If there is an issue with your tax return, the IRS may correct simple errors (like math mistakes) directly, or they may send a notice requesting more information or asking you to amend your return using Form 1040-X. This can result in delayed refunds, reduced refund amounts, or, if the error is severe, the return may be rejected.
If you make a mistake on your tax return, you usually correct it by filing Form 1040-X, Amended U.S. Individual Income Tax Return, to adjust income, deductions, or credits, but the IRS often corrects simple math errors or missing forms automatically; if you owe more tax, you'll incur interest and penalties, so fixing errors promptly with an amendment can reduce costs, but you must file it within the specified time frame, usually three years from the original filing date.
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 is reviewing your return, it may have questions about your wages and withholding, or credits or expenses shown on your tax return. The review process could take anywhere from 45 to 180 days, depending on the number and types of issues the IRS is reviewing.
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.
At the end of the day, even if the tax preparer is the one to make the mistake, the taxpayer is the one held liable by the IRS. That said, some contracts with taxpayers do include taking responsibility for errors.
