Cross-border e-commerce sellers generating revenue in the United States face a critical decision: how to structure their US operations in a way that is tax-efficient, compliant, and operationally advantageous. The wrong structure can result in effective tax rates exceeding 45%, while the right one can bring the US tax burden down to less than 1% of revenue, all within the boundaries of the law.

In this article, we explain the key tax and operational considerations for e-commerce businesses operating in the US market from jurisdictions like Hong Kong, the Netherlands, or the UAE. We cover the risks of commonly used structures, how transfer pricing works in practice, and why a US entity may offer significant commercial advantages beyond tax savings alone.

1. The common setup: why it is risky

A structure we frequently encounter among e-commerce entrepreneurs looks something like this: a holding company in Hong Kong or the UAE owns a single-member US LLC. The LLC opens US bank accounts, connects to payment processors like Stripe or Shopify Payments, and sells products to American consumers through platforms such as Amazon and Shopify. The entrepreneur, often a tax resident of Dubai or another low-tax jurisdiction, assumes the LLC is “tax-free” because LLCs are not subject to US income tax at the entity level.

This assumption is a half-truth. And half-truths in international tax law can be very expensive.

While it is correct that a single-member LLC is not itself a taxable entity for US federal income tax purposes, the income does not simply disappear. It flows through to the owner. If that owner is a foreign corporation or individual, the US tax consequences can be severe, depending on how the LLC is classified and what activities it performs in the United States.

2. The disregarded entity trap

By default, a single-member LLC owned by a foreign person is classified as a “disregarded entity” (DRE) for US federal income tax purposes. This means the LLC is transparent, the IRS looks through it and treats the foreign owner as directly conducting business in the United States.

Effectively connected income (ECI)

When a foreign owner conducts a trade or business in the US through a disregarded LLC, for example, by holding inventory in US warehouses, fulfilling orders to US customers, or using a third-party logistics provider (3PL) that acts as a dependent agent, the resulting income is classified as effectively connected income (ECI). ECI is subject to US federal income tax at regular rates: up to 37% for individuals, or 21% for corporations.

The determination of whether a 3PL creates a dependent agency relationship, and therefore a permanent establishment, depends on the specific facts and circumstances. If the 3PL regularly fills orders, maintains inventory, and performs core business functions exclusively for one foreign company, its activities may be imputed to the foreign owner.

Branch profits tax (BPT)

On top of the regular income tax, a foreign corporation operating through a US branch (including a disregarded LLC) is subject to the branch profits tax (BPT) under IRC Section 884. The BPT imposes an additional 30% tax on the “dividend equivalent amount”, essentially the after-tax earnings deemed remitted to the foreign home office.

This second layer of tax is analogous to the withholding tax on dividends paid by a US subsidiary to a foreign parent. Critically, the statutory BPT rate can be reduced by an applicable tax treaty. The US-Netherlands treaty, for example, typically reduces the BPT rate significantly. However, there is no US-Hong Kong tax treaty, meaning Hong Kong-based owners face the full 30% BPT rate.

The combined effect for a Hong Kong company operating through a US disregarded LLC can be staggering: 21% corporate income tax plus 30% BPT on the remaining 79% results in an effective tax rate of approximately 45% on US-source income. And if the foreign owner fails to file a timely Form 1120-F, it may lose the right to claim deductions, meaning the tax applies to gross revenue, not net profit.

3. The C-Corporation solution

The structural problems described above can be largely resolved through a single election: having the US LLC elect to be treated as a C-Corporation for US federal income tax purposes by filing IRS Form 8832 (the “check-the-box” election).

How it works

Once the election is made, the LLC is treated as a separate US domestic corporation. It files its own tax return (Form 1120), pays the flat 21% federal corporate income tax on its taxable income, and, crucially, is no longer a branch of the foreign owner. This eliminates the branch profits tax entirely.

Instead, a withholding tax applies only when dividends are actually distributed to the foreign parent. The statutory rate is 30%, but treaty rates often reduce this significantly. More importantly, if the US entity retains its earnings and reinvests them into the business, no second layer of tax arises at all.

This distinction is significant in practice. Under a properly implemented transfer pricing arrangement, the US entity earns only a routine profit margin of 1% to 5% of revenue. When dividends are eventually distributed, the withholding tax applies only to this limited amount, not to the full revenue stream. By contrast, in a disregarded entity structure the full profit of the US operations is treated as effectively connected income of the foreign owner, meaning the foreign owner is subject to US income tax on the entire net profit, not just a routine margin. On top of that, the BPT applies to all after-tax profits attributable to the US branch, which typically represents a far larger base. The C-Corporation structure therefore not only defers the second layer of tax but also significantly reduces the amount subject to it. The applicable withholding rate on dividends depends on the tax treaty between the US and the parent company’s jurisdiction. The US-Netherlands treaty, for instance, can reduce the rate to as low as 5% for qualifying participations. However, there is no comprehensive income tax treaty between the US and Hong Kong, nor between the US and the UAE, meaning that in these structures the statutory 30% withholding rate applies in full upon dividend distribution.

Key advantages

• No branch profits tax — BPT only applies to branches of foreign corporations, not to US domestic corporations
• Deferral of dividend withholding — the second layer of tax is triggered only upon actual distribution, not accrual
• Cleaner compliance profile — the entity files Form 1120 (standard US corporate return), not Form 1120-F
• Transfer pricing flexibility — the C-Corp structure enables a defensible transfer pricing arrangement where the US entity earns only a routine profit margin
• Foreign ownership permitted — foreign nationals can own 100% of a US C-Corporation without any citizenship or residency requirements

4. Corporate tax landscape: US vs Hong Kong

United States

The US imposes a flat 21% federal corporate income tax on the worldwide income of domestic corporations. In addition, most states impose their own corporate income tax, with rates ranging from 0% (in states like Nevada, South Dakota, and Wyoming) to over 9% (in states like New Jersey and California). State tax planning, including the choice of incorporation state, is therefore an important consideration.

The US does not impose a federal VAT or sales tax, but nearly all states impose sales and use taxes that e-commerce sellers must collect and remit once they exceed certain economic nexus thresholds (typically $100,000 in sales or 200 transactions, following the South Dakota v. Wayfair decision).

Hong Kong

Hong Kong operates on a territorial basis of taxation: only profits arising in or derived from Hong Kong are subject to profits tax. The two-tier profits tax rates are:

• First HKD 2,000,000 (~USD 256,000) of assessable profits: 8.25%
• Profits exceeding HKD 2,000,000: 16.5%

There is no capital gains tax, no withholding tax on dividends, and no sales tax or VAT in Hong Kong. For e-commerce businesses selling primarily to customers outside Hong Kong, profits may be considered offshore-sourced and potentially exempt from Hong Kong profits tax, provided the business can demonstrate genuine economic substance in Hong Kong.

The FSIE regime

Since 1 January 2023, Hong Kong has implemented the Foreign-Sourced Income Exemption (FSIE) regime to align with EU and OECD standards. The regime targets four types of passive offshore income received by multinational enterprise (MNE) entities in Hong Kong: dividends, interest, disposal gains from equity interests, and intellectual property income. From 1 January 2024, its scope was expanded to include disposal gains on non-equity assets.

These income types are now deemed Hong Kong-sourced and taxable unless the entity meets an economic substance test, demonstrating adequate employees, expenditure, and decision-making in Hong Kong, or qualifies under specific exemptions such as the participation exemption for dividends and gains.

5. Transfer pricing: how it works for e-commerce

Transfer pricing is the mechanism by which related entities within a multinational group price their intercompany transactions. Under both the OECD Transfer Pricing Guidelines and US domestic law (IRC Section 482), these transactions must be priced at arm’s length, meaning the price must reflect what unrelated parties would have agreed upon under comparable circumstances.

For cross-border e-commerce structures, transfer pricing is the tool that determines how much profit is allocated to the US entity and how much remains with the foreign parent.

The limited-risk distributor model

A common and well-established transfer pricing model for e-commerce involves characterizing the US entity as a limited-risk distributor (LRD). In this arrangement:

• The foreign parent owns the brand, product intellectual property, and customer data. It selects products, manages supplier relationships, makes strategic decisions, and bears the entrepreneurial risk.
• The US entity acts as a limited-risk distributor: it purchases goods from the foreign parent (or receives them on consignment), fulfills orders through Amazon FBA or its own logistics, handles US customer service, and collects payments.

Because the US entity performs only routine distribution functions and bears limited risk, it is entitled to earn only a routine profit margin under arm’s-length principles. Based on benchmarking analyses of comparable independent distributors, this margin typically falls in the range of 1% to 5% of net sales, with 2% to 3% being the most commonly observed interquartile range for limited-risk distributors.

The remaining profit flows to the foreign parent through intercompany pricing, the cost of goods sold, management fees, or IP royalties, where it may benefit from favorable tax treatment depending on the parent’s jurisdiction (e.g., Hong Kong’s territorial exemption or a UAE free zone).

Transfer pricing methods

The most commonly applied transfer pricing methods in e-commerce distribution arrangements are:

• Transactional Net Margin Method (TNMM) — compares the net profit margin of the tested party (the US entity) against comparable independent companies performing similar functions. This is the most widely used method for limited-risk distributor arrangements.
• Comparable Profits Method (CPM) — the US domestic equivalent of TNMM, commonly applied in IRS examinations. It tests the operating profit of the US entity against a range of comparable companies.
• Resale Price Method (RPM) — starts from the resale price to the end customer and deducts an appropriate gross margin for the distributor. Useful when the distributor does not add significant value to the product.
• Cost Plus Method — determines the transfer price by adding an appropriate markup to the costs incurred by the supplier. More commonly used for intercompany services than for goods distribution.

Documentation requirements

The IRS requires that transfer pricing documentation be contemporaneous, meaning it must be prepared by the time the tax return is filed, not after an audit begins. Adequate documentation includes:

• A functional analysis describing the functions performed, assets used, and risks assumed by each entity
• An economic analysis with a benchmarking study identifying comparable independent companies
• Intercompany agreements signed in advance (not retroactively)
• A clear explanation of the transfer pricing method selected and why it is the most appropriate

Proper documentation is the primary defense against transfer pricing penalties under IRC Section 6662(e), which imposes a 20% penalty on any underpayment resulting from a transfer pricing adjustment, or a 40% penalty in cases of gross valuation misstatement.

6. Substance requirements and the DEMPE framework

A transfer pricing structure is only as strong as the economic substance behind it. Both the OECD Transfer Pricing Guidelines and the IRS emphasize that the allocation of profits must align with where value is actually created, not merely where contracts are signed or entities are incorporated.

What is DEMPE?

The OECD framework uses the acronym DEMPE to describe the key functions related to intangible assets:

• Development — creating and developing the intangible (e.g., product design, brand building)
• Enhancement — improving and updating the intangible over time
• Maintenance — preserving and protecting the value of the intangible
• Protection — legal and practical protection (trademarks, patents, trade secrets)
• Exploitation — commercializing the intangible to generate revenue

The entity that performs the important DEMPE functions, controls the associated risks, and has the financial capacity to bear those risks is entitled to the residual profit, the return above the routine compensation paid to entities performing limited functions.

An entity that merely provides funding or holds legal ownership of intangibles without performing DEMPE functions is entitled only to a risk-adjusted funding return, not the residual profit. This principle is critical: simply registering a trademark in Hong Kong does not entitle the Hong Kong entity to the residual profits if all brand-building, marketing, and strategic decisions are made elsewhere.

What this means in practice

For the transfer pricing structure to be defensible, the foreign parent must genuinely perform the key value-creating functions. This typically means:

• Product development, design, and sourcing decisions are made by the foreign parent
• Marketing strategy and brand direction are controlled by the foreign parent
• The foreign parent has qualified employees (or engaged principals) who exercise decision-making authority
• Contracts with suppliers, manufacturers, and key service providers are entered into by the foreign parent
• The foreign parent bears the inventory risk, market risk, and credit risk

The US entity, in contrast, should perform only the functions consistent with its characterization as a limited-risk distributor: order fulfillment, local customer service, payment collection, and regulatory compliance.

7. The operational case: payment processing and credit advantages

Beyond the tax considerations, there are compelling commercial reasons to establish a US entity for e-commerce operations targeting the American market. These advantages are often overlooked in purely tax-driven structuring discussions, but they can have a material impact on profitability at scale.

Lower payment processing fees

Payment processors charge different rates depending on whether a transaction is classified as domestic or cross-border. For a business selling primarily to US customers:

• US-based merchant (Stripe): 2.9% + USD 0.30 per transaction
• Hong Kong-based merchant (Stripe): 3.4% + HKD 2.35 per transaction, plus an additional 0.5% for international cards and potential currency conversion fees

On Shopify’s Advanced plan, the difference is even more pronounced: US merchants pay 2.4% versus 3.3% for Hong Kong merchants. On USD 1,000,000 in annual revenue, this translates to a saving of USD 5,000 to USD 9,000 per year in processing fees alone.

Higher credit card approval rates

US-domiciled merchants generally achieve significantly higher authorization rates on US-issued credit cards because the transaction is classified as domestic. Cross-border transactions from Hong Kong are subject to additional fraud screening by card issuers, resulting in decline rates that are 15% to 25% higher than domestic transactions.

For a business processing USD 1,000,000 in US card transactions, the difference in approval rates could mean an additional USD 50,000 to USD 100,000 in recovered revenue that would otherwise be lost to declined transactions.

Business credit card cashback

US entities have access to business credit cards offering substantial cashback rewards that are largely unavailable to Hong Kong or UAE-based companies. Programs such as Capital One Spark Cash offer unlimited 2% cashback on all purchases, while category-specific cards can yield 3% to 4% on advertising spend, software subscriptions, and shipping costs.

For a business spending USD 200,000 annually on advertising and operational costs through a US entity, this represents USD 4,000 to USD 8,000 in annual cashback, effectively a direct reduction in operating costs.

Platform and provider compatibility

US entities benefit from easier onboarding and wider acceptance by American payment providers, advertising platforms, and marketplace services. Amazon Seller Central, Meta Ads, and Google Ads all operate more smoothly with US-based entities, US bank accounts, and US employer identification numbers (EINs).

8. IRS enforcement: what happens if you get it wrong

E-commerce sellers who rely on non-compliant structures should not assume they will remain undetected. The IRS has multiple mechanisms to identify foreign sellers operating in the US market.

Platform reporting

Amazon, Shopify, Stripe, and PayPal all file Form 1099-K with the IRS, reporting the gross dollar amount of transactions processed for each seller. The 1099-K includes the seller’s EIN, and the IRS actively matches these forms against filed tax returns. If no return is filed, the IRS computer system will generate automatic notices.

FATCA and international information exchange

The Foreign Account Tax Compliance Act (FATCA) requires foreign financial institutions in partner jurisdictions, including Hong Kong and the UAE, to report information about accounts held by US taxpayers and US-owned entities. The US has FATCA agreements with over 115 jurisdictions, giving the IRS visibility into offshore bank accounts connected to US business operations.

Enforcement timeline

The typical enforcement process escalates over a period of three to four years:

1. Year 1: IRS issues CP2000 correction notices when 1099-K amounts do not match a filed return
2. Year 2: Notices continue with escalating penalties
3. Year 2.5: IRS issues a formal assessment and notice of intent to levy
4. Year 3-4: IRS may issue a jeopardy assessment, garnish bank accounts, and file tax liens

After a tax lien is filed, the IRS has a legal claim against the taxpayer’s property, both real and personal, within the United States. This includes bank accounts, inventory, and receivables from platforms and payment processors.

Penalties

• Failure to file Form 5472: USD 25,000 per form, per year
• Failure to file Form 1120-F: loss of the right to claim deductions and credits
• Transfer pricing penalties: 20% on underpayments resulting from pricing adjustments; 40% for gross valuation misstatements

9. Common e-commerce structures and their tax implications

In practice, we see several recurring structures among cross-border e-commerce entrepreneurs. Each carries its own set of tax consequences, compliance obligations, and operational trade-offs.

UAE holding with US LLC

A UAE free zone entity owns a US single-member LLC. The entrepreneur is typically a tax resident of the UAE (often Dubai), benefiting from 0% personal income tax. The UAE entity may qualify for 0% corporate tax as a Qualifying Free Zone Person, though the standard UAE corporate tax rate is 9% on taxable income exceeding AED 375,000 for non-qualifying income.

The key risk lies on the US side. As a disregarded entity, the LLC’s income flows through to the UAE owner. If the LLC conducts a US trade or business, which is almost always the case for e-commerce sellers with US inventory, US fulfillment, and US customers, the income is treated as ECI and subject to US income tax. The US-UAE tax treaty may reduce the branch profits tax rate, but proper compliance (including timely filing of Form 1120-F) is essential to preserve deductions and treaty benefits.

Electing C-Corporation status for the LLC eliminates the branch profits tax and enables transfer pricing to limit the US taxable base. The residual profit can flow to the UAE entity, where it may benefit from the free zone exemption, provided genuine economic substance is maintained in the UAE.

Hong Kong holding with US LLC

A Hong Kong company owns a US single-member LLC. This structure is popular because Hong Kong’s territorial tax system can exempt offshore-sourced profits, there is no withholding tax on dividends, and no capital gains tax.

However, the absence of a US-Hong Kong tax treaty creates a significant disadvantage: if the LLC remains a disregarded entity, the full 30% branch profits tax applies on top of the regular US income tax, resulting in a combined effective rate of approximately 45%. This makes the C-Corporation election particularly important for Hong Kong-based structures.

With a C-Corp election and proper transfer pricing, the US entity pays 21% corporate tax only on its routine profit margin. No branch profits tax applies because the C-Corp is a US domestic entity. The residual profit flowing to Hong Kong may qualify as offshore-sourced income under Hong Kong’s territorial principle, though compliance with the FSIE regime and adequate substance in Hong Kong are essential.

Individual (natural person) with US LLC only

Some entrepreneurs operate through a US LLC without any foreign holding structure, the LLC is owned directly by the individual. If the individual is a non-US tax resident and the LLC is a single-member entity, the LLC is a disregarded entity and the individual is treated as directly conducting business in the United States.

The individual’s ECI is subject to US federal income tax at graduated rates up to 37%, plus applicable state income taxes. Unlike the corporate scenario, there is no branch profits tax on individuals, but the higher marginal rates and the lack of a transfer pricing mechanism to shift profits make this structure generally less efficient at scale.

For individuals seeking to optimize, the path typically involves incorporating a foreign holding company that owns the US LLC (or electing C-Corp status for the LLC directly). This creates the corporate layer needed for transfer pricing and may enable more favorable treatment of the residual profits in the individual’s jurisdiction of tax residence.

Choosing the right structure

The optimal structure depends on a combination of factors that are unique to each situation:

• Personal tax residency of the entrepreneur, which determines how dividends, capital gains, and worldwide income are taxed at the individual level
• Applicable tax treaties between the US and the holding jurisdiction, affecting BPT rates, withholding rates, and access to dispute resolution mechanisms
• Economic substance in the holding jurisdiction, with genuine operations, employees, and decision-making to support the transfer pricing position
• Scale and growth trajectory of the business, as the operational advantages of a US entity become increasingly material as revenue grows
• Compliance infrastructure per jurisdiction, since each jurisdiction adds filing obligations, documentation requirements, and ongoing costs

10. What should you do next?

If you are operating a cross-border e-commerce business with US sales, the structuring decision is one of the most consequential tax and commercial choices you will make. The key takeaways are:

• A US single-member LLC owned by a foreign entity is not tax-free — the income is taxable to the owner, and the consequences of non-compliance are severe
• Electing C-Corporation status for the US entity eliminates the branch profits tax and creates a clean foundation for transfer pricing
• Transfer pricing, when properly implemented and documented, can legitimately reduce the US taxable base to a routine profit margin of 1% to 5% of revenue
• The foreign parent must have genuine economic substance — real employees, real decision-making, and real functions — to justify retaining the residual profits
• Beyond tax, a US entity offers meaningful commercial advantages: lower payment processing fees, higher approval rates, access to cashback programs, and better platform compatibility

Every situation is different. The right structure depends on your specific facts, including where you live, where your team operates, what products you sell, and how your supply chain is organized. Transfer pricing arrangements must reflect genuine economic reality and be supported by contemporaneous documentation.
