Short answer. There is no single correct answer — the three jurisdictions solve different problems. Singapore combines a moderate 17% headline corporate tax rate (reduced further by a start-up exemption offering 75% relief on the first S$100,000 of profit for three years) with the deepest treaty network and highest reputational credibility among institutional counterparties and banks, at the cost of requiring a resident director and company secretary. Hong Kong offers a competitive two-tier rate (8.25% on the first HK$2 million of profit, 16.5% above) and strong access into Greater China, with broadly comparable director and secretarial requirements to Singapore, plus a mandatory annual audit. Dubai/UAE offers the lowest effective tax exposure — 9% above AED 375,000 of profit, 0% below, and 0% on Qualifying Free Zone income where substance and filing conditions are met — with no resident-director requirement, but structurally higher annual free-zone licence fees and a comparatively newer, less internationally tested regulatory track record than the other two. The right choice depends on the specific commercial function the holding entity performs — treaty access, banking relationships, tax efficiency, or a combination — not on which jurisdiction is currently most fashionable.
What each jurisdiction is actually being used for
Vietnamese businesses expanding internationally, or seeking a cleaner structure for cross-border investment, licensing, or exit optionality, typically consider Singapore, Hong Kong, or Dubai as a holding-company location — but the three are not interchangeable, and choosing between them properly starts from the commercial function the structure needs to perform, not from headline tax rates in isolation.
Tax and incorporation cost, compared
Singapore. A 17% headline corporate tax rate applies, but a start-up tax exemption scheme reduces this materially for new entities — a 75% exemption on the first S$100,000 of normal chargeable income for each of the first three consecutive tax years, bringing the effective early-years rate well below the headline figure. Incorporation is fast, typically one to three business days once documentation is ready, with government fees and professional costs broadly comparable to Hong Kong.
Hong Kong. Hong Kong applies a two-tier profits tax: 8.25% on the first HK$2 million of assessable profit, rising to 16.5% above that threshold. Incorporation typically takes three to seven business days. Hong Kong additionally requires a mandatory annual audit regardless of company size, which adds a recurring compliance cost not present in the same form in Singapore or the UAE free zones.
Dubai/UAE. Federal corporate tax applies at 9% on profit above AED 375,000, with 0% below that threshold, and — significantly for a holding structure — 0% on Qualifying Free Zone Person (QFZP) income where the entity meets defined substance, qualifying-activity, and filing conditions. Free-zone incorporation typically takes one to two weeks and carries structurally higher recurring cost than Singapore or Hong Kong, with annual free-zone licence fees generally in the range of AED 12,000 to 30,000, before professional fees.
Substance requirements and what they mean in practice
Singapore requires at least one resident director and a qualified company secretary, underpinned by ACRA's transparent corporate registry and a common-law court system that institutional counterparties and international banks generally treat as a strong credibility signal. Hong Kong's requirements are broadly comparable — a director of any nationality, a local company secretary, and a designated representative for regulatory purposes — alongside the mandatory audit noted above. The UAE free-zone model does not impose an equivalent resident-director requirement; instead, the operative constraint is holding the correct free-zone licence and registered agent for the zone in question, and — critically for anyone relying on the 0% QFZP rate — genuinely meeting the qualifying-activity and substance conditions on an ongoing basis, since failing to do so converts the exposure from 0% to the standard 9% rate rather than merely triggering a penalty.
Which jurisdiction is cheapest to set up a holding company in?
Singapore is generally the fastest and among the lowest-cost to incorporate, at roughly one to three business days; Dubai free-zone incorporation is typically the most expensive on a recurring basis due to annual free-zone licence fees, even though its effective tax rate can be lower.
Does Dubai really offer 0% tax on holding company income?
Only on Qualifying Free Zone Person (QFZP) income where the entity meets specific substance, qualifying-activity, and ongoing filing conditions — failing to maintain those conditions moves the income to the standard 9% federal corporate tax rate above the AED 375,000 threshold.
Why would a company choose Hong Kong over Singapore if the tax rates are similar?
Primarily for proximity and access into Greater China markets and banking relationships, where Hong Kong's positioning is a distinct commercial advantage regardless of the marginal tax-rate difference between the two.
Do these jurisdictions require a physical office?
Requirements vary by jurisdiction and by the specific substance conditions relevant to the entity's tax treatment (particularly for UAE QFZP status); a registered address alone is not always sufficient once substance requirements are engaged, and this should be assessed on the specific structure rather than assumed.
Can a Vietnamese company use one of these structures to hold its Vietnamese operating entity as well as future international ventures?
Yes, this is one of the most common uses of an outbound holding structure — consolidating ownership of a Vietnamese operating company alongside new international entities under a single holding vehicle for financing, exit, and governance purposes.
How does JMT Private & Partners assist with outbound structuring?
JMT advises on jurisdiction selection based on the specific commercial function required, coordinates incorporation with partner firms in Singapore, Hong Kong, and the UAE, and integrates the resulting structure with the client's existing Vietnamese entity, as part of its Business Related Advisory service line.
