How Often Does the IRS Make Mistakes?

The Internal Revenue Service (IRS) is responsible for processing millions of tax returns each year. While the IRS strives for accuracy, mistakes can happen. Understanding the frequency and types of errors the IRS makes can help taxpayers identify and address any potential issues.

Frequency of IRS Mistakes

According to a 2017 study by the Treasury Inspector General for Tax Administration (TIGTA), the IRS makes errors in less than 1% of the returns it processes. This means that for every 10,000 tax returns filed, the IRS makes an error on just 100 of them.

While 1% may seem like a small number, it still translates to a significant number of errors given the vast volume of returns processed by the IRS. In 2022, the IRS processed over 155 million individual tax returns. Based on the TIGTA study, this means that over 1.5 million returns may have contained errors.

Types of IRS Mistakes

IRS mistakes can take various forms, including:

  • Mathematical errors: These are simple math errors, such as addition or subtraction mistakes, that can occur during data entry or calculations.

  • Auditor misinterpretation: Auditors may misinterpret tax laws or guidelines, leading to incorrect assessments.

  • Data entry errors: Errors can occur during the manual or electronic entry of data, such as transposed numbers or incorrect names.

  • Omission of income or deductions: The IRS may fail to include all sources of income or deductions
