You Don't Need to Choose: How to Structure a Singapore + US Dual-Entity Setup

Quick Answer

A Singapore + US dual-entity setup allows founders to use Singapore as the holding company, IP home and international operations base while maintaining a US subsidiary for American market access. This avoids the compliance overhead of running everything through a US entity and preserves the tax efficiency of Singapore for global operations. Savvy Platform helps founders set up the Singapore side of a dual-entity structure through SavvyStart, with nominee director, company secretary and compliance support included.

Why a Dual-Entity Structure Exists

Many founders face a false choice: Singapore or the US. In reality, businesses with global operations and US customers often benefit from having both.

The logic is simple:

• Singapore handles global operations, IP ownership, international contracts and treasury
• The US subsidiary handles American market revenue, US customer contracts and local compliance
• Profits from global operations stay in the lower-tax, simpler-compliance Singapore entity
• US compliance costs are limited to the US subsidiary's actual American operations

This is standard corporate structuring used by companies from early-stage startups to multinationals.

The Three Common Structures

Structure 1: Singapore Holding Company + US subsidiary

The Singapore Pte Ltd is the parent company. It owns 100% of a US subsidiary (typically a Delaware LLC or C-Corp). The US entity operates in the American market. The Singapore entity handles everything else.

Entity	Role	What it handles
Singapore Pte Ltd (parent)	Holding company, IP owner, international operations	Global contracts, IP licensing, treasury, investor equity, non-US revenue
US LLC or C-Corp (subsidiary)	US operating entity	US customer contracts, US revenue, US compliance

This is the most common structure for non-US founders. Investors hold equity in the Singapore parent. US operations are ring-fenced in the subsidiary.

Structure 2: US parent + Singapore subsidiary

The US C-Corp is the parent. It owns a Singapore Pte Ltd for Asia-Pacific operations. This structure is typical when the company was originally incorporated in the US and later expanded to Asia.

Entity	Role	What it handles
US C-Corp (parent)	Holding company, US operations	US revenue, US investor equity, US compliance
Singapore Pte Ltd (subsidiary)	Asia-Pacific operations	Regional contracts, Asia-Pacific revenue, regional compliance

This structure makes sense when 70%+ of revenue is from the US and the founding team is US-based.

Structure 3: Parallel entities

Two independent entities, same founders. No parent-subsidiary relationship. Each entity operates independently in its own market.

Entity	Role	What it handles
Singapore Pte Ltd	International operations	Non-US revenue, IP, international contracts
US LLC or C-Corp	US operations	US revenue, US contracts, US compliance

This is simpler to set up but harder to manage. Transfer pricing is less of an issue because there are no intercompany transactions, but it creates two separate compliance tracks and two separate bank accounts with no structural connection.

Where to Domicile IP

IP domicile is one of the most important decisions in a dual-entity structure.

Factor	Singapore	United States
IP Box regime	IDI: 5-10% tax on qualifying IP income	No equivalent
R&D deductions	Up to 400% (EIS)	Immediate expensing (domestic), 15-year amortisation (foreign)
Capital gains on IP sale	None	21% federal + state
Royalty withholding on payments to Singapore	0% (US-SG treaty)	N/A
Licensing flexibility	Singapore entity licenses IP to US subsidiary	US entity licenses IP to Singapore subsidiary

For most non-US founders, domiciling IP in Singapore provides clear tax advantages. The Singapore entity owns the IP and licenses it to the US subsidiary. Royalty payments from the US subsidiary to Singapore reduce US taxable income, while Singapore taxes the royalty income at favourable IDI rates.

The intercompany licence agreement must be on arm's-length terms to comply with transfer pricing rules in both jurisdictions.

Transfer Pricing Basics

Any transaction between the Singapore parent and US subsidiary must be priced as if the two entities were unrelated parties. This is the arm's-length principle.

Intercompany transaction	Transfer pricing consideration
IP licence (royalties)	Royalty rate must reflect market value of the IP
Management fees	Fees for services provided must match what an independent provider would charge
Intercompany loans	The interest rate must be at the market rate
Cost-sharing arrangements	Each entity's share of costs must reflect its share of expected benefits

Both Singapore (IRAS) and the US (IRS) enforce transfer pricing rules. Documentation is essential. A transfer pricing memo prepared at the time of structuring protects against challenges from either tax authority.

For early-stage startups with minimal intercompany transactions, transfer pricing is straightforward. It becomes more complex as revenue grows and more value flows between entities.

Tax Flow in a Dual Structure

Here is how profits typically flow in a Singapore HoldCo + US subsidiary structure.

Step	What happens	Tax impact
US subsidiary earns revenue from US customers	US revenue taxed at 21% federal + state	US corporate tax applies
US subsidiary pays royalty to Singapore parent for IP licence	Royalty is deductible expense in the US	Reduces US taxable income
Singapore parent receives royalty income	Taxed at IDI rate (5-10%) or standard rate (17%, effective ~4.25-8.5% for startups)	Singapore corporate tax applies
Singapore parent earns non-US revenue directly	Taxed at Singapore rates	No US tax involvement
Singapore parent distributes dividends to shareholders	No withholding tax	Zero dividend tax
US subsidiary distributes dividends to Singapore parent	30% withholding tax

The key advantage: non-US revenue never touches the US tax system. Only US-source revenue is subject to US tax. Global profits flow up to Singapore where there is no capital gains tax and no dividend withholding.

Compliance Comparison: Dual vs Single US Entity

Compliance item	Single US entity	Dual structure (SG HoldCo + US sub)
US federal tax return	Required	Required (US subsidiary only)
US state tax returns	All nexus states	Only states where US subsidiary has nexus
US sales tax	All nexus states	Only states where US subsidiary triggers nexus
FBAR/FATCA	If applicable	US subsidiary files, Singapore parent not subject
Form 5471	N/A	Required (US person with foreign corporate interest)
Singapore ACRA filing	N/A	One annual return
Singapore tax return	N/A	One filing (Form C-S)
Transfer pricing documentation	N/A	Required for intercompany transactions
Total compliance cost	US$5,000-15,000+	US$7,000-20,000 (combined, but non-US revenue taxed at lower rates)

The dual structure adds some compliance (Form 5471, transfer pricing documentation, Singapore filings), but it reduces US tax exposure on non-US revenue and provides lower overall effective tax rates.

When a Dual Structure Makes Sense

A dual structure is the right approach when:

• 30-60% of revenue comes from the US, with meaningful non-US revenue
• The company has IP that generates licensing income
• Investors are international (not exclusively US-based)
• The founder wants to keep non-US profits outside the US tax system
• The company plans to expand into Asia-Pacific markets
• Long-term exit planning benefits from Singapore's zero capital gains tax

When a Single Entity Is Sufficient

A single entity (either Singapore or US) is sufficient when:

• 90%+ of revenue comes from one market
• Intercompany complexity is not justified by the tax savings
• The company is pre-revenue and wants to minimise setup costs
• The founder plans to consolidate everything into one jurisdiction eventually

FAQ

Which entity should be the parent?

For non-US founders with global operations, Singapore as the parent (HoldCo) is typically more tax-efficient. For US-based founders expanding to Asia, the US as the parent may be simpler initially.

Where should IP be domiciled?

Singapore, in most cases. The IDI regime (5-10% tax on qualifying IP income), zero capital gains and 400% R&D deductions make it the more efficient jurisdiction for IP ownership.

Do I need transfer pricing documentation?

Yes. Any intercompany transaction (royalties, management fees, loans) must be documented at arm's-length terms. Both IRAS and the IRS enforce transfer pricing rules.

How much does a dual structure cost to set up?

The Singapore entity costs S$2,500-6,000 in the first year through Savvy Platform. The US subsidiary costs US$500-2,000 to incorporate. Ongoing combined compliance is US$7,000-20,000 per year.

Can I start with one entity and add the second later?

Yes. Many founders start with Singapore and add a US subsidiary when US revenue justifies it, or vice versa. Savvy Platform supports both initial setup and later additions.

Is this structure legal and transparent?

Yes. Dual-entity structures are standard corporate practice. Both entities are fully regulated, onshore and compliant with their respective jurisdictions.

Does Savvy Platform handle the US side?

No. Savvy Platform manages the Singapore entity. The founder works with US counsel for the US subsidiary. Both sides can be set up in parallel.

What is Form 5471?

Form 5471 is a US information return required for US persons with interests in foreign corporations. If the US subsidiary is owned by a Singapore parent, and any US person has an interest, Form 5471 may be required.
