Failing to report all of your income on your tax return is a top audit trigger. That's because income that goes unreported on your tax return also goes untaxed. The IRS receives copies of your W-2 and 1099 forms and will automatically check to see that your reported income matches up.
You misreported your taxable income.
Math and transpose errors (e.g. entering $64,000 as $46,000) will be corrected by most tax software or the IRS automated under-reporter system. But if the misstatement of your income looks intentional and not in error, your tax return is likely to get flagged for audit.
Although the IRS audits only a small percentage of filed returns, there is a chance the agency will audit your own. The myths about who or who does not get audited—and why—run the gamut.
In recent years, the IRS has been auditing significantly less than 1% of all individual tax returns – and the trend has been towards fewer audits from one year to the next. Plus, most audits are handled solely by mail, meaning taxpayers selected for an audit typically never actually met with an IRS agent in person.
Key Takeaways. Your tax returns can be audited even after you've been issued a refund. Only a small percentage of U.S. taxpayers' returns are audited each year. The IRS can audit returns for up to three prior tax years and, in some cases, go back even further.
Audit trends vary by taxpayer income. In recent years, IRS audited taxpayers with incomes below $25,000 and those with incomes of $500,000 or more at higher-than-average rates. But, audit rates have dropped for all income levels—with audit rates decreasing the most for taxpayers with incomes of $200,000 or more.
Disproportionate Deductions & Excessive Expenses
However, deductions that are not in line with your business model or disproportionate to your income are a significant tax audit trigger. A large increase in deductions or expenses compared with the previous year is also likely to attract attention.
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.
If the IRS finds that you were negligent in making a mistake on your tax return, then it can assess a 20% penalty on top of the tax you owe as a result of the audit. This additional penalty is intended to encourage taxpayers to take ordinary care in preparing their tax returns.
In most cases, a Notice of Audit and Examination Scheduled will be issued. This notice is to inform you that you are being audited by the IRS, and will contain details about the particular items on your return that need review. It will also mention the records you are required to produce for review.
The IRS Review Process: Every Return Is Reviewed by Computer
Once the data is in the system, a computer checks the return for errors, such as mathematical errors; if none are found, the return is processed, and the IRS issues you either a refund or a balance due notice.
Can the IRS audit you 2 years in a row? Yes. There is no rule preventing the IRS from auditing you two years in a row.
Red flags may include excessive write-offs compared with income, unreported earnings, refundable tax credits and more. “My best advice is that you're only as good as your receipts,” said John Apisa, a CPA and partner at PKF O'Connor Davies LLP.
The Short Answer: Yes. The IRS probably already knows about many of your financial accounts, and the IRS can get information on how much is there. But, in reality, the IRS rarely digs deeper into your bank and financial accounts unless you're being audited or the IRS is collecting back taxes from you.
If you get audited and don't have receipts or additional proofs? Well, the Internal Revenue Service may disallow your deductions for the expenses. This often leads to gross income deductions from the IRS before calculating your tax bracket.
You cannot go to jail for making a mistake or filing your tax return incorrectly. However, if your taxes are wrong by design and you intentionally leave off items that should be included, the IRS can look at that action as fraudulent, and a criminal suit can be instituted against you.
Lying on your tax returns can result in fines and penalties from the IRS, and can even result in jail time.
Tip. You can take some comfort in the fact that the Internal Revenue Service audits less than 1 percent of all tax returns each year.
The chances of the IRS auditing your taxes are somewhat low. About 1 percent of taxpayers are audited, according to data furnished by the IRS. If you run a small business, though, your chances are slightly higher as about 2.5 percent of small business owners face an audit.
The IRS conducts tax audits to minimize the “tax gap,” or the difference between what the IRS is owed and what the IRS actually receives. Sometimes an IRS audit is random, but the IRS often selects taxpayers based on suspicious activity.
If you deliberately fail to file a tax return, pay your taxes or keep proper tax records – and have criminal charges filed against you – you can receive up to one year of jail time. Additionally, you can receive $25,000 in IRS audit fines annually for every year that you don't file.
Generally, the IRS can include returns filed within the last three years in an audit. If we identify a substantial error, we may add additional years. We usually don't go back more than the last six years. The IRS tries to audit tax returns as soon as possible after they are filed.
Yet less than 40 thousand of their returns were audited by the IRS in FY 2021 – just 4.5 out of every 1,000 of these returns[2]. This contrasts sharply with 13.0 out of every 1,000 of these lowest income returns that were audited last year by the IRS.
On the poorest households in America. The relevant statistics come to us via TRAC, a nonprofit research data center at Syracuse University. TRAC recently mined IRS statistics and determined that the agency audits households with less than $25,000 in income at five times the rate for anyone else.
