Hong Kong’s Salaries Tax regime is comparatively simple when compared with many jurisdictions, but when it comes to married couples, one question that is often asked is:
Shall we go for joint evaluation or individual evaluation? This option can greatly affect your overall tax liability. While both methods are recognized by the Hong Kong Inland Revenue Department (IRD), it depends on your family income and allowances. In this article, we’ll discuss joint vs separate assessment, cover the main differences, and highlight when professional advice—such as that provided by FastLane HR—can guarantee you’re minimizing tax.
What is Joint Assessment in Hong Kong?
Joint filing allows legally married couples to combine their incomes, deductions, and allowances into a single tax return. IRD calculates the total tax payable as if the couple was one taxpayer.
Major characteristics of joint evaluation:
- Both spouses’ income is aggregated.
- Deductions and allowances are combined.
- Typically leads to a reduced total tax burden, particularly if a single spouse earns considerably more than the other.
Where one spouse has a low income, a joint assessment can maximize the unutilized allowances and minimize the total tax payable.
What is Separate Assessment in Hong Kong?
Under separate evaluation, both husband and wife record their tax returns separately. They are taxed based on each of their personal income, deduction and allowance.
Major features of separate evaluation:
- Both husband and wife are independently evaluated as different taxpayers.
- The best works when both have the same income and it can completely use individual allowances and cuts.
- Allows more flexibility in separate cuts.
Example: Where both spouses earn high income and have large deductions (such as charitable gifts or self-education expenses), separate assessment will be more beneficial.
