Audit Defense Done Right: Control the Scope, Control the Outcome

Every audit has a scope: specific years, specific issues, listed in the opening letter. The single most important principle of audit defense is keeping the examination inside that scope - because audits do not go badly over the issues on the list nearly as often as they go badly over the things taxpayers volunteer.

The Discipline

Represented audits run on paper. The examiner sends an information document request; counsel responds with exactly what was asked, organized, indexed, complete. No banker's box of everything. No chatty cover letters. No meetings where nervous answers wander into new territory. In most of my audits, the client never speaks to the examiner at all - that is not evasion, it is the procedure working as designed, and examiners are accustomed to it.

Organization itself is advocacy. An examiner who receives clean schedules tied to documents closes issues and moves on. An examiner wading through chaos starts estimating, and estimates never favor you.

The Substantiation Fight

Most audit dollars are won or lost on substantiation - proving the deductions. Missing records are not fatal: the law permits reasonable reconstruction, and bank records, vendor statements, calendars supporting mileage logs, and industry data can rebuild what shoeboxes lost. Courts have long accepted that imperfect records can still substantiate real expenses. The difference between a conceded deduction and a defended one is usually effort, not evidence.

On business audits, expect the bank deposit analysis: every deposit presumed income until proven otherwise. The loan from family, the transfer between your own accounts, the insurance reimbursement - each needs a document. Preparing that proof before the examiner asks is the difference between a routine audit and an expanded one.

The Audit Is Round One

When the examination report arrives, you are not required to agree with it. Disagreement, filed on time, moves the case to Appeals, where settlement based on litigation hazards is the official mission - and where audit results change regularly. The examiner's report is a proposal. Treat it like one.

If an audit letter just landed, the response strategy starts before the first reply. Send me the letter before you answer anything.
