How Hong Kong profits tax works

24 May 2026 · 7 min read

Territorial source, two-tiered rates and deductibility: the mechanics behind the headline rate, and where offshore claims succeed.

Hong Kong taxes profits arising in or derived from Hong Kong from a trade, profession or business carried on here. Residence is not the test; source is. That single principle explains almost everything that feels unusual about the system to companies arriving from worldwide-taxation jurisdictions.

The territorial principle

Three conditions must be met for a profit to be chargeable: there is a trade, profession or business carried on in Hong Kong; the profit arises from that activity; and the profit arises in or is derived from Hong Kong. A company can be incorporated here, banked here and administered here, and still have profits sourced elsewhere; the reverse is equally possible.

Source is determined by the operations test: what the taxpayer did to earn the profit, and where those operations took place. The courts have consistently looked at the effective causes of the profit rather than at contract law formalities or the location of customers alone.

Rates and the two-tiered regime

Corporations are taxed on a two-tiered basis: a lower rate on the first tranche of assessable profits and the standard rate above it. Unincorporated businesses have their own equivalent pair of rates.

The lower tier is available to only one entity within a group of connected entities, and the group must nominate which one claims it each year. Splitting a business across several companies to multiply the benefit does not work, and the connected-entity definition is deliberately broad.

Deductibility

The general test is that outgoings and expenses are deductible to the extent they are incurred in the production of chargeable profits. Capital expenditure is not deductible, nor are domestic or private expenses, general provisions, or expenditure incurred in producing non-chargeable profits.

Depreciation allowances substitute for accounting depreciation on qualifying assets, with immediate write-off available for prescribed fixed assets such as computer hardware and certain manufacturing plant. Specific regimes cover intellectual property rights, environmental protection facilities and building refurbishment.

Interest deductibility has its own conditions and is where intra-group financing arrangements most often fail. Test the structure before the loan is drawn, not at the audit.

Offshore claims

An offshore claim asserts that profits, though earned by a Hong Kong company, arose outside Hong Kong. Claims succeed on evidence about operations: where the contracts were negotiated and concluded, where the services were performed, who performed them, where the goods were sourced and shipped, and where the decisions were made.

Documentation created at the time carries far more weight than a narrative written years later. Travel records, meeting notes, correspondence showing negotiation, signed contracts with dates and places, and staff location records are the substance of a claim. Expect an enquiry, and expect it to focus on the years already filed rather than on the year in question alone.

A successful claim is not permanent. It reflects a pattern of operations, and if the operating model changes (a local hire, a decision moved to Hong Kong, a new customer base) the position has to be reassessed.

What Hong Kong does not tax

There is no value added tax, no sales tax, no capital gains tax, and no withholding tax on dividends or interest paid to non-residents. Dividends received are not chargeable, which is why holding structures sit here comfortably.

The exception to remember is royalties: sums paid to a non-resident for the use of intellectual property in Hong Kong are chargeable, collected from the payer. Payments to non-resident entertainers and sportspersons are treated similarly.

Foreign-sourced income and substance

Hong Kong has introduced a foreign-sourced income exemption regime for certain passive income (dividends, interest, disposal gains and IP income) received by multinational entity groups, with economic substance, nexus and participation requirements attached. Groups relying on non-taxation of offshore passive income should test their position against those requirements rather than assume the historic outcome still applies.

We prepare the computation, advise on the source position before it hardens, and handle offshore claims and the enquiries that follow them.
