What Is an Amended Tax Return?
An amended tax return is a do-over of your original tax filing. When you file a tax return amendment, you’re telling the IRS you must fix something on your previous return. Maybe you forgot to include some income. You may have learned you can get the Earned Income Tax Credit (EITC) or found extra deductions to claim.
Think of this process as editing your tax return. Instead of starting from scratch, you’re updating the information with new details. The IRS uses Form 1040-X for amended tax returns, showing your original and corrected numbers.
The amended tax return form lets you make essential corrections that can affect your tax situation. Whether you’re adjusting income, deductions, credits, or your filing status, this form can help you set things right with the IRS. You can avoid surprises later on while getting the most money back and staying compliant with tax laws.
When Should You File an Amended Tax Return?
Can you amend my tax return if you already filed it? The answer is yes, and there are several good reasons to do so. Here are some common situations where filing an amended return makes sense:
- You received a corrected W-2 from a previous employer after filing
- You forgot to claim certain deductions
- You need to change your filing status (like from single to married filing jointly)
- You made math errors on your original return
- You realized you qualify for additional credits you didn’t claim
- You received new tax documents after filing
- You forgot to report some income
- You need to add or remove dependents
- You discovered additional charitable contributions
- You realized you qualify for education credits you didn’t claim
Note: You don’t need to file an amended return for simple math errors. The IRS usually catches and corrects those automatically. They also don’t require amendments for forgotten attachments if they’ve already processed your return.
What Is the Filing Deadline for Amended Tax Returns?
Generally, you have three years from the date you filed your original return to amend it. If you paid taxes after the filing deadline, you have two years from the payment date to file an amended return.
For example, if you filed your 2023 taxes on April 15, 2024, you would have until April 15, 2027 to submit an amended return. This gives you ample time to discover and correct mistakes or oversights.
Keep in mind that if you’re seeking a refund, you’ll want to file your amended return as soon as possible.
How to File an Amended Tax Return
Now that you understand what an amended return is and when to file one, let’s walk through the process step by step.
Filing an amended tax return involves the following:
- Gathering specific documents
- Filling out the proper forms
- Submitting everything correctly to the IRS
While it might seem like a lot of work, breaking it down into manageable steps makes the process much easier.
1. Gather your tax documents
Collect all your important paperwork. Having everything organized will make the process smoother. You’ll need:
- Your original tax return (a complete copy)
- New or corrected tax forms (like W-2s or 1099s)
- Supporting documents for the changes you’re making
- Any notices from the IRS about your original return
- Social Security number
- Birth dates for everyone listed on your return
- Records of any payments made with your original return
2. Fill out Form 1040-X
You’ll make corrections using the amended tax return form (Form 1040-X). This form has three columns:
- Column A: Provide the amounts from your original tax return
- Column B: Show the net increase or decrease for the items you’re changing
- Column C: Enter the correct amounts
Take your time with this step. You’ll need to:
- Enter the original amounts you reported
- Input the correct amounts
- Explain why you’re making each change (be specific and clear)
- Attach any new or corrected forms that support your changes
- Double-check your math to avoid further amendments
- Review all changes carefully before submitting
Remember to complete all relevant parts of the form, even if you’re only changing one item. The IRS needs to see the complete picture of your tax situation.
3. Submit your amended return
You can e-file or mail Form 1040-X, depending on when and how you filed the original tax return. You can file Form 1040-X online if you’re amending a return from the current tax year or the past two years. However, if you filed your original return on paper, you must also submit your amendment on paper.
If you choose to file your amended tax return online, the IRS suggests you:
- Use tax filing software that supports Form 1040-X
- Make sure you have digital copies of all supporting documents
- Follow your software’s instructions carefully
If you’re filing by mail:
- Sign and date the form
- Attach all required supporting documents
- Mail it to the correct IRS address (check the Form 1040-X instructions for the right address)
- Keep copies of everything for your records
- Consider sending it by certified mail for tracking purposes
- Include any additional payment if you owe more taxes
Whether filing online or by mail, make sure everything is complete before submitting. Missing information or documents can delay processing.
How Long Does It Take to Process an Amended Return?
Once you submit your amended return, be prepared to wait. The IRS typically takes 8 to 12 weeks to process these returns, though it can sometimes take up to 16 weeks. During busy times or unusual circumstances, it might take even longer.
You can check the status of your form about three weeks after filing using the “Where’s My Amended Return?” tool on the IRS website. To use this tool, you’ll need:
- Your Social Security number
- Your date of birth
- Your ZIP code
