- Supporting Documents: Retain your bank interest statements, loan agreements, mortgage documents, and proof of address.

Business Expense Deductions: Section 16 Principles of the Inland Revenue Ordinance
For businesses, Section 16(1) of the Inland Revenue Ordinance establishes the basic principle: "All outgoings and expenses incurred in the production of assessable profits shall be deducted." However, this broad principle is subject to specific conditions and exclusions.
Generally Deductible Business Expenses
| Expense Category | Tax Deduction Considerations |
|---|---|
| Rent and Rates | Fully deductible for business premises; mixed use must be apportioned pro rata |
| Salaries and Wages | Employees' salaries are deductible; proprietor's/partners' drawings or salaries are not deductible |
| Interest Expenses | Deductible if the borrowed money is used for the purpose of producing assessable profits |
| Repairs and Maintenance | Revenue repairs are deductible; capital improvements are not deductible (depreciation allowances should be claimed instead) |
| Professional Fees | Accounting, legal, and consultancy fees related to business operations |
| Bad Debts | Deductible if proved to be irrecoverable and previously included in assessable profits |
Non-Deductible Expenses: Section 17 Exclusions under the Inland Revenue Ordinance
- Domestic or Private Expenses: Personal living expenses, household expenses.
- Capital Expenditure: Asset acquisition costs, capital improvements (depreciation allowances should be claimed instead).
- Taxes under the Inland Revenue Ordinance: Profits Tax, Property Tax, Salaries Tax (except Salaries Tax paid on behalf of employees).
- Drawings by Proprietor/Partners: Salaries and interest on capital paid to business owners.
- Non-Approved Donations: Donations made to charitable institutions not recognized by the Inland Revenue Department.
- Fines and Penalties: Regulatory fines, traffic penalties.
Complex Tax Deduction Scenarios: Practical Solutions
Scenario 1: Mixed-Use Business and Residential Property
Situation: A sole proprietor operates a business from a property where 60% is used for business and 40% for personal residence.
Solutions:
- Apportion expenses (rent, utilities, repair costs) based on the actual percentage of business use (60%).
- Deduct 60% of mortgage interest under Profits Tax, or claim the full home loan interest deduction under Salaries Tax—but not both.
- Retain clear supporting documentation: floor plans, time logs, expense receipts.
- Calculate which method yields greater overall tax savings.
Scenario 2: Excess MPF Contributions Due to Multiple Employers
Situation: An individual works for three employers, with mandatory MPF contributions totaling HK$25,000 per year across all employers.
Solution:
- Claim a tax deduction of only HK$18,000 on your tax return (the statutory cap).
- Apply to the MPFA for a refund of excess contributions exceeding the annual cap.
- Retain records from all employers showing the contribution amounts.
- Use the pre-filled MPF information in the "eTAX" system to cross-check for accuracy.
Scenario 3: Pursuing Studies for a Career Change
Situation: A marketing professional enrolls in a Master of Science in Data Science program to transition careers.
Solution:
- Tax deductibility depends on whether the course is undertaken to maintain or improve skills required in the current employment.
- Acquiring completely new skills for a different profession may not be tax-deductible.
- If the current employer requires data science skills, or if marketing roles increasingly demand such knowledge, the case for claiming a deduction is stronger.
- Document employer support, evolving job descriptions, or written confirmation that the course is job-related.
Documentation and Compliance: Avoiding Common Pitfalls
Essential Supporting Documents for Tax Deduction Claims
| Deduction Category | Required Supporting Documents |
|---|---|
| Home Loan Interest | Bank interest statements, loan agreements, mortgage documents, proof of residential address |
| Domestic Rent | Tenancy agreement, rent receipts, landlord's particulars |
| MPF Contributions | MPF contribution statements issued by trustees, employer records |
| Self-Education Expenses | Course enrollment confirmation, tuition fee receipts, course syllabus |
| Approved Charitable Donations | Official donation receipts issued by recognized charitable institutions (Section 88 format) |
