I got an IRS notice and my books are a mess. Where do I start?

An IRS notice is not an accusation and it is not the start of a criminal matter. Most notices are the automated result of one number on a return not matching a number the IRS received from somebody else. What makes them stressful for a small business owner is not the notice itself. It is the discovery that the records which are supposed to back up the return will not currently do it.

The notice has a response date on it, and that date drives everything else. It is not always immovable: a representative can sometimes request additional time, and for some notice types that is routine. But it is not something to assume, and it is never something to discover you needed on the last day. Treat the printed date as real, and let the person handling the response decide whether more time is worth requesting. The work then happens in a specific order: read what the notice actually asks, get the right professional engaged, and rebuild the records that will answer it.

Most of what the IRS wants is reconstructible. Bank statements, card statements, payroll reports, and invoices exist whether or not anyone entered them into an accounting file. Reconstruction is ordinary work with a known method. It is not a matter of hoping something turns up.

This guide covers the bookkeeping side: how to read what the notice requires of your records, how reconstruction works, and where the line sits between the records work and the tax work. Responding to the IRS on your behalf, taking a position on a return, and representing you in an examination are a different job with different rules, and this article names that boundary rather than blurring it.

Overview

An IRS notice carries a printed response date that does not move because your bookkeeping is behind. Read what the notice specifically asks for, engage a tax professional to handle the response, and rebuild the underlying records from third-party statements and source documents so there is something substantiated to respond with.

What this guide covers

• What the notice is actually asking, and what it is not
• Who does which part, and why the order matters
• Rebuilding records that can answer the question

What the notice is actually asking, and what it is not

The first thing to establish is that a notice is usually specific. It generally identifies a tax year, a form, and an item, and it proposes a change or asks you to substantiate something. Owners tend to read a notice as a judgment on the whole business, which makes the task feel enormous. The actual task is almost always narrower, and knowing how narrow changes what has to be rebuilt.

A large share of notices come from information matching. Third parties report to the IRS: employers file W-2s, clients and platforms file 1099s, banks report interest, brokers report proceeds. When the total the IRS received does not match what appeared on your return, an automated notice follows. That kind of notice is not the result of anyone examining your judgment. It is a mismatch, and the response is either evidence that your figure was right or an agreement that it was not.

This matters for bookkeeping because it tells you where to dig. If the notice concerns unreported income, the reconstruction focuses on deposits: every deposit in the period, categorized, with transfers and loan proceeds and owner contributions separated out from revenue. A great deal of proposed unreported income turns out to be money that was never income, such as a transfer between the owner’s own accounts or a refunded payment.

If instead the notice questions deductions, the work runs the other direction. The IRS position on this is long established: the responsibility to substantiate the entries, deductions, and statements made on a return sits with the taxpayer, and it generally requires documentary evidence such as receipts, canceled checks, or bills. A deduction that is entirely legitimate but undocumented is a much weaker position than the same deduction with a receipt behind it. Certain categories, including travel, vehicle, and gifts, carry strict substantiation requirements where the documentation is effectively the whole case. Elsewhere there is more room for other credible evidence, but that is a matter for your representative to judge rather than something to rely on.

What a notice is not is a verdict. There is a response process, and there is a right to disagree. Those procedural questions belong with whoever represents you, which brings us to the part owners most often get backwards.

• Notices generally name a specific year, form, and item, not the whole business
• Many are automated mismatches against third-party reporting, not examinations
• Income questions are answered by categorizing every deposit in the period
• Deduction questions require documentary evidence, not just a ledger entry
• The response process and any disagreement belong with your representative

Who does which part, and why the order matters

Representation before the IRS is a regulated activity, and the IRS is explicit about who may do it. Among the professionals you would engage, attorneys, certified public accountants, and enrolled agents may represent a taxpayer, authorized through a power of attorney on Form 2848. Form 2848 also covers certain non-practitioners, such as a bona fide officer or full-time employee of the business, which is a separate route from hiring someone. A preparer who is none of those three has far narrower authority, and only if they hold an Annual Filing Season Program Record of Completion, in which case they may represent you on a return they personally prepared and signed, and only before certain IRS employees. For returns prepared after 2015, a preparer holding nothing but a PTIN may prepare returns and may not represent you at all. This is worth knowing before you hand the letter to whoever is nearest.

Bookkeeping is a different function, and the distinction is not a technicality. A bookkeeper reconstructs and reconciles the underlying records: what came in, what went out, what it was for, and whether it ties to the bank. A representative decides what position to take, what to concede, what to contest, and what to file. The records are the input. The position is the output.

The order matters because building records without a strategy wastes the one thing you cannot get more of, which is time before the response date. If your representative intends to concede a small proposed adjustment and contest a larger one, the reconstruction concentrates on the contested item. Rebuilding three years of everything, when the notice concerns one line in one year, is a common and expensive misdirection of effort.

It is worth being direct about AliCat’s own boundary here, because our team includes a CPA and that could easily be read the wrong way. Alicia Hoffman has held a CPA license since 1996. AliCat Solutions is a bookkeeping practice: we do not prepare returns, we do not take positions on returns, and we do not represent clients before the IRS. What we do is rebuild the records so that the professional who does those things is working from something reconciled and complete rather than from a shoebox and an estimate.

In practice that division works well, because the two jobs want different things. Your representative wants a defensible position. Your books need to be right regardless of the outcome. Our guide on bookkeeping cleanup covers what the reconstruction involves and how the scope gets set.

• Attorneys, CPAs, and enrolled agents are the practitioners who may represent you
• A preparer without one of those credentials has narrow authority, or none
• The bookkeeper rebuilds the record; the representative takes the position
• Engage the representative first so reconstruction targets what is contested
• AliCat rebuilds records only, and does not prepare returns or represent clients

Rebuilding records that can answer the question

Reconstruction starts with third-party documents, because those were produced by someone other than you. Bank and credit card statements, payroll reports, loan statements, and merchant processor settlements together describe the movement of money for the period. They are the skeleton, and everything else hangs on them.

The step owners tend to skip is separating the flow of money from the character of money. A statement shows that ten thousand dollars arrived on a Tuesday. It does not show whether that was revenue, a loan advance, a transfer from savings, a customer refund reversal, or the owner putting money in. Those are treated very differently, and the difference is exactly what an unreported income notice turns on. Every deposit in the period needs a determination, and the ones that are not revenue need the document that proves it.

Expenses work the same way in reverse. The statement establishes that a payment happened, and the invoice or receipt establishes what it bought. That pairing is what substantiation means in practice, and it is why a reconstruction that stops at the bank statement leaves the job half done. Where original receipts are genuinely gone, vendors can often reissue invoices and card processors retain transaction detail, so gaps are frequently fillable with a few phone calls.

Retention rules explain how far back this can reach. The IRS frames record retention by purpose rather than by a single number: keep records as long as they are needed to prove the income or deductions on a return. In practice that is tied to the period of limitations for the return in question, which is commonly three years from filing but runs longer in defined circumstances, such as a substantial understatement of income. Employment tax records carry their own clear expectation of at least four years from the date the tax becomes due or is paid, whichever is later. Our guide on how long to keep business records sets out what to hold and for how long.

The final piece is the reconciliation itself. A reconstructed period that ties to the bank, with a clear explanation of how the rebuilt figures relate to what was filed, is a fundamentally different document from a printout of some numbers. One shows its work and can be checked. The other asks to be believed. Given that the burden of substantiation sits with the taxpayer, only the first one is worth producing.

• Third-party statements form the skeleton of any reconstruction
• Every deposit needs a determination, because not all money in is revenue
• Statements prove a payment happened, receipts prove what it was for
• Missing documents are often recoverable from vendors and processors
• The deliverable is a reconciliation that shows its work, not a tidy report

Frequently asked questions

Q: Can a bookkeeper respond to the IRS for me?

A: No. Representation before the IRS is limited to attorneys, certified public accountants, and enrolled agents, authorized through a power of attorney on Form 2848, with narrower authority available to a preparer who holds an Annual Filing Season Program Record of Completion, and then only for a return they personally prepared and signed. A preparer with only a PTIN cannot represent you at all on returns prepared after 2015. A bookkeeper’s role is to reconstruct and reconcile the records that your representative then relies on. AliCat Solutions does bookkeeping only. We do not prepare returns, take positions on returns, or represent clients before the IRS, and we will tell you plainly when something belongs with your CPA or attorney.

Q: My records for that year are genuinely gone. Is that hopeless?

A: Usually not. Very little of what matters exists in only one place. Banks and card issuers retain statement history, payroll providers retain filings and reports, merchant processors retain transaction detail, and vendors can often reissue invoices. A reconstruction assembles the period from those outside sources rather than from whatever survived in your filing cabinet. Where a genuine gap remains after that, the right move is to document what was done to close it, and let your representative decide how to handle what is left.

Q: Should I file an amended return to fix the problem before I respond?

A: Not before your representative has read the notice. An amended return is a specific procedural act with consequences for the matter in progress, and with automated mismatch notices the response process is usually where the correction belongs. Some notices do ask for a particular filing. Which case you are in is exactly what your representative reads the notice to determine. The same applies to reclassifying prior-period transactions in your accounting file. Get current going forward, gather the documents, and let the person handling the response decide what gets filed and when.

Q: How long does a reconstruction take, and will it be done before my deadline?

A: It depends on how much of the period is unreconciled and how narrow the notice is, which is why identifying the specific item in question comes first. A single contested year with intact bank records is a matter of weeks. Several years with missing statements takes longer, because the first task is requesting documents from third parties and waiting for them. If the timeline is genuinely tight, that is a conversation for your representative, since extensions of time to respond are a procedural question rather than a bookkeeping one.
