Tulsa Bookkeeping Checklist for Year-End Tax Prep

As the year wraps up, Tulsa small business owners need to make sure their books are clean, accurate, and ready for tax season. Whether you use QuickBooks, spreadsheets, or a custom system, these five steps will help you stay organized and avoid costly mistakes. The earlier you start, the smoother your December will be.

1. Reconcile All Bank and Credit Card Accounts

Start by reconciling every business account. Match your transactions to bank and credit card statements to catch duplicates, missed entries, or fraud. This step ensures your reports reflect reality. If you’re behind, our bookkeeping services include monthly reconciliations and cleanup support.

2. Categorize Expenses Correctly

Next, review how your expenses are labeled. Meals, travel, office supplies, and contractor payments should be separated for accurate deductions. Mislabeling can trigger IRS scrutiny or missed write-offs. Need a refresher? The IRS expense guide breaks down what counts.

3. Record Outstanding Invoices and Payments

Don’t forget to log unpaid invoices and incoming payments. If you use accrual accounting, this step is essential for accurate year-end reporting. Even cash-based businesses benefit from tracking receivables. We cover this in our tax planning consults, especially for clients preparing for growth.

4. Review Payroll and Contractor Records

Verify that all W-2 and 1099 payments are logged correctly. Starting this year, businesses filing 10 or more returns must file electronically. December is your last chance to get compliant. The IRS e-file rules explain what’s required and how to prepare.

5. Generate Tax-Ready Financial Reports

Finally, run your Profit & Loss, Balance Sheet, and Cash Flow reports. These give you a snapshot of your business health and help your CPA prepare accurate returns. If your reports look off, it’s a sign your books need cleanup. Visit our News & Information hub for more tips on preparing for tax season.
