Sometimes the IRS will catch your missing W-2 and send you a letter letting you know about the missing information and they will correct it for you or if you have other issues on your return they may reject it. So, in the meantime, you will need to wait to see if it is processed or not.
You will need to file an amended return. If you have already E-filed your tax return and need to make a change for any reason, then you have no choice but to wait until the IRS processes your E-filed return.
When the IRS cross-references your returns with other information, their programs will almost surely catch any mistake or incorrect information reported on your tax return.
Does the IRS Catch All Mistakes? No, the IRS probably won't catch all mistakes. But it does run tax returns through a number of processes to catch math errors and odd income and expense reporting.
Lying on your tax returns can result in fines and penalties from the IRS, and can even result in jail time.
In fact, the IRS cannot send you to jail, or file criminal charges against you, for failing to pay your taxes. ... But if your reason for not paying is because you didn't file or you committed a form of tax fraud (you intentionally lied on your return or tried to deceive the IRS), you could find yourself behind bars.
A client of mine last week asked me, “Can you go to jail from an IRS audit?”. The quick answer is no. ... The IRS is not a court so it can't send you to jail. To go to jail, you must be convicted of tax evasion and the proof must be beyond a reasonable doubt.
While the IRS itself cannot jail offenders, the courts can. Criminal investigations and charges start when an IRS auditor detects possible fraud during an audit of your returns. Courts convict approximately 3,000 people every year of tax fraud, signaling how serious the IRS takes lying on your taxes.
It may take the IRS up to 16 weeks to process amended returns. File Form 1040-X to amend. Taxpayers must file on paper using Form 1040-X, Amended U.S. Individual Income Tax Return, to correct their tax return.
If there is an anomaly, that creates a “red flag.” The IRS is more likely to eyeball your return if you claim certain tax breaks, deductions, or credit amounts that are unusually high compared to national standards; you are engaged in certain businesses; or you own foreign assets.
