Consequences of Filing Tax Returns with Errors: A Comprehensive Guide

Understanding the Impact of Tax Return Errors

When you file your income tax returns, it's important to ensure that all information is accurate and complete. Any errors can have significant consequences, ranging from monetary penalties to lengthy delays in tax processing. This guide will explore the various outcomes that may occur if you make mistakes on your tax returns and provide actionable steps to correct these errors promptly.

While accidental mistakes are not considered tax fraud, they are subject to penalties and interest charges. If the IRS or your state tax agency notices an error, it will send you a notice stating the amount that it believes you owe. It is your responsibility to demonstrate that your original return was correct or to pay the amount you owe, which might not be the same as the amount mentioned in the letter.

Steps to Take When You Discover Tax Return Errors

1. File an Amended Return

If you realize that you made a mistake on your tax return, your first action should be to file an Amended U.S. Individual Income Tax Return, also known as Form 104. This document is commonly referred to as the “Ooops I screwed up!” return. Filing this form promptly is crucial because it freezes the original return and removes it from the processing queue. A human IRS agent will then be assigned to examine both versions, which may result in a long delay while every line on both returns is manually examined.

2. Consider Both Underpayment and Overpayment Scenarios

Mistakes can go both ways. While you might only think that you may owe more money, many taxpayers unknowingly leave money due to them on the table because they don’t understand what they are eligible for. This underpayment or overpayment can amount to hundreds to thousands of dollars in unclaimed or overpaid amounts. Therefore, be prepared to file an amendment that corrects any overpayment or underpayment to ensure the most accurate tax return.

Penalties and Interest

Failure to correct a mistake in a timely manner can result in substantial penalties and interest charges. The IRS does not consider accidental mistakes as tax fraud; however, they do have strict guidelines for timely corrections. If you fail to file an amended return in time, you may be charged penalties and interest on any tax underpayment. These charges can significantly increase the amount you owe, making it even more important to address errors promptly.

Personal Experience

I can personally share a story about a former experience with tax return errors. Several years ago, I received a letter from the IRS with a notice of penalty and an order to pay the amount the IRS believed I owed, along with months of interest on this amount. I paid everything and was never contacted again, but this experience was enough for me to stop using TurboTax as a filer. The stress and financial impact were significant, and the process left a lasting impression on me.

Avoiding Future Errors and Ensuring Compliance

For Americans, keeping your financial life within the United States aligns with US tax code and reduces the risk of a financial penalty for making a mistake. If you are an American living abroad, quirks in the tax system can create challenges. The US tax code and associated laws are clear that Americans must stay on the tax plain. If you failed to file or file correctly, the consequences can be severe, as exemplified by the $246,000.05 penalty I once encountered.

By understanding the potential consequences of tax return errors and taking proactive steps to correct them, you can help protect your financial security and avoid unnecessary stress.
