Hong Kong Tax Deadline Calendar 2025: Filing Dates and Provisional Tax

Missing a Hong Kong tax deadline can result in surcharges, penalties, and even legal action. The Inland Revenue Department operates on a strict calendar for issuing tax returns, receiving filings, and collecting payments. This guide covers the key tax filing dates for 2025, including when tax returns are issued, filing deadlines for individuals and businesses, provisional tax deadlines, how to request an extension, and penalties for late payment. Use our Hong Kong tax calculator to estimate your liability before the deadline.

Key Tax Filing Dates for 2025

The IRD issues individual tax returns each year covering the preceding year of assessment. For the 2024/25 year of assessment, tax returns are typically issued starting in May 2025. The exact issue date varies based on your profile, but you generally have one month from the issue date to file your return. If you need more time, you can apply for a short extension, though the IRD does not grant automatic universal extensions. Keep an eye on your mailbox and the IRD website for the exact issue date.

Salaries Tax Return Deadlines

Salaries tax returns are issued to individuals who obtain income from employment or office. The standard filing deadline is one month from the date of the return. For example, if your BIR60 is issued on June 2, 2025, the due date is July 2, 2025. Late filing attracts a penalty of up to HK$10,000. If you are organized and file early, you can avoid the stress of last-minute submissions and reduce the risk of penalties. Self-assessment is available for straightforward cases.

Profits Tax Return Deadlines

Profits tax returns for businesses are issued based on the company's year-end date. The IRD sets issue dates ranging from early April to late August for different year-end profiles. For example:

• December year-end: Return issued by April 2, file within one month
• March year-end: Return issued by the second Monday of May or later
• Small businesses may receive later issue dates to facilitate compliance

Always check the exact due date on the return itself. For a complete schedule, see our Hong Kong tax deadline calendar overview.

Provisional Tax Deadlines

Provisional tax for both salaries tax and profits tax is typically payable in two installments. The first installment is due in November of the current year, and the second installment is due in April of the following year. The exact dates are shown on the provisional tax demand note. Missing these deadlines results in a 5% surcharge, with an additional 10% surcharge if the tax remains unpaid after six months. Keeping a calendar reminder for these dates helps you manage your cash flow. See our Hong Kong provisional tax guide for strategies to manage provisional payments.

Extension Requests

If you are unable to file by the deadline, you may request a short extension. For individual returns, the IRD considers applications for extension on a case-by-case basis. You can submit an extension request electronically through eTAX or in writing. Provide reasons for the delay, such as missing documents or exceptional circumstances. For business returns, the IRD may automatically allow a longer period if it is justified. However, extensions do not eliminate the surcharge for late payment of provisional tax.

Penalties for Missing Deadlines

Failure to file a tax return on time exposes you to a maximum penalty of HK$10,000. Withholding information or providing false information in a tax return may result in prosecution. Late payment of provisional tax or final tax attracts an initial 5% surcharge on the unpaid amount. After six months, an additional 10% surcharge is imposed. The IRD may also take recovery action, including issuing a warrant to collect the tax. To avoid these consequences, file and pay on time, and use our Hong Kong tax calculator to estimate your liability early.
