Year-End Bookkeeping Checklist for Small Business Owners

Year-end is the part of the year nobody asks for. The work hasn't slowed down, the holidays are eating into your time, and on top of all that, you're supposed to close out your books and get ready for tax season. The point of a checklist is to break that work into pieces small enough that none of them feel impossible, even if you're doing this in fifteen-minute increments between everything else.

Below is what actually needs to happen before December 31 for most small businesses, plus a few items that only matter if they apply to your specific setup. Skip anything that doesn't fit your situation. There's no prize for ticking off boxes that aren't yours.

The core checklist (applies to almost everyone)

1. Reconcile every account through the end of the year.

Every bank account, every credit card, every loan account. Reconciling confirms that what's in your bookkeeping software matches what the bank says actually happened. If you've been putting reconciliation off, this is the time to catch up. This step-by-step reconciliation guide covers how to do it, and the post on why monthly reconciliation matters explains why this is the foundation everything else sits on.

2. Review your accounts receivable and send invoice reminders.

Pull up the list of every invoice that's still open. Anyone overdue gets a polite nudge. Anyone you forgot to invoice in the first place gets invoiced now. Money owed to you that you haven't collected is still part of your year, and the longer you wait, the lower your odds of actually collecting. This guide to tracking unpaid invoices in QBO walks through how to find and sort the ones that need attention.

3. Get W-9s squared away for every contractor you paid.

If you paid a contractor $600 or more this year, you'll need to issue a 1099-NEC in January, and you can't do that without a W-9 on file. Now is the time to chase down anyone you don't have one for. Going forward, collect W-9s before any money moves. This bookkeeping mistakes post covers why that matters.

4. Clean up your chart of accounts.

If accounts have piled up, accounts have gotten weird names, or things have been categorized inconsistently, year-end is a good moment to fix it. A clean chart of accounts makes your year-end reports actually useful, and it makes next year easier. This cleanup guide walks through it.

5. Run your year-end reports.

At a minimum: profit and loss for the full year, balance sheet as of December 31, and a statement of cash flows if you use one. These are what your tax preparer will want, and they're also the snapshot you can actually learn from.

6. Cancel subscriptions you're not using.

This isn't strictly bookkeeping, but year-end is when you have a clean view of what you actually paid for over the past twelve months. Pull up the list. Anything you haven't used in six months goes. Anything that auto-renewed in January and never got opened gets canceled before it hits again.

7. Compare what happened to what you planned.

If you set any budget or revenue targets for the year, look at what actually happened against what you projected. The point isn't to feel bad about missing a number. It's to figure out where your guesses were off so next year's guesses are better.

If any of these apply to your business

8. Inventory count. If you sell physical products, count what you have on hand. Match the count to what your books say you have, and adjust the books to match reality.

9. Year-end bonuses and W-2 prep. If you have employees, this is the moment to handle bonuses and to verify that every employee's name, address, and Social Security number is current. W-2s go out by January 31, and corrections are a hassle.

10. Distributions and owner draws. If you're an S-corp, partnership, or LLC taxed as either, make sure any distributions taken during the year are properly documented. This affects your taxes and your basis. If you're not sure how distributions are categorized in your books, that's worth a conversation with your tax preparer or bookkeeper before you file.

One last note

If reading this list made your stomach drop because none of it has been done and December is half over, that's information, not a verdict. You have two real options: pick the highest-impact items (reconciliations, W-9s, A/R) and get those done, or hand the whole thing off.
