The Internal Revenue Service has released updated guidance to help taxpayers prevent IRS filing errors that can delay tax refunds or lead to penalties. The agency’s new tips, published on IRS.gov, emphasize filing electronically, double-checking information, and using IRS Free File to avoid errors and speed refund processing.
The IRS said that many taxpayers make simple mistakes when filing taxes each year. These common mistakes include entering the wrong Social Security numbers, choosing an incorrect filing status, or forgetting to sign their return. Such errors can delay refunds and may even result in a notice or additional interest charges being applied.
“Tax laws are complicated, but the most common tax return errors are surprisingly simple,” the IRS said in its guidance. “Many mistakes can be avoided by filing electronically. Tax software does the math, flags common errors, and prompts taxpayers for missing information.”
The agency recommends that taxpayers use IRS Free File or other trusted tax software to prepare their returns. These programs help calculate adjusted gross income, apply eligible tax credits and tax deductions, and verify the correct filing status before submission.
The IRS reports that selecting the wrong filing status remains one of the most common mistakes during tax preparation. Choosing an incorrect option can change the amount of the standard deduction and determine whether a taxpayer qualifies for certain tax credits, such as the dependent care credit. The agency advises using the Interactive Tax Assistant on IRS.gov to confirm eligibility.
Math errors also cause frequent delays. Adding or subtracting income and deductions incorrectly can lead to refund adjustments or penalties. Filing electronically through e-filing or trusted tax software helps ensure all calculations are accurate and all necessary forms are included before submission.
For those expecting a tax refund via direct deposit, the IRS advises taxpayers to carefully review their routing and account numbers before filing their tax return. Incorrect bank account information can misdirect refunds or cause delays in payments. The agency recommends double-checking all entries and looking for the locked padlock icon when entering sensitive data online.
The IRS also reminds taxpayers not to file taxes too early. Filing before receiving all necessary forms, such as W-2s, 1099s, or student loan interest statements, increases the risk of missing income or deduction details. Waiting ensures that the return is complete and accurate, preventing refund delays and the need for amended returns.
Filing electronically remains the fastest and most secure method for submitting a tax return. The IRS Free File program provides no-cost access to reliable tax software that verifies for missing information, mathematical errors, and incorrect entries before processing.
“Submitting your tax return electronically ensures greater accuracy than mailing your return,” the IRS said. “The e-file system detects common errors and rejects your return, sending it back to you for correction.”
The IRS notes that many taxpayers who file electronically receive their refunds faster through direct deposit, provided their bank account and routing information are correct. Electronic filing also reduces postage costs, prevents lost envelopes, and helps taxpayers claim all eligible deductions and credits.
Taxpayers who owe federal tax should still pay by the April 15 deadline, even if they request an extension. The IRS encourages filers to review all forms, sign and date the return, and verify the accuracy of dependent and income details before submission. Careful tax preparation helps avoid penalties, interest, and refund delays—ensuring that money reaches the correct account quickly and securely.
