Yes, you will be notified by the IRS (https://www.irs.gov/individuals/understanding-your-irs-notice-or-letter) if they detect errors on your tax return. The IRS typically sends a letter or notice (via mail) explaining the discrepancy, such as a math mistake or mismatched income. If your refund is lower than expected or delayed due to an adjustment, they will inform you of the change.
The IRS is considering changing an amount on your tax return, due to an examination after it processed your tax return. This is called an audit. If it audits your return, the IRS will notify you by mail, and the notice will tell you if the audit will be handled by mail or in person.
If the IRS discovers the error, they will be writing you to notify you of the error and the tax, penalties, and interest due. They usually don't get around to this until a year or two after it was filed, although occasionally, with a simple math error, for example, you'll get a letter shortly after filing.
If the IRS thinks you made an error on your return, the IRS can change your refund. In that case, if you don't think the change was correct, you have 60 days to prove your case to the IRS and ask for a reversal. After 60 days, you'd need to file an amended return to reverse any errors and get your refund back.
You should amend your return if you reported certain items incorrectly on the original return, such as filing status, dependents, total income, deductions or credits. However, you don't have to amend a return because of math errors you made; the IRS will correct those.
Avoid These Common Tax Mistakes
If it is a math mistake, a wrong number is pulled from a chart, or a supporting form is missing, the IRS will send you a notice.
Getting a letter from the IRS can make some taxpayers nervous – but there's no need to panic. The IRS sends notices and letters when it needs to ask a question about a taxpayer's tax return, let them know about a change to their account or request a payment.
You may get a letter or notice from the IRS saying there's a problem with your tax return or your refund will be delayed. There are many reasons why the IRS may be holding your refund. You have unfiled or missing tax returns for prior tax years. The check was held or returned due to a problem with the name or address.
Your refund may also be delayed if numbers on your return don't match documents the IRS received about your income. Common mistakes can also cause delays, such as math errors or typos on your Social Security number, or if the direct deposit account doesn't match the filing status on your return.
You generally shouldn't worry if your refund is "still being processed," as it means the IRS is working on it, but it might take longer than the typical 21 days due to common issues like errors, incomplete information, or claiming credits like the EITC/ACTC. Worry only becomes necessary if you receive an IRS letter requesting more information or if the "Where's My Refund?" tool shows a specific problem like fraud, but typically, it just means a longer wait, not no refund at all.
An IRS notice may alert you to a mistake on your tax return or that it's being audited. You can verify the information that was processed by the IRS by viewing a transcript of the return to compare it to the return you may have signed or approved. You can access your tax records through your account.
The IRS can review your past three tax returns in audits — and up to six years if major errors are found. Audit odds are low, but the IRS uses automated programs to identify issues. Common red flags include unreported income and excessive deductions. High earners and digital currency users may face extra scrutiny.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
The Internal Revenue Service (IRS) will send a notice or a letter for any number of reasons. It may be about a specific issue on your federal tax return or account, or may tell you about changes to your account, ask you for more information, or request a payment.
Here are four options to find out your status with the IRS.
