Singapore Holding and Trading Companies: A Guide for Vietnamese Businesses

Singapore can support Vietnamese manufacturers and business owners with regional sales, overseas investment, and succession planning. The benefits depend on the structure’s commercial purpose, the activities performed in Singapore, and compliance with Vietnamese outward-investment requirements.

For a Vietnamese manufacturer expanding overseas, the next stage of growth may involve more than finding export customers. The business may need to manage regional distributors, negotiate international contracts, raise capital, acquire another company, or establish how ownership will pass to the next generation.

Assess the ownership, tax, and regulatory requirements for establishing a Singapore platform to support your overseas growth.

Singapore can provide a base for selected commercial and ownership functions while production remains in Vietnam. A trading company can coordinate overseas sales, a holding company can own regional investments, and an ownership arrangement can support continuity in a family business.

These structures serve different purposes. Their value depends on matching ownership, decision-making, personnel, and financial flows to the business’s actual operations.

What can a Singapore structure do?

A Vietnamese company can establish a Singapore subsidiary to support overseas operations. A Singapore parent company may instead hold interests in regional subsidiaries, potentially including a Vietnamese business, where the investment and restructuring requirements are satisfied.

The ownership direction affects how capital is transferred, profits are distributed, and transactions are regulated.

A business may combine functions in one company or use separate entities where scale, risk, or investor requirements justify the additional cost.

Establishing a Singapore company does not automatically place it above an existing Vietnamese business. A restructuring may require share transfers or exchanges, valuation, tax analysis, investment procedures, and assessment of foreign ownership conditions.

Vietnam’s outward-investment framework expressly addresses cross-border share swaps. Relevant transactions require outward-investment procedures before the swap, market-based valuation, and compliance with applicable Vietnamese inward-investment requirements where a foreign investor acquires interests in a Vietnamese business.

How can a Singapore trading company support Vietnamese exporters?

An illustrative arrangement involves a Vietnamese manufacturer selling goods to a related Singapore trading company, which resells them to an independent overseas customer. The goods may be shipped directly from Vietnam to the customer, while the Singapore business performs defined commercial functions.

Review transfer pricing, tax residence, and outward-investment obligations across your Vietnam and Singapore businesses.

Those functions could include developing customers, negotiating contracts, managing distributors, arranging working capital, or controlling credit and inventory risks. Centralising selected activities may help a manufacturer coordinate sales across several markets and build a regional commercial team.

The appropriate model depends on who makes decisions and bears risk. A sales agent, a distributor with limited responsibilities, and a trading principal that controls substantial commercial risks would not necessarily earn the same return.

Can the Singapore company retain a trading margin?

A Singapore company can earn a commercially justified return for its activities. Related-party prices must, however, be consistent with the arm’s length principle.

The Inland Revenue Authority of Singapore (IRAS) links profit allocation to economic activity and value creation. Issuing an invoice from Singapore is therefore insufficient on its own to justify allocating the associated profit there.

Businesses should identify who negotiates prices, approves customer credit, funds transactions, manages claims, and controls relevant risks. Contracts should reflect actual conduct, with supporting records and transfer pricing documentation where required.

Vietnam’s rules must be assessed alongside Singapore’s. Vietnam’s Decree No. 255/2026/ND-CP, effective from 1 July 2026, governs tax administration of related-party transactions. It replaces Decree No. 132/2020/ND-CP and Decree No. 20/2025/ND-CP and applies from the 2026 corporate income tax period.

The operating model should also align with customs documentation, shipping arrangements, insurance, and customer contracts. Routing an invoice through Singapore does not itself change the goods’ origin.

Where goods are delivered directly from Vietnam to another destination outside Singapore without entering Singapore, the Singapore company’s sale is generally outside the scope of Singapore goods and services tax (GST). This differs from a zero-rated export of goods from Singapore.

Can overseas profits be retained in Singapore?

Businesses should distinguish between allocating profit, paying tax, and retaining funds overseas.

First, the profit attributed to the Singapore entity must reflect its activities. Second, its tax treatment depends on the character and source of the income and any applicable relief. Third, the Vietnamese investor must assess whether retaining or reinvesting funds complies with Vietnam’s outward-investment and foreign-exchange requirements.

Singapore’s standard corporate income tax rate is 17 percent. Income from overseas customers is not automatically tax-exempt. If that income comes from business activities carried on in Singapore, it may be taxable when earned, even if payment is received and kept in a bank account outside Singapore. Holding the money overseas does not, by itself, make the income tax-exempt.

Vietnam’s reinvestment and repatriation requirements

Under Decree No. 103/2026/ND-CP, overseas investment profits may be retained for specified reinvestment purposes: completing registered capital contributions, increasing outward investment capital, or undertaking a new overseas investment project. Applicable investment procedures must be completed.

Except where profits are retained for permitted reinvestment, investors must generally remit overseas investment profits and other income to Vietnam within 12 months of profit distribution. An extension of up to a further 12 months requires advance written notification to the Ministry of Finance and the State Bank of Vietnam.

The distribution trigger matters: the deadline should not be presented as running automatically from the date the Singapore company earns its profit. Equally, leaving profits undistributed should not be assumed to remove Vietnamese compliance obligations.

Investors must also follow Circular No. 34/2026/TT-NHNN, effective from 31 July 2026, on foreign-exchange management for outward investment. This includes applicable investment capital account, registration, and notification procedures. Funds repatriated to Vietnam must pass through the investor’s designated investment capital account. The procedures for reusing overseas profits differ according to their intended use.

Where the Singapore entity invests in another business in Singapore or a third country, the Vietnamese investor must also assess the outward-investment reporting requirements.

Singapore can consequently serve as a platform for overseas reinvestment, provided the arrangements comply with the requirements in both jurisdictions.

What tax issues arise for a Singapore holding company?

A holding company’s receipts may include dividends, interest, service income, and gains on selling investments. Each category requires its own analysis.

Singapore tax-resident companies may qualify for exemption on specified foreign-sourced income received in Singapore: foreign dividends, foreign branch profits, and foreign service income. Conditions include a subject-to-tax test, a foreign headline corporate tax rate of at least 15 percent, and the Comptroller’s assessment that exemption is beneficial to the company.

This is not a blanket exemption for foreign receipts. An overseas customer or payment source does not, by itself, make service income foreign-sourced or eligible for exemption.

Singapore currently does not impose withholding tax on dividends. The shareholder’s tax obligations in Vietnam or another jurisdiction must still be considered.

Incorporation does not establish tax residence

Singapore corporate tax residence depends on where control and management are exercised, including where strategic business decisions are made.

Foreign-owned passive investment holding companies that follow overseas owners’ instructions are generally not treated as Singapore tax residents, although they may qualify where the relevant conditions are satisfied. A local address, nominee director, or formal board meeting alone should not be assumed to establish residence.

Any reliance on the Singapore–Vietnam tax treaty requires assessment of the relevant income provisions, residence, and applicable anti-abuse conditions.

Exit planning is equally important. Singapore’s foreign-sourced disposal gains rules can tax certain gains received in Singapore by covered entities. Adequate economic substance can exclude relevant non-intellectual-property gains from this regime, while intellectual-property gains have separate treatment.

For established international trading businesses, the Global Trader Programme may warrant assessment. It requires approval and commitments to substantial Singapore activities, skilled professionals, and strategic functions. Incorporating a trading company does not automatically qualify it for the programme.

Is this comparable to a China–Hong Kong structure?

The comparison is useful at the level of business organisation. Production can remain in one market while an international hub coordinates selected sales, financing, investment, and ownership functions.

For Vietnamese businesses, Singapore may play that coordinating role while factories and production expertise remain in Vietnam. A manufacturer can develop regional capabilities without relocating its entire operation.

The legal and tax outcomes cannot be assumed to match a China–Hong Kong arrangement. Outward-investment rules, foreign-exchange requirements, treaty provisions, and restructuring procedures differ. Hong Kong’s own foreign-sourced income exemption regime also imposes conditions on relevant income received by in-scope multinational entities.

Businesses should therefore design the structure around their commercial needs and assess the rules in each relevant jurisdiction.

How can a holding company support succession planning?

International expansion can make ownership and succession more complex, particularly where a founder has several children, brings in professional managers or external investors, or has family members living in different countries.

A Singapore holding company can bring ownership of several businesses under one entity, allowing succession arrangements to focus on shares in that company. Its constitution and shareholder agreements can set out voting rights, decisions requiring shareholder approval, share-transfer restrictions, dividend policies, and procedures following an owner’s death or incapacity.

A trust may help maintain continuity by allowing a trustee to hold shares for designated beneficiaries. A family office serves a different purpose: it manages family wealth and related affairs. The appropriate structure depends on the assets, family circumstances, and ongoing costs and administration.

Singapore removed estate duty for deaths on or after 15 February 2008. However, cross-border families must still consider inheritance, probate, matrimonial, and tax rules in other relevant jurisdictions.

Any intended asset protection also requires careful assessment. Guarantees, assets pledged as security, and liabilities within the structure can affect how effectively business and family assets are separated.

Ownership and control must also remain transparent. Unless exempt, Singapore companies must maintain a register of registrable controllers—persons or entities with significant ownership or control—and file the required information with the Accounting and Corporate Regulatory Authority (ACRA). They must also send annual notices asking controllers to confirm their details and keep the records accurate and up to date.

What should Vietnamese businesses assess before proceeding?

The starting point is the business objective: regional sales, an acquisition, investment ownership, financing coordination, or succession.

Before implementation, businesses should:

• Map the proposed ownership chain and identify whether the Vietnamese investor is a company or an individual.
• Confirm applicable investment procedures, foreign-exchange registration, capital account, reporting, and profit-repatriation requirements.
• Allocate commercial functions and decision-making authority between Vietnam and Singapore.
• Model tax, transfer pricing, staffing, and annual operating costs.
• Align contracts, financial flows, shipping documents, and governance records.
• Assess downstream investments and acquisitions against Vietnamese reporting requirements.
• Review succession arrangements separately from day-to-day trading needs.

A Singapore structure is most useful when it solves a defined commercial or ownership problem. For Vietnamese manufacturers and exporters, that may mean building regional customer relationships, managing overseas investments, or preparing the business for its next generation of owners. Its benefits depend on genuine activity, clear governance, and coordinated implementation in both countries.
