Yes, a high income significantly increases the likelihood of an IRS audit, as audit rates rise sharply for individuals with incomes exceeding $400,000, and even more so above $1 million. While overall audit rates are low, high earners face greater scrutiny due to more complex tax returns, which may include investments, business income, or large deductions.
That being said, it's important to be aware of “triggers” for IRS audits, below is a list of some of the more egregious items.
Audit odds are low, but the IRS uses automated programs to identify issues. Common red flags include unreported income and excessive deductions. High earners and digital currency users may face extra scrutiny. Maintaining strong records and specifical documentation can help prevent issues.
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.
There are five potential threats to auditor independence: self-interest, self-review, advocacy, familiarity, and intimidation. Any lack of independence compromises the integrity of financial markets.
Audit rates are generally highest for high-income taxpayers, taxpayers with business income, large corporations, and earned income tax credit claimants.
The IRS usually reviews receipts during an audit — if you don't have the receipts, you can sometimes use bank statements or credit card statements to prove your claims instead. Consequences of being audited without receipts can include additional taxes, interest, and financial penalties.
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.
Business- Section 44AB(a)
A business is required to get an income tax audit if its total sales/turnover/gross receipts exceed ₹1 crore in a financial year. However, the limit for tax audit has been relaxed to ₹10 crore if: Cash receipts ≤ 5% of total receipts, and. Cash payments ≤ 5% of total payments.
All non-federal entities that receive $1 million or more in federal grant funding or other federal assistance must complete an annual single audit to attest that they are using those funds correctly.

The Big 4 are the largest accounting and auditing firms in the world: Deloitte LLP (Deloitte), PricewaterhouseCoopers (PwC), Ernst & Young (EY) and Klynveld Peat Marwick Goerdeler (KPMG). They're so big that their joint revenue in 2024 was—you guessed it—$212 billion.
Failing to Report All Taxable Income
A mismatch sends up a red flag and causes the IRS computers to spit out a bill. If you receive a 1099 showing income that isn't yours or listing incorrect income, get the issuer to file a correct form with the IRS.
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 "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.
