If your company sells, raises funds, invoices customers or holds inventory across China, Hong Kong and the United States, US company formation for non-US residents / LLC vs C-Corp for Amazon sellers is not a side issue. The practical question is where a registration, tax return, report or supporting file becomes expected, and which entity owns that duty. EasyTax turns that question into a working compliance plan: we review the facts, separate marketplace activity from direct sales, map the filings, and keep the Chinese-speaking management team clear on what must be done before money, goods or platform data move again.
Before forming the US company
Before formation, establish the US entity’s role in the transaction. The platform account, receiving account, invoice party, warehouse arrangement and tax records should point to the same business story. A US incorporation document alone does not resolve a mismatch with the underlying sales, inventory or ownership records.
The formation file records the entities involved, the trading flow, the US company’s intended function, the responsible person and the documents still needed. Rates, thresholds, filing dates, penalties and formal counts are checked against the current rule and the client file before they are used in implementation.
How we prepare for formation
- Formation review — identify the selling model, ownership chain, platform accounts, bank flows, warehouses and contract path that the US company will support.
- Formation decision path — identify which registrations, tax accounts, reports or supporting schedules are relevant to entity selection, state comparison, registered agent coordination and post-formation tax setup.
- Record preparation — organise platform exports, invoices, bank statements, contracts and bookkeeping so the US company’s role can be supported after formation.
- Post-formation coordination — align internal finance and external parties on the documents, signatures, payment instructions and evidence needed after the company is formed.
- Entity lifecycle review — revisit the arrangement when a new marketplace, state, warehouse, customer country or ownership change affects the US company’s role.
What the formation file contains
The working file sets out the proposed US company structure, the supporting records, the action owner and the next registration or filing step. It connects the formation decision with the operating facts: who sells, invoices, receives funds, owns the platform account and signs the required documents.
For marketplace sellers, platform reports and settlement records help establish which entity is trading. For service businesses, contracts, source of income and management arrangements matter. For holding structures, the ownership chain and reporting duties should be clear before the US company is put into use.
A cross-border view of US formation
EasyTax is an Amazon SPN certified service provider and a TikTok TSP certified service provider, working across the US, Hong Kong and mainland China. US formation for a cross-border seller needs to fit the platform, banking, accounting and company records already used by the business.
This is particularly relevant where the founder is outside the United States, the holding company is in Hong Kong, the operating team is in mainland China and sales run through several platforms. The US company should be assessed alongside those existing entities and records, rather than as a standalone registration.
Questions non-US founders ask before US formation
When should we review US company formation for non-US residents / LLC vs C-Corp for Amazon sellers? Review it before a new entity starts trading, before inventory or funds move through a new country, and whenever platform sales or direct contracts materially change. If a rule contains a sales threshold, filing date or ownership count, EasyTax confirms the live figure for the exact state, country or authority before implementation.
Can a foreign owner form and maintain the company without a local office? Often yes, subject to the filing type, signature method, identity documents, tax account access and any requirement for a registered agent, secretary, tax representative or preparer. The required company and business records should be prepared before the process begins.
What documents should be prepared first? Begin with ownership records, platform reports, bank statements, contracts, invoices, bookkeeping exports and any existing company papers. These help establish how the US company will relate to legal ownership, sales activity and cash movement.
