Deloitte called on the Hong Kong government to offer tax breaks and incentives to Chinese e-commerce firms based in the city but are operating globally, The Standard reported Wednesday.

Should the e-commerce firms declare their income, Hong Kong could treat half of their profits as offshore income and could be tax-exempt, the report said, citing Deloitte's pre-budget proposals.

The proposal should help eliminate uncertainty over taxes while boosting Hong Kong's revenue, the report said.

Deloitte also called on Hong Kong to introduce a preferential 8.25% tax rate for international commodity traders based in the city, the report said.
