7 Things Every Small Business Should Have in Place Before an Audit

1. A Reliable Bookkeeping System (Not a Pile of Spreadsheets)

This is your financial backbone. Whether you use QuickBooks, Xero, or another platform, your books should be updated monthly, reconciled with bank statements, and backed up.

💡 Pro Tip: If your books are behind or messy, outsource cleanup now before it becomes an emergency.

2. Receipts and Documentation for ALL Deductions

Every deduction you take—meals, travel, equipment, home office—needs proof. The IRS wants to see the who, what, when, where, and why.

💡 Pro Tip: Use tools like Dext or Expensify to automatically save and categorize receipts in real time.

3. Clear Separation Between Business and Personal Finances

Blurring the line between personal and business expenses is a huge audit red flag. Every dollar in and out of your business should flow through a dedicated business account.

💡 Pro Tip: If you haven’t already, open a business checking account and apply for a separate business credit card today.

4. Proper Classification of Contractors vs. Employees

Misclassifying workers can lead to major penalties. If someone works under your direction and on your schedule, they might be an employee—not an independent contractor.

💡 Pro Tip: If you’re not sure, consult with a payroll specialist or HR advisor before issuing another 1099.

5. Copies of Filed Tax Returns and Supporting Documents (At Least 3 Years Back)

The IRS can go back three years (and sometimes more) in an audit. Keep digital and physical copies of your returns, W-2s, 1099s, depreciation schedules, and all supporting documentation.

💡 Pro Tip: Cloud storage (like Google Drive or Dropbox) is your friend—just make sure it’s organized and secure.

6. A Mileage Log (Not Just a Guess)

If you deduct vehicle expenses, you need actual records—not estimates. The IRS wants logs showing dates, miles driven, purpose, and locations.

💡 Pro Tip: Use an app like MileIQ or TripLog to automate mileage tracking.

7. An Accountant or Tax Professional on Speed Dial

Don’t wait for an audit to build your support team. Having a pro who knows your books, understands your return, and can represent you during an audit is a major advantage.

💡 Pro Tip: At BizAccountants, we help our clients stay audit-ready year-round, not just during tax season.

🛑 What Happens If You’re Not Audit-Ready?

Scrambling to find receipts, explain inconsistencies, or fix messy books under pressure leads to:

• Delays
• Penalties
• Missed deductions
• Stress (lots of it)

Worst case? You owe back taxes, interest, and fines.

Best case? You lose time and energy that could’ve been spent growing your business.
