What is an amended tax return, and when should I file one?
An amended tax return is a way to fix mistakes or make changes to a tax return you’ve already filed. You should file Form 1040-X if you realize you left something out, reported incorrect income, or need to update your filing status.
For example, you might have forgotten to include a tax credit or deduction that could lower the amount of taxes you owe.
To file an amended return, you’ll need to use IRS Form 1040-X, which is specifically designed for making corrections. This form lets you explain what you’re changing and include any extra documents that might be needed.
Can I file an amended return electronically, or does it need to be mailed?
In many cases, you can file an amended return electronically if you’re working with a tax professional that is e-File Authorized. This option is available if your original tax return was also filed electronically and it’s for one of the last three tax years. If your original return was mailed in, or if the tax year is older than three years, you’ll need to mail the amended return to the IRS.
If you’re e-filing, make sure the tax software you’re using supports amended returns. If mailing, double-check the address listed in the instructions for Form 1040-X to avoid delays.
What is the deadline for filing an amended tax return?
You generally have three years from the date you filed your original tax return to file an amendment. If you pay taxes later, you have two years from the date of payment—whichever gives you more time. For example, if you filed your taxes on April 15, 2022, you have until April 15, 2025, to file an amendment.
There are some exceptions to this rule, such as if you’re claiming certain tax benefits like a net operating loss. If you’re unsure about your specific situation, it’s a good idea to check with a tax professional or the IRS for guidance.

How do I track the status of my amended return?
You can find out what’s happening with your amended return using the “Where’s My Amended Return?” tool on the IRS website. It shows updates for the current tax year and the three years before that.
To use it, you’ll need your Social Security number, date of birth, and ZIP code.
Processing an amended return usually takes about 16 weeks, but it can take longer during busy times or if the IRS needs more information from you.
What is the process of filing an amended return?
- Gather your documents: Collect all necessary paperwork, such as W-2s, 1099 forms, and your original tax return. If you’re correcting deductions, have forms like Schedule A for itemized deductions or records of capital gains and losses ready.
- Fill out Form 1040-X: This form is used to explain the changes to your tax return. For example, you might need to update your tax liability, add income, or include missed deductions. Attach any new or corrected documents.
- Check state tax requirements: If your federal return changes affect your state taxes, you may also need to file an amended state return. Each state has its own rules, so check with your state’s tax office.
- Submit your amended return: Depending on your circumstances, you can e-file or mail the 1040-X to the IRS. If mailing, make sure it goes to the correct address listed in the instructions.
- Pay any taxes owed: If your amendment shows you owe more taxes, pay the amount as soon as possible to avoid penalties and interest. You can use IRS payment methods like direct pay or electronic funds transfer.
- Seek professional help if needed: If your tax situation is complex or involves multiple years, a tax professional can ensure you file correctly.
Can I amend my return more than once?
Yes, you can make changes to a tax return more than once if needed. However, it’s better to try to get everything right in one amendment to avoid confusion.
Each time you amend a return, you need to complete a new Form 1040-X and include any necessary documents. This can slow down the process and increase the chance of mistakes.
Before you amend your return, carefully review both your original filing and the changes you plan to make. If you’re not sure about something, consider asking a tax professional for help.
Can I amend my return to claim missed credits or deductions?
Absolutely. If you forgot to claim tax credits or deductions, you can file an amended return to get them. Some common ones people miss include:
- Earned Income Tax Credit (EITC): A credit for people with lower to moderate incomes.
- Child Tax Credit (CTC): A credit for parents or guardians of qualifying children.
- Education-related credits: Such as the American Opportunity Credit or Lifetime Learning Credit for college expenses.
Amending your return to claim these can reduce your tax bill or increase your refund. Just make sure to include any proof or documents the IRS might need.
How does amending a joint return affect both spouses?
If you’re fixing a tax return you filed jointly with your spouse, the changes apply to both of you. Both spouses need to sign the amended return to show they agree with the corrections.
If one spouse doesn’t agree with the changes, things can get tricky. In that case, it’s a good idea to get help from a tax professional to figure out the best steps to take and make sure you’re following IRS rules.
What happens if the IRS denies my amended return?
If the IRS denies your amended return, it’s often because of missing information, incomplete documents, or filing after the deadline. You’ll get a notice explaining the reason for the rejection.
To resolve this, provide the missing information or documents requested. If you believe the denial is a mistake, you can appeal the decision by following the instructions in the notice or contacting the IRS.
Can I amend my state tax return at the same time as my federal return?
Yes, you can.
If your federal amendment affects your state taxes, you’ll likely need to amend your state return too. Each state has its own process, so check with your state’s tax agency for the right form and instructions.
It’s a good idea to amend both returns around the same time to ensure everything matches and avoid discrepancies.
Can amending my return trigger an IRS audit?
Filing an amended return doesn’t automatically trigger an audit, but the IRS will review the changes. If your amendment significantly changes your income, deductions, or credits, it might get extra attention.
To reduce the risk of an audit, make sure your amended return is accurate, complete, and supported by proper documents. If you’re unsure, a tax professional can help.
How do I handle amending returns for multiple years at once?
If you need to amend returns for multiple years, you must file a separate Form 1040-X for each year. Clearly label each form with the tax year it applies to, and attach the necessary documents for that year.
When mailing multiple amended returns, send each one in a separate envelope to avoid confusion.
