For U.S. citizens or green‑card holders, simply registering an offshore company does not eliminate U.S. tax liability. The tax treatment depends on residency status, where the work is performed, and how the business is structured.
Tax residency and “tax home”
- A U.S. person (citizen or green‑card holder) is taxed on worldwide income regardless of physical location.
- To reduce U.S. taxes you must establish a tax home outside the United States—either by spending the majority of the year abroad (typically > 6 months) or by obtaining a bona‑fide residence through investment, long‑term lease, or other qualifying ties.
- Short, intermittent trips back to the home country no longer suffice; most jurisdictions now require a substantial, continuous presence to be considered a non‑resident for tax purposes.
Offshore entities are not a tax shield
- Many countries have entities called “LLC” or “limited company,” but they are not equivalent to a U.S. LLC and do not automatically provide tax exemption for U.S. owners.
- A foreign corporation owned by a U.S. person is treated as a Controlled Foreign Corporation (CFC). Income may be subject to U.S. tax under Subpart F or the Global Intangible Low‑Tax Income (GILTI) rules unless specific exceptions apply.
- The “remittance basis” (keeping earnings abroad and never bringing them into the U.S.) does not prevent U.S. taxation for U.S. persons.
Practical ways to lower U.S. tax on e‑commerce income
| Tool | How it works | Typical impact |
|---|---|---|
| Foreign Earned Income Exclusion (FEIE) | Allows up to $108,700 (2021) of earned income to be excluded if you meet the bona‑fide residence or physical presence test. | Reduces taxable salary; does not apply to corporate profits. |
| Foreign Tax Credit | Offsets U.S. tax with foreign income taxes paid on the same income. | Useful when the foreign jurisdiction taxes the same earnings. |
| Foreign corporation structure | Operate the e‑commerce business through a non‑U.S. corporation; pay yourself a salary (subject to FEIE) and retain profits abroad. | Can lower or eliminate U.S. income tax and reduce Social Security/Medicare liabilities on retained earnings. |
| Puerto Rico tax incentives | Residents who qualify for the Export Services Act can enjoy a reduced income‑tax rate (as low as 4 %). | Viable if you can spend the required time in Puerto Rico and shift qualifying activities there. |
E‑commerce‑specific considerations
- Permanent establishment – If you store inventory, fulfill orders, or maintain a warehouse in the U.S., the foreign corporation may be deemed to have a U.S. permanent establishment, triggering U.S. tax on related profits.
- Transfer pricing – Transactions between your foreign entity and any U.S. related party must be at arm’s‑length prices; otherwise the IRS may reallocate income.
- Credit‑card processing – Many low‑tax jurisdictions have limited access to major payment processors, which can complicate merchant account setup. A multi‑jurisdiction structure (e.g., foreign entity for operations, separate entity in a processor‑friendly country) may be required.
- Physical product vs. digital services – Shipping goods from the U.S. or using U.S. fulfillment centers creates additional nexus risks; SaaS or consulting businesses face fewer physical‑presence issues.
Capital‑gains planning
- When selling an e‑commerce business, U.S. citizens are subject to capital‑gains tax on the worldwide sale.
- Relocating to Puerto Rico before a sale can allow the gain to be taxed at the island’s lower rates, provided the sale qualifies as an “export service.”
- Delaying the sale may increase exposure to potential U.S. capital‑gains rate hikes.
Bottom line
- You cannot avoid U.S. tax simply by forming an offshore LLC.
- Establish a genuine tax home abroad, use the FEIE for personal salary, and consider a foreign corporation to retain profits.
- Evaluate nexus, permanent‑establishment, and transfer‑pricing risks tied to inventory and fulfillment.
- Puerto Rico offers a competitive alternative for U.S. persons who can meet its residency requirements.
Each of these strategies carries compliance requirements and potential pitfalls; professional tax advice is essential before implementing any structure.
