1. International Tax Services Begin with Income and Ownership
Foreign statements, share transfers, and late tax certificates raise different filing questions. A review identifies the taxpayer, relevant transactions, and tax years before selecting a legal response.
Foreign Income Depends on Federal Tax Status
U.S. citizens and federal tax residents generally report worldwide income. Nonresident aliens follow separate rules for U.S.-source income and income effectively connected with a U.S. business. A green card, the substantial-presence test, or a treaty may change federal classification; an overseas employer's payroll label does not establish residency.
Compare foreign payroll records, rental ledgers, dividend statements, and returns with U.S. filings. Check when income arose and whether foreign tax was paid, accrued, or refunded. Different reporting periods may explain discrepancies. An attorney can evaluate the legal characterization while coordinating tax calculations.
Foreign Accounts and Company Interests Create Separate Duties
A U.S. person generally must file an FBAR (FinCEN Form 114) when the aggregate value of reportable foreign financial accounts exceeds $10,000 at any point during the calendar year. Financial interest or signature authority matters even without income. Form 8938 covers specified foreign financial assets under different filer and value thresholds; filing either form does not replace the other.
Form 5471 can apply to U.S. officers, directors, or shareholders of certain foreign corporations. Ownership and acquisition dates matter even without dividends. Revised rules for foreign corporation tax years beginning after 2025 can also affect shareholder income inclusions. Related international tax compliance requirements cover those corporate rules in greater detail.
2. Federal and California Tax Rules Can Produce Different Results
Federal relief does not settle California tax liability. Residency, income sourcing, and available credits require separate analysis after a move or foreign tax adjustment.
Foreign Tax Credits and Treaties Have Defined Limits
Internal Revenue Code § 901 may allow a credit for qualifying foreign income taxes, subject to limitations. Treaty relief, refunds, or later assessments may change the tax eligible for credit. Compare foreign assessments and payments against the U.S. return.
The § 911 foreign earned income exclusion generally requires a foreign tax home and qualifying residence or physical presence abroad. Taxes on excluded earnings cannot also generate a foreign tax credit. Treaty benefits depend on the particular agreement and taxpayer's status. If the IRS disputes a federal position, federal tax lawyer representation addresses the resulting administrative or court process.
California Residency Calls for an Independent Review
The Franchise Tax Board considers presence in California for other than a temporary or transitory purpose, or California domicile during a temporary absence. Residents generally report worldwide income. Part-year residents report worldwide income during residency and California-source income during nonresident periods. Nonresidents generally owe tax on California-source income.
California does not allow a foreign earned income exclusion or a foreign tax credit for foreign-country taxes. Federal income tax treaties generally do not govern state liability. Travel, housing, work locations, and deferred compensation may change the state result. Businesses operating within Los Angeles city limits can face separate business-tax registration rules, unrelated to federal account reporting.
3. Missing International Filings Require the Right Correction Route
Late FBARs, omitted corporate returns, and unreported income require different responses. The route depends on the affected years, reasons for omission, and agency contact.
Distinguish Tax Underpayments from Information-Return Gaps
Compare federal returns with overseas income, account, and ownership records. File FBARs through FinCEN's BSA E-Filing System, not with Form 1040. The annual FBAR deadline is generally April 15, with an automatic extension to October 15. Forms 8938 and 5471 generally accompany the applicable income tax return.
An omitted information return can trigger penalties without additional tax due. Delinquent returns may require amended filings and a reasonable-cause explanation, but relief is not automatic. Check agency letters before submitting statements that conflict with earlier records.
Non-Willful Corrections Differ from Voluntary Disclosure
IRS Streamlined Filing Compliance Procedures require eligible taxpayers to certify non-willful conduct, such as negligence, mistake, or a good-faith misunderstanding. If the IRS has initiated a civil examination of the taxpayer's returns or an IRS criminal investigation, the streamlined route is unavailable. Domestic and foreign streamlined procedures also have different residency and penalty rules.
Potentially willful violations require separate review. The IRS Criminal Investigation Voluntary Disclosure Practice involves preclearance and timely, truthful, complete disclosure. It does not guarantee immunity from prosecution. Prior advice, bank letters, and agency contact may affect eligibility. The IRS voluntary disclosure process explains that distinct route rather than treating every late return as a voluntary disclosure.
4. Document Review Connects Foreign Records with Agency Deadlines
A case review maps reporting errors to agency procedures and deadlines. Attorneys assess disputed residency, ownership, and legal obligations while accountants handle necessary computations.
Reconcile Foreign Records by Country and Tax Year
Build a timeline of relocation, employment, accounts, and acquisitions. Bank statements show balances; contracts identify work locations; corporate registers establish direct and indirect interests. Match foreign tax assessments, payment receipts, and refunds against credits claimed in the United States.
Preserve original documents, correspondence, and exchange-rate records. Missing statements or unexplained deposits can affect income and account disclosures. An attorney can assess evidence gaps and conflicts before responding to an agency.
Identify the IRS, Fincen, and FTB Response Paths
The IRS administers federal tax and related international information returns. FinCEN receives FBARs, which the IRS can also enforce under delegated authority. The FTB handles California income tax disputes. An FTB Notice of Proposed Assessment generally allows 60 days for a protest; a subsequent Notice of Action generally allows 30 days to appeal to the Office of Tax Appeals. Check the deadline on the notice itself.
A federal Notice of Deficiency generally allows 90 days after mailing to petition the U.S. Tax Court, or 150 days in qualifying overseas circumstances. Collection notices follow separate rules. Our IRS tax attorney guide on bank levy notices addresses those federal collection rights, not rules specific to New York.
