Your marketplace choice now determines whether you need a U.S. entity, what type of entity, and which compliance obligations come with it.
If you are a foreign-owned brand selling in the U.S. in 2026, the rules vary depending on where you sell. Some platforms let you operate from your home country. Others require a U.S. company before you can even apply.
And the moment you form that U.S. entity, a new set of obligations activates that most sellers do not discover until the penalties arrive.
The tariff landscape also shifted dramatically in February 2026. For sellers with the right entity structure, transfer pricing became a legitimate lever to manage that exposure. For sellers with the wrong structure, the risk increased.
The tariff landscape as of March 2026
The Supreme Court changed the math. On February 20, 2026, the Court ruled that IEEPA does not authorize the President to impose tariffs. Every tariff issued under that authority is now invalid.
That includes the reciprocal tariffs that hit nearly every U.S. trading partner, as well as the punitive rates on China that peaked at 145%.
What replaced it? A temporary tariff was signed the same day under separate authority. It is limited to 150 days and expires around late July 2026 unless Congress acts.
It includes exemptions for critical minerals, pharmaceuticals, and goods that comply with existing trade agreements. Section 232 tariffs on steel, aluminum, and autos were not challenged and remain in place.
De minimis is still dead. The exemption that allowed duty-free entry for shipments under $800 was suspended globally in 2025 and remains in effect.
Every shipment entering the U.S. now faces tariff assessment. If your fulfillment model relied on small-parcel direct shipping to avoid duties, that model no longer works.
Why does this matter for entity structure? If your U.S. entity purchases inventory from your foreign parent company, the price you set on that intercompany transaction determines how much of the value is subject to U.S. tariffs and how much falls under U.S. taxable income.
Transfer pricing is both a compliance requirement and a tariff strategy. Get the structure right, and it works in your favor. Get it wrong, and you have no defensible position when customs or the IRS asks questions.
Which platforms require a U.S. entity
Amazon. A U.S. entity is optional. Most foreign-owned brands sell on Amazon.com through their home-country entity, using a foreign bank account and foreign address.
But there is a trade-off. When a buyer clicks “Sold By” on your product page, they see your entity name and address. A foreign company and foreign address cost you trust and conversions.
If you want to appear as a U.S.-based seller, you need a U.S. entity. And Amazon’s verification process requires proof of actual operational presence, not a registered agent address.
TikTok Shop. A U.S. entity is required for sellers from most countries. You cannot onboard without one.
The verification process checks your EIN, your W-9 classification, your business address, your U.S. authorized representative, and your identity documents. Foreign-owned single-member LLCs face a specific challenge with the W-9 posture that is the single most common verification failure we see.
TikTok Shop also enforces a two-appeal limit. Fail twice, and your entity is permanently blocked.
Walmart Marketplace. A U.S. entity and U.S. tax ID are required for sellers from most countries. The verification process differs from that of TikTok Shop and Amazon. Sellers who were verified on Amazon often assume Walmart will be automatic. It is not. Different platform, different checks, different failure points.
Shopify and DTC. Shopify Payments and Stripe require U.S. entity verification for U.S. payment processing.
KYC checks cross-reference your entity formation documents, EIN, bank account, and identity. A clean compliance record passes quickly. An entity with address mismatches or missing filings stalls.
What U.S. entity triggers
The day you form a U.S. LLC owned by a foreign person or foreign company, compliance obligations activate whether you know about them or not.
Annual tax filings with automatic penalties for each missed year. W-9 classification requirements that determine how platforms, banks, and the IRS view your entity. Transfer pricing documentation for every intercompany transaction between your U.S. entity and your foreign parent.
Potential state-level obligations depending on where you store inventory and where you sell. And there is no statute of limitations on unfiled returns, which means the exposure is cumulative and permanent until resolved.
Most sellers who formed a U.S. entity two or three years ago are only now discovering what was missed. The penalties are real, the exposure is cumulative, and the cost of remediation grows every year you wait.
The cross-platform verification problem
Every platform runs its own verification process independently. They each cross-reference different data points. But the failure pattern is the same everywhere.
A seller forms a Wyoming LLC with a registered agent address, uses that address for their EIN, opens a bank account with a different address, and completes marketplace registration with a third address. That is three address mismatches across four systems.
Every verification process on every platform catches this. On Amazon, it triggers document requests and 30-to-60-day holds. On TikTok Shop, it burns one of your two appeals. On Walmart, it stalls onboarding entirely.
Marketplaces are now required to verify seller identity and disclose business information to buyers. Your entity name, address, and contact information are visible to every customer.
If your structure does not support this disclosure cleanly, you have a credibility problem on top of a verification problem.
The fix is not a better virtual address. The fix is a coherent entity structure where every document, every address, and every filing tells the same story across every platform.
“Buy American” is a buyer behavior
On platforms where your entity information is visible to buyers, a U.S. entity changes how buyers perceive your brand.
American consumers are checking seller profiles more than ever. When they see a foreign name, a foreign address, or an entity they cannot verify, conversion drops. This pattern holds across categories, especially in health, beauty, supplements, electronics, and anything where trust matters.
A U.S. entity with a real U.S. address on the seller profile tells the buyer you are invested in the market.
But the entity has to be real. A formation-mill LLC with a registered agent address, no operating agreement, and no compliance records does not create credibility. It creates risk.
Find out where your entity actually stands
If you are a foreign-owned brand selling on U.S. marketplaces or planning to, the first step is understanding where your entity stands today. Not where you think it stands. Where it actually stands.
