Tax Controversy and Litigation: Strategy for Every Stage of a Dispute

An IRS audit examination begins with a written notice specifying the tax years and issues under review. The IRS has broad summons authority, but attorney-client privilege and work product protection remain fully applicable during audits. Procedural missteps by the IRS, including unauthorized expansion of examination issues, can void any resulting tax assessment. Tax controversy and litigation counsel who participates from the audit stage often resolves disputes without ever reaching Tax Court.

When an IRS examination produces a proposed adjustment, taxpayers may contest the finding through the IRS Independent Office of Appeals. Administrative tax appeals offer a less expensive and faster alternative to tax court litigation for many disputes. Most IRS disputes that reach the Appeals level are resolved without litigation, making this stage critical to any defense strategy. Counsel can build a factual and legal record at Appeals that supports tax court litigation if negotiation fails.

The IRS applies the substance over form doctrine when a transaction's form appears to conflict with its economic substance. Courts have consistently held that legitimate tax planning is lawful, but transactions lacking independent economic substance can be recharacterized. Defending against this doctrine requires demonstrating a genuine non-tax business purpose present when the transaction was structured. Documentation of business rationale, market conditions, and third-party participation strengthens the taxpayer's position before the IRS and in court. Tax controversy and litigation counsel can challenge IRS recharacterization under the economic substance rules codified in IRC Section 7701(o).

Transfer pricing disputes arise when the IRS challenges related-party transaction prices as inconsistent with the arm's length standard. The IRS may impose significant adjustments under IRC Section 482, requiring the taxpayer to document contemporaneous economic justification. Taxpayers may seek competent authority relief under international tax compliance frameworks and applicable U.S. tax treaties to eliminate double taxation from a transfer pricing adjustment. FBAR and FATCA compliance failures accompanying international tax disputes significantly increase civil penalty exposure and the risk of criminal referral.

A notice of deficiency, also called a ninety-day letter, gives the taxpayer ninety days to petition the U.S. Tax Court. Filing a Tax Court petition suspends the IRS's ability to collect the contested deficiency while the case is pending. Tax court litigation proceeds through discovery, pre-trial stipulations, and a trial before a Tax Court judge without a jury. Small Tax Court cases under fifty thousand dollars follow a simplified procedure, but their decisions are not precedential. Experienced tax controversy and litigation counsel can often negotiate a settlement with IRS counsel before the case reaches trial.

A taxpayer who overpaid federal income tax may file a refund claim with the IRS, subject to strict statutes of limitations. Refund claims are generally limited to three years from the filing date or two years from the payment date. If the IRS denies a refund claim, the taxpayer may sue for corporate tax refund and recovery through federal district court. Tax controversy and litigation counsel must evaluate the statutes of limitations at the outset, as a missed deadline bars any recovery.

Civil tax fraud under IRC Section 6663 requires proof by clear and convincing evidence of intentional tax evasion. Criminal tax evasion under IRC Section 7201 requires the government to prove willfulness beyond a reasonable doubt, the highest legal standard. Common defense strategies in tax fraud and evasion cases challenge the evidence of willfulness by demonstrating reliance on professional advice. The IRS uses badge of fraud factors, including unreported income and false deductions, to establish evidence of fraudulent intent. Establishing that discrepancies resulted from negligence or reliance on advisors negates the willfulness required for criminal tax prosecution.

The IRS Voluntary Disclosure Practice allows taxpayers with unreported income or offshore accounts to come forward and limit criminal exposure. Voluntary disclosure is not an amnesty program, but it typically results in civil rather than criminal resolution. Abatement of tax delinquency and penalties based on reasonable cause is available when noncompliance results from circumstances beyond the taxpayer's control. First-time penalty abatement is available administratively without requiring a showing of reasonable cause, covering one tax year per taxpayer. Tax controversy and litigation counsel advising on disclosure must balance the benefits of cooperation against the risk of an expanded examination.
