Yes, the IRS will notify you if they detect mistakes, such as math errors, missing forms, or inconsistencies with documents like W-2s and 1099s. Notifications usually arrive by mail (not email or phone) and may arrive within a few weeks to several months after filing. The IRS may correct simple errors automatically or ask you to file an amended return.
If there's a mistake and the IRS sent you a notice or returned the form. If information is missing, the IRS will either return the form or send you a notice asking for specific information it needs to finish processing your tax return.
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.

If the IRS is reviewing your return, the review process could take anywhere from 45 to 180 days, depending on the number and types of issues the IRS is reviewing. Follow these steps if you know you made a mistake, before the IRS contacts you.
You may receive penalty relief where a penalty would otherwise be imposed if you have made an error in your income tax return or activity statement.
In general, the Internal Revenue Code, regulations, and case law do not impose a duty on taxpayers to file an amended return when they discover that an error was made in good faith on a past return.
Some common culprits that could cause a rejection are mismatched names, SSNs, employer EINs, electronic signature numbers, or an expired TIN. File early. Another action to take is to file your return early. This gives identity theft criminals less time to file a fraudulent return using your information.
IRS audits are triggered by discrepancies the IRS's automated systems catch, like unreported income from 1099s, claiming excessive deductions (charity, business meals, home office) compared to your income bracket, large business losses, math errors, significant income jumps, or claiming hobby losses as business expenses, with higher-income earners generally facing more scrutiny.
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.

You (or your tax pro) will meet with the IRS agent at an IRS office. The IRS usually starts these audits within a year after you file the return, and wraps them up within three to six months.
