New Jersey Municipalities: December 31 Year-End Close Starts in October

September 1, 2026

Why New Jersey Municipalities Should Start the December 31 Close in October, Not January

Most of the audit findings a New Jersey municipality receives in the spring were created in November and December of the prior year, by people who were busy with other things and assumed there would be time later. There is no later. The close happens once, the books shut, and everything that was not cleaned up becomes something the registered municipal accountant writes up six months on. PM Consultants places CMFOs and finance staff in towns across the state, and the pattern we see most often is a finance office that lost someone in the fall and never got the last quarter under control.

What Actually Has to Be Finished Before December 31

The close is a sequence, not a single event. Bank accounts have to be reconciled through December and tied to the trial balance. Interfunds have to be liquidated, not carried. Open purchase orders have to be reviewed line by line so the reserve for encumbrances reflects real commitments. Grant receivables and payables that have sat for years without activity need governing body action to cancel them. Tax overpayments, developer escrows, and trust balances get verified. Petty cash and change funds get counted and returned.

None of it is difficult work. All of it takes weeks, and almost all of it requires someone to chase a department head who has not answered an email since October.

Why November and December Are the Last Clean Chance to Fix a Line Item

Under N.J.S.A. 40A:4-58, transfers between appropriation line items may be made during the last two months of the fiscal year. That window is how a town corrects the salary line that ran hot, the legal line that absorbed an unexpected matter, or the insurance line that never had enough in it to begin with. Transfers cannot be made to or from emergency appropriations, and no transfer may be made from an appropriation outside the CAP to one within it.

A finance officer working from a full set of reconciled books in early November can see exactly which lines will finish short and move money while the option is still available. One working from books that stopped being reconciled in September finds out in February, after the year is closed, when the only remedy left is an overexpenditure that shows up as a deferred charge in the following year's budget. Towns rarely notice the difference until the auditor explains it to the governing body.

How Long Appropriation Reserves Stay Available

Unexpended balances carried forward at the close of the fiscal year remain available until they lapse at the close of the succeeding year, under N.J.S.A. 40A:4-59, and can be used to meet claims, commitments, or contracts incurred during the preceding fiscal year. Transfers among those reserve balances may be made during the first three months of the succeeding year.

That first quarter matters more than people expect. Invoices for November and December work land in January and February, often from vendors who bill slowly, and they have to be charged against the prior year's reserves rather than the new budget. A department that sends its December invoices in March has forced a decision nobody wanted to make. The balances that go unused eventually lapse to fund balance, which is fine, though a town that consistently lapses large reserve balances is telling its auditor and the Division something about how the budget was built.

The Filing Sequence That Begins January 31

The Annual Debt Statement is due January 31 under N.J.S.A. 40A:2-40. The Annual Financial Statement follows under N.J.S.A. 40A:5-12, with the filing date for calendar-year municipalities and counties now set at March 10 by statute rather than by annual extension. The annual audit is due within six months of the close of the fiscal year under N.J.S.A. 40A:5-4. Budget introduction follows in late March.

Each of those depends on the one before it. A CFO who is still reconciling October cash in February is not producing an AFS on March 10, and the penalties for late filing under P.L. 2025, c.185 are considerably heavier than the per-day fines towns used to shrug off. The Annual Debt Statement in particular gets treated as a formality until the town needs to sell notes and discovers its reported debt condition does not match its records.

What a Fall Vacancy Does to All of It

A CMFO who resigns in October leaves at the exact moment the close should be starting. The town appoints someone acting, that person keeps disbursements moving and payroll running, and the reconciliation and cleanup work quietly stops. Nobody notices in November. In April, the audit comes back with findings on cash reconciliation, interfunds, and encumbrances, and the corrective action plan promises improvements that require staff the town still does not have.

The towns that come through this well are the ones that put a credentialed professional in the seat within a few weeks and gave that person a clear instruction: close the year properly, even if the search for a permanent hire runs into next summer.

If your finance office is heading into the fourth quarter short-handed, or you are looking at a December close that nobody currently on staff has done before, PM Consultants can put an experienced CMFO or finance professional in place while you sort out the permanent hire.
