What is a year-end close?

Year-end close is the accounting process of finalizing all transactions, making adjusting entries, closing revenue and expense accounts to retained earnings, and preparing annual financial statements at the fiscal year end. For professional service firms, year-end close provides accurate annual results and prepares books for tax filing.

Key characteristics

• Finalizes annual transactions

• Includes all adjusting entries

• Closes income statement accounts

• Updates retained earnings

• Prepares for tax filing

• Resets for the new year

Why it matters for professional service firms

Year-end close determines final annual results and sets the foundation for tax return preparation. An incomplete close means inaccurate financials and tax filings. Professional service firms should complete the year-end close promptly to enable timely tax preparation.

Real-world example

Sarah's year-end close process: December transactions finalized by January 10, adjusting entries (accruals, deferrals, depreciation) by January 15, financial statements reviewed by January 20, books closed January 25. Revenue and expense accounts are zeroed to retained earnings. Clean financials provided to the tax preparer on February 1. Timely close enabled early tax filing.
