An IRS audit notice can feel more serious than it is because the process depends heavily on how the IRS selected your return and what it needs to verify. A letter requesting specific records is handled differently from an examination that takes place through scheduled conversations and a broader review of your tax information.
In an irs field audit vs correspondence audit, the central difference is setting and scope: a correspondence audit generally asks you to send documents by mail or through an approved submission method. A field audit is conducted in person, often at your home, business, or representative’s office. The notice should explain the issues under review and the records requested. The Taxpayer Advocate Service explains that responding carefully and keeping copies of what you submit can help you manage either process.

Understanding where the audit happens is only the starting point. The documents requested, meeting expectations, response deadlines, taxpayer rights, and available representation can all differ, so the next step is to compare how each examination works in practice.
What to Know About an IRS Field Audit vs Correspondence Audit
In an IRS field audit vs correspondence audit, the main difference is how the IRS conducts the examination. A correspondence audit takes place through written communication, while a field audit is conducted in person. The IRS Taxpayer Advocate Service explains that audits generally occur either by mail or in person. Learn more about audits by mail from the Taxpayer Advocate Service.
A correspondence audit is usually limited to specific items on a return. The IRS may ask you to provide records or explanations by mail, and the review stays focused on the issues identified in the notice. The IRS describes this type of examination as relatively limited in scope. That does not mean the notice should be ignored or treated casually. The requested information and response instructions control how you should proceed.
A field audit involves an in-person examination. The initial contact may set an appointment for an IRS examiner to visit the relevant premises, rather than simply requesting records by mail. The meeting can involve questions about the return and supporting records, with the scope depending on the facts under review. An in-person format does not automatically mean the taxpayer did something wrong. The Taxpayer Advocate Service notes that being selected for an audit does not, by itself, establish that something is wrong. Read the Taxpayer Advocate Service overview of audit selection and mail audits.
These categories are not always permanent. A correspondence audit can expand into an in-person field audit when the issues become more complex or the taxpayer does not respond, according to the IRS. That possibility makes it important to read the notice carefully, preserve relevant records, and respond through the channel and by the deadline stated. The format of the audit may change, but the notice remains the starting point for understanding what the IRS is examining.
How a Correspondence Audit Works
A correspondence audit is a limited-scope IRS examination handled primarily through letters and document submissions. The process is guided by the notice you receive, so read it carefully before sending anything. This correspondence-audit guide provides additional background, but the IRS notice controls the specific request in your case.
- Review what the notice identifies. The letter should explain which items on the return are under review, what documentation the IRS needs, where to send it, and whom to contact with questions. It should also explain how to proceed. An audit selection does not automatically mean the return contains an error. The Taxpayer Advocate Service explains the audit-by-mail process and the information typically included in the request.
- Gather only relevant support. Match your records to the items listed in the notice. Make clear, readable copies, and keep the originals. The Taxpayer Advocate Service specifically advises taxpayers not to send original documents. Keep a complete copy of everything submitted, including the letter and any cover explanation.
- Submit the response by the stated due date. Send the requested documentation to the address in the audit letter and follow any instructions about labeling or organizing the materials. Do not assume that a standard deadline applies to every audit. If the notice offers the IRS Document Upload Tool, digital submission may be available. Use the upload option only when the notice indicates it, and follow its instructions, including any notice-specific QR code. The Taxpayer Advocate Service describes these digital submission options.
- Wait for the IRS review and respond to follow-up. After the initial review, the IRS may accept the return as filed, request more information, or propose changes. A correspondence audit can become an in-person field audit if the issues grow more complex or the taxpayer does not respond. The possible outcome depends on the records, facts, and issues identified in the examination. The IRS describes the limited scope and possible expansion of correspondence audits.
Do not ignore a notice or send unrelated records in hopes of resolving the matter faster. If the request is unclear or the records are incomplete, consider obtaining qualified tax assistance before responding.
What Happens During an IRS Field Audit
A field audit is an in-person examination of selected items on a tax return. The meeting does not necessarily take place at an IRS building. Depending on the circumstances, the examination may occur at your home, your business, an IRS office, or the office of an attorney, accountant, or enrolled agent. For official information about examination procedures, review the IRS and Taxpayer Advocate Service guidance linked below.
The notice and initial meeting
Before the appointment, read the IRS notice carefully. It should identify the part of the return under examination, the information you need to provide, and other details about the audit. An appointment confirmation may also include Form 4564, Information Document Request. If included, that form lists documents and information to bring to the scheduled appointment.
The first meeting may begin with an interview. The examiner can ask about your financial history, business operations, and books and records that are not available from other sources. Answer questions accurately and stay within the scope of the notice. If the appointment is inconvenient, contact the examiner before the proposed date to discuss rescheduling rather than ignoring the notice.
What can happen at a business
When a business is being audited, the examiner may ask to tour the business. The purpose is to better understand how the operation works and how the reported income, expenses, assets, or other return items relate to that operation. A tour is not proof that the IRS has concluded there was wrongdoing. It is one way the examiner may gather context that is not apparent from documents alone.
Follow-up requests and next steps
A field audit can involve more than one conversation or document exchange. If the examiner needs additional information after the meeting, the request should be made in writing. Keep copies of everything you provide and track each request separately so you can respond to the correct item.
Unlike a limited correspondence review, a field examination gives the IRS an opportunity to discuss records and operations in person. If you are unsure how to respond, you can ask the examiner questions about how the examination is being conducted. You may also pause an interview to obtain professional assistance or speak with your representative. An authorized practitioner can communicate with the IRS after the appropriate power-of-attorney process.
For official guidance, review the Taxpayer Advocate Service information on in-person audits and the IRS appointment-confirmation guidance on Form 4564 and requested records.
IRS Audit Types Compared: Location, Scope, and Records
The IRS generally conducts audits by mail or in person. The notice format gives an early clue about the examination. A correspondence audit asks you to provide documents, while a field examination involves an appointment and may include an IRS representative reviewing information with you or your representative. The Taxpayer Advocate Service explains audits by mail, and its in-person audit guidance describes the other format.
| Comparison point | Correspondence audit | Field audit |
|---|---|---|
| Setting | Handled remotely through letters and, when applicable, phone calls or an IRS document-upload process identified by the notice. | Conducted in person at a home, business, IRS office, or the office of an authorized representative. |
| Typical scope | Relatively limited, focused on specific return items identified in the correspondence. | May involve a broader review of financial history, business operations, and books and records. A business visit may help the examiner understand how it operates. |
| Contact method | The notice explains what to provide, where to send it, and who to contact. The agent may continue through letters and phone calls. | The notice or appointment confirmation identifies the examination area, meeting details, and information to bring. Additional requests should be made in writing. |
| Records | Send copies of the requested records by the stated due date and to the address in the letter. Keep the originals and a complete copy of your response. | Bring the records listed in the notice or any Form 4564, Information Document Request. Organize supporting books and records so the examiner can connect them to the items under review. |
| Practical preparation | Read the notice closely, answer only the identified requests, meet the deadline, and retain proof of submission. | Review the requested items before the appointment, prepare to explain relevant records and operations, and consider professional assistance if the facts are complex. |
These categories are not always permanent. The IRS states that a correspondence audit can become an in-person field audit when issues grow more complex or the taxpayer does not respond. That makes a clear, timely response important even when the first notice appears narrow. The IRS correspondence-audit guidance provides that scope distinction.

What Timeline and Taxpayer Rights Should You Expect?
There is no universal number of days for an IRS audit. The timing depends on the notice, the records requested, the complexity of the issues, how quickly information is exchanged, and whether the examination expands. The IRS describes the audit process as beginning with initial contact and continuing until a closing letter is issued. For a broader stage-by-stage overview, see this IRS audit timeline.
Start with the notice
The audit notice should explain why the return is being examined, which documents may be needed, and how to proceed. Read it carefully before responding. A correspondence audit may ask you to send copies of specific records. A field-audit notice may identify an appointment, the part of the return under review, and information to bring. The Taxpayer Advocate Service explains that an in-person notice may include Form 4564, an Information Document Request, listing requested documents.
Use the response method and deadline stated in the notice. Keep copies of everything you submit and proof of delivery or upload. If the request is unclear, contact the examiner using the information provided instead of guessing about what to send.
Appointments and questions
If a proposed in-person appointment is inconvenient, contact the examiner before the appointment to discuss rescheduling. Rescheduling is not a guarantee that the examination will pause indefinitely, so make the request promptly and continue following the notice instructions.
You may ask the examiner questions about how the examination is being conducted. If you need further clarification, you can ask to speak with the examiner’s manager. During an in-person interview, you may also pause the interview if you want to obtain professional assistance or speak with your representative. The Taxpayer Advocate Service’s in-person audit guidance explains how the process may work and where to find additional taxpayer assistance.
Closing the examination
After reviewing the information, the IRS may accept the return, request additional support, or propose changes. A field examination can involve written follow-up requests, and a correspondence audit can become more extensive if issues grow complex or the taxpayer does not respond. The final result should be documented through the IRS’s closing process. Keep the notice, correspondence, records, and any closing letter together for your files.
General information cannot predict the duration or outcome of a specific examination. If the issues are complex, the requested records are extensive, or you are unsure how to respond, consider obtaining advice before the next communication with the IRS.
When Should You Consider Professional Tax Help?
Professional assistance from an attorney, certified public accountant, enrolled agent, or other qualified practitioner may be worth considering when an audit feels difficult to manage, the issues are technical, or you would prefer help communicating with the IRS. It may also help when an in-person examination involves detailed questions about your financial history, business operations, books, or records. You do not have to wait for the audit to become overwhelming before asking about your options.
The right time to seek help depends on your circumstances. Consider speaking with a qualified professional if you are unsure what the notice requests or are concerned about explaining complex transactions. Guidance may also help if you are struggling to organize supporting records or feel uncomfortable answering questions without assistance. A taxpayer who meets the requirements may also qualify for help from a Low Income Taxpayer Clinic. Ask any professional about the services offered, scope, and fees before agreeing to assistance.
What Does Form 2848 Do?
If you want someone to represent you at an examination appointment, the IRS identifies Form 2848, Power of Attorney and Declaration of Representative, as the form used to authorize that relationship. Form 2848 is not a promise that the IRS will accept a position or change the audit. It establishes the authority for an eligible representative to act within the scope stated on the form.
Once the appropriate power-of-attorney process is completed, an authorized practitioner may communicate with the IRS for you. Representation can include preparing for questions, reviewing requested information, helping organize a response, and participating in communications or meetings as permitted. IRS materials also identify representation and Form 2848 among taxpayer-rights information, along with appeal rights and procedures.
Professional assistance cannot guarantee acceptance of your return, a reduced tax liability, a particular audit result, or a specific timeline. The IRS makes its own decisions after reviewing the facts and supporting information. A representative can help you respond carefully and understand the process, but no responsible professional can promise the outcome.
How to Prepare for an IRS Field Audit vs Correspondence Audit
Being selected for an audit does not automatically mean the IRS found an error. Reviewing why the IRS selects returns can provide useful context, but the immediate priority is responding carefully to the notice.
Use the notice as your preparation checklist
Read the entire notice before gathering records. It should identify the return items under review, the documents or information the IRS wants, where to send them, and whom to contact with questions. A field-audit notice may also identify an appointment and include Form 4564, an Information Document Request, listing records to bring. Do not assume that a general tax-history file answers every request.
- Identify the scope: Note the tax year, issues, records requested, submission method, and response deadline.
- Organize relevant support: Group receipts, statements, logs, contracts, and other records by the return item they support. Include a brief explanation when a document may not be self-explanatory.
- Send only requested support: Provide copies rather than original documents. If the notice offers a digital upload option, use the submission method and instructions stated in that notice.
- Keep a complete copy: Save the notice, every document submitted, your explanations, proof of delivery or upload, and notes about communications.
- Meet the stated deadline: Send the response to the address or system identified by the IRS. If you cannot comply, contact the listed examiner or representative promptly rather than ignoring the request.
Complex business records, multiple tax years, missing documentation, or uncertainty about what a request means may justify professional guidance. An authorized practitioner can help organize the response and communicate with the IRS after the appropriate authorization process. For broader information, review the Taxpayer Advocate Service’s in-person audit guidance. Careful preparation can support a clear response, but it cannot guarantee that the IRS will accept every item or reach a particular result.
Frequently Asked Questions
What happens if you get audited and do not have receipts?
Gather any available records that support the item, such as bank statements, invoices, mileage logs, or other contemporaneous evidence. Send copies rather than originals, and explain gaps honestly. The IRS may adjust an unsupported item, so professional help can be useful when records are incomplete. The Taxpayer Advocate Service explains document responses.
How many years can the IRS go back for an audit?
The answer depends on the facts, the return, and the applicable limitation rules. Do not assume that every audit covers the same number of years. Read the notice carefully to see which tax period and return items are identified. Then ask the examiner or a qualified tax professional what additional periods, if any, are relevant.
Can a correspondence audit become a field audit?
Yes. A correspondence audit is generally limited in scope. But the IRS says it can expand into an in-person field audit when issues become more complex or the taxpayer does not respond. Meet the notice deadline, provide the requested support, and keep copies of everything submitted. See the IRS description of correspondence audits.
What should I do first after receiving an audit notice?
Confirm the tax year, issues under review, response deadline, submission method, and IRS contact information. Organize only the records relevant to the notice, submit copies by the stated deadline, and retain proof of delivery. If the issues are complex or an in-person interview is scheduled, consider consulting an authorized representative before responding.
