For small business owners and taxpayers, one of the most inconvenient things to happen is to receive a notice of an IRS audit. For many people, it’s not always clear right away why they were chosen for an audit. It can feel totally random and even a bit unfair. 

The truth of the matter is that although your chances of being audited are small, there’s always still a chance that it could happen. Sometimes audits are completely random. Other times, something about your return was flagged for further review which led to the audit. Check out some of the most common causes of IRS audits so you can learn to avoid them. 

1. Math or Data Entry Mistakes

Math or data entry errors are easy to overlook. However, miscalculating your income or using the wrong formula or form for your taxes is no excuse when it comes to the IRS. If it’s a minor error, the IRS might simply contact you about it and ask for a correction. However, a larger error may lead to the IRS discovering other issues with your return, which could trigger an audit. 

Avoid math or data entry errors with the help of a professional accountant. They’ll not only serve as a preparer for your taxes, but they’ll also do a final check on your return to ensure no sneaky mistakes get through. 

2. Claiming Too Many Business Expenses or Losses

Small business owners use Schedule C to report business profits and losses. While you should take every deduction that you qualify for (after all, failing to do so is basically the same as leaving money on the table), you must still be mindful of the IRS rules. 

The IRS compares business returns against other returns from small business owners in similar occupations and fields. If you own a car repair business and deduct three times the average amount of travel expenses as other car repair business owners, they’ll likely notice and flag your return for a review. 

Other common business deductions that trigger audits include:

  • Unreported income, especially from third-party payment platforms 
  • Business deductions that are deemed unusual for your occupation 
  • Home office or vehicle deductions that include personal use. 

3. Outsized Charitable Deductions

You’re certainly entitled to a well-deserved charitable deduction if you made generous charitable contributions. However, it should go without saying that you should never, under any circumstances, falsify donation information. Don’t claim the deduction if you don’t have a receipt or documentation to back up a donation. 

Furthermore, if your charitable deductions seem out of proportion with your reported income, that’s certain to raise some flags at the IRS. For example, if you report an income of $50,000 and claim $25,000 in charitable contributions, you can bet that the IRS will have some questions. 

4. Underreporting Your Income

Perhaps one of the easiest ways to trigger an IRS audit is to underreport your income. Whether you choose not to report income you made from a side gig or forget to include a W-2 form, the IRS will likely find out about it.

One of the most common scenarios for underreporting income is when people fail to report earned 1099 income (nonwage income from activities like freelancing, stock dividends, etc.). Don’t forget: the IRS already knows about this income because the payer, whether that’s the bank or a freelance client, also sent a copy to the IRS! 

Even if it’s accidental, you’re still on the hook for reporting all of your income. Here are some common mistakes people make when reporting income that triggers audits:

  • Not accounting for all W-2 income — all the more likely if you had more than one job last year. 
  • Not reporting side gig money.
  • Excluding interest and earnings from investment or savings accounts. 
  • Not reporting capital gains on cryptocurrency trades, property sales, or stock trades.
