Red flags on tax returns that increase audit risk include failing to report all income (W-2/1099 mismatches), claiming excessive or disproportionate deductions, operating a cash-intensive business, and making simple math errors. Other common triggers include high-income earners, large charitable donations, home office deductions, and cryptocurrency transactions.
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.
Businesses that show losses are more likely to be audited, especially if the losses are recurring. The IRS might suspect that you must be making more money than you're reporting. Otherwise, why would you stay in business? Most likely to be audited are taxpayers reporting small business losses.
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.
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. You elected to apply the refund toward your estimated tax liability for next year.
Misspelled names. Likewise, a name listed on a tax return should match the name on that person's Social Security card. Entering information inaccurately. Wages, dividends, bank interest, and other income received and that was reported on an information return should be entered carefully.
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.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
Ten Red Flags that Could Trigger an IRS Audit
Remember, you will be contacted initially by mail. The IRS will provide all contact information and instructions in the letter you receive. If we conduct your audit by mail, our letter will request additional information about certain items shown on the tax return such as income, expenses, and itemized deductions.
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.
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.
If the deductions, losses, or credits on your return are disproportionately large compared with your income, the IRS may want to take a second look at your return. Taking a big loss from the sale of rental property or other investments can also spike the IRS's curiosity.
The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
Signs That The IRS Might Be Investigating You
The IRS "10k rule" primarily refers to the requirement for businesses and financial institutions to report cash transactions over $10,000 by filing Form 8300 (for businesses) or a Currency Transaction Report (CTR) (for banks), under the Bank Secrecy Act. This rule helps combat money laundering, tax evasion, and terrorist financing, requiring reporting for single transactions or related transactions totaling over $10,000 in cash within a year, with penalties for non-compliance.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
Audit rates are generally highest for high-income taxpayers, taxpayers with business income, large corporations, and earned income tax credit claimants.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
