Concept
U.S. tax planning for Americans abroad is not a secrecy exercise. It is a legal design process: fix U.S. status, report worldwide income, choose the right exclusion or credit, classify entities correctly, avoid toxic investments, document foreign taxes and keep enough evidence to survive bank and IRS review.
The tools below are described at a high level. The right answer depends on facts and should be modeled by a U.S. international tax CPA or tax attorney before, not after, the transaction.
Income tools
For earned income, the first choice is between two reliefs.
Foreign earned income exclusion
The foreign earned income exclusion can help where income is earned abroad and the taxpayer meets the tax-home and presence tests. It does not eliminate every U.S. tax item and does not remove self-employment tax.
Foreign tax credit
The foreign tax credit often works better where the foreign country has high income tax. Baskets, sourcing, timing and carryovers all matter, and FEIE-excluded income cannot also generate a credit.
For self-employed founders and consultants, review the IRS rules on self-employment tax for businesses abroad and totalization agreements. Social security coordination through a totalization agreement can be as important as the income tax answer, because FEIE does not switch off self-employment tax.
Entity tools
Entity planning starts with classification. Form 8832 — the check-the-box election — can set the classification for an eligible entity, but the consequences may include deemed transactions. A foreign company can trigger U.S. CFC rules, while foreign partnerships, disregarded entities and transfers can trigger foreign entity forms.
Where a controlled foreign corporation is in play, the section 951A regime drives the planning — taxed as GILTI for years through 2025 and renamed net CFC tested income (NCTI) from 2026. Common responses are a section 962 election (to be taxed at corporate rates with a credit), the high-tax exception, and in some cases a U.S. C-corp blocker that holds the foreign company so the regime lands inside a corporate structure rather than on the individual. Each of these is a trade-off across current tax, future distributions and exit, not a default.
Investment tools
The cleanest PFIC planning is avoidance before purchase. Many non-U.S. mutual funds and ETFs can create PFIC and Form 8621 work. If a U.S. person already holds PFIC assets, the review should consider available elections, historic data and whether the fund provides the information needed for a qualified electing fund election.
Crypto, private funds, insurance wrappers and foreign pensions need separate classification. Do not assume that local tax deferral is respected by the United States.
Trust and family tools
Trusts can support governance, succession and asset segregation, but a U.S. person needs a trust status review before funding or distributions, and a domestic U.S. trust is often cleaner than a foreign one. The IRS pages for Form 3520 and Form 3520-A show why a private family arrangement becomes a formal U.S. reporting obligation; the detail sits in foreign trusts and Form 3520.
Pre-immigration planning — including basis step-up and entity or trust restructuring — should happen before a green card, substantial presence or move to the United States, because most of it cannot be done once the person is inside the system. Expatriation planning should happen only after the five-year tax history, balance sheet, covered-expatriate status and immigration consequences have been reviewed.
Checklist
- Confirm U.S. person status before choosing any planning tool.
- Model FEIE versus the foreign tax credit by year and income category.
- Check self-employment tax and totalization before setting compensation.
- Classify every foreign entity and document each Form 8832 election.
- Model section 951A, a section 962 election and the high-tax exception before holding a CFC.
- Screen funds, ETFs and insurance wrappers for PFIC risk before purchase.
- Review trusts before funding, adding U.S. beneficiaries or making distributions.
- Run pre-immigration basis planning before a green card or substantial presence.
- Keep a written memo for each major election and non-election.
Common mistakes
- Treating FEIE as a complete exit from U.S. tax.
- Claiming a foreign tax credit without matching income category, timing and source.
- Forming a foreign company before checking CFC, section 951A and Form 5471 consequences.
- Buying non-U.S. funds through a private bank without PFIC review.
- Using a foreign trust to hold U.S.-connected family assets without Forms 3520 and 3520-A analysis.
- Missing pre-immigration basis planning until after the move.
- Planning expatriation before cleaning up five years of filings.
Advisor trigger
Use professional advice before any relocation, green card, equity grant, foreign company, trust, fund portfolio, crypto structure, large gift, inheritance, sale of a business or citizenship decision.
Q&A
FEIE or the foreign tax credit — which is better
It depends on the foreign tax rate and the income type. FEIE tends to fit low-tax or no-tax countries; the foreign tax credit tends to fit high-tax countries and can carry over. They cannot both be claimed on the same income, and FEIE does not remove self-employment tax, which is where a totalization agreement matters.
What does a check-the-box election on Form 8832 do
It sets the U.S. tax classification of an eligible foreign entity — corporation, partnership or disregarded entity. It can simplify reporting or change the CFC and credit position, but the election itself can create deemed transactions, so it should be modeled before filing.
How does section 951A affect a U.S. owner of a foreign company
A controlled foreign corporation can bring the section 951A regime — taxed as GILTI for years through 2025 and renamed net CFC tested income (NCTI) from 2026. A section 962 election, the high-tax exception or a U.S. C-corp blocker can change how that income is taxed, each with its own trade-offs.
Why is a foreign ETF a planning problem
A non-U.S. fund is usually a PFIC, and the default PFIC regime is punitive. The cleanest answer is avoidance before purchase; once held, the review turns to elections and whether the fund supplies qualified-electing-fund data. Form 8621 reporting applies either way.
When should pre-immigration planning happen
Before the green card, substantial presence or move. Basis step-up and entity or trust restructuring are largely unavailable once a person is inside the U.S. system, so the window closes on the date residency starts.
