How Long Does A Tax Audit Take?

If you have received an IRS audit notice, one of the first questions you probably have is: how long is this going to take? The honest answer is that it depends — on the type of audit, the complexity of your return, how well-documented your records are, and whether you have professional representation.

At Tsamutalis & Company, we handle IRS audit representation for small businesses and individuals throughout Bergen County and Northern New Jersey. Here is what you need to know about the audit process and its typical timeline.

The Three Main Types of IRS Audits

Not all audits are the same. Understanding which type you are facing shapes everything about how long the process takes.

Correspondence Audits

The most common type. The IRS sends a letter requesting documentation for a specific item on your return — a deduction, a credit, a reported income figure. You respond by mail with the supporting documentation. These are typically resolved in a few weeks to a few months, depending on how quickly you respond and whether the IRS requests additional information.

For many small business owners, a correspondence audit is triggered by a mismatch between what was reported on the return and what was reported to the IRS on a 1099 or W-2. Responding promptly with clean documentation usually resolves these quickly.

Office Audits

An office audit requires you to appear in person at a local IRS office with your records. These are more involved than correspondence audits and typically cover several items on your return. Office audits usually take a few months to resolve from the initial appointment through final determination, though the timeline can extend if the IRS requests additional documentation or if there are disagreements about specific items.

Field Audits

The most comprehensive type. An IRS agent comes to your home or place of business to review your records in person. Field audits are typically reserved for complex returns or situations where the IRS has significant concerns. These can take anywhere from several months to over a year to resolve, particularly when multiple years or complex business arrangements are involved.

How Long Can the IRS Audit Your Return?

The IRS generally has three years from the date a return was filed (or its due date, whichever is later) to assess additional tax. This is the standard statute of limitations for most audits.

However, the IRS has six years to audit if it believes you underreported gross income by more than 25%. And there is no statute of limitations at all in cases of fraud or when no return was filed. This is one of many reasons why filing accurately and on time matters — it starts the clock running on the IRS’s window to examine your return.

What Affects How Long a Tax Audit Takes?

Several factors influence the timeline of any given audit:

How quickly you respond to IRS requests — delays on your end extend the timeline
The completeness and organization of your records — well-documented returns resolve faster
The number of issues under review — audits covering multiple years or multiple issues take longer
Whether there are disagreements that require appeals — adding months or more to the process
Whether you have professional representation — a CPA or EA who handles the IRS communication and responds to requests efficiently can significantly shorten the timeline

What Happens If You Disagree With the Audit Findings?

If you disagree with the IRS’s proposed changes after the audit, you have the right to appeal. The appeals process can add additional months to the total timeline, but it is often worthwhile when the proposed adjustment is significant. A tax professional can evaluate whether an appeal is likely to succeed and manage the process on your behalf.

Why Professional Representation Matters

One of the most important things you can do when facing an IRS audit is to not go through it alone. A licensed CPA can communicate with the IRS directly on your behalf, identify what documentation is needed, respond to requests accurately and efficiently, and — critically — prevent you from saying things in an IRS interview that could inadvertently expand the scope of the examination.
