Multinational Offshore Tax Evasion Claims Require IRS Audit Defense

FATCA creates reporting and withholding duties for specified taxpayers, financial institutions, and withholding agents. Section 951A separately governs controlled-foreign-corporation tested-income inclusions. For taxable years beginning after 2025, the revised framework is generally described as net CFC tested income rather than GILTI. Forms 5471, 5472, 8858, 8865, 8938, and FBAR filings may apply based on ownership, accounts, and transactions. A focused international tax compliance review maps each obligation to the correct entity and year.

No single fact proves wrongdoing. Examiners may ask more questions when foreign entities report little operating substance or payments lack commercial support. A service fee in the ledger may appear as a royalty in the agreement. Unexplained transfers, missing information returns, and conflicting ownership records may also widen the examination.

Emails, board materials, tax memoranda, return workpapers, and advice received at the time may help explain why a position was taken. Later-created explanations carry less weight when they conflict with original records. Companies should preserve documents and avoid editing, backdating, or informally reconstructing evidence after an audit begins.

An accounting error is not fraud merely because it produces additional tax. Criminal tax evasion under IRC § 7201 requires a willful attempt to evade or defeat tax, while civil fraud under IRC § 6663 is a separate determination. Attorneys can distinguish issues requiring correction, defense, or escalation.

The company should assign responsibility for collecting, reviewing, and approving every response. A rushed email can create a new inconsistency, while an undocumented extension can cause a deadline dispute. Attorneys should prepare employees for interviews without scripting testimony or interfering with truthful answers.

In a transfer pricing examination, the IRS may request documentation early and compare contracts with functions, assets, risks, and actual decisions. A transfer pricing compliance review should test the selected method, comparable data, intercompany charges, and financial segmentation. Economic-substance or substance-over-form questions may also arise when transactions lack a credible business purpose or differ from their written terms.

Attorneys can direct the legal investigation and coordinate technical work. Accountants may reconstruct returns and quantify adjustments, while economists address pricing or valuation. Communications with an accountant do not become privileged merely because an attorney participates.

• Issue a targeted preservation notice for relevant records and communication systems.
• Map foreign entities, accounts, owners, signatories, and reporting obligations by year.
• Centralize IRS communications and maintain a complete response log.
• Reconcile tax returns with ledgers, contracts, bank data, and operational records.
• Escalate suspected intentional conduct before submitting further statements.

Before a response leaves the company, the team should be able to trace each factual statement to a document or witness. A submission can correct an inaccurate assumption, explain missing context, or suggest a practical production method. Negotiation should rest on verifiable facts and law, not predictions about the outcome.

IRC § 6662 generally authorizes a 20% accuracy-related penalty for specified underpayments. IRC § 6663 imposes a 75% civil fraud penalty on the portion attributable to fraud. The penalties cannot apply to the same portion of an underpayment. Tax due alone does not establish fraud because the IRS must show affirmative acts. A civil examination may involve fraud specialists and a referral to IRS Criminal Investigation. Criminal Investigation may later recommend prosecution to the Department of Justice, but neither step is automatic.

The IRS Voluntary Disclosure Practice addresses potential criminal exposure arising from willful violations. It requires timely, truthful, and complete cooperation and does not erase tax, interest, or civil consequences. Preclearance generally is unavailable after the IRS knows of the noncompliance or begins an examination or investigation. The IRS proposed revisions in 2026, so a company should confirm the current Form 14457 and procedures before pursuing voluntary disclosure.

Form 2848 identifies the representative and covered tax matters. Eligible attorneys, certified public accountants, and enrolled agents may represent taxpayers before the IRS. An authorized corporate officer must execute the form for a corporation. Attorneys may manage legal strategy, privilege, summons questions, and civil or criminal overlap, while tax professionals support calculations and return analysis.

An IRS resolution does not automatically settle state liability. Under New York Tax Law § 211(3), an Article 9-A taxpayer generally must report a final federal change within 90 days, or 120 days for a combined report. The same periods generally apply after the taxpayer files an amended federal return. State penalties and voluntary disclosure require separate analysis.

If an examination produces proposed adjustments, the taxpayer may have an opportunity to protest before the IRS Independent Office of Appeals. Appeals considers litigation risk but does not guarantee settlement. Depending on the notice and procedural posture, later options may include Tax Court proceedings, refund litigation, or other tax controversy and litigation procedures.
