Illustrative. An example of the document, not a client's figures.
A correspondence audit arrives by mail, not as a visit or a phone call, and usually focuses on one or two specific items on a return rather than the whole thing, a home office deduction, a charitable contribution, a claimed credit. It is narrower than an in-person examination, but the letter is still a real audit with a real deadline, and an unanswered one can turn a routine question into an assessed balance simply because nobody responded in time.
The first step is reading the letter for what it is actually asking, not what it sounds like it is asking. IRS correspondence letters sometimes read broader in tone than the specific documentation they require, and responding to the tone instead of the actual request means sending either too little, which invites a follow-up letter, or far too much, which slows down a reviewer and can surface unrelated questions nobody needed to raise. We match the letter against the specific code section or line item it cites and confirm exactly what would satisfy that request before pulling a single document.
Once the scope is clear, we go back into your books, bank and card statements, and prior filings to pull the receipts, invoices, mileage logs, or contribution acknowledgments the letter is asking for. Each document gets indexed against the specific item under review, so a reviewer opening the package can trace every dollar claimed on the return back to a specific piece of support without hunting through an unsorted folder of scanned receipts. That indexing is often the difference between a package that gets accepted on the first pass and one that comes back with a follow-up request simply because the reviewer could not tell what supported what.
We flag gaps honestly and early, while there is still time to do something about them, rather than discovering a missing receipt the week the response is due. Sometimes a gap can be filled from a bank or card statement reconstructing the transaction even without the original receipt. Sometimes it genuinely cannot be filled, and in that case we say so plainly rather than manufacturing documentation after the fact, and help identify whether a reasonable alternative explanation exists that a reviewer might actually accept.
What we do not do is talk to the examiner directly beyond submitting the finished package, and we do not perform anything resembling a financial-statement audit of your business. Any direct communication with the IRS beyond that submission, including a follow-up call or a request to extend the deadline, is handled by our enrolled agent or CPA partner under a Form 2848 you sign, consistent with Circular 230, the rules that govern who can practice before the IRS.
What is included
The engagement covers a line-by-line read of the audit letter against the specific code section, credit, or deduction it questions, so the response addresses exactly what is being asked rather than everything on the return. We pull supporting receipts, statements, invoices, mileage logs, or acknowledgment letters from your books, bank and card records, and prior filings, then index every document against the specific line item it supports. Where the letter raises more than one issue, each gets its own labeled section in the finished package rather than one undifferentiated pile of documents. The completed, indexed package, along with a short cover memo explaining what each section addresses, goes to our enrolled agent or CPA partner for review and submission.
How the process works
We start with the letter itself, confirming the deadline and matching each specific request against the exact form or schedule item it references, since correspondence letters cite specific lines rather than describing the issue in plain language. From there we go through your existing records, QuickBooks Online, Xero, or Dext where receipts are already captured, and pull what already exists before deciding what needs to be reconstructed from bank or card statements. Documents get indexed as they come in, tagged to the specific item they support, so the package builds itself as an organized response rather than a last-minute scramble against the deadline. Once assembled, the package and a short summary memo go to our enrolled agent or CPA partner, who reviews it, requests anything additional needed, and handles submission and any examiner contact from that point forward.
Who this is for
This fits any business or individual who received an IRS letter questioning a specific item, a home office deduction, mileage, a charitable contribution, a business expense category, rather than a full examination of the entire return. It particularly fits a business whose records exist but are scattered across bank statements, a receipt-capture app, and a shoebox of paper, since the value of this engagement is largely in the organizing and matching, not in creating documentation that does not exist. It is not the right service for a full field examination covering multiple years and multiple issues, which typically needs broader representation from our enrolled agent or CPA partner well beyond assembling one document package.
Common problems we fix
The most common problem is responding to the tone of the letter instead of its specific request, which usually means sending far more or far less documentation than the letter actually calls for. The second is an unsorted pile of receipts and statements handed over with no index, which slows down a reviewer and increases the odds of a follow-up letter simply because nothing is clearly matched to the item it supports. The third is a genuine documentation gap discovered the week the response is due, with no time left to reconstruct it from bank records or identify an alternative. The fourth is missing the response deadline entirely because the letter's stated timeframe was not confirmed against the actual postmark and any extension already granted.
Software and integrations
We pull existing bookkeeping records from QuickBooks Online or Xero to trace the deduction or credit in question back to its original entry, and use Dext where receipts were already captured through a receipt-scanning workflow, which often shortens the documentation-gathering step considerably. Bank and card statements come through directly from the bank when a receipt does not exist, and Adobe Acrobat handles the final indexing and assembly of the package into one organized, paginated document our enrolled agent or CPA partner can review and submit as a single file.
What it costs
Correspondence audit document pack preparation is quoted as a standalone project, priced by how many items the letter raises and how much of the supporting documentation already exists in your books versus needs reconstruction, separate from the monthly bookkeeping tiers on the rate card. A single-item letter with clean existing records is a much smaller scope than a letter raising several issues across a year with thin documentation. We quote a fixed price after reading the actual letter, before starting the document pull.
How we measure quality
The measure that matters is whether the package resolves the letter on the first submission, without a follow-up request for additional documentation that restarts the deadline clock and extends how long the matter stays open. We track that outcome for every case, and where a gap genuinely cannot be filled, we measure success by whether we flagged it early enough for you and our partner to plan around it, rather than by pretending every letter closes cleanly.
Reading the letter correctly, before pulling anything
The single biggest driver of how smoothly a correspondence audit resolves is getting the scope right at the start. A CP2000-type notice questioning unreported income is a different animal from an examination letter questioning a specific Schedule C deduction, and each cites specific figures or line items that tell you exactly what needs supporting, if you read past the boilerplate language at the top of the letter. We treat that first read as its own step, not something to skim on the way to pulling documents, because a wrong assumption about scope at the start means either wasted work gathering documentation nobody asked for, or a response that misses what the letter actually needed and comes back with a second, harder round.
How we work
The process
- 1
Letter review against actual scope
We read the audit letter line by line, confirm the deadline, and match each request against the specific form line or credit it questions.
- 2
Records pull from existing bookkeeping
We pull whatever supporting documentation already exists in QuickBooks Online, Xero, or a receipt-capture tool before reconstructing anything.
- 3
Gap identification
Any item the letter requests that is not already documented gets flagged early, with a plan to reconstruct it from bank records or explain it.
- 4
Document indexing
Each receipt, statement, or workpaper is indexed against the specific line item it supports, organized into a single package by issue.
- 5
Cover memo and internal review
A short memo summarizing what each section addresses accompanies the package before it goes to our enrolled agent or CPA partner.
- 6
Submission and examiner contact
Our enrolled agent or CPA partner reviews, finalizes, and submits the package, and handles any direct examiner contact from that point on.

Common problems we fix
The problem
How we fix it
- Response built around the letter's tone instead of its specific requestWe match each request to the exact line item or code section it cites, so the package answers what was actually asked.
- Documentation handed over as an unsorted pile of receiptsWe index every document to the specific item it supports, so a reviewer can trace each figure without a follow-up request.
- A documentation gap discovered the week the response is dueWe review the full request against existing records early, so any real gap surfaces with enough time to reconstruct or address it.
- The response deadline missed or miscalculatedWe confirm the actual deadline against the letter's postmark and any extension already granted, rather than assuming from the letter's printed date.
Pricing

Questions
Frequently asked questions: IRS correspondence audit document packs
What is a correspondence audit?
An IRS examination conducted entirely by mail, usually focused on one or two specific items on a return, such as a deduction or a credit, rather than the whole return.
Is a correspondence audit the same as a full IRS audit?
It is narrower in scope than an in-person examination, but it is still a real audit with real deadlines, and an unanswered letter can turn a routine question into an assessed balance.
Do you represent me in the audit itself?
We assemble and organize the documentation. Any direct communication with the examiner beyond submitting the finished package is handled by our enrolled agent or CPA partner under a signed Form 2848.
What if I am missing some of the requested documentation?
We work with what exists, including bank and card records reconstructed from your books, and flag honestly to you and our partner where a genuine gap cannot be filled.
How long do I have to respond to a correspondence audit letter?
The letter states a specific deadline, commonly around 30 days, though it varies by notice type. We confirm the actual date against the letter's postmark first, since assuming from the printed date alone can be wrong.
What happens if I miss the response deadline?
The IRS can proceed to assess the disputed item as if it were correct, turning a documentation question into a real balance due. If a deadline is close or already passed, tell us immediately so our partner can request whatever relief may still be available.
Can this turn into a bigger examination if the reviewer does not like the answer?
It can, though it is uncommon for a narrow correspondence audit to expand significantly. We build the package to answer exactly what was asked accurately, which is the best way to keep the matter from growing beyond its original scope.
Do you also help if the audit is about unreported income rather than a deduction?
Yes. A CP2000-type notice about unreported income gets the same line-by-line review and document assembly, matched against whatever income document the IRS says is missing, along with our IRS notice review service where a broader notice response is also needed.
