IRS Insider: Why Year-End Receipts Make or Break You

Every January, small business owners scramble to “get their receipts together.”

Some find them in glove boxes. Others in junk drawers, inboxes, or half-torn envelopes. And some just shrug and hope their bank statements will be enough.

But from the IRS side? Missing or incomplete receipts can undo months of hard work—because records are the backbone of every deduction.

Let’s talk about why those receipts matter more than you think, what the IRS really looks for, and how to make this your easiest year-end ever.

1. The IRS Doesn’t Accept “Bank Statements Alone”

A common misconception is that bank or credit card statements are “good enough.”

They’re not.

Statements show that you spent money, but not why.

When I worked as an IRS Agent, this was one of the first tests we used in an audit.Per IRM 4.10.7.3.8 (Evaluation of Evidence), agents are required to verify “the amount, time, place, and business purpose” of every expense.

If your statement says:

12/15/25 – Home Depot – $214.77

That doesn’t prove whether you bought office shelving, personal Christmas lights, or both.

Without a matching receipt or clear explanation, that deduction could be denied.

2. The Burden of Proof Is on You

It’s not the IRS’s job to prove you didn’t spend business money—it’s your job to prove you did.

Under IRC §6001 and the Internal Revenue Manual, small businesses must keep records that “clearly establish income and deductions.”

That means receipts aren’t optional. They’re your defense file.

When you can show receipts tied to your books, your credibility goes way up—and audits go way faster.

3. The Year-End Danger Zone

Here’s what typically happens around the holidays:

• You buy supplies, gifts, or materials.

• You mix personal and business charges.

• You forget to label or categorize them.

Then, when you or your tax preparer look back in March, no one remembers what that $83 Amazon charge was for.

That’s how deductions disappear—and how perfectly legitimate expenses turn into gray areas.

4. What “Good Recordkeeping” Looks Like

The IRS doesn’t require fancy software. It just wants clarity.

Here’s a no-fluff checklist for year-end receipts:

✅ Save every business receipt—digital or paper.

✅ Write notes directly on the receipt: “client lunch,” “supplies for Smith job,” etc.

✅ Snap a photo of each receipt and upload to Google Drive or Dropbox.

✅ Match each receipt to a category in your bookkeeping spreadsheet.

✅ Store all year-end receipts together (folder labeled “2025 Business Receipts”).

That’s it. No apps, no subscriptions—just good habits.

5. The IRS Audit View

When agents review a business, they look for consistency:

• Do totals match what’s reported on the tax return?

• Are categories logical (no “miscellaneous” every month)?

• Do receipts tie to real, specific business activities?

If your records are complete and organized, most agents move on quickly.If they’re missing or inconsistent, they start asking more questions—and that’s where audits drag on.

Good documentation doesn’t just protect your deductions—it shortens your audit timeline.

6. Why Year-End Is the Best Time to Fix It

Catching up now saves you panic later.

Spend one afternoon organizing your receipts before the new year:

• Sort them by month.

• Match them to your expense tracker.

• Write notes where needed.

You’ll walk into tax season with everything ready—and that confidence is priceless.

7. Tools That Make It Easy

You can use simple tools to stay on top of receipts going forward:

• Scanner apps (Adobe Scan, Genius Scan) for digital uploads

• Google Drive or Dropbox for organized folders

• Excel  to log expenses as you go

8. When Receipts Are Missing

If you’ve already lost some receipts, don’t panic. You can reconstruct them.

Pull:

• Bank and credit card statements

• Vendor invoices or order confirmations

• Calendar or email history for business meetings

Attach supporting evidence to show intent and purpose.

Per IRM 4.10.7.3.8.2, reconstructed records are acceptable when they’re consistent and credible.
