A field audit represents the most detailed and rigorous form of tax examination conducted by the Internal Revenue Service (IRS). Unlike other types of audits that might be handled through correspondence or at a local IRS office, a field audit involves an IRS revenue agent visiting your home, place of business, or accountant’s office to inspect your financial records and operations firsthand. This on-site interaction allows the IRS to dive deeply into your financial affairs to verify the accuracy of your tax return and ensure complete compliance with tax laws.
How Does a Field Audit Work?
The process begins when you receive an official notice, usually a certified letter such as a CP2000 or similar IRS communication. This letter informs you that your tax return for specific year(s) has been selected for audit and outlines the subjects or issues the IRS intends to review. It’s critical to respond promptly and not ignore this notice, as non-response can lead to enforced tax assessments and penalties.
Once the audit is scheduled, the IRS agent typically sends an Information Document Request (IDR) detailing the specific documents needed, including bank statements, invoices, receipts, payroll reports, mileage logs, and other relevant financial records. The IRS prefers to conduct the audit either at your business location, your home if you are a sole proprietor with business operations there, or your accountant’s office — the latter often offering a more controlled and professional environment.
During the on-site examination, the IRS agent thoroughly reviews the submitted documents, asks clarifying questions, and may observe your business operations or interview employees if pertinent. The duration of a field audit can range from several days to weeks or even months depending on the complexity of your financial situation.
Following the review, the auditor discusses findings with you or your representative. Proposed adjustments to your tax return will be explained. You may agree, resulting in signing an agreement form for additional tax payment or refund, or disagree, triggering avenues such as an appeals process or tax court proceedings.
Who is Likely to Receive a Field Audit?
While any taxpayer can be audited, the IRS typically targets returns with complex financial activities or significant discrepancies. The IRS utilizes various methods to select returns, including:
- Computer Screening: The Discriminant Information Function (DIF) system assigns a score based on the likelihood of underreporting or errors, flagging high-risk returns.
- Information Matching: Discrepancies between third-party reports (e.g., W-2s, 1099s) and your tax return can trigger audits.
- Related Examinations: If associates or business partners are audited and transactions overlap, your return may also be scrutinized.
- Random Selection: To maintain compliance and fairness, some returns are randomly chosen.
- Industry or Issue Targeting: Certain industries or tax issues may be specifically targeted in a tax year.
Certain return characteristics that often lead to field audits include high income, large deductions relative to income, foreign transactions, or suspicion of fraudulent activities. IRS Publication 1, “Your Rights as a Taxpayer,” explains selected procedures for examinations (see IRS Publication 1).

Preparing for and Managing a Field Audit
Receiving a field audit notice can be stressful, but proper preparation is essential for a positive outcome:
