U.S. Taxes for Non-Resident Amazon Sellers With an LLC

TL;DR

A non-resident Amazon seller with a U.S. LLC is really dealing with three separate topics: ① the mandatory Form 5472 information filing (applies to virtually every foreign-owned LLC, even with zero sales), ② possible U.S. income tax (depends on whether the activity is “effectively connected” — a judgment call), and ③ sales tax (mostly handled by Amazon). Confusing the three is the most expensive mistake sellers make.

Which taxes does a non-resident Amazon seller face?

Layer 1: Form 5472 — the one almost nobody escapes

If a non-U.S. person owns the LLC, the LLC must file Form 5472 with a pro forma Form 1120 for every year it had a reportable transaction. Registering the company and putting money in already count — so the obligation usually starts before your first sale.

This is an information return, not a tax bill. But skipping it is what generates the horror stories: the penalty starts at $25,000 per return. Start with who must file Form 5472 and why zero income doesn’t exempt you.

Layer 2: income tax — the “it depends” layer

Whether a non-resident seller owes U.S. income tax turns on whether the business has effectively connected income (ECI) — income from a U.S. trade or business. For FBA sellers this is a genuinely debated, fact-specific question involving where your activity, inventory, and people are.

Two honest statements about it:

• No blanket answer is trustworthy. Anyone who tells every seller “you never owe U.S. income tax” or “you always do” is skipping the analysis. See our plain-English look at the ECI question.
• The 5472 obligation exists either way. Even sellers who conclude they owe no income tax still owe the information filing.

Layer 3: sales tax — mostly Amazon’s job now

Under marketplace facilitator laws, Amazon itself collects and remits sales tax on marketplace orders in essentially all U.S. states. Most small foreign sellers do not remit sales tax themselves for pure-Amazon sales — though selling off-Amazon (your own Shopify checkout) can create separate obligations.

Sales tax is not income tax, and paying it (or Amazon handling it) does not satisfy Form 5472 or any federal filing.

Selling software instead of products?

The same three-layer map applies to SaaS and digital services — same mandatory 5472, same ECI framework, plus a state-by-state SaaS sales-tax wrinkle. The SaaS founder’s version of this guide is here.

What this is NOT saying

• Not “sellers owe no U.S. tax.” The income-tax layer is a judgment; the information filing is near-universal.
• Not “Amazon handles your taxes.” Amazon handles most sales tax on marketplace orders. Nothing else.
• Not “no sales = no filings.” Formation + capital already trigger Form 5472.

What should a first-year seller actually do?

1. Get the EIN — needed for banking, Amazon, and filings (no SSN required).
2. Keep the LLC’s money separate and keep bank records — they are the source data for Form 5472.
3. Calendar April 15 (5472 due; extendable to Oct 15) — see the deadline calendar.
4. File Form 5472 every year, dormant or busy.
5. Get the ECI question assessed once by a licensed preparer instead of guessing annually.
