Filing your taxes correctly is important, but mistakes can still happen.
You may realize later that you forgot to report income, missed a deduction, entered incorrect information, or need to update your filing status.
When this happens, the IRS allows you to correct your original tax return by filing Form 1040-X, also known as the Amended U.S. Individual Income Tax Return.
While filing Form 1040-X is an important step, many taxpayers are unsure about what happens after the amendment is submitted. Questions about processing times, refunds, IRS reviews, and the next steps are very common.
Unlike regular tax returns, amended returns usually go through a more detailed review process, which means they can take longer to process.
If your amendment involves business income, older tax years, or multiple corrections, Virtue CPAs works closely with taxpayers to prepare clean, well-documented Form 1040-X filings that hold up to manual IRS review without unnecessary follow-up.
In this guide, you will learn what happens after filing Form 1040-X, how long processing usually takes, how to track your amended return status, possible delays, and the important steps you should take while waiting for the IRS to complete the review.
Key Takeaways
- Form 1040-X is the IRS form used to correct mistakes on a previously filed federal income tax return, including income, deductions, credits, filing status, or dependents.
- Amended returns go through manual IRS review, so processing typically takes 8 to 16 weeks and can stretch longer during busy seasons or IRS backlogs.
- Electronic filing is generally faster than paper filing, but even e-filed 1040-X returns take noticeably longer than original returns.
- You can track your amended return through the IRS "Where's My Amended Return?" tool, which shows three statuses: Received, Adjusted, and Completed.
- An amendment can result in an additional refund or additional taxes owed, depending on the corrections you make.
- Common causes of delay include missing information, math errors, missing schedules, and identity verification reviews.
- Avoid filing duplicate amendments while waiting, keep supporting documents organized, and respond promptly to any IRS notices.
What Is Form 1040-X?
If you discover an error after filing your tax return, Form 1040-X is the official IRS form used to correct that mistake.
It allows you to amend a previously filed federal income tax return and update the information accurately.
Purpose of IRS Form 1040-X
Form 1040-X is designed to help taxpayers correct information on a previously submitted tax return.
You may need to amend your return if you:
- Reported incorrect income
- Forgot to claim deductions or credits
- Used the wrong filing status
- Added or removed dependents
- Received corrected tax documents after filing
The form allows the IRS to review the changes and update your tax account accordingly.
Common Reasons for Filing an Amended Return
There are several common situations where taxpayers file Form 1040-X.
These may include:
- Missing W-2s or 1099 forms
- Forgetting education or child tax credits
- Correcting business or self-employment income
- Updating filing status
- Fixing errors related to dependents
- Correcting mathematical or reporting mistakes
For you, filing an amended return can help ensure your tax records are accurate and may even result in an additional refund in some cases.
When You Should File Form 1040-X
Not every mistake requires an amended return.
The IRS may automatically correct certain simple errors, such as minor math mistakes. However, you should generally file Form 1040-X if the correction affects:
- Your income
- Tax liability
- Refund amount
- Filing status
- Tax credits or deductions
It is also important to wait until your original tax return has been processed before filing an amendment.
For you, understanding when an amendment is necessary can help avoid unnecessary delays or duplicate filings.
What Happens Immediately After Filing Form 1040-X?
After you file Form 1040-X, the IRS begins a separate review process for your amended return.
Unlike regular tax returns that are often processed automatically through IRS systems, amended returns usually require additional manual review.
Understanding what happens during this stage can help you know what to expect and reduce unnecessary anxiety while waiting for updates.
IRS Receives and Reviews the Amended Return
Once your Form 1040-X is submitted, the IRS first confirms receipt of the amended return.
The return then enters the IRS review system, where agents examine:
- The corrections you made
- Supporting documents attached
- Differences between the original and amended return
- Any changes affecting taxes owed or refunds
For you, this means the IRS does not simply replace your original return. Instead, they compare both versions carefully before making adjustments to your tax account.
Electronic vs Paper Filing Differences
The way you file your amended return can affect processing speed.
Electronic filing is generally faster because the IRS receives and enters the information directly into its system. Paper-filed amendments usually take longer because they require manual handling and data entry.
However, even electronically filed amended returns may still take significantly longer than standard tax returns.
For you, filing electronically when eligible can sometimes help reduce delays.
Why Processing Takes Longer Than Regular Returns
Many taxpayers are surprised by how long amended returns can take.
This happens because Form 1040-X often requires manual review by IRS employees rather than automated processing systems. The IRS may also need to:
- Verify documents
- Confirm calculations
- Review credits or deductions
- Conduct identity checks
- Adjust multiple tax records
During busy tax seasons or periods of IRS backlog, processing may take even longer.
For you, patience is important because amended returns are usually handled more carefully and slowly than original tax filings.

How Long Does Form 1040-X Take to Process?
One of the most common questions taxpayers ask after filing an amended return is how long the IRS will take to process Form 1040-X.
Unfortunately, amended returns usually take much longer than regular tax returns, and processing times can vary depending on several factors.
Standard IRS Processing Timeline
In many cases, the IRS states that Form 1040-X processing may take around 8 to 16 weeks or longer.
However, some amended returns may take several months before they are fully completed.
Official IRS Amended return tracking information is available online.
For you, it is important to understand that delays are common and do not always mean there is a problem with your amendment.
Factors That Can Delay Processing
Several issues can slow down the review process for Form 1040-X.
Common delays may include:
- Missing or incomplete information
- Incorrect calculations
- Missing supporting documents
- Identity verification checks
- IRS staffing shortages or backlogs
- Large changes to income or deductions
If the IRS needs additional information, they may also send notices requesting clarification before processing can continue.
For you, filing an accurate and complete amended return can help reduce the chances of unnecessary delays.
When Processing May Take Several Months
Some amended returns require more detailed review than others.
Processing may take significantly longer if:
- Multiple tax years are involved
- Business income corrections are included
- Complex deductions or credits are changed
- Fraud or identity verification reviews are triggered
- Older returns are being amended
For you, complex tax situations often require extra patience because the IRS may need additional time to verify information carefully.
How to Track the Status of Your Form 1040-X
After filing an amended return, it is completely normal to want updates on its progress. Fortunately, the IRS provides an online tool that allows you to monitor the status of your Form 1040-X.
Understanding how the tracking system works can help you stay informed while your amended return is being processed.
Using the “Where’s My Amended Return?” Tool
The IRS offers an online tracking system called “Where’s My Amended Return?” that allows taxpayers to check the status of Form 1040-X.
The system generally updates once every 24 hours and allows you to monitor your amended return throughout the processing stages.
For you, this tool is often the easiest way to get updates without contacting the IRS directly.
Information Needed to Check Status
To track your amended return, you will typically need:
- Your Social Security Number
- Your date of birth
- Your ZIP code
The IRS uses this information to locate your amended return in its system.
For you, it is important to enter the information exactly as it appeared on your tax return to avoid tracking issues.
IRS Status Updates
The IRS tracking tool usually displays one of three main statuses:
- Received
- Adjusted
- Completed
Each status reflects a different stage of the review process.
These updates help you understand whether the IRS has received your return, made account changes, or completed processing.
For you, monitoring these status updates can provide reassurance while waiting for the final outcome of your amendment.
What Do IRS Status Updates Mean?
When you check the status of your amended return using the IRS tracking tool, you will usually see one of three status updates.
Return Received
The “Received” status means the IRS has successfully received your amended return and entered into its system.
At this stage:
- Your amendment is waiting for review
- The IRS has not yet completed processing
- No final decision has been made
For you, this status mainly confirms that the IRS has your Form 1040-X, and that processing has officially started.
It is common for the return to remain in this stage for several weeks while waiting for manual review.
Return Adjusted
The “Adjusted” status means the IRS has reviewed your amended return and made changes to your tax account.
This could include:
- Adjusting your refund amount
- Updating taxes owed
- Correcting tax records
- Applying approved changes from your amendment
- At this stage, the IRS may still be finalizing certain account updates before completing the process fully.
For you, this usually means your amendment is moving forward, and the IRS has accepted at least some of the corrections submitted.
Return Completed
The “Completed” status means the IRS has finished processing your amended return.
At this point:
- Any refund adjustments may be issued
- Additional tax balances may be finalized
- IRS account updates are complete
You may also receive an IRS notice explaining the final outcome of your amendment and any account changes made.
For you, this is the final stage of the Form 1040-X process.
Will You Receive an Additional Refund or Owe More Taxes?
One of the biggest reasons taxpayers file Form 1040-X is to correct tax amounts that may affect refunds or taxes owed.
Depending on the changes made in your amended return, the outcome could either increase your refund or create an additional tax balance.
Situations Resulting in a Refund
In some cases, filing an amended return may result in an additional refund from the IRS.
This can happen if you:
- Missed deductions on your original return
- Forgot to claim eligible tax credits
- Reported income incorrectly
- Corrected filing status errors
- Added eligible dependents
Once the IRS reviews and approves the changes, any additional refund amount may be issued through direct deposit or a mailed check, depending on your account setup.
This means filing Form 1040-X could potentially help recover money you were originally entitled to receive.
Situations Resulting in Additional Taxes Owed
Not all amended returns lead to refunds.
In some situations, correcting your tax return may show that you actually owe additional taxes to the IRS.
This commonly happens when:
- Income was underreported
- Taxable income was omitted
- Incorrect deductions or credits were claimed
- Business income adjustments increased tax liability
If you owe additional taxes, the IRS may send a notice explaining the updated balance due.
Paying any owed taxes promptly can help reduce additional interest or penalties.
Interest and Penalties
Depending on the situation, the IRS may apply interest or penalties to unpaid tax balances.
Interest generally continues accumulating until the balance is fully paid.
Penalties may apply if:
- Taxes were significantly underpaid
- Payment deadlines were missed
- Incorrect information caused tax underreporting
Filing an amended return voluntarily is usually better than waiting for the IRS to discover the issue later.

What Should You Do While Waiting for Processing?
Waiting for the IRS to process Form 1040-X can feel stressed, especially when processing takes several weeks or even months.
During this period, there are a few important things you should and should not do to help avoid additional delays or complications.
Avoid Filing Duplicate Amendments
One of the biggest mistakes taxpayers make is submitting another amended return because they think the first one was not received.
Filing duplicate amendments can create:
- Additional processing delays
- IRS confusion
- Duplicate account reviews
- Longer wait times
It is usually best to wait for updates through the IRS tracking system unless the IRS specifically requests additional information.
Keep Supporting Documents Ready
While your amendment is under review, it is important to keep copies of all related documents organized and accessible.
This may include:
- W-2s and 1099s
- Receipts and deduction records
- Tax schedules and worksheets
- IRS notices and correspondence
- Copies of your original and amended returns
If the IRS requests clarification or supporting evidence, having these documents ready can help you respond quickly.
Staying organized can reduce stress and help avoid further delays.
Continue Monitoring IRS Updates
The IRS tracking tool can help you monitor progress while your amendment is being processed.
Checking updates periodically allows you to:
- Confirm the IRS received your return
- Track status changes
- Identify whether additional action may be needed
However, checking constantly usually does not speed up processing.
Occasional monitoring is generally enough while waiting for the IRS to review.
Respond Promptly to IRS Notices
If the IRS sends a letter requesting more information, it is important to respond as quickly as possible.
Delays in responding may slow down processing even further.
IRS notices may request:
- Missing documentation
- Identity verification
- Clarification of tax changes
- Payment information
Timely communication with the IRS can help keep your amended return moving through the review process smoothly.
Common Reasons Form 1040-X Gets Delayed
Amended returns already take longer to process than regular tax returns, but certain mistakes or issues can slow the process down even more.
Learning about the most common causes of delays can help you avoid unnecessary problems when filing Form 1040-X.
Missing or Incorrect Information
One of the most common reasons for delays is incomplete or incorrect information on the amended return.
This may include:
- Missing signatures
- Incorrect Social Security numbers
- Incomplete sections of the form
- Incorrect filing status information
- Missing explanations for changes made
Reviewing the form carefully before submission can help reduce avoidable processing issues.
Mathematical Errors
Calculation of mistakes can also delay IRS review.
If the numbers on your amended return do not match supporting schedules or prior filings, the IRS may need additional time to verify the information manually.
Even small inconsistencies can slow down processing.
For you, double-checking calculations before filing can help improve accuracy and reduce delays.
Missing Supporting Schedules or Documents
Many amended returns require additional forms, schedules, or supporting documentation.
If required attachments are missing, the IRS may pause processing while requesting more information.
Examples may include:
- Updated W-2 or 1099 forms
- Revised tax schedules
- Deduction documentation
- Credit eligibility proof
Attaching all required supporting documents at the time of filing can help keep the process moving more smoothly.
Fraud or Identity Verification Reviews
In some cases, the IRS may conduct additional identity, or fraud verification checks before completing the amended return.
This can happen if:
- Large income changes are reported
- Refund amounts change significantly
- Identity theft concerns are detected
- Taxpayer information appears inconsistent
While these reviews can extend processing times, they are designed to protect taxpayer accounts and reduce fraud risks.
When Should You Contact a Tax Professional?
While some amended tax returns are straightforward, others can become complicated quickly.
If your Form 1040-X involves multiple corrections, large financial changes, or IRS notices, getting professional guidance may help you avoid costly mistakes and unnecessary stress.
Complex Tax Amendments
Some tax amendments involve more than simple corrections.
You may benefit from professional help if your amended return includes:
- Business or self-employment income
- Multiple years of corrections
- Investment or rental income changes
- Large deduction adjustments
- Complex tax credits
- Multiple supporting schedules
Professional review can help ensure the amended return is accurate before it reaches the IRS.
Large Refunds or Tax Balances
If your amendment could significantly increase your refund or result in a large balance due, professional guidance may be especially valuable.
Large financial adjustments may require careful review to avoid:
- Additional IRS scrutiny
- Incorrect calculations
- Missed documentation
- Penalties or interest issues
Understanding the financial impact of your amendment before filing can help prevent surprises later.
IRS Notices or Delays
If the IRS sends notices requesting clarification or if your amended return remains delayed for an unusually long time, working with a tax professional may help simplify communication and resolution.
A professional can help you:
- Understand IRS letters
- Prepare supporting documentation
- Respond accurately to IRS requests
- Navigate complex tax situations more confidently
This can reduce stress and improve communication during the amendment process.
