction or allowance;
(iii) Gives incorrect information concerning any matter affecting their own or another person’s tax liability;
(iv) Fails to notify the Inland Revenue Department of a premium refund after claiming a deduction for premiums paid under a Voluntary Health Insurance Scheme policy or a qualifying deferred annuity policy;
(v) Fails to submit a tax return on time; or
(vi) Fails to notify the Inland Revenue Department of a liability to tax.
An offence may result in a fine of $10,000 and an additional fine of 3 times the amount of tax undercharged. For the offence in item (v), the court may also order the convicted person to submit a tax return within a specified period.
Applying for a Filing Extension
If a business cannot submit its tax return on time, it must apply to the Inland Revenue Department for an extension. It is advisable to apply 1 to 2 months before the deadline and explain the reasons in detail. The department will assess the application on its circumstances, and the extension period will depend on the business’s situation.
The Process for Addressing a Late Tax Return
Businesses may apply in writing or through GovHK using its eTAX platform, specifying the extension required. Clearly explaining the reason for the extension is key to a successful application. Please also note the following:
- Check your eligibility for an extension: assess whether the delay was unavoidable. Serious illness or hospitalisation, the death of an immediate family member, or business travel or time overseas that prevents timely filing may be considered reasonable grounds.
- Prepare the required documents: write an extension request including your personal details, such as name, identity card number, contact information and year of assessment, financial statements and audit report, and an explanation for the delay. Attach relevant supporting documents.
- Submit the application promptly: send the extension request and supporting documents to the Inland Revenue Department by post, in person or by fax.
- Follow up: wait for the department’s reply after submitting the application. If you apply close to the deadline, call its hotline to confirm receipt and check progress.
Seeking Professional Tax Assistance
Seeking help from a professional accountant is one of the best ways to address a late tax return. An accountant can clarify the reasons for the delay, check that documents are accurate and provide assistance in several areas:
- Applying for an extension: a professional accountant can prepare the application documents and provide a reasonable explanation to improve the likelihood of approval
- Calculating penalties and interest: accurately calculate the penalties and interest the business may face and help arrange prompt payment to prevent further penalties
- Handling tax recovery notices: if a recovery notice has been received, an accountant can help the business communicate with the Inland Revenue Department about instalments or other solutions
