What’s the Difference Between Fiscal Year and Year-End Date?
For limited companies incorporated in Hong Kong, submitting annual tax returns accurately and on time is essential. Understanding the company tax submission timeline and requirements helps ensure compliance and avoids penalties for late or incorrect filings. This guide by NOVA explores tax filing deadlines, key requirements, and important considerations for Hong Kong limited companies.
New Company Tax Filing Timeline
The Inland Revenue Department typically issues the first new company tax return about 18 months after incorporation. For new company tax filings, the deadline is 3 months from receiving the tax return. Note that extensions are not permitted for first-time filings.
Limited Company Tax Submission Deadlines
The Inland Revenue Department usually issues annual tax returns on the first working day of April. Companies must submit their company tax submission within 1 month of receiving the return. The exact deadline is printed on the first page of the tax return.
Extensions for Profit Tax Returns
Companies with tax representatives may apply for extensions based on their fiscal year-end:
- Code N (April 1, 2024 –November 30, 2024): No extension
- Code D (December 1, 2024–December 31, 2024): Extended to August 15, 2025
- Code M (January 1, 2025–March 31, 2025): Extended to November 17, 2025
- Code M Loss-making companies: Extended to February 2, 2026
Unlimited Company Tax Submission Deadlines
Unlimited companies (partnerships/sole proprietorships) follow slightly different company tax submission rules and do not require audited reports.
Partnership Tax Filing
Tax returns are issued on the first working day of April. Partnerships must file Form BIR52 within 1 month but may apply for extensions under the same rules as limited companies.
Sole Proprietorship Tax Filing
Returns are issued on the first working day of May. Sole proprietors must complete Part 5 of Form BIR60 (individual tax return) within 1 month. Extensions are generally not allowed unless under exceptional circumstances.
