Filing an original tax return is a significant task, but sometimes errors slip through or new information emerges after submission. When that happens, taxpayers can file an amended return using Form 1040-X to correct or update their information. However, the IRS does not simply update your return automatically. Instead, it initiates a detailed review process to verify all changes, ensuring they are accurate and comply with tax regulations.
Why File an Amended Return?
Taxpayers may need to amend their returns for several reasons, such as reporting additional income like freelance earnings, correcting filing status, or claiming missed deductions and credits. Since these changes affect your tax liability, the IRS treats amended returns with more scrutiny than original filings.
Step-by-Step IRS Review of Amended Returns
-
Initial Processing and Logging
Once your Form 1040-X is received, the IRS manually logs and assigns it to a specialized team. Unlike electronically filed returns, amended returns are processed by mail, leading to longer processing times—typically 8 to 12 weeks, sometimes more. -
Verification of Reported Changes
The IRS compares the amended return against your original to verify the math and validate any changes in income, deductions, or credits. This step ensures that all adjustments are substantiated and compliant. -
Request for Additional Documentation
If necessary, the IRS may request supporting documents such as W-2s, 1099 forms, receipts, or other records. Responding promptly to these requests is essential to avoid delays. -
Communication and Resolution
The IRS communicates the outcome of the review via mail. You will receive either an acceptance notice confirming your amended return or a letter detailing proposed adjustments or explanations if the IRS disagrees with your changes. -
Final Account Update
Upon completion, the IRS updates your tax account to reflect any additional tax owed, refunds due, or no change. It’s important to keep copies of all correspondence for your records.
Example Scenario
Consider a taxpayer who forgot to report $2,000 of freelance income on their 2023 tax return. After filing Form 1040-X, the IRS reviews the amendment, requests a copy of the 1099-NEC form, and ensures the additional income is correctly taxed. They then adjust the tax balance, which may result in additional tax owed.
Who Should Expect This Process?
Anyone filing Form 1040-X to correct or add information after the original return will undergo this process. It commonly affects individual taxpayers, small business owners, freelancers, and investors looking to rectify income or claim new deductions.
Tips for a Smooth Amended Return Review

Common Misconceptions

- Ignoring IRS Requests: Failing to respond to IRS inquiries can delay or derail your amendment
