25-Step Checklist
A. Pre-close (Steps 1-6)
- Freeze close calendar and PBC owners.
- Confirm materiality with auditors — see Audit Procedures.
- Schedule inventory observation — see Inventory.
- Scrub vendor masters for 1099s and W-9s.
- Confirm loan, lease, and equity activity — see ASC 842.
- Lock chart changes — see Chart of Accounts.
B. Cut-off and substance (Steps 7-16)
- Reconcile all cash; clear >30-day outstanding.
- Age AR/AP; reserve and accrue GRNI — see AP Fraud.
- Tie payroll clearing to returns — see Payroll and Multi-State.
- Test revenue cut-off to ASC 606.
- Roll prepaids, fixed assets, leases.
- Post tax provision with Year-End Tax Planning inputs.
- Review related parties and subsequent events to report date.
- Run flux vs prior year and budget with owner commentary.
- Controller + CFO review and lock.
- Export GL + audit logs — see QuickBooks vs Xero.
C. Filing and PBC (Steps 17-25)
- File 1099/W-2 and state equivalents.
- Reconcile filings to GL (no plugs).
- Assemble PBC binder: recs, agings, contracts, minutes.
- Provide Internal Controls walkthroughs.
- Track auditor requests in one log; no email-only support.
- Clear management review notes with retest where needed.
- Minute subsequent events through report date.
- Archive binder immutable 7 years.
- Post-mortem: adjustments root cause and control fix.
Worked Example: The $90k Cut-Off Error
December 31: warehouse ships $90k of product at 11pm; invoice dated January 2 (next batch run). Books show January revenue; inventory still shows the goods on hand. Both wrong. Fix: accrue December shipment (debit AR, credit revenue per ASC 606 transfer of control), relieve inventory, and reconcile the shipping log to the invoice register for the last 5 shipments and first 5 of January — with BOL dates, not invoice dates, as truth. Then fix the root cause: invoices must generate from shipment, not from batch schedule. One cut-off error of this size moves EBITDA covenants — see Debt — and, uncaught, becomes a prior-period restatement next year.
Soft Close vs Hard Close (Run Both)
| Soft close (Dec 31 + 2 days) | Hard close (mid-January) | |
|---|---|---|
| Purpose | Flash P&L for management, freeze estimates | Audited numbers, filed returns support |
| Accruals | High-level, prior-month run-rates | Invoice-level, evidenced |
| 1099/W-2 inputs | Preliminary scrub | Locked, reconciled — see Filing Deadlines |
| What it prevents | January surprises | Audit adjustments |
Teams that skip soft close discover the $90k problem in February, when fixing it means restating January management reports and re-explaining results to the board. The soft close costs two days; the alternative costs credibility.
Tax Provision Tie-Out (Controller’s Hardest Page)
| Book item | Tax treatment | Bridge |
|---|---|---|
| Depreciation $400k book | $650k MACRS + bonus | $250k add-back to deferred — see Fixed Assets |
| 174 R&D $600k expensed | Capitalize, amortize ~$60k | $540k add-back — see Year-End Tax Planning |
| Meals $40k | 50% limit | $20k add-back — see Business Meals |
| State NOLs | Varies by state | Valuation allowance analysis per jurisdiction |
The provision memo is the document the tax partner and the auditor both read first. Reconcile effective rate to statutory with every bridge item labeled; unexplained rate swings draw questions from both sides. File with the return workpapers and retain per Record Retention.
KPIs to Report
- Days to hard close, PBC timeliness, adjustment count, repeat findings.
- Report to Audit Committee.
FAQ
What causes most delays?
Late AP, payroll tie-out gaps, and missing revenue support. Fix owners in October.
Should tax and audit share a binder?
Yes, single source with tax provision separate — avoids version drift.
Next Steps
- Freeze PBC calendar this week.
- Scrub 1099/W-9s in November.
- Lock hard close date and hold it.
