International tax planning for US expats: strategies, structures, and compliance in 2026
International tax planning legally structures global income, assets, and business activity to manage worldwide tax while meeting US and foreign rules. For 2025 returns filed in 2026, two core tools are Form 2555 for the Foreign Earned Income Exclusion and Form 1116 for the Foreign Tax Credit.
US citizens and Green Card holders generally remain subject to US filing rules on worldwide income while abroad. TFX’s guide to citizenship-based taxation explains why residence abroad does not, by itself, end those federal obligations, so an international tax plan should start with required reporting before comparing lawful ways to reduce double taxation.
International tax planning for individuals is different from hiding income or assets offshore. The work is to identify exclusions, credits, treaty provisions, entity rules, and timing choices that the law permits, then document each position and file the required forms, which can include FBAR, Form 8938, Form 5471, or Form 8621.
International tax planning is the legal process of structuring your global income, assets, and business activities to minimize worldwide tax liability while remaining fully compliant with US and foreign tax laws. The IRS Foreign Earned Income Exclusion rules show one statutory route, but eligibility and the best combination of rules depend on your income type, country, and filing facts.
What should you look for among top firms for international cross-border tax planning? Look for international tax consulting that connects US forms, foreign tax, treaty rules, and implementation rather than treating each country in isolation. Expatriate tax services should also explain what each filing position changes.
Why US citizens and expats face unique international tax challenges
US citizens and resident aliens report worldwide income on a US return even after moving abroad, and foreign account reporting can apply separately. For calendar year 2025, an FBAR is required when aggregate foreign accounts exceed $10,000 at any time, with a 2026 filing cycle distinct from Form 1040.
That overlap creates three recurring risks: paying tax to 2 countries on the same income, missing a foreign-information return, and reporting foreign income in the wrong US tax year. See TFX’s guide to reporting the timing of foreign income and foreign taxes when foreign tax years, pay dates, or accrual methods do not line up with the US calendar year; these timing issues are part of US expat tax obligations.
FBAR is a separate Bank Secrecy Act filing, not an attachment to Form 1040. The IRS FBAR filing rules apply based on financial interest or signature authority and the $10,000 aggregate threshold, while FATCA Form 8938 uses different thresholds and is filed with the federal income tax return.
Unlike most countries, the US requires citizens and Green Card holders to file US tax returns and report global income when the applicable filing rules are met, even after years abroad. International tax planning matters because the income-tax return, FBAR, FATCA, and entity-reporting systems can overlap without using the same forms, thresholds, or filing destinations.
Core international tax planning strategies for individuals
Five international tax planning strategies form the starting toolkit for an individual abroad in 2026: Form 2555, Form 1116, treaty relief, residency choices, and income timing. International tax planning for individuals must test wages, self-employment income, investments, and business earnings separately because each category can respond differently to those tools.
The following 5 strategies address the most common sources of double taxation and timing mismatch for US taxpayers abroad:
- Foreign Earned Income Exclusion – Form 2555. For 2025, a qualifying person can exclude up to $130,000 of foreign earned income; for tax year 2026, the ceiling is $132,900. The exclusion applies to earned income, not dividends, pensions, or capital gains.
- Foreign Tax Credit – Form 1116. Eligible foreign income taxes can reduce US income tax on the same foreign-source income, subject to the separate-category limitation. This approach can preserve excess credits for later years where carryovers are allowed.
- Tax treaty benefits. A treaty can change source, withholding, pension, or residence outcomes, but the result depends on the specific treaty article and the treaty’s saving clause. Treaty-based return positions can also trigger Form 8833 disclosure.
- Tax residency planning. Foreign residence may affect the bona fide residence test, treaty tie-breakers for eligible dual residents, and host-country exposure. It does not end US citizenship-based filing by itself.
- Timing income and deductions. Matching when income is recognized with when foreign tax is paid or accrued can affect the Form 1116 limitation and whether a credit is usable in the current year.
TFX’s FEIE versus Foreign Tax Credit comparison compares the 2 methods when the same foreign earnings and taxes are tested.
Choosing between the Foreign Earned Income Exclusion and the Foreign Tax Credit is often one of the highest-impact choices in an expat tax plan. The IRS guidance on choosing the FEIE explains how the election is made and when it can be revoked.
Foreign Earned Income Exclusion: the most widely used expat tax strategy
For tax year 2025, the Foreign Earned Income Exclusion can exclude up to $130,000 of qualifying foreign earned income on Form 2555; the 2026 limit is $132,900. Eligibility also requires a foreign tax home and either the bona fide residence test or the 330-full-day physical presence test.
The TFX guide to the Foreign Earned Income Exclusion covers the income types and filing mechanics. Wages, salary, and qualifying self-employment income can be foreign earned income when the services are performed abroad, but investment income, pensions, and most rental income do not become excludable merely because the taxpayer lives overseas.
The IRS bona fide residence test requires an uninterrupted period that includes an entire tax year, while the physical presence test measures 330 full days in foreign countries during any 12 consecutive months. A person can satisfy one test without satisfying the other, and brief trips do not automatically determine the result.
The FEIE is claimed on Form 2555 and can reduce US income tax on qualifying wages and self-employment income earned abroad, up to the applicable annual limit. It does not reduce self-employment tax by itself, so a freelancer’s income-tax result and Social Security tax result must be analyzed separately.
Foreign Tax Credit: eliminating double taxation on foreign-source income
Form 1116 can give an individual a dollar-for-dollar US credit for qualifying foreign income tax, subject to the limitation for the relevant income category. For 2025 returns filed in 2026, excess eligible credits generally carry back 1 year and forward 10 years, with category-specific exceptions.
See TFX’s Form 1116 Foreign Tax Credit guide for the separate baskets and limitation calculation. In a higher-tax country, the credit can reduce US income tax on the same foreign-source income to $0 when the available credit and limitation are large enough, but that outcome is a calculation, not an automatic rule.
The IRS FEIE forms guidance also shows that Form 2555 and Form 1116 interact. Taxpayers cannot claim a foreign tax credit for taxes allocable to income excluded under the FEIE, so the return must separate excluded income, taxable foreign-source income, and the foreign taxes tied to each.
For expats in higher-tax countries, the Foreign Tax Credit can reduce or eliminate residual US income tax while preserving eligible excess credits for future years. It does not, by itself, remove US self-employment tax, which is why self-employed taxpayers should analyze income tax and social insurance separately.
International tax planning strategies for corporations and business owners
International tax planning for corporations and owner-managed foreign businesses changed for tax years beginning after December 31, 2025: section 951A now uses net CFC tested income, or NCTI, instead of the former GILTI computation. CFC, Subpart F, section 962, transfer pricing, and entity selection still require separate analysis and forms.
The following 5 areas drive most US federal tax and reporting decisions for a US owner of a foreign company:
- Controlled foreign corporation rules and Subpart F income. A U.S. shareholder generally means a U.S. person owning at least 10% of vote or value; a foreign corporation is generally a CFC when U.S. shareholders own more than 50%, applying attribution rules. Form 5471 can follow.
- Section 951A NCTI, formerly GILTI. For taxable years beginning after December 31, 2025, the revised section 951A calculation removes the old QBAI-based routine return from the statutory computation and uses net CFC tested income.
- Section 962 election. An individual U.S. shareholder can elect corporate-style treatment for certain section 951 and 951A inclusions, including section 960 deemed-paid credit mechanics. Model later distributions before choosing the election.
- Transfer pricing compliance. IRC section 482 requires controlled parties to price intercompany transactions on an arm’s-length basis. Transfer pricing regulations matter even when the business is privately held rather than a public multinational.
- Entity selection. A branch, CFC, disregarded entity, or partnership can produce different current inclusions, foreign tax credit positions, information returns, and repatriation results.
TFX’s section 962 election overview explains owner-level mechanics for an individual U.S. shareholder. International corporate tax planning should model both the inclusion year and later distributions before an election is chosen.
Owning 10% of a foreign corporation can make a US person a U.S. shareholder, but CFC status generally requires more than 50% US-shareholder ownership of vote or value. The IRS Form 5471 filing guidance is the starting point for filing categories and ownership definitions.
Choosing the right business structure for international operations
Four common international tax planning structures lead to different US tax and filing results: a foreign branch, foreign subsidiary or CFC, foreign disregarded entity, and foreign partnership. In 2026, international tax planning structures can determine whether income is reported directly, included under CFC rules, or disclosed on Form 8858 or Form 8865.
The following 4 structures show the usual US federal starting point and principal information return:
- Foreign branch. Income is generally reported by the US owner; Form 8858 can apply, and the income may fall in the foreign branch Foreign Tax Credit category.
- Foreign subsidiary or CFC. The corporation is separate, but U.S. shareholders can have Subpart F or section 951A NCTI inclusions before distributions, with Form 5471 reporting.
- Foreign disregarded entity. Its activity is generally treated as the US owner’s for federal income tax, while Form 8858 can still be required.
- Foreign partnership. A US partner generally reports a distributive share; Form 8865 can apply based on control, ownership, contributions, or transactions.
Entity structure is one of the most consequential international tax planning for business decisions because it affects income recognition, information returns, and later distributions.
A foreign LLC label under local law does not decide its US classification. TFX’s foreign disregarded entity and Form 8858 guide explains why disregarded treatment can simplify income taxation while leaving an information-return duty.
FBAR and FATCA compliance: the reporting backbone of international tax planning
FBAR and FATCA are 2 separate foreign-asset reporting systems. For calendar year 2025, FinCEN Form 114 applies when aggregate foreign financial accounts exceed $10,000 at any time, while Form 8938 uses higher thresholds that vary by filing status and whether the taxpayer lives in the United States or abroad.
TFX’s FBAR versus Form 8938 comparison explains the overlap. FBAR filing requirements govern foreign bank account reporting under the Bank Secrecy Act; FATCA compliance and Form 8938 reporting are part of the federal income tax return and can cover accounts plus other specified foreign financial assets.
The IRS FATCA overview describes Form 8938 as an individual reporting obligation that is separate from foreign financial institutions’ FATCA duties. Filing one form does not replace the other, and an asset can be relevant to both systems if each set of rules is met.
The old $10,000 and $100,000 FBAR penalty figures are no longer the current inflation-adjusted amounts. As of October 9, 2026, the 2025 adjusted ceilings remain in use: up to $16,536 for a non-willful violation and a $165,353 statutory dollar amount for willful violations, with willful penalties also tied to 50% of the account balance under the statute. OMB canceled a new 2026 inflation adjustment, so agencies continue using the 2025 figures.
Penalty assessments depend on the violation, reasonable-cause rules, willfulness, statutory limits, and case law. The Supreme Court’s Bittner decision treats non-willful FBAR penalties on a per-report, not per-account, basis, so the older shorthand of a separate non-willful maximum for every account should not be repeated as a blanket rule.
Form 8938 vs FBAR: thresholds, forms, and filing deadlines
FBAR and Form 8938 differ in 4 ways: threshold, asset scope, destination, and deadline. For a taxpayer abroad in 2025, FBAR starts above $10,000 of aggregate foreign accounts, while the IRS Form 8938 thresholds start at $200,000 year-end for a non-joint filer and $400,000 for joint filers.
For a taxpayer living abroad, the $10,000 FBAR threshold is far lower than the Form 8938 thresholds, but the forms report different asset sets and go to different destinations.
| Requirement | Form | Filing threshold abroad | Filing threshold US-based | Filing deadline | Filed with |
|---|---|---|---|---|---|
| FBAR | FinCEN Form 114 | > $10,000 aggregate at any time | Same > $10,000 aggregate | April 15; automatic extension to October 15 | FinCEN |
| FATCA | Form 8938 | Non-joint: > $200,000 year-end / > $300,000 anytime; joint: > $400,000 / > $600,000 | Non-joint: > $50,000 / > $75,000; joint: > $100,000 / > $150,000 | With income tax return, including extensions | IRS |
The TFX Form 8938 guide explains which specified foreign financial assets enter the FATCA calculation and how the residence-based thresholds apply. FBAR uses a different asset definition and a much lower aggregate-account threshold.
FBAR goes to FinCEN, while Form 8938 is attached to a federal income tax return filed with the IRS. TFX’s FBAR guide explains the separate account-reporting rules, including joint and signature-authority situations.
Tax treaty benefits: how to avoid double taxation legally
US income tax treaties can reduce double taxation, but the result depends on the treaty article, income type, residence facts, and saving clause. A treaty claim that overrides or modifies the Internal Revenue Code and reduces tax generally requires Form 8833 disclosure, although Treasury regulations provide exceptions.
Treaty provisions can change withholding rates on dividends, interest, or royalties and can assign residence under tie-breaker rules for eligible dual residents. TFX’s guide to double taxation for self-employed expats shows why a treaty’s income-tax rules and a Social Security totalization agreement must be analyzed separately.
Tax treaty benefits are not a single election that automatically applies to every item on Form 1040. Some provisions are claimed through withholding forms, some through the return itself, and certain treaty-based return positions need Form 8833; the saving clause can also preserve US taxation of citizens despite other treaty language.
A treaty-based return position that changes the Code and reduces US tax generally belongs on Form 8833 unless a regulatory exception applies. That is more precise than saying every treaty benefit must be disclosed on Form 8833.
International real estate tax planning for US expats
International real estate tax planning starts with 3 US questions: how rental income is reported, how a sale is taxed, and whether related accounts trigger FBAR or Form 8938. Foreign rental real estate is reported in US dollars on Schedule E, while direct ownership itself is not an FBAR account.
TFX’s foreign rental property tax guide explains Schedule E reporting, depreciation, and currency conversion. Eligible foreign income taxes imposed on the same foreign-source rental income may support a Form 1116 Foreign Tax Credit, subject to the credit limitation and the character of the tax.
On sale, IRC section 121 can apply to a main home outside the United States if the ownership, use, and other eligibility rules are met. The general maximum exclusion is $250,000 of gain, or up to $500,000 for qualifying joint filers, but depreciation and periods of nonqualified use can leave part of the gain taxable.
Direct foreign real estate is also not a specified foreign financial asset on Form 8938. If the property is held through a foreign corporation, partnership, trust, or estate, the ownership interest in that entity can be a Form 8938 asset, and a foreign bank account used to collect rent can be reportable under FBAR and FATCA rules.
International real estate tax planning must report foreign rental income in US dollars, while eligible foreign income tax on the same income may support a Foreign Tax Credit. The Form 1116 result depends on sourcing, category, and limitation rules.
Offshore tax planning: legal strategies vs. illegal tax evasion
Legal offshore tax planning uses disclosed structures, treaty provisions, credits, elections, and timing rules; tax evasion hides income, ownership, or accounts. In 2026, a US person with foreign accounts above the $10,000 FBAR aggregate threshold still has a reporting duty even when the account produces no taxable income.
TFX’s article on foreign account transparency under FATCA explains why offshore banking is not synonymous with secrecy. FATCA requires participating foreign financial institutions and certain other entities to identify and report information about US account holders, while the taxpayer can have separate FBAR and Form 8938 duties.
Deliberately filing a false return or intentionally failing to report a foreign account can move a case beyond civil compliance. An IRS Criminal Investigation case involving false returns and a foreign bank account illustrates the difference between a filing mistake and alleged conduct prosecutors treat as willful.
The legal line is disclosure and compliance: using a foreign account or entity is lawful, while intentionally concealing taxable income or a required foreign-account report can create civil or criminal exposure, including fines and imprisonment in prosecuted cases. The Streamlined Filing Compliance Procedures are a correction path for eligible non-willful taxpayers, not protection for willful evasion.
Streamlined filing procedures: catching up on missed international filings
The IRS streamlined filing procedures let eligible non-willful taxpayers correct past US filings with a limited lookback: 3 years of delinquent or amended income tax returns and 6 years of delinquent FBARs whose due dates have passed. The taxpayer must certify under penalties of perjury that the conduct was non-willful.
TFX’s guide to the streamlined filing procedures explains the return package and certification requirements.
Under the foreign track, eligible taxpayers can qualify for a 0% Title 26 miscellaneous offshore penalty. TFX’s Streamlined Foreign Offshore Procedures guide explains the nonresidency requirement and the records needed for the covered returns and FBARs.
The domestic track uses a 5% Title 26 miscellaneous offshore penalty on the specified penalty base, calculated under the program’s asset-value rules. Tax and statutory interest can still be due under either track, and the streamlined submission does not convert unpaid tax into penalty-free income.
Eligible Streamlined Foreign Offshore filers face a 0% Title 26 miscellaneous offshore penalty, while Streamlined Domestic Offshore filers generally face a 5% miscellaneous offshore penalty. Those percentages do not remove the requirement to file complete returns, pay tax and interest due, and provide an accurate non-willful certification.
International tax planning for high-net-worth individuals and wealth protection
International tax planning for high-net-worth individuals should test at least 5 areas before a major move or transfer: foreign trusts, estate and gift tax, pre-immigration timing, expatriation, and PFIC exposure. For calendar year 2026, one covered-expatriate tax-liability threshold is $211,000, while the separate net-worth test remains $2 million.
The following 5 areas deserve separate modeling because each has its own forms, timing rules, and definitions:
- Foreign trusts. Contributions, ownership, and distributions can trigger Form 3520 and sometimes Form 3520-A. TFX’s guide to relief for certain tax-favored foreign trusts explains a narrow reporting exception, not a blanket exemption for every foreign pension or trust.
- Estate and gift planning. Cross-border transfers require both US and local-law analysis. For 2026, the federal basic exclusion amount is $15 million for US citizens and domiciliaries, while noncitizens and nondomiciliaries can face different situs and treaty rules.
- Pre-immigration planning. A future US resident can sometimes time realizations, entity restructuring, or ownership changes before becoming subject to US worldwide income taxation, but anti-abuse, basis, and immigration-tax residency rules must be checked before any transaction.
- Expatriation under IRC section 877A. TFX’s expatriation and estate tax guide covers the covered-expatriate tests. For 2026, the average annual net income tax liability threshold is more than $211,000, the net-worth test is $2 million, and the mark-to-market gain exclusion is $910,000.
- Offshore investments and PFICs. Foreign mutual funds, ETFs, or insurance wrappers can be PFICs and trigger Form 8621, current inclusions, excess-distribution rules, and interest charges depending on elections and history.
A person who expatriates in 2026 can be a covered expatriate by meeting the $211,000 average tax-liability test, the $2 million net-worth test, or failing the 5-year tax-compliance certification, subject to statutory exceptions for certain dual citizens and minors. Form 8854 is central to that determination.
PFIC rules: the hidden tax trap in foreign investment portfolios
A foreign corporation is generally a PFIC if at least 75% of gross income is passive or at least 50% of average assets produce, or are held to produce, passive income. A US person can face Form 8621 reporting and tax calculations for a familiar foreign mutual fund or ETF.
TFX’s foreign investment guide for expats explains why local investment products can create US reporting that does not exist in the country where the fund is sold. Under the default excess-distribution regime, certain distributions and gains are allocated over the holding period and can carry an interest charge.
A QEF election can replace the default regime with current inclusion of the shareholder’s share of PFIC ordinary earnings and net capital gain when the fund supplies the required information. The cleanest result is generally a timely election from the first PFIC year; later elections can require deemed-sale, deemed-dividend, or qualified retroactive-election rules.
Foreign mutual funds, ETFs, and insurance-based investments can create PFIC treatment, and the tax cost of selling an unplanned PFIC can exceed the current-year gain calculation because prior-year allocations and interest charges can apply. Form 8621 needs to be reviewed before disposition, not after the cash is spent.
Transfer pricing and GILTI: international tax planning for US-owned foreign businesses
Two 2026 rules matter for a US owner transacting with a foreign business: IRC section 482 still requires arm’s-length pricing, while revised section 951A calculates net CFC tested income, or NCTI, for tax years beginning after December 31, 2025. GILTI remains the pre-2026 term.
TFX’s specified foreign corporation overview provides related CFC context. For 2026, current IRS guidance says the statutory NCTI computation removes the former QBAI routine return and tested-interest components.
International corporate tax planning must also account for revised foreign tax credit mechanics. International tax planning for corporations using an eligible domestic corporation can include a 40% section 250 deduction for NCTI and the related section 78 amount, subject to the taxable-income limitation, while section 960(d) now uses a 90% deemed-paid foreign tax percentage.
The pre-2026 statement that GILTI applies only after a routine return on tangible assets is outdated for 2026. Revised section 951A uses NCTI and removes QBAI from the statutory computation, so 2026 modeling should not reuse the old 10% QBAI formula. The same update can change projected cash-tax costs and credit utilization.
Tax residency planning: how where you live affects your US tax obligations
Tax residency planning changes foreign, treaty, and state tax outcomes, but it does not switch off US citizenship-based taxation. In 2026, foreign residence can support the Form 2555 bona fide residence test, while treaty residence can affect eligible dual residents and state exposure follows each state’s own rules.
US citizen abroad taxes still start with worldwide income on the federal return. A treaty tie-breaker can resolve residence for certain treaty purposes, but the saving clause in many treaties preserves US taxation of citizens, so the exact article and any Form 8833 requirement must be checked rather than treating treaty residence as a universal federal exit.
State tax is a separate layer. TFX’s discussion of foreign entities and offshore corporation considerations is useful when residence changes coincide with business ownership, but California, New York, Virginia, and other states each apply their own residence and domicile tests; a foreign address alone does not settle those rules.
Foreign tax residence can support FEIE, treaty, and host-country positions, while US federal citizenship-based filing and state residency rules remain separate tests. A defensible move file should document dates, housing, family ties, business activity, registrations, and the state facts that support a claimed change of domicile.
International tax planning examples: real-world scenarios
These 3 international tax planning examples show why the same income amount can produce different US results based on country, income type, and entity structure. Each scenario names the strategy, form, and likely outcome, but uses simplified figures that do not replace the taxpayer’s actual sourcing and foreign-tax data.
Based on our client scenario at TFX: A software engineer resident in Germany earns €120,000 of German salary and pays German income tax on it. Strategy: test Form 1116 before Form 2555. Form: Form 1116 with the US return. Outcome: if eligible German income taxes exceed the US tax attributable to that foreign-source general-category income within the FTC limitation, the residual US income tax on the salary can be $0. TFX’s FEIE denial case study shows why qualification and documentation still matter.
Also, A freelancer living in Thailand has $115,000 of qualifying 2025 foreign earned income and meets the physical presence test for a 12-month period. Strategy: claim FEIE. Form: Form 2555. Outcome: The income is below the $130,000 2025 FEIE ceiling, so qualifying earned income may be excluded from US income tax, but US self-employment tax can remain. The FEIE should also be considered alongside financial-aid effects discussed in TFX’s FEIE and FAFSA guide.
We also had a US citizen in Canada who owns 100% of a Canadian corporation that is a CFC. Strategy: model Subpart F income, 2026 NCTI, foreign taxes, and a section 962 election. Forms: Form 5471, Form 8992 as applicable, and the section 962 election statement. Outcome: the election can change current US tax and deemed-paid foreign tax credits, but later distributions must be modeled before choosing it.
The right strategy depends on country of residence, income type, foreign tax rate, and business structure. That is why an international tax plan should compare the actual Form 2555, Form 1116, CFC, and treaty results rather than copy an outcome from another expat with different facts.
The principles of international tax planning: a framework for compliance and optimization
The principles of international tax planning can be reduced to 6 operating rules: map reporting, put compliance first, use the right form, model multiple years, coordinate both countries, and review annually. For 2026, that review matters because section 951A changed from the former GILTI formula to NCTI.
The following 6 principles keep a cross-border tax plan tied to filing reality:
- Map worldwide reporting first. Identify income, accounts, entities, trusts, and investments before choosing exclusions or credits.
- Put compliance before tax reduction. Do not create a tax saving that leaves an information return or treaty disclosure unsupported.
- Use the correct form. FBAR goes to FinCEN; Form 8938 and most income-tax forms go with the federal return.
- Model more than 1 year. FEIE elections, credit carryovers, PFIC elections, section 962, and restructuring can affect later years.
- Coordinate US and foreign positions. Compare host-country tax, withholding, social insurance, treaty rules, and the US result.
- Review annually. Income mix, residence, ownership, thresholds, and international tax laws can change the answer.
Sound international tax plans start with full compliance – a tax-saving strategy that triggers penalties and interest is not sound planning. TFX’s delinquent international information return procedures guide explains why late information returns require separate correction analysis.
International tax consulting and international tax accounting are most useful when they connect these rules to a filed return. So, what is international tax planning and wealth protection in practice? It applies the same reporting-first discipline to ownership, succession, entity, and investment decisions before a taxable event fixes the result.
Frequently asked questions
International tax planning coordinates US and foreign tax rules before income, asset, or business decisions are finalized. US expats may need it because Form 1040 can cover worldwide income while Form 2555, Form 1116, FBAR, and Form 8938 apply separate tests. The aim is lawful global income tax minimization with complete reporting, not concealment.
Form 2555 excludes qualifying foreign earned income up to $130,000 for tax year 2025 and $132,900 for 2026, while Form 1116 credits eligible foreign income tax against US tax within a limitation. The 2 tools can coexist on a return, but foreign taxes tied to excluded income cannot also generate a credit. The IRS physical presence test uses 330 full days in a 12-month period.
Living abroad does not exempt a US person from FBAR. FinCEN Form 114 is required when the aggregate value of reportable foreign financial accounts exceeds $10,000 at any time during the calendar year, and the person has a financial interest in, or reportable authority over, the accounts. TFX’s FATCA exemptions guide covers the separate Form 8938 rules.
An eligible non-willful taxpayer may be able to use streamlined filing procedures, usually covering 3 income-tax returns and 6 FBARs whose due dates have passed. The foreign track can carry a 0% Title 26 miscellaneous offshore penalty, but tax and interest can still be due. Eligibility and the non-willful certification should be reviewed before filing.
For tax years beginning before 2026, GILTI was the section 951A inclusion regime for U.S. shareholders of CFCs. For tax years beginning after December 31, 2025, revised section 951A uses NCTI instead. A small business owner can still be affected if the ownership rules make the foreign company a CFC and Form 5471 or Form 8992 applies.
A foreign corporation can change timing, rates, foreign tax credits, and reinvestment options, but it does not automatically reduce US tax. A 10% U.S. shareholder can face Form 5471 reporting, and a CFC can create Subpart F or NCTI inclusions before cash is distributed. International tax planning for business should model entity and distribution results together.
A PFIC is generally a foreign corporation that meets the 75% passive-income test or 50% passive-asset test. Foreign mutual funds and ETFs can qualify. Form 8621, excess-distribution taxation, interest charges, QEF elections, or mark-to-market rules can follow, so a fund that looks ordinary locally can create a very different US tax result.
Tax treaties can lower withholding, assign taxing rights, define residence, or provide other double taxation relief, depending on the country and income article. The savings clause can preserve US taxation of citizens, and some treaty-based return positions require Form 8833. Treaty language should be read alongside Form 1116 and any applicable totalization agreement.
TFX’s Form 2555 and foreign earned income guide adds filing detail. International tax laws change by tax year and treaty, so confirm current form instructions and the applicable treaty article before relying on a prior-year position.
