For both limited and unlimited companies in Hong Kong, tax filing is a crucial annual legal obligation. The complex tax regulations and tedious filing processes often pose challenges for businesses. This NOVA guide explains everything about limited company tax and unlimited company tax, including tax exemptions and key considerations, helping you master essential tax filing details while focusing on business growth.
Tax Filing Guide & Required Documents for Limited & Unlimited Companies
We’ve prepared a comprehensive tax filing guide covering tax liabilities, declaration forms, and applicable exemptions for both limited company tax and unlimited company tax. Below, we explain the basic processes, important documents, and key considerations.
Limited Company Tax: Filing Process & Required Documents
In Hong Kong, limited companies typically begin receiving their Profits Tax Return (BIR51) on the first working day of April each year. For newly incorporated companies, the first tax return will be issued approximately 18 months after establishment.
Key limited company tax updates effective April 1, 2023:
- All Hong Kong-registered limited companies must now submit audited financial statements (Audit Report) and supporting documents with their Profits Tax Return
- This requirement applies regardless of:
- Annual revenue (even if below HK$2 million)
- Whether the company conducted any transactions
- Whether the company maintained a bank account
- Only inactive companies are exempt
- Companies must engage professional accountants annually to conduct audits and submit returns
For limited company tax purposes, required documents include audited financial statements (prepared by either in-house auditors or third-party audit firms) and supporting documentation as proof of profits tax declarations. This new regulation means all active limited companies must now fulfill audit and filing obligations, regardless of their revenue status or operational activity. Required Documents for Limited Company Tax:
- Profits Tax Return (BIR51)
- Audited financial statements
- Profits Tax computation sheet
Unlimited Company Tax: Filing Process & Required Documents
Unlike limited companies, unlimited company tax filings are simpler, as they don’t require audited reports. However, proper bookkeeping of income and expenses is mandatory.
Sole Proprietorships vs Partnerships:
- Sole proprietorships report profits directly in the individual tax return (BIR60, Part 5 – Profits Tax), issued on the first working day of May.
- Partnerships receive the Profits Tax Return (BIR52) on the first working day of April, detailing profit allocations to each partner.
Required Documents for Unlimited Company Tax:
- Individual Tax Return (BIR60 for sole proprietorships) or Profits Tax Return (BIR52 for partnerships)
- Profit & Loss Statement and Balance Sheet (if annual income exceeds HK$2 million)
Tax Exemptions & Deductions for Limited & Unlimited Companies
While Hong Kong does not offer standard tax exemptions like personal salaries tax, businesses can reduce taxable profits through deductions, including:
- Operational expenses (rent, salaries, interest, etc.)
- Depreciation of qualifying fixed assets
- Donations to approved charities
- Eligible R&D expenditures
- Eco-friendly equipment costs
Two-Tiered Tax Rates:
- Limited company tax: 8.25% on first HK$2M profits; 16.5% thereafter
- Unlimited company tax: 7.5% on first HK$2M profits; 15% thereafter
Proper record-keeping and leveraging deductions can significantly lower tax liabilities.
The tax filing process for Hong Kong companies is complex and time-consuming, often involving intricate documentation and tax regulations.
