How to Prepare for a Small Business Audit: What to Expect
Let’s talk about the one thing no small business owner wants to hear: “You’ve been selected for an audit.”
Deep breath. You’re not in trouble. An IRS audit is not the end of the world—and in most cases, it’s just a routine review. But the key to surviving (and even thriving through) an audit is knowing what to expect and being prepared.
In this post, we’ll walk you through why audits happen, how to get ready, and what steps you can take now to avoid panic later.
Why Small Businesses Get Audited
You might be wondering: Do small businesses get audited often? The truth is, not really. According to recent IRS data, the audit rate for small businesses is below 1%. However, certain red flags can increase your chances, such as:
- Reporting unusually high deductions compared to income
- Misclassifying employees as independent contractors
- Claiming a lot of losses year after year
- Failing to report income (especially cash or 1099 income)
Sometimes, it’s just random selection. But even if your books are clean, it helps to be ready.
What to Expect During an Audit
The IRS will typically notify you by mail. You won’t get a call out of the blue (and if you do—it’s likely a scam). The audit might take place via mail (correspondence audit), in an IRS office (office audit), or at your place of business (field audit).
From the moment you get the letter, the best strategy is to stay calm, respond promptly, and organize everything.
Step-by-Step: How to Prepare for a Small Business Audit
1. Get Your Records in Order
Start by pulling together your documentation for the year in question. This may include:
- Bank and credit card statements
- Invoices and receipts
- Mileage logs
- Payroll and contractor payments
- Your tax return and supporting schedules
A great resource to guide your prep is a small business audit checklist. It ensures you have all the paperwork an auditor might ask for, in one place.
2. Match Your Books to Your Return
This is critical. Double-check that your income and expenses in QuickBooks, Wave, or whatever software you use line up with what you reported. The IRS will compare these numbers, and discrepancies could lead to additional questions—or penalties.
3. Only Provide What’s Requested
More is not better here. If the IRS asks for backup on your meals expenses, don’t send them your full ledger of equipment purchases. Stick to exactly what’s asked for, nothing more, nothing less.
What Does an Audit Cost You?
The average cost of an audit for a small business isn’t just about money. It’s time, stress, and the potential for lost business while you're chasing down documents. Professional help can ease the burden, but even then, the distraction is real.
By contrast, investing a little time each month to stay organized can save you exponentially when (and if) an audit comes.
Can You Avoid an Audit Altogether?
There’s no guaranteed way to avoid audits—but you can reduce the chances by:
- Filing on time
- Reporting all income (including 1099s)
- Avoiding excessive deductions without documentation
- Using professional tax help when needed
You might ask: How often do small businesses get audited if they’re organized and clean? Less than 1 in 100. Staying sharp pays off.
