The end of the year doesn't have to mean a frantic scramble through a shoebox of receipts. With a clear checklist and a little discipline, you can close your books cleanly, hand your CPA an organized package, and walk into the new year actually knowing where your business stands.
Here's the catch worth saying up front: businesses that keep clean monthly books barely have a "year-end scramble" at all. If you've been reconciling and categorizing all year, this checklist is mostly a quick review. If you haven't, it's your roadmap to getting caught up. Either way, work through these steps in order.
1. Reconcile every account through year-end
This is the foundation. Reconcile all of your accounts against their official statements so your books match reality:
- Every business bank account
- Every business credit card
- Loans and lines of credit (confirm the remaining balance and the interest vs. principal split)
If a reconciliation won't balance, that's a signal something is missing or duplicated — fix it now, not in April.
2. Review accounts receivable
Go through everything customers still owe you. Chase down open invoices while the work is still fresh in everyone's mind, and make a clear-eyed decision about anything that genuinely won't be collected. Writing off a truly uncollectible invoice keeps your receivables honest — just talk to your CPA about how to handle the write-off correctly for your situation.
3. Review accounts payable and record all bills
Make sure every bill you owe is entered, including ones that arrived late in December for work or supplies from earlier in the year. Unrecorded expenses understate your costs and overstate your profit — which can mean a nasty surprise at tax time.
4. Confirm every transaction is categorized correctly
Scan your transactions for anything sitting in "Uncategorized," "Ask My Accountant," or an obviously wrong account. Consistent, accurate categorization is what makes your reports — and your tax return — meaningful.
5. Review your chart of accounts
Year-end is a good time to tidy up. Merge duplicate accounts, retire categories you no longer use, and make sure the structure still reflects how your business actually operates. A clean chart of accounts makes next year's bookkeeping faster.
6. Account for fixed assets and depreciation
List any major equipment, vehicles, or property you bought or sold during the year. Depreciation rules are nuanced and change over time, so this is firmly a work-with-your-CPA item — give them the purchase details and let them determine the right treatment.
7. Take inventory (if applicable)
If you carry inventory, do a physical count at year-end and reconcile it against what your books say you have. Adjust for shrinkage, damage, or counting errors so your cost of goods sold is accurate.
8. Gather contractor info and prepare for 1099s
Pull together the totals you paid to independent contractors and vendors, and make sure you have a completed W-9 on file for each one. The rules and thresholds for 1099 reporting are set by the IRS and can change, so confirm current requirements with IRS guidance and your CPA before filing — and request any missing W-9s now rather than in January.
9. Review payroll records
If you have employees, reconcile your payroll for the year: wages, withholdings, and any benefits or reimbursements. Confirm employee details are current so year-end payroll forms go out correctly. Payroll reporting has its own deadlines and rules — check current IRS and state guidance, and lean on your payroll provider or CPA.
10. Review your P&L and balance sheet
Pull your profit & loss and balance sheet for the full year and actually read them. Compare against last year and against your expectations. Anything that looks off — a category that's way too high or too low, a balance that shouldn't be there — is worth investigating before you close the books.
11. Back up and organize your documentation
Make sure receipts, invoices, statements, and supporting documents are saved and organized. A reliable backup of your accounting file and records protects you if you ever need to substantiate something later.
12. Assemble a clean package for your CPA
Finally, pull it all together: finalized reports, reconciliations, fixed-asset details, contractor totals, and any notes on unusual items. The cleaner the package, the faster — and often cheaper — your tax prep will be.
