Mistakes happen. Maybe you filed your tax return and later realized you forgot to report income, missed a deduction, entered something incorrectly, or received a tax document after you had already filed. The good news is that filing your tax return doesn't necessarily mean everything is set in stone.
In many situations, you can amend a previously filed tax return to correct or update information. However, whether you actually need to amend and how quickly you should do it depends on what changed.
What Is an Amended Tax Return?
An amended tax return is a corrected version of a tax return that has already been filed.
Amended U.S. Individual Income Tax Return.
An amendment allows you to show what was originally reported, what is being changed, and the corrected amounts. You'll also provide an explanation of why the return is being amended.
If the correction affects your state income tax return, you may also need to file an amended state return. The requirements and procedures vary by state.
Do You Need to Amend Every Mistake?
Not necessarily. Some minor errors don't require you to file an amended return.
For example, the IRS may automatically correct certain mathematical or clerical errors when processing a return. If a form or schedule is missing, the IRS may also contact you requesting additional information rather than requiring an amended return.
However, an amendment may be appropriate when the change affects your income, deductions, credits, filing status, dependents, or overall tax liability.
Some common reasons for amending a tax return include:
- Unreported or incorrectly reported income - such as receiving a W-2, 1099, or other tax document after filing.
- Missed deductions or tax credits - you may discover that you were eligible for a deduction or credit that wasn't included on the original return.
- Incorrect filing information - certain errors involving filing status or dependents may require an amendment.
- Corrected tax documents - an employer, financial institution, brokerage, or other payer may issue a corrected tax form after your return has already been filed.
- Business or investment adjustments - updated information involving business activity, investments, partnerships, or other financial transactions could affect your original return.
What If You Forgot to Report Income?
Discovering unreported income doesn't automatically mean you're in serious trouble, but it is something that should be addressed.
The IRS receives copies of many tax documents, including W-2s and 1099s, so its systems may eventually identify income that doesn't match what was reported on your return. Correcting the return yourself may allow you to address the issue before it becomes a larger problem.
If the additional income results in more tax being owed, interest and possibly penalties can continue to accumulate. For that reason, it may be beneficial to determine the additional tax and address the situation sooner rather than later.
What If the Amendment Results in a Refund?
An amended return isn't always about paying additional tax. Sometimes correcting a return means discovering that you actually overpaid.
Perhaps you missed an eligible credit, failed to claim a deduction, or reported something incorrectly that resulted in a higher tax bill. An amendment may allow you to claim the refund you were entitled to receive.
There are time limits for claiming refunds through an amended return. Generally, a refund claim must be made within three years from the date the original return was filed or two years from the date the tax was paid, whichever is later, although exceptions and special circumstances can apply.
This is one reason it's worth reviewing a prior return if you discover a significant mistake—you may not want to wait until the opportunity to claim a refund has expired.
Should You Amend While Your Original Return Is Still Processing?
Usually, it's best to allow the IRS to process the original return before submitting an amendment.
Filing an amendment while the original return is still being processed can potentially complicate matters. If you've just discovered an error immediately after filing, speak with a tax professional before submitting another return.
If you're expecting a refund from the original return, the IRS generally recommends waiting until you receive that refund before filing an amended return.
Will Amending a Tax Return Trigger an Audit?
One common concern is whether filing an amended return automatically causes an IRS audit.
An amendment does not automatically mean you will be audited. However, the IRS can review an amended return just as it can review an original return. The important thing is that the amended return is accurate and that you maintain documentation supporting the changes you are making.
Depending on the amendment, that documentation might include receipts, corrected tax forms, brokerage statements, business records, charitable contribution records, or other supporting information.
How Far Back Can You Amend a Tax Return?
Technically, an amended return may sometimes be filed for an older tax year, but whether doing so provides a financial benefit depends on the circumstances.
If you're trying to claim a refund, the time limits discussed above become especially important. If you're correcting previously unreported income or another issue that could increase your tax liability, different considerations may apply.
Older returns can also become more complicated when an amendment affects multiple years. For example, changing one year's return could affect losses, credits, depreciation, carryforwards, or other items reported in subsequent years.
What Happens After You File an Amended Return?
Amended returns generally take longer to process than original returns, so don't be surprised if you don't see an immediate change.
Keep copies of the amended return and all documentation supporting the changes. If additional tax is due, paying the balance as soon as reasonably possible may help limit additional interest and penalties.
If the amendment affects your state return, remember that correcting your federal return doesn't necessarily correct your state return automatically. You may need to amend both.
When Should You Talk to a Tax Professional?
Some amendments are relatively straightforward. Others can have consequences that aren't immediately obvious.
Consider speaking with a tax professional when:
- The amendment involves a significant amount of unreported income.
- You're correcting multiple tax years.
- Business, rental, investment, or cryptocurrency activity is involved.
- The change affects deductions, credits, depreciation, or carryforward amounts in later years.
- You've already received a notice from the IRS or a state taxing authority.
- You're unsure whether an amendment is actually necessary.
A tax professional can review both the original return and the new information to determine what needs to be corrected and whether the change affects any other tax years.
Found a Mistake? Don't Panic - Get It Corrected
Finding an error after filing your tax return can be frustrating, but tax returns can often be corrected. The important thing is determining whether an amendment is necessary and making sure the correction itself is accurate.
