How Long Does an IRS Tax Audit Take?

How Long Does an IRS Tax Audit Take?

The Internal Revenue Service (IRS) routinely performs tax audits of individual and corporate taxpayers. Though conducted yearlong, audits tend to spike during the months following tax season, when problematic tax returns come under the Service’s microscope. Regardless of when an audit or “examination” commences, an IRS auditor will be assigned to the case. Throughout the audit process, this designated auditor will handle correspondence with the taxpayer (or, if the taxpayer has appointed a personal representative, his or her tax audit attorney). While auditors are trained in efficiency, they are also trained to be thorough – and depending on the complexity and structure of the company or individual’s specific tax situation, the audit process often takes more time to complete than the average taxpayer might estimate.  This can be very disconcerting to taxpayer’s that are facing an egg shell audit scenario where the goal is to get the audit closed as soon as possible to mitigate any criminal tax exposure that underlies an audit.

How Long Does it Take the IRS to Complete a Tax Audit?

Before our IRS tax attorneys begin, it’s important to draw a distinction between the timeline for an audit and the statute of limitations for an audit. The latter can impact the former, but they are separate issues. The timeline for an audit is how long the auditing process itself will take. By comparison, the statute of limitations determines how far back into the taxpayer’s records the auditor may probe. Depending on the situation, the statute of limitations may allow the auditor to review tax returns and related records from up to three years ago, from up to six years ago, or from any point in the taxpayer’s history – even a tax return that is 15 or 20 years old. For more information about this subject, our IRS tax audit lawyers would encourage readers to explore the following articles:

While the statute of limitations on a tax audit generally ranges from three to six years (in cases where a limit exists), that does not mean a tax audit will require three to six years for the auditor to complete. As we will discuss momentarily, most audits conclude far sooner. However, as noted above, the statute of limitations can impact the timeline of an audit by creating boundaries for the examination of aging records.

Assuming the three-year statute of limitations applies – which, to reiterate, would not be the case if the audit involved egregious issues, such as a substantial understatement of the taxpayer’s income or evidence of tax fraud– the IRS has 36 months from the date of filing to examine the relevant tax return. However, eight of those months must be allotted for the processing of any appeals, meaning protests that are filed by the taxpayer. (Not everyone who is audited chooses to protest an IRS audit decision, or litigate if the matter is not solved in appeals, but taxpayers generally have the right to these options should questionable audit return findings arise because of differences in opinion on the facts or law underlying the audit.) With these eight months accounted for, the IRS has 28 remaining months – two years and four months – in which to perform the audit. Again, these limits would be extended if the IRS suspected serious violations or criminal activity, or if the taxpayer voluntarily allowed the IRS to extend the statute of limitations which should not be agreed to without the advice of qualified counsel.

The aforementioned does not mean the audit itself will take 28 months to complete – but it does create a framework the auditor must stay within. Most audits conclude within several months to about one year, but the precise duration of an audit depends heavily on three interrelated factors: (1) what type of audit is being conducted, and (2) the number and severity of the issues detected and the changes proposed (3) the efficiency and competence of the auditor and their manager. Needless to say, an audit which reveals a complex web of tax evasion will require more time for completion (and will invariably be accompanied by taxpayer fear and anxiety of subsequent or simultaneous IRS criminal investigation) than an audit which reveals a basic accounting errors, or which turns on missing receipts & documents.

While correspondence audits typically involve less serious taxpayer errors and thus ordinarily present the lowest potential for serious civil and criminal tax penalties, they can take months to complete while the taxpayer and IRS exchange documents and requests to produce documents, depending upon how rapidly the taxpayer responds. Unfortunately, the correspondence audit process can be needlessly dragged out by the IRS’ use of automation and call centers, which can create confusion if multiple representatives end up assisting the same taxpayer.  Unfortunately, the IRS eventually will close an unagreed correspondence audit via a 90-day letter which will force the taxpayer into either taking on the expense of litigation or allowing the assessment to take place uncontested.  A good tax litigation attorney can help you weigh the pros and cons of this decision.

By comparison, an office audit is considered to be a more intensive taxpayer examination – yet may wrap up in as little as a single day, unless the auditor asks the taxpayer to produce additional documentation, in which case more time will be allotted. Field audits, which are only conducted in cases where substantial errors or willful noncompliance have been detected, typically take longer than correspondence or office audits: approximately one year, give or take several months and often involves an interview of the taxpayer and a tour of the business under audit. The duration of any audit, regardless of type, can be extended by the following issues:

  • Failure to respond to an IRS audit notice
  • Filing a formal written protest (i.e. appealing the audit’s outcome), a process which should not be undertaken without IRS appeals representation. Our tax firm has extensive experience handling all types of IRS appeals, including correspondence audits and the accompanying CP2000 notices (Notices of Underreported Income) and large balances the IRS is attempting to legally assess based on an incorrect position on the underlying law or facts of the case following an office or field audit.
  • The individual auditor’s workload and whether he or she has any family/medical emergencies, which may necessitate reassignment.
