1. Identify the Scope of the IRS Records Request
Begin with the IRS request and the return under examination. Confirm the taxpayer, tax periods, requested items, and response instructions before gathering files. This article addresses federal income tax examinations involving business activity. State tax audits and separate employment tax examinations follow different requirements.
Confirm the Taxpayer, Return, and Tax Period
Check the name and taxpayer identification number against the return. A sole proprietor reports business activity on an individual return, while a corporation generally files separately. The business’s tax classification determines which return and records matter. Read the response deadline in the notice or Information Document Request, which may appear on Form 4564. If you need additional time, contact the identified IRS employee before the deadline and document any agreed extension.
Map Each Requested Item to the Return and Ledger
Give each requested item a reference number and connect it to the relevant return line, ledger account, and supporting files. Start with the return as filed and identify any later amendments. Preserve the accounting reports and adjustments used to prepare those filings, since a current ledger may contain subsequent changes. For an IRS audit, the reconciliation should let the examiner follow the calculation from the reported figure to individual transactions.
2. Reconcile Reported Receipts with Sales and Bank Records
Bank deposits do not necessarily equal taxable business receipts. Sales reports, processor statements, and bank records capture different stages of a transaction. Before treating a difference as an error, check the accounting method used on the return and whether the records cover the same period.
Compare Sales Records, Payment Reports, and Deposits
Compare invoices or point-of-sale totals with payment processor reports and bank deposits. Processor payouts may be reduced by fees, refunds, or chargebacks, while information returns may report gross payments. Identify how each amount entered the books so that the reconciliation does not count receipts twice or deduct the same fee twice. Include cash sales even when the business used the cash directly rather than depositing it. An unexplained difference calls for investigation; it does not establish omitted income by itself.
Explain Transfers, Loan Proceeds, and Timing Differences
Transfers between accounts belonging to the same taxpayer generally do not create additional income. Genuine loan proceeds also generally differ from sales receipts. Match transfers to both account statements and borrowing to loan documents and disbursement records. Separate those transactions from amounts whose treatment remains uncertain. For timing differences, record the invoice date, payment date, and accounting treatment. A year-end invoice’s date alone does not determine when the income must be reported.
3. Connect Claimed Expenses to Supporting Evidence
An expense entry shows how the business classified a transaction, but it does not establish that the deduction is allowable. Supporting evidence should identify what the business purchased, the amount, the business purpose, and the proper tax year. The type of expense determines whether additional substantiation is required.
Match Ledger Entries with Invoices and Payment Records
Connect each questioned expense to an invoice or receipt, payment evidence, and its business purpose. A bank statement may show that money left the account without explaining what the payment covered. Identify personal portions, reimbursements, and duplicate entries where relevant. Equipment purchases may require capitalization and depreciation analysis rather than a current deduction. When examining wage expenses, compare payroll registers with the reported deduction and identify relevant adjustments. That comparison does not, by itself, resolve separate payroll tax obligations.
Identify Missing Records and Limits on Reconstruction
Request replacement invoices, statements, contracts, or other reliable evidence when records are missing. If you prepare a reconstruction, label it accordingly and explain which documents support it. Preserve the original records and keep later explanations separate from notes created at the time of the transaction. Certain expenses, including travel and vehicle use, have specific substantiation requirements that unsupported estimates cannot satisfy. Whether alternative evidence is sufficient depends on the expense and why the original records are unavailable.
4. Track Submissions and Resolve Follow-Up Requests
A submission record helps distinguish unanswered requests from questions the business has already addressed. Retain the original documents, an exact copy of each response, and evidence of delivery. Follow the IRS instructions for submitting records, and send copies rather than mailing originals.
Maintain an Itemized Submission and Contact Log
Create an index connecting each request number to the submitted files and relevant pages. Record submission dates, delivery confirmations, follow-up requests, and substantive conversations with the examiner. After a call, note the date, participants, and any agreed next steps. If a later response corrects an earlier explanation, identify the correction and its reason. The following table offers a working format; it is not an IRS-required form.
| Tracking Field | What to Record |
|---|---|
| Request reference | Item number, tax period, and response deadline |
| Reported figure | Return line and amount under examination |
| Accounting support | Ledger account, transactions, and adjustments |
| Supporting evidence | Submitted file names and relevant pages |
| Submission history | Delivery date, confirmation, and later corrections |
| Open question | Missing evidence, unexplained amount, or disputed treatment |

Separate Unresolved Facts from Tax Treatment Disputes
A missing invoice raises an evidence issue. A disagreement over whether a documented purchase must be capitalized raises a tax treatment issue. Before responding to a proposed adjustment, identify which transaction, amount, or treatment the examiner challenges. A business tax lawyer can review the legal issue while the accountant explains the underlying entries and calculations. If the examination develops into an IRS business tax dispute, later notices may carry separate response or filing deadlines. Continuing to send documents does not extend those deadlines. Further review of tax disputes should therefore begin with the specific notice and the issue that remains unresolved.
