8 Common Mistakes to Avoid When Filing Your Taxes

Tax season can be complicated, and even meticulous filers can make errors. Many opt for professional help to ensure accuracy, but mistakes still happen. Here are eight frequent errors to be cautious of:

Waiting until the last minute to file can cause processing delays and slow refunds. Around one-third of taxpayers delay until the deadline, increasing the risk of errors and penalties.

Rushing to meet deadlines may cause mistakes, leading to processing issues and refund delays.

Submitting paper returns: Paper filings are more prone to errors than e-filing. Handwritten data and manual calculations often result in inaccuracies, so electronic submission is recommended for speed and correctness.

Input errors in electronic filing: Typographical mistakes in figures are common even when filing online. Precision is key to avoid delays caused by miscalculations.

Mistakes in entering personal data like names or Social Security Numbers can also cause rejection or delays. Accuracy here is vital.

forgetting to sign the return: An unsigned tax form is invalid and will be rejected. This simple oversight is common but easily overlooked.

Overlooking extension requests: Missing the filing deadline can result in penalties. However, requesting an extension on time can help avoid late fees—many taxpayers are unaware of this option.

Unnecessary professional fees: Some groups, such as seniors, students, or those with disabilities, qualify for fee waivers. Many miss out on these benefits, resulting in avoidable costs.

Not reporting overseas income: U.S. residents working abroad must file and pay taxes. Ignorance of this obligation can lead to severe penalties.
