Does The IRS Make Mistakes?

Yes – the IRS processes approximately 155 million individual tax returns each year, and errors occur at multiple levels. The scale of these mistakes is notable: the IRS itself identified and sent out 1.6 million notices related to mathematical errors in recent years. While the IRS works to catch mistakes, they can come from many sources, including the IRS itself, employers submitting incorrect W-2s, HR departments making reporting mistakes, or tax preparers entering incorrect information.

If you believe there’s an error on your tax return or IRS notice, our tax consulting services can help you identify and address these issues correctly.

How Often Do IRS Mistakes Really Happen?

IRS mistakes are actually quite rare. In fact, a 2017 study by the Treasury Inspector General for Tax Administration found that the IRS makes errors in less than 1% of the returns it processes. That means that for every 10,000 tax returns filed, the IRS makes an error on just 100 of them.

Of course, even a 1% error rate is still too high for some people. After all, we’re talking about billions of dollars in taxes here. So what happens when the IRS does make a mistake? Well, first of all, it’s important to note that taxpayers are not responsible for paying any interest or penalties on erroneous tax bills. And if you believe that you’ve been incorrectly assessed a tax bill, you can file an appeal with the IRS. The appeals process is designed to give taxpayers a fair hearing and ensure that they are only required to pay taxes that they actually owe.

7 Most Common IRS Errors

  1. Mathematical errors or typos in calculations or data entry
  2. Auditor misinterpretation of tax laws and guidelines
  3. Data entry errors caused by machine scanning, OCR (optical character recognition) software, or human input
  4. Failure to include all sources of income or deductions claimed on tax returns
  5. Failure to apply certain tax credits or deductions that taxpayers are eligible for
  6. Mismatched or incorrectly entered names, Social Security Numbers, or other personal identifiers can delay the processing of returns or credits
  7. Incorrect application of tax laws to items such as foreign accounts, cryptocurrency, or self-employment income.

How Do You Prove That The IRS Made A Mistake?

Gather your paperwork together. If you find an IRS mistake, write a letter that clearly explains the error and then attach documentation showing that what you filed was accurate.

If your employer accidentally sent two versions of a W-2, the IRS might double your income and assess a significant tax bill. By writing to explain the error and attaching documentation, you can often resolve the issue. You should receive a response in several weeks. If you do not, it is crucial to follow up or the situation could get worse.

Where Do You File An Appeal?

When a letter and explanation does not solve the issue, the next step is often to file a written protest with the IRS Office of Appeals. This independent organization provides an objective point of view in resolving tax disputes. Programs such as Fast Track Settlement and mediation often can resolve issues at the early stages of an audit or collection efforts.

What Do You Need To Include On A Formal Protest?

Before filing a formal protest, it is often helpful to seek legal advice to ensure you make the strongest possible argument with the first appeal. Some of the things that must be included in a protest are:

  • The Basics: Your name, address, phone, a statement asking to appeal IRS findings to the Office of Appeals, copy of the IRS letter with proposed changes and tax years involved.
  • A List of Issues: Address each argument individually along with the reason you disagreed and any facts or law that support your position. Add any documentation that supports your position.
  • Perjury Statement: Include a statement that states: “Under the penalties of perjury, I declare that the facts stated in this protest and any accompanying documents are true, correct, and complete to the best of my knowledge and belief.” Sign under this statement.

With any administrative hearing process, it is important to lead with your strongest arguments. And when you worry that the IRS did not correctly apply the law to your situation, individualized legal counsel may be the difference between winning early or long and drawn out litigation.
