Self-Employed Tax in Hong Kong Confirm the cited source.

Hong Kong taxes self-employed individuals through the Inland Revenue Ordinance (Cap 112), administered by the Inland Revenue Department (IRD). Sole proprietors pay Profits Tax on assessable profits, register their business within one month of commencing trade, and contribute to the Mandatory Provident Fund (MPF). There is no personal income tax on business profits separate from Profits Tax, no VAT or GST, and no capital gains tax -- making Hong Kong's framework among the most straightforward for self-employed persons globally.

01How does Hong Kong's two-tiered Profits Tax work for sole proprietors?

The two-tiered Profits Tax regime, effective from the year of assessment 2018/19, applies reduced rates for smaller unincorporated businesses. A sole proprietor with HKD 1.5 million in assessable profits pays HKD 112,500 (7.5% flat). A sole proprietor with HKD 2.5 million pays HKD 225,000: HKD 150,000 on the first HKD 2 million at 7.5%, plus HKD 75,000 on the remaining HKD 500,000 at 15%. Only one connected entity within a group may elect the two-tiered rates in any given year of assessment; elections are irrevocable for that year.

02What is the territorial-source principle and how does it affect taxable profits?

Hong Kong taxes only profits that arise in or are derived from Hong Kong. Profits sourced outside Hong Kong are not subject to Profits Tax, regardless of the taxpayer's residence. The IRD applies an operations test: assessors examine what the taxpayer did to earn the profits and where those activities took place. For service businesses, the decisive factor is where services were performed. For trading businesses, source follows where purchase and sale contracts were negotiated, concluded, and executed. Offshore profits must be supported by documented evidence of substantive activity outside Hong Kong; the IRD provides advance rulings for taxpayers seeking certainty on source determinations.

03Which deductions and depreciation allowances reduce assessable profits?

Under Inland Revenue Ordinance Section 16, all outgoings and expenses incurred wholly and exclusively in producing chargeable profits are deductible. Common allowable items include rent, staff salaries (but not the proprietor's own drawings), business insurance, and professional fees. Importantly, accounting depreciation is not deductible -- only statutory depreciation allowances prescribed by the IRD apply. For plant and machinery, a 60% initial allowance applies in the year of purchase, followed by annual allowances at 10%, 20%, or 30% on the reducing pool value depending on the asset class. For commercial buildings, a 4% annual allowance applies with no initial allowance; industrial buildings receive a 20% initial allowance plus 4% annually. Mandatory MPF contributions (up to HKD 18,000 per year) are deductible under Section 16AA. [Source: IRD Profits Tax (Businesses)][3]

04What is Provisional Profits Tax and how is it collected?

Because final assessable profits for a year cannot be determined until after the accounting year ends, the IRD raises a Provisional Profits Tax charge based on the prior year's assessed profits. The provisional amount and the final tax for the prior year are typically collected together in two instalments -- the first covering approximately 75% of the combined amount, the second covering 25%, spaced about three months apart. Once final profits for the current year are assessed, the provisional tax paid is set off against the actual liability. A self-employed person whose income has dropped significantly may apply to have Provisional Profits Tax reduced. For the year of assessment 2025/26, the 2025-26 Budget introduced a one-off 100% reduction of final Profits Tax, subject to a ceiling of HKD 3,000 per case, applied automatically on assessment -- no separate application is required.

05What return does a sole proprietor file, and when?

A sole proprietor who owned the business solely throughout the year reports profits or losses in Part 5 of the Tax Return -- Individuals (BIR60), which the IRD issues annually. Where a business was held jointly with others, or changed structure during the year, the Profits Tax Return (BIR52) is used instead. The extended paper filing deadline for sole proprietors for the 2025/26 year of assessment is 4 August 2026; an additional one-month extension is granted automatically for electronic filing via IRD's eTAX portal. For businesses with annual gross income not exceeding HKD 2 million, certified financial statements do not need to be submitted with the return, but must be retained and available on request. Records must be kept for seven years under Inland Revenue Ordinance Section 51C. [Source: IRD Tax Reporting for Profits Tax -- Sole Proprietorship and Partnership][4]

06What are the MPF obligations for self-employed persons?

Self-employed persons (SEPs) are required to enrol in a registered MPF scheme and make mandatory contributions of 5% of relevant income. Contributions are required only when monthly relevant income is at or above HKD 7,100 (the current minimum relevant income level). The maximum relevant income level is HKD 30,000 per month, so the maximum mandatory contribution is HKD 1,500 per month (HKD 18,000 per year). SEPs may choose to contribute monthly or annually; annual contributions are due by the last day of the scheme's financial year. A SEP who suffers a net business loss in a year may declare the loss and suspend contributions until income again reaches the minimum threshold. Mandatory MPF contributions are fully deductible against Profits Tax assessable profits. [Source: MPFA -- Self-Employed Persons][5]

07What does Business Registration require for a sole proprietor?

Every person carrying on business in Hong Kong must register under the Business Registration Ordinance (Cap 310). A sole proprietor must apply within one month of commencing business by submitting Form 1(a) together with a copy of their Hong Kong identity card (or passport for non-residents) to the IRD Business Registration Office. Applications can be submitted in person at the Inland Revenue Centre in Kai Tak, by mail, or online via eTAX for sole proprietorships. From 1 April 2026, a one-year Business Registration Certificate costs HKD 2,200 plus a HKD 150 levy, totalling HKD 2,350; a three-year certificate costs HKD 5,720 plus a HKD 450 levy, totalling HKD 6,170. Failure to register on time is a criminal offence carrying a fine of up to HKD 5,000 and up to one year's imprisonment. [Source: IRD -- Business Required to be Registered][6]
