Complete Guide to HK Tax System for Clinic Owners

Profits Tax: The Primary Tax for Clinic Businesses

Profits tax is levied on assessable profits arising in or derived from Hong Kong from a trade, profession, or business. For incorporated clinics, the two-tier system applies: the first HK$2 million of assessable profits is taxed at 8.25%, with profits above that taxed at 16.5%. For unincorporated practices, the rates are 7.5% and 15% respectively. Allowable deductions include staff costs, rent, professional fees, equipment depreciation, and specific medical supplies, but the rules around what qualifies are precise and require careful record-keeping.

Salaries Tax and IR56 Obligations

Clinic operators who employ staff are required to report employee remuneration to the Inland Revenue Department via IR56 forms. IR56B is filed annually for each employee, IR56E is filed when a new employee joins, IR56F when an employee leaves, and IR56G for employees departing Hong Kong permanently. Clinics that engage locum doctors on a self-employed basis face an additional obligation: IR56M, which must be filed by 31 August each year to report fees paid to self-employed contractors during the preceding assessment year. Failure to file any of these forms on time attracts IRD penalties. For clinics with part-time or locum staff — common in the sector — correctly determining employment vs. self-employment status determines which IR56 forms apply; getting this wrong creates compliance exposure in both directions.

Tax Compliance Planning Strategies for Clinics

Several lawful approaches can help clinics manage their tax position effectively without aggressive or complex structures:

• Maximise allowable deductions: Ensure all qualifying expenses, including professional development, insurance, and equipment, are properly claimed
• Timing of capital expenditure: Purchasing equipment before year-end can accelerate depreciation allowances
• Two-tier profits tax: Structure the business to benefit from the lower first-tier rate where possible
• Spouse and family employment: Where genuine employment exists, salaries paid to family members may be deductible
• MPF contributions: Employer MPF contributions are deductible up to statutory limits
• Tax reserve certificates: Purchasing IRD tax reserve certificates before assessment can reduce interest exposure

Common Mistakes That Cost Clinic Owners Money

The most frequent tax mistakes BM sees in clinic accounts:

• Missing the profits tax return filing deadline (typically within 1 month of issue; extension requests must be made proactively)
• Claiming personal expenses through the business without proper substantiation
• Incorrectly treating capital expenditure as revenue expenditure (or vice versa)
• Failing to track medical supply costs separately from operational expenses
• Not maintaining adequate records to support deduction claims. IRD can query up to 6 years back
• Missing IR56 filing deadlines for staff changes during the year
