Year-End Close Checklist
This is a free year-end close checklist for accounting and bookkeeping firms — the full set of items to close a client's fiscal year, from final reconciliations and annual adjustments through 1099 prep, tax-ready workpapers, and partner sign-off. It builds on the monthly close and adds the entries that only happen once a year.
The year-end close checklist
Phase 1 — Confirm all 12 months are closed
- Verify every month in the fiscal year is reconciled and locked.
- Resolve any prior-period reconciling items still open.
- Confirm the opening balances tie to last year's filed return.
Phase 2 — Final reconciliations
- Reconcile all bank, credit card, and loan accounts through year-end.
- Confirm the AR and AP subledgers tie to the general ledger.
- Reconcile payroll to the annual 941s and W-2 totals.
- Reconcile sales tax payable to all filed returns for the year.
- Reconcile the fixed asset register to the balance sheet.
Phase 3 — Annual adjusting entries
- Record final depreciation and amortization for the year.
- Book the accrual-to-cash or cash-to-accrual conversion if needed.
- Record owner distributions, contributions, and equity movements.
- Adjust inventory to physical count and write off obsolete stock.
- Record bad debt write-offs and the allowance for doubtful accounts.
- Reclassify shareholder loans and related-party balances.
- Record accrued bonuses, PTO, and year-end payroll accruals.
- Book prepaid and deferred revenue true-ups.
Phase 4 — Tax and compliance prep
- Confirm all vendors have a W-9 on file; flag missing ones.
- Prepare and reconcile 1099-NEC / 1099-MISC totals.
- Reconcile W-2 wages to the general ledger payroll accounts.
- Identify book-to-tax differences (meals, depreciation, penalties).
- Assemble the tax preparer's package and supporting schedules.
Phase 5 — Review, report, and sign-off
- Confirm the year-end trial balance ties out.
- Review the full-year P&L and balance sheet for reasonableness.
- Prepare annual financial statements for the client.
- Second-reviewer check of all workpapers and adjustments.
- Partner sign-off; lock the fiscal year.
- Roll forward retained earnings and open the new year.
- Archive the complete year-end package.
How to use this checklist
Start the year-end close only after all 12 monthly closes are locked — chasing a clean December while October is still open wastes hours. Work the phases in order: reconciliations first, then annual adjustments, then tax prep, then review. Assign the tax-package assembly to whoever coordinates with the client's CPA so nothing is handed off twice. Keep a running list of book-to-tax differences as you go rather than reconstructing them at the end.
Common mistakes and tips
- Starting before the months are closed. Year-end adjustments made on top of unreconciled months get reversed. Close the year first.
- Missing W-9s discovered in January. Chase them during the year-end close, not on the 1099 deadline. Pair this with the 1099 preparation checklist.
- Forgetting the retained-earnings roll-forward. New-year balances won't tie if you skip it.
- No book-to-tax bridge. Give the tax preparer the differences documented, not a raw trial balance to untangle.

Frequently Asked Questions
When should year-end close start? Once the final month of the fiscal year is reconciled and all prior months are locked — typically the first few weeks after year-end, ahead of the tax deadline.
What's the difference between month-end and year-end close? Year-end close includes everything in a monthly close plus annual-only entries: depreciation true-ups, equity movements, 1099s, and the book-to-tax bridge for the return.
