IRS audit defense is a record-first process. It does not mean arguing with every request. It means understanding what return item is being examined, supplying reliable and organized support, avoiding unrelated disclosure, and documenting disagreements and procedural rights.
“Defense” on this independent educational site means preparing an accurate record, understanding public rights and procedures, and choosing an official response channel. The site does not defend or represent taxpayers and does not review private files.
Start with four facts
Exact notice, letter, form, report, lien, levy, or court document.
Taxpayer, entity, form, tax period, amount, and requested action.
Notice date, response date, filing date, and objective delivery proof.
Return, transcript, payment, financial, or issue-specific evidence.
Important distinctions
Correspondence audit
Written requests usually focus on selected items. A numbered exhibit index and delivery proof are central.
Office audit
The taxpayer or representative generally meets at an IRS office. Prepare the requested file and the interview scope.
Field audit
A field examination can involve a home, business, or representative's office and broader books and records.
Reconsideration or appeal
Audit reconsideration, manager review, administrative Appeals, and Tax Court are different stages with different triggers and deadlines.
Build the working file
Use copies for the working file and keep original records secure. Create an issue index before drafting a long explanation.
- Audit opening letter and document request
- Return and schedules for each year
- Issue-to-evidence index
- Receipts, statements, logs, contracts, and third-party forms
- Examiner submissions and contact log
- Examination report, protest, and delivery proof
A practical response path
- List each tax year, form, income item, deduction, credit, or business issue the examiner identified.
- Create an exhibit index that maps every requested item to a return line and supporting record.
- Separate complete, partial, missing, and potentially substitutable records before drafting explanations.
- Review interview, representation, extension, manager, and Appeals questions before the next contact.
- Log every submission, conversation, proposed adjustment, agreement, and unresolved issue.

Do not rely on a general guide alone
Seek prompt qualified help when a court or appeal deadline, active levy, payroll tax, responsible-person interview, possible fraud issue, large business adjustment, bankruptcy interaction, sensitive spouse facts, or threat to essential living expenses is present.
Questions readers often ask
Can an IRS audit be fought?
A taxpayer can challenge proposed findings and provide records, explanations, and appeals where the rules permit. The practical first task is to identify each adjustment and the evidence or issue supporting disagreement.
Should I send every tax record I have?
Usually no. Answer the actual request with an indexed file. Broad, unrelated submissions can create confusion and expose unnecessary private information.
When may representation matter?
Consider qualified help for interviews, broad field examinations, missing records, large adjustments, business or payroll issues, foreign reporting, potential fraud concerns, or appeal and court deadlines.
