IRS Audit Response Letter Checklist
Understanding Your Audit Response Letter
When the IRS sends you an examination letter, your written response becomes one of the most important steps in the audit process. Unlike general tax notices, audit letters require specific documentation and explanations for items the IRS has selected for review. Your response deadline is firm, and missing it allows the IRS to proceed with proposed adjustments based solely on their findings. This checklist guides you through responding effectively to protect your tax position and appeal rights.
Who Should Use This Checklist
This checklist applies to taxpayers who received an IRS examination letter requesting documentation or explanation for specific items on their tax return. It covers correspondence audits conducted by mail and initial responses to field or office examination notices. This guide does not apply to CP2000 underreporter notices, which are proposals based on income matching rather than formal audits. It also does not cover cases already in IRS Appeals or Tax
Court proceedings.
Step-by-Step Checklist
Step 1: Read the Entire Letter Carefully
Locate the response deadline, tax year under examination, and specific items the IRS is questioning on your return. Write down each item by line number or category so you address everything the IRS requested in your response.
Step 2: Calculate Your Response Deadline
Count the exact number of calendar days from the letter date to the stated deadline, which is typically 30 days from the date of the notice. Mark your calendar and plan to submit your response at least three business days early to avoid mail delays or processing issues.
Step 3: Identify What the IRS Needs
Determine whether the letter requests documents, explanations, or both by reading the specific language in each section. Call the IRS examiner at the provided phone number if the request is unclear, and document their response for your records.
Step 4: Gather Supporting Documents
Collect every document the IRS specifically listed in the letter before searching for additional materials that might help your case. Create a separate folder for each item being examined to keep your submission organized and easy for the examiner to review.
Step 5: Verify Document Accuracy
Compare each document against the amounts claimed on your tax return to ensure the numbers match or identify discrepancies you need to explain. Note any differences now so you can address them proactively in your response rather than waiting for IRS questions.
Step 6: Prepare Your Written Response
Write a brief explanation for each item if the IRS requested justification beyond documentation, keeping statements factual and directly answering what was asked. Use 2 to 3 sentences per issue and label each explanation with the corresponding tax form line or category from the audit letter.
Step 7: Organize Your Submission Package
Create a cover letter stating your name, taxpayer identification number, tax year, and examination period at the top of the page. List each item being examined and note what you are submitting for each one so the examiner can easily match documents to issues.
Step 8: Make Complete Copies
Photocopy everything you plan to submit, including the cover letter, document list, and all supporting materials, before mailing or uploading. Keep one full set with submission confirmation for your records in case the IRS claims they never received specific items.
Step 9: Submit Using the Correct Method
Follow the submission instructions in the audit letter, which may include secure upload portals, fax numbers, or mailing addresses specific to your case. Use certified mail with a return receipt if mailing documents to obtain proof of delivery and protect yourself from disputes about timing.

Step 10: Request an Extension If Needed
Contact the IRS examiner before your deadline expires if you are unable to gather all the requested documents in time to request additional time. Submit your extension request in writing and retain the confirmation, as the IRS may grant 10 to 30 extra days if you request it before the original deadline passes.

Always submit copies and keep originals with your permanent tax records, unless the IRS specifically requires originals for verification of financial statements or compliance with financial reporting requirements.
What Happens If You Do Not Respond
If you fail to respond to an examination letter by the stated deadline, the IRS will typically issue a 30-day letter proposing adjustments and offering you the right to appeal under established auditing standards. If you do not respond to the 30-day letter or reach an agreement with an
Appeals Officer, the governmental agency then issues a Notice of Deficiency, giving you 90 days to petition the Tax Court.
While audit reconsideration exists for reopening closed cases with new information and audit support, responding on time provides significantly better outcomes and more negotiating power during both office audit and field audit proceedings with the governmental agency, helping you avoid formal enforcement proceedings.
When Professional Tax Help Becomes Necessary
Certain audit situations require professional legal representation from a law firm to protect your rights and achieve the best possible outcome during office audit or field audit examinations.
Consider hiring legal counsel from a law firm specializing in tax matters when your examination involves complex issues you do not fully understand, technical tax law interpretations beyond basic documentation, or disputes requiring a formal legal opinion.
Professional help becomes critical when the audit covers multiple tax years, examines five or more separate items, involves substantial dollar amounts that could create financial hardship, or when the governmental agency initiates enforcement proceedings. You should seek legal representation immediately if you lack adequate records for items being examined, if your original return contains errors you now recognize, or if the audit inquiry involves potential litigation contingencies.
A law firm specializing in tax matters or legal counsel experienced in IRS enforcement proceedings becomes essential when the governmental agency proposes penalties beyond basic interest charges, requests verification of financial statements, or initiates formal actions under auditing standards.
An enrolled agent, certified public accountant, or tax attorney can provide legal advice, offer a legal opinion on your position, deliver proper audit support during the audit letter process, represent you before the IRS, negotiate on your behalf, and ensure you preserve all appeal rights throughout office audit and field audit examinations while maintaining client confidentiality and adhering to professional auditing standards established by regulatory bodies.
