Mistakes happen — even on tax returns. That's why the IRS allows taxpayers to correct their tax returns if they discover an error on a return that's already been filed. Here's what you need to know about filing an amended tax return.
There are times when you should amend your return and times when you shouldn't. Here are some common situations that call for an amendment:
Before filing an amended return, make sure the IRS has already processed the tax return you need to amend. That way, it will be less likely that the IRS will get your original return and amended return mixed up. If you've already received your tax refund, then you know the IRS has already processed your return.
You usually don't need to file an amended return if you discover math or clerical errors on a recently filed tax return. The IRS will often correct those types of mistakes on its own and, if necessary, send you a bill for the additional tax due or a refund if the error was in your favor.
The IRS could audit your previous years’ taxes, which may result in an additional tax liability. While the IRS typically audits returns filed within the last three years, it’s better to get ahead of any potential issues. Mistakes happen and they can be easily fixed by amending your return.
Filing an amended tax return as soon as you can is highly encouraged. That way, you can get ahead of any potential tax liabilities you may owe and minimize penalties .
The IRS limits the amount of time you have to file an amended return to claim a refund to:
If you're outside of that window, you typically can't claim a refund by amending your return.
The process for filing an amended return is fairly straightforward. Here's a step-by-step guide.
Gather your original tax return and any new documents needed to prepare your amended return.
If you need to correct the income you reported on your return, you may have a new or amended W-2 or 1099 form. If you missed claiming a tax deduction or credit, you’ll need documentation to support the new deduction you're claiming, such as a receipt for a charitable donation, new or amended Form 1098 Mortgage Interest Statement, or Form 1098-T to claim an education credit.
If you initially filed your tax return using TurboTax, you can access your tax return online or print a copy of that return by logging in to your account at TurboTax online or print a PDF of your return from the copy saved on your computer.
If you didn’t file using TurboTax and can’t locate a copy of your return, you can order a copy of your tax transcript using the Get Transcript tool on the IRS.gov website. Your transcript shows most of the lines from your tax return, including income, deductions, credits, and tax payments.
TurboTax Tip: When you file an amended return, you should include any new documents needed to support your changes, such as a new or amended W-2 or 1099 form to report additional income, a new or amended Form 1098 Mortgage Interest Statement, or a Form 1098-T to claim an education credit.
The IRS form for amending a return is Form 1040-X. You'll also need any forms that will be impacted by your change. For example, if you’re changing your itemized deductions, you’ll also need a copy of Schedule A for that tax year. To amend your tax return to add additional interest or dividend income, you'll likely need a copy of Schedule B. Changes to revenues or expenses from a trade or business will typically require Schedule C and Schedule SE. Updating your capital gains and losses might require Form 8949 and Schedule D, and so on.
You can also prepare your amended return in TurboTax. To do this, you need to use the version of TurboTax that applies to the tax year you need to amend. For example, if you need to amend your 2023 tax return, you need to use the 2023 version of TurboTax.
If you prepared your original tax return using TurboTax, log in to your account, open the tax return you already filed, and click on the link to amend your return. From there, the software will walk you through the process of filing the amendment.
If you didn't use TurboTax to file your tax return, you can use TurboTax to prepare the amendment. However, you'll first have to enter your information into TurboTax to match what you filed the first time, then start the process of amending it.
Form 1040-X contains three columns:
In Part III of Form 1040-X, you'll need to provide a clear explanation for your reasons for filing an amended return.
When you use TurboTax to prepare your amended return, you don’t need to know all the details. Once you indicate that you’re preparing an amended return, the software will help you fill out Form 1040-X and any supporting forms as you make changes to your income and deductions.
Beginning with the 2019 tax year, the IRS allows you to e-file amended tax returns if you filed the original return electronically and provided that your tax software supplier supports electronically filing amended returns. To amend a return for 2018 or earlier, you'll need to print the completed Form 1040-X and any other forms you're amending. Attach any necessary supporting documentation, such as:
Mail all the forms and documents to the address provided in the instructions or electronically file the return if you are able to.
If amending your tax return increases the refund amount you should get, the IRS will issue you an additional refund. This refund will be the difference between the original amount and the adjusted, higher refund amount.
For example, if your original refund was $2,500, but your new total tax refund is $3,500 with the adjustments based on your amended tax return, you’ll be issued an additional $1,000.
The IRS has increased flexibility for how to get your refund. For the 2021 tax year and onward, electronic filers can now request refunds to be directly deposited into a checking or savings account. You can even split the direct deposit into more than one account.
If amending your tax return results in a higher tax bill, you will need to make an additional tax payment. You can mail a check with the amendment or go online and make a payment at the IRS website after logging into their system. By making a payment now instead of waiting for the IRS to send an invoice, you can minimize the interest and penalties you'll owe.
Keep in mind that if you file an amended tax return on paper rather the e-filing, it can take the IRS eight weeks or longer to process the amendment. You can check the status of your amended return using the IRS' Where's My Amended Return? Wait about three weeks from the date you mailed your return for the information to show up in the IRS system.
If you amend your federal income tax return, you'll likely also need to file an amended tax return with your state. Each state has its own form to amend a tax return. TurboTax will select the right state forms for you when you prepare your federal amended return and supply instructions for submitting it to your state.
If your amended returns shows that you owed a lot in taxes or received a large refund, you may want to update your withholding . You can use the free Withholding Calculator from TurboTax to estimate your paycheck withholding, then complete a new Form W-4 and give it to your employer’s HR or payroll department.
