Quick Answer
Singapore offers e-commerce sellers a single GST framework, no capital gains tax, proximity to Asian manufacturing and strong cross-border fulfillment infrastructure. The US offers the world's largest consumer market and mature marketplace ecosystems, but its sales tax nexus complexity (45+ states with different rules) creates a compliance burden that scales with every sale. Savvy Platform helps e-commerce founders incorporate in Singapore through SavvyStart, with a local nominee director, company secretary and compliance support included.
Why E-Commerce Sellers Compare Singapore and the US
E-commerce operators and D2C brands need a corporate base that optimises three things: tax efficiency on sales, logistics infrastructure for fulfillment, and payment gateway access for global customers.
The US is the obvious choice if you sell primarily to American consumers. Singapore is the stronger choice if you sell globally, source from Asia, or want to avoid the multi-state sales tax system that defines US e-commerce compliance.
The US Sales Tax Nexus Problem
This is the single biggest compliance headache for e-commerce sellers operating through a US entity.
How it works
Since the 2018 South Dakota v. Wayfair Supreme Court ruling, US states can require out-of-state sellers to collect and remit sales tax based on economic activity. The standard threshold is $100,000 in sales or 200 transactions per year in a state.
Why it scales out of control
A typical e-commerce brand generating $500K to $2M in annual revenue ends up registered for sales tax in 25 to 35 states. Each state has:
- Different tax rates (ranging from 0% to over 10%)
- Different nexus thresholds (most $100,000, but California is $500,000)
- Different product taxability rules (some states tax digital goods, others do not)
- Different filing frequencies (monthly, quarterly or annually)
- Different definitions of what counts toward the threshold (gross sales vs taxable sales)

For a seller using Amazon FBA, the problem is even worse: Amazon's warehouses create physical nexus in every state where your inventory is stored, regardless of whether you chose those locations.
The real cost
Sales tax compliance software (TaxJar, Avalara, TaxCloud) costs $500 to $5,000+ per year. CPA fees for multi-state filing add another $2,000 to $10,000+ annually. A $1M e-commerce brand can easily spend $5,000 to $15,000 per year just on sales tax compliance.

Most early-stage e-commerce brands operating through a Singapore entity do not need to register for GST at all because they are below the S$1M threshold. When they do register, it is one rate applied nationwide with quarterly filing to a single authority.
The contrast is stark: 1 jurisdiction with 1 rate versus 45+ jurisdictions with 11,000+ rate variations.

For a profitable e-commerce brand, Singapore's combined tax burden is significantly lower. A brand earning S$200,000 in profit pays approximately S$8,375 in Singapore after SUTE exemptions. The same profit in a US C-Corp pays approximately US$42,000 in federal tax alone, before state income taxes and the sales tax compliance overhead.
Logistics and Fulfillment
E-commerce sellers need to ship products to customers, which means the corporate base matters for supply chain proximity and fulfillment infrastructure.
Sourcing from Asia
Most e-commerce brands source products from China, Vietnam, Thailand or other Southeast Asian manufacturers. Singapore sits at the centre of this supply chain.

Selling globally from either jurisdiction
Both Singapore and the US support global e-commerce sales. The corporate base does not limit where you sell. The question is which base is more efficient for your supply chain and compliance.

IP and Brand Protection
E-commerce brands face counterfeiting on marketplaces and social media. Singapore's common law system and IPOS trademark registration provide strong protection. Platform takedown tools on Shopee and Lazada are more accessible for Singapore-registered IP holders.
In the US, trademark registration through USPTO is strong but enforcement (particularly against overseas counterfeiters) is expensive and slow. Amazon Brand Registry works in both jurisdictions.
When the US Is the Better Base for E-Commerce
The US is the stronger choice for sellers who:
- Generate 70%+ of revenue from US consumers
- Use Amazon FBA as their primary fulfillment channel
- Need deep integration with US-specific marketplace features
- Are US tax residents who benefit from QSBS on exit
When Singapore Is the Better Base
Singapore is the stronger choice for sellers who:
- Source products from China, Vietnam or Southeast Asia
- Sell globally (US, EU, Asia) rather than primarily to one market
- Want to avoid the 45-state sales tax compliance system
- Need multi-currency banking and Asian payment integration
- Sell on Shopee, Lazada or TikTok Shop in Southeast Asia
- Want lower overall tax burden and no capital gains tax on exit

Conclusion
The US offers unmatched domestic market access for e-commerce sellers targeting American consumers. But for sellers who operate globally, source from Asia, and sell across multiple markets, the US sales tax system creates a compliance burden that scales with every sale in every state. Singapore provides a single GST framework, supply chain proximity, multi-currency banking and lower overall taxation. Savvy Platform makes Singapore incorporation straightforward for e-commerce founders.
FAQ
How many states will I need to register for sales tax?
A typical $500K to $2M e-commerce brand ends up registered in 25 to 35 US states. Each requires separate registration, tax collection and filing on different schedules.
Does Singapore have sales tax?
Singapore has GST at 9%, with a registration threshold of S$1 million in taxable turnover. Most early-stage e-commerce brands are below this threshold and do not need to register.
Can I sell on Amazon US from a Singapore company?
Yes. Amazon supports international sellers. You can list products, use FBA and sell to US consumers from a Singapore-incorporated entity.
Does Amazon FBA create sales tax obligations?
Yes. Amazon warehouses create physical nexus in every state where your inventory is stored. This triggers sales tax collection and filing obligations in those states, regardless of where your company is incorporated.
Is Singapore closer to my suppliers?
If you source from China, Vietnam, Thailand or other Southeast Asian manufacturers, Singapore is 3 to 6 hours away by flight versus 12 to 18 hours from the US.
Can I use Stripe and Shopify with a Singapore company?
Yes. Both Stripe and Shopify fully support Singapore-incorporated companies. Multi-currency payment processing is standard.
What is the total tax burden difference?
A Singapore startup earning S$200,000 pays approximately S$8,375 in corporate tax. The same profit in a US C-Corp pays approximately US$42,000 in federal tax, before state taxes and sales tax compliance costs.
Does Savvy Platform support e-commerce businesses specifically?
Yes. SavvyStart includes incorporation, local nominee director, company secretary and banking setup designed for e-commerce operators who need a compliant corporate base without multi-state US complexity.
