If you accidentally miss something on your tax return, you can correct it by filing an amended return using Form 1040-X, Amended U.S. Individual Income Tax Return. If it's a minor error, the IRS may automatically correct it or contact you, but significant omissions affecting income, deductions, or credits should be amended to avoid penalties and interest.
If you made a mistake when you filed your tax return, you can file an amended tax return to correct that mistake. Filing an amended tax return can also help you claim deductions and credits that you might have missed when filing your original return.
Use Form 1040-X, Amended U.S. Individual Income Tax Return, and follow the instructions. You should amend your return if you reported certain items incorrectly on the original return, such as filing status, dependents, total income, deductions or credits.
Here's how to request a change to your tax return:
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
Often, the IRS will recalculate your tax return by including the missing income and determining the amount of tax they think that you owe. This can include penalties and interest. If you realize that you didn't include some income on your tax return, you can file an amended return that includes the missing information.
An IRS notice may alert you to a mistake on your tax return or that it's being audited. You can verify the information that was processed by the IRS by viewing a transcript of the return to compare it to the return you may have signed or approved. You can access your tax records through your account.
Note: filing an amended return does not affect the selection process of the original return. However, amended returns also go through a screening process and the amended return may be selected for audit. Additionally, a refund is not necessarily a trigger for an audit.
File an amended return: You can file an amended return (Form 1040X) to correct any errors or omissions, or to include missing documents on your original return. Pay any additional tax due: If you owe back taxes, you'll need to pay the amount due, plus any interest and penalties.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
When your amended return has completed processing, the IRS will issue a new refund. Allow 8 to 12 weeks for your amended return to be processed; however, in some cases, processing can take up to 16 weeks.
There's no penalty just for filing an amended tax return (Form 1040-X), but if your mistake led to underpaid taxes, you'll owe the additional tax plus interest and potential penalties, like accuracy-related ones (20-40%) for negligence or substantial understatement, unless you pay quickly or show reasonable cause. Filing voluntarily before the IRS finds the error is best, as it helps you avoid penalties, and you should pay any owed tax by the original deadline to prevent interest and penalties, though the IRS calculates them if you file late, notes Business Insider.
If you realize there was a mistake on your return, you can amend it using Form 1040-X, Amended U.S. Individual Income Tax Return. For example, a change to your filing status, income, deductions, credits, or tax liability means you need to amend your return.

Attorneys, certified public accountants, enrolled agents or anyone who gets paid to prepare tax returns may owe a penalty if they don't follow tax laws, rules and regulations.
If there is a potential discrepancy, a tax examiner will look further into your reported income. They'll compare the information reported to the IRS by employers, banks, businesses, and of payers to the income, credits, and deductions on your report.
You may receive penalty relief where a penalty would otherwise be imposed if you have made an error in your income tax return or activity statement.
Many people worry about IRS audits. But the chances of being audited are actually very low for most individuals. Recent IRS data shows the IRS examined 0.40% of individual returns filed and 0.66% of corporation returns filed. Most of the IRS's focus is on large businesses and high-income earners.
