IRS Audit Defense for Complex Taxpayers and High-Stakes Issues

IRS audit defense should be organized around the examiner's issue, the taxpayer's evidence, the procedural timeline, and the representation boundary. MMVFO helps build the issue file, coordinate advisors, and escalate to counsel where privilege, legal strategy, or litigation risk is present.

Tax Controversy

Audit defense timeline

An IRS exam moves through IDRs, fieldwork, and a 30-day letter before appeals – each stage calls for a different posture.

Exam scope and issue map

Identify the tax years, issues, IDRs, deadlines, examiner requests, return positions, adjustments proposed, and records already provided.

Evidence reconstruction

Organize source documents, workpapers, contracts, accounting records, calculations, emails, third-party records, and advisor notes into a usable response file.

Position and response support

Coordinate factual analysis, schedules, narratives, exhibits, and return integration so responses match the taxpayer's actual support.

Representative and counsel lanes

CPAs, enrolled agents, and attorneys may represent taxpayers before the IRS in appropriate matters; privilege and legal strategy require counsel.

Resolution and cleanup

Track findings, appeals options, amended return needs, penalty exposure, state effects, and future compliance controls.

Scope and professional boundaries
