Clean books before year-end: a QuickBooks cleanup checklist for small business owners

Your tax return is only as good as your books. With year-end approaching, now is a practical time to fix them.

Cleaning up in November means your year-end numbers are ready when your tax preparer asks for them in January. Clearer books also help with decisions that still depend on this year's results—equipment purchases, owner pay, and retirement planning where your plan's rules allow. Not every retirement contribution is due December 31.

The checklist

1. Reconcile every bank and credit card account through October. Every account, including ones you rarely use. Unreconciled accounts often delay a return.
2. Clear the uncategorized and "ask my accountant" accounts. Anything still parked there at year-end has to be sorted before it can be reported correctly.
3. Match your payroll totals to your payroll reports. Wages and payroll taxes should agree with those reports. Review owner pay separately according to how your entity is structured.
4. Review your open invoices and bills. Look at old receivables and unpaid bills with your tax preparer. Treatment depends on your accounting method; unpaid invoices are not automatically a tax write-off. Record bills you owe in the right year.
5. Collect current W-9s from U.S. contractors and other service vendors before year-end. Do this even when a vendor may fall under the reporting threshold—you still need accurate payee information. For 2026, Form 1099-NEC generally applies when you pay $2,000 or more in nonemployee compensation, subject to applicable payee and payment exceptions; confirm which payments and payees require reporting. Forms 1099-NEC are due Monday, February 1, 2027.
6. Separate personal and business spending. Move personal charges out of the business accounts, or record them in the way that fits your entity—owner draws, distributions, or shareholder loans—not automatically as draws.
7. Check loan and asset balances. Loan balances should match lender statements. Gather records of equipment bought this year and confirm with your preparer what should be capitalized, expensed, or covered by a tax election. Book coding and Section 179 elections are not the same thing.
8. Take a look at your profit and loss. Look for categories much higher or lower than last year. Unusual numbers are worth checking before year-end.

What to have ready for your tax preparer

• Year-end bank and credit card statements
• Profit and loss and balance sheet
• Payroll reports for all four quarters
• Loan statements and a list of any equipment purchased or sold
• Prior-year return
