What it is
The Month-End & Year-End Close Checklist is a controller-grade walkthrough of every task needed to lock the books with confidence at the end of a period. It organizes the close into four ordered phases, recording all activity, reconciling, posting accruals and adjustments, then reviewing and locking, and adds a dedicated set of extra steps that only apply at year-end. Worked in sequence, it is designed so your trial balance ties out the first time instead of after several rounds of corrections.
Each phase is broken into concrete tasks. Phase one confirms every bill, invoice, expense, payroll run, and depreciation entry is recorded. Phase two reconciles bank, credit-card, loan, AR, AP, inventory, prepaid, and fixed-asset accounts to their source. Phase three handles the judgment work, accruing earned-but-uninvoiced revenue and incurred-but-unbilled expenses, adjusting prepaids and deferred revenue, and revaluing foreign-currency balances. Phase four runs the trial balance, reviews the P&L and balance sheet against budget and prior period, secures a second-person review, and locks the period.
The year-end section layers on the tasks that close a full fiscal year: finalizing the fixed-asset register, reconciling sales-tax filings to the GL, preparing 1099 and payroll forms, booking tax provisions, rolling net income into retained earnings, and packaging schedules for your accountant or auditor. A closing callout reminds you to track days-to-close and post-close adjustment counts, the two metrics that reveal whether your process is improving.
What it's used for
The close is the most repeated and most error-prone process in accounting. This checklist is used to make it consistent, complete, and faster month over month.
- ✓ Running a disciplined, repeatable monthly close so financial statements tie out on the first attempt
- ✓ Ensuring every account is reconciled and every accrual is posted before the period is locked
- ✓ Standardizing the close so any team member can run it the same way, even when the controller is out
- ✓ Handling the additional year-end tasks, depreciation finalization, 1099 prep, and retained-earnings roll, without missing a step
- ✓ Shortening days-to-close by exposing which step in the cycle is consistently the bottleneck
- ✓ Enforcing a second-person review of material entries before statements are finalized
- ✓ Producing a clean package of statements and schedules to hand to an accountant or auditor
Who uses it
The close is owned by the accounting team but touches everyone who feeds it data. This checklist is written for the people accountable for accurate, on-time financials.
Context & good to know
A messy close is almost always a sequencing problem. Teams that jump straight to producing statements before every account is reconciled spend the rest of the month chasing the difference. The four-phase order in this checklist exists for a reason: you cannot reliably accrue or adjust until activity is fully recorded, and you cannot review meaningfully until reconciliations are done. Following the sequence is what turns a multi-day scramble into a predictable routine.
Reconciliation is the heart of the close. Bank, credit-card, and loan accounts must tie to statements, and the subledgers, AR aging, AP aging, inventory, prepaids, and fixed assets, must tie to their GL control accounts. When a control account and its subledger disagree, that gap is hiding an error you want to find now, in the close, rather than later, in tax prep or an audit. Modern accounting platforms like QuickBooks and Xero pull live bank feeds that auto-match cleared transactions, which removes much of the manual matching from this phase.
Accruals and adjustments are where the matching principle gets enforced. Revenue earned but not yet invoiced and expenses incurred but not yet billed both belong in the current period, regardless of when cash or the invoice shows up. Most accrual entries are written to reverse automatically at the start of the next period so the eventual invoice does not double-count. Deferred revenue and prepaid expenses move the other way, recognizing a slice each period rather than all at once.
The smartest teams treat the close as something to continuously shorten. Tracking days-to-close and counting the adjustments posted after you thought you were done is the fastest way to find the broken step. A close that drifts longer every month, or that always needs the same correcting entry, is telling you exactly where to invest in better process or better software.
