Relocating Business Operations to Hong Kong: Tax, Accounting and First-Year Reporting Considerations

Introduction: relocation creates a reporting framework

Incorporation or re-domiciliation establishes a legal platform in Hong Kong. A bank account enables the company to receive funding and begin trading. Neither step, however, completes the relocation process. From the first transaction, the company must create an accounting and tax record that can support its financial statements, audit, Profits Tax Return and any position taken on the source of its profits.

For legal and tax professionals, the central point is that a Hong Kong tax position is not created only when a return is filed. It is built throughout the year through contracts, invoices, accounting entries, board decisions and evidence showing where the business was managed and where the profit-producing activities took place.

The first financial year therefore deserves attention at the market-entry stage. Decisions about the form of relocation, accounting period, funding, intercompany arrangements and record-keeping can materially affect the quality of the company’s later reporting.

1. New Hong Kong company or re-domiciliation?

A business can enter Hong Kong through a newly incorporated company, by registering a non-Hong Kong company, or—where the statutory conditions are met—by re-domiciling an existing foreign company to Hong Kong. For this article, the important comparison is between incorporating a new Hong Kong company and re-domiciling the existing entity.

A newly incorporated company starts a separate legal and accounting history. Initial share capital, shareholder or director funding, transferred assets, opening contracts and the first business transactions should be documented as transactions of the new entity.

A re-domiciled company is different. Hong Kong’s company re-domiciliation regime, which commenced in May 2025, allows an eligible non-Hong Kong corporation to become a Hong Kong company while preserving its legal identity and business continuity. Existing contracts, assets and liabilities do not automatically disappear merely because the company changes domicile.

This continuity makes pre-migration review particularly important. The company should identify the accounting values and tax bases of its assets and liabilities, any unrealised profits taxed by the former jurisdiction, existing tax losses, related-party balances and outstanding reporting obligations. Hong Kong’s Inland Revenue Ordinance now contains specific rules for certain re-domiciled companies, including relief intended to address double taxation where equivalent foreign tax was imposed on unrealised income or profits because of the re-domiciliation.

2. Accounting records begin with the first transaction

Hong Kong law requires a business to keep sufficient records of its income and expenditure so that its assessable profits can be readily ascertained. The records generally have to be retained for at least seven years. A failure to maintain adequate records without reasonable excuse may result in a fine.

For a relocating business, the accounting file should normally explain not only what was paid or received, but also why the transaction belongs to the Hong Kong company. This is especially important where operations, personnel, customers or group companies remain in several jurisdictions.

The first-year file should ordinarily include bank statements, sales and purchase invoices, commercial agreements, expense evidence, payroll records, board and shareholder decisions, loan and capital documentation, intercompany agreements, and records showing where services were performed or trading operations were carried out.

Accounting should therefore be established when the business begins, rather than reconstructed shortly before the first audit. A clean opening balance sheet and a properly documented separation between the Hong Kong company and its shareholders or related entities will reduce later difficulties with the auditor, tax adviser, bank and potential investor.

3. Simplified reporting does not usually remove the audit

Foreign investors sometimes assume that a small private company will be exempt from audit. That is generally not the Hong Kong position.

A qualifying private company may fall within the reporting exemption and use a simplified financial reporting framework. This can reduce some financial statement and directors’ report requirements. It is not, however, a general audit exemption. The Companies Registry confirms that financial statements must be audited for companies within the reporting exemption as well as other companies, except companies that are dormant within the meaning of the Companies Ordinance.

The distinction matters when budgeting for relocation. Bookkeeping, preparation of financial statements, audit and tax computation are connected but separate workstreams. Even a modest owner-managed company should plan for them from the outset rather than treating the first audit as an unexpected year-end cost.

Where the Hong Kong company is a holding company, group reporting may also arise. The directors should consider whether consolidated financial statements are required and whether the company qualifies for any permitted reporting relief.

4. The first Profits Tax Return is becoming more document-driven and digital

A corporation carrying on business in Hong Kong will normally need to file a Profits Tax Return when required by the Inland Revenue Department. Current filing requirements place greater emphasis on complete supporting material.

If a corporation has gross income during the basis period, its Profits Tax Return must be submitted with the required supporting documents, including financial statements and a tax computation. The former concession under which small corporations and businesses with gross income not exceeding HK$2 million could file without supporting documents is no longer available.

The filing environment is also increasingly digital. Required supplementary forms have to be filed electronically. All corporations and businesses can use the electronic filing services for eligible years and submit financial statements and tax computations in the prescribed electronic formats. From 1 April 2026, the first phase of mandatory electronic filing applies to relevant entities of in-scope multinational enterprise groups subject to the global minimum tax rules for the year of assessment 2025/26 onwards.

Most newly relocated small and medium-sized companies will not fall within that first mandatory phase. Nevertheless, the direction of travel is clear. Accounting systems and working papers should be capable of producing complete, consistent and electronically usable reporting information.

5. Territorial taxation is a factual analysis, not a slogan

Hong Kong applies a territorial source principle. Broadly, Profits Tax is charged on profits arising in or derived from Hong Kong from a trade, profession or business carried on in Hong Kong. Profits sourced elsewhere are not generally subject to Hong Kong Profits Tax.

This does not mean that income becomes offshore merely because customers, suppliers or shareholders are located outside Hong Kong. The Inland Revenue Department describes the source question as a practical matter of fact. The central enquiry is what the taxpayer did to earn the profits and where those profit-producing operations took place.

For a relocated service business, relevant evidence may include where employees or contractors performed the work, where key decisions were made, where client contracts were negotiated and implemented, and which entity assumed the commercial risks. For a trading business, the analysis may focus on the activities that produced the trading profits and where purchase and sale contracts were effected.

Tax residence and source should also be kept separate. A Hong Kong company may seek a Certificate of Resident Status for treaty purposes, but the certificate does not itself guarantee treaty benefits. Equally, Hong Kong residence does not automatically make all worldwide income taxable. For multinational enterprise entities, specified foreign-sourced income received in Hong Kong may also require a separate review under the foreign-sourced income exemption regime.

The practical lesson is that any offshore claim should be planned as an evidence exercise. The accounting records, contracts and operating facts should support the position taken in the tax computation.

6. Related-party arrangements should be documented early

Relocating a business rarely severs all connections with the existing group, founders or overseas operations. The Hong Kong company may pay or receive management charges, service fees, royalties, interest, cost recharges or other amounts involving associated persons.

These arrangements should be supported by written agreements, a clear description of the functions performed, and commercially supportable pricing. The fact that a payment appears in the accounting records does not by itself establish that it is deductible or priced on an arm’s length basis.

Hong Kong entities may also have to consider master file and local file obligations for controlled transactions, subject to statutory size and transaction thresholds. Where the documentation rules apply, the files generally have to be prepared within nine months after the end of the accounting period and retained for at least seven years.

Even where a company is exempt from formal master file and local file requirements, contemporaneous documentation remains valuable. It explains the commercial basis of cross-border charges and helps maintain consistency between contracts, accounts and tax reporting.

7. A practical first-year reporting framework

A business entering Hong Kong should establish a reporting framework before transaction volumes increase. The framework should identify the chosen accounting year-end, bookkeeping responsibility, document approval process, banking and expense controls, audit timetable, tax filing responsibility, and the treatment of intercompany transactions.

For a newly incorporated company, the opening file should clearly document capital, loans and any transfer of business or assets. For a re-domiciled company, it should also reconcile the pre- and post-re-domiciliation position and preserve records supporting historic values and foreign tax treatment.

The company should also ensure that the legal narrative used for incorporation, bank onboarding and commercial contracting is consistent with the accounting and tax record. A company described to the bank as an active Hong Kong trading business should not later produce accounts and contracts that show an entirely different operating model without a clear explanation.

‍

Relocation to Hong Kong is not complete when the company is incorporated or the bank account is opened. The business must be able to record, audit and report its activities in a form that is consistent with Hong Kong company and tax law.

The first year is particularly important. It establishes the company’s opening balances, accounting discipline, audit process, tax filing history and evidence for any territorial-source position. Where the existing entity is re-domiciled, the transition also requires careful review of historic assets, liabilities and foreign tax consequences.

For investors, business owners and professional advisers, early accounting and tax planning is therefore part of the relocation itself. A company that builds a reliable record from the first transaction is better prepared for audit, tax filing, bank review and future commercial due diligence.

Frequently asked questions

# Must accounting records be kept before the first tax return is issued?

Yes. Records should be created from the first transaction. Reconstructing the accounting file only before audit increases the risk of inconsistencies, unsupported expenses and a weak source-of-profits position.

# How long must Hong Kong business records be retained?

Sufficient accounting and business records generally have to be retained for at least seven years.

# Is statutory audit required for a small private company?

Generally, yes. Reporting exemption is not a general audit exemption; the principal exception concerns dormant companies.

# When does mandatory electronic filing of Profits Tax Returns apply?

The first mandatory phase applies from 1 April 2026 to relevant entities of in-scope multinational enterprise groups under the global minimum tax rules, beginning with the year of assessment 2025/26.

# Can an offshore profits claim be based only on foreign customers?

No. The company must identify the profit-producing operations and show where they were carried out.

# Does a Certificate of Resident Status guarantee treaty benefits?

No. It supports an application for treaty benefits, but entitlement depends on the relevant treaty, the facts and applicable anti-abuse rules.

# When are master file and local file documents prepared?

Where the statutory requirements apply, the files generally have to be prepared within nine months after the end of the relevant accounting period and retained for at least seven years.

# What should be included in the opening file of a re-domiciled company?

The file should normally include a migration-date balance sheet, bank and intercompany reconciliations, asset registers, tax bases, foreign tax evidence, capital and loan records, and outstanding reporting obligations.
