Tax system in Hong Kong
Hong Kong uses a territorial system. In broad terms, income with a Hong Kong source is within the tax net; worldwide income is not automatically taxed the way it is in many other countries. The Inland Revenue Ordinance, case law, and IRD practice notes (including DIPNs) govern how that principle is applied.
There are three distinct heads of charge. They are assessed separately; mixing them up is a common source of filing errors.
Profits tax
Corporations, partnerships, trustees and bodies of persons carrying on any trade, profession or business in Hong Kong are chargeable to tax on profits arising in or derived from Hong Kong from that activity (capital receipts are treated differently). Source is a question of fact. A Hong Kong company is not automatically taxable on all of its profits, and an overseas company is not automatically outside the net if it carries on business here.
Salaries tax
Imposed on income arising in or derived from Hong Kong from an office, employment or pension. Whether employment income has a Hong Kong source depends on where the employment is located, not only where the employer is incorporated.
Property tax
Levied on owners of real estate in Hong Kong. A corporation that lets Hong Kong property may instead be assessed under profits tax on that income, depending on the facts.
Rates, allowances, two-tier profits tax, and foreign-source income exemption (FSIE) rules change. Confirm the current year with the Inland Revenue Department or your adviser—do not rely on historic published percentages.
The annual filing cycle
Established businesses typically receive profits tax returns around 1 April and must file within the stated period, with accounts and supporting documents. After assessment, the IRD issues a demand note with a payment deadline.
A new company is usually issued its first profits tax return later—often after about 18 months from commencement. That delay is not a reason to skip bookkeeping. Banks, investors, and a later offshore or source analysis all depend on records kept from the first invoice.
Year-end dates of 31 December or 31 March remain common because they align with typical IRD cycles. Choose a date that matches how the business actually reports, then keep to it.
Mistakes we see in SME filings
- Waiting for the first tax return before opening proper books
- Claiming “offshore” treatment without contracts, shipping, or decision-making evidence
- Treating Mainland China VAT/CIT calendars as if they applied to the Hong Kong company
- Ignoring employer’s returns when staff are hired in Hong Kong
- Late replies to IRD letters, which can escalate into estimated assessments
Tax representative service
Appoint us as your tax representative to prepare returns, correspond with the Inland Revenue Department, and coordinate accounts, tax computations, and supporting schedules. We also advise on timing of payments and on when a query is routine versus when it needs a fuller response.
Service scope
Annual tax filing
Profits tax returns, employer’s returns, and related filings, supported by accounts that match the company’s actual operations—not a template that ignores how you trade.
Tax investigation and IRD queries
Sample checks and targeted reviews are part of IRD practice. Careful, documented replies help limit additional assessments, penalties, and disputes. If the group also has a Mainland entity, keep Hong Kong and China correspondence separate—the regimes are different.
Territorial and offshore claims
Where profits do not have a Hong Kong source, they may fall outside profits tax. That is not automatic. The IRD looks at how contracts are concluded, where operations take place, and how the company is managed. We help assemble the fact pattern and filings.
