An IRS audit, also called an examination, is a review of a tax return and related financial information to determine whether the reported information is accurate and complies with applicable tax rules.
An audit does not automatically mean that a taxpayer made a mistake. The IRS may select returns for different reasons, and an examination can result in no change, an agreed adjustment, or a disputed adjustment.
The IRS may conduct an audit through correspondence, at an IRS office, or in other settings depending on the circumstances.
An audit may involve reviewing:
Income reported on a tax return
Deductions
Credits
Business expenses
Investment transactions
Supporting documentation
Other relevant financial information
The IRS generally provides instructions explaining what information is being requested and how the taxpayer should respond.
An IRS notice may request documentation or explain a proposed change to a tax return.
Taxpayers should review:
| Notice Information | Why It Matters |
| Tax Year | Identifies the return being reviewed |
| Issue | Explains the subject of the notice |
| Requested Documents | Identifies information to provide |
| Response Deadline | Indicates when action may be required |
| IRS Contact Information | Provides the appropriate communication channel |
| Proposed Adjustment | Explains a potential change where applicable |
Keeping the original notice is important for maintaining an accurate audit record.
Appropriate documentation depends on the issue being examined.
Records may include:
W-2 or other income statements
1099 forms
Bank statements
Receipts
Invoices
Investment records
Property records
Business expense documentation
Charitable contribution records
Prior tax returns
Taxpayers should provide information that is relevant to the IRS request and retain copies of submitted documents.
A structured response can help taxpayers manage the process.
Generally, taxpayers should:
Read the IRS notice carefully.
Identify the specific tax year and issue.
Gather relevant records.
Compare the records with the filed return.
Respond by the stated deadline.
Keep copies of correspondence and documents.
Seek professional guidance when the matter is complex.
The appropriate response depends on the specific audit and IRS instructions.
A taxpayer may disagree with an IRS proposed adjustment.
Depending on the circumstances, taxpayers may have options to:
Provide additional documentation
Explain the disputed position
Request reconsideration where applicable
Pursue an administrative appeal
Seek judicial review when available
Appeal rights and deadlines vary according to the type of tax matter.
Taxpayers have rights when dealing with the IRS, including the right to:
Receive information about the process

Understanding these rights can help taxpayers communicate more effectively during an examination.

Taxpayers can strengthen compliance by:
Reporting income accurately
Keeping supporting records
Reviewing deductions carefully
Maintaining copies of filed returns
Tracking investment and property transactions

A qualified tax professional can help explain the applicable process and organize a response.

Not necessarily. An audit does not automatically establish an error or violation. The examination may result in no change or in proposed adjustments depending on the findings.

In certain circumstances, taxpayers can challenge proposed adjustments through administrative procedures and, where available, further review. The applicable deadlines and procedures depend on the matter.
Recordkeeping periods can vary according to the document, transaction, and applicable tax rules. Taxpayers should review current IRS guidance for the specific records involved.
