Closing out your books the right way at year-end isn’t just a tax-season chore — it sets the foundation for next season’s planning, pricing, and goals. Here’s the checklist worth running through before December 31st, not after.
Reconcile Every Account
Every bank account, credit card, and loan should be reconciled to its statement balance. An unreconciled account is a place where mistakes — and sometimes money — quietly hide.
Review Your Chart of Accounts for Mistakes
Look for expenses miscategorized between COGS and overhead, personal expenses that snuck into business accounts, and any income sitting in the wrong bucket. These errors compound every month they go uncorrected.
Run a Final P&L and Compare It to Budget
Where did you land against the goals you set in January? This comparison is the single most useful input for setting next year’s targets — far more useful than guessing based on gut feel.
Prep 1099s Early
If you used subcontractors during the year, gather W-9s and payment totals well before the January filing deadline. Waiting until the deadline is the most common way this gets rushed and done poorly.
Meet With Your CPA Before Year End, Not After
A conversation in November or early December gives you time to make moves — equipment purchases, retirement contributions, timing of income — that actually affect this year’s tax bill. A conversation in February is just a report on decisions you can no longer change.
Set Next Year’s Targets Based on Actual Data
Use this year’s real numbers — gross margin by service line, labor efficiency, seasonal cash flow patterns — to set next year’s revenue and profit goals. Targets built on last year’s actuals are far more useful than round numbers picked out of ambition alone.

Do I need my bookkeeper and CPA to talk to each other? Yes — clean, categorized books handed to your CPA make tax prep faster, cheaper, and more accurate than a CPA reconstructing your year from scratch.
