Understanding Hong Kong Tax Audit Triggers: What Catches the IRD's Attention?

The Hong Kong Inland Revenue Department uses a sophisticated risk-based approach to select businesses for audit. Understanding these triggers is not about finding loopholes, but about identifying and addressing potential issues before they escalate into audit concerns.

• Unexplained Fluctuations in Profits: Sudden drops in reported profits, or sharp increases in expenses without clear commercial justification.
• Persistent Losses: Companies reporting losses year after year, especially when industry peers are generally profitable.
• Inconsistent Reporting: Discrepancies across different financial reports, or inconsistent tax filing practices.
• Related-Party Transactions: Connected transactions that do not adhere to the arm's length principle.

2. Segregation of Duties: Assign bookkeeping, authorization, and asset custody functions to different personnel.
3. Regular Reconciliations: Perform monthly bank reconciliations and conduct periodic reviews of accounts.
4. Documentation Standards: Formulate consistent supporting documentation requirements across all departments.
