Hong Kong self-employed tax calculator (sole proprietor)

How sole proprietor in Hong Kong is calculated

An unincorporated business pays **profits tax at two tiers**: 7.5% on the first $2 million of assessable profits and 15% on the rest. There are no personal allowances under profits tax, so on $462,000 of assessable profits the bill is $34,650.

**Personal assessment can undercut it.** An individual ordinarily resident in Hong Kong may elect to have business profits taxed at the salaries-tax progressive rates (2%, 6%, 10%, 14% on $50,000 bands, then 17%) after the personal allowances — from 2026/27 a $145,000 basic allowance, $290,000 for a married person whose spouse has no income, and $140,000 per child. On $300,000 of profit that is $8,000 instead of $21,375. The calculator works out both and takes the lower.

**Your own MPF comes first.** A self-employed person contributes 5% of relevant income between $85,200 and $360,000 a year — nothing below, $18,000 at most — and the contribution is deductible from assessable profits up to $18,000.

Only one business in a group of connected entities may use the lower 7.5% tier; the page assumes yours does. Losses, depreciation allowances and the rules on what expenses are deductible sit upstream of the profit figure you enter. Estimate, not tax advice.
