What Form 1040X Is For
IRS Form 1040X (2011) is the IRS form taxpayers use to correct an original return after it’s been filed. You can use it to fix errors or update information such as income, deductions, or credits. It lets you change your filing status—from single to married filing jointly—or claim dependents you initially missed. The form includes three columns: your original numbers, the changes, and the corrected totals, so the IRS can easily compare entries. In short, Form 1040X is your tool for officially amending your return and ensuring that your tax record reflects accurate information.
When You’d Use Form 1040X
You should file Form 1040X after submitting your original return if you discover a mistake or a change that affects your refund or the additional tax you owe. Below are the most common situations and requirements:
- Filing Trigger: After working with a tax preparer or reviewing your return, you realized an error.
- Corrections: You need to update figures on your schedules, report new income, or claim missed deductions or credits.
- Timing: You must submit the amended version within three years of the original filing date or two years from when you paid the tax—whichever is later.
- State Updates: If your changes affect your state tax return, you must file an amendment.
- Payment: If you owe more tax, pay the amount promptly to avoid interest and penalties.
Prepare and complete your Form 1040X carefully before mailing it to the IRS. Check out our individual tax forms page to see the most common IRS forms used by individual filers. You can review each form and decide which ones you may need for your return.

Common Mistakes and How to Avoid Them
Filing an amended return is straightforward when done carefully, but minor oversights can delay your refund or prompt IRS inquiries. Here are the most frequent mistakes—and how to avoid them:
- Filing too soon: Submitting Form 1040X before your original return is fully processed can be confusing. Wait until you receive your refund or confirmation notice before filing the amendment.
- Missing explanations: Many taxpayers skip Part III. Provide an apparent reason for each correction to help expedite the IRS verification process.
- Forgetting attachments: Missing W-2s or schedules can stall your correction. Double-check that all supporting forms are securely attached.
- Using the wrong address: Submitting the form to an incorrect IRS center may result in delays. Use the address listed in the latest instructions for the 2011 amendments.
- Not keeping copies: Keep a complete copy of your amended return and attachments for your records in case the IRS sends follow-up questions.

What Happens After You File
After submitting the Amended U.S. Individual Income Tax Return (2011), the IRS reviews your information to confirm the changes. Your form is received, entered into their system during the first few weeks, and prepared for processing. Most amended returns are reviewed within eight to twelve weeks, although more complex cases may require additional time.
When the review is complete, the IRS will send a notice explaining the result—whether you’re due a refund, no change is needed, or you owe additional tax. If you owe money, pay promptly to avoid interest or penalties. Because the 2011 amendments couldn’t be tracked online, taxpayers had to call the IRS for updates. Remember to update your state tax return if your correction affects federal figures.
