When an IRS auditor asks for bank statements, the request is rarely incidental. It is one of the clearest signals that the audit has moved beyond surface-level review and into financial verification. Bank statements are not requested to “double-check” arithmetic; they are requested because the IRS is testing whether the tax return accurately reflects economic reality.
Many taxpayers assume the request means the IRS believes income was underreported. Sometimes that is true. In other cases, the IRS is testing deductions, lifestyle consistency, commingling of funds, or overall credibility. Regardless of the underlying concern, a bank-statement request marks a turning point in the audit.

Bank Statements Are One of the IRS’s Most Reliable Audit Tools
From the IRS’s perspective, bank statements are one of the most reliable third-party records available during an audit. Unlike receipts, spreadsheets, or bookkeeping software—which are created or controlled by the taxpayer—bank statements originate from independent financial institutions.
IRS examiners are trained under IRM 4.10 to evaluate the credibility of taxpayer-provided records. When those records appear incomplete, inconsistent, or overly curated, the examiner looks for an external benchmark. Bank statements serve that role.
By reviewing deposits, withdrawals, transfers, and balances, the IRS gains insight into how money actually moved—not how it was later categorized.

The IRS Requests Bank Statements to Verify Reported Income
One of the primary reasons bank statements are requested during an audit is to verify whether reported income aligns with actual cash flow. The IRS understands that income can be understated intentionally or unintentionally, particularly when income is derived from multiple sources or paid outside traditional payroll systems. Bank statements allow examiners to compare deposits against income reported on Forms W-2, 1099-NEC, 1099-K, K-1s, and Schedule C.

Bank Statements Are Used to Test the Credibility of Deductions
Even when income is not the primary concern, the IRS frequently requests bank statements to test whether claimed deductions are economically plausible. Deductions reduce tax liability directly, and inflated or personal expenses are common audit issues.
By reviewing withdrawals and expenditures, examiners assess whether expenses claimed on the return actually appear in financial records. If deductions for advertising, travel, meals, or supplies are claimed, but corresponding payments do not appear on bank statements, the IRS may question whether those expenses were incurred at all.

The IRS Uses Bank Statements to Identify Commingling
Another major reason bank statements are requested is to detect commingling of personal and business funds. Commingling complicates substantiation and often undermines the taxpayer’s credibility.
When personal and business transactions flow through the same account, the IRS may conclude that expense allocations are unreliable or that income was diverted or mischaracterized. This is particularly problematic for Schedule C filers and closely held businesses.
Commingling does not automatically imply fraud, but it often leads to expanded examination and increased use of indirect methods to determine income.

Bank Statements Are Requested When Records Appear Incomplete
IRS examiners are trained to evaluate the quality of records, not just their existence. When bookkeeping files appear incomplete, selectively produced, or internally inconsistent, examiners often request bank statements to fill perceived gaps. From the IRS’s standpoint, missing or weak records justify reliance on independent bank data.
What It Signals Internally When the IRS Requests Bank Statements?
Internally, a request for bank statements often reflects an examiner’s conclusion that the audit cannot be resolved based solely on taxpayer-provided documentation. It does not automatically mean the examiner believes fraud occurred—but it does mean the examiner believes verification is necessary.
When to Hire a Tax Attorney?
