Concept
For Americans abroad, U.S. tax planning is a legal design process, not a secrecy exercise: fix U.S. person 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.
These tools interact, so they cannot be chosen one at a time: a residence election changes the credit math, an entity election changes the reporting, and an investment choice changes both. Model the whole set together against real facts, before the transaction rather than on the return.
Almost every tool here only works if it is chosen before the event — before the foreign company is formed, before the fund is bought, before the green card, before the move. Run the model first; planning after the transaction is usually cleanup, and cleanup is more expensive.
Income tools
For earned income, the first choice is between two reliefs.
Foreign earned income exclusion
The foreign earned income exclusion (up to $132,900 for 2026, $130,000 for 2025) 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.
The 2025 Act: individual provisions
The One Big Beautiful Bill Act (P.L. 119-21, signed 4 July 2025) rewrote more than the corporate contour. Its individual half changes the arithmetic of the return from 2026, and for an American abroad it shares one feature: two of the new thresholds run off modified adjusted gross income, which adds back income excluded under § 911. A claimed FEIE lowers the tax and at the same time leaves those reliefs out of reach.
| Provision | Substance | Horizon |
|---|---|---|
| State and local tax deduction, § 164(b)(6)–(7) | Cap of $40,000 for 2025 and $40,400 for 2026, then 101% of the prior year's figure through 2029. Reduced by 30% of MAGI above $500,000 for 2025 and $505,000 for 2026, with a $10,000 floor | 2025–2029; flat $10,000 from 2030 |
| Charitable floor, § 170(b)(1)(I) | Itemised charitable contributions are allowed only above 0.5% of the contribution base. Non-itemisers gained a permanent $1,000 deduction ($2,000 on a joint return) under § 170(p), cash only and not to a donor advised fund | from 2026 |
| Limitation on itemised deductions, § 68 | Deductions are reduced by 2/37 of the lesser of the deductions themselves and taxable income above the start of the 37% bracket. In the top bracket that is 35 cents of relief per dollar deducted | from 2026 |
| Opportunity Zones, § 1400Z-2 | Made permanent. For amounts invested in a qualified fund after 31 December 2026, basis steps up by 10% at five years and by 30% in a qualified rural opportunity fund | from 2027 |
| Senior deduction, § 151(d)(5)(C) | $6,000 per qualified individual aged 65 or over, reduced by 6% of MAGI above $75,000 ($150,000 on a joint return) | through 2028 |
| Trump accounts, § 530A | A child account taxed as an IRA: contributions up to $5,000 a year, none accepted until twelve months after enactment, distributions from the year the beneficiary turns 18. § 6434 adds a $1,000 federal payment for a U.S.-citizen child born from 2025 through 2028 | — |
The rate contour itself is unchanged. The 37% top rate survives and starts at $640,600 for single filers and $768,700 for married filing jointly in 2026; the alternative minimum tax exemption is $90,100 and $140,200, phasing out from $500,000 and $1,000,000.
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 through 2025 and renamed net CFC tested income (NCTI) for tax years beginning after 2025. Under OBBBA the base hardens — the 10% QBAI routine-return carve-out is gone, the section 250 deduction falls from 50% to 40% (an effective corporate rate near 12.6%), and the deemed-paid foreign tax credit rises from 80% to 90%. Common responses are a section 962 election (taxed at corporate rates with that credit), the high-tax exception and treaty positions, all of which need numbers, not labels.
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. Filing is not automatic: Treas. Reg. § 1.1298-1(c)(2) lifts Form 8621 for a section 1291 fund where the aggregate value of all PFIC stock on the last day of the year is $25,000 or less ($50,000 on a joint return), there was no excess distribution that year and no QEF election is in force. The regimes and the limits of that threshold sit in PFIC and Form 8621.
Crypto, private funds, insurance wrappers and foreign pensions need separate classification, and local tax deferral is not respected by the United States on its own; even a Roth carried abroad depends on a treaty to keep its shelter.
For digital assets the decisive change is what the IRS sees without a return. Custodial brokers report on Form 1099-DA: gross proceeds for transactions from 1 January 2025, and basis for digital assets acquired after 2025, which means from tax year 2026. The parallel rule for non-custodial DeFi front ends did not survive to that point: the Congressional Review Act resolution was signed on 10 April 2025 (P.L. 119-5) and the rule itself was removed from the CFR by a Federal Register publication on 11 July 2025. What travels onward through the international channels sits in Crypto tax reporting.
Insurance wrappers now carry a distinct regulatory risk. The Protecting Proper Life Insurance from Abuse Act was introduced in the Senate on 13 April 2026. It creates the category of an applicable private placement contract and leaves outside it only products whose segregated account serves at least twenty-five contracts on a strictly pro rata basis; a holder of an applicable contract loses tax-deferred inside buildup and is taxed currently on the account's income. The stated reach extends to policies already issued, with a 180-day transition. The bill has been introduced and not enacted, and its further progress is unconfirmed — it changes the risk profile of the product even so.
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.
The transfer-tax figures that the whole family layer runs off were fixed for the long term by the 2025 Act. The basic exclusion amount is $15,000,000 per person for 2026, indexed from 2027, and the sunset that used to fall at the end of 2025 is gone. The annual exclusion is $19,000, and $194,000 for a non-citizen spouse. The Form 706-NA filing threshold for a non-resident non-citizen decedent is unchanged at $60,000 of U.S.-situs property in the gross estate.
Pre-immigration planning — including basis step-up and entity or trust restructuring — should happen before a green card, substantial presence or a move to the United States, because most of it cannot be undone afterwards.
Leaving the system has a tail that reframes the planning question. A gift or bequest from a covered expatriate is taxed to the U.S. recipient under § 2801, at the highest estate tax rate for the year on everything above the same $19,000 annual exclusion, reported on Form 708. The final regulations, TD 10027, were published and took effect on 14 January 2025. The regime is set out in Section 2801: gifts and bequests from covered expatriates; the covered-expatriate thresholds sit in Expatriation and U.S. exit tax.
Reporting tools
Reporting is its own layer, separate from the tax computation. A U.S. person abroad usually files FinCEN Form 114 — the FBAR — once foreign accounts cross $10,000 in aggregate at any point in the year, and Form 8938 with the return once the higher FATCA thresholds are met. The two overlap, but neither replaces the other, and entity or trust positions pull in Forms 5471, 8865 and 8858 and 3520 and 3520-A on top.
When each tool is chosen
Every tool above shares one property: a moment before which it is available and after which it is not. The table sets each decision against that moment.
| Decision | Timing |
|---|---|
| U.S. person status | Fixed first: it decides whether any of the rest applies |
| FEIE or foreign tax credit | Modelled by year and income category |
| Self-employment tax and totalization | Before compensation is set |
| Classification of each foreign entity | At formation; every Form 8832 election documented |
| Section 951A, section 962 election, high-tax exception | Before a CFC is held |
| PFIC screen of funds, ETFs, insurance wrappers | Before purchase |
| Trust review | Before funding, before adding U.S. beneficiaries, before distributions |
| Pre-immigration basis planning | Before a green card or substantial presence |
| FBAR and Form 8938 | With the year's filings, reconciled against the 5471, 8865 and 3520 series |
| Gifts and succession structure ahead of expatriation | Before the expatriation date: afterwards the transfer lands on the recipient under § 2801 |
| Written memo | At each major election and each deliberate non-election |
Each row of that table read backwards gives a standard mistake: the decision was taken after its moment. That alone does not lose the position — what makes it contestable is how the decision was papered.
What reads as artificial
None of the tools above works as a formality; what is tested is whether the stated structure matches the facts on the ground. A Form 8832 election fitted to a transaction that has already happened, or papered after the fact, reads as retrospective tailoring. A classification that diverges from who actually takes the decisions and where is exposed in the same way: check-the-box sets the tax regime and leaves the management facts untouched. The same goes for a trust whose instructions in practice come from the settlor, and for a valuation of a private holding produced after the event and without an independent opinion.
A defensible position is built from ordinary things: documents dated before the event, an election filed on time and on the form prescribed for it, a computation and a memorandum written when the decision was taken, and no divergence between what was told to the bank, the local tax authority and the IRS. A written memo at each major election — and at each deliberate non-election — belongs to the same evidentiary layer as the forms.
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.
- Reporting income correctly but missing the FBAR, Form 8938 and the 5471, 8865 or 3520 returns.

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 does not follow in every case: a section 1291 fund carries a de minimis threshold — $25,000 of aggregate PFIC stock at year end ($50,000 on a joint return), with no excess distribution and no QEF election. The threshold removes the filing and leaves the regime itself in place.
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.
