As the tax deadline approaches, many individuals and businesses find themselves scrambling to file on time. While filing under pressure can be stressful, rushing through your return often leads to costly mistakes. Whether you’re filing at the last minute or trying to catch up, it’s important to slow down just enough to avoid common errors that could trigger delays, audits, or penalties.
Here are some of the most frequent tax filing mistakes—and how to avoid them.
1. Incorrect or Missing Personal Information
One of the simplest yet most common mistakes is entering incorrect Social Security numbers, misspelling names, or forgetting to include a spouse or dependent’s information. Double-check all personal details before submitting your return. Even small typos can cause major issues.
2. Choosing the Wrong Filing Status
Your filing status affects your tax bracket, deductions, and credits. Selecting the wrong status—such as “Single” instead of “Head of Household”—can result in overpaying or underpaying taxes. If you’re unsure which status applies to you, a CPA can help determine the most beneficial option.
3. Math Errors
Manual calculations or incorrect input in tax software can lead to math errors. These mistakes are often flagged by the IRS, resulting in delayed refunds or notices. If you’re filing on your own, use reliable tax software with built-in error checks, or have a CPA review your return before submitting.
4. Forgetting to Report All Income
It’s essential to report all sources of income, including wages, freelance work, investment earnings, and side gigs. The IRS receives copies of your W-2s, 1099s, and other income documents—so if you leave something out, it won’t go unnoticed.
5. Overlooking Deductions and Credits
When you’re rushing, it’s easy to miss valuable deductions and credits, such as the Earned Income Tax Credit (EITC), Child Tax Credit, or deductions for student loan interest and charitable contributions. Take time to review what you’re eligible for, or work with a tax professional to ensure nothing is left on the table.
6. Missing Signatures
A missing signature is an automatic rejection for paper-filed returns. If you’re filing jointly, both spouses must sign. If you’re e-filing, make sure to follow all authentication steps to finalize your submission.
7. Using the Wrong Bank Information for Direct Deposit
Mistyping your routing or account number can delay your refund or even send it to the wrong account. Double-check this information before submitting your return. If you’ve changed bank accounts recently, make sure your current details are on file.
8. Failing to File State Taxes
While rushing to meet federal deadlines, many filers forget about their state obligations. Each state has its own filing requirements, deadlines, and forms. Make sure you understand and meet both state and federal filing responsibilities.
9. Not Filing at All
Some taxpayers mistakenly believe they don’t need to file if they can’t pay. This is one of the biggest mistakes you can make. Filing late is always better than not filing at all, and the IRS offers payment plans to help with owed balances.
10. Ignoring IRS Notices
If you make a mistake and receive a notice from the IRS, don’t ignore it. Responding promptly can help you avoid additional penalties and complications. A CPA can assist in interpreting notices and communicating with the IRS on your behalf.
