1. What International Tax Matters Can a Lawyer Handle?
International tax disputes may begin with an IRS notice, an unreported foreign account, or discrepancies between financial records and tax returns. An attorney identifies the applicable obligations and evaluates the taxpayer's legal position.
Foreign Income and Overseas Accounts
U.S. citizens and resident aliens generally must report worldwide income on federal returns. Separate disclosure rules may apply to foreign accounts, investments, and business interests.
An attorney compares foreign financial statements with prior returns to identify unreported income, missing disclosures, and potential penalties. A reporting violation can exist even without additional taxable income.
Cross-Border Business Transactions
Foreign corporations, partnerships, and related-party transactions may trigger federal reporting requirements.
Forms 5471, 8865, and 8858 apply to certain foreign business interests. IRC §482 also allows the IRS to allocate income and deductions among controlled taxpayers to prevent tax evasion or clearly reflect income.
For businesses operating internationally, international tax compliance may require reviewing ownership structures, intercompany agreements, and transfer pricing records.
Controlled Foreign Corporation Taxation
Certain U.S. shareholders of controlled foreign corporations may owe federal tax on foreign earnings without receiving distributions.
Subpart F addresses specified foreign corporation income. For tax years beginning after December 31, 2025, IRC §951A generally applies the net CFC tested income framework instead of the former GILTI calculation.
Ownership percentages, income classification, and applicable deductions affect the resulting tax obligations.
2. Which Foreign Assets Require Federal Reporting?
Foreign asset reporting depends on the taxpayer's status, ownership rights, asset type, and applicable thresholds. Different filing requirements may apply to the same financial interest.
FBAR, FATCA, and Foreign Entity Filings
| Filing | General Reporting Requirement |
|---|---|
| FBAR, FinCEN Form 114 | Aggregate foreign financial accounts exceed $10,000 at any time during the calendar year |
| FATCA, Form 8938 | Specified foreign financial assets exceed applicable reporting thresholds |
| Form 5471 | Certain reportable relationships involving foreign corporations |
| Form 3520 | Certain foreign trust transactions and qualifying foreign gifts or bequests |
FBAR, FinCEN Form 114
- General Reporting RequirementAggregate foreign financial accounts exceed $10,000 at any time during the calendar year
FATCA, Form 8938
- General Reporting RequirementSpecified foreign financial assets exceed applicable reporting thresholds
Form 5471
- General Reporting RequirementCertain reportable relationships involving foreign corporations
Form 3520
- General Reporting RequirementCertain foreign trust transactions and qualifying foreign gifts or bequests
FBAR may apply to foreign accounts held through a financial interest or signature authority. Form 8938 covers specified foreign financial assets and uses different thresholds. Filing one does not replace the other.
Direct foreign real estate ownership generally does not trigger either filing solely because of the property's location. Holding property through a foreign entity may create additional obligations.
Records Needed for a Tax Case Review
An attorney may request:
- Federal and California income tax returns.
- Foreign account statements showing maximum annual values.
- Business ownership and transaction records.
- Previously filed international information returns.
- Foreign tax payment records and IRS correspondence.
These documents establish ownership, reporting history, and potential discrepancies. Account values help assess FBAR requirements, while corporate records may reveal foreign entity disclosure obligations.
3. How Can a Lawyer Respond to IRS International Tax Investigations?
The appropriate response depends on whether the IRS has requested information, proposed a penalty, or opened an examination. Taxpayers who discover earlier filing failures must also determine whether voluntary correction procedures remain available.
IRS Examination and Penalty Defense
An IRS notice may question foreign income, request account records, or propose penalties for incomplete disclosures.
During an IRS audit, an attorney can respond to document requests, examine disputed findings, and challenge applicable penalties.
Defenses may involve reasonable cause, factual errors, or the absence of willfulness when relevant to the governing penalty provision. A reporting failure alone does not establish criminal tax fraud.
Streamlined Filing Compliance Procedures
The IRS Streamlined Filing Compliance Procedures permit qualifying individual taxpayers to correct certain non-willful failures involving foreign income and information returns.
Applicants must satisfy eligibility requirements and certify that their conduct was non-willful.
These procedures generally become unavailable after the IRS initiates a civil examination of the taxpayer's returns for any tax year or an IRS Criminal Investigation investigation.
Voluntary Disclosure and Tax Disputes
Potentially willful violations require separate consideration, including possible eligibility for the IRS Criminal Investigation Voluntary Disclosure Practice.
Participation does not guarantee protection from prosecution or eliminate civil penalties.
When an examination produces disputed findings, tax controversy representation may involve administrative appeals, penalty challenges, or judicial remedies. Available procedures depend on the notice, examination stage, and statutory deadlines.
4. How Do Federal and California International Tax Rules Differ?
Federal international reporting compliance does not resolve every California income tax issue. State residency, income sourcing, and tax treatment must be evaluated separately.
California Residency and Foreign Income
California generally taxes residents on worldwide income. Nonresidents are generally taxed on California-source income, while part-year residents follow rules based on their residency periods.
Unlike federal law, California does not allow the federal foreign earned income exclusion or a comparable foreign tax credit.
Federal income tax treaty benefits also do not necessarily apply to California taxation.
Federal Adjustments and State Proceedings
The IRS administers federal tax examinations, while the California Franchise Tax Board handles state income tax matters.
Federal adjustments may affect California returns, and qualifying changes generally must be reported to the FTB within applicable deadlines.
State disputes follow separate administrative procedures. In federal proceedings, tax representation may include IRS appeals or litigation before an appropriate federal forum.
5. Frequently Asked Questions
A foreign inheritance generally does not constitute taxable federal income merely because it is received. However, a U.S. person who receives more than $100,000 in aggregate gifts or bequests from nonresident alien individuals or foreign estates, including certain related persons, generally must report the receipt on Form 3520.
An inherited foreign account may also trigger FBAR or Form 8938 reporting when the recipient holds a qualifying interest and meets applicable thresholds.
