Introduction to Hong Kong Profits Tax

Hong Kong operates a territorial tax system, which means only profits arising in or derived from Hong Kong are subject to profits tax. This principle makes Hong Kong one of the most attractive jurisdictions for international business.

Unlike many other jurisdictions, Hong Kong does not impose tax on worldwide income. If your business generates profits from activities conducted entirely outside Hong Kong, those profits are generally not taxable in Hong Kong.

Who is Subject to Profits Tax?

Profits tax is charged on every person (including corporations, partnerships, trustees, and bodies of persons) carrying on a trade, profession, or business in Hong Kong in respect of their assessable profits arising in or derived from Hong Kong.

Key Points

  • Corporations: All limited companies incorporated in Hong Kong or carrying on business in Hong Kong
  • Unincorporated businesses: Sole proprietors and partnerships operating in Hong Kong
  • Non-residents: Foreign companies with profits sourced from Hong Kong

Two-Tiered Tax Rates

Since the year of assessment 2018/19, Hong Kong has implemented a two-tiered profits tax rates regime to reduce the tax burden on enterprises.

For Corporations (Limited Companies)

ProfitsTax Rate
First HK$2,000,0008.25%
Remainder16.5%

For Unincorporated Businesses

ProfitsTax Rate
First HK$2,000,0007.5%
Remainder15%

Important Restrictions

Only one entity within a group of connected entities can elect to benefit from the two-tiered rates. Connected entities must nominate which entity will enjoy the reduced rate.

Calculating Assessable Profits

Assessable profits are calculated by taking your gross income and deducting allowable expenses. The basic formula is:

Assessable Profits = Gross Income - Allowable Deductions

Allowable Deductions

The following expenses are generally deductible:

  • Rent for business premises
  • Employee salaries and benefits
  • Depreciation allowances on plant and machinery
  • Bad debts (written off)
  • Interest on business loans
  • Repairs and maintenance
  • Professional fees related to business operations

Non-Deductible Items

Certain expenses cannot be deducted:

  • Private or domestic expenses
  • Capital expenditure (except depreciation allowances)
  • Tax payments
  • Expenses not incurred in producing assessable profits

Filing Requirements

Profits Tax Return

The Inland Revenue Department (IRD) issues Profits Tax Returns annually, typically in April. The filing deadline depends on your accounting year-end date:

Accounting Year-EndFiling Deadline
1 April - 30 NovemberWithin 1 month of issue
1 December - 31 DecemberMid-August
1 January - 31 MarchMid-November

Required Documents

When filing your Profits Tax Return, you must submit:

  1. Completed tax return form (BIR51 for corporations, BIR52 for unincorporated businesses)
  2. Audited financial statements (for corporations)
  3. Tax computation
  4. Supporting schedules

Provisional Profits Tax

The IRD levies provisional profits tax based on the previous year's assessable profits. This is payable in advance and will be credited against the final tax liability.

Objection to Provisional Tax

You may apply to hold over provisional tax if you expect your current year profits to be substantially lower than the previous year.

Source of Profits

Determining the source of profits is crucial in Hong Kong's territorial tax system. The IRD applies the "operations test" to determine where profits arise.

Key Factors

  • Where contracts are negotiated and concluded
  • Where goods are manufactured or services performed
  • Where business decisions are made
  • Where customers are located

Penalties for Non-Compliance

Failure to comply with profits tax obligations can result in:

  • Late filing: Penalty up to HK$10,000 and additional tax of up to 3 times the tax undercharged
  • Incorrect returns: Penalty up to HK$50,000 and additional tax of up to 3 times the tax undercharged
  • Failure to keep records: Fine up to HK$100,000

Record Keeping Requirements

Businesses must maintain sufficient records to enable assessable profits to be readily ascertained. Records should be kept for at least 7 years.

Required Records

  • Sales and purchase invoices
  • Bank statements
  • Receipts and payment vouchers
  • Contracts and agreements
  • Payroll records

Conclusion

Understanding Hong Kong's profits tax system is essential for business compliance and tax planning. The territorial basis of taxation and two-tiered rates regime offer significant advantages, but proper record-keeping and timely filing are crucial to avoid penalties.

For complex tax situations or specific advice, consider consulting a qualified tax professional or your company secretary.
