Can a Singapore Company Sell Into the US Market Without a US Entity?

Quick Answer

Yes. A Singapore company can sell products and services to US customers, accept USD payments, sign contracts with US clients and operate in the US market without incorporating a US entity. A US entity becomes necessary only when the company triggers physical or economic nexus, hires US employees, or needs US regulatory licensing. Savvy Platform helps founders incorporate in Singapore through SavvyStart, providing a corporate base from which to serve US customers without the compliance overhead of a US entity.

Why This Question Matters

The biggest objection founders raise when choosing Singapore over the US is: "But my customers are in America." The assumption is that selling to US customers requires a US company. For most businesses, this is not true.

A Singapore Pte Ltd can:

• Invoice US customers in USD
• Accept payments via Stripe, PayPal, Wise or wire transfer
• Sign contracts with US companies
• Sell on Amazon US as an international seller
• Operate a Shopify store serving US consumers
• Provide SaaS to US subscribers
• Offer consulting services to US clients

None of these activities require a US entity unless they trigger specific tax or regulatory thresholds.

When You Do Not Need a US Entity

Selling services remotely

A Singapore-based consultant, agency or SaaS company billing US clients remotely does not need a US entity. The services are performed outside the US, the company has no physical presence, and the income is not US-sourced for tax purposes.

Selling physical products via your own website

A Singapore company selling products to US customers through its own Shopify or D2C store does not need a US entity, provided it ships from outside the US (or uses a third-party fulfillment service that does not create nexus).

Selling on Amazon US as an international seller

Amazon supports international sellers. A Singapore company can register as a seller on Amazon US, list products and sell to American consumers. However, using Amazon’s FBA (“fulfilled by Amazon”) option creates a specific complication (covered below).

Licensing software or IP

A Singapore company that licenses software, content, or intellectual property to US clients does not need a US entity. Royalty and licence payments flow from the US client to the Singapore company under the terms of the licence agreement.

The Nexus Question

Nexus is the legal threshold that determines when a foreign company has sufficient connection to a US state to trigger tax obligations. There are two types.

Physical nexus

Activity that creates physical nexus	Does it require a US entity?
Office or warehouse in a US state	Yes, likely
Employees working in a US state	Yes, likely
Inventory stored in a US state (including Amazon FBA)	Creates sales tax nexus
Independent contractors in the US	Generally does not create nexus
Travelling to the US for client meetings	Generally does not create nexus (short-term visits)

Economic nexus (sales tax)

Since the 2018 Wayfair ruling, most US states impose sales tax collection obligations on out-of-state sellers who exceed economic thresholds.

Factor	Detail
Standard threshold	$100,000 in sales or 200 transactions per state per year
Number of states with economic nexus	45 + DC
What it triggers	Obligation to collect and remit sales tax in that state
Does it require a US entity?	No. Sales tax registration is possible without a US entity.
Practical impact	Administrative burden of multi-state registration and filing

Economic nexus does not require you to incorporate in the US. It requires you to register for sales tax collection in each state where you exceed the threshold. This is an administrative obligation, not a corporate structure requirement.

Many SaaS companies and e-commerce brands handle this by using sales tax automation software (TaxJar, Avalara) from their Singapore entity, without creating a US company.

The Amazon FBA Exception

Amazon FBA is the one scenario where selling to US customers from a Singapore entity creates unexpected complications.

When you send inventory to Amazon FBA, Amazon distributes it across warehouses in multiple US states. This creates physical nexus for sales tax purposes in every state where your inventory is stored.

Amazon FBA impact	Detail
Inventory placement	Amazon decides which states to store your products
Sales tax nexus created	In every state with your inventory
Registration required	Sales tax registration in all nexus states
Can be managed without a US entity	Yes, but complex
Common solution	Register for sales tax from a Singapore entity, or create a lightweight US LLC for FBA operations

For high-volume Amazon FBA sellers, a Wyoming or Delaware LLC as a subsidiary of the Singapore parent is a common solution. The LLC handles FBA and US sales tax, while the Singapore entity remains the primary corporate base.

Payment Processing Without a US Entity

Payment method	Works from Singapore?	Notes
Stripe	Yes	Full support for Singapore companies, accepts USD
PayPal Business	Yes	Full support, multi-currency
Wise Business	Yes	Multi-currency, competitive FX
Wire transfer (SWIFT)	Yes	DBS, OCBC, UOB all support USD wires
Amazon Seller payments	Yes	Amazon pays international sellers in their local currency or USD
Shopify Payments	Yes	Supported in Singapore
Apple App Store / Google Play	Yes	Both support Singapore-incorporated developers

There is no payment processing barrier to serving US customers from a Singapore entity. Stripe, PayPal and Shopify all fully support Singapore companies accepting USD payments.

Contracts and Legal Enforceability

US clients and their legal teams routinely sign contracts with non-US entities. A contract governed by Singapore law is enforceable, and many international contracts include arbitration clauses (SIAC in Singapore, or neutral venues like ICC) rather than relying on US courts.

Contract factor	Singapore entity selling to US client
Contract validity	Fully valid under both Singapore and US law
Governing law options	Singapore law, US state law, or neutral jurisdiction
Dispute resolution	SIAC arbitration, ICC arbitration, or agreed court jurisdiction
Client perception	Singapore Pte Ltd is widely recognised by US enterprise legal teams
MSA and SOW format	Standard international format, no US-specific requirements

For enterprise sales, some US clients prefer a US contract vehicle. In these cases, a lightweight US subsidiary can be added later without restructuring the Singapore parent.

US Tax Implications of Selling from Singapore

No US corporate tax if no US nexus

A Singapore company with no physical presence, no US employees and no US office is generally not subject to US federal corporate tax. Income from selling to US customers remotely is not considered Effectively Connected Income (ECI) in most cases.

Withholding tax on certain payments

Payment type	US withholding tax	Treaty rate (US-SG)
Service fees (no US presence)	Generally none	N/A
Royalties	30% default	0% under US-SG treaty
Interest	30% default	0-15% under treaty
Dividends from US subsidiary	30% default	5-15% under treaty

When You Should Add a US Entity

A US entity becomes worthwhile when:

• US revenue exceeds $500K+ and US-specific operations justify the compliance cost
• You hire US employees (payroll, benefits, state employment law)
• Enterprise clients require a US contract vehicle
• You use Amazon FBA at scale (physical nexus in multiple states)
• US regulatory licensing is required (fintech, healthcare, defence)
• You plan to raise from US VCs who require a US entity

The key principle: add a US entity when US-specific operations justify the cost, not as a default assumption.

The Recommended Approach

Stage	Structure
Pre-revenue to $500K US revenue	Singapore entity only, serve US customers remotely
$500K to $2M US revenue	Evaluate whether a US subsidiary is justified
$2M+ US revenue or US employees	Add a lightweight US subsidiary (LLC or C-Corp) under the Singapore parent
US enterprise sales requiring US contract vehicle	Add a US subsidiary for US contracts, keep Singapore as HoldCo

Most founders can operate from Singapore alone for the first one to three years of US market entry. Adding a US entity later is straightforward and cheaper than restructuring from US to Singapore.
