Every year from April 1st to April 30th is the designated time for filing China's Hong Kong Salaries Tax, a key focus for both businesses and individuals working in Hong Kong. Especially for Mainland Chinese residents working in Hong Kong, core issues such as combined tax filing, the latest allowances, and the Hong Kong Tax Resident Certificate are directly related to tax compliance and rights. This article explains the key points to help you understand and avoid risks.
This article, combining the official regulations of the Hong Kong Inland Revenue Department and Mainland tax authorities, focuses on core information, simplifies redundant content, and highlights the key compliance points and rights of interest to Mainland residents.
Hong Kong Salaries Tax follows the "territorial source principle of taxation." Employment income derived from Hong Kong must be declared. This is particularly relevant for Mainland residents: regardless of whether they are Hong Kong permanent residents, anyone working in Hong Kong and earning income from Hong Kong sources must file Hong Kong Salaries Tax. Simultaneously, they must also fulfill their obligation to file a consolidated individual income tax return in the Mainland. This is a key focus for Mainland residents filing taxes in Hong Kong.
Hong Kong’s latest allowances for the 2025/26 and 2026/27 tax years (official update) that Mainland residents in Hong Kong can directly apply (unit: HKD) to reasonably enjoy tax benefits:
Type of Allowance | 2025/26 Tax Year (Current) | 2026/27 Tax Year and After |
Basic Allowance | 132,000 | 145,000 |

Supporting Parent/Grandparent aged 55-59 (per person) | 25,000 | 27,500 |
Elderly Residential Care Expenses Deduction Limit | 100,000 | 110,000 |
Essential Knowledge on Combined Tax Filing for Mainland Residents
Beyond understanding the latest allowances, there is a crucial compliance requirement for Mainland residents that cannot be ignored: Combined Tax Filing. As Mainland tax residents, we need to declare our Hong Kong-sourced salaries income and Mainland income together for individual income tax purposes. This helps avoid double taxation and prevents underreporting violations. The key points are as follows:
1. Core Principle: Fulfill the "worldwide taxation" obligation; Hong Kong salaries tax already paid can be credited against Mainland tax liability upon presentation of a tax payment certificate.
2. Important Reminder: Combined filing has specific deadlines, document requirements, and operational standards; avoid procedural errors that could lead to penalties.
3. Noteworthy: The combined filing process is complex with stringent documentation requirements; even minor omissions or errors could result in compliance penalties!
After understanding the allowances and combined filing, another benefit that can significantly enhance your tax position is worth noting: the Hong Kong Tax Resident Certificate. It is not optional; for Mainland residents, having this certificate unlocks multiple core advantages, substantially reducing tax costs and safeguarding personal rights. Specific advantages include:
Tax Benefits: Eligibility for the "Arrangement between the Mainland of China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation," preventing dual taxation in both Hong Kong and the Mainland, thereby reasonably lowering overall tax burden.
Rights Protection: Serves as a core credential for enjoying Hong Kong tax exemptions and Mainland tax credits, ensuring tax filing compliance and avoiding audit risks.
Convenience: Simplifies cross-border tax filing procedures, making subsequent tax-related matters in both Hong Kong and the Mainland more efficient and less cumbersome.
Long-term Value: Facilitates personal cross-border tax planning, providing compliance safeguards for future work and life in Hong Kong.
Given the many advantages of the Hong Kong Tax Resident Status, many wonder how to apply. However, its application has specific eligibility criteria, and the document preparation process is relatively complex. Missing details in the process can delay handling or even affect benefit eligibility.
Warm Reminder
Overall, compliance in filing is a core obligation for both enterprises and individuals. The specifics of the combined filing process and the Hong Kong Tax Resident Certificate application, which are of particular concern to Mainland residents, are highly specialized. Professional guidance is recommended to avoid pitfalls and handle matters efficiently.
