You can build a profitable U.S. e-commerce operation from anywhere in the world without living in the United States—millions already do it.

Understanding taxes as a non-resident

Non-U.S. sellers often believe:

“If I don’t live in the U.S., I don’t pay taxes.”

Incorrect.

The real rule is:

✅ If you have taxable U.S. income, you pay taxes.
❗ If not, you may pay $0 federal tax.

Let’s break down the 8 must-know tax rules.

Tax Rule #1: Your Business Structure Affects Tax Obligations

LLC vs. C-Corporation

Most non-residents choose LLC (Limited Liability Company). Why?

It protects your personal assets.
It avoids double taxation.
If income is not “effectively connected” to the U.S., the LLC may pay $0 federal tax.

A C-Corporation, often in Delaware, is common for startups seeking investors, but:

It pays corporate tax + dividend tax (double taxation).

Where to register—Delaware, Wyoming, or Florida?

✅ Delaware — Investor-friendly, best for startups.
✅ Wyoming — No corporate income tax; very private.
✅ Florida — Good for sellers needing physical fulfillment centers.

Tax Rule #2: EIN (Employer Identification Number) Is Mandatory

EIN for tax filing and payment gateways

Without an EIN, you can’t:

Pay taxes
File taxes
Accept payments legally

Banking and payment gateways: Stripe & PayPal

Most payment gateways (Stripe, PayPal) require:

✅ EIN
✅ U.S. business address
✅ U.S. bank account

Tax Rule #3: Sales Tax Applies by State, Not Federal Government

Sales tax is not federal. Each state has its own rules.

What triggers sales tax (Nexus)?

“Nexus” = a connection to a state.

Two ways nexus is triggered:

Type of Nexus	What It Means
Physical nexus	Warehouses, employees, U.S. inventory.
Economic nexus	Selling more than X amount in a state.

Shopify, Amazon, and other e-commerce marketplaces

If you sell through marketplaces:

Amazon collects and pays sales tax for you.
Shopify requires app integrations.

Tax Rule #4: Federal Taxes Depend on “Effectively Connected Income (ECI)”

If your business has no ECI, you may owe $0 federal tax.

Example:

✅ You operate from outside the U.S.
✅ You don’t have warehouses, offices, or employees in the U.S.

→ You may legally pay zero federal tax.
